“…Ecological source refers to lands with important ecological service function and relatively high ecological sensitivity. They are normally aggregated in spatial distribution, usually consisting of relatively large natural ecological patches, playing a significant role in maintaining the ecological stability of that area [21,31,32]. The selected ecological source was based on the assessment of comprehensive ecosystem services, choosing two levels of relatively high comprehensive ecosystem services (the extremely and highly important) to be the ecological source of the research area.…”

“…They designed, combined and distributed various natural and human factors in the region, generating plans of spatial configuration consisting of points, lines, and planes, with the characteristics of multiple purposes, levels, and types. They hoped to maintain the functional and structural integrality of the ecosystem and seek the balance between socioeconomic demand and ecological security at the macro-level [21]. More than 20 years of development gradually formed the basic paradigm of EPS construction, with the characteristics of "source recognition, resistance surface construction, corridor selection, security pattern identification" [22].…”

The construction of an ecological security pattern (ESP) is one of the basic methods to protect regional ecological security and enhance people’s well-being. In the case of Anhui province, located in the Yangtze River Delta region of China, regional ecological sources were assessed and recognized in terms of ecosystem services, and regional ESP was then constructed based on circuit theory. Current density was applied to analyze the significance of patches and corridors and recognize sticking points, and thereby strategies were introduced to optimize regional ESP. Results of ecosystem services function assessment showed that there were 47 ecological patches, 107 ecological corridors, 16 pinch points, and six sticking points in the ESP of Anhui province. The watershed of the Yangtze and Huai rivers divides the ESP of the northern and southern Anhui, which has huge landscape spatial heterogeneity. Areas with relatively good ecological resources were basically located between Dabie Mountain area in the west and the low hilly area in the south of Anhui, with mostly woodland and farmland as ecological sources. However, cities in the northern Anhui, also in the north of the watershed of the Yangtze and Huai rivers, face severe situations in terms of environmental protection. This study conducted spatial analyses on ESP with different thresholds and proposed to classify different ESPs according to ecological control. This helps to alleviate the contradiction between economic development and environmental protection, and improve the supply capacity of regional ecosystem services, in order to satisfy the regional demand for ecosystem services. Meanwhile, this study offers more methods to construct regional ESP and introduces targeted measures to improve connectivity, which is of practical guidance for the connectivity and optimization of ecological patterns.

“…Hence, it is necessary to carry out scientific studies to assess land cover changes and land use to determine human disturbance impacts in the Earth system (Abbasi et al, 2015; Beyene, 2015; Caúla et al, 2017; Prasad & Ramesh, 2018). Regional variation in dominant vegetation and other landscape shows climate change impacts ecosystems with time and space (Jacob et al, 2016; Peng & Zhou, 2018). Thus, changing vegetation response due to climate is relevant to understanding Earth's surface processes, such as the changes in runoff discharge, forest fires, or biota (Keesstra, 2007; Pereira et al, 2016; Russell & Ward, 2016).…”

Field‐based investigations of land use/cover changes are time‐consuming and challenging for large areas, where short‐ and long‐term changes in climatic and hydrologic variables affect ecosystem services. Thus, there is a substantial demand to boost the new modelling framework and employ remote sensing capabilities to quantify hydro‐climatic impacts on land dynamics. In this study, a conceptual framework has used to assess the climatic land greening, climatic land degradation, nonclimatic (hydrological) land greening, and nonclimatic (anthropogenic) land degradation responses with hydro‐climatic variables under dry and wet spells' effect in the Betwa River basin (BRB) of central India. Remotely sensed moderate‐resolution imaging spectro‐radiometer (MODIS) (normalized difference vegetation index [NDVI] and land cover) time‐series datasets had been used to quantify spatiotemporal changes in major land use/cover classes. The standardized coefficients for rainfall (β = 0.62) and relative humidity (β = 0.32) showed their high relative importance in the relationship analysis performed using multiple linear regression (MLR). The result indicates that dominant agricultural cropland has been significantly impacted by changes in maximum and diurnal temperature, which affirm degradation, and positively responded by changes in rainfall, minimum temperature, and aridity index, which demonstrate greening wet period. Spatial analysis showed that land degradation affecting ecosystem services had been variedly distributed from the upper to lower basin due to more climatic impacts than anthropogenic disturbances. Thus, the developed conceptual framework can be adopted to discover dynamic land consequences and understand their responses for sustaining ecosystem services in the dominant agricultural region.

“…Three papers in this Special Issue of Natural Resources Research focus on this matter. Prasad and Ramesh (2019), Peng and Zhou (2019), and Statuto et al (2019a) proposed three different GIS models for the analysis of the spatiotemporal evolution of LULC changes in an ecologically fragile area in the Alappuzha District (India), in a rural landscape in Mianzhu (China), and in a rural landscape in Basilicata region (Italy), respectively. The results are very different, highlighting the importance of the development and application of local-scale models.…”

“…The results are very different, highlighting the importance of the development and application of local-scale models. While in rural areas with lower population growth the landscape has naturally evolved without any human intervention (Statuto et al 2019a), the population growth in India and China is leading to an increase in built-up land area with reduction in cultivated agricultural land (Prasad and Ramesh 2019;Peng and Zhou 2019). The authors highlighted the importance of these models for land planning to analyze land-use change dynamics in order to avoid future conflicts among alternative land uses.…”
