This publication presents the outcomes of initiatives promoting climate-smart agricultural practices and technologies in Bangladesh, Cambodia, and Nepal. It emphasizes learnings from a technical assistance project that aimed to (i) identify constraints on and support for scaling up water-saving mechanized technologies; (ii) demonstrate agricultural practices that can improve crop productivity, resilience, and adaptive capacity; and (iii) develop databases to capture survey, on-station, and participatory trial data. The publication is intended to aid succeeding efforts on bringing science-based and participatory solutions that can address the needs of rice-farming communities in the three countries.
