... Sample task type 1 [Note: This is an extract from an Academic Reading passage on the subject of government subsidies to farmers. The text preceding this extract explained how subsidies can lead to activities which cause uneconomical and irreversible changes to the environment.] 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 monoculture 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 19 82 that about one­fifth of its farmland was losing topsoil at a rate likely to diminish the soil's productivity.  The country subsequently 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. 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 19 80s.  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 19 60 19 85 and increased in The Netherlands by 15 0 per cent.  The quantity of pesticides applied has risen too: by 69 per cent in 19 75 19 84 in Denmark, for example, with a rise of 11 5 per cent in the frequency of application in the three years from 19 81.  In the late 19 80s and early 19 90s some efforts were made to reduce farm subsidies.  The most dramatic example was that of New Zealand, which scrapped most farm support in  19 84.  A study of the environmental effects, conducted in 19 93, 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 land­clearing and over­stocking, 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 erosion. ...
