Impact of civil war on the land cover in Myanmar.

Environ Monit Assess

January 2025

College of Geoscience and Surveying Engineering, China University of Mining and Technology (Beijing), Beijing, China.

Exploring the response relationship between civil war, population and land cover change is of great practical significance for social stability in Myanmar. However, the ongoing civil war in Myanmar hinders direct understanding of the situation on the ground, which in turn limits detailed study of the intricate relationship between the dynamics of the civil war and its impact on population and land. Therefore, this paper explores the response relationship between civil war conflict and population and land cover change in Myanmar from 2010 to 2020 from the perspective of remote sensing using the land cover data we produced, the open spatial demographics data, and the armed conflict location and event data project.

Terrestrial ecosystems have vital impacts on soil carbon sequestration, but under disturbances from anthropogenic activities, the typical indicator combinations of SOC distribution in coastal areas remain unclear. On the basis of surface soil sampling and calculations of related eco-environmental indices in the Yellow River Delta (YRD), we performed geostatistical analysis combined with Spearman's correlation analysis, principal component analysis (PCA), and hierarchical clustering analysis (HCA) to explore the spatial heterogeneity of soil organic carbon (SOC) and influential spatiotemporal factors. Overall, the results revealed that in the seaward direction of the Yellow River, the SOC concentration decreased from west to east, with a low mean value of 5.

Understanding the establishment of ecological security patterns in arid and semi-arid regions is critical for global ecological risk prevention, control, and sustainable development. Nonetheless, there remains a relative deficiency in ecological risk assessment and construction of Ecological Security Patterns (ESP) in these areas, along with insufficient verification regarding the changes in ecological security patterns under diverse scenarios. This study employs Morphological Spatial Pattern Analysis (MSPA) to identify ecological sources and utilizes circuit theory alongside Minimum Cumulative Resistance (MCR) to delineate ecological corridors.

Coastal populations are susceptible to relative sea-level (RSL) rise and accurate local projections are necessary for coastal adaptation. Local RSL rise may deviate from global mean sea-level rise because of processes such as geoid change, glacial isostatic adjustment (GIA), and vertical land motion (VLM). Amongst all factors, the VLM is often inadequately estimated.

January 2025

Chongqing Key Laboratory of Land Quality Geological Survey, Southeast Sichuan Geological Group, Chongqing Bureau of Geology and Minerals Exploration, Chongqing 400038, China.

Heavy metals (HMs) pollution in agricultural soil-rice systems has attracted worldwide attention as it directly threatens regional ecological security and human health. To understand the heavy metal pollution of agriculture soil and rice in the high geological background areas, a total of 200 paddy soil and rice samples were collected in southeast Chongqing. The concentrations of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn) in paddy soil and rice were analyzed.

In the context of emphasizing on the food production, clean air guarding and sustainable development of agriculture, straw returning practices have been widely promoted, however, most studies have not linked straw returning adoption and smallholder's agricultural income in double-season rice cropping system. Based on a face-to-face survey data from 797 farmers in Jianghan Plain, Central China, we filled this gap by using the endogenous switching regression model to estimate the impact of farmer's straw returning on their agricultural income. The evidences show number of family laborers and technical training are the main factors influencing farmers' adoption of SR.

December 2024

Key Laboratory of Remote Sensing and Digital Earth, Aerospace Information Research Institute, Chinese Academy of Sciences, Beijing, 100101, China.

The global gridded crop production dataset at 10 km resolution from 2010 to 2020 (GGCP10) for maize, wheat, rice, and soybean was developed to address limitations of existing datasets characterized by coarse resolution and discontinuous time spans. GGCP10 was generated using a series of adaptively trained data-driven crop production spatial estimation models integrating multiple data sources, including statistical data, gridded production data, agroclimatic indicator data, agronomic indicator data, global land surface satellite products, and ground data. These models were trained based on agroecological zones to accurately estimate crop production in different agricultural regions.

Department of Geography, Urban Systems Institute, The University of Hong Kong, Hong Kong, 999077, China.

Urban building height, as a fundamental 3D urban structural feature, has far-reaching applications. However, creating readily available datasets of recent urban building heights with fine spatial resolutions and global coverage remains a challenging task. Here, we provide a 150-m global urban building heights dataset around 2020 by combining the spaceborne lidar (Global Ecosystem Dynamics Investigation, GEDI), multi-sourced data (Landsat-8, Sentinel-2, and Sentinel-1), and topographic data.

Article Synopsis
  • Desertification poses a significant challenge to sustainable development globally, but the Mu Us Sandy Land has successfully reversed it through effective national policies, showcasing positive ecological, economic, and social outcomes.
  • Long-term monitoring data is currently lacking, making it hard to fully understand the ongoing dynamics and factors driving these changes; thus, there's an urgent need for quantitative assessments of ecological restoration efforts.
  • Using Google Earth Engine and remote sensing data, this study produced a high-accuracy dataset showing a 69.45% decrease in desertification from 1986 to 2020 in the Mu Us Sandy Land, along with improvements in vegetation growth, demonstrating the effectiveness of restoration policies.

High-altitude areas are thought to be more sensitive to climate change, but long-term series of land surface temperature (LST) observations are still inadequate in low-latitude high-altitude mountainous areas. We investigated spatiotemporal variations in the LST and its dominant driving factors at different time scales based on the long-term series (2001 - 2020) of MODIS data over the Yunnan Province (YNP) in southwest China, with a special focus on elevation-dependent warming (EDW). The results indicated that annual LST generally increased at a rate of 0.

Tire and road wear particles (TRWPs) are an appreciable source of microplastics (MPs); however, knowledge of their large-scale occurrence and mass flux based on robust sampling and quantification is limited. Herein, the first city-wide survey of TRWPs across environmental compartments (road dust, snowbank, water, and sediment from rivers and lakes) along four ring roads (beltways) in Beijing was performed. TRWP concentrations ( = 74) were quantified using bonded-sulfur as a marker to reveal the city-wide spatial distributions and adopted to establish a framework estimating TRWP emission factors (EFs) and mass flux from generation to remote atmospheric, terrestrial, and aquatic transport.

Background: In 2019, the EAT-Lancet Commission proposed a global reference dietary pattern. Although research on the EAT-Lancet reference diet and its associations with mortality, cardiovascular disease, type 2 diabetes, dietary environmental impacts, and cost of diets is increasing, studies done in low-income and middle-income countries remain scarce. This study aimed to assess the health outcomes, environmental impacts, and dietary costs of adherence to the EAT-Lancet reference diet in China.
