“…Sustainability, equity and resource use efficiency in water use planning and policy are main pillars of an Integrated Water Resources Management (IWRM) paradigm [1]. Global Water Partnership [2] defined IWRM as a -process of coordinating development and management of water, land and related resources for maximizing of economic results and social welfare equitably with no compromise on sustainability of environment‖.…”

Abstract:Since irrigation water is assumedly the predominant factor determining crop yield, the difference in irrigation water availability across the administrative sub-districts of the Khorezm region, Central Asia, also inflicts an unequal distribution of agricultural revenues. Considering the national aim of a fair distribution and efficient use of resources, here we analyze the relationships between irrigation water access and rural welfare from 2000 to 2007 by descriptive statistics. Analyses revealed not only the general dependency of agricultural revenue on irrigation water availability, but also occurrence of low land productivity during water scarce years and, irrespective of the annual water availability, in some tail end regions each year. Furthermore, apart from irrigation water availability, land productivity was also impacted by soil quality, cropping structure, and type of land ownership. Fair distribution of water and land resources should also take into consideration population density. It is argued that an anticipated equal and efficient water allocation necessitates improved irrigation water conveyance, distribution, and application efficiency via best water management practices. Liberalization of markets, development of a market infrastructure and improvement in yields also contribute to increased land and water productivity.

“…In this respect, it appears to be necessary to utilise the hydro-hegemonic framework not only for the basin level and between riparian states, but also between different administrational units within one state and how these units share the water resources. For a study on equitable utilisation of water resources between different provinces in Uzbekistan, see Wegerich (2007).…”

The water allocations in the Amu Darya Basin reflect the colonial legacy of the Soviet Union: the downstream riparian states, Turkmenistan and Uzbekistan, were utilized to produce cotton while upstream Tajikistan used water for energy production and it was anticipated to increase its reservoir capacity further to provide water storage and facilitate agricultural production downstream, Afghanistan and Kyrgyzstan were considered simple producers of water without having a real claim to it. Independence manifested inequitable water allocations, giving rise to the perception that especially Uzbekistan is the hydro-hegemon in the Amu Darya Basin. But the post-Soviet basin may be, in fact, without a hydro-hegemon. Data presented in this paper suggest that the riparian states are currently engaged in strategies of resource capture, by increasing their water demand without renegotiating agreements. In addition, while during the Soviet hegemony the increase of reservoir capacity upstream was perceived as 'integration' into the larger framework, today the re-emergence of these plans are perceived as a threat. The analysis of different aspects of hydro-hegemony, such as control over data, current discourses and control over provision infrastructure, demonstrates that Uzbekistan's control over the flows is hardly consolidated.

“…In the context of social welfare, water allocation can be measured by equality of supply/demand proportionately [27]. The proportional approach is largely practiced on irrigation in many countries [28]; it is the provision of water according to individual needs.…”

Limitation and inequality of water in interspace and time opposite to the increased water demand indicated from the density of headwork nodes in the river system. It requires proportional-equal water allocation determined by the model. Existing models are not based on water as a public good and not using the sustainability-efficiency-equity criteria despite irrigation is the biggest use. The Water Allocation Model Equalization or in Indonesian it is called “Model Ekualisasi Alokasi Air” (MEQAA) is proposed. MEQAA modeling system is inspired by the shortage of irrigation water for a quite extended period of time and the complexity of the water allocation system in the Lombok river basin. MEQAA is assisted by MS Excel-VBA 2016 that can be tracked automatically on an independent river system scheme to create a network equation with mass balance principle and operation rule. This model is based on the dynamic-deterministic, so the performance test can be used with synthetic data. This experiment was compared with the output from the equalization method and the “first-come, first-served” (FCFS) method. The conclusions of this experiment are: (a) MEQAA can build a specific model according to a network-flow configuration for optimization-simulation with iteration of K-factor (release portion) and C-factor (storage portion) in order to get a maximum and equal and (b) the FCFS method can be detrimental to the river system. MEQAA is suggested as a decision support tool for water allocation planning or real-time operation.
