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 improving rural income and employment through promoting and supporting eco-tourism and the management of wildlife, including farming, and encouraging and supporting the husbandry and cultivation of wild species, thus ensuring economic and social benefits without harmful ecological impacts.Excluding communities from managing local renewable resources may lead to mismanagement and abuse of those resources. Awarding its property rights, land tenure and stewardship to the local community can provide strong incentives to manage those resources sustainably. By the same token, communities can benefit from revenues earned if renewable resources are successfully managed. This can be particularly the case with indigenous peoples and other groups with a long "attachment and understanding" to a particular area.
