A bush fire, which has been lit to clear new ground for planting. When this burning is repeated, year after year, it causes severe soil erosion. - - Agricultural and Social Improvement for Small-Holding Farmers. The ever-growing populations of both rural and urban areas in Ghana need more food, but timeworn agricultural practices are inadequate to the pace of present day needs. Attempts at growing food on already exhausted soil merely results in poor crops, leaving the earth eroded and useless. Farmers, faced with a cycle of crop failures, can barely feed their own families, let alone produce a surplus for market. The government, realizing the urgent need for action, has established agricultural schools for young farmers. When trainees return to their traditional farmlands, extension workers support them during the introduction of soil conservation and anti-erosion techniques; irrigation and improved drinking water supplies; fertilizer use and the growing of new crops. Government family-planning units are also working on the complex problems of over-population. Smaller families and better agricultural methods will eventually bring about a change from subsistence to cash cropping, and thus reduce the country's crippling dependence on food imports. FAO and the UN Fund for Population Activities are among several multilateral agencies providing help.
