Introduction
The role of trees in environmental security has been well known for ages.
Trees in agroforestry systems not only provide direct benefits (food, fodder, fuelwood, fertilizers, fibres, etc) but also improve soil fertility, reduce soil erosion, filter atmospheric pollutants and most importantly they maintain carbon balance.
Growing multipurpose trees along with agricultural crops, has been considered as a panacea for maladies of intensive agriculture and deforestation…

Agroforestry is practised by millions of farmers worldwide, and has been a feature of agriculture for millennia.
It encompasses a wide range of trees that are grown on farms and in rural landscapes, and includes the generation of science-based tree enterprise opportunities that can be important in the future (1).

Summary
Over the past hundred years, vast areas worldwide have been used for intensive agriculture following clearance by removal of deep rooted tree vegetation or by introducing irrigation in arid zones.
After decades of profitable returns, many of these domains, particularly those underlain with saline aquifers and with poor natural drainage have degraded owing to water logging and salinity.
Disturbed hydrological balance in the form of sustained percolation of surplus surface …
