Rural financial markets in developing countries have inherent problems that make investments risky and costly: clients are to scattered, rural clients all want to borrow at the same time (in the pre-harvest season) and to save immediately after the harvest, and the poor own few assets to secure loans. Private sector financial institutions are reluctant to take on these risks.This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities. Agenda 21 recommends promoting and improving rural financial networks that utilize investment capital resources raised locally.
