Rural households in Ctg show how they can help climate change mitigation, study finds
Beyond forestry and furniture, renewable energy systems were also shown to have strong emission-reduction potential
A new study has revealed that rural households in Bangladesh's Chattogram district can play a significant role in mitigating climate change through a combination of homegarden planting, sustainable furniture production, and renewable energy use.
The research, led by Md Zeesun-Ul Haque and colleagues, was published in Nature.com. It assessed the climate-mitigation potential of rural families and found that simple household-level actions could substantially reduce carbon emissions while improving livelihoods.
According to the study, homegarden trees in the region—commonly including teak (Tectona grandis), albizia (Albizia lebbeck), and acacia (Acacia auriculiformis)—store an average of 42 megagrams of carbon dioxide (CO₂) per hectare. These trees act as a vital carbon sink in a region vulnerable to the impacts of global warming.

The researchers also found that rural households in the "upper-middle" income category achieve additional benefits through sustainable wood use. On average, each household stores about 2.07 Mg CO₂ per year through trees and another 2.32 Mg CO₂ per year by substituting carbon-intensive materials with wood in furniture production.
Beyond forestry and furniture, renewable energy systems were also shown to have strong emission-reduction potential. Biogas use—derived from kitchen and poultry waste—was found to cut emissions by around 2.43 Mg CO₂ per household per year in upper-middle-income families, compared to 1.87 Mg CO₂ in lower-middle-income households.
The findings suggest that scaling up such small-scale practices—planting multipurpose trees, promoting sustainable wooden products, and introducing home biogas systems—could meaningfully contribute to national and global climate goals.
"Household-level carbon management offers a practical and low-cost path to support Bangladesh's climate commitments while enhancing rural livelihoods," the authors concluded.
The study provides policymakers with data-driven evidence that local actions—rooted in rural life and traditional practices—can collectively make a measurable impact on reducing greenhouse gas emissions.
