During the past fifty years, agricultural development policies have emphasized the use of external inputs to increase food production to meet population demands. But increased land usage and enhanced global consumption of toxic pesticides and inorganic fertilizers also pose a number of hazardous threats to environmental sustainability. According to FAO, agricultural practices contribute 14%, deforestation and livestock is responsible for around 18% of global green gas emissions.

There is dire need to reduce harmful environmental impacts of agriculture practices on a priority basis. The farming community needs suitable technology to adopt sustainable agriculture practices which are environmentally friendly. In Pakistan, extension agencies can play a vital role by shifting technology and maximizing short-term production outputs to the promotion of practices without negative environmental consequences. We need to strengthen linkages among extension agencies, government environmental departments, environment protecting NGOs and targeted farmer groups for environment conservation efficiently.
