impact of climate change in Bangladesh
In the southeast of Bangladesh lies the Chittagong Hill Tracts (CHT), a region once lush with forests and rich in natural resources. Over time, however, a combination of anthropogenic pressures and climate change has disrupted its ecological balance. Weather patterns have become increasingly erratic, with prolonged dry spells followed by sudden heavy rains. As a result, water scarcity has emerged as a pressing challenge: wells and natural streams often dry up during the summer months, leaving rural households without reliable access to drinking water. Agriculture—the primary livelihood source for most communities—has also suffered, as unpredictable rainfall undermines traditional jhum cultivation and reduces crop yields, threatening food security and sustenance.
In response, local communities have drawn upon indigenous knowledge to adapt. Practices such as rainwater harvesting, mixed cropping, and small-scale terracing are being revived to conserve soil fertility and retain moisture during dry periods. Alongside community efforts, NGO projects have stepped in to provide additional support. Initiatives include reforestation programs to stabilise slopes and restore ecosystems, the introduction of drought-resistant crop varieties to secure harvests, and the establishment of community-managed water systems that ensure equitable access to scarce resources.
