“…The environmental conditions of each locality are described in Table 1. Regarding edaphic characteristics, the area under study is characterized by superficial soils of volcanic origin with low organic matter content, medium natural fertility, and high susceptibility to erosion [15]. The rational use of natural resources and the economic and social development of fruit growers were evaluated using the methodology proposed by Sepúlveda et al [16] and Parchomenko et al [17].…”

Human development must ensure the welfare and survival of an ever-growing population. To assess the impact of agroecosystems on sustainability in Nariño (Colombia), variables related to sustainable development were evaluated through a semi-structured survey conducted with 122 producers from 6 municipalities in the Nariño department. The association between the categorical variables associated with the pillars of sustainability was analyzed using multiple correspondence analysis (MCA). From the MCA, 23 indicators were selected, representing quantitative information on the economic, social, and environmental characteristics of the participants. The municipalities were characterized according to the needs and strengths of the producers. Five groups encompass most characteristics of the producers, which are largely independent of geopolitical conditions. On the other hand, the population characterization indicates that the economic well-being of fruit growers can promote the conservation of natural resources. Finally, a principal component factor analysis (PCFA) was conducted to construct the General Sustainability Index (GSI). A network graph for each municipality revealed that the indicators of the production systems are in an unfavorable environment in almost all aspects related to sustainability. The GSI values reveal unstable agroecological conditions that are causing environmental deterioration, with critical levels in the municipalities of Arboleda, Sandoná, and Providencia. Social investment and public policies must be implemented to improve the economic conditions of the producers, accompanied by legislation on the proper management of natural resources.

“…The effects of human intervention on paramos are not limited to changes in vegetation type: the use of pesticides is an increasing source of soil and water contamination as agriculture expands, and can affect the quality of the water supply in the high catchments [123][124][125][126][127]. Furthermore, potato crop and livestock activities affect the physicochemical properties of the soils [130,131], including a reduction in carbon storage and cation exchange capacity [132].…”

Paramos, unique and biodiverse ecosystems found solely in the high mountain regions of the tropics, are under threat. Despite their crucial role as primary water sources and significant carbon repositories in Colombia, they are deteriorating rapidly and garner less attention than other vulnerable ecosystems like the Amazon rainforest. Their fertile soil and unique climate make them prime locations for agriculture and cattle grazing, often coinciding with economically critical deposits such as coal which has led to a steady decline in paramo area. Anthropic impact was evaluated using multispectral images from Landsat and Sentinel over 37 years, on the Guerrero and Rabanal paramos in central Colombia which have experienced rapid expansion of mining and agriculture. Our analysis revealed that since 1984, the Rabanal and Guerrero paramos have lost 47.96% and 59.96% of their native vegetation respectively, replaced primarily by crops, pastures, and planted forests. We detected alterations in the spectral signatures of native vegetation near coal coking ovens, indicating a deterioration of paramo health and potential impact on ecosystem services. Consequently, human activity is reducing the extent of paramos and their efficiency as water sources and carbon sinks, potentially leading to severe regional and even global consequences.

“…Different from the Orinoco River basin, in the Colombian Pacific region, students will face the highest annual rainfall (6-7 m annually) in addition to highly acidic soils ( IDEAM et al, 2017 ; Quinto-Mosquera and Moreno, 2017 ). In the Caribbean region they will face climate extremes - humid and dry forests, wetlands and deserts - all which share eroded soils with low soil organic matter ( Quintero-Angel and Ospina-Salazar, 2022 ). The Andean region has a bimodal rainfall regime and a topography of steep slopes that result in sheet erosion ( Quintero-Angel and Ospina-Salazar, 2022 ) and the Amazon region is an ecosystem rich in biodiversity that is highly susceptible to degradation when inadequate agricultural and livestock practices interrupt conserved land cover ( Murillo-Sandoval et al, 2023 ).…”

This diversity of regions and ecosystems in Colombia also determines the country’s agrobiodiversity: even commercialized crops are adapted over time to each region and the particularities of local food systems, an additional consideration for La Salle students.…”

Exploring the future of GM technology in sustainable local food systems in Colombia

et al. 2023

The security of Earth’s food systems is challenged by shifting regional climates. While agricultural processes are disrupted by climate change, they also play a large role in contributing to destabilizing greenhouse gases. Finding new strategies to increase yields while decreasing agricultural environmental impacts is essential. Tropical agriculture is particularly susceptible to climate change: local, smallholder farming, which provides a majority of the food supply, is high risk and has limited adaptation capacity. Rapid, inexpensive, intuitive solutions are needed, like the implementation of genetically modified (GM) crops. In the Latin American tropics, high awareness and acceptance of GM technologies, opportunities to test GM crops as part of local agricultural educations, and their known economic benefits, support their use. However, this is not all that is needed for the future of GM technologies in these areas: GM implementation must also consider environmental and social sustainability, which can be unique to a locality. Primarily from the perspective of its educators, the potential of a rural Colombian university in driving GM implementation is explored, including the role of this type of university in producing agricultural engineers who can innovate with GM to meet regionally-dependent environmental and cultural needs that could increase their sustainability.
