Deforestation of woodlands in communal areas of Zimbabwe: is it due to agricultural policies?

Deforestation and woodland degradation are iss lies of great concern in Zimbabwe. The debate on these issues has identified a number of causes including expansion of arable land, demand for fuelwood and construction poles, and urban expansion. This paper examined how some policies aimed at improving agricultural production may be contributing to deforestation of woodlands in the communal and resettlement areas of Zimbabwe. Consideration was given to maize (Zen mays L.), cotton (Gosspium hirsutum L.) and sunflower (Helianthus anuus L.); crops with appreciable land area in 1980-90. Regression analysis indicated that policies which improved marketing of grains, provision of credit (largely in form of farm inputs) and extension services, encouraged expansion of land under maize and less so under cotton. High nominal prices encouraged expansion of area under maize while decreasing real prices of cotton, if not reversed, had potential for reducing land under cotton. Increased fertilizer prices, through removal. of subsidies as required by structural adjustment policies, had potential for reducing land under maize and sunflower The driving force for sunflower and cotton production was partly based on the desire, by farmers, fur non-declining revenues in successive years. During the same period, real producer prices for these crops were declining and demand for cash was increasing rapidly. The evaluated agricultural policies appeared to have been responsible for moderate expansion of land area under maize but more significant expansion of land under cotton and sunflower These policies could hare encouraged modest deforestation of woodlands in the Zimbabwean communal and resettlement areas in the period 1980-1995.
