“…Meanwhile, socioeconomic development and population growth resulted in land use change, leading to additional pressures on the environment (Millennium Ecosystem Assessment, ). Human‐induced activities have significantly increased evapotranspiration because of large expansion of water‐intensive and irrigated agriculture (Kundu, Khare, & Mondal, ), changes in vegetation cover (Feng et al, ; Khazaei et al, ), and expansion of (plantation) forest (Tange, Shrestha, Shrestha, Datta, & Kawasaki, ; Yan, Zhang, Yan, Zhang, & Chen, ). Integrated land–climate changes resulted in a substantial change from basins' natural water supply–demand balance, particularly in the arid and semiarid regions.…”

Studying the interaction between hydrology, land use, and climate change is necessary to support sustainable water resources management. It is unknown how land management interventions in dry climate conditions can benefit water yield in the context of climate and land use change interactions. In this study, we assessed the effects of both land use and predicted climate change on the Mordagh Chay basin water yield using the Integrated Valuation of Ecosystem Services and Tradeoffs model. First, we modeled the current water yield, followed by developing six combined climate–land use scenarios until 2030 based on the CCSM4 climate model for the RCP4.5 and RCP8.5 scenarios. We used three future land use scenarios simulated by the Dyna‐CLUE model. The trend scenario of land use change, which does not include any improvements in irrigation efficiency, significantly affected basin water yield under both climate scenarios. Water yield decreases by 19.8% and 31.8% for the RCP4.5 and RCP8.5, respectively. Under all land use scenarios that included improvements in irrigation efficiency, the water yield responded positively. For the RCP4.5 scenario, the water yield was projected to increase between 16.6% and 18% depending on the land use scenario. The increase in water yield under the RCP8.5 climate scenario was much lower than for the RCP4.5 scenario (about one‐third). Overall, the results showed that by adopting appropriate irrigation efficiency, it is possible to achieve a better balance between environmental needs and regional economic and agricultural development. The results provide insight into possible sustainable development options and also provide guidance for managing the other Urmia Lake sub‐basins, whereas the approach of integrated assessment of climate, land use change, and land management options is also applicable in other conditions to help inform sustainable management.

“…Global and regional land surfaces rapidly undergo changes with increasing urbanisation, agricultural practices and ecological restoration projects (Li et al, 2017). Such land use changes influence the water balance of a region, affecting the available water supply and ET (Kundu et al, 2017). Changes in ET reflect the potential effects of different land use types on the climate, hydrological cycle and water resources of a region.…”

Effects of different land use types on potential evapotranspiration in the Beijing-Tianjin-Hebei region, North China

Potential evapotranspiration (ET 0) is vital for hydrologic cycle and water resource assessments as well as crop water requirement and irrigation demand assessments. The Beijing-Tianjin-Hebei region (Jing-Jin-Ji)-an important, large, regional, economic community in China has experienced tremendous land use and land cover changes because of urbanisation and ecological restoration, affecting the hydrologic cycle and water resources of this region. Therefore, we analysed ET 0 in this region using climate data from 22 meteorological stations for the period 1991-2015 to understand this effect. Our findings show that ET 0 increased significantly at a rate of 7.40 mm per decade for the region. Based on the major land use type surrounding them, the meteorological stations were classified as urban, farmland, and natural stations using the 2015 land use dataset. The natural stations in the northern mountainous area showed a significant increase in ET 0 , whereas most urban and farmland stations in the plain area showed a decrease in ET 0 , with only a few of the stations showing an increase. Based on the different ET 0 trends for different land use types, these stations can be ranked as follows: urban stations (trend value: −4.663 to −1.439) > natural stations (trend value: 2.58 to 3.373) > farmland stations (trend value: −2.927 to −0.248). Our results indicate that land use changes affect meteorological parameters, such as wind speed and sunshine duration, which then lead to changes in ET 0. We noted that wind speed was the dominant parameter affecting ET 0 at all the natural stations, and wind speed and sunshine duration were the dominant parameters affecting ET 0 at most of the urban stations. However, the main controlling parameters affecting ET 0 at the farmland stations varied. These results present a HAN Jingyan et al.: Effects of different land use types on potential evapotranspiration in Beijing-Tianjin-Hebei 923 scope for understanding land use impact on ET 0 , which can then be applied to studies on sustainable land use planning and water resource management.

“…Similarly, the water levels of lakes in Ethiopia have also shown changes following the impacts of human activities and climate variability. Three lakes found in the Ethiopian Rift Valley, i.e., Lake Beseka, Lake Awassa, and Lake Chamo, have shown an increase in volume while Lake Abiyata has climate variability on the hydrologic responses [27,[37][38][39][40][41][42][43]; however, only a few studies have been done to evaluate the combined impacts of the two changes [44,45].…”

Hydrological impacts of human activities and climate variability on Ketar and Meki watersheds of Lake Ziway basin, Ethiopia were studied using the soil and water assessment tool. Three land-use change and two climate variability scenarios were considered to analyze the separate and combined impacts on annual water balance, monthly streamflow, and spatial distributions of evapotranspiration and water yield. The evaluation showed that changes in land use resulted in an increase in annual surface runoff and water yield for Ketar watershed and an increase in annual ET for Meki. Similarly, the climate variability resulted in a decrease in annual ET, surface runoff, and water yield for Ketar watershed and a decrease in ET for Meki. Overall, climate variability has greater impacts on the monthly streamflow compared to land-use change impacts. Similarly, greater sensitivity in hydrologic response was observed for Ketar watershed compared to Meki watershed.
