Changes in cropping pattern, crop pest incidence and type of farming were studied in eighteen west Bengal districts over a long period. Over the last four decades, the survey gave us idea about expansive cropping pattern changes in most of the regions. Majority of the areas are used to produce Rice, Potato, jute, maize, barley and oilseeds under intensive cultivation as per the demand in the local international markets. Therefore in terms of ecological pliability and sustainability, the present production systems is clearly at great work. The crop loss due to individual pests varied significantly. The enormity of losses due to spodoptera, helicoverpa, and aphids impelled farmers to disrupt the present ecosystems with continuous and unnecessary use of pesticides. Canopy openness and shade hacking in the forest-based cardamom agro-ecosystem caused in both micro climate change and amplified infestation by insect pests. Such subtle ecosystems need sufficient soil, crop and insect pest management to achieve the goal of sustainability. It is perceived from the study area that there is a greater differences in the changes in cropping pattern. Farmers have adopted modern technology i.e. fruits and vegetables drip irrigation facility , improved planting technology and micro irrigation systems, good network of transports and markets, agricultural advisory centers and so on. Therefore, recently cropping patterns have been changed to the great extent.
