Which mission conducted an appraisal of the Philippines' agricultural extension service leading to significant reforms?

The World Bank mission conducted an appraisal of the Philippines' agricultural extension service, and its findings led to significant reforms in the sector. The World Bank's involvement typically includes assessing existing systems, identifying weaknesses, and recommending improvements to enhance efficiency and effectiveness in agricultural practices. Through comprehensive evaluation and analysis, the mission provided a framework for upgrading extension services, focusing on capacity building for extension personnel, improving service delivery, and fostering better farmer-organization linkages. This contributed to a more responsive agricultural extension system that meets the needs of farmers and promotes sustainable agricultural development.

The other choices do not align with the same level of impact or focus on the comprehensive assessment of agricultural extension services in the Philippines. While various missions and programs may have contributed to agricultural development in other ways, the World Bank mission is specifically recognized for its systematic approach to reforming agricultural extension services in the country.
