Agriculture is the backbone of rural communities in Bangladesh, where farming employs more than 60% of the population. Farmers have been cultivating their lands using plenty of work, water, and expense. As rice is the staple food of Bangladesh, rice farming has a distinct place among the numerous forms of agriculture, including fish farming, raising livestock, and cultivating crops. Given that rice farming provides food for millions of people, its contribution to reducing the country’s food shortfall cannot be overstated. However, several socioeconomic and environmental issues are working together to undermine this lifeline more and more.

Groundwater depletion: The erosion of vital resources in the northern regions

Although rivers encircle the country, Bangladesh has experienced a consistent decline in groundwater levels over time. There are several reasons for this loss, but two of the most important ones are natural disasters like droughts and floods and the detrimental impacts of climate change on the ecosystem in the area. The highlands of northern Bangladesh, especially the divisions of Rangpur, are where the problem is most noticeable. Water, the most important resource for growing rice, is becoming more difficult to obtain and more expensive, putting farmers in these areas—who are already struggling with resource constraints—at a crossroads.

The promise of direct-seeded rice (DSR) technology

DSR technology is an innovative approach that can potentially transform the rice farming industry. DSR reduces the requirement for fields to be continuously flooded, unlike the transplanting method. It reduces labor and water usage by up to 50%, conserving resources (Marasini et al., 2016). This technical breakthrough offers promise for farmers who are increasingly battling resource depletion and climate change. DSR eliminates the need to transplant seedlings from a nursery and streamlines the process while preserving or increasing the potential yield (Bista, 2018).

The revolutionary farming strategy is benefiting one group of farmers in northern Bangladesh. During the 2024 aus season, 45 farmers, including three women, assembled in the village of Kutipara, which is situated in the Kishoreganj Upazila of the Nilphamari District, to implement DSR. These farmers used DSR on 16 hectares of land with assistance from the International Rice Research Institute (IRRI).

The group used the transplanting method in 2023 dealt with the usual problems of labor shortage and high water use. The launch of DSR started a sea change. Head-to-head rice varietal adaptation experiments were carried out under the IRRI’s auspices to evaluate yield, disease resistance, and environmental adaptability of BRRI dhan-48, BRRI dhan-75, BRRI dhan-82, BRRI dhan-85, BRRI dhan-98 in uniform settings using DSR. According to the experiments, BRRI dhan-98 and BRRI dhan-75 exhibited the best qualities suited for the Nilphamari Region in Rangpur. To demonstrate their performance in broader regions using mechanized DSR, the rice varieties were included in the cluster demonstration during the aus season.

IRRI researchers were instrumental in persuading the farmers to change their rice cultivation practices. The IRRI Team conducted courtyard sessions over several days, showcasing the benefits of DSR with field visits and posters, pictures, and documentary videos. To make the sowing procedure easier, IRRI additionally acquired a power-tiller operated seeder (PTOS) machine and made arrangements for irrigation with the help of Local Service Providers (LSP). The team visited the farmers daily for ten consecutive days, offering informal training sessions and answering their questions.
