Human activities are mainly responsible for the Aral Sea crisis, and excessive farmland expansion and unreasonable irrigation regimes are the main manifestations. The conflicting needs of agricultural water consumption and ecological water demand of the Aral Sea are increasingly prominent. However, the quantitative relationship among the water balance elements in the oasis located in the lower reaches of the Amu Darya River Basin and their impact on the retreat of the Aral Sea remain unclear. Therefore, this study focused on the water consumption of the Nukus irrigation area in the delta of the Amu Darya River and analyzed the water balance variations and their impacts on the Aral Sea. The surface energy balance algorithm for land (SEBAL) was employed to retrieve daily and seasonal evapotranspiration (ET) levels from 1992 to 2018, and a water balance equation was established based on the results of a remote sensing evapotranspiration inversion. The results indicated that the actual evapotranspiration (ETa) simulated by the SEBAL model matched the crop evapotranspiration (ETc) calculated by the Penman–Monteith method well, and the correlation coefficients between the two ETa sources were greater than 0.8. The total ETa levels in the growing seasons decreased from 1992 to 2005 and increased from 2005 to 2015, which is consistent with the changes in the cultivated land area and inflows from the Amu Darya River. In 2000, 2005 and 2010, the groundwater recharge volumes into the Aral Sea during the growing season were 6.74×109 m3, 1.56×109 m3 and 8.40×109 m3; respectively; in the dry year of 2012, regional ET exceeded the river inflow, and 2.36×109 m3 of groundwater was extracted to supplement the shortage of irrigation water. There is a significant two-year lag correlation between the groundwater level and the area of the southern Aral Sea. This study can provide useful information for water resources management in the Aral Sea region

Payment for Ecosystem Services (PES) is a commonly used policy tool to fund nature conservation efforts. However, the implementation of financial incentives may have unintended consequences on intrinsic motivations, such as attitudes and environmental values, resulting in reduced levels of pro-environmental behaviors after PES compared to those observed before PES. The effect of PES schemes on participants’ motivations is not well understood. To address this gap, we conducted a quantitative analysis of motivation effects in PES schemes using 155 data points from 126 primary studies. Our study found that: 1) 54% of PES projects had a crowding-in effect, reinforcing intrinsic motivations, while 42% had a crowding-out effect, weakening intrinsic motivations; 2) PES projects with community payments were more likely to induce crowding-out due to free-riding and reduced trust; 3) compliance monitoring was a weak predictor of crowding-in, possibly due to increased satisfaction; and 4) monetary payment, when compared to in-kind payment, was more likely to lead to crowding-out due to reduced autonomy. Our findings also suggest that crowding-in is associated with successful environmental outcomes, while crowding-out is associated with environmental failure. To enhance the effectiveness of PES programs, policymakers should promote motivation crowding-in and prevent crowding-out by using in-kind payments, addressing free-riding, and enhancing fairness and transparency through monitoring, where feasible.
