The elevated use of chemical fertilizers and insecticides in crop creation has adversely affected either the surroundings and the rural economic system. not just has it resulted in environmental pollutants, but additionally the expanding expenses of chemical inputs and the low costs obtained for agricultural items have contributed to financial unprofitability and instability. The foreign Symposium on Agricultural Ecology and surroundings was once organised with a purpose to speak about methods of accomplishing the targets of economically and environmentally sustainable agriculture. it's obvious actually multidisciplinary attempt is needed and as a result the assembly was once attended through authors from many alternative disciplines and geographical destinations.

Agroecology should deal with technological issues in such a way that these assume their corresponding roles within a political agenda that in­ corporates social and economic factions in its development strategy. Only pol­ icies and actions derived from the implementation of such a strategy can con­ front the structural and economic factors that determine the agriculturalenvironmental crisis in the ICs and rural poverty in the LDCs. It is therefore the intention of this paper to explore ways in which agroecology can be utilized within a broader rural development agenda that, while improving the technical capabilities of farmers and conserving their resource base, also takes into con­ sideration the impinging social, economic and political constraints.
