2. Agro-forestry

Combining agriculture with forestry is a solution multiplier: wind velocity is reduced. In summer, the temperature under trees is much lower than in open areas and in winter it is warmer. Just planting individual trees in the fields provides the necessary shade for plants and for livestock. The humidity under trees is also greater than on open sites because of the reduced evaporation and increased water-retention made possible by the improved soil structure. The litter provided by the trees makes excellent fertilizer especially when composted. Forested areas also play an enormous role in preventing floods as the rainfall stored under the forest floor, rendered porous by the tree roots, is released slowly to open spaces and to rivers rather than all at once from otherwise hard deforested land.

The basic objective of promoting agro-forestry is to extract more carbon dioxide, one of the chief environment-damaging gases, from the air and convert it into plant matter - a process technically called carbon sequestration. As such, the advantages of agro-forestry go beyond environment improvement, extending to the conservation of land and amelioration of soil health and its fertility even while keeping the land under agricultural production.
