“…There are many criteria for water allocation depending on a situation. Among the many criteria, the economic and ecological benefits also take a significant role [24], [25]. A discussion among water professionals engaged in water allocation between different water users revealed that most frequently considered criteria are the nature of use such as essential or non-essential, the number of users, the spatial coverage, and consumptive or nonconsumptive use.…”

In Sri Lanka, over 30 national institutions compete to obtain access and priority to use water to perform a variety of water service delivery functions. Water sharing problems have created many conflicts among stakeholders. Presently, there is a lack of transparent and verified models for the assessment of water availability, demand and perform water allocation. It appears that the current practice based on weak information combined with stakeholder judgement is considered as acceptable mainly because of the absence of a water policy and regulatory system. The objective of the present work is to perform a multi criteria assessment to compare the priority of water allocation based on the judgement of water experts and then to evaluate the adequacy of same to evaluate the need to establish a comprehensive water policy. Five multi criteria modelling options based on stakeholder perceptions from 11 water user institutions were compared with the order of magnitude of present water use. Available water was first prioritised using the model weights and then reallocated to the three top ranked water users by considering their annual water use. Multi criteria water allocation models with consistent parameters could be developed by using stakeholder perceptions and rational assumptions. Comparative evaluation of model outputs and the order of magnitude water use data showed that any attempts to use stakeholder consultation with water allocation models must be well supported with transparent and verified water availability and demand assessments. Demonstrating that water allocation based on stakeholder opinion alone is not satisfactory, the present work points to the urgent need for Sri Lanka to seek a comprehensive water policy, rules and regulations.

“…It is worth noting that more criteria could be defined; however, selected indicators should reflect the main characteristics of the problem identified in the study area, and they should be computable with the available data. It is also clear that these indicators are used to measure the performance of decision options; therefore, they should be relevant to the decision maker's objectives [44].…”

One of the main causes of water conflicts in transboundary watersheds all over the world is represented by the increasing water demand due to urban, industrial, and agricultural development. In this context, water scarcity plays a critical role since, during a drought period, water supply is not sufficient to cover the demand of all water uses. In this work, we have conceptualized and developed a new scenario-based framework able to improve the sustainability and equity of water allocation among two or more riparian countries. The proposed approach is in accordance with the United Nations Watercourses Convention. It considers a hydraulic/hydrologic model, a water-management model, and combines them with multi-criteria decision analysis (MCDA) and what if scenario analysis (WISA). The suggested framework was applied to the transboundary watershed of Cuareim/Quaraí river (Uruguay/Brazil) to tackle a real water-sharing conflict. It resulted in being very flexible in exploring various policy options and test and quantifying them with different scenarios to reach an objective and impartial decision in a water-sharing issue. This framework can effectively be applied to any other transboundary watershed to resolve any possible conflict related to water-allocation/water-management matter.

“…Water scarcity is one of the major challenges facing the world today [1][2][3][4][5][6]. UN-Water defines water scarcity as either physical water shortage or inaccessibility caused by failed water supply systems or inadequate water infrastructures [3].…”

The Kenyan government has made significant advances in water resources management at the local authority (county) level with little or no cooperation at the drainage basin level. Research on critical determinants of cooperation amongst transboundary water negotiation teams is limited. In this paper, we assess whether personal attribute diversity (PAD) is a stronger factor than demographic diversity (gender, age, and education play) in determining whether the negotiation team will cooperate or make unilateral actions. We use a negotiation game to study decisions taken by water policymakers. After that, we conduct a multiple discriminant analysis (MDA) to assess the influence of PAD, gender, age, and education on water negotiation outcomes. The findings indicate that PAD plays a significant role in determining whether the group will cooperate or compete. Gender, education, and age barely influence the outcome. Only upon removal of the PAD variable do we see an increase in the discriminant power of gender and education. Age has minimal influence on the negotiation outcomes. We apply the research at a lower level of governance (Nzoia River Basin). However, results might be extrapolated to a bigger basin, like the Nile Basin, through future multiple level analysis which takes account of the complex socio-technical systems.
