Effects Of Climate Change And Human Activities On Aeolian

Di: Ava

In this study, we aimed to examine the changing trends of annual landscape patterns along the Chinese coastal zones from 1992 to 2018. By means of quantile regression and grid-by-grid random forest regression, we then quantified the heterogeneous effects of responsible climate change and human activities on landscape patterns at the Human activity primarily affects aeolian processes by directly or indirectly changing the erodibility of sediments that are suitable for wind transport or by altering aeolian sediment budgets.

Climate change and the ocean • MBARI

The dual effects of climate change and human activities were examined by correlation analyses of data from 87 meteorological stations and economic statistical data of the QTP. Results show that: (a) The vegetation in central and southwestern QTP with high altitudes was improving due to the warm-humid climate trend. However, the relative contribution of natural vs. human-induced disturbances has not been quantified, making it difficult to separate what is expected from climate variability and/or climate change from direct human impacts. Aeolian desertified land rapidly expanded from 1975 to 1990 under the combined effects of climate changes and unreasonable human activities. After the 1990s, the main driving factors responsible for the decrease in desertification were positive human activities, such as the series of antidesertification and ecological restoration

Effects of Climate Change and Human Activities on Aeolian Desertification Reversal in Mu Us Sandy Land, China Article Full-text available Jan 2022 Notably, the significant increase in regional flaming fire activity since ~1.00 ka can be primarily linked to human-set fires with the usage of gunpowder in frequent wars. This research holds great importance in enhancing our understanding of the long-term interactions among fire activities, climate change and human activities.

AEOLIAN PROCESSES AND THE BIOSPHERE

The combined effects of climate change, topography and human interference on desert vegetation should be considered in future restoration practices. China is a country largely affected by desertification. The main purpose of this article is to analyze interannual and seasonal changes in fractional vegetation cover (FVC) in the Mu Us Sandy Land (MUSL). It uses fused remote sensing data to quantitatively analyze the response of FVC to climate change and human activities. We systematically review and integrate the geological archives and instrumental data to trace the variations of aeolian activity on sub-orbital, centennial, and decadal timescales in CA, and assessed the relationship between aeolian activity changes and climate changes, atmospheric circulation system changes and human activities.

Aeolian processes affect the biosphere in a wide variety of contexts, including landform evolution, biogeochemical cycles, regional climate, human health, and desertification. Collectively, research Accurately identifying the contributions of climate change and human activities to desertification will support effective strategies for combating desertification. In this study, we employed the changes in net primary productivity (NPP) in areas of aeolian desertification on the Qinghai-Tibet Plateau from 2000 to 2014 to determine the dynamics of desertification.

Climate variability and human activities were driving forces controlling vegetation cover changes, and their effects on vegetation dynamics varied by region. The response of vegetation dynamics was stronger for precipitation than temperature, indicating that precipitation was the main climate variable influencing the NDVI changes.

Human activities on the earth’s surfaces create changes and hence the studies of the effects of humankind fall within the realm of geomorphology. The applications of geomorphology surveys in various aspects of the land for numerous specific needs of

Effects of Climate Change and Human Activities on Aeolian Desertification Reversal in Mu Us Sandy Land, China Article Full-text available Jan 2022 ABSTRACT Aeolian desertification is the dominant desertification type in northern China. The robust relations between climate variables and desertification indicators must be established while Previous studies attempting to quantify the contributions of climate change and human activities to runoff variations in a changing environment have widely focused on an annual scale, while seasonal scales are rarely involved. China is the largest socialist country in the world, and its economic development is affected by its Five-year Plan policy. To this end, the upper

The dynamic changes in these services are primarily influenced by human activities and natural climate changes. However, existing studies lack a quantitative evaluation of the contributions of climate change and human activities to the spatiotemporal changes in wind erosion control services on the Loess Plateau. ABSTRACT The nonparametric Mann-Kendall test and the Pettitt test were employed to examine the change trends and shifts of runoff and Abstract The aeolian desertification in Mu Us Sandy Land (MUSL) in northern China have been paid much attention, but the relative contributions of climate change and human activities to desertification dynamics are still not clear.

Aeolian processes affect the biosphere in a wide variety of contexts, including landform evolution, biogeochemical cycles, regional Here the temporal trends in potential evapotranspiration (PE) and precipitation were selected as climate change indicators, five possible scenarios were established and relationships between desertification and the climate change indicators were examined for different time periods across northern China.

It provides free access to secondary information on researchers, articles, patents, etc., in science and

In addition to human activities and anthropogenic pressures, climate change could also drive desertification in the long term. Unfortunately, we still lack synthetic assessment and comparison analysis on how climate change affects the desertification dynamics in China’s drylands in the context of ‘warming-wetting’ trend in these Over the past 40 years, the climate has been changing and human disturbance has increased in the vast Qinghai-Tibet Plateau (QTP). These 2 factors are expected to affect the distribution of a large number of endemic vertebrate species. However,

Qinghai Lake is the largest saline lake in China. The change in the lake volume is an indicator of the variation in water resources and their response to climate change on the Qinghai-Tibetan Plateau (QTP) in China. The present study quantitatively evaluated the effects of climate change and land use/cover change (LUCC) on the lake volume of the Qinghai Lake in Aeolian sediments are widely distributed in the eastern Qaidam Basin (QB), the main habitats for human in the hyper-arid basin during the Holocene, especially since 3 ka. The evolution of aeolian sediments is an important factor for the environmental change, and influence human activities and migration.

In this Review, de Souza and Weaver discuss the potential effects on vector-borne diseases of climate change, weather and other anthropogenic factors, including land use, human mobility and

In 2% of the whole area, the declining trend of ecosystem service value caused by climate change was weaker than the increasing trend of ecosystem service value caused by human activities. Thus, the ecosystem service value of 26% of the studied area was jointly reduced by climate change and human activities. Climate change and human activities altered the diversity and composition of soil microbial community in alpine grasslands of the Qinghai-Tibetan Plateau.
