Tree-based systems

Tree-based production systems in the Dry Areas of the world are constrained by human-induced degradation, over-grazing, and the increasingly negative impacts of climate change.

In North Africa and West Asia, tree-based systems target rain-fed olive tree cropping with figs, almond, and barley in Jordan and Tunisia, and rainfed wheat production mixed with fruit trees and dairy cattle in Morocco.

In South Asia, researchers and implementing an integrated strategy to promote the sustainable production of trees, crops and livestock as a means of improving the livelihoods of smallholder farmers and generating profitable goods and services.

In the West African Sahel and Dry Savannas the Program is strengthening tree, fruit tree and staple crop-based systems, and adopting both subsistence and market orientations.

Finally, in Central Asia, Dryland Systems researchers are enhancing mixed tree-crop livestock systems, ensuring a supply of firewood, timber, food, and animal feed for local communities.       

Some examples of the work Dryland Systems is doing to strengthen tree-based systems across the Dry Areas: 
Water productivity enhancing technologies are being out-scaled to tree crops such as olives in North Africa and West Asia, generating higher yields and better-quality oil.

Developing and testing value-adding strategies for post-harvest and processing of tree products.
Disseminating knowledge and information on the resilience-enhancing potential of trees in Dryland areas.
