Grain for Green project (GGP) initialed by China government since 1999 has achieved substantial achievements accompanied with surface runoff decrease in the Loess Plateau but impacts of large-scale afforestation on regional water resources are uncertain. Hence, the objective of this study is to explore the impact of land use change on generalized water resources and ecological water stress using blue and green water concept taking Yanhe River Basin as a case study. Soil and Water Assessment Tool (SWAT) is applied to quantify summary of green and blue water which is defined as generalized water resources, ecological water requirement of vegetation (forest and grass), agricultural water footprint and virtual water flow are considered as regional water requirements. Land use types of 1980 (scenario?), 2017 (scenario?) are input in SWAT model while keeps other parameters constant in order to isolate the influence of land use changes. Results show that average annual difference of blue, green and generalized water resources is -72.08 million m 3 , 24.34 million m 3 , -47.74 million m 3  respectively when simulation results of scenario? subtracts scenario?and it presents that land use change caused by GGP leads to decrease in blue and generalized water resources whereas increase in green water resources. SURQ in scenario?is more than that in scenario?in all the study period from 1980-2017, green water storage in scenario?is more than that in scenario? in all the study period except in 1998; whereas LATQ in scenario?is less than that in scenario? except in 2000 and 2015, GWQ in 1992, 2000 and 2015, green water flow in 1998. Blue water, green water storage and green water flow in scenario? is less than that in scenario?in the whole basin, 12.89 percent of the basin and 99.21 percent of the basin respectively. Total WF increases from 1995 to 2010 because forest WF increases significantly in this period though agricultural WF and grass WF decreases. Ecological water stress index has no obvious temporal change trend in both land use scenarios but ecological water stress index in scenario? is more than that in scenario?which illustrates that GGP leads to increase of ecological water stress from perspective of generalized water resources

This review article aims to increase our understanding in the strengths, weaknesses, opportunities and threats of implementing the basin approach for water resources management in Ukraine. To this end, this article implements that SWOT analysis for discussing the transition from the administrative approach towards the basin approach. The SWOT analysis consists of the four main aspects: Strengths, Weaknesses, Opportunities and Threats. Strengths and Weakness include strong and weak points of implementing the basin approach, respectively. Opportunities are windows for implementing actions to facilitate the basin approach and increase the effectiveness of this approach. Threats include risks for implementing the basin approach. In order to better understand opportunities, the main drivers and causes of water pollution are also discussed in the article. Results of the review show that climate change affects the availability of water resources strongly. Human activities namely the poultry production are important polluters of water resources. The article summarizes the correct water resources management approaches and proposes four main strategies for implementing the basin approach within the SWOT analysis. The first strategy deals with the successful transition from the administrative management towards the basin management of water resources. The second strategy deals with an increase in the access of the public to the water resources information including water quality. The third strategy deals with integrating the European Union water-related directives in the national environmental policies. The fourth strategy deals with reducing pollution levels in water systems through improved technologies. Next steps are to develop an integrated approach to account for strengths, weaknesses, opportunities and threats of the four strategies. It is important to develop water indicators to facilitate an integrated assessment of water resources for different water uses while accounting for water quality. Future research can focus on future scenarios to project water quality under global change and to assess effects of the national policies on reducing future water pollution from urbanization and agricultural sectors.

The paper discusses the system of water resources management and analyzes the effectiveness of its particular elements functioning. The authors have found the following factors of the water sector development: implementation of the strategic documents and attainment of the preset objectives, increasing of investments to the water sector and the self-funding level of the water sector enterprises, provision of scientific/information support for the management system. Application of the SWOT-analysis method have assessed the strong and weak aspects of the water resources management system, as internal conditions of its establishment. The external factors comprise possibilities of the system development, both positive aspects and dangers. Both national components of the system of state governing as a whole and factors affecting the situation at the international level were acknowledged as external factors. The conducted analysis enabled to conclude about necessity of improvement of the water resources management system of the Russian Federation in order to raise effectiveness of its functioning.

<p>Water stress has increased in many regions of the world during the past decades. It would be likely to continue in the near future due to intensified human activities and changing climate. Better projection of future water stress will facilitate water resources management and planning. Based on the improved water stress index (), we assess the future changes in water stress at the country level under climatic change and socioeconomic dynamics (e.g., population growth, economic development, land-use change) across scenarios. The water deficit, the unmet water demands against local water resources, is estimated for each country. The spatiotemporal characteristics of the global water stress are demonstrated and the main driving force is identified for the exacerbated stress on humans. The monetary value of the water deficit is estimated based on the water price valued for different sources of water withdrawal (e.g., surface water, groundwater, desalination, etc.). The total costs to mitigate or eliminate future water stress are estimated for each country. Finally, the risks and vulnerability due to global change in the future are assessed for each country. This study could be a reference for adaptation to climate change and the potential costs to achieve the SDGs in 2030.</p>

SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis is a useful tool for sustainable development and decision making about environmental planning and water resources management. This analysis was applied in order to evaluate the water resources of the wider area of Sperchios River. Sperchios River basin, with an average altitude of approximately 810m, covers an area of 2116 km2. The river is recharged by many streams of permanent and periodic flow and discharges in Maliakos Gulf. The steep slopes, which are present within approximately 2/3 of the total length of the river course, form a rather mountainous topography (streamy, with crucial flooding peaks and very intense sediment yield). Only in the last downstream part of Sperchios course, the topography gradually changes into a lowland relief, with an extent at the river mouth of 1830 km2. At this part of Sperchios severe cases of flooding have been occasionally observed and reported. Regarding the SWOT applications on the wider area of Sperchios River, various data were processed (geological, meteorological, hydrological, hydrogeological, land use, socio-economic and environmental parameters) in order to suggest a water management planning in the area.
