The second half of the twentieth and the beginning of the twenty-first century are marked by two processes that pose a serious threat to the sustainable development of the world in the near future. These are the population explosion in certain parts of the world and climate change. At the beginning of the second millennium the world population was only 300 million, today it exceeds 8 billion and by the middle of this century it will reach 10 billion. At the same time, throughout human history, people have lived and worked in an identical way, now for the first time we have industry, transport, industrial animal husbandry that seriously pollute the natural environment, the consequences of it are unpredictable and they are bound to affect people. And this is already occurring, with increasingly acute drinking water shortages catalysing existing ethno-religious conflicts and generating new ones. The ones we have analyzed in this paper are along the Nile and in the Middle East along the Tigris, Euphrates and Jordan rivers. Already more than half of African countries are in water stress, and nearly a third in water disaster, including one, Uganda, which according to UN projections is expected to have a population growth between 2000 and 2050 of 302%! And when we talk about climate change and water conflicts, we need to act immediately so that tomorrow is not too late!. [ABSTRACT FROM AUTHOR]

This paper presents findings on the role of the university and institutional support for climate change education interventions at two universities in East Africa. The findings were part of a larger study on opportunities and challenges for climate change education at universities in the African context: A comparative case study of Makerere University in Uganda and University of Dar es Salaam in Tanzania. A comparative multiple case study design was adopted collecting qualitative data from 58 lecturers, researchers, administrators and students on climate change related programmes at the two universities. Data was collected through semi-structured in-depth interviews and focus group discussions. Analysis was done using thematic analysis based on Braun and Clarke's (Qualitative Research in Psychology, 3(2), 1–41, 2006) approach with the help of MAXDA software. Findings from the cross-case analysis revealed similarities and differences in perspectives and multiple realities of participants at both universities regarding the role of the university and institutional support for climate change education in the African context. The findings shed light on the context and nature of climate change education interventions and how these are supported at both universities. The study contributes to empirical literature on the role of higher education in addressing climate change and the institutional support to the interventions in the African context.

In this paper we examine whether there are significant gender differences in the adoption of climate‐smart agricultural (CSA) practices in sub‐Saharan Africa. Using individual‐level data from four sites in Kenya, Uganda and Senegal, our empirical analysis provides robust evidence that men have a higher likelihood of adopting high‐return CSA practices including modern chemical fertiliser, improved high‐yielding varieties and drought/pest tolerant livestock practices. In contrast, women tend to have a higher likelihood of adopting low‐risk and low‐return traditional CSA practices such as water harvesting, crop covering, rangeland management and pest management. Our subsample analysis shows significant heterogeneity in the gender gap across countries. The results of the decomposition of the observed gender gap show that personal values and norms, access to weather and production information and farm characteristics are important factors that explain the gender differential in the likelihood of CSA adoption. Our findings imply that equalising access to key resources such as plots of land, information and decision making power will be crucial to close the gender gap in the adoption of CSA practices. This is particularly important given the differential impacts of climate change between men and women in sub‐Saharan Africa. [ABSTRACT FROM AUTHOR]

The complex linkage between environment, climate change and migration is increasingly capturing global debate. Uganda faces widespread environmental degradation and high vulnerability to climate change impacts that cause livelihood hardships, inducing human mobility. However, the environment, climate change and migration nexus is not well understood and documented, although advocacy to address the livelihood challenges associated with environmental and climate-induced migrations is on the rise. This paper addresses this knowledge gap and presents findings from a review of literature, complemented by key informant interviews and group discussions conducted in the Karamoja, Mt. Elgon and Teso sub-regions of Uganda. The findings show that some socio-economic hardships that cause migrations like natural resources scarcities (water, pastures and fertile soils), hunger and food insecurity and conflicts are linked to slow-onset processes/events related to environmental degradation, rising temperatures and desertification, compounded by sudden-onset events/disasters including; drought, rainstorms, flooding and landslides, that threaten livelihood security and trigger voluntary and forced migrations. Migration also occurs as a coping strategy to environment and climate shocks and stresses. However, empirical research evidence on the numbers of people who have migrated because of environmental change or climate change is still lacking as more research focus has been on the socio-economic and political drivers of migration. Deeper empirical research that incorporates spatial analyses on how the environmental and climate parameters induce migrations is necessary to provide an evidence base to inform transformative policy processes and actions that address human mobility challenges and build resilient societies in Uganda.

Climate change has severe and pervasive impacts on natural systems and affects many aspects of human life. Increasing temperatures and alterations in the regimes of precipitations are adding pressure to global agricultural systems, which are already struggling to respond to expanding global demand for food. This directly translates into additional risks for poor people living in developing countries who already face precarious food security conditions. Focusing on the case of Uganda and using household data from the National Panel Survey merged with climatic data from the US National Oceanic and Atmospheric Administration, this paper explores the link between climate change and households' food insecurity. By applying a generalized ordered logit model, this work provides quantitative evidence about the impact of climate variability on food and nutrition security of clustered food consumption groups of smallholder farmers. Among the different socio-economic and environmental variables affecting the households' food security conditions, time and cross-sectional variations in the regime of precipitations play a crucial role. The results highlight that adaptation programmes aimed to reduce climate-induced food insecurity and improve coping abilities of rural communities should be site-specific and involve local communities with the aim of considering the specific risk exposure of the different agro-ecological areas.

- Abstract
Palms are highly significant tropical plants. Oil palms produce palm oil, the basic commodity of a highly important industry. Climate change from greenhouse gasses is likely to decrease the ability of palms to survive, irrespective of them providing ecosystem services to communities. Little information about species survival in tropical regions under climate change is available and data on species migration under climate change is important. Palms are particularly significant in Africa: a palm oil industry already exists with Nigeria being the largest producer. Previous work using CLIMEX modelling indicated that Africa will have reduced suitable climate for oil palm in Africa. The current paper employs this modelling to assess how suitable climate for growing oil palm changed in Africa from current time to 2100. An increasing trend in suitable climate from west to east was observed indicating that refuges could be obtained along the African tropical belt. Most countries had reduced suitable climates but others had increased, with Uganda being particularly high. There may be a case for developing future oil palm plantations towards the east of Africa. The information may be usefully applied to other palms. However, it is crucial that any developments will fully adhere to environmental regulations. Future climate change will have severe consequences to oil palm cultivation but there may be scope for eastwards mitigation in Africa.

El Niño/southern oscillation (ENSO) activity is known to affect weather patterns in many parts of the world. This paper develops an approach to identifying signals and incorporating associated impacts on hydrological risk into water resources planning and management. The paper builds on earlier research reported in the climatology literature, and brings this to the engineering domain. An evaluation of seasonal rainfall in Guyana clearly demonstrates that distinct rainfall distributions are associated with La Niña and El Niño events. Forecasts of these events are made by a number of organisations at lead times of up to eight months. If these are coupled with the precipitation analysis presented in this paper, an objective hydrological risk assessment can be made. The methodology applied in Guyana has been repeated with data on net basin supply to Lake Victoria. There is a clear indication of a link between ENSO activity and net basin supply to Lake Victoria.

Maize crop (Zea mays) is one of the staple foods in the East African (EA) region. However, the suitability of its production area is threatened by projected climate change. The Multimodel Ensemble (MME) from eight Coupled Model Intercomparison Project 5 (CMIP5) models was used in this paper to show climate change between the recent past (1970–2000) and the future (2041–2060), i.e., the mid-twenty-first century. The climatic suitability of maize crop production areas is evaluated based on these climate datasets and the current maize crop presence points using Maximum entropy models (MaxEnt). The MME projection showed a slight increase in precipitation under both RCP4.5 and RCP8.5 in certain places and a reduction in most of southern Tanzania. The temperature projection showed that the minimum temperature would increase by 0.3 to 2.95 °C and 0.3 to 3.2 °C under RCP4.5 and 8.5, respectively. Moreover, the maximum temperature would increase by 1.0 to 3.0 °C and 1.2 to 3.6 °C under RCP4.5 and 8.5 respectively. The impacts of these projected changes in climate on maize production areas are the reduction in the suitability of the crop, especially around central and western Tanzania, mid-northern and western Uganda, and parts of western Kenya by 20–40%, and patches of EA will experience a reduction of as high as 40–60%, especially in northern Uganda, and western Kenya. The projected changes in temperature and precipitation present a significant negative change in maize crop suitability. Thus, food security and the efforts towards the elimination of hunger in EA by the mid-twenty-first century will be hampered significantly. We recommend crop diversification to suit the new future environments, modernizing maize farming programs through the adoption of new technologies including irrigation, and climate-smart agricultural practices, etc. [ABSTRACT FROM AUTHOR]

The entire agricultural supply chain, from crop production to food consumption, is expected to suffer significant damages from climate change. This paper empirically investigates the effects of warming on agricultural labor supply through variation in dietary intake in rural Uganda. We examine labor supply, food consumption, and overall social welfare under various climate change scenarios. First, we combine nationally representative longitudinal survey data with high-resolution climatic data using an instrumental variable approach. Controlling for calorie intake, our study shows that warming has a non-linear impact on agricultural labor supply, with the number of hours worked being optimized at an optimal temperature of 21.3°C. Using these econometric estimates to parametrize an overlapping generations model, we find that under RCP8.5, output per adult decreases by 20 per cent by the end of the century due to the combined effect of climate change on food consumption and labor supply.

Climate change affects both men and women which, in turn, shapes their varied and contrasting perceptions of climate variability and change. This paper examined the gendered perceptions of climate variability and change among local communities in Queen Elizabeth National Park in Uganda. The objectives are threefold: - identify climatic shocks faced by the local communities; examine the perceptions of men and women of climate variability and change; and to compare their perceptions with empirical meteorological data. This study employed both qualitative and quantitative methods, with data collected from 215 respondents using survey, interviews and focused group discussions. From the findings, indicators of climate variability and change included reduced flooding events, occurrence of human diseases, increasing crop pests and diseases, dry spells and intensity of rains. There was increasing significant temperatures while rainfall was declining. Both male and female significantly associated with increasing temperatures and reduced flooding events. While climatic shocks affected both males and females, the impact was more pronounced depending on distinct livelihood activities and roles and responsibilities undertaken. The study concluded that people’s perceptions of climate change should be taken on by the government and integrated in the national climate programs that support people’s livelihoods and survival mechanisms.

This paper proposes a shift from the concept of disaster to one of devastation when dealing with the destructive consequences of climate change. It argues that today, a discourse of climate‐change disaster has become dominant, in which present disasters are seen as harbingers of a future of widespread climate disaster, products of a global nature in upheaval. The paper contends that one needs to go beyond the series of dichotomies that the climate‐change disaster discourse relies upon: future/past, global/local, natural/social. To frame climate disaster as a product of global climate change, and conflict the product of those climate disasters, is to occlude the forms of environmental violence and experience of climate change among disaster‐affected communities. Through an exploration of the drought in Uganda, the paper asserts that disaster should be understood as embedded within ongoing, longstanding, multiscalar processes of devastation produced by histories of human engagement with the environment, including that of war.

The global dimensions of climate change necessitate a response that takes national differences – social, economic, geographic, and cultural – into account. Action-oriented education has a key role to play in advancing citizen engagement in a culture of sustainability. This paper describes research conducted with one such education programme, Youth Leading Environmental Change (YLEC), which operates in six countries and engages university-aged youth in discussion and practice related to global sustainability, systems thinking, and environmental justice. YLEC aims to advance four key competencies; this paper focuses on the goal of action competence, which involves acquiring knowledge, reflecting on experience in the context of one’s values, envisioning alternative futures, and acting individually and collectively to advance those alternatives. The present article examines the impacts of YLEC on environmental action competence in two of the countries involved in this research: Uganda and Germany. In-depth interviews were conducted with participants in both countries to examine the development of action competence during and after the programme. Findings suggest that outcomes differed in each country, reflective of participants’ different lived experiences. YLEC effectively built on the conditions faced in each country to accompany youth to a higher level of awareness and action. These findings have implications for environmental education programmes striving to work with multiple nations and diverse participants. [ABSTRACT FROM PUBLISHER]

This paper identifies the business constraints that are most binding for firm performance. Using panel methods on novel quarterly Ugandan business climate data, we exploit perceived changes in business climate constraints to account for changes in firm performance. Not all identified constraints are binding for firm performance. Macroeconomic instability, demand stability, access to finance, corruption/bribery, and weather variability are found to be binding constraints. Firms' expectations about future performance outcomes are associated with current perceptions about these constraints, alleviating endogeneity concerns to some extent. While taxation constraints are usually highly ranked, we do not find evidence linking them to firm performance. [ABSTRACT FROM AUTHOR]

Developing countries in tropical and subtropical areas will be the worst hit by climate change. Very little research has been done to assess the impact of climate change on thermal comfort in low-income housing in these regions. The effects of solar shading strategies and solar absorptance properties of walls and roofs on thermal comfort in Ugandan low-income housing are studied in this paper. Various shading strategies including curtains, roof and window overhangs, veranda and trees as well as effects of painting on solar heat gain and thermal comfort are modelled using EnergyPlus software. An adaptive approach for naturally ventilated buildings defined by the European Committee for Standardization standard BS EN 15251:2007 is used to assess the conditions. According to the results, solar shading is less effective in meeting thermal comfort requirements and it should be used in conjunction with other strategies to achieve desirable results. White painting, in contrast, significantly improved the conditions and significantly reduced the risk of overheating. Solar shading proved to be effective during the hottest periods of the year, reducing the risk of extreme overheating by up to 52%. [ABSTRACT FROM AUTHOR]

Many of the people who are most vulnerable to the effects of climate change live in low-income and informal settlements in and around urban centres in Africa, Asia and Latin America. While there is a growing recognition of the importance of urban resilience, there is little documented evidence of how collective actions undertaken by residents of these communities can contribute to this. This paper describes the processes adopted by the National Slum Dwellers Federation of Uganda for responding to a variety of challenges – and explains how these not only address the immediate needs of these communities but also contribute to building resilience at the scale of the individual, household, community and city. It links the experiences of manufacturing matoke briquettes, developing new construction materials for low-income housing, and improving drainage and freshwater supplies to some of the key features of an urban resilience agenda, and makes the case for broader international support and funding to these local responses to climate change.

This paper models the retrofitting of traditional rural dwellings in Uganda by introducing passive cooling and daylighting measures. With climate change, outdoor temperatures in parts of the Global South will become unbearable. Communities will be forced to spend more time indoors and thus require further cooling and daytime lighting for thermal and visual comfort. Passive measures can address this while also attenuating energy consumption and diversifying energy use. For the first time, these measures are combined and modelled for those purposes in a rural developing country context where there is limited access to electricity. Using SketchUp and EnergyPlus™, we simulate 15 scenarios of passive cooling and daylighting measures for two baseline scenarios: electrified mud hut and semi-permanent dwelling. Those are also feasible scenarios for similar greenfield unelectrified architectures. The results from the simulated scenarios on electrified dwellings include energy savings, and from these, payback periods are calculated. Two cost-effective scenarios are identified. For mud huts, combining shading (through vegetation) with a centralised fibre optic solar concentrator enables an annual reduction of 31 % of energy consumption. For semi-permanent dwellings, painting rooftops white combined with the integration of solar water light bulbs reduces energy consumption by 47 %. In terms of payback periods for the selected scenarios, the former is four years and nine months, while the latter is two months. • Modelling of passive cooling and daylighting measures in North Ugandan dwellings • Design of mud hut and semi-permanent structures based on field surveys • Extensive presentation of rationale of selection for passive measures • Combination of passive measures into scenarios for energy performance evaluation • Assessment of energy savings, costs and scenarios payback periods [ABSTRACT FROM AUTHOR]

WATER harvesting ,CLIMATE change ,RAINFALL reliability ,GENERAL circulation model - Abstract
This paper assesses the effect of climate change on reliability of rainwater harvesting systems for Kabarole district, Uganda, as predicted by 6 best performing global circulation models (GCMs). A daily water balance model was used to simulate the performance of a rainwater harvesting system using historical daily rainfall data for 20 years. The GCMs used to generate daily rainfall projections for 2025–2055 and 2060–2090 periods included; ACCESS1-0, BCC-CSM-1-M, CNRM-CM5, HADGEM2-CC, HADGEM2-ES and MIROC5. Analysis was based on the Ugandan weather seasons which included March, April, May (MAM) and September, October, November (SON) rain seasons in addition to December, January, February (DJF) and June, July, August (JJA) dry seasons. While an increase in reliability is predicted for the SON season, the worst-case scenario is projected during the MAM season with a reliability reduction of over 40% for the 2055–2090 period. This corresponds to a 27% reduction in water security for the same period. The DJF season is also expected to experience reduced water security by 1–8% for 2025–2055 and 2060–2090 with a 0.5 m
3 tank size. Therefore, some form of extra harvesting surface and increased tank size will be required to maintain 80% systems reliability considering climate change. [ABSTRACT FROM AUTHOR]- Published

Sustainable management of land and its ecosystem requires welldocumented Land-use and Land Cover changes (LULCCs) that have occurred over time. The objective of this study was to document the LULCCs, determine their relationship with climate and population changes in Western Uganda, and provide evidence to support decision-making in this region. This study utilized satellite images for the years 1992, 2000, 2010, and 2020 obtained from the European Space Agency Climate Change Initiative (ESA CCI), climatic data from NASA, and population data from the Uganda Bureau of Statistics (UBoS). LULCCs and their influencers were characterized in the region, for the period 1992 to 2020. ArcGIS Pro Software Program was used to Filter time series data using Definition Query, while the scatterplot was employed to determine the relationship between changes in climate and population on LULCCs. Results indicate that LULC is dominated by agriculture (66.46%), followed by forests (16.22%), waterbodies (8.0%), grassland, shrubland, wetland, and urban areas at 6.11%, 2.63%, 0.49%, and 0.1%, respectively. From 1992 to 2020, the area under agriculture, forest and urban increased by 0.1%, 0.1%, and 0.08%, respectively, while grassland, wetland, and shrubland declined by 0.22%, 0.05%, and 0.01%, respectively. LULCCs for areas under wetland, grassland, and urban areas have a stronger relationship with precipitation and population growth. This information can be used by the decision-makers at the local, district, and national levels to better guide land-use practices aimed at sustainable land-use management for the current and future generations.

The West Nile region in northwestern Uganda is a focal point for human plague, which peaks in boreal autumn and is spread by fleas that travel on rodent hosts. The U.S. Centers for Disease Control and Prevention is collaborating with the National Center for Atmospheric Research to quantitatively address the linkages between climate and human plague in this region. The aim of this paper is to advance knowledge of the climatic conditions required to maintain enzootic cycles and to trigger epizootic cycles and ultimately to target limited surveillance, prevention, and control resources. A hybrid dynamical-statistical downscaling technique was applied to simulations from the Weather Research and Forecasting Model (WRF) to generate a multiyear 2-km climate dataset for modeling plague in the West Nile region. The resulting dataset resolves the spatial variability and annual cycle of temperature, humidity, and rainfall in West Nile relative to satellite-based and in situ records. Topography exerts a first-order influence on the climatic gradients in West Nile, which lies in a transition zone between the drier East African Plateau and the wetter Congo Basin, and between the unimodal rainfall regimes of the Sahel and the bimodal rainfall regimes characteristic of equatorial East Africa. The results of a companion paper in which the WRF-based climate fields were applied to develop an improved logistic regression model of human plague occurrence in West Nile are summarized, revealing robust positive associations with rainfall at the tails of the rainy season and negative associations with rainfall during a dry spell each summer.

This paper investigates farmers’ perceptions of climate change and variability in southwest Uganda and compares them with daily rainfall and temperature measurements from the 1960s to the present, including trends in daily rainfall and temperature, seasonality, changing probability of risk and intensity of rainfall events. Statistical analyses and modelling of rainfall and temperature were performed and contrasted with qualitative data collected through a semi-structured questionnaire. The fieldwork showed that farmers perceived regional climate to have changed in the past 20 years. In particular, farmers felt that temperature had increased and seasonality and variability had changed, with the first rainy season between March and May becoming more variable. Farmers reported detailed accounts of climate characteristics during specific years, with recent droughts in the late 1990s and late 2000s confirming local perceptions that there has been a shift in climate towards more variable conditions that are less favourable to production. There is a clear signal that temperature has been increasing in the climate data and, to a lesser extent, evidence that the reliability of rains in the first season has decreased slightly. However, rainfall measurements do not show a downward trend in rainfall amount, a significant shift in the intensity of rainfall events or in the start and end of the rainy seasons. We explore why there are some differences between farmers’ perceptions and the climate data due to different associations of risk between ideal rainfall by farmers, including the amount and distribution needed for production, meteorological definitions of normal rainfall or the long-term statistical mean and its variation, and the impact of higher temperatures. The paper reflects on the methodological approach and considers the implications for communicating information about risk to users in order to support agricultural innovation.

The increasing frequency of negative rainfall shocks presents households with the challenging choice of whether to send their children to school or to withdraw them in order for them to provide support in the household. We use high-resolution spatial rainfall data matched with the georeferenced Uganda National Panel Survey data to estimate the effect of negative rainfall shocks on children's school attendance. We find that exposure to negative rainfall shocks significantly reduces children's school attendance by almost 10%. These results have important policy implications for improving children's schooling, particularly in geographical areas that receive particularly erratic rainfalls, in Uganda. [ABSTRACT FROM AUTHOR]

This becomes harder in a transboundary setting where a basin is shared by different countries in a region that is 60% arid and semi-arid areas, such as the Horn of Africa where tensions due to water scarcity are high. Stakeholders in the transboundary settings often represent varied interests, drawn from different sectors and levels from local to national to regional scales in the riparian countries. Hence the need for a benefit-sharing dialogue. [ABSTRACT FROM AUTHOR]

In the present study, information collected from 360 coffee‐cultivating households (HHs) is used to investigate perceptions of deficiencies in three sub‐counties in Eastern Uganda and to study changes in these perceptions between two survey rounds. The results of an explorative principal components analysis identify five factors affecting farmers' perceptions. Whereas perceptions of deficiencies in the preconditions for farm management activities differ significantly between the three sub‐counties investigated, indicators of deficiencies in general life quality are distributed more equally. Deteriorations are explained mainly by perceived changes in weather conditions. On the one hand, it can be assumed that the high constraint level will continue to increase in the future due to climate change and its impacts on life quality and the basic conditions required for farm management. On the other hand, access to resources such as water taps but also increased competition between buyers, have improved the situation. Results further indicate that if activities such as the expansion of information access and improvement of road conditions (after land registration) are implemented on a larger scale, these negative trends can be partly counteracted to help farmers maintain the conditions for effective farm management and improve their quality of life in the future.

Vulnerability to the health impacts of climate change will be shaped by the existing burden of ill- health and is expected to be highest in poor and socio-economically marginalized populations. Sub-Saharan Africa, in particular, is considered a highly vulnerable region. This paper analyses the vulnerability and adaptive capacity of rural Bakiga communities in southwestern Uganda to climate-sensitive health risks. The objectives were threefold: i) identify key climate-sensitive, community-identified health priorities; ii) describe and characterize determinants of sensitivity to these health priorities at the individual, community and regional levels; and iii) assess the adaptive capacity of Bakiga. Data collection employed a combination of individual and key informant interviews, biographies, future storylines, and Photovoice. Three key health risks were identified by the study communities (malaria, food insecurity, and gastrointestinal illnesses) - all affected by local climatic and environmental conditions, livelihoods, land use changes, and socio-economic conditions. Adaptation within these communities is dependent on their capacity to reduce sensitivities to identified health challenges among the potential of increasing exposures. Crop diversification, reducing deforestation, expanding of livestock rearing, transfer of traditional knowledge, and access to affordable health services are among potential strategies identified. We demonstrate significant existing vulnerabilities to present day climate-related health risks and highlight the importance of non-climatic processes and local conditions in creating sensitivity to health risks. Our place-based understanding is useful to inform interventions or policies aimed to reduce exposure and sensitivity and support adaptive capacity as the conditions these communities face are consistent with many other sub-Saharan African countries.

Adaptive governance is the use of novel approaches within policy to support experimentation and learning. Social learning reflects the engagement of interdependent stakeholders within this learning. Much attention has focused on these concepts as a solution for resilience in governing institutions in an uncertain climate; resilience representing the ability of a system to absorb shock and to retain its function and form through reorganisation. However, there are still many questions to how these concepts enable resilience, particularly in vulnerable, developing contexts. A case study from Uganda presents how these concepts promote resilient livelihood outcomes among rural subsistence farmers within a decentralised governing framework. This approach has the potential to highlight the dynamics and characteristics of a governance system which may manage change. The paper draws from the enabling characteristics of adaptive governance, including lower scale dynamics of bonding and bridging ties and strong leadership. Central to these processes were learning platforms promoting knowledge transfer leading to improved self-efficacy, innovation and livelihood skills. However even though aspects of adaptive governance were identified as contributing to resilience in livelihoods, some barriers were identified. Reflexivity and multi-stakeholder collaboration were evident in governing institutions; however, limited self-organisation and vertical communication demonstrated few opportunities for shifts in governance, which was severely challenged by inequity, politicisation and elite capture. The paper concludes by outlining implications for climate adaptation policy through promoting the importance of mainstreaming adaptation alongside existing policy trajectories; highlighting the significance of collaborative spaces for stakeholders and the tackling of inequality and corruption.

Climate change and variability presents a challenge for rural communities in developing countries. Bridging organizations help align stakeholder and local perspectives and mediate communication that shapes adaptation responses. We argue that a first step for adaptation projects is to determine the nature of the climate norms and how climate is changing. This paper explores the degree to which development organizations in Kenya, Uganda and Tanzania used analysis of local historical climate information in project aims, planning and design. This included 67 participants, managing 102 community-level climate-related agricultural projects, and three NGO case studies. Most focused on low-regret options. The majority of projects enhanced awareness of climate change and variability, but only 7% had used historical climate information during planning. Instead, projects relied on general knowledge or farmers' perceptions, which sometimes differ from analyzed historical climate information, potentially leading reinforcement of perceptions. It is vital that bridging organizations and policy makers value analyzed historical climate information when determining climate norms (including variability) and identify what data shows regarding how climate is changing. This is essential for planning with stakeholders the suitability of alternative crops and cultivars and ensuring other relevant environmental factors influencing agricultural production are considered.

- Abstract
The potential impacts of climate change on human health in sub-Saharan Africa are wide-ranging, complex, and largely adverse. The region's Indigenous peoples are considered to be at heightened risk given their relatively poor health outcomes, marginal social status, and resource-based livelihoods; however, little attention has been given to these most vulnerable of the vulnerable. This paper contributes to addressing this gap by taking a bottom-up approach to assessing health vulnerabilities to climate change in two Batwa Pygmy communities in rural Uganda. Rapid Rural Appraisal and PhotoVoice field methods complemented by qualitative data analysis were used to identify key climate-sensitive, community-identified health outcomes, describe determinants of sensitivity at multiple scales, and characterize adaptive capacity of Batwa health systems. The findings stress the importance of human drivers of vulnerability and adaptive capacity and the need to address social determinants of health in order to reduce the potential disease burden of climate change., (Copyright © 2012 Elsevier Ltd.

Climate change impacts threaten sustainable development efforts. The magnitude of the impacts, however, varies with the socio-ecological characteristics of locations. This is the reason there is consensus on the necessity for climate change adaptive capacity building that is country driven, and based on, and responsive to, local needs. However, information on context specific capacity building needs in developing countries is not readily available. The objective of this study was to establish location specific awareness, training, educational research and technology capacity building needs for climate change adaptation among smallholder farmers in Uganda. Semi-structured questionnaires were used with 465 households from five agro-ecological zones, selected based on the level of vulnerability of agricultural systems to the main climate variation and change hazards. Results reveal substantial capacity building needs in all the zones. The majority of the farmers needed capacity building for interventions on soil-water conservation practices for adapting to drought and unpredictable rainfall. For all zones, education, research, and technology were perceived as key needs. However, the needs varied among zones. These results demonstrate the importance of context specificity in adaptation efforts. The study provides agro-ecological and social system specific information for climate change adaptation planning and policy interventions for effective capacity building. [ABSTRACT FROM AUTHOR]

Highlights • REDD+ activities are fairly recognized in Uganda's policies and laws. • Local government Act is not comprehensive for the implementation of sub-national REDD+ projects. • The policies are skewed mostly towards direct drivers of deforestation and forest degradation. • The laws of Uganda mainly provide for reducing deforestation and conservation of forest stocks. • The Agriculture policy is silent on all the REDD+ activities. Abstract A supportive policy and legal framework is critical for the implementation of interventions to mitigate climate change such as REDD+. This paper analyses Uganda's policies and laws, with the purpose of determining whether the policy issue, objectives of policies and laws provide for a supportive environment for REDD+ activities. The policies and laws analyzed include those indicated in Uganda's Readiness preparedness proposal and any other relevant public policies. The following questions guided the analysis: Are the REDD+ activities as prescribed in proceedings of the 16
th COP to UNFCCC recognized in the policy issue and characterized? Are the REDD+ activities reflected in the object and subsequent provisions of the laws reviewed? From the analysis, it was found that deforestation and forest degradation, loss of protected areas, failure to sustainably utilize natural forests, and limited implementation of forest enhancement activities are recognized as a policy issue in some but not all policies. The characterization of deforestation and forest degradation is mostly linked to proximate drivers while barriers to conservation of forest carbon stocks, sustainable management of forests and enhancement of forest carbon stocks is linked to underlying drivers. Reducing deforestation and forest degradation are the most provided for activities in the policy issue and characterization, while enhancement of forest carbon stocks and sustainable management of forests are the least considered. Reducing forest degradation and conservation of forest stocks are the most provided for in the object and subsequent provisions of the Laws, while enhancement of forest carbon stocks is the least. Conservation of forest carbon stocks and reducing forest degradation are reflected in both policy issue and laws. The current policy and legal framework is suitable mainly for addressing the drivers of deforestation and forest degradation as well as addressing the barriers to conservation of forest stocks.

This paper examines the legal and policy barriers to the Clean Development Mechanism (CDM) implementation in Uganda. Although CDM has been perceived as an opportunity through which developing countries can achieve sustainable development while at the same time helping to mitigate climate change, it remains unclear as to whether CDM will in fact deliver the much anticipated sustainable development benefits in light of the current global trends in CDM investments. By February 2007, only approximately 1.5% of the total registered projects were in Africa and one project was in Uganda. The main study methodology has been library research. [ABSTRACT FROM AUTHOR]

Smoky cookfires contribute to global climate change and kill approximately four million people annually. While many studies have examined the effects of fuel-efficient cookstoves, this study does so while selling stoves at market prices. After introducing a fuel-efficient cookstove, fuelwood use and household air particu-lates declined by 12% and by smaller percentages after adjusting for observer-induced bias, or the Hawthorne effect. These reductions were less than laboratory predictions and fell well short of World Health Organization pollution targets. Even when introducing a second stove, most households continued to use their traditional stoves for most cooking. Future research should focus on improving the usability of fuel-efficient cookstoves and/or policies that assist consumers to shift to safer fuels like gas or electricity coupled with mechanisms to disable the existing smoky cookfire.

This study was motivated by the high reliance on hydropower plants (HPPs) developed and planned along the river Nile and the fact that drought events are the most imminent and drastic threats to Uganda's power production. The study aimed to assess HPPs' resilience and the effectiveness of selected adaptation measures. The climate, land, energy, and water system (CLEWs) framework was employed to assess resilience amidst competing water demands and stringent environmental flow requirements. Under extreme dry conditions, power generation could plummet by 91% over the next 40 years, which translates into an annual per capita consumption of 19 kWh, barely sufficient to sustain a decent socioeconomic livelihood. During arid conditions, climate models predicted an increase in streamflow with increasing radiative forcing. Restricting the ecological flow to 150 m
3 /s could improve generation by 207%. In addition, if planned power plants were to be built 5 years ahead of schedule, the normalized mean annual plant production could increase by 23%. In contrast, increasing reservoir volumes for planned power plants will have no significant impact on generation. The path to HPP resilience could entail a combination of diversifying the generation mix, installing generators with varying capacities, and incorporating adjustable orifices on reservoirs.

• Women face unique risks associated with food insecurity and climate change. • Changing childbearing may be an explicit livelihood strategy. • Women respond to growing season conditions by adjusting fertility behaviors. • Ensuring availability of diverse family planning services is a priority. Agricultural production and household food security are hypothesized to play a critical role connecting climate change to downstream effects on women's health, especially in communities dependent on rainfed agriculture. Seasonal variability in agriculture strains food and income resources and makes it a challenging time for households to manage a pregnancy or afford a new child. Yet, there are few direct assessments of the role locally varying agricultural quality plays on women's health, especially reproductive health. In this paper we build on and integrate ideas from past studies focused on climate change and growing season quality in low-income countries with those on reproductive health to examine how variation in local seasonal agricultural quality relates to childbearing goals and family planning use in three countries in sub-Saharan Africa: Burkina Faso, Kenya, and Uganda. We use rich, spatially referenced data from the Performance Monitoring for Action (PMA) individual surveys with detailed information on childbearing preferences and family planning decisions. Building on recent advances in remote monitoring of seasonal agriculture, we construct multiple vegetation measures capturing different dimensions of growing season conditions across varying time frames. Results for the Kenya sample indicate that if the recent growing season is better a woman is more likely to want a child in the future. In Uganda, when the growing season conditions are better, women prefer to shorten the time until their next birth and are also more likely to discontinue using family planning. Additional analyses reveal the importance of education and birth spacing in moderating these findings. Overall, our findings suggest that, in some settings, women strategically respond to growing season conditions by adjusting fertility aspirations or family planning use. This study also highlights the importance of operationalizing agriculture in nuanced ways that align with women's lives to better understand how women are impacted by and respond to seasonal climate conditions.

Payments for ecosystem services (PES) are increasingly being implemented worldwide as conservation instruments that provide conditional economic incentives to landowners for a prespecified duration. However, in the psychological and economic literature, critics have raised concerns that PES can undermine the recipient's intrinsic motivation to engage in pro-environmental behavior. Such "crowding out" may reduce the effectiveness of PES and may even worsen conservation outcomes once programs are terminated. In this study, we harnessed a randomized controlled trial that provided PES to land users in Western Uganda and evaluated whether these incentives had a persistent effect on pro-environmental behavior and its underlying behavioral drivers 6 y after the last payments were made. We elicited pro-environmental behavior with an incentivized, experimental measure that consisted of a choice for respondents between more and less environmentally friendly tree seedlings. In addition to this main outcome, survey-based measures for underlying behavioral drivers captured self-efficacy beliefs, intrinsic motivation, and perceived forest benefits. Overall, we found no indications that PES led to the crowding out of pro-environmental behavior. That is, respondents from the treatment villages were as likely as respondents from the control villages to choose environmentally friendly tree seedlings. We also found no systematic differences between these two groups in their underlying behavioral drivers, and nor did we find evidence for crowding effects when focusing on self-reported tree planting behavior as an alternative outcome measure.

World‐wide declines in arthropod abundance and diversity are a major concern, particularly given their importance in ecosystem functioning. Yet, data documenting long‐term trends are rare from the tropics, particularly the Afrotropics. Here we evaluate changes in the arthropod communities in Kibale National Park, Uganda across almost four decades. Systematic sweep‐net sampling was conducted in two forested sections of the park that had been logged and in one old‐growth forest area over 12 consecutive months in 1983/1984 and 2020/2021. This data was augmented with intermittent samples taken in 1986 and 1995. Arthropod abundance declined in all areas, but only significantly so in the moderately logged forestry compartment (41%). Permutational multivariate analysis of variance indicated that community compositions of arthropods differed between the censuses. Understanding the drivers of changes in the arthropod communities is difficult as the system is complex and dynamic. We document an increase in temperature, but no change in rainfall, increases in 11 mammal species, including a marked increase in elephant numbers, and changes in forest structure. We also report on changes in the landscape outside of the park, which includes the human population increasing by a factor of four and agricultural intensification that now includes the use of pesticides. We document that many components of the ecosystem we studied changed simultaneously, which signals that for effective conservation planning, more long‐term multi‐disciplinary efforts are needed.

Inland fisheries support the livelihoods of millions of people in riparian communities worldwide but are influenced by increasing climate variability and change. Freshwater fishing societies are among the most vulnerable to climate change given their dependence on highly threatened aquatic resources. As climate change intensifies, building adaptive capacity within communities and understanding the efficacy of adaptive strategies for maintaining household stability is essential for coping with ongoing social and environmental change.In this study, we examined household perceptions of climate change, livelihood impacts and responses to socio‐ecological changes in fishing‐dependent households in the Lake Victoria basin in Uganda, East Africa. Through a series of household surveys and focus group discussions in five fish landing sites, we assessed social adaptive capacity (SAC) based on 207 households and identified adaptive strategies that are effective for coping with climatic change.We found that people in fishing households are aware of environmental change but that most households do not have adaptive strategies that are efficacious for securing long‐term income and food security.We also investigated household demographics that contribute to SAC, examined links between SAC and adaptive efficacy and established potential routes towards developing effective adaptive approaches in small‐scale fisheries.This work contributes to a growing foundation of documented community‐based knowledge for building adaptive capacity in inland fisheries and the communities around the world that depend on them.

With increasing incidences of the negative impacts of climate change to smallholder farming, an understanding of the effects of farmers' adaptation options to climate change on crop yield is critical in designing practical measures and policies for increasing food production and food security. This study assessed the effects of smallholder farmers climate change adaptation intensity on crop yield with focus on maize, groundnuts and beans in Apac and Amuru districts, northern Uganda. Cross-sectional survey design was employed for data collection. Data were analysed using both descriptive and econometric approaches. Results showed that the most common climate change adaptation strategies used by smallholders related to varietal adjustments including planting different crop varieties each time, drought-resistant varieties, early maturing varieties, improved seeds and changing the time of planting. Yield comparisons between adapters and non-adapters for the three major crops showed that adapters realized significantly higher yields than non-adapters for most of the climate change adaptation strategies. This study suggests that farmers who used more adaptation strategies realized higher yields than the non-adapters. Our findings call for increased efforts by stakeholders to strengthen agricultural extension services and coverage to enhance smallholder farmers capacity to adapt to the effects of climate change.

This paper uses the system of economic and environmental accounting for water to demonstrate how the water sector interacts with the social-economic sectors of the economy. Furthermore, it reviews the existing institutional and policy framework in Uganda, and proposes an analytical framework which can be used to provide sound intersectoral planning in order to achieve sustainable water resource use. The proposed framework also articulates how outcomes of water policies and social-economic policies can be analyzed. In Uganda, the uneven distribution of water resources both in space and time, poses constraints to economic activity particularly in the water-scarce regions of the country. The problem is being exacerbated by the increasingly erratic rainfall and rising temperatures. The accounting results show that the current level of water use within the economy is less than the available quantity. In this regard, there is room for the development of mechanisms to increase its utilization. This would serve to mitigate the scarcity especially of water for production which primarily emanates from climate variability. This in turn affects the performance of the economy, as key sectors such as agriculture are rainfall-dependent. [ABSTRACT FROM AUTHOR]

The assessment of population vulnerability under climate change is crucial for planning conservation as well as for ensuring food security. Coffea canephora is, in its native habitat, an understorey tree that is mainly distributed in the lowland rainforests of tropical Africa. Also known as Robusta, its commercial value constitutes a significant revenue for many human populations in tropical countries. Comparing ecological and genomic vulnerabilities within the species' native range can provide valuable insights about habitat loss and the species' adaptive potential, allowing to identify genotypes that may act as a resource for varietal improvement. By applying species distribution models, we assessed ecological vulnerability as the decrease in climatic suitability under future climatic conditions from 492 occurrences. We then quantified genomic vulnerability (or risk of maladaptation) as the allelic composition change required to keep pace with predicted climate change. Genomic vulnerability was estimated from genomic environmental correlations throughout the native range. Suitable habitat was predicted to diminish to half its size by 2050, with populations near coastlines and around the Congo River being the most vulnerable. Whole‐genome sequencing revealed 165 candidate SNPs associated with climatic adaptation in C. canephora, which were located in genes involved in plant response to biotic and abiotic stressors. Genomic vulnerability was higher for populations in West Africa and in the region at the border between DRC and Uganda. Despite an overall low correlation between genomic and ecological vulnerability at broad scale, these two components of vulnerability overlap spatially in ways that may become damaging. Genomic vulnerability was estimated to be 23% higher in populations where habitat will be lost in 2050 compared to regions where habitat will remain suitable. These results highlight how ecological and genomic vulnerabilities are relevant when planning on how to cope with climate change regarding an economically important species. [ABSTRACT FROM AUTHOR]

Abstract: The paper discusses the application of a method to analyze the capacity for management of wetland resources. The method consists of a framework with a set of indicators to analyze the presence and effectiveness of formal regulations and procedures, and relevant informal mechanisms for wetland management. The set of indicators is designed based on internationally recognized objectives and ‘good practices’ for wetland management given in the Ramsar Convention guidelines. The guidelines advise on which policies and authorities should be in place, and which actions should be taken in order to use wetland resources sustainably. Evaluation is seen as ‘measuring’ the closeness between the real wetland management system and recommendations given in the guidelines. In the current study, experts were asked to categorize developed indicators for three cases into three classes (high, medium and low capacity). Analysis of these case studies indicates that overall capacity for wetland management is insufficient in Gemenc floodplain (Hungary) and Ga-Mampa wetland (South Africa), and highly insufficient in Nabajjuzi and Namatala wetlands (Uganda). The capacities in these wetland sites are strongest at the policy level and weakest at local level, where policies are to be implemented. In these locations there is a mix of new formal legislation and procedures, having been put in place recently, and informal instruments and planning/management practices from the past, which are still used by wetland managers and stakeholders. Capacity of the wetland management systems to deal with changes such as climate change appeared to be limited. Thus, all the studied wetland sites require an improved capacity as an integral part of wetland management. It is recommended that the wetland managers select future actions that consider a gradual approach that accounts for their capabilities and local institutions. Such an approach can result in a progressive strengthening of actions over time with the overall objective to bring the wetland degradation to a halt. [Copyright &y& Elsevier]

Over 85% of Uganda's 34 million people depend on rural water supply systems and the current water and environment sector performance report (2017) reports an 84% functionality of rural water sources such as boreholes and shallow wells with a hand pump. Ensuring the continued operation of water points, and in keeping with participatory theory, the water user's committees (WUCs) should also be a vehicle for empowering communities while bringing about greater equity of use. However, WUC members do not acquire the knowledge and skills they need by default but require different types of training. This study sought to evaluate community participation and capacity development in WUCs in relation to community-managed water supply systems. A shared dialogue workshop (SDW), as well as 642 randomly selected households across 17 villages in two Parishes in Lwengo district, southern Uganda were considered. Results indicated that 41.7% of surveyed households used an unprotected source while up to 30% had a member in a WUC. Fifty-two percent of households had never made any financial contributions to a WUC, while 34.6% did so on an ad hoc basis. This paper examines the relationship between participation, mobilization, and financial contributions. The chi-square test indicated mobilization has no impact on household financial contributions to a WUC. However, the majority of even those households that were mobilized made a payment only occasionally, and specifically when the source broke down. Additionally, the test result reveals that there is no difference between better off and relatively poor households in their contributions to a WUC, an indication that other factors influence such decisions. Training activities, especially on the operation and maintenance of water points and to undertake minor repairs, were mostly provided by non-governmental organizations (NGOs)/project staff. Abandoned boreholes, lack of rehabilitation activities, and loss of enthusiasm are all indications that the technical, financial, and institutional performance of community-managed water supply systems needs improvement.

Land use, land cover, and climate change impacts are current global challenges that are affecting many sectors, like agricultural production, socio-economic development, water quality, and causing land fragmentation. In developing countries like Uganda, rural areas with high populations dependent on agriculture are the most affected. The development of sustainable management measures requires proper identification of drivers and impacts on the environment and livelihoods of the affected communities. This study applied drivers, pressure, state, impact, and response model in the L. Kyoga basin to determine the drivers and impacts of land use, land cover, and climate change on livelihoods and the environment. The objective of this study was to determine the drivers and impacts of land use, land cover, and climate changes on the environment and livelihoods in the L. Kyoga basin and suggest sustainable mitigation measures. Focus group discussions, key informant interviews, field observations, and literature reviews were used to collect data. Population increase and climate change were the leading drivers, while agriculture and urbanization were the primary pressures, leading to degraded land, wetlands, and forests; loss of soil fertility, hunger, poverty, poor water quality, which are getting worse. The local communities, government, and non-government institutions had responses to impacts, including agrochemicals, restoration, and conservation approaches. Although most responses were at a small/pilot scale level, most responses had promising results. The application of policies and regulations to manage impacts was also found to be weak. Land use, land cover changes, and climate change occur in the L. Kyoga basin with major impacts on land, water, and community livelihoods. With the observed increase in climate change and population growth, drivers and impacts are potentially getting worse. Therefore, it is essential to expand interventions, provide relief, review policies and regulations, and enforce them. The findings are helpful for decisions and policy-makers to design appropriate management options. [ABSTRACT FROM AUTHOR]

Background: There is concern in the international community regarding the influence of climate change on weather variables and seasonality that, in part, determine the rates of malaria. This study examined the role of sociodemographic variables in modifying the association between temperature and malaria in Kanungu District (Southwest Uganda). Methods: Hospital admissions data from Bwindi Community Hospital were combined with meteorological satellite data from 2011 to 2014. Descriptive statistics were used to describe the distribution of malaria admissions by age, sex, and ethnicity (i.e. Bakiga and Indigenous Batwa). To examine how sociodemographic variables modified the association between temperature and malaria admissions, this study used negative binomial regression stratified by age, sex, and ethnicity, and negative binomial regression models that examined interactions between temperature and age, sex, and ethnicity. Results: Malaria admission incidence was 1.99 times greater among Batwa than Bakiga in hot temperature quartiles compared to cooler temperature quartiles, and that 6–12 year old children had a higher magnitude of association of malaria admissions with temperature compared to the reference category of 0–5 years old (IRR = 2.07 (1.40, 3.07)). Discussion: Results indicate that socio-demographic variables may modify the association between temperature and malaria. In some cases, such as age, the weather-malaria association in sub-populations with the highest incidence of malaria in standard models differed from those most sensitive to temperature as found in these stratified models. Conclusion: The effect modification approach used herein can be used to improve understanding of how changes in weather resulting from climate change might shift social gradients in health.

The study examines the relationship between sudden- and gradual-onset climate events and migration, hypothesizing that this relationship is mediated by the adaptive capacity of affected individuals. We use survey data from regions of Cambodia, Nicaragua, Peru, Uganda, and Vietnam that were affected by both types of events with representative samples of non-migrant residents and referral samples of migrants. Although some patterns are country-specific, the general findings indicate that less educated and lower-income people are less likely to migrate after exposure to sudden-onset climate events compared to their counterparts with higher levels of education and economic resources. These results caution against sweeping predictions that future climate-related events will be accompanied by widespread migration. [ABSTRACT FROM AUTHOR]

Adaptation framing remains one of the major challenges to achieving greater implementation of adaptation initiatives in Sub-Saharan Africa (SSA). Using an integrated analytical framework that frames adaptation indicators into three dimensions; adaptive, absorptive and transformative capacities, we analysed the adaptation diversity in Karamoja sub-region, Uganda. We found a strong perception of the existence of climate variability and change manifested through the occurrence of droughts, floods, hailstorms, late onset and early rainfall onset. Absorptive capacity revealed varied status of asset ownership, custodianships, and access to these assets, presence of informal social safety nets, and social cohesion. Adaptive capacity revealed the presence of a diversity of livelihood sources, livelihood assets and associated income, but its human capital indicator revealed considerably high illiteracy levels among respondents. Meanwhile, transformative capacity revealed existence of network structures, governance and institutions, facilitated access to early warning information on pests, diseases and rainfall onset. Traditional institutions and the justice system played a key role in conflict resolution, mediation and negotiation for kraals establishment, grazing, and watering rights. We conclude that pastoral communities in Karamoja have a high inclination to maintenance of stability while their flexibility and ability to change decreases with the intensity of change pro-rata. Le cadrage de l'adaptation reste l'un des défis majeurs pour parvenir à une plus grande mise en oeuvre des initiatives d'adaptation en Afrique subsaharienne (ASS). En utilisant un cadre analytique intégré qui encadre les indicateurs d'adaptation en trois dimensions; capacités d'adaptation, d'absorption et de transformation, nous avons analysé la diversité de l'adaptation dans la sous-région de Karamoja, en Ouganda. Nous avons trouvé une forte perception de l'existence de la variabilité et des changements climatiques qui se manifestent par la survenue de sécheresses, d'inondations, de tempêtes de grêle, d'apparition tardive et précoce des précipitations. La capacité d'absorption a révélé des statuts variés d' actifs de propriété, de la protection de ses actifs et d'accès à ces actifs, la présence des réseaux de la sécurité sociale informels et la cohésion sociale. La capacité d'adaptation a révélé la présence d'une diversité de sources de subsistance, d'actifs de subsistance et de revenus associés, mais son indicateur de capital humain a révélé des niveaux d'analphabétisme considérablement élevés parmi les répondants. Pendant ce temps, la capacité de la transformation a révélé l'existence de structures de réseau, de gouvernance et d'institutions, a facilité l'accès aux informations d'alerte précoce sur les ravageurs, les maladies et l'apparition des pluies. Les institutions traditionnelles et le système judiciaire ont joué un rôle clé dans la résolution des conflits, la médiation et la négociation pour l'établissement des étables et les droits de pâturage et d'abreuvement. Nous concluons que les communautés pastorales du Karamoja ont une forte tendance au maintien de la stabilité tandis que leur flexibilité et leur capacité à changer diminuent avec l'intensité du changement au prorata.
