Special issue : Advanced remote sensing methods for monitoring and analyzing impacts of natural disasters on land cover and land use
This Special Issue is devoted to the cutting-edge field of advanced remote sensing methods applied to monitor and analyze the intricate impacts of natural disasters on land cover and land use processes. In an era marked by an increasing severity of disasters, such as hurricanes, floods, wildfires, extreme droughts, and landslides, leveraging technological advancements becomes paramount in understanding, assessing, and responding to the dynamic changes in terrestrial ecosystems. The published papers would promote innovative remote sensing techniques, including satellite passive optical and infrared imagery, including hyperspectral, as well as active remote sensing by lidars and radars. These methods offer a comprehensive view of the immediate and long-term effects of natural disasters, using the visible spectrum and beyond to assess alterations in vegetation health, soil composition, built infrastructure and topographical features. The research papers will not only investigate the physical transformations of land cover caused by natural disasters but also delve into the secondary consequences, such as habitat loss, altered hydrological patterns, and changes in land-use practices. The published studies would demonstrate the integration of machine learning algorithms and artificial intelligence in processing Big Data, enabling more efficient and accurate detection of post-disaster changes. This would showcase how advanced remote sensing methods empower us to monitor, analyze, and provide information for decision-makers to respond to the complex impacts of natural disasters on land cover and land use. The ultimate goal of this research is to enhance our ability to monitor recovery processes and inform resilient land-use planning. The research outcome would provide decision-makers concise information to enable timely response to the complex impacts of natural disasters on land cover and land use and contribute to sustainable ecosystem management in disaster-prone regions.

Natural lands around the world are being converted and degraded at unprecedented levels. Three-quarters of land has been significantly impacted by humans through pollution, urban expansion, conversion to crop or livestock production, intensive logging in natural forests and other activities. These changes contribute to climate change, threatening biodiversity and disproportionately impacting vulnerable communities. In fact, the rate of species extinctions is also accelerating, with some experts warning that a sixth mass extinction is under way. To mitigate emissions from land cover changes, build resilience for supply chains and working lands, and protect habitats and the communities and wildlife that depend on them, it is more important than ever to limit human conversion of natural lands. Commodities sourced from land are a major driver of this conversion, but now a new tool can help companies that source these commodities change the way they operate: Land & Carbon Lab has collaborated with World Wildlife Fund and Systemiq to lead the development of an open source Natural Lands Map. This map uses the best available global and local geospatial data that establishes a common baseline companies can use to visualize the extent of natural land in 2020, and through target setting, to assess whether they may be responsible for conversion after 2020. The Natural Lands Map can also help companies make decisions around acquisitions and the impacts on natural land from future business activities. Find More

| | As anthropogenic climate change-fueled extremes increasingly impact people worldwide, including extreme humid heat and drought conditions, there is a growing need for high spatio-temporal resolution data on both current and projected hydrometeorological and temperature variables and extremes. The Climate Hazards Center (CHC) Coupled Model Intercomparison Project Phase 6 (CHC-CMIP6) was created in answer to this need: this dataset has been explicitly developed to support the analysis of climate-related hazards over the recent past and in the near-future. This climate projection dataset contains global, daily gridded data for the observational (1983-2016) and projection (2030 and 2050) periods to be used in the identification and monitoring of hydroclimatic extremes. The dataset contains global daily high resolution (0.05°) grids of the Climate Hazards InfraRed Temperature with Stations (CHIRTS-daily) temperature product, the Climate Hazards InfraRed Precipitation with Stations (CHIRPS) precipitation product, and ERA5-derived relative humidity, from which which Vapor Pressure Deficits (VPD) and maximum Wet Bulb Globe Temperatures (WBGTmax) were derived.

| | The population of Africa is expected to rise to 2.5 billion by 2050, with more than 80% of this increase concentrated in cities. Africa’s anticipated population growth has serious implications for urban resource utilization and management, necessitating multi-level monitoring efforts that can inform planning and decision-making. Commonly, broad extent (e.g., country level) urban change analyses only examine a homogenous “developed” or “built-up” area, which may not capture patterns influenced by the heterogeneity of landscape features within urban areas. Contrarily, studies examining landscape heterogeneity at a finer resolution are typically limited in spatial extent (e.g., single city level). The goal of this study was to develop and test a hierarchical integrated mapping framework using globally available Earth Observation data (e.g., Landsat, Sentinel-2, Sentinel-1, and nightlight imagery) and accessible methodologies to produce national-level land use (LU) and urban-level land cover (LC) map products which may support a range of global and local monitoring and planning initiatives.

Remittances and Livestock Management in Agropastoral Households in Rural Kyrgyzstan: Telecoupled Impacts of Globalization
Christian Kelly Scott, Elizabeth A. Mack, Guangqing Chi, Kamilya Kelgenbaeva, Geoffrey M. Henebry
Rural Sociology, Vol 89, Issue 2, https://doi.org/10.1111/ruso.12552

Agropastoralism and international labor migration are livelihood strategies that are interconnected as dominant ways of life across rural Kyrgyzstan. A prevalent rural livelihood strategy—agropastoralism—is closely tied to agrarian semi-nomadic ways of life that link families and communities to the surrounding mountain environment. Another livelihood strategy—international labor migration—links or telecouples communities and income streams to transnational family structures, international labor markets, and distant economies. This article examines four hypothetical relationships between key elements of these two livelihood strategies. The relationship between remittances, pasture access, and livestock holdings is examined by analyzing 1,815 household surveys from southern rural Kyrgyzstan.

Heatwaves are the deadliest weather hazard and people and societies across the world continue to suffer from heat-related impacts. Future climate projections show a troubling increase in cross-sectoral impacts including health and economic risk presented by heatwaves. Many weather hazards such as floods and droughts already have a type of Early Warning System (EWS) or Global Alert System, but a global heat early warning system currently does not exist. An accurate heat EWS can save lives and can promote heat adaptation across society. Here, we (1) explore the history of Early Warning Systems as framed using the Disaster Risk Reduction paradigms and (2) identify potential barriers to an integrated Global Heat Early Warning system.
