“…The irrigation networks in the Gezira scheme are in a state of disrepair and maintenance is often deferred due to inadequate funding (World Bank, 2000). Water is not delivered to the farms in a timely manner, causing low yields and low farm incomes (Abdelgalil and Adeeb, 2015). A large proportion of farmers are unwilling to pay water charges, although that is a small fraction of the crop production cost (World Bank, 2000).…”

Several factors contribute to poor irrigation management. A set of natural, social, environmental, institutional and technological variables can collectively result in complex and messy problems. Traditional engineering systems are not well suited for addressing coupled and interlinked types of problem. To this end, a hybrid network model is introduced to study the cumulative impact of these variables on the performance of irrigation projects. The model is based on the theory of complex adaptive systems and agent-based modelling. The Gezira scheme in Sudan is used as a case study in order to convert the vicious circle through adopting an improved and most viable irrigation management system. Six key variables are selected as dominant driving forces that influence the performance of the irrigation scheme. These are scheme governance, agricultural research, agricultural inputs and technologies, farmers, water user associations and the irrigation agency responsible for operation and maintenance. The scope of the analysis is to explore the dynamics of system enhancement under different scenarios of policy intervention. The results revealed the need for balanced and diversified investment in all entities to ensure sustainable growth. The findings emphasize the importance of having interventions with moderate growth patterns that seek to enhance cooperation and positive feedback among entities.

“…There is a large volume of published studies describing the performance of water management in the Gezira scheme from different perspectives [12,[15][16][17][18][19][20][21]. In spite of the wide range of topics covered by these studies, however, to the best of authors' knowledge, there is no deep analysis for the organizational role and its impact on the performance of irrigation systems.…”

This study aims to offer a comprehensive assessment of the impacts of policies and institutional arrangements on irrigation management performance. The case study, the Gezira Scheme, has witnessed a significant decrease in water management performance during recent decades. This situation led to several institutional changes in order to put the system on the right path. The main organizations involved in water management at the scheme are the Ministry of Irrigation & Water Resources (MOIWR), the Sudan Gezira Board (SGB), and the Water Users Associations (WUAs). Different combinations from these organizations were founded to manage the irrigation system. The evaluation of these organizations is based on the data of water supply and cultivated areas from 1970 to 2015. The measured data were compared with two methods: the empirical water order method (Indent) that considers the design criteria of the scheme, and the Crop Water Requirement (CWR) method. Results show that the MOIWR period was the most efficient era, with an average water surplus of 12% compared with the Indent value, while the most critical period (SGB & WUAs) occurred when the water supply increased by 80%. The other periods of the Irrigation Water Corporation (IWC), (SGB & MOIWR), and (WUAs & MOIWR) had witnessed an increase in water supply by 29%, 63%, and 67% respectively. Through these institutional changes, the percentage of excessive water supply jumped from 12% to 80%. Finally, the study provides general recommendations associated with institutional arrangements and policy adoption to improve irrigation system performance.

“…The authors identify a possibility to capitalise more profitable the natural resources from Dobrudja Plateau area by the reconsideration of the culture structure, respective the eventuality of extending the cultivated surfaces with grain sorghum -Sorghum bicolor (syn. Sorghum vulgare), for its use in the producing of biofuel (Abdelgalil and Adeeb, 2015).…”

In this paper are presented studies regarding the identification of some solutions -an alternative to the fuel world crisis, respective obtaining biofuels from grain sorghum crop (Sorghum bicolor L. Moench). In Romania, the cultivated surfaces are quite small, comparative with the existing agro-climatic potential. The authors identified, following the researches, a pedo-climatic area from Romania, respective Dobrudja, where the grain sorghum meets agro-pedo-meteorological conditions favourable to obtaining of high yields. It was analysed the grain sorghum crop in the world, in Europe and Romania, but also two cultures of grain sorghum, one under field conditions and the other one under experimental conditions in the teaching plot belonging to the Ovidius University from Constanta. There are presented the results obtained regarding the technology elements applied to this culture, as well as observations upon the infestation with diseases, pests attack and the frequency of the weed species in grain sorghum crop.Keywords: solutions -alternative; biofuel; sorghum crop; agro-pedo-meteoclimatic conditions; weeds; diseases; pests; culture analysis.
