The study shows that the 'Ataulfo' mango from Chiapas increases its sweetness and loses firmness as it ripens, which directly influences its post-harvest quality and export potential (Ortiz-Hernández, M. et al.,2012).

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 responses toward innovations of the LAC agrifood supply chain to the COVID-19 health emergency using data gathered from agribusinesses from 22 LAC countries. The study contributes to the literature by taking a comprehensive look at the responses of businesses along the LAC agrifood chains, and it is also one of the first longer-term quantitative assessments as it considers responses from the first and second years of the pandemic. The results from our two surveys show that over 70% of agribusinesses implemented innovations, revealing firms’ positive and prompt reactions. Although most innovations were longer-term, in many cases, innovations were only temporary. Statistical analyses suggest that the likelihood of implementing longer-term innovations is associated with the agrifood segment, the agrifood chain stage, receiving long-term public or private support, having access to credit, and positive future perspectives about business conditions.
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).
6 de los 9 umbrales críticos para la estabilidad y resiliencia de la Tierra han sido sobrepasados: integridad de la biósfera (diversidad genética), cambios de uso del suelo, uso de agua dulce, flujos bioquímicos (fósforo y nitrógeno), contaminación por químicos sintéticos y cambio climático (Richardson et al., 2023).

262 (cotton) and 190 (citrus) plots were georeferenced to build NDVI series.
262 (algodón) y 190 (cítricos) parcelas se georreferenciaron para construir series NDVI.
As a national pilot, PRODAF emphasized rigorous evaluation of productive and economic impacts.
El programa se concibió como piloto nacional y se subrayó la necesidad de evaluar rigurosamente sus impactos productivos y económicos.
NDVI-based remote sensing is a valuable, cost-effective proxy for yield to assess temporal dynamics of impacts.
El uso de NDVI como proxy de rendimiento es valioso y costo-efectivo para examinar la dinámica temporal de impactos.
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.
Con NDVI anual (promedio y máximo) se observan trayectorias pre y post intervención para unidades tratadas y de control. El enfoque longitudinal capta la dinámica “antes y después” del programa.
The monthly NDVI signal shows greater variation in annual crops such as cotton and greater stability in perennial crops such as citrus.
La señal NDVI mensual exhibe mayor variación en cultivos anuales como algodón y mayor estabilidad en perennes como cítricos.
The combined strategy of using surveys and satellite images allows for measuring mechanisms (adoption, credit) and returns, offering consistent evidence.
La estrategia combinada de utilizar encuestas e imágenes satelitales permite medir mecanismos (adopción, crédito) y rendimientos, ofreciendo evidencias consistentes.
