the importance of agroforestry in the environment and sustainable development of society
The increased pressure on the world natural resources which arises from population growth as well as economic pressure has resulted in unsustainable use of natural resources and environmental instability. The unstable nature of the world climate, attributed to human activities, depletion of forest cover due to increased hunger for forest and non-forest products has caused a lot of environmental problems such as, land erosion, flooding, frequent and severe storm, depletion of soil fertility, natural disaster as well as seasonal changes of world climate: These negative effect on the world ecosystem required a crucial attention that is agroforestry
Agroforestry is a means of halting the vicious circle of deforestation, soil erosion and other environmental problems facing the country. Agroforestry refers to the combination of agriculture and forestry practices within a farming system
For example, in northern Tanzania, especially for the people, the Chagga people are practicing a hybrid farming system where various trees and crops such as bananas, maize, beans and coffee are grown together.
This system has various benefits such as access to adequate food, commercial crops such as coffee are used to increase family income, environmental protection and soil fertility, three leading to protection from crop damage by pests and strong winds, also leading to access to energy and rain from trees
