The five-day symposium that concluded at Hotel Sonargaon in the capital yesterday also emphasised the need for stimulating multi-disciplinary research on the burning issue and identifying effective mitigation and adaptation options, including carbon sequestration in different ecosystems.
The programme was jointly sponsored by
Prof Rattan Lal, director of Carbon Management and Sequestration Centre of Ohio State University, presented the Dhaka Declaration. Experts at the programme observed that climate change will increase temperature, decrease availability of fresh water, contribute to the rise in sea level, glacial melting in the Himalayas, increased frequency and intensity of extreme events, and shifting of cropping zones in South Asia affecting agriculture and food sector, economy, societies and environment.
Prof Lal said, "The serious problems of soil degradation and desertification are likely to be exacerbated by climate change through accelerated erosion, fertility depletion, salinisation and acidification and that subsistence agriculture, characterised by low productivity and extractive farming, is extremely vulnerable to such climatic change."…
