The document discusses manpower development and training needs for sustainable irrigation in Nigeria. It notes that while Nigeria has invested heavily in irrigation projects, many large projects have been disappointing due to a lack of properly trained staff. There is an acute shortage of suitably trained manpower to operate irrigation schemes. The document calls for establishing an effective training framework, assessing needs, and providing various forms of training to scheme officials and farmers to improve management of irrigation resources and productivity. This includes classroom, field, and workshop training on topics such as project management, extension services, technology transfer, and entrepreneurship.
