Achieving zero waste for landfills by employing adaptive municipal solid waste management services

Ecological Indicators, Journal Year: 2024, Volume and Issue: 165, P. 112191 - 112191

Published: June 3, 2024

Amidst global pushes for sustainable land development, Jakarta confronts pressing municipal solid waste management (MSWM) issues, with limited landfill capacities and rampant illegal dumping in slum non-slum areas, exacerbating consumption challenges. This context underscores the urgency to explore adaptive MSWM strategies that align broader planning objectives. research aims distinguish shed light on preferences of Jakarta's residents. The emphasis is placed their importance-performance (I-P) related strategies. An in-depth evaluation involved twelve indicators across five capacity dimensions, correlating them I-P metrics participant demographics. Both communities underscored importance bolstering circular economy segregation. However, a pronounced awareness regarding treatment was observed among On other hand, individuals from locales indicated greater need focused encouragement resources engage segregation initiatives effectively. insights this study are pivotal urban planners, policymakers, scholars. Recommendations span instituting self-reminder systems, enhancing collection services, ensuring strict regulatory compliance endorsing bank participation mobilizing local community leaders, or cadres, lead endeavors. By fostering harmonious ecosystem, smart cities like can ensure equitable progressive all its residents, thus moving closer future.

Urban land management under rapid urbanization: Exploring the link between urban land policies and urban land use efficiency in Ethiopia

Cities, Journal Year: 2024, Volume and Issue: 153, P. 105269 - 105269

Published: July 16, 2024

Ethiopia's rapid urbanization over the past two decades has led to conversion of agricultural land urban use. However, this expansion been largely unplanned, resulting in numerous management challenges. These gaps have hindered efficient use, a critical component sustainable development. This study examines impact current institutional environment on use efficiency (ULUE) Ethiopia and explores why policies not translated into effective practices. Using case approach qualitative method, research identifies factors that influence ULUE, drawing Institutional Analysis Development (IAD) framework Credibility thesis. The several contribute low including an inefficient transfer market, tenure insecurity hoarding. problems are exacerbated by policy formulation implementation, inadequate human technical capacity, unrealistic spatial planning, weak governance. To improve security discourage hoarding essential. Addressing shortcomings legal strengthening governance capacity key steps.

Spatiotemporal analysis of urban expansion and its impact on farmlands in the central Ethiopia metropolitan area

Discover Sustainability, Journal Year: 2025, Volume and Issue: 6(1)

Published: Jan. 17, 2025

Urban growth in sub-Saharan Africa presents significant challenges to sustainable development, food security, and environmental conservation. The rapid urban expansion impact on agricultural land reduction central Ethiopian metropolitan areas (Addis Ababa Sheger city) exemplify these issues while simultaneously offering opportunities for development. This study aims quantify characterize the spatiotemporal dynamics of Addis surrounding city, explicitly focusing understanding farmlands. supervised random forest (RF) classification Google Earth Engine platform was used prepare use cover (LULC) 1990, 2000, 2010, 2023. employed an analytical framework incorporating multiple methodologies: intensity analysis at interval, categorical, transitional levels trajectories; gradient direction distance analyses examine spatial patterns; Land Expansion Index (LEI) Landscape Dynamic Typology (LDT) metrics morphology area. results revealed that edge is predominant mode primarily affecting farmlands eastern section. Built-up quadrupled between 1990 2023, whereas arable declined. Intensity changes, particularly Our LDT showed stable increased LULC changes from findings highlight need revised development strategies Ethiopia focus compact efficient safeguarding lands, aligning with SDGs 2, 11, 15 promote balanced ensures sustainability.

Driving forces and prediction of urban land use change based on the geodetector and CA-Markov model: a case study of Zhengzhou, China

International Journal of Digital Earth, Journal Year: 2022, Volume and Issue: 15(1), P. 2246 - 2267

Published: Dec. 19, 2022

Exploring urban land use change is a classical problem in geography. Taking Zhengzhou as an example, this paper analyzes the spatial and temporal characteristics driving factors of change, simulates pattern future. The results study show that types city were mainly farmland construction land, area forestland, grassland, water area, unused was smaller, main transformation into land. accuracy check simulated type data 2020 showed kappa coefficient reached 0.9445, which met requirement. Then, according to predicted 2025, it found may have decreased, farmland, forestland increased. Based on force analysis changes, its prediction can provide important reference basis for formulation planning policies related construction.
