Pesticide Use in Swat Valley, Pakistan Exploring Remedial Measures to Mitigate Environmental and Socioeconomic Impacts

摘要

Pesticides are increasingly used in Pakistan, including in remote Northern areas in the country, for several reasons. A study in Swat Valley investigated the use of pesticides and associated problems, and identified possible remedial measures of an indigenous nature. Soil samples were analyzed and a detailed survey was done in 12 villages, based on interviews with 216 farmers and several in-depth interviews with other stakeholders such as the agriculture department and various pesticide dealers. All the soil samples contained residues of pesticides, 2 of which are known to be highly toxic and accumulate in nature. Thus they represent a potential risk to the health of people and the ecosystem. The various factors contributing to heavy pesticide use include adulteration and the unscientific way pesticides are used, which in turn affects apiculture and populations of fish and migratory birds. Therefore, proper awareness and farmer training may be helpful to avoid use of pesticides, including for fishing, while administrative measures should be adopted against adulteration. Pesticide use can also be minimized by crop rotation, early harvesting, and reviving farmers' collective work system in farmer field schools (FFS).
