Well before island nations began to consider rising ocean levels, a feature of global climate change (GCC), they have been concerned with the allocation of water resources. The purpose of this chapter is to examine the efforts of universities, in the Tanzanian cities of Zanzibar and Dar-Es-Salaam, to promote environmentally responsible entrepreneurial projects, which sustain women's economic empowerment, while advancing the general development of the broader community, in which they live. The object of this discussion is to examine the history of sea-weed production, and to examine how Zanzibar's seaweed farmers, who are largely women, have responded to adversity, and what, if anything, they can do to address current difficulties.

The study explored global climate change influence on water resources in Yellow River basin. A HBV hydrological model was developed to simulate the rainfall-runoff relationship at the region. Importing the CCLM climate model data, runoff at Lijin station was obtained in 2000-2039. The results indicate: (1) the annual average runoff depth is 1213mm, runoff in summer is larger than in spring,autumn and winter. The water resources decrease in three months (March, April and Jun) and increase in other months. (2) for inter-annual variations, the water resources increases slightly, and increase trend is about 64.8mm/10a. Water resources are insufficient in 200-2016, and rise gradually from 2017. (3) for different decades, the water resources are lack relatively in 2001-2010 and 2011-2020, and the differences are-59.4mm and-76.0mm respectively. While, the water resources in 2021-2030 and 2031-2039 are abundant, and the differences are 90.6mm and 88.8mm respectively.

Lake Kivu

Climate change is emerging as one of the most miscellaneous expressions of the global change nowadays. It potentially affects ecosystems including water resources. The change of climate also has significant impacts on the availability of water, as well as the quality and quantity of water that is available and accessible. Aiming at studying the effect of climate change on water resources, 25 years collected secondary data of both climatic and hydro-meteorological stations were used and Statistical analysis was performed using ORIGIN PRO 8.0 Software. The study linked the surface elevation of Lake Kivu variation with respect to climate change where the level of the lake matches to pluviometric and anomalies values. Finally, the statistical analysis could not directly link the temperature variation with that of surface water level in the lake. Climate change is real and happening now and surely affects water resources among others making an urgent need to control anthropogenic inputs into the atmosphere, one of the factors forcing climate change.

Uncertain Future

The common practices for the planning and management of Water Resources Systems (WSSs) have been challenged in the last few decades by global climate change processes, which are observed around the world in increasing frequencies. Climate change is manifested by climate variability, temperature increase, and extreme events such as droughts and floods, which have a decisive effect on natural resource availability and in turn on water quality. Historical records may not be sufficient to reliably account for uncertain future predictions under climate change conditions. While such highly uncertain situations become the “normal” case worldwide, the traditional practices of probabilistic risk measures cannot be used to appropriately quantify the uncertain phenomena under non-stationarity conditions. To better account for uncertain future conditions, the objective of this study is to develop a water management model based on Info-Gap Decision Theory (IGDT) using optimization under deep uncertainty conditions. The Info-Gap theory is a framework that measures the confidence in the operational decisions by quantifying the robustness to uncertainty without accounting for any probabilistic data. To demonstrate the method as a tool to better guide the long-term sustainable operation of the water supply system under uncertain future conditions, we applied the Info-Gap model to the Sea of Galilee (SoG) regional WSS, which is a significant part of the Israeli National Water System (INWS). For Israel, which is, like other Middle East semi-arid regions, prone to dry conditions and limited water availability, there are well-founded concerns that prolonged periods of drought lie ahead, as a consequence of the global climate change processes. This study contributes a management tool for decision making under deep uncertainty to improve the decision-making process and better adapt to unpredictable uncertain future conditions. We demonstrate how the IGDT could be formulated and used to analyze WSSs under different settings and demonstrate how decisions could be derived from the IGDT formulation. We also show a sensitivity analysis for the obtained solutions.
