SERVIR Develops Tool for Assessing Agricultural Practices

This entry originally appeared on ServirGlobal.net.

In SERVIR regions, agricultural measures such as irrigation, improved fertilization and advanced cultivars have the potential to increase food security and ensure climate resilience. However, to broaden support for such activities, environmental managers must be able to assess their impact. Because field data for estimating the impact of agricultural practices is often difficult to obtain, decisions about using them are often made based on limited information.

SERVIR has developed a user-friendly, web-based tool called AgriSERV that provides two important satellite datasets together in one system to help decision-makers in SERVIR’s data-sparse regions assess the impact of agriculture interventions. With this tool, development practitioners, scientists/researchers and government decision makers can visualize and download vegetation condition data and historical rainfall data. The specific datasets providing the basis for analysis are eMODIS Normalized Difference Vegetation Index (NDVI) and Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) rainfall data.

Vegetation health is a good indicator of crop vigor, and several studies have connected changes in satellite-derived vegetation indices to crop yields and the length of growing season. By analyzing the vegetation index data along with a rainfall dataset, areas with and without intervention can be compared and analyzed to assess the impacts of the intervention strategy and identify similar areas where the same strategy could be used.

With AgriSERV, users draw (delineate) two areas of interest... Read more on Servirglobal.net.
