The escalating pace of migration and urbanization in Nepal has triggered profound alterations land use practices. This event resulted a considerable diminution ecological diversity substantial decline the potential for carbon sequestration other ecosystem services, thereby impeding climate change mitigation efforts. To address this, comprehensive assessment storage was conducted from 2000 to 2019 forecasted 2050 Nepal. Employing Markov chain InVEST models, this study evaluated loss gain carbon, elucidating its economic value spatial distribution. findings revealed that were 1.237 1.271 billion tons, respectively, with projected increase 1.347 million tons by 2050. Carbon between amounted 34.141 which is anticipated surge 76.07 2050, translating valuations 110.909 378.645 USD, respectively. Forests emerged as pivotal storage, exhibiting higher pooling than types, expanding 37% 42% total area predicted year Notably, distribution concentrated parts terai mountain regions, alongside significant portions hilly terrain. offer valuable insights governing REDD+ developing implementing forest management policies. results emphasize importance providing incentives local communities judiciously promote effective conservation measures.

The rapid expansion of informal settlements poses significant challenges to urban ecosystems and their services, a pressing issue that this study addresses by examining its impacts in Addis Ababa. This delves into the impact on ecosystem services Ababa, comparing them with formal settlements. Utilizing geographic information systems (GIS) remote sensing, it employed Landsat imagery, aerial photography, base maps track spatiotemporal changes analyze trends. Through GIS overlay approach, associated land use were identified, while benefit transfer method assessed service values. findings revealed increase city's outskirts, expanding from 77 ha 2009 (2% total area) 765.6 2023 (21% area). Nearly half (48.5%) these established previously natural covers through encroachment. research highlighted ongoing conversion agricultural land, forests, green spaces settlements, particularly leading encroachment areas. transformation caused an annual loss $1,665,033.7 2023. Significant identified food production, climate regulation, habitat services. Overall, due amounted $1,933,320.08. Informal accounted for 86.1% loss, highlighting urgent need targeted interventions mitigate disproportionate effects underscores urgency addressing effective planning, sustainable management practices, prevention covers, promotion utilization.

Wetlands are among the most valuable natural resources on Earth. However, many have been destroyed in recent decades. One suggested solution for their sustainable use is creation of collective management and protection strategies. These measures would involve stakeholders at various levels. Therefore, this study, encapsulation model social identity action used to increase understanding how participation wetlands strengthened. The aim study was examine farmers' willingness engage activities Helleh Wetland. To achieve this, a cross-sectional survey conducted farmers living near Wetland Iran. results indicated that effectively explained intentions participate wetland. According results, negative emotions had significant relationships with intention toward protection. Similarly, efficacy also found be related using motivate wetland can effective. approach will successful if environmental authorities prioritize addressing removing past experiences participation. This offers insights into socio-psychological factors influence conservation. findings provide implications managers, policymakers, decision-makers, helping them encourage

The prioritization of is essential start a decision-making process focused on environmental policies, highlighting the necessity equilibrium between sustainability human well-being. This study analyzes similarities differences among provided by Spanish RAMSAR wetlands, where rice production main economic activity. These areas Ebro Delta, Albufera Natural Park Guadalquivir Marshes (Doñana Biosphere Reserve). Despite different areas, agricultural policies sometimes treat their characteristics without distinction since they conceptually englobed in same category. analysis aims whether geographical sociocultural factors could influence services. three was conducted using Analytic Network Process (ANP), multi-criteria method which allows decision-makers manage ecosystem's complexity. results helpful for future understanding complex network interconnections Additionally, show that there statistically significant priorities due cultural reasons. Moreover, have also shown decision-makers' judgements influenced depending background personal or professional preferences. It emphasizes implementing from theoretical global scale participatory local one, considering broader range stakeholders' perceptions reflect complexity network.
