Expert meeting on crop monitoring for improved food security
17 February 2014, Vientiane, Lao PDR
The Food and Agriculture Organization of the United Nations (FAO) in partnership with Asian Development Bank (ADB), and in collaboration with the Sustainable Agriculture and Environment Development Association (SAEDA), organized an Expert Meeting on Crop Monitoring for Improved Food Security as a side event prior to the 25th APCAS in Vientiane, Lao PDR.
Purpose The objective of the Expert Meeting was to share best practices and experiences in the region in estimation of crop area and yields. The meeting focused on three themes: (1) Estimation of land cover, land use and crop area, (2) Crop yield monitoring and forecasting, and (3) Crop yield estimation using probability surveys and objective measurements.
Participants The meeting was attended by experts from international organizations like ADB, AFSIS, and IRRI and individual experts from Australia, Bangladesh, Bhutan, China, Fiji, India, Indonesia, Iran, Japan, Lao PDR, Pakistan, the Philippines, Republic of Korea, Thailand, Timor-Leste, USA and Viet Nam. About fifty experts and representatives of national statistical systems in the region attended in the meeting.
Key Conclusions Sixteen technical papers were presented and discussed in the meeting. The meeting concluded that while there exists a good potential for use of remotely sensed geographical data for improving estimates of crops area and yield, the countries need caution in adopting these technologies as full replacement of ongoing sample surveys and field reporting practices. In deciding the appropriate methodology for a specific situation, budgetary consideration for implementing the methodology plays an important role.
