“…The research results further affirm the conclusion that climate, socioeconomic development, and land use change collectively exacerbate the imbalance between water supply and demand. Even in water-rich regions like Guizhou, there is still a risk of localized water scarcity [20,44,54].…”

Land use change and water supply–demand assessment are critical to achieving regional sustainable development and improving human wellbeing. In the context of complex climate change and socioeconomic development, there is an urgent need for systematic assessment and forecasting studies on how to combine physical, geographical, and socioeconomic factors to clarify patterns of change in the land use change and water supply–demand, as well as to respond appropriately to different climate and socioeconomic development scenarios in the future. Based on the Shared Socioeconomic Pathways-Representative Concentration Pathway (SSP-RCP) scenarios, a framework for simulating future land use change and assessing water supply–demand in the coupled SD-PLUS-InVEST model was constructed. The land use change in Guizhou Province from 2020 to 2050 was simulated using the SD-PLUS model, and the water supply–demand conditions were projected for 2030, 2040, and 2050 under multiple scenarios (SSP126, SSP245, and SSP585). The research results indicated that (1) The land use change in the study area has significant spatial heterogeneity. It showed similar trends in the land use change in the SSP126 and SSP245 scenarios, with both artificial surfaces and forest showing an expansion trend, but the expansion of forest was most typical in the southwestern region in the SSP126 scenario, and there is a significant increase in the northeastern region in the SSP245 scenario. Additionally, there is a rapid expansion of artificial surfaces in the central region in the SSP585 scenario, and a more rapid expansion of cultivated land in the southeastern region, with a significant increase in the area of water bodies. (2) The changes in water supply from 2020 to 2050 under the three scenarios show a smaller increase (5.22–11.88%), a significant increase in water demand (29.45–58.84%), and an increase in the area of water shortage by about 2708.94–9084.40 km2, with the extent of the shortage increasing by about 23.71–79.50%. (3) According to the results of the SSP-RCP scenario projections, socioeconomic development has a significant impact on the growth of water demand, and climate and land use change may exacerbate the spatiotemporal heterogeneity of water supply–demand in the karst region. The systematic study of land use change and water supply–demand in Guizhou can provide a scientific basis for the sustainable management of regional ecosystems and the rational allocation of land and water resources.

“…River connectivity is essential for the conservation of freshwater ecosystems, because barriers alter both abiotic conditions and biotic communities, compromising biodiversity; however, the appreciation of this characteristic of rivers has been insufficiently considered in socio-environmental studies, which focus mainly on the acceptance of new dam construction [19][20][21]. Global climate change is having a major impact on water resources and the hydrological regime of rivers, prompting riparian communities to build reservoirs that attenuate flood waves and retain water for extended periods of time when droughts occur [22,23]. All these hydrotechnical constructions being built or under construction have become transverse and longitudinal barriers to natural aquatic ecosystems [24][25][26][27].…”

Anthropogenic pressure on water resources is affecting aquatic systems, requiring ecological analysis and restoration. This study proposes a new approach to assessing public perceptions of these activities. The methodology used is based on a structured questionnaire that looks at the general perception of the research topic, the economic readiness for community involvement and the identification of institutional mechanisms to implement river restoration measures. We used random sampling, guaranteeing results with a margin of error of 4.33%. The results show that the public and practitioners have different perspectives, and this can influence river restoration solutions, as they will contribute to a change in the way that longitudinally connected river restoration solutions are designed and implemented.
