“…Moreover, a positive effect of climate variability on runoff can be found when the annual precipitation is high. This phenomenon was also found in some earlier studies in other areas of China, for example, the Haihe River Basin [12] and the Weihe River Basin [30]. Precipitation is the main source of runoff in the URRB, and the relationship between P and R is closely related.…”

Quantifying the effects of climate variability and human activities on runoff changes will contribute to regional water resource planning and management. This study aims to separate the effects of climate variability and human activities on runoff changes in the upper catchment of the Red River Basin in China. The Mann-Kendall test and Pettitt's test methods were applied to identify the trends and change points of the hydro-meteorological variables. The hydrological sensitivity, climate elasticity and hydrological simulation methods were adopted to estimate the contributions of climate variability and human activities to runoff changes. Results showed that annual runoff significantly decreased by 1.57 mm/year during the period of 1961-2012. A change point in annual runoff coefficient occurred in 2002. Accordingly, the annual runoff series were divided into the baseline period and the impacted period (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012). Mean annual runoff of the impacted period decreased by 29.13% compared with the baseline period. Similar estimates of the contributions of climate variability and human activities were obtained by the three different methods. Climate variability was estimated to be responsible for 69%-71% of the reduction in annual runoff, and human activities accounted for 29%-31%. Climate variability was the main driving factor for runoff decrease in the catchment.

“…Wang et al [16] proposed identifying the individual impact of human activity and climate change on changes in runoff of the Sanchuan River by applying a well-developed hydrological model to naturalize runoff over the period of human disruption, with the difference between naturalized runoff and recorded runoff being induced by human activity. The method was called the simulation-based approach and was applied to other catchments by hydrologists [17,[30][31][32]. For example, Ma et al [31] found climate change has led to a stream flow increase of 40.8 m 3 /s per year for the Huai River basin, while human activity has resulted in a stream flow decrease of 33.51 m 3 /s per year.…”

Abstract:Stream flow plays a crucial role in the environment, society, and the economy, and identifying the causes of changes in runoff is important to understanding the impact of climate change and human activity. This study examines the variation trends in recorded runoff for the Xinshui River, a tributary of the Yellow River on the Loess Plateau, and uses hydrological simulations to investigate how climate change and human activity have contributed to those trends. Results show that the recorded runoff at the Daning station on the Xinshui River declined significantly from 1955-2008 with an abrupt change occurring in 1973. The Simplified Water Balance Model (SWBM) simulates monthly discharge well with a Nash-Sutcliffe efficiency (NSE) coefficient of 78% and a relative error of volumetric fit (RE) of 0.32%. Runoff depth over the catchment in 1973-2008 fell by 25.5 mm relative to the previous period, with human activity and climate change contributing 60.6% and 39.4% of the total runoff reduction, respectively. However, the impacts induced by climate change and human activities are both tending to increase. Therefore, efforts to improve the ecology of the Loess Plateau should give sufficient attention to the impacts of climate change and human activity.

“…This indicates that poverty is no longer an issue in northwest China. These results are not surprising because significant infrastructure construction [22,23] and poverty reduction [24,25] have been achieved in the last 40 years, but at the expense of health risks [26] and environmental degradation [17,21]. …”

“…With rapid economic development in the in recent years, many problems have arisen. These include an increasing scarcity of water resources [17], climate change [18], water pollution and regional ecological environment deterioration. A stratified random sampling strategy was used to include all the major drainage areas and direct beneficiaries of the basin as described in Table 1 below.…”

Almost half of the total area coverage of the basin (135,000 km 2 ) lies in Shaanxi Province (Figure 1).…”

This paper analyzes public awareness and perception about current issues of environmental and water resources in China in comparison to the socio-economic issues. The ranking, Likert scale, and ordered logit analysis were applied to data from 1773 sample residents in northwest China. The results show that the residents rank the degradation of the ecological environment and water resources as the most important issue, and education, political involvement, gender, employment, and residential location play significant roles in explaining the observed differences in concern. Of the possible environmental and water resource restoration policies, residents ranked water quantity and quality, agricultural and industrial water use, erosion control, vegetation restoration, wildlife habitat, animal brooding and migration services, biodiversity landscape, and eco-tourism from one to nine in order of importance, respectively. The results are relevant for policymaking and imply that environmental restoration is a high public demand. Welfare gains from investments in it would be higher or equal to gains from other socio-economic and livelihood activities. Thus, public policies must emphasize restoring and maintaining a sustainable ecological environment.
