Evaluating the impacts of land use/land cover (LULC) change on ecosystem service values (ESVs) is critical for understanding implications use human well-being, identifying trade-offs and synergies between different services, monitoring changes in health, informing decisions planning conservation efforts. As a result, this study aimed to examine effects these ESVs during last four decades (1984-2022) predicted periods 2040 2060 by utilizing combination geoinformation, economic evaluation approaches. The modified value (ESV) coefficients were used estimate influence LULC ESVs. result revealed that overall ESV has declined from US$390 × 106 1984 US$273.21 2060. However, various services varied, with certain such as crop production, pollination, biological control, increasing value. These findings also emphasized necessity evaluating it depicted may be possible retain or improve even face declines total Subsequently, study, therefore, give important insights policymakers, managers, local people devising appropriate policies plans well realizing, implementing sustainable practices ensure provision essential future generations.

Опубликована: Фев. 12, 2024

For the preservation of ecosystems, including enhancement ecological strategies, examining temporal and geographical variance in ecosystem services (ESs) land use/land cover change (LUCC) is crucial. Gannan situated on upper Yellow River, which a notable water conservation region with excellent quality, but background local traditional production mode rapid economic development, natural disasters, grassland degradation, other problems occur frequently. The integrated valuing tradeoffs (InVEST) model patch-generating use simulation (PLUS) are combined this work to assess spatiotemporal ESs Gannan. We set up three scenarios modeling future use—ecological protection (EP), development (ND), (ED) 2050—and analyzed evaluated drivers variation ESs. In order reveal LUCC between 1990 2020, we predicted spatial distribution characteristics 2050, explored correlation its driving factors, comprehensively propose optimization measures strategies. Through several experiments, findings indicate following: (1) largest percentage expansion for construction 2020 74.53%, most noticeable shrinkage sand area 20.67%; (2) from Gannan’s yield, carbon storage, soil retention, habitat quality all changed, by 60 × 108 m3, 0.04 t, −10.66 −0.02, respectively; (3) influenced variety societal variables: southern southwestern regions home majority hot spot areas, while northern cold areas. This study contributes analysis developmental traits ecosystems can serve as terrestrial comparable environmental traits.

Impacts of land use and cover changes on ecosystem service values from 1992 to 2052 in Gena District, Southwest Ethiopia

Scientific African, Год журнала: 2024, Номер 24, С. e02244 - e02244

Опубликована: Май 7, 2024

Land use and cover changes alter the functions structures of ecosystem, resulting in variations Ecosystem Service Values (ESVs). Thus, we examined impacts land use/land (LULC) on ESVs from 1992 to 2052 using geospatial technologies. The Landsat images were classified supervised maximum likelihood classification technique, future LULC predicted CA-Markov model. adopted empirical studies their evaluated based benefit transfer method data for study periods, with corresponding modified coefficients. results revealed that, proportions grassland, forestland shrubland declined by 58.5%, 48.15% 33.48%, respectively, 2022. Simultaneously, highest rate expansions waterbodies (34 times), farmland settlement threefold as well bareland (60.2%) 2022 was noticed. As a result, decreasing trends experienced total district US$33.6 million US$27.79 2022, are anticipated further decline US$25.94 2052. forestland, grassland shrank 53.1%, 40% 2.78% 33.28%, 33.16% 1.4% these continue next three decades, except trend increase ecosystem service value. Therefore, government should redesign effective management strategies alleviate negative consequences changes, facilitate payment services, design ecotourism boost income residents major management-based production systems ESV district.

This study investigated water safety practices and risk levels along Addis Ababa’s supply service chain. The data came from 23 random woredas, 384 households, 115 microbiological quality tests, diagnostic inspections source to point of use. Findings this indicate that the surface sources (53%) catchments (62%) are characterized by very high-risk high contamination respectively. Conversely, treatment process (5%) temporary reservoir (20%) indicates a low level. Whereas distribution system (40%), boreholes (44%), Household level (29%) identified as medium levels. microbial analysis drinking at use indicated (<11 CFU/100 ml) (>100 with significant household Moreover, household-level practice assessment revealed intermediate risks. Chi 2 test shows type is significantly associated occupation(X2(12,384) = 23.44, P < .05) education(X2(8,384) 15.4, .05). Multinomial regression also showed better occupation increased access safe bottled compared piped on premises. It can be concluded encountered different components chain suggests ways improve Ababa residents’ health well-being through interventions. These include safeguarding sources, supporting local businesses, providing treatment, handling options, addressing barriers incentives for adopting practices.

Landscape change is intricately linked to natural resource utilization. dynamics are closely tied land use and cover (LULC), serving as a representation of ecosystems human activities. In the Citarum River Basin, Indonesia, comprehensive approach necessary comprehend landscape manifestation interaction with environment. This research aims analyze its factors that can significantly drive changes. We focused on Cirasea Watershed, which serves an upper region Basin. Data was acquired from Landsat-series imageries 1993 2023, LULC analyses were conducted using classification regression trees (CART), random forest (RF), support vector machine (SVM). analyzed seven independent variables, including slope (X1), elevation (X2), main river (X3), population (X4), central business district (X5), distance past settlements (X6), accessibility (X7) multivariate analysis. found RF stands out optimal choice for analysis over CART SVM because it had highest overall accuracy kappa (0.91–0.92, 0.88–0.89). Notably, there substantial 273.43% increase in built-up areas, coupled significant declines plantations horticultures. changes more pronounced lower areas near Bandung City. LR model highlighted X1, X3 X6 driving forces expansion (r-square 0.44 p-value < 0.01 95% confidence level). Without effective spatial planning, flat rivers have greatest potential
