Role of Homestead Forests in Adaptation to Climate Change: A Study on Households' Perceptions and Relevant Factors in Bandarban Hill District, Bangladesh

Homestead forests play an important role in climate change adaptation and mitigation. This study investigated homestead forest owners' perceptions on climate change and associated impacts, as well as the role that homestead forests could play to enhance households' climate adaptation in Bandarban hill district of Bangladesh. Methods involved randomly surveying a total of 176 homestead households at three different hill altitudes: low, medium, and high. We also analyzed the meteorological data on local rainfall and temperature for the period of 1990 to 2019. Results showed that most (76-94%) of the homestead forest owners perceived an increasing erratic pattern of annual temperature and rainfall which was supported by the analysis of local meteorological data. Forest owners ' perceptions towards changes in tree phenology, increase in food insecurity, landslides, and pest infestation, and decrease in crop production, soil fertility, and seasonal streamflow were revealed as pieces of evidence of climate change impacts that varied significantly with hill altitudes and associated ecosystems. About 66% to 97% of the housheolds perceived that homestead forests could play a pivotal role in enhancing their capacity to adapt with the changing climate by supplying diverse products, services, and environmental benefits. Understanding and perceptions of the environmental benefits of homestead forests also significantly varied with the type of households ' construction, income, and literacy of the household members. Our results will help policymakers to ensure these small-scale homestead forests are conserved since they could also provide multiple environmental benefits e.g., carbon sequestration in addition to enhancing community climate adaptation.
