2.2 Man-made environmental conditions
Employment conditions: Agriculture dependent on pesticides are
generally less labour-demanding than agriculture which do not make use of such
agents. Consequently, information about the extent to which the employment
situation depends on the use of pesticides in agriculture is required. Will
women be especially affected by a prospective change?
In many developing countries, the institutional conditions
connected to plant protection and the use of pesticides are insufficient. Often,
the country lacks an agency which can examine the use and character of the
pesticide in relation to local environmental conditions, as well as institutions
to give official approval to pesticides based on such examinations. Such
institutions are also needed to adjust the directions for use to local
conditions. If such institutions are lacking, one has to rely on information
from other countries. When that is the case, the information should preferably
come from countries with similar climactic conditions. Sufficient knowledge
about chemical pesticides is often lacking. In particular, some users have very
little information about possible environmental impacts and health risks related
to the use of pesticides. Users may in some cases be unable to understand the
directions because of illiteracy. This can be a serious obstacle to the
effective and secure handling of chemical pesticides.
Lack of waste management systems after spraying, can be a
problem in many places. Pesticide waste is classified as hazardous waste, and
requires special handling (see booklet No.11 "Waste management").
The local pollution situation: It is generally assumed that
natural environmental conditions have certain tolerance limits. Certain amounts
of pollution can be absorbed in nature without causing significant changes in
the ecosystem in the area. However, if the tolerance limit is exceeded, the
ecosystem may change so that some species will decline while others will
increase. If one is to estimate the project's prospective risk of exceeding the
tolerance limit, information about the prospective dosages of pesticide is
required, as well as about the extent of annual pollution from other sources in
the area, and the extent of already existing pollution. In addition, one must
decide the acceptable upper limit of pesticide in the drinking water to avoid it
becoming a health hazard for humans and
animals.
