In order to stimulate interest in reforestation and protection, local needs must first be addressed. Identification of preferred species at the local level, ensures that there will be sufficient care given to sustain the life of the trees. In general, reforestation is popularly accepted when fruit and market producing trees such as timber, poles and fodder were made available, and tenure issues - relevant to tree growth - are being addressed.
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 developing processes to increase the availability of planting materials, particularly indigenous varieties, for use in afforestation and reforestation and to improve sustainable yields from forests.
In Costa Rica communities request not only fruit bearing trees and woodlots, but also for trees for shade and live fences. In Mexico, latex bearing trees are popular for making chewing gum. In Africa, any fruit tree or market-producing tree is welcome and in Asia, communities ask not only for trees, but shrubs and bamboo, as well.
