Title: Assessment of Climate Change Impacts on Wildlife Habitats in Dry lands Sudan -A case of Al Sabaloka Game Reserve
Author: Ali Hassab Elkrim, Ahmed
Abstract: This study was conducted in Al Sabaloka Game reserve, as an established reserve in the dry land ecosystem. It aimed to evaluate the current climatic conditions and trend of change, to determine the current status of wildlife and their habitat in comparison with the previous time, to detect the effects of climate change on the habitat and to assess the wildlife problems in dry lands habitat. The methodology that was adopted in this study has two types of data, namely primary data and secondary data. The primary data involved climatic data for the study area during previous thirty years (1978- 2007), two Landsat satellite images for the years 1987 and 2000, ground assessment data and questionnaire. The sources of secondary data include relevant documents, records and annual reports. The data for the major climatic elements (rainfall, temperature, relative humidity and winds) for the study area were collected and grouped into three periods (1978 – 1987, 1988 – 1997and 1998 – 2007). The data were analyzed by using excel program. The assessment of habitats components (cover, food and water resources) were detected by using both remote sensing techniques and field check using GPS. The Landsat Satellite Images of 1987 and 2000 were analyzed by ERDAS software. Reconnaissance survey and field visits were made firstly then five sampling units (A, B, C, D and E) were selected systematically as the most representative sites of natural vegetation cover. The units were surveyed and checked on ground by GPS and then interpreted in the Satellite images. The ground survey information about the state of wildlife habitats in Al Sabaloka game reserve includes evaluation of trees composition, frequency and coverage, the occurrence and distribution of wild animals and surrounded hazards. The questionnaire was conducted for the local people to compare the past and present status of wildlife in the area and to evaluate the change in the climatic conditions. The results showed that there were fluctuations and changes in the climatic conditions. The habitat was found to be very poor in structure and composition with rare occurrence of wild animals just some reptiles and small mammals. Also many problems were appeared in Al Sabaloka Game reserve such as sand dune movement and desertification, decreasing of natural vegetation and trees cover density and unavailability of grasses and reduction in annual amount of rainfall with the lack of permanent water resources. The above mentioned factors in addition to weak conservation efforts had lead to disappearance of wild animals that used the dry land habitats. VI The study concluded that indices of climatic fluctuations and changes are observed in the area plus some over-exploitation of natural resources. Consequently the habitats were deteriorated, some wild animals were disappeared and some were threatened to extinction. The use of remote sensing technique in detection of land cover degradation as indication for climatic changes is a good tool to be used in dry land habitat such as Al Sabaloka game reserve. Is clear that local people specially village leaders participated in some successful efforts banning for tree cutting and hunting of wild animals in the area. Urgent conservation and protection activities for wild animals and their habitats through the integration approach of management of natural resources is strongly recommended for Al Sabaloka game reserve ,and all similar game reserves in dry lands zones. As a matter of fact Al Sabaloka game reserve is proposed a Biosphere Reserve .The Biosphere Reserve concept calls upon wise conservation and sustainable development of all natural resources and the integration of local communities participation in conservation activities and management plans of the reserve.
