Many farm workers cannot read the warning labels about careful use, because they do not know how to read or because the label is in a foreign language. The farmers may be totally unaware of the dangers of handling these chemicals. Often they do not know that they should avoid reusing pesticide containers for food or water.
This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities.
