The development of the extractivist model in Argentina has numerous consequences for the territories and the human and non-human beings that inhabit them. Changes in land use, 'development' infrastructures, technological packages and land grabbing expel their inhabitants to other areas of the country, generally urban, where, far from finding better living conditions, they deepen existing inequalities. In this sense, we propose in this article to analyse those mobilities that involve members of indigenous peoples by describing the environmental scenarios from which they are expelled, mainly in the Chaco region, and the destination territories where these groups converge, focusing on the Metropolitan Region of Buenos Aires. This article is based on information obtained from previous research, fieldwork and field notes, in-depth interviews, analysis of statistical sources, cartographic data and specialised literature on the subject.

The methodology applied for the development of the research process is framed in a conceptual basis associated with the systemic approach of the territory and the landscape units as a tool for their multiscale planning; and the municipal territorial diagnosis that allowed evidencing the potentialities and land and use conflicts associated with the construction and operational- ization of the multipurpose reservoir Topocoro. As a result, a series of strategic guidelines for sustainable development is obtained that serves as the basis for the structuring of a sustainable land management model that allows to organize the municipality of Betulia in macro units and landscape units focused on configuring plot units on sites that do not mainly affect biotic and abiotic mass, contribute to economic reactivation and the improvement of the living conditions of local communities.

Knowledge regarding soil wetness dynamics is relevant for its application in hydrological and climatological studies. It is also a parameter that allows the analysis of processes related to land cover and land use. Due to this importance, the spatio-temporal dynamics of the surface soil humidity (SSH) in the southern of the Argentinean Pampean Plains have been analyzed, based on data corresponding to six Argentine localities and in relation to a climatological index that incorporates rainfall and evapotranspiration variables. The methodology includes statistical correlation and multivariate analysis based on modeled and reanalysis data. The results obtained reveal a different response of the SSH at a spatial level, with maximum values in the highest rainfall region, diminishing towards the most arid zone. This allows us to infer the influence of the topographic homogeneity of the area and the predominance of vertical processes in the hydrological balance. At both a spatial and temporal scale, the SSH dynamics concur with the climatological index pattern, confirmed by a Pearson coefficient. It has also been shown that the SSH responds to the climatological parameters and that the highest correlation occurs at a three-month temporal scale. This response may be observed at an interannual and annual level, with maximum and minimum values during the wet and dry years, respectively and a decrease in the SSH during the warmest seasons (summer). The SSH displays the same tendency as the climatological index, from NE to SW, reaching a maximum in the rainiest area and minimum in the arid region. The manuscript, based on diverse sources analysis, pluviometric periods classification and statistical methods application, is a contribution related to the edaphic variable dynamics in a region in which farming activity constitutes the main land use and where the droughts and floods alternance has effects on the flooding risks and the economic losses as a consequence of intensive droughts, respectively.

Approximately 5% of the total emissions (0.11 Gt CO2 and GWP-AR5) originate in Rio Grande do Sul state (RS), a representative agricultural region in Southern Brazil. This study assessed SOCS (soil organic C stocks) in Latossolos of the Planalto of RS, with up-to-date data obtained from recent field campaigns and legacy data, and relate these SOC stocks to environmental variables. A literature search identified 195 documents with SOCS in layers 0-30 cm and 0-100 cm. The mean SOCS (0-30 cm) in the Latossolos was significantly higher (73.6 Mg ha-1) than the suggested IPCC default (55 Mg ha-1). The highest stocks (237 ± 39 Mg ha-1) were measured in uncultivated Latossolos Brunos in the 0-100 cm layer, especially at higher altitudes and lower mean annual temperature. The most frequently occurring soil Latossolo Vermelho distroférrico-LVdf (25% of the Planalto), also had high SOCS. Surprisingly Latossolos Vermelho Distrófico (LVd) also had high SOCS, in spite of the coarser texture. The estimated SOCS in Latosoolos of the Planalto is 419.9 Tg C, 36% larger than reported previous studies. We concluded that, despite significant land use changes, soils of this region maintain large SOCS which had been underestimated in previous studies. [ABSTRACT FROM AUTHOR]

Background and aims: The most substantial global land use change is the transformation of native ecosystems into agroecosystems, leading to loss of biodiversity and reduction of ecosystem services. Potentially, these degraded systems could be restored from their soil seed bank. Our aim was to assess species richness and density of the soil seed bank along a structural complexity gradient in agroecosystems and Espinal forest fragments. Furthermore, we compared species composition between the soil seed bank and established vegetation of the reference system to explore its potential for regeneration of native plant communities. M&M: A structural complexity gradient was created from vegetation and soil structural variables from plots with different land uses to analyze seed bank variables. Results: The highest richness was recorded in the pasture soil seed bank, followed by the forests. The highest density and similarity to the established vegetation of the reference system was registered in the forests. Herbaceous species predominated in all plots. With the exception of Celtis tala, seeds of dominant woody species from the reference system were not observed. Conclusions: The pasture seed bank may be particularly relevant in the early stage of native forest restoration, especially if the aim is to reduce costs. However, the contribution of the seed bank to Espinal forests recovery in short to medium term is limited due to its low similarity to reference system. [ABSTRACT FROM AUTHOR]

Neltuma flexuosa is the main tree species in the Central Monte which presents important ecological and socio-cultural functions. Grazing and wood extraction, the most widespread human uses in the region, can modify the growth of Neltuma trees and generate changes in the woodland dynamics, which, in turn, is influenced by water availability. Our aim was to assess the growth pattern of N. flexuosa trees that inhabit open woodlands of the Central Monte and associate it to land use and to the climate. Dendrochronological methods were employed to analyze wood samples collected in areas destined for conservation, grazing use and wood extraction. Trees in the wood extraction area grew approximately twice that of the individuals in grazing fields and the protected area between 1977 and 2000, reaching their maximum growth rate between 20 and 40 years of age. In opposition, the maximum growth rate in the protected area and in the grazing fields occurred at approximately 70 years of age. A positive correlation between rainfall and growth was observed, however the association between climate and growth was low. Our results show that the different land uses have affected the radial growth pattern of N. flexuosa trees. The resprout capacity of the species would have allowed its recovery at the tree level, which, combined with a change in the intensity of anthropogenic use, enabled the recovery of the N. flexuosa population and the reestablishment of the forest. These results suggest that the extensive grazing and the extraction of wood to domestic use are activities compatible with the sustainable use of the woodland. [ABSTRACT FROM AUTHOR]

Territorial Planning is a scientific discipline, aimed at achieving the physical organization of the space. The objective of the work was to present the main results of the implementation and operation of this service in sugarcane agriculture, which allows greater reliability in the control of the land and its use, support for decision making in planting programs, varieties, calculation of fertilizers, herbicides, production estimates, blocking and identification of limiting factors. Its implementation and operation defined the bases for updating the Specialized Cadastre in the sugarcane area of the country. It contributed to the performing of the program to bring the areas closer to the plant, allowing us to have an agricultural planning strategy that favors the correct use of the land, as well as the determination of vulnerable areas in the sugar mill companies with a view to facing the effects of climatic change. It constituted the geospatial expression of the scientific-technical services offered by the Sugarcane Research Institute to the farmer. It made possible the blocking of the sugarcane areas and the compaction of the blocks. The service facilitates efficient decision-making to establish comprehensive technologies, with impact on increasing agricultural yields. [ABSTRACT FROM AUTHOR]

The use of remote sensing and information on social factors specific to each population allows the monitoring of natural resource use. The main objective of this study is to determine the change and future projection of land use and land cover and, at the same time, to understand, from the perspective of the main stakeholders, the driving and underlying factors of these changes in the middle-upper Mira river basin. For this purpose, multispectral, Landsat, and Sentinel images from 1996, 2007, and 2018 have been used and pre-processed and treated. Subsequently, a forecast of land cover and land use changes from 2018-2030 has been made using TerrSet software. The drivers and underlying factors have been identified using the Delphi method. The results show that forests and pastures presented a sustained decrease, while cropland and urban areas increased between 1996-2018 and 2018-2030. These changes are related to urban, agricultural, livestock, mining, and forest industry growth, which are generally driven by population growth, market demand, changing consumption patterns, road expansion, and a lack of environmental policies.

Mass removal phenomena are potentially dangerous because they cause damage to property and infrastructure in communities. Therefore, there is a growing governmental interest in knowing, studying and zoning these phenomena, developing projects and research that allow evaluating their behavior. In this work, the zoning of the susceptibility to mass removal phenomena will be obtained, in the vicinity of the municipality of Pueblo Bello, Cesar, upper basin of the Ariguaní River, located southwest of the Santa Marta Nevada massif. For the execution of this project, the discriminant statistical method was developed, taking into account the conditioning and triggering factors, which quantitatively determine the degree of influence that each geoenvironmental variable has on the generation of mass removal phenomena. These geoenvironmental factors were carried out by visiting strategic points within the area, in order to build maps of geology, superficial geological units, geomorphology, land cover and land use, achieving an analysis that led to the determination of homogeneous zones, failure mechanisms, characterization of drainage and its relationship with the phenomena of instability. In conclusion in the sector there is a higher category of medium susceptibility with 45.46%, followed by the low with 20.07%, the high with 17.40%, the very low with 10.31% and the very high category with 6.73%. The relationship with mass movements is higher in the very high category with 36.58%, followed by the average with 31.70%, the low with 14.63%, high with 9.75% and the very low with 7.31%.

Parcel subdivision is the process that divides private property, impacting urban and environmental burdens on the territory. The municipality of El Carmen de Viboral in Antioquia, Colombia, has experienced the accelerated influence of this process. Although parcel subdivision is regulated by Colombian law, its effects have been insufficiently associated from an urban and environmental perspective. For this reason, this research conducted a spatiotemporal analysis of parcel subdivision in this municipality, aiming to identify potential land use conflicts. To achieve this, 720 licenses were analyzed, taking into account their year of issuance and location, which were intersected with the regulated land uses in the zoning plan (POT). As conclusions of this research, four different periods were identified, showing an increase in parcel subdivision on the outskirts of the urban area and potential land use conflicts generated in protected areas.

This manuscript provides insights about the persistence of peasant life in Los Chenchos, a riverine community in the Colombian Pacific. Following a social wellbeing approach, we examine the material, relational and subjective dimensions underlying the persistence of this community in their ancestral territory despite profound social and economic challenges marked by regional land use change and the emergence of illegal and extractive economies. We followed a sequential mixed-methods approach based on participant observation, ethnographic interviews and a descriptive census of the three dimensions of social wellbeing in the 18 households that make the community. Employing the social wellbeing approach provided an understanding of how achieving a desired way of life is an adaptive response that draws on values associated with small-scale agricultural production and family networks.

The change in land use resulting from human activities occurs at both global and local scales. The present research focuses on the multi-temporal analysis of land use change on Santa Cruz Island, Galápagos. Therefore, the analysis of land uses and their transition with vegetation cover was proposed to examine their evolution. Geographic Information Systems and the Supervised Classification technique were employed to identify changes in the terrain over time and the factors responsible for these alterations. In order to obtain accurate information about existing land uses in the study area, free satellite images were used, allowing the distinction of four distinct classes. Through this analysis, it was possible to determine the evolution of land use over a period of 32 years, spanning from 1991 to 2023. The results revealed that the classified areas underwent modifications due to both natural and human-induced factors, including livestock and agricultural activities, as well as demographic growth. To validate the obtained data, a confusion matrix was conducted, and the Kappa index was applied. These procedures demonstrated the robustness and agreement of the model used, ensuring high accuracy compared to reality. In conclusion, this study provides a comprehensive view of land use change on Santa Cruz Island, Galápagos, and offers relevant information about the factors that have contributed to such changes over time. The results have significant implications for sustainable land management and ecosystem conservation in this important region. [ABSTRACT FROM AUTHOR]

Carrying out land use statistics through remote sensors and Geographic Information Systems (GIS) allows obtaining not only numerical information but also thematic mapping of land uses. It is an important element for the analysis of territorial dynamics, allowing for interpretations to be made about the functioning and structure of the space to be analyzed, which results in very useful information for researchers or decision makers in general. This article presents the results of the analysis of the mapping of peri-urban land uses obtained by remote sensing in the period 1990-2023, for four neighborhoods in the city of Santa Rosa, La Pampa. The dynamics of the main land uses of the study area are analyzed, through the quantification and spatial distribution of eight identified categories: continuous and discontinuous urban; in the process of urbanization or vacant; industrial, commercial and other non-residential uses; urban equipment; horticultural crops and water. For the study and evolution of spatial distribution patterns of these categories, a cartographic overlay methodology is proposed by using GIS tools. [ABSTRACT FROM AUTHOR]

The use of fire has driven great changes in land cover. Although the occurrence of fires is modulated by climatic conditions and the availability of fuel biomass, human beings have modified historical fire regimes through various mechanisms. Therefore, in many environments, human activities are the main driver of the modern fire regime. In this study, we analyze fire incidence in the Argentine territory for the period 2000-2019. Specifically, we 1) characterize fire occurrence at the provincial level and 2) evaluate the spatial pattern of the burned area (BA); in the areas where BA was concentrated, we 3) describe environmental conditions (climate and vegetation) and 4) evaluate whether different land covers or uses were associated with certain characteristics of the modern fire regime (frequency and extent). Between 2000 and 2019, 47.84 Mha were burned, mainly concentrated in north-central Argentina. Within this area, we differentiated four climatic zones (wich were subtropical-humid, subtropical, temperate and temperatesemiarid), six vegetation units (Chaco, Monte, Pampas, Espinal, Yungas, and Paraná), and seven conglomerates of spatial association between land cover/uses and fire incidence. Fires associated with high-intensity land use occurred mostly in the subtropical and temperate zones, with vegetation of Chaco and Espinal units. Those related to low-intensity land uses were registered mainly in subtropical-humid and temperate-semiarid zones, with vegetation of Monte and Paranaense units. In most cases, fire was used to reduce or eliminate the cover of native species, either woody or herbaceous vegetation units, to promote the growth of cultivated (cereals, oilseeds) or forage-species (implanted or native), to foster agricultural and/or livestock production, respectively. Therefore, our results suggest that the high incidence of fires in central Argentina was associated with the current productive system. [ABSTRACT FROM AUTHOR]

The study of the environmental quality of the largest rivers such as the Paraná, is a challenge for the different disciplines of environmental sciences. Considering that the water quality of the largest rivers is mainly affected by the contributions of pollutants through the tributaries, we evaluate, using a multidisciplinary approach, the environmental quality of the tributaries of the Paraná River in Argentina, whose subbasins are associated with different levels and types of anthropization. We also discussed the aptitude of different diagnostic tools used to study the quality of water courses associated with rural landscapes and proposed a new indicator of easy measurement to quantify the level of anthropization in these environments. We selected 6 sampling sites (SM) related with different level of anthropization, considering agricultural and/or livestock (A/G) and urban or industrial (U/I) activities. The general parameters of water quality were measured in situ, and water and sediment samples were taken for physical, chemical, microbiological and ecotoxicological evaluation. The toxicity was evaluated by a battery of bioassays (Daphnia magna, Hyalella curvispina and Lactuca sativa). The frequency of bioassays that show significant effects correlated positively with anthropization. Lactuca sativa was particularly sensitive to pollutants of A/G origin, while crustaceans, to those from U/I. The combination of U/I and A/G activities increased the toxicological complexity of the watercourses, producing greater adverse effects. Although, in the rural areas the U/I activities represented a scale notably small in relation to A/G, their contribution to the deterioration of the toxicological quality of watercourses appeared significant.

The objective of this research is to characterize the hydrological network of the "Hondo" estuary micro-basin through the use of morphometric and biophysical parameters, in order to analyze and predict its hydrodynamic behavior, in order to contribute to environmental management plans and be a contribution to the conservation and protection of optimal conditions for their development. Three shape parameters, two of relief, its drainage network and physiography were analyzed. While in the biophysical variables they were calculated by means of ArcGIS geospatial information processing, identifying their temperature, precipitation, soil texture, land use and cover, slope and taxonomy. According to the results obtained, its morphometry the micro-basin presented an oblong or rectangular shape, a moderate drainage network, where it is concluded that its water system is not prone to present flood peaks, due to the stability of its runoff regimes. superficial. However, as it is a young basin and presents a concave hypsometric shape, it is likely that it will experience high erosive processes in the future. Finally, in the biophysical component it was identified that the texture of the soil was mostly sandy loam, with strong and steep slopes and a predominance of alfisols whose water filtration is low, where it is concluded that the micro-basin could present loss of the layer vegetative by dragging sediment.

The influence of land use on the content and distribution of soil carbonates was assessed in representative sites from three basins on the Santa Elena Peninsula. Two samplings were conducted: one at the surface, at a depth of 0-30 cm (Río Verde: 100 points; El Chaparral: 50 points; PIDAASSE: 100 points; Manglaralto: 50 points), and another at depth (0-10, 10-20, 20-40, 40-60, and 60-100 cm) in areas preserved under tropical dry forest. The Bernard calcimeter method was employed to determine equivalent calcium carbonate (ECC). It is concluded that soils in the investigated sites from different basins are slightly calcareous and exhibit low levels of total carbonates, thus not posing a potential problem for crops at present. The depth-wise distribution of carbonates in soils with alluvial influence may respond to sedimentological dynamics associated with rainy periods and cyclic extreme events. The influence of land use on ECC contents was evident, with statistically significant differences found for soils with lower anthropogenic intervention in sites with varying humidity gradients. However, no differences were observed between sites with the most contrasting climatic conditions, Manglaralto (sub-humid) and Zapotal (arid), under agricultural uses for short and intermediate crop cycles, attributable to the influence of agricultural practices. These results may be indicative of advancing desertification in the more humid regions of the northern peninsula. [ABSTRACT FROM AUTHOR]

The Paris Agreement was adopted at the 21st Conference of the Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC). Article 13 of the agreement establishes a Reinforced Transparency Framework (MTR) and the Capacity Building Initiative for Transparency (CBIT), which finances projects whose objectives are to implement tools for the development of technical and institutional capacities in the signatory countries. Cuba is already executing its first project in the AFOLU sector (Agriculture, forestry and other land uses) which aims to strengthen institutional capacities to respond to the MTR, aligned with national circumstances; technical capacities to assess and report on greenhouse gas emissions/removals and mitigation actions; and the technical capacities to monitor and report the impacts of climate change and adaptation actions. The project aims to organize the flow of information generated by the AFOLU sector on climate change and establish regulatory mechanisms, institutional alliances and methodologies to achieve this purpose, under the premises of the MTR. Precisely, on the context and some important elements that will make up the monitoring and evaluation (M&E) system, this point of view focuses on an approach to the organizational details that will allow international entities to be informed based on the commitment and integration of all stakeholders. actors of the AFOLU sector and the organization, quality and improvement of information in this sector.

This article deals with the socio-cultural dimensions of land in family de-agrarianisation processes, an invisible reality under economistic approaches to agrarian transformations. We analyse the values, duties, and imaginaries about land in different generations of families that run wine farms in Penedès region (Catalonia). Decisions about the family's land and its future orientations are ruled not only by market structures but by kinship and the moral codes of filiation and mutuality. Inherited land is still transmitted as an inalienable patrimony which cannot be freely disposed of and whose sale is perceived as illegitimate, even by de-agrarianisated generations. In a context of growing commodification, values, moral duties, and affections to the family's land do not diminish, but instead, under a contingent moral economy, compromise the de-agrarianisation and capitalist accumulation. Despite family de-agrarianisation, there are cultural resistances to abandoning agrarian production as a way of life. These resistances reflect intense cultural ideals and bonds with the land, that are difficult to change, embedded in kinship and out of step with the rapid material erosion of agrarian structures. Sociocultural de-agrarianisation is slower than the economic one. [ABSTRACT FROM AUTHOR]

At the center of global initiatives, various approaches are being discussed and realigned to achieve global objectives for production and food security for the present and future generations. However, agricultural systems, which are the main biogeophysical source for ensuring nutritional benefits and global food security, undergo changes over time. In the coming decades, these systems will face complex challenges, for example, associated with changes in food consumption patterns, climate change, land abandonment and/or intensification of land use. The ability of these systems to support global food security will be determined by their efficiency, sustainability, and equity. The integration of geospatial approaches to geographical research offers a practical opportunity to model agricultural systems, which, in turn, can contribute to obtain new data that assist in decision-making processes, anticipating future changes, and projecting long-term robust strategies to manage imminent challenges. This article presents a reflection on the development and integration of spatial analysis, geospatial data, and simulation models in the field of agricultural systems, highlighting and exemplifying different modeling techniques and geospatial technologies to support current and future research needs.
