(Brasil's National Supply Company) is the government agency responsible for providing information on the country's agricultural harvest. Their information is used by market analysts around the world and is included in the monthly report of the Agricultural Market Information System via the GEOGLAM Crop Monitor for AMIS
Conab seeks training so that its technical staff can update the new methodologies and technologies that can be implemented in its work.
Through AMA and NASA Harvest, Conab participated in three training workshops in 2018 that have improved the usage of EO in Brazilian national crop assessment.
In March 2018, NASA Harvest
and UMD GLAD
hosted a workshop at UMD on national-scale cropland and crop type mapping. Technicians from Conab together with those from INIA (Chile), SIAP (Mexico), and MinAgri (Argentina) participated in the training. The week concluded with initial discussions that led to the successful launch of AMA
In August 2018, during the AmeriGEO Week held in São José dos Campos, São Paulo, a follow-on course, “Sample-based area estimation from remote sensing” sponsored by AMA was delivered by Viviana Zalles (UMD GLAD).
Since then, Conab has been testing the methodology to classify croplands in Brazil. The first test of the methodology was the mapping of rice in the state of Paraná. The result obtained was not satisfactory and adaptation needs were identified. A second test was carried out to estimate the area of Maíz 2ª Safra (2017/18) in the Federal District. The map used as the basis for the stratification was that of the first crop, since the area cultivated in the region is the same in the two crops (changing only the types of crop). Therefore, the possibility of estimating the area of the main crops of the first and second crops using only a mapping as a basis was also studied. After drawing the points, a fieldwork was done to validate them. Once the work was finished, the result was announced to and well-received by the agricultural sector of the region.
Consequently, Conab adopted the result (35,800 hectares) as official data for the area of the second corn crop in the Federal District.
Given the success of the application of the methodology, the work was presented to the Living Planet Symposium 2019 in the GEOGLAM session (photo, inset). Conab now wishes to implement the area estimation methodology in other states and with other crops.
In addition to these two trainings, Conab participated also in a December 2018 workshop on the applications of SAR technology for agricultural monitoring were shown. Hosted in Ottawa, Canada at Carleton University, organized by Agriculture and Agri-Food Canada (AAFC) and funded by the IICA Scholarship and Research Assistance Program 2018 Canada for agriculture in the Americas. With the qualification and exchange of experiences of its technical staff with specialists in agricultural monitoring in the world, Conab reaffirms its search to always improve the quality of its information.
