Section
A
The role
of governments in environmental management is difficult but inescapable.
Sometimes, the state tries to manage the resources it owns, and does so badly.
Often, however, governments act in an even more harmful way. They actually
subsidise the exploitation and consumption of natural resources. A whole range
of policies, from farmprice support to protection for coal-mining, do
environmental damage and (often) make no economic sense. Scrapping them offers
a two-fold bonus: a cleaner environment and a more efficient economy. Growth
and environmentalism can actually go hand in hand, if politicians have the
courage to confront the vested interest that subsi-dies create.
Section B
No
activity affects more of the earth’s surface than farming. It shapes a third of
the planet’s land area, not counting Antarctica, and the proportion Is rising.
World food output per head has risen by 4 per cent between the 1970s and 1980s
mainly as a result of increases in yields from land already in cultivation, but
also because more land has been brought under the plough. Higher yields have
been achieved by increased irrigation, better crop breeding, and a doubling in
the use of pesticides and chemical fertilisers in the 1970s and 1980s.
Section C
Section C
All these
activities may have damaging environmental impacts. For example, land clearing
for agriculture is the largest single cause of deforestation; chemical
fertilisers and pesticides may contaminate water supplies; more intensive
farming and the abandonment of fallow periods tend to exacerbate soil erosion;
and the spread of mono-Culture and use of high-yielding varieties of crops have
been accompanied by the disappearance of old varieties of food plants which
might have provided some insurance against pests or diseases in future. Soil
erosion threatens the productivity of land In both rich and poor countries. The
United States, where the most careful measurements have been done, discovered
in 1982 that about one-fifth of its farmtand as losing topsoil at a rate likely
to diminish the soil’s productivity. The country subse-uently embarked upon a
program to convert 11 per cent of its cropped land to meadow or forest. Topsoil
in India and China is vanishing much faster than in America.
Section D
Government
policies have frequently compounded the environmental damage that farming can
cause. In the rich countries, subsidies for growing crops and price supports
for farm output drive up the price of land.The annual value of these subsidies
is immense: about $250 billion, or more than all World Bank lending in the
1980s.To increase the output of crops per acre, a farmer’s easiest option is to
use more of the most readily available inputs: fertilisers and pesticides.
Fertiliser use doubled in Denmark in the period 1960-1985 and increased in The
Netherlands by 150 per cent. The quantity of pesticides applied has risen too;
by 69 per cent In 1975-1984 in Denmark, for example, with a rise of 115 per
cent in the frequency of application in the three years from 1981.
In the
late 1980s and early 1990s some efforts were made to reduce farm subsidies. The
most dramatic example was that of New Zealand, which scrapped most farm support
in 1984. A study of the environmental effects, conducted in 1993, found that
the end of fertiliser subsidies had been followed by a fall in fertiliser use (a fall compounded by the decline in world commodity prices, which
cut farm incomes). The removal of subsidies also stopped
land-clearing and over-stocking, which in the past had been the principal
causes of erosion. Farms began to diversify. The one kind of subsidy whose
removal appeared to have been bad for the environment was the subsidy to manage
soil eroslon.
In less enlightened countries, and in the European Union, the trend has been to reduce rather than eliminate subsidies, and to introduce new payments to encourage farmers to treat their land In environmentally friendlier ways, or to leave it follow. It may sound strange but such payments need to be higher than the existing incentives for farmers to grow food crops. Farmers, however, dislike being paid to do nothing. In several countries they have become interested in the possibility of using fuel produced from crop residues either as a replacement for petrol (as ethanol) or as fuel for power stations (as biomass). Such fuels produce far less carbon dioxide than coal or oil, and absorb carbon dioxide as they grow.They are therefore less likely to contribute to the greenhouse effect. But they die rarely competitive with fossil fuels unless subsidised - and growing them does no less environmental harm than other crops.
Section
E
In poor
countries, governments aggravate other sorts of damage. Subsidies for
pesticides and artificial fertilisers encourage farmers to use greater
quantities than are needed to get the highest economic crop yield. A study by
the International Rice Research Institute Of pesticide use by farmers in South
East Asia found that, with pest-resistant varieties of rice, even moderate
applications of pesticide frequently cost farmers more than they saved.Such
waste puts farmers on a chemical treadmill: bugs and weeds become resis-tant to
poisons, so next year’s poisons must be more lethal. One cost is to human
health, Every year some 10,000 people die from pesticide poisoning, almost all
of them in the developing countries, and another 400,000 become seriously ill.
As for artificial fertilisers, their use world-wide increased by 40 per cent
per unit of farmed land between the mid 1970s and late 1980s, mostly in the
developing countries. Overuse of fertilisers may cause farmers to stop rotating
crops or leaving their land fallow. That, In turn, may make soil erosion worse.
Section F
A result
of the Uruguay Round of world trade negotiations Is likely to be a reduction of
36 percent In the average levels of farm subsidies paid by the rich countries
in 1986-1990. Some of the world’s food production will move from Western Europe
to regions where subsidies are lower or non-existent, such as the former
communist countries and parts of the developing world. Some environmentalists
worry about this outcome. It will be undoubtedly mean more pressure to convert
natural habitat into farmland. But it will also have many desirable
environmental effects. The intensity of farming in the rich world
shoulddecline, and the use of chemical inputs will diminish. Crops are more
likely to be grown p the environments to which they are naturally suited. And
more farmers in poor coun-tries wilt have the money and the incentive to manage
their land in ways that are sustainable in the long run. That is important. To
feed an increasingly hungry world, farmers need every incentive to use their
soil and water effectively and efficiently.
