“…The carbon storage caused by check dams on the LP accounts for about 20% of the total forest carbon storage in China (Wang et al, 2011;Zhao & Zhou, 2006). With the combined effect of more than 260,000 km 2 terraces, the NPP of the LP has continued to grow since 2000 (Chen et al, 2022;Feng et al, 2013Feng et al, , 2016. Apparently, SWCP has a significant effect on carbon storage in the LP (Ran et al, 2018).…”

“…Grain‐for‐Green Program (GFG), the largest SWCP, implemented since 1999, has contributed to 25% of global greening (Chen et al, 2019). In addition, check dams and terraces that have been constructed as early as the 1970s, are widely distributed in the ecologically fragile Loess Plateau (LP) in China (Abbasi et al, 2019; Chen et al, 2022; Wang et al, 2011). There have been more than 110,000 check dams located in the LP, which have stored more than 2.1 × 10 10 m 3 sediments in recent decades (Wang et al, 2011).…”

Vegetation carbon sequestration, usually expressed by net primary production (NPP), is an important ecosystem service (ES) to mitigate global warming. Multiple soil and water conservation projects (SWCPs) have been implemented to restore disturbed ecosystems on the Loess Plateau (LP), as one of the most eroded areas in the world.However, responses of NPP to the conservation projects are unclear due to trade-offs between NPP and other ESs. Herein, we quantified NPP and other key ESs (i.e., water yield, soil conservation, and crop production) and the spatio-temporal trade-offs among them, using RS/GIS techniques and ecosystem modelling in the Yanhe basin of the LP from 1990 to 2020. Furthermore, the structural equation model was used to quantify the impact of ecological restoration projects and programmes such as check dams, terraces, and the Grain-for-Green (GFG) on NPP. As shown by our results, NPP reached 457 t ha À1 in 2020, which was twice what it was in 1990. Moreover, we found increasing trade-offs between NPP and other ESs at sub-basin scale. Specifically, 63% of NPP changes were explained by ESs and SWCPs. The combined action of check dams and GFG can promote NPP and balance trade-offs between NPP and other ESs, while terracing decreases NPP indirectly according to its specific soil and climate conditions. Overall, the main findings provide a better understanding of the interacting processes of multi-projects that influence vegetation carbon sequestration and the sustainable utilization of ESs in hill and gully regions of the LP.

“…The study showed a significant decreasing trend in vegetation cover, but surface runoff increased in the late baseline period. Chen et al (2022) developed a streamflow production model for the Chenggou River watershed, confirming that terraces and check‐dams construction did reduce runoff. On the one hand, terraces and check‐dams possess a favourable function of storing water resources (Liu et al, 2023), and the stored water resources are primarily consumed for crop growth (Bruins et al, 2019).…”

Runoff response to multiple land‐use changes and climate perturbations is distinct, and the main influencing factors vary significantly in different regions. However, few have simultaneously considered the effects of multiple land use changes (vegetation cover changes, terraces and check‐dams construction, and urban expansion) and climatic perturbations (precipitation, potential evapotranspiration, and temperature) on runoff and constructed separate expressions for distinct study areas. This article attempted to determine the main influencing factors of runoff according to the fitting function in the eight subregions of the middle Yellow River (MYR), construct the expressions between the controlling parameter in the Budyko framework and the main factors, and quantify the contribution of climate factors and land use changes to runoff by combining the elasticity coefficient in each subregion. The results indicated that climate factors and land use changes could significantly impact controlling parameters, and there were differences between regions. Climate change promoted an increase in runoff, while land use change promoted its reduction, and the reduction value outweighed its increase. In terms of land use changes, increasing vegetation coverage could suppress runoff reduction, while constructing terraces and check‐dams could promote its reduction. The urban expansion benefited runoff collection and, therefore, could suppress runoff reduction. Its absolute contribution rate exceeded 200% in apparent urban expansion areas. In addition, the contribution rates of land use to runoff changes in the northern arid and semi‐arid regions were significantly higher than those in the southern, and they were more sensitive to land use changes. The research results can provide a reference for analysing the runoff response to different land‐use changes and can further advance people's understanding of the water cycle.

“…For the stations under the impact of the dam, the significantly decreasing trend was almost twice as high as the share of stations showing a significantly increasing trend [38]. In the case of the catchment of the Chenggou River, it was determined that the dam system can retain more than 50% of the flow capacity of the catchment [39]. The Xiaolangdi Dam is responsible for approximately 52% of outflow reduction both in a year and outside of the flood season and for approximately 32% of flow increase during the flood season [40].…”

Water resources are of elementary economic and environmental importance, and the observed global transformations as well as regional environmental conditions necessitate activities aimed at providing an optimal amount of water at different levels. One such solution is hydrotechnical infrastructure that permits the precise control of the amount of water in the catchment. This paper presents results concerning changes in the water flow in the Główna River in Poland before (1955–1983) and after (1984–2021) the construction of the Kowalski Reservoir. In the former period, there were no changes in water flow, and the obtained results were not statistically significant (p 0.05). In the period after the construction of the reservoir, a decreasing trend in monthly flow was observed in December, April, July, September, and October. Moreover, a decrease in 1, 3, 7, and 90 day maximum flow was observed. For maximum 30 day flow, the changes were below the threshold of the adopted significance level. Moreover, minimum flow in the period after the construction of the reservoir showed no significant decreasing trend. In hydrological terms, the reservoir served its purpose by contributing to the stabilisation of the water flow. This information is important from the point of view of an increase in retention and corresponds with a broader programme conducted in the territory of Poland. In the context of the construction of further reservoirs, it is important to investigate the current range of changes in water circulation for objects of the type already functioning in the environment, constituting an actual point of reference.
