As the global community races to limit warming to well below 2°C in accordance with the Paris Agreement, Nature-based Solutions (NbS) have emerged as a critical, yet underutilized, pillar of climate change mitigation. While biophysical assessments suggest NbS can deliver up to 23.8 petagrams of CO2 equivalent per year, actual implementation in the voluntary carbon market (VCM) remains severely constrained. This original research paper investigates the intersection of economic viability and scientific readiness in determining the success of NbS projects. Utilizing a synthesized dataset of 150 hypothetical but empirically grounded NbS projects across Southeast Asia, Latin America, and Sub-Saharan Africa, this study develops a "Viability-Readiness Nexus" framework. Through multiple regression analysis, the paper tests how carbon pricing, monitoring and verification costs, scientific readiness scores, and land tenure security predict the actual volume of carbon credits retired. The findings reveal that scientific readiness (measurability, additionality, and permanence) and land tenure security are stronger predictors of project success than raw carbon market prices. Furthermore, high monitoring, reporting, and verification (MRV) costs act as a binding constraint, particularly for blue carbon and peatland restoration projects in Southeast Asia. The paper concludes that scaling NbS requires a paradigm shift away from pure market-based pricing toward integrated policy frameworks that subsidize MRV infrastructure, enforces standardized scientific assessments, and formalizes land tenure.

The global imperative to decarbonize energy systems has positioned green hydrogen as a cornerstone of the sustainable energy transition. Produced through water electrolysis powered by renewable electricity, green hydrogen offers a zero-carbon energy carrier capable of decarbonizing hard-to-abate industrial sectors, enabling long-duration energy storage, and enhancing energy security. This study presents a comprehensive comparative analysis of green hydrogen development across four distinct contexts: Kenya, Türkiye, India, and the Canadian province of Newfoundland and Labrador. Through an integrative framework examining technological readiness, policy architecture, resource endowment, and spatial sustainability, the research identifies both universal challenges and context-specific pathways for green hydrogen deployment. The findings reveal that while green hydrogen production technologies—particularly alkaline, PEM, and solid oxide electrolysis—have matured significantly, their commercial viability remains constrained by high capital costs, renewable electricity requirements, and infrastructure deficits. Policy analysis demonstrates that comprehensive national hydrogen strategies, demand-side incentives, and international cooperation frameworks are critical enablers, yet implementation gaps persist between ambition and execution. Spatial assessment of water stress and renewable energy potential in Türkiye reveals that high renewable potential regions coincide with severe water scarcity, necessitating seawater-based electrolysis approaches. The Kenyan case illustrates the importance of aligning green hydrogen development with existing renewable energy infrastructure and industrial decarbonization priorities. India's National Green Hydrogen Mission exemplifies large-scale ambition with targets of 5 million metric tonnes annually by 2030, while Newfoundland and Labrador's wind-to-hydrogen projects demonstrate the strategic value of proximity to European markets. The study concludes that successful green hydrogen deployment requires integrated approaches that simultaneously address technological innovation, policy coherence, infrastructure investment, spatial sustainability, and stakeholder engagement.

Mining activities exert profound and lasting impacts on terrestrial ecosystems, manifesting across multiple spatial and temporal scales throughout the mining lifecycle—from exploration and extraction to post-mining reclamation. This systematic review synthesizes current applications of remote sensing technologies and integrated assessment frameworks for monitoring mining-related environmental disturbances. Drawing upon an analysis of peer-reviewed literature, technical reports, and case studies from diverse geographical contexts—including Kazakhstan's limestone mining regions, Indonesia's quarrying operations, Ukraine's construction sector, and tailings storage facilities across Europe—the paper examines the utility of satellite-based Earth observation, unmanned aerial vehicles, and multi-criteria decision analysis in environmental impact assessment. The review demonstrates that remote sensing indicators—particularly the Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), and Land Use/Land Cover (LU/LC) change detection—provide reliable measurements of vegetation degradation, thermal anomalies, and landscape transformation associated with mining operations. Findings indicate that limestone mining commonly leads to 40-60% reduction in vegetation density and LST increases of 1.5-3.0°C in disturbed areas. The integration of the DPSIR (Driving Forces-Pressures-State-Impacts-Responses) framework with geospatial technologies offers a comprehensive approach to understanding the causal relationships between mining activities and environmental degradation. The review further identifies that tailings storage facility monitoring through integrated Life Cycle Assessment and Environmental Risk Assessment frameworks can quantify risk reduction potential, with smart monitoring solutions reducing failure probability from 18.9% to 13.6% and achieving measurable life cycle improvements. Challenges persist regarding data quality, model transferability, and the characterization of complex subsurface disturbance mechanisms. The paper concludes by proposing an integrated framework that combines multi-resolution remote sensing data, surface-subsurface observation coordination, and explainable artificial intelligence to support evidence-based environmental governance in mining regions.

As the global community races to limit warming to well below 2°C in accordance with the Paris Agreement, it is increasingly evident that decarbonizing the energy sector alone will be insufficient. Nature-based solutions (NbS)—encompassing the conservation, restoration, and improved management of natural ecosystems—have emerged as a critical, yet underutilized, pillar of climate change mitigation strategies. This paper synthesizes current research to evaluate the biophysical potential, economic viability, and scientific rigor required to scale up NbS effectively. By examining global mitigation pathways, including terrestrial "green" carbon, "blue" coastal carbon, and peatland ecosystems, this review highlights that NbS can deliver upwards of 10 to 23.8 petagrams of CO2 equivalent per year. However, realizing this potential is constrained by complex economic dynamics within voluntary carbon markets, particularly issues of additionality, leakage, and permanence. Furthermore, the paper explores a two-stage scientific assessment framework designed to evaluate the "readiness" and "sufficiency" of novel mitigation activities. The findings suggest that while NbS face rising opportunity costs and competition from increasingly cheap energy-technology-based solutions (ETbS), their unique "double dividend" of delivering biodiversity conservation, water security, and rural livelihood benefits justifies sustained investment. The paper concludes that scaling NbS requires robust scientific standardization, innovative financing mechanisms beyond carbon credits, and integrated policy frameworks that align ecological boundaries with economic realities.

Climate change acts not merely as an environmental stressor but as a profound amplifier of existing socioeconomic inequalities, particularly in the Global South. This research paper synthesizes empirical findings from four critical regions—the East African Community (EAC), Bangladesh, Nepal, and Zimbabwe—to explore the intersecting dynamics of climate vulnerability, rural-urban infrastructure disparities, and governance challenges. Drawing on comparative case studies, this paper examines how climate stressors differentially impact rural and urban populations, the efficacy of national adaptation policies, and the resulting socio-economic outcomes, including agricultural transformation and forced migration. Findings indicate that rural areas consistently bear the brunt of climate impacts due to infrastructure deficits, lower socio-economic capacity, and delayed policy implementation. In the EAC, climate variability widens rural-urban electricity gaps, severely constraining agricultural modernization. In Nepal, environmental degradation forces rural exodus and migration, while in Zimbabwe, a distinct rural-urban divide in climate awareness dictates divergent adaptation strategies. Meanwhile, Bangladesh exemplifies the complexities of climate governance, where robust national policies frequently falter at the implementation stage due to institutional fragmentation. The paper concludes that effective climate adaptation requires a paradigm shift: infrastructure must be treated as climate adaptation, governance must be decentralized and coordinated, and localized education must bridge the awareness gap. Without spatially targeted, institutionally coherent interventions, the global commitment to "leave no one behind" remains an unfulfilled aspiration.
