Introduction Floods are classified as one of the hydrological hazards affecting many countries worldwide. With most weather-related disasters occurring in developing countries, demographics and socioeconomic pattern changes have contributed to many losses relating to water-related disasters such as floods. South Africa is among the developing countries most frequently affected by natural disasters, particularly floods. Thus, this study assessed the causes and impact of floods on the communities of Bronville and Hani-park in Welkom in the Free State Province in South Africa.Methods The study adopted a quantitative approach, using a structured questionnaire to collect the data. The study used an R statistical package to analyze the data and applied descriptive statistics and a series of Generalized linear models to examine the impacts of floods in the community.Results The findings reveal a community-wide concern about flooding impacts. There was a statistically significant difference between whether floods affected your physical structure as an outcome variable and how the flooding affected participants (Wald chi 62 = 30.364; p = 0.001). Also, a significant difference was found regarding how floods affect the water quality in your community (Wald chi 2 = 1.496; p = 0.030). The subjective perception of flood impacts on households has been reported to be aligned with observed damage to physical structures, underscoring the direct influence of floods on various household elements. The study also emphasises the costly nature of flood recovery and the potential strain on household resources due to flooding. Respondents indicated floods adversely affect vegetation, soil stability, and ecological dynamics. he study also, reveals that while some residents affected by flooding reach out to their municipalities for support, many do not seek or receive financial assistance.Discussion The study concludes that floods have a considerable socioeconomic impact on households and communities, particularly regarding repair costs for flood-related damages. In addition, the study concludes that floods have significant implications for drinking water quality in the community, with statistical evidence supporting the claim that floods contribute to water quality degradation. The findings of flood preparedness suggest a clear gap in early warning dissemination and evacuation planning tailored to the study community's needs. The findings of this study underscore the urgent need for comprehensive and sustainable flood mitigation strategies in vulnerable communities like Bronville and Hani-park.

Soil microbes and enzymes mediate soil carbon-climate feedback, and their responses to increasing temperature partly affect soil carbon stability subjected to the effects of climate change. We performed a 50-month incubation experiment to determine the effect of long-term warming on soil microbes and enzymes involved in carbon cycling along permafrost peatland profile (0-150 cm) and investigated their response to water flooding in the active soil layer. Soil bacteria, fungi, and most enzymes were observed to be sensitive to changes in temperature and water in the permafrost peatland. Bacterial and fungal abundance decreased in the active layer soil but increased in the deepest permafrost layer under warming. The highest decrease in the ratio of soil bacteria to fungi was observed in the deepest permafrost layer under warming. These results indicated that long-term warming promotes recalcitrant carbon loss in permafrost because fungi are more efficient in decomposing high-molecular-weight compounds. Soil microbial catabolic activity measured using Biolog Ecoplates indicated a greater degree of average well color development at 15 degrees C than at 5 degrees C. The highest levels of microbial catabolic activity, functional diversity, and carbon substrate utilization were found in the permafrost boundary layer (60-80 cm). Soil polyphenol oxidase that degrades recalcitrant carbon was more sensitive to increases in temperature than 13-glucosidase, N-acetyl-13-glucosaminidase, and acid phosphatase, which degrade labile carbon. Increasing temperature and water flooding exerted a synergistic effect on the bacterial and fungal abundance and 13-glucosidase, acid phosphatase, and RubisCO activity in the topsoil. Structural equation modeling analysis indicated that soil enzyme activity significantly correlated with ratio of soil bacteria to fungi and microbial catabolic activity. Our results provide valuable insights into the linkage response of soil microorganisms, enzymes to climate change and their feedback to permafrost carbon loss.
