While social media can speed up disaster information, false information causes anxiety, fear, and poor decision-making, which affect preparedness and resilience. This study describes how local capacity building can address false information in community-based disaster risk management. The research uses a qualitative approach with secondary data analysis and an integrative literature review. The findings of this study show that there is a need to strengthen local capacity building to prevent the spread of false disaster information to communities and interested parties. The current response to misinformation in disaster situations includes digital literacy and media literacy education to help individuals assess news sources and verify information. It also includes community-based training programmes focusing on disaster preparedness, response, and communication, aiming to reduce the impact of misinformation. Establishing local communication networks, such as community radio stations or messaging groups for reliable alternatives to social media, is also critical to address misinformation. The study also found that trusted local leaders and influencers ensure accuracy, and transparent official channels promote public trust. Furthermore, simulated drills and workshops teach information verification practices, preparing communities to manage misinformation during crises. These efforts, along with local capacity building, are essential in strengthening community resilience and improving disaster management practices.</p><p><strong>Contribution: </strong>This study contributed to improving disaster management communication with local communities.

This study focusses on increasing our understanding on the ability of smallholder farmers in Karonga, Malawi, to adapt to climate variability. To achieve this, an integrated framework was used to assess the factors that influence the adaptive capacity of smallholder farming systems in Karonga. The integrated indicator-based framework was used to assess financial, social, human assets, knowledge and information, institutions and entitlements, flexible and forward-looking decision-making, gender and power dynamics, natural assets, physical assets and the frequency of floods. Data were collected through face-to-face interviews, focus group discussions and observations. A total of 38 indicators from literature and observations in the study area were entered and analysed in SPSS and Excel using principal component analysis. The survey results indicate that the aggregate adaptive capacity of respondents is low. Component indicators, such as ownership of livestock, support from the community, livelihood diversification and gender of the decision maker, as well as access to a mobile phone and inorganic fertiliser, and share of more productive land, increased the adaptive capacity of smallholder farmers.

Historical knowledge of hazard occurrence stored in the repository of these communities combined with their ability to observe environmental indicators, enhances their preparedness for, response to, and recovery from disasters. This study sought to gain insights into the Indigenous indicators used by rural communities in the Joe Morolong Local Municipality, Northern Cape, South Africa, to predict natural hazards, and explores how these indicators could complement meteorological seasonal climate and weather forecasts. The study was conducted in Joe Morolong Local Municipality, Northern Cape, South Africa. A phenomenological approach, which is a form of qualitative research design, was employed, with data collected through focus group discussions and virtual interviews with key informants, involving 109 participants. The findings reveal that communities rely on various environmental signs, including changes in vegetation, lunar cycles, cloud formations, bird behaviors, and wind speed and direction, to predict and anticipate hazardous events. These traditional methods, refined over generations, provide localised, trusted, and contextually relevant early warning systems that enhance disaster preparedness. By recognising and integrating these Indigenous indicators with meteorological forecasts, disaster risk management efforts can be strengthened, ensuring that rural communities have more comprehensive and effective tools for mitigating the risks and impacts of natural hazards.</p><p><strong>Contribution: </strong>This study emphasises the value of Indigenous knowledge as a vital resource for enhancing disaster and climate resilience, as well as improving early warning systems.</p>","PeriodicalId":51823,"journal":{"name":"Jamba-Journal of Disaster Risk Studies","volume":"17 1","pages":"1754"},"PeriodicalIF":1.3,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12067527/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144052009","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}

In light of this, the study aimed to assess organisations' capacity and obstacles to collaborative approaches for adapting and building resilience to climate change-induced extreme weather events. Primary data were collected through a questionnaire distributed among 25 organisations, involving 325 participants. Thematic analysis was employed for qualitative data analysis, and the analytical hierarchy processing (AHP) method was applied to analyse intra-organisational challenges or obstacles to adopting climate resilience strategies. Alarmingly, 90% of organisations suspended operations because of climate-related disasters, with only 5% engaged in flood mitigation approaches. About 67% lacked flood abatement measures, and only 4% had conducted risk assessments. Most enterprises relied on government (80%) and Non-governmental organisations (NGOs) (70%) for resilience. Additionally, 85% of the organisations did not act collectively during extreme weather events, facing challenges such as lack of planning, adaptive capacity, leadership and funding.
