The Federal University of Technology at Akure (FUTA) in Nigeria is experiencing ongoing development that leading to the replacement agricultural and forestry land cover types. This study aimed assess predict changes use/land (LULC) types their impact on crop characteristics 17 plots FUTA from 1991 2031. Crop were evaluated using normalized difference vegetation index (NDVI), water (NDWI), moisture (NDMI), condition (VCI), watershed delineation, spectral Landsat imageries. change modeler TerraSet software was used future LULC scenarios. Results showed an increase built-up areas (15%) bare (14%), but a reduction 19% light 2021. predicted map illustrated decrease area (11%) (19%) NDVI values denoting health coverage extent, NDWI & NDMI indicating stress soil palm tree (Plot 1) had highest average indices (0.31, 0.34, 0.06, respectively), while mixed cropping cassava, cashew, potatoes 6) lowest (0.23, 0.28, −0.029 respectively). indicates Plot 1 (palm tree) better with higher green canopy lower compared 6 (cassava, potato vegetation).

Assessing and predicting changes of ecosystem service values in response to land use/land cover dynamics in Ibb City, Yemen: a three-decade analysis and future outlook

International Journal of Digital Earth, Год журнала: 2024, Номер 17(1)

Опубликована: Март 11, 2024

Assessing ecosystem services values (ESV) within land use/land cover (LULC) changes is crucial for promoting human well-being and sustainable development of regional ecosystems. Yet, the spatial relationship between LULC still unclear in Yemen. This study aimed to assess impacts on ESV Ibb City, over three decades (1990–2020), predict 2050. The hybrid use classification technique classifying Landsat images, CA-Markov model prediction, benefit transfer method (BTM) assessment were employed. Our findings revealed that there was a continuous increase built-up areas barren land, with decrease cultivated grassland, which are predicted continue next 30 years. Consequently, total has decreased from US$ 68.5 × 106 1990 65.2 2020 expected further reduce 61.2 by 2050, reflecting impact urban expansion socio-economic activities ESV. provides insights future monitoring, will contribute formulation effective land-use strategies more services, particularly rapidly urbanizing data-limited regions.

We live in an urban planet. As the world continues to urbanize, development that support health and wellbeing of city dwellers is far more important than ever before achieve sustainable targets. This study explores complex relationship among planning, growth, as critical drivers rapidly growing nodal Akure, Nigeria.

The promptness of industrialisation and expanding urbanisation to achieve targets economics are resulting in the transfiguration permeable surfaces into impervious ones through LULC adaptation, leaving a herculean footprint on ecosystem. escalates land surface temperature (LST), which further stimulates urban heat islands (UHIs), ultimately remaining tune with high levels air pollution, energy use, corresponding health hazards. present evaluation first used Landsat TM/OLI satellite data identify labyrinth rotation and, secondly, gauged its effects LST Cachar district Assam, India, for years 1990, 2000, 2010, 2020. It embraces Cellular Automata (CA) GIS methodologies pull out urbanization pattern ramifications various brackets Cachar, India. also spatiotemporal monitoring (1990–2020) growth modelling (2030–2040).

This study provided insight into the size of difference between actual and predicted changes in Landsat 8 satellite imagery for case Sana’a Yemen. The LULC classification was created using data available 2005, 2010, 2015, 2020. It used MOLUSCE tool predicting land 2020, 2025, 2030. objectives this are 1) To compare 2010,2015 2) analyze verify tool’s performance (MOLUSCE). 3) identify effect which evented 2015 on 2020,2025 results were: 1/the effects 2010 showed accuracy reliability due to low before conflict region. 2/the were negative did not support logical trend toward progress where it is natural that human element progresses increasing construction. 3/identify prediction (2020,2025,2030) affected by events conflict, images.

The Mekong Delta faces significant challenges in supplying Vietnam and its export market countries with agricultural commodities, while ensuring livelihoods providing living space to growing population the context of climate change country's agrarian transition. Anthropogenic factors, such as construction dykes control river flooding, sand mining, further development triple-cropping rice production, infrastructure development, together impacts on sediment water availability, are all combining threaten production. One key sustainable is need identify plausible future states agricultural-based socio-ecological systems which draw upon differing strategies land management, characterise these both landscape employment. It was hypothesised from literature rapid rural appraisals that each system can only provide a certain number jobs, demonstrated using binomial regressions. We show odds being employed lower for intensive (OR=0.78 triple rice; 0.91 aquaculture) than diversified (OR=1.16 rice-aquaculture; OR=1.63 mixed fruit trees). Drawing workshops local national stakeholders, we then used Earth observation census data spatial use dynamic framework simulate two alternative futures based pathway RCP 4.5 combination existing policies (i) Resolution No. 124 (Specialisation) promotes crop aquaculture intensification (ii) 639 (Diversification), there should be diversification.
