“…In this case, we present a river section as a WUS that receives water from upstream (inflows) and supplies water (outflows) to an urban area and an irrigated region while guaranteeing a predefined minimum amount of water for downstream. This example is taken from the Open Access paper of Ahmad and Haie (2018), which analyses the situation of the Kano River in Nigeria (an upper tributary of lake Chad) and the impacts of population growth and climate change until 2050. Here, we describe some general aspects and invite those interested to refer to the paper for more details.…”

This chapter is to help the readers appreciate the wide range of situations that the concepts and tools presented in this book can be employed in order to get a better insight into their functionings. Most of the examples given below are not real case studies with valid data; however, they are mostly adapted from real situations. Furthermore, the exercise is not to present full-fledged cases but rather to link a number of dots for a specific theme and give references for further studies. Finally, to show the input data and the results of Sefficiency, two templates are available: (a) a free MS-Excel tool at Haie (Sefficiency (Sustainable efficiency) of Water-Energy-Food Entangled Systems 2016) as a supplementary document that has the equations and a simple format to simulate various cases side by side, (b) Appendix B: Sefficiency Template is the compact form used for this book.Note In all the tables of this chapter, grey cells display calculated numbers and the underlined numbers are the final solutions or values. Water Saving MythThere is a misconception between water supply/demand and water saving; often thinking that decreasing water supply will save water for downstream users. This may prove to be incorrect due to the law of water balance and the fact that water outflows have two states (FIW2; Sect. 2.4). This myth can be shown through a simple example using the concepts and symbols developed in this book.

“…The elements that were deposited will assist the land become richer or more fruitful after the river water has receded and resumed its usual flow. Therefore, the minerals and organic compounds that the river water deposits help to maintain the soil's fertility and productivity (Ahmad and Tajuri 2018;Shuaibu 2020). When a stream or river reaches an extremely high stage, a flood happens.…”

Frequent occurrence of flash flood is an issue of concern in Nigeria which requires prompt attention. The global worming which triggers the climate change phenomenon is believed to be one of the major causes of flooding. This study reviewed several research works conducted on flood incidences in Nigeria, particularly the Hadejia river valley watershed. The updated and more recent literatures were visited, analyzed and discussed. It was found that for the last decades, there is increasing frequency of flash flood incidences in the study catchment which resulted into displacement of the inhabitants, loss of lives and properties. Substantial portion of the affected places were occupied by people which have been given flood alert and warning previous by climate scientists. Such awareness focused the preparedness and possible relocation in the event of flash flood occurrence. In conclusion, this study has disclosed that there is evidence of increasing rate of flood occurrence at Hadejia river valley catchment. Thus, more effort should be intensified on creating awareness and public enlightenment on how to mitigate the potential damage and loss of life and properties.

“…The linkage between irrigation, poverty, and food security in developing countries had been widely discussed by researchers and policy makers [18][19][20][21]. However, competition for limited water resources and disagreements over water distribution among diverse water users are significant challenges to the sustainability of large-scale irrigation system management across developing countries [22].…”

This study assessed the equity in irrigation water uses and its impacts on paddy yield and water productivity among rice farmers in the Kano River Irrigation Project. Two hundred and twenty-five (225) respondents were used for the data collection from January to June 2021. The data were analyzed using the Kruskal Walli’s test, Tukey kramer post-Hoc test, physical water productivity, and the Logit model. The results indicated that the downstream farmers had the lowest mean yield (1625 kg/acre), lowest access to irrigation water, and lowest irrigation water use (2430 m3/acre). However, they had the highest water productivity (0.66 kg/m3) against 0.44 kg/m3 and 0.58 kg/m3 for middle and upstream farmers, respectively. The logit regression results disclosed that the farm locations, quantity of irrigation water, access to irrigation water, and training on water use were statistically significant determinant of paddy output. Efforts to teach farmers about the actual crop water requirements are needed to promote irrigation water efficiency and conserve scarce resources for other competing users.
