Development of agroforestry model using water harvesting system in semi arid and arid zones
Bashir Hussain Shah
ABSTRACT
A study was conducted at Kharian to develop an
agroforestry system by using water harvestging system in
semiarid zone. Twop slope lengths: 4m and 5 m and three
slope gradients: 7%, 10% and 15% of roaded catchments
were tested for finding out optimum slope length and
gradient for water resource development to increase crop
and wood production. Results of the study showed that
four meter slope length with 7% gradient are more
effective in increasing the runoff and are economical to
construct and maintain. It was also observed that water
production to cropping area ratio at Kharian should be
1:2. The study indicated that crop production can be
enhanced by 40% and tree growth can be increased by
three times by using the water harvesting system.
