Abstract
Agricultural production is the backbone of the economy of Bangladesh. It
provides livelihoods for millions and ensuring food security, but the
profitability and productivity are increasingly strained by climate-induced
stresses. This study is an effort to assess the impacts of climate change on
agricultural profitability and productivity with focus on major crops, including
rice, wheat, and mustard in Chapai Nawabganj district, Bangladesh. A simple
random sampling is used to collect primary data from 300 farmers in two unions
of Shibganj Upazila. A profit function was used to determine whether the major
crops production was profitable or not and Cobb-Douglas production function
was also applied to assess the factors of these prime crop production in the study
area. The result reveals that the major crops production including rice, wheat,
and mustard are profitable per bigha with the values of 34,086.26 BDT,
17,575.57 BDT, and 26,299.79 BDT respectively in the study area but not
satisfactory according to farmer’s opinion. Labor, pesticides, and transport were
the three most important factors causing rice production while fertilizer and
labor were the contributing factors of wheat and mustard respectively. Besides,
among 300 respondents, the largest proportion (24.67%) reported average
annual financial losses of BDT 20,001–25,000 due to pests, diseases, droughts,
strong winds, or high temperatures. To combat climate change impacts in
Chapai Nawabganj, policies should focus on promoting climate-resilient crops,
efficient water management, soil health improvement, and sustainable
agricultural practices, enhance access to credit, insurance, and market
infrastructure. In addition, invest in farmer training, climate information
systems, and public-private partnerships for adaptive technologies may be way
of improving sustainable agricultural productivity.
