Climate change impacts on hydrology and water resources of the Upper Blue Nile River Basin, Ethiopia AgEcon
Kim, Ungtae; Kaluarachchi, Jagath J.; Smakhtin, Vladimir U..
The report evaluates the impacts of climate change on the hydrological regime and water resources of the Blue Nile River Basin in Ethiopia. It starts from the construction of the climate change scenarios based on the outcomes of several general circulation models (GCMs), uses a simple hydrological model to convert theses scenarios into runoff, and examines the impacts by means of a set of indices. The results, however uncertain with existing accuracy of climate models, suggest that the region is likely to have the future potential to produce hydropower, increase flow duration, and increase water storage capacity without affecting outflows to the riparian countries in the 2050s.

Crop Performance and Yield of Groundnut, Sesame and Roselle in an Agroforesty Cropping System with Acacia senegal in North Kordofan (Sudan) JARTS
Fadl, Kamal E. M.; Gebauer, Jens.
Crop performance and yield of groundnut (Arachis hypogea), sesame (Sesamum indicum) and roselle (Hibiscus sabdariffa) were investigated in an intercropping system with Acacia senegal and compared with sole cropping. The study was conducted in North Kordofan (Sudan) on loamy sand. Experimental design was a randomized complete block with split plots.Crop performance and crop yield of groundnut, sesame and roselle were significantly (p < 0.05) reduced in the intercropping system compared to sole cropping. However, yield reduction in groundnut (53%) was much higher than in sesame (6%) and roselle (14%). The reduction in yield of the intercropping plots could be due to the high tree density, which results in water and light competition between the trees and...

DEVELOPMENT OF THE AGRICULTURAL CROPS TRADE SECTOR OF SUDAN UNDER THE INCREASING WORLD FOOD PRICES AgEcon
Elgali, Mohamed B.; Mustafa, Rajaa H.; Bauer, Siegfried.
The agricultural trade of the Sudan is expected to develop under the recent dramatic increase of world food prices. Sudan as one of the developing countries and as price taker on the world agricultural market has been affected greatly by the world price increase. This paper aims at studying the impact of the increasing world food prices on developments of the agricultural crops trade sector of Sudan. In this paper a multimarket model is used as the main tool to estimate the increase of the world food prices on the crop trade sector. Multi-market analysis is a tool for simulating the effects of agricultural price policies on outcomes considered of interest to policy makers. The model under consideration takes the normal specification of a standard partial...

Drought and Famine Relationships in Sudan: Policy Implications AgEcon
Teklu, Tesfaye; von Braun, Joachim; Zaki, El Sayed.
Sudan experienced severe food shortage and famine during the 1970s and 1980s. For a country known for its vast agricultural resources, this is both unfortunate and ironic. This research report explores the basic factors that contributed to the recurrence of this phenomenon and identifies policies and actions for avoiding famines and achieving sound and sustainable food policies. The study demonstrates the complexity of policy for prevention, which encompasses macroeconomic reform, promotion of agricultural production and technological change, market development, employment promotion, and interventions for health and nutrition. The researchers extensively investigated all theses aspects from primarily field data gathered before and after the 1984-85...

Economic Incentives for Entry and Exit in Gum Arabic Agroforestry System in Sudan AgEcon
Rahim, Afaf H.; van Ierland, Ekko C.; Wesseler, Justus.
The gum tree (Acacia senegal) in the Sahel-Sudan zone has many environmental benign functions. An important function is to control desertification. In this paper we analyze farmers' economic incentives to preserve the existing gum trees and their incentives to create new plantations using a real options approach. Results indicate that agricultural crops provide higher economic benefits as compared to gum agroforestry system. However, on the one hand, as gum arabic is produced during the dry period and land is abundant, there are low incentives for deforestation. Instead, farmers' tend to leave the land idle and let the tree growing. On the other hand, our results suggest that an increase in the prices of gum arabic of about 330 per cent is needed to induce...

IMPACT OF CLIMATE CHANGE AND INTERNATIONAL PRICES UNCERTAINTY ON THE SUDANESE SORGHUM MARKET: A STOCHASTIC APPROACH AgEcon
Sassi, Maria.
The paper simulates the possible sorghum price change and the related probability of occurrence under different rainfall scenarios and in a context of price uncertainty on international markets. The empirical investigation is based on the stochastic approach. Results underline an expected increase in sorghum price under the effect of the high level of uncertainty in precipitation and in international market price; the most intense likely change produced by the international market price of sorghum uncertainty; the need to overcome the agricultural view in policy making in order to include a market perspective.

Impact of climate change on wheat market and food security in Sudan: stochastic approach and CGE model and CGE Model AgEcon
Sassi, Maria; Cardaci, Alberto.
The paper aims at analysing the impact of the likely change in rainfall on food availability and access to food in Sudan. The empirical investigation is based on an integrated approach consisting of a stochastic method and CGE model. The former provides the likely changes in sorghum, millet and wheat productivity and their probability of occurrence according to rainfall predictions based on historical data. These results are at the basis of the shocks simulated in a standard CGE model augmented with a stochastic component. Achievements underline the negative impact on the two dimensions of food security taken into consideration, mainly due to a reduction in cereal supply, a marked cereal inflation pressure and income contraction; the grater negative effect...

Implications of a Doha Agreement on Agricultural Markets in Sudan AgEcon
Abdel Karim, Imad Eldin Elfadil; Abler, David G..
The latest round of multilateral trade negotiations was launched at the ministerial meeting of the World Trade Organization in Doha, Qatar, in November 2001. Agriculture is a major item on the agenda for the Doha Round. The primary focus is on the three “pillars” of the Uruguay Round agreement—domestic support, market access, and export competition. The framework for a final agreement was finalized at a Ministerial meeting in Geneva in July 2004, but contains few details on modalities (e.g., the formula to be used for reductions in tariffs/increases in tariff-rate quotas, quantitative limitations on domestic support, and the schedule for the elimination of export subsidies). Detailed proposals on a number of these issues were put forward in October 2005...

Managing Conflict Over Natural Resources in Greater Kordofan, Sudan: Some Recurrent Patterns and Governance Implications AgEcon
Siddig, El Fatih Ali; El-Harizi, Khalid; Prato, Bettina.
Despite the 2005 Comprehensive Peace Agreement, which brought to an end 20 years of civil war in the Sudan, this country continues to experience smaller-scale conflicts, particularly around access to and control of natural resources. Some observers lay the blame for this on ethnopolitical or tribal divisions. However, this paper argues that there are a variety of factors at play behind these conflicts, notably the combination of resource scarcity with a crisis of governance that is particularly evident in transitional areas like the Kordofan region. To gain a sense of the range of conflicts around natural resources in Kordofan, the authors reviewed existing records such as government archives; conducted interviews with politicians, federal and state...

Measuring and Accounting for Community Capabilities in Kordofan, Sudan AgEcon
El-Harizi, Khalid; Klemick, Heather.
Parallel to the growing attention being devoted to the relationship between empowerment and development, an increasing number of tools are being developed to measure empowerment and determine the link between these two phenomena. This paper details the methodological processes used to construct, test and possibly refine one such instrument, the Community Capability Index, an innovative tool to measure community capabilities in the domain of natural resource governance. Empirical reference is made to research conducted in 85 villages in North and South Kordofan, Sudan. Following this, the paper presents findings from analyses of the determinants of community capabilities, including geographic, economic, and institutional variables. The results suggest that...

Oil and Agriculture in the Post-Separation Sudan AgEcon
Siddig, Khalid H.A..
The Comprehensive Peace Agreement (CPA), which was signed by the government of Sudan and the Sudanese People’s Liberation Movement (SPLM) ended more than 20 years of civil war. According to the CPA, the Sudan’s government has 50% of the oil exploited from the wells existing in the south in addition to the oil produced from the northern wells. The latter represents about 30% of the total oil production in Sudan. In January 2011, the people in southern Sudan have voted for separation from the Sudan and in July 2011 the Republic of South Sudan was officially announced as Africa’s newest state. Now the CPA period is over and the south possesses its entire production of oil, but need to use the export infrastructure that exists in the north to export it. For...

Spatial price transmission: A study of sheep markets in Sudan AgEcon
Babiker, Babiker Idris; Abdalla, Abdel Gabbar M..
Recent research in low-income countries has shown that high transfer costs and marketing margins may hinder the transmission of price signals, as they may prohibit arbitrage. Oligopolistic behavior and collusion among domestic traders may retain price differences between markets at levels higher than those determined by transfer costs and hinder the full price transmission and market integration (Rapsomanikis et al., 2003). This paper investigates price movements among important sheep markets in the Sudan to explore their performance and pricing efficiency. Six geographically separated livestock wholesale markets are tested spatially, using Johansen’s cointegration test (1988) and time-series price data for the period 1990–2004. Spatial analysis of the...

The Controversy of Exchange Rate Devaluation in Sudan: An Economy-wide General Equilibrium Assessment AgEcon
Siddig, Khalid H.A..
The international Monitory Fund (IMF) has been working with Sudan since 1997 to implement macroeconomic reforms including a managed float of the exchange rate (EXR). The IMF sees the EXR flexibility as key to safeguard and rebuild foreign exchange reserves and essential to meet the international reserve target in Sudan. However, the authorities in Sudan are concerned that greater exchange rate flexibility could contribute to inflationary pressures. In addition, a review of literature focusing on the exchange rate policies in Sudan reflects huge ambiguity about its outcome. This calls for additional empirical investigations that provide economy wide assessments of the various possible scenarios that could be adopted in the Sudanese context. Accordingly,...

The Engendered Spaces in the Village at the Edge of the Capital: A Case Study of Al Gharaza/Sudan AgEcon
Badri, Balghis; Knuth, Hardine.
This research is the outcome of fieldwork undertaken between November 2002 and 2003 in Al Gharaza village part of Khartoum State - the Sudan capital. The study focuses on identifying how spaces and times are interrelated and engendered. The forces that impact the creation of boundaries or those that direct change are analysed. How women’s boundaries and spaces are defined and their interaction with them and bringing about new arrangements for spaces is discussed. How time is used, division of labour engendered, time conceptualized are highlighted. It is found that tradition and customs of exclusiveness as a value create a siege binding women spaces within the village and impact on their use of time: education is an important force that manages to crack the...

Trypanosoma vivax is the second leading cause of camel trypanosomosis in Sudan after Trypanosoma evansi OAK
Mossaad, Ehab; Salim, Bashir; Suganuma, Keisuke; Musinguzi, Peter; Hassan, Mohammed A.; Elamin, E. A.; Mohammed, G. E.; Bakhiet, Amel O.; Xuan, Xuenan; Satti, Rawan A.; Inoue, Noboru.
Background: This study was conducted in response to recurring reports from eastern Sudan of camel trypanosomosis that can no longer be treated by currently available trypanocidal drugs. One hundred and eighty-nine blood samples were obtained from camels in different herds and local markets in the western part of Sudan, and a cross-sectional study was carried out between December 2015 and February 2016 to identify the causative agents and possible circulating genotypes. Results: The prevalence of trypanosomes detected using the conventional parasitological techniques of Giemsa-stained blood smears, wet blood smears and the microhematocrit centrifugation technique (MHCT) was 7% (13/189), 11% (21/189) and 19% (36/189), respectively. However, a multi-species...

Understanding Policy Volatility in Sudan AgEcon
El-Harizi, Khalid; Zaki, El Sayed; Prato, Bettina.
In this paper we present the findings of a qualitative investigation into some dimensions and implications of policy volatility in the realms of natural resource (NR) governance and devolution in contemporary Sudan, with particular reference to Greater Kordofan. Our goal is to map out some aspects of the interplay between volatility, disempowerment processes affecting both state agents and the rural population, and certain problems of governance that are characteristic but not unique to Sudan. In particular, we argue that volatility is a dimension of poor governance worthy of investigation in its own right, as it is a primary ingredient of what we may call a “self-disempowering state,” where adaptive learning in policy processes is impeded and successful...
