Nearly one sixth of the global population is malnourished. The problem is particularly acute in tropical Africa, where constant or recurrent food shortages affect over 30% of the population

The Garo, Khasi and Jaintia Hills region, with its unique landscape, climatic phenomenon of heavy cloud cover and torrential rainfall, and agricultural richness involving the majority of the population, has been proposed as another National Agricultural Biodiversity Heritage Site based on six indices.

Traditional farming knowledge on agroecosystem management promoted the low cost sustainable development in ecosystems through optimal use of natural resources. It protects and conserves ecological systems, and improving economic efficiency of the farming community. The coastal agroecosystem of Parangipettai (Portonovo) in Northeastern coastal Tamil

The Oku-Kom highland morphological and human stronghold of West Cameroon with rich volcanic soils has attracted farmers and breeders thereby rupturing the mountain ecological equilibrium through slope gulling and mass movements. Overwhelmed, the indigenes adapted unsuccessful regreening approaches but without slope gradient considerations.

Arunachal Pradesh, being a largest state of Northeast India, harbours great number of plant species which are endemic to region. The diversity and endemism of state has kept it in the category of biodiversity hot-spot. Though, in recent past, numbers of plant species are being listed as rare, endangered and threatened because of increasing threats from anthropogenic and other natural factors.

A survey was conducted in 150 agricultural fields where agroforestry has been followed. Five main multiple plantation patterns of agroforestry systems were followed which includes 2 to 6 plant species.

A 9-year old Hardwickia binata Roxb. plants at a spacing of 5mx5m was intercropped with V. radiata (L.) Wilczek in 2003 to study interactive effects of trees on resource use and crop production.

The present investigation deals with effect of structural composition of agroforestry system, number of woody perennial involved in the sytem and the management of practices plays a major role in influencing the biomass level, carbon storage, CO2 mitigation potential and total carbon sequestration in trees.
