Abstract

Climate change is a significant threat to agricultural productivity, particularly in underdeveloped countries where rain-fed farming is common. Without adaptation, climate change may negatively impact agricultural productivity; however, adopting adaptive measures can reduce vulnerability and potentially increase some of the benefits of climate change. This study explores the sociocultural factors that influence farmers in Oromia's Berbere district to select particular adaptation strategies. We gathered information from 339 randomly chosen smallholder vegetable growers. We used a multinomial logit model to examine the variables affecting their selection of adaptation measures. The findings showed that the adoption of vegetable diversification strategies was significantly influenced by factors like family structure, the transmission of indigenous knowledge, land tenure and cultural ties, access to credit, communal trust systems, cultural perceptions of climate change, and farming experience. The dissemination of indigenous knowledge, adoption of technology, cultural acceptance, financial availability, community trust, and non-farm revenue were also important elements that favorably impacted the selection of varietal adaptation strategies in the region. The decision to modify planting dates in response to climate change was also greatly influenced by elements such as indigenous knowledge transfer, land tenure and cultural attachment, technology adoption, cultural interpretation of climate change, and farming experience. The adoption of spatial risk distribution as a climate change adaptation strategy was found to be negatively impacted by the distance to agriculture, whereas family structure, land tenure, and cultural connection emerged as significant positive characteristics in this location. In order to adapt to climate change, irrigation methods are greatly influenced by a number of factors, including family dynamics, the speed at which we adopt new technology, cultural attitudes, understanding of climate change, and income from nonfarm sources. This emphasizes how important it is for legislators to incorporate these components into household-level climate adaptation plans.

Abstract

This study investigates long-term climate variability and land-use dynamics in the Ife Region of Southwest Nigeria using an integrated, multi-source geospatial framework spanning 1984-2024, addressing persistent data limitations in the region. Meteorological data, including daily and monthly rainfall and temperature records, were obtained from the Climate Hazards Group InfraRed Precipitation (CHIRPS) and ERA5-Land datasets, respectively and complemented by satellite-derived variables NDVI, land surface temperature (LST), and land-use/land-cover (LULC) acquired from Landsat (TM, ETM+, OLI/TIRS) imagery of 30m resolution. Accuracy assessments were conducted for all classified years to ensure the reliability of the results. Results show a mean air temperature rise of about 1.24°C over the study period, equivalent to a trend of +0.031°C per year, alongside a progressive increase in annual rainfall at +7.28mm per year. LST intensified significantly, increasing by 3.6 - 5.2°C in urban areas and 2.1 - 3.4°C in rural areas. Vegetation condition weakened markedly, with peak-season NDVI decreasing from 0.68 in 1984 to 0.42 in 2024, indicating heightened vegetation stress. LULC analysis revealed extensive spatial transformation: Undisturbed Forest declined by 540.05km² (-56.95%), while Farmland and Built-up Areas expanded by 253.87 km² (+95.47%) and 124.23 km² (+38.40%), respectively. Classification reliability remained consistently strong, with Overall Accuracy values ranging from 93.5% to 96.1% and Kappa coefficients of 0.90–0.95. The regression model explains 86.9% of LST variability in the Ife Region (R² = 0.869; F(6, 45) = 50.05, p < 0.001), with temperature (β = 0.789), Built-up Areas (β = 0.321), and forest cover (Undisturbed: β = –0.266; Disturbed: β = 0.198) as main drivers. Urbanisation and forest loss increase warming, while intact forests and rainfall (β = –0.178) provide cooling, highlighting the combined effects of land-cover and climatic factors on surface temperatures. These interacting shifts heighten ecological stress, influence hydrological stability, reduce agricultural resilience, and amplify urban heat conditions.

Abstract

Before taking any meaningful public action to reduce poverty in Ethiopia’s rural areas, it is necessary to comprehend how rural households see their situation. Hence, the major objective of this study was to look into the indigenous view of rural households and poverty. Through an organized interview schedule, pertinent data were gathered. The collected data were measured using the Rotated Component Matrix, Score Coefficient Matrix, Eigenvalue-One Criterion, Bartlett’s Test of Sphericity, and Kaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO). Thus, analysis showed that a rural household is considered to be poor when they are with wage workers, have a large number of children, a female head of household, migrate, have little to no grain stock, have poor information-seeking habits, have subpar clothing, subpar fencing, subpar housing, have fewer plough oxen, have fewer livestock, have a low level of education, are unable to transport their members to the health center, have inadequate savings, are not close to all weather roads, do not use extension agents, do not use agricultural inputs, and do not utilize credit service. In conclusion, rural households’ indigenous perspectives on poverty should be acknowledged and valued and that efforts to alleviate poverty should be implemented based on these perceived markers of poverty.

Abstract

Lake Chad Basin (LCB) terrain has long been a lifeline for a large number of people who rely on it for agriculture, fishing, and livestock production. However, its water resources have come under severe stress due to a combination of climate variability, environmental degradation, and persistent insecurity driven by the Boko Haram insurgency and related conflicts. This study examines the effect of security challenges on water accessibility within the portion of the LCB. Using a mixed-methods approach that combined questionnaire surveys, focus group discussions (FGDs), and key informant interviews (KIIs), the research assessed the extent to which insecurity, insurgent activities, and environmental factors disrupt water availability, access, and infrastructure. Findings reveal that insecurity significantly limits community access to water points, disrupts agricultural activities, and contributes to displacement, thereby heightening food and livelihood insecurity. Moreover, insurgent attacks have destroyed water infrastructure, restricted transhumance flows, and forced communities to abandon traditional water-use practices. While some adaptive strategies exist, they remain insufficient, costly, and unsustainable. The study concludes that without integrating water management with peacebuilding, infrastructure protection, and community resilience strategies, achieving sustainable water accessibility in the LCB will remain elusive

Abstract

Green Open Space is an important aspect in regional spatial planning. Lack of availability of Green Open Space can cause environmental problems such as increasing ground surface temperature. The purpose of this study was to analyze the Availability of Green Open Space using Sentinel-2A Imagery in Jember City Area in 2019 and 2024, and to analyze Land Surface Temperature using MODIS Imagery and Sentinel-2A Imagery in Jember City Area in 2019 and 2024. The type of research used is quantitative using a survey method. The sampling technique used purposive sampling with data collection techniques through observation and documentation. The data analysis technique used quantitative descriptive analysis techniques. The research data is presented in the form of a map using the NDVI method for Green Open Space and the LST method for Land Surface Temperature which is processed using Google Earth Engine. The results of this study indicate that the Availability of Green Open Space using Sentinel-2A Imagery in 2024 has been well available, namely 52% of the total area of ​​Jember City, while in 2024 the Availability of Green Open Space was 42% of the total area of ​​Jember City. Furthermore, the results of processing the distribution of Land Temperature using MODIS Imagery and Sentinel-2A Imagery in 2019 and 2024 show that the temperature in the City area is dynamic so that it can change at any time, this is influenced by natural conditions, physical conditions of the area, climate, weather, and hydrology. The highest temperatures tend to be in the city center which then spreads spatially to the outskirts of the Jember City area.
