Title: The Causes and Consequences of Deforestation on Woodlands Production in the Central Clay Plains of the Sudan : A Case Study of Er Renk Area
Author: Onak, Timothy Thwol
Abstract: The case study concerns causes and consequences of deforestation on the central clay plains woodlands production of Er Renk Area (Sudan). It was conducted in the year 2004 and to cover study period: 1983 – 2003. The study aimed at identifying the causes of deforestation, by assessing both ecological and environmental consequences of the phenomenon. It was based on compiled vegetation cover maps and the detection impacts of changes; charcoal production is statistics; annual field crop yields and a selection of climatic parameters. Several methods were used and adopted which included:- 1. An analysis of spatial and temporal data comprising of vegetation cover imageries (TM satellite 1990 and AFRICOVER, 2003). 2. An evaluation of the magnitude of charcoal production within the area. 3. An analysis of climate elements: mean annual rainfall, mean relative humidity, air temperature, and drought indices. 4. An analysis of field crop yield versus climate elements. 5. The questionnaire survey. 6. Statistical Package for Social Sciences (SPSS), was used in the analysis of the woodlands and vegetation cover data , field crop production figures and the climate elements. The major findings were: 1. Existence of wide spread and an unabated deforestation cause mainly by rain fed agricultural production schemes and selectively logged trees for charcoal production. Deforestation 13 was also associated with other anthropogenic and the socioeconomic activities. 2. The inhabitants of Er Renk area were largely an aware of deforestation and it’s consequences, but have limited knowledge about its biophysical implications (vaguely defined in terms of delay in rainfall, reduced annual amount increasing distances of fire wood areas for the residencies and field crops failure). Most of them had no idea about the necessary corrective measure to either halt, reverse, or reduce the impacts of deforestation. 3. The Forests Authorities (NFC, Er Renk) have robust forests development plans, but failed to implement such programme due to lake of funds, inadequate trained to personnel and tools for regular monitoring and protection of the forest. 4. Deforestation was partially responsible for climate variations (drought like features) and subsequent drop in field crop yield during the “ Dry Years”. Amongst other, the important recommendations of the study were:- 1. Re-planting of the old fallow areas with productive three species, imposition of crop rotation and shelter wood belts within the agricultural schemes i.e. to reverse degradation impacts of deforestation. 2. Restrictions be placed on agricultural land leases, charcoal production permits and law enforcement of planting the 10% of agricultural lands with productive tree species such as Acacia species. 14 3. Stepping up the forestry extension service and involving the local community in forest management. 4. Insuring adequate funding by the National Government to Forests Authority (NFC, Er Renk) to provide for foresters training, equipment/Tools acquisition for forest production and its development. 5. Sensitize the Natural Resources Sector to work towards an integrated approach to management i.e. involving foresters, agriculturists, wildlife managers, range and livestock officials, local Government Administration and the community.
