“…As the tenth largest river basin in the world, the natural conditions of the Amur River Basin (ARB), a transboundary basin in eastern Eurasia, vary greatly from region to region. In addition, the impact intensity of human activities on the ground vegetation has varied considerably under the influence of different national policies, lifestyles, and economic development [34][35][36][37][38]. In recent decades, significant climate changes have been observed in the ARB, where an annual mean temperature warming rate of about 0.34 °C/10a for 1975-2004 was reported, which is approximately 2.5 times higher than that for the 1891-2004 period [39].…”

Information about the growth, productivity, and distribution of vegetation, which are highly relied on and sensitive to natural and anthropogenic factors, is essential for agricultural production management and eco-environmental sustainability in the Amur River Basin (ARB). In this paper, the spatial–temporal trends of vegetation dynamics were analyzed at the pixel scale in the ARB for the period of 1982–2013 using remotely sensed data of long-term leaf area index (LAI), fractional vegetation cover (FVC), and terrestrial gross primary productivity (GPP). The spatial autocorrelation characteristics of the vegetation indexes were further explored with global and local Moran’s I techniques. The spatial–temporal relationships between vegetation and climatic factors, land use/cover types and hydrological variables in the ARB were determined using a geographical and temporal weighted regression (GTWR) model based on the observed meteorological data, remotely sensed vegetation information, while the simulated hydrological variables were determined with the soil and water assessment tool (SWAT) model. The results suggest that the variation in area-average annual FVC was significant with an increase rate of 0.0004/year, and LAI, FVC, and GPP all exhibited strong spatial heterogeneity trends in the ARB. For LAI and FVC, the most significant changes in local spatial autocorrelation were recognized over the Sanjiang Plain, and the low–low agglomeration in the Sanjiang Plain decreased continuously. The GTWR model results indicate that natural and anthropogenic factors jointly took effect and interacted with each other to affect the vegetated regime of the region. The decrease in the impact of precipitation to vegetation growth over the Songnen Plain was determined as having started around 1991, which was most likely attributed to dramatic changes in water use styles induced by local land use changes, and corresponded to the negative correlation between pasture areas and vegetation indexes during the same period. The analysis results presented in this paper can provide vital information to decision-makers for use in managing vegetation resources.

“…The key to this study was identifying the different magnitudes and directions of the impacts of climate variability and land-use changes on the hydrological variables over the last several decades and further assessing the relationships between the individual climatic factors/land-use types and the hydrologic components. To identify the variations in the impacts, the authors divided the simulation periods according to the historical land-use changes reported in the literature mentioned in the study area section [17,18,24,27,29,49] and the characteristic analytical results of the climate and land-use changes.…”

“…As the 10th largest river basin in the world and the largest in the Russian Far East, the Amur River Basin (ARB) is one of the most vulnerable areas to climate change and human activities in the world [17]. In recent decades, the annual average maximum temperature, minimum temperature, mean temperature, and annual precipitation in the ARB have exhibited generally increasing trends [18][19][20][21]. Moreover, significant regional, seasonal, and interannual variations in temperature and precipitation have been investigated in portions of the ARB [1,7,[22][23][24][25].…”

“…Given the demands for water for agricultural and industrial development, a comprehensive understanding of the hydrological processes in the ARB under climate changes and anthropogenic activities in recent decades was necessary to provide decisionmakers with information about land-use planning and water management. Although the climatic variations and land-use changes in the ARB have followed general trends, such as global warming and farmland expansion, respectively, obvious differences have been observed in the changes in different regions and periods during recent decades [17,18,24,29]. The China portion of the ARB, which occupies the major agricultural lands of the study basin [46], has been particularly affected by human activities.…”

Under the joint effects resulted from different changes of climate and land-use regimes, spatial-temporal variations of hydrological processes took place in certain principles. Identifying the impact of changes in individual land-use types/climatic factors on hydrological processes is significant for water management and sustainability of watersheds. In this study, seven simulation scenarios were developed using the soil and water assessment tool (SWAT) model to distinguish the impacts of climate and land-use changes on the hydrological processes in the Amur River Basin (ARB) for four periods of 1980–1990, 1991–1999, 2000–2006, and 2007–2013, respectively. Based on the multi-period simulation scenario data, partial least squares regression and ridge regression analyses were performed to further evaluate the effects of changes in individual land-use types/climatic factors on hydrologic components. The results suggested that summer precipitation and summer average temperature were the dominant climatic factors, and crops and wetlands were the principal land-use types contributing to the hydrological responses. In addition, the drastic changes in crop and wetland areas and a clear decline in summer precipitation between the periods of 1991–1999 and 2000–2006 may account for the highest-intensity impacts of climate and land-use changes on the runoff at the outlet (−31.38% and 16.17%, respectively) during the four periods.

“…For example, many heat-related deaths occurred during the heat wave events in Chicago in 1995, in Western Europe in 2003, and in East Asia in 1994 [6][7][8]. Also, recent studies revealed significant worldwide warming and a general increase in the frequency and persistence of extreme temperature and precipitation events (e.g., [9][10][11][12][13]). So far, extensive researches have been conducted to detect the effects of climate change on climatic variables at a regional scale.…”

Istanbul, as one of the four anchor megacities of Europe, has shown a rise of 0.94 ∘ C in average annual temperature over the long period of 1912-2016 under impacts of anthropogenic climate change. A notable increase in temperatures has started after the 1940s, which is in parallel with the beginning of industrialization era in Istanbul. This warming is associated with an extensive population growth and accompanied the decrease in vegetation cover. Increasing in minimum series of temperature is more evident than maximum values and the rising rate of temperature values has been more pronounced during recent decades. The first significant upward trend in precipitation series has periodically started in 1920s, while there has been a stable trend from 2001 till today. The daily average of rainfall amount increased with a mean value of 58 mm during the total study period. Rising rate of daily maximum precipitation has been more evident in the last 3 decades, which is shown by the increased frequency of heavy rainfall. In this regard, both of the temperature and precipitation series had higher mean values (13.9 ∘ C and 878 mm) for the final period compared to the mean values (13.6 ∘ C and 799 mm) belonging to the first period .
