Sazzad Hossain,&nbsp;Saida Islam Sejuti,&nbsp;Murad Ahmed Farukh","doi":"10.1002/geo2.70067","DOIUrl":"https://doi.org/10.1002/geo2.70067","url":null,"abstract":"<p>The Ganges-Padma floodplain of Bangladesh is a highly productive agricultural region critical to national food security and rural livelihoods. Over the past three decades, this fertile landscape has experienced significant land use and land cover (LULC) changes, particularly the expansion of agricultural land. This study analyses the spatial and temporal dynamics of such changes across six floodplain districts, namely Kushtia, Pabna, Rajbari, Chapai Nawabganj, Natore and Rajshahi from 1990 to 2023. Using Landsat imagery and a Random Forest classifier in Google Earth Engine, LULC maps were generated for five time points, achieving overall accuracies of 93%–99% and Cohen's kappa of 0.91–0.99. Findings reveal a net agricultural land gain of 771.70 km², primarily at the expense of water bodies (−634.23 km²) and vegetation cover (−224.71 km²). Change detection and transition-flow analyses show that wetlands and vegetated areas were the main sources of new cropland, driven by population growth, rising food demand and supportive agricultural policies. Built-up areas also expanded, though to a lesser extent. While agricultural growth supports food production, it has contributed to wetland degradation, biodiversity loss and heightened climate vulnerability. These trends underscore the urgent need for integrated land management strategies that balance agricultural expansion with ecological sustainability. The study offers critical insights for policymakers and planners aiming to promote sustainable land use in deltaic and floodplain regions.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"13 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://rgs-ibg.onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.70067","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147320820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While discussions about the impacts of climate change on food security, especially food crop production, are inconclusive, less attention has been given to cash crop production, which greatly contributes to the local economies of producing countries. Adapting agriculture to climate risks benefits from analysing trends and perceptions of climate change and its effects. This research examined the intersection of climate change and local perceptions, analysing climatic factors and their perceived impacts on small-scale cashew farming in Ghana. Using insights from the Jaman North District, primary data were collected from 250 cashew farmers through household surveys, 10 focus group discussions, and 5 key informant interviews. Trend analysis revealed a shifting start and end of the rainy season, an extended growing period, and increased rainfall (<i>p</i> &gt; 0.05) and temperatures (<i>p</i> &lt; 0.05). These findings supported smallholder farmers' perceptions of rising temperatures (98.4%), changes in the timing of the rainy season (99.6%), and rainfall variability (99.2%). The farmers reported experiencing various adverse effects from these climatic changes, including a decrease in household income (95.2%), lower cashew nut yields (90.0%), reduced market value (90.0%), and increased pest and disease pressure (85.2%). This study highlights the urgent need for adaptation strategies and policies to mitigate the adverse effects of climate change on vulnerable farming communities and to sustain cashew production in the region.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"13 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://rgs-ibg.onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.70061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147288296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Using Participatory Mapping to Strengthen Indigenous Resilience for Wildfire Risk: Lessons From Capoto/Jarina, Brazil","authors":"Michel Valette,&nbsp;Roiti Metuktire,&nbsp;Jayalaxshmi Mistry,&nbsp;Kokokrotire Metuktire,&nbsp;Yarika Juruna,&nbsp;Juliana Martins,&nbsp;Rafael Chiaravalloti,&nbsp;Juliana Bonanomi,&nbsp;Morena Mills","doi":"10.1002/geo2.70062","DOIUrl":"https://doi.org/10.1002/geo2.70062","url":null,"abstract":"<p>Indigenous lands in the Brazilian Amazon are critical to ecosystem conservation and cultural preservation but face increasing wildfire risks exacerbated by climate change and environmental degradation. This study explores how participatory mapping supports local resilience against wildfire risks, drawing on experiences from three villages in the Capoto/Jarina Indigenous land in Brazil. In each village, participatory maps were produced, and participants identified important locations for fire management, marking areas based on fire use, wildfire risks or the presence of fire-vulnerable resources. The results provide local insight into vegetation changes affecting wildfire and demonstrate how the interaction between vegetation and traditional fire use, including some small fires that are not detected by satellite, shapes wildfire risk. Results revealed the role of invasive plant species, such as <i>Brachiaria</i> spp., in shaping local wildfire risks. Participatory mapping helped pinpoint critical resources and vegetation types that are fire-sensitive and essential to local livelihoods. Finally, participatory mapping provided a spatially explicit representation of fire use, some of which were specific to environmental benefits, and wildfire risk management strategies across communities. The findings demonstrate that participatory mapping can help strengthen the resilience of local communities to wildfire risks by eliciting local fire use and wildfire management preferences while facilitating the creation of new local fire knowledge. The maps can be integrated into a broader wildfire risk assessment process, bringing together different knowledge systems to enrich stakeholders' understanding of shifting wildfire risks and planning for targeted interventions. As Brazil embraces the benefits of Indigenous and traditional fire use, participatory mapping can serve as a valuable tool for strengthening community-driven resilience strategies such as local fire brigade initiatives. Its accessibility and adaptability make it particularly effective for engaging diverse stakeholders, enabling greater participation and supporting the continuous adaptation of fire management practices in response to evolving environmental conditions.</p>","PeriodicalId":44089,"journal":{"name":"Geo-Geography and Environment","volume":"13 1","pages":""},"PeriodicalIF":3.8,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://rgs-ibg.onlinelibrary.wiley.com/doi/epdf/10.1002/geo2.70062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147288295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
