Data or statistical facts on the situation and perspectives of agri-food systems and the impact of policies
The agrifood supply chain of Latin America and the Caribbean (LAC) stands out for its resilience to the COVID-19 pandemic, and multiple studies have been conducted to analyze the differential impacts of the pandemic across firms and sectors. Less is known regarding the strategies implemented for business continuity during this catastrophic shock. The purpose of this study was to analyze the respon...
6 of the 9 critical thresholds for Earth's stability have been exceeded, including biodiversity, land use, freshwater, biochemical fluxes, pollution and climate change (Richardson et al., 2023).
94% represents the reduction in species population abundance in Latin America and the Caribbean since 1970 (WWF, 2022).
262 (cotton) and 190 (citrus) plots were georeferenced to build NDVI series.
As a national pilot, PRODAF emphasized rigorous evaluation of productive and economic impacts.
NDVI-based remote sensing is a valuable, cost-effective proxy for yield to assess temporal dynamics of impacts.
Annual NDVI (average and maximum) is used to observe pre- and post-intervention trends for treated and control units. The longitudinal approach captures the "before and after" dynamics of the program.
The monthly NDVI signal shows greater variation in annual crops such as cotton and greater stability in perennial crops such as citrus.
The combined strategy of using surveys and satellite images allows for measuring mechanisms (adoption, credit) and returns, offering consistent evidence.
0.006 was the average DID effect on mean NDVI for citrus, indicating productivity improvement.
