Avoiding Negative Impacts

If it isn't done in the right way, urban agriculture can be harmful. Farming in cities almost disappeared in the 20th century in Europe and in North and South America because of concerns about negative health impacts. Potential problems include irrigation with polluted water, improper handling of animal waste, or the use of chemical insecticides close to schools or other institutions. And converting natural areas into farms is not always good for the ecosystem or for the recreation needs of city populations.

Many cities are now demonstrating that these problems can be addressed with careful planning, effective health and environmental regulations, and the use of new organic farming techniques.
