Introduction

Conservation Agriculture Sustainable Intensification (CASI) is generalized as a system of sustainable food production from less inputs through more efficient use of resources and with minimal impact on environment. It also implies improving the capacities of people and their institutions to deliver and use inputs efficiently so as to avoid excessive wastage and harness large scale ecosystem services that benefits producers and consumers alike.

Conservation Agriculture is a holistic approach characterized by minimal soil disturbance, diversified crop rotations and surface crop residue retention aimed not only at conserving soil and water but also biotic bases of sustainability. It is a resource saving concept that strives to achieve acceptable profits together with high and sustained production level while concurrently conserving the environment.
