Published: March 16, 2023

Introduction Management of coastal wetlands has resulted in extensive conservation this natural resource; however, changes carbon storage function are not yet known. There is a direct link between landscape and soil storage. Predicting future the important for developing wetland management policies. Method Here, remote sensing physical methods were used to measure calculate surface stocks Liaohe River Estuary Wetland (LREW). The under three scenarios: development, strict protection, culture pond transfer, then predicted using PLUS model. Result results indicate that organic was 2107.97×103 t, while density decreased from land sea. Anthropogenic activity found be main driver current evolution. However, impact sea level rise increasing. By 2030, considerably more will gained transfer scenario than at present. Discussion Our reveal some ecological restoration may diminish capacity wetlands. Making full use areas with high potential an effective sink strategy. Governments should consider comprehensively better pool when strategies.

Published: Sept. 3, 2024

In light of international climate agreements and the Sustainable Development Goals (SDGs), there is a growing need to enhance understanding linkages among land use/cover change (LUCC) its carbon effects (CEs), as well human well-being (HW). While existing studies have primarily focused on impacts LUCC CEs or ecosystem services, remains gap in systematically elucidating complex relationships LUCC, CEs, HW. This paper presents comprehensive review nexus between land-based HW, examining: (1) correlation encompassing methodologies for investigating CEs; (2) association introducing concept “low-carbon well-being” evaluation framework; (3) proposed framework “LUCC-CEs-HW,” which delves into intricate connections three elements. The study identifies research gaps outlines potential future directions, including assessments low-carbon exploration “LUCC-CEs-HW” nexus, development standardized measurement approaches. Key opportunities further investigation include establishing unified index system developing scalable methods. elucidates offering insights works.

Mediterranean urban areas are reportedly affected by poor air quality due to numerous emission sources, as well topography and meteorological conditions that facilitate the accumulation of pollution. This present study makes an initial attempt assess effect gaseous pollutants (NO2, CO, O3) particulate matter (PM2.5 PM10) on Nador city, which lies coast Morocco. Three daily, short-term sampling campaigns were conducted between 2016 2018 in area. The concentrations PM2.5 PM10 together with elemental compositions (up 16 elements) black carbon content determined. obtained data characterized using descriptive analysis, correlation matrices, enrichment factors (EFs), ratios. On average, pollutant below national standard limits. Two categories derived from EF investigation, defined soil/crustal (Ti, Al, Mn, Sr, K, Na, Ba, V) anthropogenic (Ni, Cr, Cu, Zn, Pb). For carbon, biomass burning was found be largest contributing source (3.1–8.4 µg m–3), more so than fossil fuels (0.9–1.8 m–3). highlights management plan should established for including implementation a network monitoring stations help identifying controlling activities causing
