“…Changes in climate elements, including an increase in air temperature, transform and accelerate both the water cycle and changes in the structure of water balance in river or lake catchments [30,[55][56][57]. The rapid decrease in the surface area of Rakutowskie Lake is probably a result of the observed increase in evaporation and periodically smaller precipitation ( Figure 6).…”

In this work we present the complicated situation of a faunistically and floristically valuable ecosystem of the Rakutowskie Lake wetlands complex, which is part of the Special Protection Area for Birds of “Błota Rakutowskie” (PLB40001) and “Błota Kłócieńskie” Habitats Directive Sites (PLH040031) included in the Natura 2000 network. Numerous ornithological observations have drawn our attention to the problem of rapidly progressing overgrowth of the lake and significant fluctuations in its water surface area. These fluctuations, especially in the spring period, significantly limit safe reproduction possibilities of very rare species of water–marsh birds. A multidirectional and comprehensive spectrum of research works allowed us to determine the genesis of the ecosystem and show that the shallow lake is undergoing the final stage in its evolution. The economic aspect of human activity (changes in land use and land development works) has contributed to serious degradation of the ecosystem. Climate changes observed in recent years (increased air temperature and, consequently, higher evaporation) additionally deepen and accelerate this process. The research made it possible to determine how the ecosystem functions today, but it is also an attempt to determine our predictions about its future.

“…As a result of the new institutional arrangements (fencing and grazing exclusion), stock rating decreased significantly after 2000, which had a significantly positive effect on vegetation conditions (Huang et al, 2009), but a negative effect on herders' livelihoods (increases in the cost of livestock production and decreases in the net income of herders; Uthes, Li, Zhen, & Cao, 2010). Li, Gao, Li, Yan, & Xu, 2017;Tao et al, 2015). Previous research showed that degraded grassland can recover under grazing ban conditions (Jiang, Han, & Wu, 2006).…”

Land‐use change and land degradation on the Mongolian Plateau from 1975 to 2015—A case study from Xilingol, China

et al. 2018

Land degradation is a severe environmental problem on a regional and global scale that is often aggravated by intensive land‐use and climate change. The arid to semi‐arid Xilingol in Inner Mongolia, China, is an example of an area that has witnessed continuous land degradation for decades, in spite of numerous attempts to reverse this trend. In this study, land‐use and land‐cover change (LUCC) between 1975 and 2015 was investigated for Xilingol based on multi‐temporal remote sensing images. The aim of the study was to derive detailed information on LUCC over space and time as a basis for assessing ecological and social consequences of land degradation in a bid to develop better strategies for combating land degradation. Two main LUCC processes and two distinct phases were identified: During Phase 1 (1975–2000), the LUCC pattern was dominated by land degradation, affecting 11.4% (22,937 km2) of the total area. During Phase 2 (2000–2015), land restoration increased (12.0% or 24,161 km2) whereas degradation continued, resulting in a further 9.5% (19,124 km2) of degraded land. The transition pattern changed accordingly. Our findings show that, in spite of notable restoration successes in the past, grassland degradation continues to be the main ecological and environmental problem in Xilingol, requiring the continued attention of decision‐makers. Strategic land‐use management has already had a significant influence on LUCC in this area, leading to the expectation that science‐based land‐use strategies can be developed to further reduce land degradation in Xilingol.

“…Data from remote sensing satellites, such as Landsat, MODIS, Sentinel-1, CBERS-1, and so on [9][10][11][12], has been widely used for mapping surface water. Landsat datasets are likely the most common data employed to identify the water surface because of their high spatial resolution, free availability, and their long sequence feature [10,13]. Han et al [11] used Landsat data to study changes in the winter wetlands of Poyang Lake from 1973 to 2013.…”

Lakes have an important role in human life and the ecological environment, but they are easily affected by human activity and climate change, especially around urban areas. Hence, it is critical to extract water with a high precision method and monitor long-term sequence dynamic changes in lakes. As the greatest natural lake of the Beijing-Tianjin-Hebei region, Baiyangdian Lake has a significant function in human life, socio-economic development, and regional ecological balance. This lake area has shown large changes due to human activity and climate change. The change monitoring process of the water surface is of great significance in providing support for the management and protection of the lake. The Spectrum Matching based on Discrete Particle Swarm Optimization (SMDPSO) method is a new, robust, and low-cost method for water extraction, that has obvious advantages in extracting complex water surfaces. In this paper, the SMDPSO method was used to extract the water surface of Baiyangdian Lake by Landsat images from 1984 to 2018. This method has a good effect on complex water surface extraction with vegetation, shadows, and so forth, and the Landsat images have higher resolution and longer time series. The main contents and results of this paper are as follows: (1) We verified the applicability of the SMDPSO method in the Baiyangdian Lake using visual interpretation and correlation analysis. The relative errors between observed and extracted results were all less than 5% in spring, summer, and fall, and the correlation coefficient between the water area and water level was 0.96. (2) According to seasonal verification and comparison of the extraction results, the SMDPSO method was used to extract the water surface area of Baiyangdian Lake during spring of the years 1984–2018. Water area changes of Baiyangdian Lake can be divided into four periods: Dry period (1984–1988), degraded period (1989–2000), stable period (2000–2008), and recovery period (2008–2018). The water area reached a maximum of 280 km2 in 1989 and a minimum of 44 km2 in 2002. (3) The possible causes of the changes in the water area of Baiyangdian Lake were also analyzed. The changes were caused by climate and human activities during the first and second periods, but mainly human activities during the third and fourth periods. In fact, effective policies combined with water conservancy projects were directly conducive to improving or even recovering the water and ecological environment of Baiyangdian Lake. Considering its importance for the benign development of the Beijing-Tianjin-Hebei Region and the construction of the Xiong’an New Area, a policy is necessary to ensure that the lake’s ecological environment will not be destroyed under the premise of economic development.
