PREFACE
To-day there is a growing realization that for sustaining agriculture production, a dialectical approach is needed. It has to be comprehensive, integrating efficient use of all the inputs with a sustained natural resource base. Considering the ecological niches for each production system is important. Besides the natural resources, the human resource warrants adequate consideration, more so the ecologically and economically disadvantaged communities. High yielding varieties, hybrids, GM crops and the present nanotechnology can express their potential only when the natural resources are in their pristine glory. To-day they are degraded. There is an ecological crisis. All of us must first correct this malady for enhancing the productivity in agriculture. Thus soil health needs active attention. The soils must be brought out of sterility to living conditions. This is all the more so with the global warming and the consequences thereof. The costs in production of crops and livestock based products is ever increasing. Labour costs are on the rise. We have to make all out efforts to produce more at reduced costs. Today the farmer has to depend on other agencies for seed, nutrients, pesticides and water management. He has to be brought back from dependence to independence. This can be possible by internalizing the production system. Ecological farming is the solution. It not only reduces the cost in production, but also becomes an agent in cooling the climate. It acts as an ecological protection service. So we plead ecological farming needs the support of the Government for evolving sustainable production leading to a cooler climate and a healthier NATION.
