“…It depicts the possible impacts of this ad hoc approach to the water demand-supply system, the environment and subsequently, the long-term survival of the worldrenowned Maasai Mara-Serengeti ecosystem. The simulation results obtained generally conform to other studies elsewhere within the region, such as Mati et al (2008), Olang (2009), Mutiga et al (2010) and Osoro et al (2018). More particularly, however, the following conclusions could be drawn from the present study:…”

This study employed the Water Evaluation and Planning model to evaluate selected policy-based water development and management options on water resources of the upper Mara Basin of Kenya. The major water resources of the region were identified and quantified to establish the current demand versus supply status. Data on domestic water consumption, agricultural demand and industrial consumption were collected through a rigorous fieldwork campaign and used to define the current state of water use and demand. The water resource model was calibrated and validated against observed discharges and subsequently used to simulate the selected policy-based options. Results indicate that an increase between 49% and 180%, depending on the assumed scenario, in annual water demand is expected by the year 2030. As a conclusion, the simulations demonstrate that there is both the need and significant potential to reduce the demand by implementing water conservation measures.

“…The scenario analysis includes an answer to the question (what if). The results of the analysis of the proposed scenarios show the extent of their impact on the reference scenario in improving the management of water resources and choosing the best alternative [4]. The reference scenario has possessed the characteristics of the current conditions with previous methods of water management, taking into account that the population is the urban and rural population, this scenario is useful for comparison with the new scenarios.…”

“…The researchers stressed the importance of managing the available water resources in the most recent ways and means and address this issue in various aspects. Metobwa et al [4] tried to find ways to get rid of the excessive use of water in the Mara River located in Kenya. Sarhan [5] conducted a study of water resources in the Raqqad basin in Syria in order to improve its management.…”

This study aims at developing the aspect of sustainable management of water resources in the part of the upper Euphrates basin to extend the year 2035 by using the Water Evaluation and Planning (WEAP) model. Water budget was developed to assess the current water conditions for the reference year 2015 based on available water supply and the increasing demand for water uses. Some of the proposed scenarios have been applied to the WEAP model. The results showed that the total water demand in 2015 was 100 MCM, and it will rise to 400 MCM in 2035. With the emergence of a water deficit, it is expected that 38 MCM, will be fully provided by applying modern irrigation methods. However, when applying the wastewater reuse scenario, it was found that the water deficit reaches 35 MCM. On the other hand, the water deficit has been approximately decreased to 16 MCM when the groundwater scenario was used as an additional source of water supply. The results confirmed the necessity of adopting alternative methods to reduce the water deficit, as well as the ability of the WEAP model to represent the study area.

“…In previous studies, risks had been quantified to address business risks that faced an event of water stress and had combined the use of satellite imagery, climate data, vulnerability assessments, and other economic indicators for spatially map and quantify risks. Analysis has been done by looking at domestic water needs and water supply (Metobwa et al 2018) where regions with water scarcity or regions facing higher water risks have been mapped basing on these needs. Looking at the various developed water risk indicators, most of them have used indicators such as climate hazards, pollution, population growth aridity, water demand, rainfall variability, groundwater abstraction, and drought.…”

Water resources face risks due to water use stress and water scarcity. Collective and integrated actions by different institutions and stakeholders are needed to reduce future water risks. This paper aimed to assess the potential for a water stewardship partnership in River Nzoia Basin to reduce future water risks facing the ecosystem, agriculture, and other sectors by quantifying water risks and mapping stakeholders for a water stewardship partnership in the basin. Water risks were quantified using indicators from remote sensing platforms and secondary sources. Stakeholder mapping was conducted using stakeholder analysis, while stakeholders' views were collected using questionnaires. The results showed that there is a high fluctuation in the vegetation cover and primary productivity in the basin pointing to a degradation and deforestation. It was also noted that there is an increase in the frequency and severity of drought and high evapotranspiration rates in some parts of the basin due to the low vegetation cover. Combining the results indicated an increase in water risk between 2000 and 2014 in different parts of the basin at a different magnitude of risks. The conducted interviews found that the basin lacked a stewardship program. However, there was a potential for a successful stewardship partnership among stakeholders as most of the stakeholders showed their ability to play a role in the stewardship program. The paper showed a need to form a water stewardship program at the basin to tackle drought, deforestation, and land degradation. The proposed water stewardship program should be built on commitment, transparency, and inclusivity.
