In Tanzanian rural areas, chemicals are mostly used as fertilizers and pesticides for improving agricultural productivity. Some of the chemicals and pesticides used are so persistent that they move far and wide, remaining in the environment for decades, with their effects being felt in even the most remote regions. Although the use of these chemicals –especially pesticides- has increased over recent decades, best practices of their management are very often not followed. This has led to significant health and environmental problems, especially for grassroots communities who are the main users.
