Appropriate management of our limited resources will be necessary to ensure food security for our growing population and to eliminate poverty. It is imperative to seek a more scientific planning for proper area wise utilization of all the available resources and their sensible management at the State and local level. Agriculture continues to be the most important and largest sector of the Kerala’s economy. Kerala contributes a substantial share to the national economy with respect to four plantation crops viz. rubber, tea, coffee and cardamom. These constitute 29% of the net cropped area. Even though agriculture remains the major contributor to the state’s economy, it has been showing a declining trend both in terms of area under crops and productivity except for Rubber. The most significant changes affecting agriculture are the shrinking of area under food crops, the change in land use pattern and land degradation. The most alarming cause of land degradation includes rapid urbanization leading to conversion of good agricultural lands for other purposes, cultivated lands exposed to indiscriminate use of fertilizers and pesticides, soil erosion and loss of soil microflora and fauna affecting the quality of the soil, etc. Agriculture and environment are inextricably connected. The goal of agricultural policy has been higher production and increased efficiency, but continued increase in production has only been possible through intensification of the farming system which many times involved the clearance of native forests, the introduction of selected or novel crop varieties, increasing use and dependence upon artificial irrigational and chemical aids to soil fertility, crop protection, and food harvest, storage and processing, with a simultaneous increase of pollution risks. Integrating environmental concerns into the Agricultural Policy aims to head off the risks of environmental degradation General Administration, Agriculture and Parliamentary Affairs Department, Government of Kerala, Secretariat, Thiruvananthapuram-695 001 Phone-Office : 2320311, 2518669 Res: 2315656, 2470301 Fax : 2320311 Mobile : 9447744200 e-mail : [email protected] Kerala Environment Congress 2012 Thiruvananthapuram and enhancing the sustainability of agro-ecosystems. What is of great significance is integrating the principles of sustainable development into country policies and programs as well as at local level activities. The scientific community, academicians, experts in the agriculture sector, policy makers, civil society and media has a significant role to play in this context. It is in this context that the Kerala Environment Congress organized by Centre for Environment and Development become highly relevant. The eighth KEC which will be held from 16th to 18th August, 2012 at Thiruvananthapuram aims at highlighting the recent advances in agriculture. The Centre for Environment and Development has once again achieved the distinction of focusing on the linkage of science, technology and the most important aspect of human environment for sustainable development. This Proceedings Volume which contains detailed reviews and papers prepared by eminent experts in the concerned fields related to the focal theme “Agriculture and Environment” will be useful in strengthening the information base of the agencies involved in the agriculture development of the country and the State of Kerala in particular. The inputs from the participants on technologies, processes and societal role in agriculture development and related food security issues offer deeper insight into the issues and thus options for consideration in the State. Information will be helpful in appreciation of relevant facts for formulation of agriculture and environment related policies in a more objective manner.
