Other extension services, such as farmers' organizations, cooperatives, enterprise associations, drought observatories and weather stations, need to be strengthened through greater funding and manpower allotments, or public private partnerships. Most importantly, organisations must be equipped with the capacities to address the economic, social and environmental impacts on agriculture and the affected communities through participatory approaches that involve civil society, local communities, indigenous people and other major stakeholders, including in particular women who are often marginalized in decision-making and policy formulation. For example, the evaluation of post-harvest technologies is best undertaken with the participation of stakeholders and the introduction and operation of a fair and practical grading system that must be supported by training and extension to improve handling, storage and packing, sorting and grading practices.
