In the fertile, river-woven landscapes of Bangladesh, agriculture remains the lifeblood of the nation, employing over 41% of the population and contributing nearly 14% to the GDP. Yet, this vital sector faces a confluence of challenges: climate change-induced weather unpredictability, shrinking arable land, and labor shortages due to urban migration. Amid these pressures, a technological transformation is taking root—drone-assisted smart agriculture.
Once a futuristic notion, drone technology is now a tangible tool reshaping farming practices across Bangladesh. These unmanned aerial vehicles (UAVs), equipped with high-resolution cameras, infrared sensors, GPS modules, and machine learning algorithms, are revolutionizing how farmers approach their work. Drones are being used for mapping farmlands, monitoring crop health, identifying pest outbreaks, assessing post-disaster damage, and even spraying fertilizers and pesticides with precision. This shift is not merely about efficiency; it represents an evolutionary leap in agricultural practices.
The real-time, data-driven insights provided by drones are at the heart of this transformation. Equipped with multispectral sensors, drones can analyze soil moisture levels, detect plant diseases before they become visible to the naked eye, and assess nutrient deficiencies with remarkable accuracy. This capability allows for more precise application of fertilizers and pesticides, reducing costs and environmental impact while boosting yields through timely interventions. Traditional methods of field scouting are rapidly becoming obsolete, replaced by technology that offers speed and precision.
Institutional support has played a significant role in this technological pivot. In 2024, the Department of Agricultural Extension (DAE), in collaboration with the Asian Development Bank (ADB), launched pilot initiatives integrating drones and satellite imaging into routine field assessments. Over 300 agricultural extension officers across various regions received training in remote sensing technologies, learning to interpret aerial imagery for drought stress, pest patterns, and flood-induced crop losses. The World Bank has also been instrumental in this shift. Under its $578 million Climate-Smart Agriculture Investment Plan, launched in 2023, more than 127,500 Bangladeshi farmers have adopted smart technologies, including UAVs. Early results are promising, with participating farmers reporting yield improvements ranging from 15% to 60% per hectare, depending on the crop and region. In a country where arable land per capita is shrinking and climate volatility is increasing, such gains are not just desirable—they are essential.
The government is taking concrete steps to facilitate broader adoption of drone technology. The Ministry of Agriculture is working with the Civil Aviation Authority of Bangladesh (CAAB) to develop a regulatory framework for drone usage in the agricultural sector. This includes licensing provisions, airspace management, data governance, and user training. While these regulations are still in their early stages, their formulation is crucial for building trust and ensuring safe, scalable operations.
Despite the progress, challenges remain. The cost of high-end agricultural drones, which can range from Tk 300,000 to 500,000, is a significant barrier for smallholder farmers, who make up over 80% of Bangladesh’s farming community. To address this, cooperatives and farmer producer groups (FPGs) are being encouraged to jointly own and operate drones. Private sector startups like AgriBotX and iFarmer are also offering drone services on a per-acre rental basis, reducing entry barriers. Technical know-how is another hurdle, as the operational sophistication of drones demands trained personnel. Organizations like Solidaridad Network and BRAC have initiated community-based drone literacy programs in rural areas, training young agri-entrepreneurs in drone operations, maintenance, and data interpretation.
The academic and research community is also embracing this shift. Universities like Bangladesh Agricultural University (BAU) and institutions like the Bangladesh Agricultural Research Council (BARC) are incorporating drone technology into their research and extension curricula. Collaborative research efforts are underway to refine drone-assisted pest forecasting models and integrate UAV data into national crop insurance schemes, a crucial step in risk mitigation.
Artificial intelligence (AI) is further enhancing the capabilities of drones. The Smart Agro Development Technology project, developed by a team of AI researchers and agronomists, exemplifies this synergy. Using neural network-based classifiers trained on thousands of annotated crop images, SMARD-enabled drones can identify over 30 different crop diseases with an accuracy exceeding 92%. Once a disease is detected, the system recommends treatment protocols and nearest input sources via an integrated mobile app. This intelligent feedback loop minimizes crop loss, maximizes productivity, and empowers farmers with actionable intelligence.
The benefits of drones extend beyond agronomy to economics and the environment. By enabling precise, need-based application of agrochemicals, drones reduce the ecological footprint of farming. Less pesticide runoff into water bodies, fewer emissions from mechanized field equipment
