Joint Experiment of Crop Assessment and Monitoring

Crop Assessment

The overarching goal of JECAM is to reach a convergence of EO approaches, develop monitoring and reporting protocols and best practices for a variety of global agricultural systems. JECAM will enable the global agricultural monitoring community to compare results based on disparate sources of EO data, using various methods, over a variety of global cropping systems.

The JECAM initiative is developed in the framework of GEO Global Agricultural Monitoring (GEOSS Task AG0703 a) and Agricultural Risk Management (GEOSS Task AG0703 b).

Agriculture and Agri-Food Canada (AAFC) has taken on the secretariat role of the JECAM project on behalf theGEO Agricultural Monitoring Community of Practice.

In 2011, CEOS initiated efforts to supply JECAM users with relevant remote sensing data through a coordinated EO data acquisition program of CEOS Agencies and commercial data providers.

The UK contribution to JECAM is 22m optical imagery from UK-DMC2. DMC International Imaging Ltd is providing multi-temporal datasets for JECAM test sites in Paraguay,Argentina,USA,Canada and Russia where the lead scientists requested UK-DMC2 data. The data requirements for each test site are typically 1-2 cloud-free coverages per month for 3-9 months of each year.

The multi-temporal datasets will be exploited by the science teams in each country for applications such as crop identification, mapping agricultural areas, estimation of biophysical variables, identifying phenological events, mapping the efficiency of water and nitrogen use, carbon sequestration and CO2 emissions, and monitoring the impact of beneficial management practices on a variety of crop types.

DMCii anticipates playing a prominent role in the long-term global system of systems for agricultural monitoring due to its unique ability to cover very large agricultural areas on a highly regular basis at high resolution, utilising multiple wide-swath satellite sensors.
