In emerging East Asia, agricultural output has expanded
dramatically over recent decades, primarily as a result of
successful efforts to stimulate yield growth. This achievement has
increased the availability of food and raw materials in the region,
drastically diminished hunger, and more generally provided solid
ground for economic development. The intensification of agriculture
that has made this possible, however, has also led to serious
pollution problems that have adversely affected human and ecosystem
health, as well as the productivity of agriculture itself. In the
region that currently owes the largest proportion of deaths to the
environment, agriculture is often portrayed as a victim of
industrial and urban pollution, and this is indeed the case. Yet
agriculture is taking a growing toll on economic resources and
sometimes becoming a victim of its own success. In parts of China,
Vietnam, and the Philippines - the countries studied in The
Challenge of Agricultural Pollution - this pattern of highly
productive yet highly polluting agriculture has been unfolding with
consequences that remain poorly understood. With large numbers of
pollutants and sources, agricultural pollution is often undetected
and unmeasured. When assessments do occur, they tend to take place
within technical silos, and so the different ecological and
socioeconomic risks are seldom considered as a whole, while some
escape study entirely. However, when agricultural pollution is
considered in its entirety, both the significance of its impacts
and the relative neglect of them become clear. Meanwhile, growing
recognition that a "pollute now, treat later" approach is
unsustainable - from both a human health and an agroindustry
perspective - has led public and private sector actors to seek
solutions to this problem. Yet public intervention has tended to be
more reactive than preventive and often inadequate in scale. In
some instances, the implementation of sound pollution control
programs has also been confronted with incentive structures that do
not rank environmental outcomes prominently. Significant potential
does exist, however, to reduce the footprint of farms through
existing technical solutions, and with adequate and well-crafted
government support, its realization is well within reach.
