Abstract

This summary paper highlights agricultural information needs and priorities in South/Southeast Asian (S/SEA) countries. We distinguish two important agricultural information user groups – government agencies or policymakers and individual farmers. Both these groups are interested in information and data for different purposes. For example, government agencies and policymakers are most interested in addressing local, regional, or country-level food security and policy needs; in contrast, individual farmers are concerned with timely information on crop management relevant to field scale. This study discusses these needs, including capacity building and development, including strengthening cooperation among regional space agencies to address agricultural needs specific to S/SEA countries. The priorities summarized in this study were identified by the in-country researchers and practitioners, shared during several South/Southeast Asia Research Initiative (SARI) meetings and workshops organized since 2015. The rapid increase in agricultural technology in other parts of the world has a slower uptake in this region, which remains predominantly smallholder farming where the initial cost of such investments is prohibitive. Though there has been an increase in free and openly available satellite data, remote sensing remains a largely untapped tool to address national food security and individual farmer needs. Although several encouraging studies have appeared in recent literature on agricultural research and applications in S/SEA, those demonstration studies need to transition from research to operational products or systems useful for those involved in agricultural resource management. The study also calls for international cooperation to aid in transferring geospatial tools and technologies to assist in food security needs and sustainable agriculture in the many varied landscapes of S/SEA.

Dr. Shibendu Shankar Ray, a great friend, and colleague of the co-authors, tragically passed away on May 4th, 2021. Although Dr. Ray was involved in the early stages of this chapter, he was unable to participate in its completion.
