Understanding the ecological, social, and economic values of protected areas, as well assessing services they provide to both humans environment is crucial for informing conservation policies sustainable land management practices. Using benefits transfer method, changes in ecosystem service (ESVs) resulting from spatiotemporal use dynamics were evaluated Alledighe Wildlife Reserve (AWR) spanning 1998 2016. Five distinct habitat types, namely grassland, bushland, woodland, riverine forest, highland identified across landscape. The ESVs estimated using regional global ESV values. A decline extent forests by 9.9%, 2.4%, 1.5%, respectively, was observed while bushland increased 10.6% 3.3%, respectively. AWR experienced a loss roughly 145 km2 grassland habitat. Based on ESVs, total study area decreased 28.18% approximately US$ 180 million 129 million, 40.85% 496 293 million. As per individual assessment, 41% around 374.5 264.8 Provisioning declined 41.6% 100 70.6 Regulating 42.5% 242.4 170 Supporting 67% 5.3 3.2 cultural 27.8% 26.7 20.8 larger change contributed expansion forestland previously grassland-dominated areas. results this could render value rangeland more visible decision-making process, valuable input future planning interventions AWR's pristine rangeland, thereby enhancing livelihoods surrounding communities.

Accounting of carbon sequestration and tradeoff under various climatic scenarios in alternative agricultural system: a comprehensive framework toward carbon neutrality

Frontiers in Sustainable Food Systems, Journal Year: 2024, Volume and Issue: 8

Published: May 10, 2024

Introduction The increase in atmospheric CO 2 concentration, which mainly is attributed to fossil-fuel combustion and deforestation, often suggested as one of the prime causative factors toward accelerated global warming. This commends for sequestration carbon under terrestrial systems partially offset emissions. Concerning same, agricultural sector presents an extensive opportunity, especially countries such India where over 55% population engaged agriculture sector. Methods Sequestering requires adoption climate-resilient alternative practices without compromising food security. deliberated study highlights options alteration current conventional farming its economic evaluation sequestrating two Climate Change (CC) scenarios, viz. , RCP 4.5 8.5, three temporal scales, i.e., 2020, 2030, 2050. Considering land-use pattern existing growth rate shifting, policies, namely, Business Usual (BaU), Optimistic, Pessimistic scenario, integrated with CC scenarios were contemplated. Six possible futuristic generated assessment valuation following Integrated Valuation Ecosystem Services Tradeoff (InVEST) model. Results results that across studied region adopting optimistic policy BaU pessimistic can sequestrate additional 0.64 1.46 Mt. (2.35 5.36 million ton e) having value 193.4 504.8 USD. Moreover, outcomes are advocated credit sector, shall contribute meeting various nationally determined contributions (NDCs) sustainable development goals (SDGs) well.

The impact of land use and land cover changes on ecosystem service value in Aceh Besar Regency, Aceh, Indonesia

Bulletin of Geography Physical Geography Series, Journal Year: 2024, Volume and Issue: 26, P. 69 - 76

Published: June 10, 2024

Land use and land cover (LULC) have a significant impact on changes in the value of ecosystem services. Therefore, this study investigated relationship between service (ESV) LULC Aceh Besar Regency by calculating nine ESV variables, namely gas regulation (GR), water supply (WS), soil formation (SF), waste treatment (WT), biodiversity protection (BP), food production (FP), raw materials (RM), recreation (RC), culture (CT) each type three years: 2000, 2010 2020. The results showed that both decades saw all years, there was decrease forest due to addition activities population needs, resulting conversion into built-up areas. This indicates is change human potential negatively affect

Impacts of land Use/land cover dynamics on ecosystem services in Jimma Rare District, Western Ethiopia

Sustainable Environment, Journal Year: 2024, Volume and Issue: 11(1)

Published: Dec. 12, 2024

Land use/land cover (LULC) change is one of the most important environmental phenomena that have affected earth's system and its ecosystem services. This study was conducted to assess impacts LULC on services in Jimma Rare district for over four decades (1974–2019). To understand spatial temporal changes LULC, a four-time period satellite images (1974, 1991, 2005, 2019) were obtained. In addition, respondent interviews, focus group discussions (FGD) field observations employed identify drivers land use changes. Moreover, service value coefficients developed at global level used provision area. The showed grassland decreased from 4518.87 ha (13.09%) 902.42 (2.61%), forest 3287.79 (9.52%) 2506.63 (7.26%) wetlands 1182.08 (3.42%) 562.37 (1.63%) period. remarkable expansion cultivated settlement area occurred 1974 1991. total reduced 662.75 million $/ha/yr 577.03 period, indicating impact values. From this study, it possible conclude District has experienced significant past 45 years. Hence, appropriate policy packages are required curb such vital thereby enhancing sustainable flow district.
