1.1.4. Geology and Soils
Date - 14/Sep/2016
With a gently undulating topography, the district is bound with fresh granite. The main soil types in the District are sandstone, gravel, mudstone, alluviam, granite and shale that have weathered into different soil grades. Due to seasonal erosion, soil types emanating from this phenomenon are sand, clay and laterite ochroslols. The availability of these soil types have contributed to housing development which have resorted to the use of local building materials such as sand, gravel and clay.
These soil types are better suited for the cultivation of cereals and root tuber crops including millet, maize, sorghum and yam. They respond well to the application of organic manure and commercial fertilizers to give high yield. With adequate rains and good farming practices, these soils have the potentials of improving agriculture production.
1.1.5. Environment
The Nandom District has a total of 1515.1 hectares of forest reserves, however, the natural environment of the District has witnessed all kinds of degradation over the years to the extent that the vegetative cover has dwindled and soils have become poor. Widespread bushfires are annual rituals in almost all the communities. Indiscriminate felling of trees for fuel wood (the major source of Energy), inappropriate farming practices, soil erosion, over grazing of livestock, sand, gravel and stone winning are other acts of environmental degradation in the District. Recent efforts by government to institutionalized tree planting in all dry areas of the country and the unique efforts by the District Assembly to complement this policy have come as a relief to help the District fight the increasing pace of desertification.
Table 1: Major Environmental Concerns
No | Nature of concern | Causes | Environmental effects | Poverty interventions |
---|---|---|---|---|
1 | Depletion of wood lots | Bush burning Tree felling | Climate change | Afforestation programs |
2 | Poor soil fertility | Bad farming practices. Bush burning | Climate change Poor quality of underground water Over flooding of river banks | Introduction of new farming techniques. Sensitisation programs |
3 | Land degradation | Sand winning | Climate change | Afforestation |
