The main aim of this paper was to analyze how medicinal gardens in secondary schools can improve teaching-learning processes in rural settings. The sample comprised 179 students (69.3% girls) from a rural public secondary school in the province of Huila (Colombia). The age of the participants ranged from 15 to 17 years with a mean of 15.86 years (SD = 0.86). Seeking school motivation strategies for rural students from a rural institution in the municipality of Guadalupe, teachers of the natural sciences designed didactic-pedagogical alternatives employing situated learning that would allow them to contribute to solving school problems and environmental issues affecting rural areas. The environmental phenomena included the loss of fertile soils and the harmful effects of the use of agrochemicals. Medicinal gardens together with situated learning activities proved a useful teaching tool in formal rural educational settings.

This paper investigates how some small-scale palm oil growers in northeast Colombia have managed to exercise partial autonomy from global markets while still participating in them. By comparing the varied experiences of these farmers, I find that, state-led land access and multiscale organizational support for small-scale farming have enabled these farmers to selectively engage with global markets and carve-out space for autonomous decision-making on their farms. By examining the risks and possibilities associated with farmers' engagement in global value chains, this study illuminates the potential for agricultural transitions and small-scale farming within the context of global agricultural markets.

This paper describes a novel qualitative dataset regarding coffee pests based on the ancestral knowledge of coffee farmers in the Department of Cauca, Colombia. The dataset has been obtained from a survey applied to coffee growers with 432 records and 41 variables collected weekly from September 2020 to August 2021. The qualitative dataset includes climatic conditions, productive activities, external conditions, and coffee bio-aggressors. This dataset allows researchers to find patterns for coffee crop protection through the ancestral knowledge not detected by real-time agricultural sensors. As far as we are concerned, there are no datasets like the one presented in this paper with similar characteristics of qualitative value that express the empirical knowledge of coffee farmers used to detect triggers of causal behaviors of pests and diseases in coffee crops.

The páramos of Boyacá in Colombia are earmarked for delimitation to prevent the expansion of the agricultural frontier and protect endemic flora that contribute to water provision for cities. A varied conservation toolbox will be used, including the creation of protected areas for re-wilding and the 'sustainable' transitioning of livelihoods identified as environmentally destructive. Agriculture and cattle livestock farming has been identified for transitioning. Despite the negative discourse related to livestock holding, this paper argues that small-scale agropastoralism contributes to re-peasantisation and provides the foundations for an agrobiodiverse conservation approach. Agropastoralism facilitates re-peasantisation through strong socio-economic networks, interconnected communities, the solidarity economy, and self-management of natural resources. Whilst, agropastoral mobility spatially binds social networks across large and disconnected spaces. Mobility is also fundamental to dynamic land access and pasture management, as it prevents over-grazing. This exemplifies how resilient socio-economic networks and mobile production strategies could be harnessed for agrobiodiversity, instead of land sparing and other sedentary 'green' economies. This paper makes conceptual contributions to 'autonomy' in re-peasantisation by empirically demonstrating the importance of mobile and flexible systems of production. It also makes a novel methodological contribution in applying a spatial lens that further unpacks how movement across the páramos facilitates autonomy and re-peasantisation. These themes are explored using interview data from 53 semi-structured interviews with key stakeholders and small-scale agropastoralists from across the páramos and field observation. The paper concludes by recommending a harnessing of agropastoral knowledge, to potentiate agrobiodiversity, for a more socio-ecologically just approach to farming and conservation in the páramos.

Returning to Earth's safe operating space requires driving social-ecological transformations toward a new human-nature configuration, while navigating changes and creatively dealing with crises. Family farms in the Colombian Andes have been navigating changes by using modalities of integrated management that recognize family interdependence with nature, which illustrates social-ecological resilience on a small scale. We potentiated family farming by creating FiNCO (Farms for knowledge exchange) as a strategy that renews the connection between disciplines, academia and farmers, and the rural and urban sectors, in order to promote knowledge co-production and landscape stewardship. In this sense, FiNCO is considered as a seed for a good Anthropocene. This paper is an invitation to plant FiNCO seeds in different social-ecological contexts and to share those experiences as an ideal way to create abilities to transform the upcoming humanity challenges into opportunities for humanity's needed transformation., (© 2023.

Agroforestry systems (AFS) upscaling has the potential to integrate sustainability and resilience objectives into agriculture. However, this is a daunting task requiring multi-actor collaboration across public and private sectors at multiple governance levels, coupled with innovative approaches to jointly managing AFS knowledge. Understanding such multi-actor interactions from a network perspective may help to unravel how social structures, created by relational patterns enhance or hinder AFS upscaling. Our paper aims to comparatively explore the role of regional actor-networks on AFS upscaling for a selected farming system. By conducting semi-structured interviews, we collected information about the ties of 86 actors supporting cacao agroforestry systems (CAFS) across two regions of Colombia. We use social network analysis (SNA) to comparatively visualize and understand the general structure of these networks, find relational patterns between the diverse categories of actors involved, and identify a set of key players bridging the majority of the actors within these networks. We find highly centralized networks that connect multiple actors by a low number of mostly non-reciprocal ties. Within these networks, we identify a predominance of bridging ties over bonding ties, homophily patterns among research and education institutions, and heterophily configurations among farmer-based organizations. We also find that the composition of the sets of key actors and the platforms where they converge varies substantially from region to region due to decentralized agricultural policies and differing characteristics across regions. Our approach provides key entry points for promoting multi-actor coalitions that can effectively expand the benefits of AFS in tropical agricultural systems. [ABSTRACT FROM AUTHOR]

Agri-food systems are besieged by malnutrition, yield gaps, and climate vulnerability, but integrated, research-based responses in public policy, agricultural, value chains, and finance are constrained by short-termism and zero sum thinking. As they respond to current and emerging agri-food system challenges, decision makers need new tools that steer toward multi-sector, evidence-based collaboration. To support national agri-food system policy processes, the Integrated Agri-food System Initiative (IASI) methodology was developed and validated through case studies in Mexico and Colombia. This holistic, multi-sector methodology builds on diverse existing data resources and leverages situation analysis, modeled predictions, and scenarios to synchronize public and private action at the national level toward sustainable, equitable, and inclusive agri-food systems. Culminating in collectively agreed strategies and multi-partner tactical plans, the IASI methodology enabled a multi-level systems approach by mobilizing design thinking to foster mindset shifts and stakeholder consensus on sustainable and scalable innovations that respond to real-time dynamics in complex agri-food systems. To build capacity for these types of integrated, context-specific approaches, greater investment is needed in supportive international institutions that function as trusted in-region 'innovation brokers.' This paper calls for a structured global network to advance adaptation and evolution of essential tools like the IASI methodology in support of the One CGIAR mandate and in service of positive agri-food systems transformation., Competing Interests: No competing interests.

Gene editing (GnEd) involves using a site-directed nuclease to introduce a double-strand break (DSB) at a targeted location in the genome. A literature search was performed on the use of GnEd in animals for agricultural applications. Data was extracted from 212 peer-reviewed articles that described the production of at least one living animal employing GnEd technologies for agricultural purposes. The most common GnEd system reported was CRISPR/Cas9, and the most frequent type of edit was the unguided insertion or deletion resulting from the repair of the targeted DSB leading to a knock-out (KO) mutation. Animal groups included in the reviewed papers were ruminants (cattle, sheep, goats, n =63); monogastrics (pigs and rabbits, n =60); avian (chicken, duck, quail, n =17); aquatic (many species, n =65), and insects (honeybee, silkworm, n =7). Yield (32%), followed by reproduction (21%) and disease resistance (17%) were the most commonly targeted traits. Over half of the reviewed papers had Chinese first-authorship. Several countries, including Argentina, Australia, Brazil, Colombia and Japan, have adopted a regulatory policy that considers KO mutations introduced following GnEd DSB repair as akin to natural genetic variation, and therefore treat these GnEd animals analogously to those produced using conventional breeding. This approach has resulted in a non-GMO determination for a small number of GnEd food animal applications, including three species of GnEd KO fast-growing fish, (red sea bream, olive flounder and tiger pufferfish in Japan), KO fish and cattle in Argentina and Brazil, and porcine reproductive and respiratory syndrome (PRRS) virus disease-resistant KO pigs in Colombia. • Gene editing (GnEd) can introduce useful genetic alterations in food animals • A total of 212 papers using GnEd in animals for agriculture were identified • Yield, reproduction, and disease resistance were the most commonly targeted traits • CRISPR/Cas9 was by far the most prevalent GnEd system used to edit animal genomes • Three species of GnEd fast-growing finfish have already been commercialized in Japan [ABSTRACT FROM AUTHOR]

Background: Despite efforts to extend Universal Health Coverage in Colombia, rural and remote populations still face significant challenges in accessing equitable health services. Social innovation has been growing in Colombia as a creative response to the country's social problems including access to healthcare. This paper presents the findings of a social innovation case study, which was implemented in the rural area of Sumapaz in Colombia, with the purpose of holistically addressing the health needs of the local population and enhancing health service access. Methods: A case study methodology was used to investigate and understand the process by which the Model of Integral Health Care for Rural Areas was developed and how the various strategies were defined and implemented. Qualitative methods were used in the data collection and all data was analysed using Farmer et al. staged framework on grassroots social innovation which includes growing the idea; implementing the idea; sustainability and diffusion. Results: The social innovation model was designed as a co-learning process based on community participation. The model was implemented adopting a holistic health approach and considerate of the conditions of a rural context. As a result of this process, access to quality health services were enhanced for the vulnerable rural community. The model has also provided outcomes that transcend health and contribute to individual and community development in different areas eg. agriculture. Conclusion: The Model of Integral Health Care for Rural Areas is a social innovation in health that demonstrates how Universal Health Coverage can be achieved for vulnerable populations through a series of creative strategies which fill systemic voids in access and co-ordination of care, as well as in addresings upstream environmental factors responsible for ill-health.

Violent conflict can accelerate the development of capitalism in rural areas, entailing the transformation of land distribution patterns. However, this transformation via land grabbing in wartime is under-addressed in the literature. This paper explores the case of land dispossession (LD) in Colombia, defined as land grabbing by taking advantage of the armed conflict, a process that affected mainly smallholders and ethnic communities. By conducting a literature review it was found that agrarian elites, networking with public servants and right-wing paramilitary militias, engaged in LD by using violence but also various symbolic devices that justified LD and assisted the legalisation of usurped land. Two main paths of LD are identified, and a typology of symbolic devices used to justify LD is proposed, showing how the armed conflict hastened agrarian capitalism through land accumulation. The opportunistic participation of civilians in the armed conflict setting, the interlaces between symbolic devices and violence, and the role of the state are highlighted as factors fostering a specific path of agrarian change in wartime characterised by the marginalisation of small-scale farming.

Background: The chagra is the agroforestry system adapted to the characteristics of the Amazon region. Recently, there has been a reported loss of biodiversity and traditional knowledge associated with the chagras. This paper characterizes the cultivators, exploring knowledge and expressed value perception in the context of the Amazonian chagra of an indigenous community; also, this prioritizes species, under the optics of commercial opportunity. Methods: A semi-structured instrument was applied to 14 volunteers, asking about marketing preferences and use values of the species; later, a floristic inventory and prioritization workshop was developed. Results: Sixty-two percent of the participants were 50 years or older at the time of the interview. Open conversations showed that traditional knowledge is a matter of practice; and is maintained mainly by the older "grandfathers". Thirty-eight species, belonging to 28 different families, were reported, showing considerable diversity. Seventy-nine percent of the participants consider the Leticia market and sales to tourists as the main marketing scenarios. Conclusions: The Ziora-Amena community centralizes the handling of chagras in the community's older adults, who transmit their traditional knowledge to new generations through oral tradition. Indicators of preference, use, and abundance highlight the food species. The perception of the trade stakeholder encourages research and development of endemic species, with health properties or ingredients for industry, which represent an opportunity of high added value for the region.

New interest in environmental factors in the sociology of agriculture has stimulated the development of a "social ecology" perspective. This paper applies a socioccological perspective to soil resource degradation and the implementation of soil conservation policy in a Calombian farming system. The analysis illustrates two important themes in social ecology: how interaction between biophysical and social parameters in agriculture structures farmers' use of natural resources and the interpretation of natural resources in terms of how farmers perceive them. Analysis of the political economy of the farming system shows how biophysical and institutional factors create incentives for farmers to use destructive soil management practices, which are reflected in norms and values of land use in the farm community, and farm types or adaptive strategies for coping with this environment. The paper concludes that a socioecological perspective focuses analysis on institutional factors that cause soil erosion. [ABSTRACT FROM AUTHOR]

Emerging scholarship on urban land grabbing has urged researchers to take more nuanced perspectives on land appropriation. There is the need to understand the actions of and interactions amongst a multiplicity of local actors—beyond large-scale investors and global cities—when considering land grabs in the spaces of urban development. Therefore, this paper analyses what we conceptualise as the more 'gradual' and 'ordinary' dynamics of land dispossession in the peri-urban spaces of the small-scale city of Sogamoso, Colombia. Based on 38 semi-structured key-informant interviews, we explore everyday actions, actors and power relations involved in urban expansionism, mining, farming and ecosystems conservation as these activities seek to coexist and compete for the same, relatively sparse amount of peri-urban space. We find that land appropriation is facilitated by multi-level policy incoherence and the failures of municipal governance. Policy incoherence results in normative uncertainty and weak environmental governance, while a lack of coordinated municipal governance in peri-urban spaces leads to further small scale, 'ordinary' and therefore 'invisible' conflicts, to the detriment of citizens' livelihoods. This paper contributes to understanding spatially differentiated urban land appropriation, and its articulation with local, gradual, subtle and more hidden land use conflicts, governance regimes and power relations at the scales of the everyday. Our findings suggest the need to theorize urban land grab also as a result of ordinary, place-based, quotidian dynamics that emerge from governance problematics, including policy incoherence, and land use conflicts, and from the intersection of a more diverse set of drivers, mechanisms and actors than discussed in the extant literature with focus on large urban centres.

Colombia is in the midst of an important shift: trying to balance its society and economy in the wake of the 2016 peace-agreement, with protection and restoration of important ecological regions. The mountainous Andean páramos ecosystem and paramuno/paramero campesinos of Boyacá have found themselves at the centre of some of these challenges. The páramos and their people – predominantly socio-economically precarious campesino farmers – are facing conservation policies to delimit, protect and control their livelihoods. Using a combination of qualitative methods, including interviews and participant-observation, to foreground campesinos' experiences, this paper explores the socio-environmental tensions emerging amidst this context of conservation. This paper argues that the delimitation process is constitutive of neoliberal conservation, which prioritises land sparing, ecosystem service payments and other 'green business'. Furthermore, the delimitation process does not address the structural factors driving environmental degradation in the páramos, which is linked to an agro-extractivist model. Over recent decades, campesinos have been driven into increasingly agro-extractivist farming which encourages specialisation, monocropping, intensification, and dependence on external inputs. Spatially this has pushed them up to expand the agricultural frontier, as well as pushed them down within and out of the páramos and farming livelihoods. Now additionally squeezed by conservation restrictions, the delimitation is exacerbating historic inequality and mistrust. As a mountainous, small-scale farming case-study, in a conflict setting, this is a novel and unique addition to agro-extractivism research. Analysing the delimitation process through neoliberal conservation and agro-extractivism provides a systemic approach, which highlights the inconsistencies and contradictions of the policies promoted in the páramos. The paper thus demonstrates how the neoliberal conservation agenda is not only compatible with but integral to the agro-extractivist landscape, as it compensates for environmental spill-overs without questioning the prevailing market model. Rather than seek more socio-ecologically just farming practices, it opens new frontiers for capital and compromises socio-environmental peace. • Campesinos in the Boyacá páramos have been driven into agro-extractivist farming. • Agro-extractivism has generated negative spatial, socio-economic and environmental consequences. • Colombia's post-peace accord conservation policies to protect páramos are neoliberal. • The neoliberal conservation agenda supports and compensates for agro-extractivism. • This worsens livelihoods, reinforces historic inequalities and mistrust, and compromises socio-environmental peace.

Introduction: Climate change poses a significant threat to rural livelihoods in low- and middle-income countries. Enhancing the sustainability of these livelihoods is crucial for ensuring food security and nutrition at both global and regional levels. This study investigates the role of Climate Smart Agriculture (CSA) practices in improving rural livelihoods in Latin America, specifically through the Climate Smart Village (CSV) approach. Methods: Our analysis involved a dataset of 267 households, comprising both adopters and non-adopters of CSA practices in CSVs across Guatemala, Honduras, and Colombia. We employed multiple correspondence analysis (MCA), Gower’s metric, agglomerative clustering, partitioning around medoids (PAM), and cluster validation. Our aim was to understand how CSA practices, which include the use of agroclimatic information, soil and water management practices, and risk diversification strategies, contribute to enhancing livelihoods. We examined this in the context of the five capitals (social, natural, physical, financial, and human) of the Sustainable Livelihoods Framework (SLF). Results: Our findings indicate that CSA farmers exhibit lower capital-based vulnerability compared to non-CSA farmers. This is particularly evident in the areas of social capital, as well as human and natural capital for certain CSA adopters. However, the similar performance in financial and physical capital between CSA and non-CSA farmers suggests the need for additional strategies to reduce vulnerability in these areas. We examined this through the Sustainable Livelihoods Framework (SLF), which includes five capitals: social, natural, physical, financial and human. Conclusion: These findings offer a valuable framework for policy and decisionmaking processes, helping to identify which capitals and dimensions of livelihood vulnerability should be prioritized in different contexts to achieve climate resilience and sustainable development. The study advocates for continued research efforts, incorporating expanded indicators, such as gender indicators within social and human capital definitions, for a more comprehensive assessment of CSA’s impact. The application of SLF for analyzing CSA’s contribution to rural livelihoods represents a novel approach in Latin American studies. [ABSTRACT FROM AUTHOR]

The illicit coca economy has become a bulwark for smallholder farming in Colombia. This article helps explain why. Analysis of the social relations surrounding coca production in one of the country's most important coca-producing municipalities shows that capitalist market imperatives are weak within this economy. Pressures to increase productivity are muted by fluid access to land, non-interest-bearing debts, and the lack of price competition between producers. Coca-growers are 'improving' production, but they mostly respond to opportunities rather than imperatives. In the context of multiple agrarian crises, the coca economy allows even less well-off producers to survive. [ABSTRACT FROM AUTHOR]

The effectiveness of conservation interventions such as Payments for Environmental Services (PES) is often evaluated--if it is evaluated at all--only at the completion of the intervention. Since gains achieved by the intervention may be lost after it ends, even apparently successful interventions may not result in long-term conservation benefits, a problem known as that of permanence. This paper uses a unique dataset to examine the permanence of land use change induced by a short-term, asset-building PES program implemented in Quindío, Colombia, between 2003 and 2008. This the first PES program to have a control group for comparison. Under this program, PES had been found to have a positive and highly significant impact on land use. To assess the long-term permanence of these changes, both PES recipients and control households were re-surveyed in 2011, four years after the last payment was made. We find that the land use changes that had been induced by PES were broadly sustained in intervening years, with minor differences across specific practices and sub-groups of participants, indicating that these changes were in fact permanent. The patterns of change in the period after the PES program was completed also help better understand the reasons for the program's success. These results suggest that, at least in the case of productive land uses such as silvopastoral practices under conditions such as those at the study site, asset-building PES programs can be effective at encouraging land owners to adopt environmentally-beneficial land management practices and that the benefits will persist after payments cease.

This paper contributes to agrarian debates through a discussion of the interactions between the interests and incentives of the rural classes, focusing especially on the leadership exercised by middle-size farmers. In the recent past, class analysis associated with Marxism has given way to models of individual rational maximization, not least because of the lack of specific findings about the effects of peasant differentiation beyond the dichotomous class conflict between peasants and landlords. Information has replaced asset distribution as the main factor affecting effective governance and service provision. According to these theories, politicians did not deliver less because they were responding to the preferences of the large landowning classes, or because seemingly competitive elections were games of rotating chairs within a single dominant class but, rather, because the voters did not have enough information about the candidates and programmes. I bring the discussion back to peasant differentiation and class endowments using the case of communal action boards in Colombia, showing how the demand for information on candidates and developmental resources matters, but is dependent on class structures. I suggest that different rural groups access, use, and manipulate information with differing aims, and that the rural middle class is a fundamental actor in the demand for public goods.

[Display omitted] • Soils under anthropic uses showed more remarkable changes in soil properties with rainfall seasonality than soils under natural páramo. • Land-use change from natural vegetation to potato and onion crops followed by fallow reduces soil organic matter and water content and increases bulk density. • Land-use change could impair the ability of páramo catchments for streamflow buffering and this could increase surface runoff and reduce base flow. High-Andean páramos deliver essential ecosystem hydrological services from a combination of soil, vegetation, and climate characteristics, particularly in their natural state. However, agricultural activities considerably affect the páramo's ability to store, regulate, and supply water. Although there is information on the effect of potato crops (Solanum tuberosum) on páramo soils' properties, the effect of spring onion (Allium fistulosum) crops has been studied less. In addition, dry páramos are underrepresented in existent páramoś research. This study assessed the effect of rainfall seasonality (RS) and land-use change (transformation from páramo vegetation to crops) on soil hydrophysical properties associated with hydrological services (streamflow buffering) in a dry páramo in the Eastern range in Colombia. Six dominant land uses were studied: natural páramo vegetation (low slope, steep slope, and dense shrublands) and anthropic use (onion crops, potato crops, and fallow). An in-depth random stratified discrete design (0–5, 10–15, and 20–25 cm) was used to collect samples for analysis of soil organic matter (SOM), bulk density (BD), pH, and electrical conductivity (EC). Hydrophysical properties were measured at the soil surface: water retention capacity (WRC), structural stability (SS), and infiltration capacity (IC). Soils under anthropic uses showed more remarkable changes in soil properties with RS than soils under natural páramo. On the other hand, land-use change from natural vegetation to potato and onion crops followed by fallow leads to a reduction in SOM (9.8 %) and an increase in BD (0.19 gcm−3), especially at the surface level. In addition, this leads to a loss of WRC (20 % at field capacity), an increase in unstable aggregates (13 %), water erosion, and a loss of IC (44 mmh−1). This paper demonstrates the impact of land use on soil hydrophysical properties that compromise the maintenance of hydrological services and contributes to a better understanding of the complexity of Andean páramos.

Enhanced anthropogenic climatic variability challenges small farmers. In the Sumapaz páramo (Colombia), higher irregularity in precipitation and temperature reduces the quality of pasture and cattle health. Data from surveys, semi-structured interviews, and focus groups were analyzed to understand livestock farmers' responses to the impacts of climatic variability. To estimate the communities' resilience in the páramo, we used the capitals framework, the Baseline Resilience Indicator for Communities (BRIC), and cluster analysis. The responses of most households aim to reduce the impacts of climatic variability on the production system, chiefly intensifying practices such as the rotation of paddocks, livelihood diversification, purchase of grass, and buying and selling livestock. Interestingly, farmers did not recognize the value of the types of capital for responding to climatic variability. Results showed that the use of available physical, social, and economic capitals render the farming system resilient. Our probit model estimated that economic and human capitals are the largest and most significant contributors to communities' capacity to respond to climatic variability. However, pre-existing non-climatic vulnerabilities are also important. For example, poverty hinders farmers from using their income in response to climatic variability. The place-based measurements used in this research are easily understood and applicable by local policy makers to address increasing climate variability. [ABSTRACT FROM AUTHOR]

Public Law 480 (PL 480), signed by President Dwight Eisenhower in 1954, inaugurated the most important and enduring international food security program launched by the United States. This paper focuses on the application of this law, from its approval, to its transformation into the Food for Peace Program (1961), and relies particularly on Congressional Records and the collection of records of the Foreign Relations of United States (FRUS). By analyzing the application of the PL 480 in Colombia, the paper argues that this program, initially designed to eliminate the surpluses of US agricultural production, became a cornerstone of US economic assistance towards developing world. The study of the impact of PL 480 on Colombian economy, made through the reports produced by Colombian and US agencies, shows that the proceeds of the sales of US products were reinvested into programs of technical assistance aimed at improving the productivity of the agricultural sector in Colombia. This use of sales proceeds corresponds to a turning point in US-Latin American relations in which food aid and foreign technical assistance coincided. Colombia is a particularly important example of this dynamic. [ABSTRACT FROM AUTHOR]

Quantifying dermal exposure to pesticides in farming systems in developing countries is of special interest for the estimation of potential health risks, especially when there is a lack of occupational hygiene regulations. In this paper we present the results of a dermal exposure assessment for the potato farming system in the highlands of Colombia, where farmers apply pesticides with hand pressure sprayers without any personal protective equipment. The fractioning of the pesticide, in terms of potential and actual dermal exposure, was determined via the whole-body dosimetry methodology, using the tracer uranine as pesticide surrogate, and luminescence spectrometry as analytical method. We assessed the three activities involved in pesticide management: preparation, application, and cleaning; analyzed three types of nozzles: one with a standard discharge and two modified by farmers to increase the discharge; and derived the protection factor given by work clothing. Our results suggest that to reduce the health risk, three aspects have to be considered: (i) avoiding the modification of nozzles, which affects the droplet size spectrum and increases the level of dermal exposure; (ii) using adequate work clothing made of thick fabrics, especially on the upper body parts; and (iii) cleaning properly the tank sprayer before the application activity., (Copyright © 2012.

The achievement of education in rural populations was one of the Millennium Development Goals (MDGs), outlined by the United Nations. During the last World Summit on Sustainable Development (WSSD), it was concluded that the majority of the world's poor, illiterate and undernourished population lives in rural areas; therefore, access to education is considered one of the greatest challenges for governments in countries with developing economies. The purpose of this study was to determine how a theoretical-practical training program in rural management and leadership (D-ML), artificial insemination (DAI), and bovine genetic improvement (D-GI) affected the perception and level of knowledge in a rural population affected by Colombia's armed conflict. Phase 1 included the theoretical and practical training of undergraduate animal sciences students in three dimensions (D-ML, D-AI, D-GI). After training, students were evaluated according to their level of theoretical-practical knowledge and their behavioral performance. There were 13 students selected to be a part of what we went on to call "the group of student leaders." Phase 2 included the socioeconomic characterization and training of rural residents by the group of student leaders and field experts in the same three dimensions (D-ML, D-AI, D-GI). We evaluated the perception and level of knowledge before and after training in 63 rural residents using an evaluative instrument. The perception of knowledge in rural residents was low for general knowledge (GTD) (2.48 ± 0.76, p < 0.05), D-ML (2.89±1.18, p < 0.05) and D-AI/D-GI (2.17±0.83, p < 0.05), in accordance with the 5-point Likert-type ordinal scale. When level of knowledge was measured before the theorical-practical training, the level of GTD was 45.9%, however, after the training it increased to 77.6% (p<0.01), while the level of knowledge for D-AI increased from 38.5% pre-training to 80.6% (p <0.05) post-training, and level of knowledge for D-GI pre-training was 50.8% and increased to 73.0% (p<0.01) post-training. Finally, the level of knowledge for D-ML increased (p<0.01) from 54.8% pre-training to 75% post-training. Altogether, rural extension programs contribute to closing knowledge gaps in relation to the use of reproductive biotechnologies and bovine management in rural areas affected by armed conflict.

The potato is one of the main agricultural products in Colombia and is the second most important crop in the country. The production of this tuber represents 3.3% of the country's agricultural gross domestic product (GDP). More than 100,000 producer families subsist on cultivation at the national level, the vast majority of which are smallholdings. However, smallholders are not able to exploit the full potential of this activity, and one of the main factors that does not allow for improving productivity is the inefficient use of land in agricultural activities. This leads to issues such as erosion, overexploitation of soil resources, reduced productivity, and, depending on the time of year, even an excess of potato supply. Therefore, a multicriteria methodology is proposed based on the key elements of the potato crop production cycle and its environment, made up of farmers from the municipality of Ventaquemada, located in Boyacá, where potato cultivation is a traditional practice. This department is the second-largest potato-producing department in the country. A review of the literature was carried out to determine and characterise the area of the selected department, and based on the above, the relevant criteria were defined and the alternatives to be evaluated were identified. Second, the proposed model is evaluated with its respective prioritisation process of both the criteria and the alternatives according to the analytic hierarchy process (AHP) methodology. Finally, the results of the model are presented, prioritizing the type of tillage, irrigation method, seed type, and its disinfection process for potato cultivation. This takes into account topographic and climatic conditions, the ecosystem, soil type, implementation costs, among other factors specific to the case study. [ABSTRACT FROM AUTHOR]

In Colombia, 98% of landmines occur in rural areas, where the main victims of amputation are farmers. The challenges these amputees face in their agricultural work remain unknown. The aim of this study is to determine the mobility and postural limitations these farmers face in carrying out their daily activities. Forty-nine participants meeting the following criteria were interviewed: transtibial amputee, 18 years and over, performs agricultural labour and wears the prosthesis daily. Subsequently, the interview transcripts were subjected to a content conventional analysis and responses were organized according to the abstraction process to identify categories and subcategories of the problems. Main problems reported were walking on sloping, uneven and wet terrain, problems associated with the stump skin, squatting, kneeling, using vehicles or animals for transportation and carrying objects over 30 kg. Postures such as sitting, running, jumping, and standing on tiptoes were mentioned less frequently. In conclusion, the prostheses worn by transtibial amputee farmers are not suitable for working on sloping and uneven terrain, nor for performing postures such as kneeling or squatting. These postures are very common in agricultural and livestock tasks in countries with mountainous areas such as Latin American countries. The recognition of problems reported by farmers transtibial amputees, may help to improve the design of prostheses so that they meet the needs of this population and decrease secondary injuries associated with prosthetic use. This information is useful to identify compensatory postures that facilitate prosthetic adaptation and rehabilitation for amputees. [ABSTRACT FROM AUTHOR]

Highlights • A stochastic optimization model for sugarcane supply chain planning is proposed. • The model integrates sowing, growing and harvesting operations. • Strategic and tactical decisions are simultaneously considered. • Financial feasibility for a new agro industrial project is assessed. Abstract The aim in new agricultural investment projects is to achieve a proper balance between customer value creation and investor economic benefits. Several authors have highlighted the importance of integrating agroindustrial supply chain operations, as a way to improve competitiveness. In the specific case of sugarcane, most research only integrates harvest and transport operations, lacking simultaneous analysis of sowing, growing and harvesting. Also, from the perspective of sugarcane supply chain planning, few contributions undertake tactical and strategic decisions. This paper proposes an optimization model for sugarcane supply chain planning, integrating several agricultural decisions from a strategic-tactical planning perspective. The uncertainty effects generated by weather conditions were also considered. As a main contribution, the model establishes a set of agricultural decisions that maximize cane yield, in order to optimize the Net Present Value (NPV) of expected profits. The proposed model is utilized to evaluate the feasibility of a new biofuel production plant in Colombia. Results allowed for the identification of critical variables to control, in order to reduce investment risk. [ABSTRACT FROM AUTHOR]

Agroindustrial wastes are a type of biomass generated mainly by organic materials processing, which come from animal handling, plant cultivation and fruit and vegetable processing. The aim of this paper is to propose possible alternatives to use 19 wastes generated in the Colombian agroindustry by fruit processing. These alternatives of use are formulated based on the waste physicochemical characterization, which was carried out through proximate analysis, ultimate analysis, analysis of structural carbohydrates and extractives compounds, total phenolic compounds content and antioxidant capacity. It was found that most of the wastes can be used as raw material in thermochemical processes. It was also found that the coffee grounds have the greatest alternatives of use, which goes from co-combustion with mineral coal to obtaining secondary metabolites. [ABSTRACT FROM AUTHOR]
