The purpose of this research was to understand the carrying capacity of Kayan and Sembakung watershed in North Borneo Province, the carrying capacity in providing clean water and how was the trend of the carrying capacity of the water supply in the Kayan and Sembakung watersheds, which were the basis for food supply. The study area was the Kayan and Sembakung watersheds in the administrative area of North Kalimantan Province using an “ecosystem services” approach. The results of the research were as follows: (1) the Kayan and Sembakung watersheds in North Kalimantan Province were dominated by areas that have “high” carrying capacity in providing food; (2) The Kayan Watershed in North Kalimantan Province was dominated by areas that have a “moderate” environmental carrying capacity in water supply, while for the Sembakung watershed it was dominated by areas that have a “high” environmental carrying capacity in water supply; and (3) The carrying capacity of the downstream areas of the Kayan and Sembakung watersheds in the provision of clean water tended to be “Very Low” when the carrying capacity of the downstream ecosystems in the Kayan and Sembakung watersheds as food providers was “High”.

In order to comprehensively evaluate the water resources carrying capacity in Xiong’an New Area, a system dynamics (SD) model was established to evaluate the regional water resources carrying capacity, for which several scenarios were designed: the original development scenario, the accelerated industrialization scenario, the environmental governance scenario, and the optimization development scenario. The results show that, compared with the original development scenario, the water resources carrying capacity in Xiong’an New Area can be improved in other scenarios, but a water supply and demand gap will be generated due to the lack of groundwater overdraft and a water transfer project. In 2026, under the accelerated industrialization scenario, the population carrying capacity will be 2.652 million, and the water supply and demand gap will be 1.13 × 108 m3; under the environmental governance scenario, the population carrying capacity will be 2.36 million, and the water supply and demand gap will be 0.44 × 108 m3; under the optimal development scenario, the population carrying capacity will be 2.654 million, and since the supply of water resources will be greater than the demand, there will not be a gap between supply and demand, making it the most feasible scenario to effectively alleviate the tension between industry restructuring, environmental management, and water resources development and utilization. The findings of this study can provide reference and decision support for optimizing regional water resources allocation and enhancing water resources carrying capacity in Xiong’an New Area.

Lowland river water power developments are usually built to solve complex tasks on the basis of the requirements of rational use of water resources. First of all, operating conditions of hydroelectric complex structures should provide safety and economic efficiency in their work. Besides, they are aimed to satisfy various demands of water consumers. It is particularly important that behaviour of hydroelectric complex structures should satisfy contemporary requirements of environmental security. The most important task here is to create favourable ecological conditions of life for people who live in settlements located in the zone of influence of two hydroelectric complexes located on different rivers. Here, to achieve environmental targets it is necessary to interlink modes of operation of these water storage control structures. There are two water power developments built in the Republic of Bashkortostan, Russia, in the middle flow of the Belaya River. Both of them have considerable impact on the formation of level mode and different consumers’ water supply. They are Umaguzinskiy and Nugushskiy water power developments. Both hydroelectric complexes and their water reservoirs together satisfy the following generally accepted requirements of water consumers: - they prevent the lowering of the water level in the river Belaya (during low streamflow period) below the minimum values required to ensure proper water supply for industrial enterprises; - they generate electric power and provide industries and cities with electricity. To do that each water-economic complex has its own water reservoir and a set of retaining structures and required culvert installations. In addition, the following environmental requirements are imposed on co-regulation of water runoff: - protection of waterfronts of the towns Meleuz, Salavat, Ishimbay and Sterlitamak from flooding in flood season; -protection of the territories of refineries in flood season (during water rise). Umaguzinskiy water power development has the following water sluices to control water stream: 1) submerged flood-discharge outlet; 2) shore flood spillway; 3) aggregates of powerhouse. General water carrying capacity of hydroelectric complex structures is 3915 м3/c. Nugushskiy hydroelectric complex consists of hydraulic engineering structure power room (1) and left shore spillway (2). Combined water carrying capacity of all hydroelectric complex structures here is 1250 м3/c. The authors investigated operation modes of Nugushskiy and Umaguzinskiy water power developments when linked into one water-economic complex and came to the conclusion that modes of operation of these water storage control structures should be adjusted in accordance with the operational condition of the main pressure installations and of downstream flood-control facilities. In particular, it is necessary to take into account the unfinished state of flood prevention measures in the middle reaches of the river Belaya.

Abstract Jinan is a city that typifies the water resource shortage in North China. This study selected nine indices to evaluate the regional water resources carrying capacity (WRCC), which is an important constraining factor in relation to socioeconomic development and the ecological environment. The AHP-CRITIC weighting method was applied to determine the index weighting, and WRCC dynamics during 2011–2016 were analysed and evaluated quantitatively using the fuzzy comprehensive evaluation method. The results revealed the following. (1) During 2011–2016, the comprehensive score of the WRCC was <0.4, indicating poor WRCC. (2) The degree membership of the average evaluation results to V1, V2, and V3 increased successively during 2011–2016. The degree membership of V2 in 2011–2013 was greater than that of V3; however, the situation was reversed during 2014–2016. (3) The indices of available amount of water resources per capita, utilization rate of water resources, water supply per capita, modulus of water supply, quota of domestic water demand, and population density were factors that affected the WRCC of Jinan unfavourably. Conversely, the indices of water demand per 10,000 Yuan industrial output value and water use rate of the ecological environment were factors that played positive roles in improving the WRCC.

Upper Cisokan sub-watershed is a natural ecosystem of water resource providers that can be used directly or indirectly by the community in it. The population rate and sectoral needs in a sub-watershed area are estimated have put pressure to the water resources balance. The value of the carrying capacity and the water criticality index in the existing condition and its projections for the next 10 years are known from the water balance analysis. The availability of water resources (Wn) was determined based on the flow rate probability (Q80) of Weibull Method, the value of groundwater estimation, springs and wells, and also the raw water supply of local water company. Water demand (qpt) was estimated based on Statistic data of Upper Cisokan sub-Watershed 2020 and the projection for 2030, industrial data, agricultural area data, livestock production data, and fishery area data. The water resources carrying capacity (Cw) of the Upper Cisokan sub-watershed is generally still adequate (High), but at the peak of the dry season, namely June to November, the water carrying capacity status shows a value of 1.84 (Critical) to 0.24 (Deficit). In general, the water criticality index is still safe (Not Critical), but in the dry period, especially in July, August and November, it shows a value of 125% to 421% (Very Critical). To anticipate the water crisis, all stakeholders should allocate water efficiently according to its availability. So that the sub-watershed ecosystem is sustainably provide ecosystem services for providing water resources to the community. Key words: Ecosystem Services, Water Supply, Water Demand, Water Balance, Water Resources Carrying Capacity, Water Criticality Index, Upper Cisokan Sub Watershed
