This testimonial is written by Professor Dennis S. Tachiki of Tamagawa University in support of two articles written by MM Murshed on topics related to cooperatives and sustainable development in Bangladesh. Professor Tachiki commends Murshed for writing concise yet informative articles targeted towards cooperative members in Bangladesh. One article discusses the importance of prioritizing long-term societal benefits over short-term personal gains for cooperative development. The other raises awareness of sustainable resource use and conservation for future generations in Bangladesh. Professor Tachiki believes Murshed's articles can contribute to Bangladesh's future progress.
