Potato-pasture production systems are key agricultural production systems in the Andean region of Ecuador and Peru. In potato cultivation, planted areas have decreased by more than half, while yields have increased, possibly due to the increased application of agrochemicals, which may lead to soil infertility issues. For pastures, the expansion of planted areas has been driven by the high unmet demand for milk and dairy products. These systems rely on specific management practices: in potato cultivation, excessive soil tillage and indiscriminate use of nitrogen fertilizers are common, while in pasture systems, the main challenge is inefficient management.
The implementation of conservation agriculture practices, such as minimum or reduced tillage, soil cover with residues, and crop rotation, is expected to have positive impacts on farmers who adopt them. These technological innovations in conservation agriculture enhance the sustainability of cropping systems and provide additional benefits beyond the farm, such as reduced soil erosion and improved soil quality. Additionally, the precise measurement of GHG emissions will allow for the evaluation of these practices' impact and the refinement of strategies to mitigate climate change. The combination of these technologies will help provide guidelines for achieving a more sustainable and resilient agriculture, adapted to specific regional conditions in both countries.
The study aims to identify livelihood strategies in potato-pasture production systems, through the classification of producers based on their productive approach and the analysis of climatic conditions. Additionally, conservation agriculture will be promoted to increase yields, soil fertility, and economic benefits, while reducing GHG emissions. Databases and technical documentation will be developed to compare GHG fluxes with IPCC estimates and support decision-making. Finally, farmers' capacities will be strengthened to adopt sustainable agricultural practices with lower environmental impact.
