Imad-Eldin A. Ali-Babiker, Faisal M. El-Hag, Abass E. M. Elamin, Bashir A. Eltahir and Abdelmotlib A. Ibnoof

Abstract

This study was designed to assess involvement of researchers in climate change adaptation and their capacity to generate scientific evidence on climate change adaptation policies and plans of action. Information used for conducting study included both primary and secondary data. An inventory of research scientists working in climate change in agriculture and water resources including animal agriculture was made. The study showed a clear indication of limited scientific evidence on climate change impact assessment both in water resources and animal agriculture. Only 15.4% of the research programs (4 out of 26) had elements of climate change impact assessment on animal agriculture and water resources... Read more

Eleven villages (18655 households) were surveyed. About 97% of the respondents suffered from water scarcity, with 51% stating surface water depletion especially during summer when temperatures were high and rainfall was low... Read more

Vulnerability and Potential Adaptation Options of Agricultural Sector to Climate Change in Sudan

Abdelrahman K. Osman

Abstract

Agriculture is the main sector of the Sudan’s economy and it is the major livelihood source for more than 70% of the population. Agriculture has been identified as one of the three highest priority sectors most vulnerable to climate change. Several recent studies have indicated the substantial decline in precipitation and rising in temperature in several parts of the country. Current and potential impacts of climate change include reduction in yields and duration of crop period, increased occurrence of dry spells, warm and too short winter, land degradation, increased water requirements and decrease in water availability, increased occurrence of dust storms and sand blast, and socio economic impacts...

Evaluation of Climate Change Effects on the Growing Season in Butana Region and North Kordofan, Sudan

Abdelrahman A. Khatir, Abdelmalik M. Abdelmalik, Mawada G. Abdalla, Sarah A. M. Elmobark, Imad-eldin A. Babiker, Sara A. Babiker and Faisal M. El-Hag

Abstract

This study applied remote sensing to evaluate the effects of climate changes on growing season in different agro-ecological zones, in North Kordofan and Butana region, Sudan, for the period 2001-2011. NDVI data were used for the NDVI time series and phenological analysis. Within the semidesert zone in Butana region, the trend for the starting date of the growing season was stable, while that for the end of the season indicated a shift to an earlier date, resulting in shorter growing season (av. 80 days)...

Three States; Gadarif, Gezira and Khartoum states, out of five states constituting Butana region were chosen... Read more

Managing Rainfall Variability in Arid Rainfed Agriculture Using Adaptive Varieties and In-situ Water Harvesting

Kawkab E. Babiker, Abdelhadi A. W. Mohamed, Imad-eldin A. Ali-Babiker
and Hussni O. Mohammed

Abstract

This investigation was to establish a water harvesting technique for adaptation to rainfall variability in rainfed sorghum production and relate it to yield in Gedarif area. A field experiment was conducted for two successive seasons (2009-2010). A split-split plot design was used to test the hypothesis that crop yield was affected by three methods of sowing representing in-situ water harvesting techniques, namely; wide level disc in rows 80 cm apart using row planter and at bottom of ridges 80 cm. Three sorghum varieties were used, Arfa Gadamak8, Wad Ahmed and Bashaer... Read more

Impacts of Climate Change on Biodiversity in Sudan: A Review

Ahmed S. El Wakeel

Abstract

The Central Bureau of Statistics in 2008 classified the population of Sudan into rural (67%) and urban (33%) categories. The pastoral group of the population has been added to the rural category. This implies that most of Sudan’s population secures their livelihood by using natural resources. This situation has put intensive pressure on these resources, and has thereby led to serious degradation in biodiversity and the rest of ecosystems components... Read more

Impact of Climate Change on Natural Resources at EL-Damazine and AT -Tamadon Localities, Blue Nile State, Sudan: Biodiversity perspective

Hanadi I. O. Babikir and Muna M.M. Ahmed

Abstract

The present study aimed at detecting climatic changes impacts on natural vegetation at the two localities of El-Damazine and Al-Tamadon, Blue Nile State, Sudan, during 2010-2011. Remote sensing techniques were used for depicting changes in vegetation for the years 1972-2011. Descriptive statistics were used for data analyses using SPSS (Ver. 16). Fluctuations in rainfall through the years (from 1972 to 2011) reflected a general declining pattern while that of temperature tended to increase... Read more

Coping strategies to water shortages in central Sudan: Almanagil locality

Hussein S. Adam

Abstract

The total irrigated area in Sudan is about 1.7 Million ha. Half of it is in the great Gezira scheme, which is taken as an example to discuss the effect of climate change on irrigation. Climate change is a reality. The increase in global temperature as a direct result of the increase in CO2 is evident. The increase in temperature leads to a 5% increase in crop water requirements which amounts to 800 million m³ in Gezira scheme... Read more

Jonas Ardö

Abstract

Climate change poses risk for natural and human systems in Africa. Increasing temperatures and changes in precipitation patterns is likely to affect agriculture, pastoralism and forestry. Mitigation of increasing atmospheric concentration of CO2 through soil carbon sequestration in semi-arid ecosystems may be beneficial to soil properties and cultivation... Read more

Climate Change Adaptation through Sustainable Forest Management in Sudan: Needs to Qualify Agroforestry Application

Bashir A. El Tahir

Abstract

Global warming as a result of climate change will bring major changes in rainfall and temperatures throughout the world, affecting the livelihoods of many rural and urban populations. Sudan encompasses the largest dry lands in Africa, equal to over 92.1% of the total area of the country, where 82% of the population lives. Predicted changes in temperature and rainfall amount and distribution induced by climate change will have major impacts on the natural environment (soils, water, and vegetation) on which people and their livestock depend...
