AID-COMILLA implements a number of project on Ecologically Based Rodent Management training project, research, study, video documentary etc with funding support from DFID/IRRI/PERTTA, NRI, UNDO, Netherlands Organization of Scientific Research etc. in Comilla, Rangamati, Bandarbon, Khagrachori, Kustia, Netrokona, Satkhira & Bogra in collaboration with IRRI, BARI, University of Greenwich-UK, WAGENINGEN-UR Netherlands University of Dhaka (for PhD student) and Modern Rice Milling Unit-Comilla

Agricultural Impact: Rodent infestations in Bangladesh pose a significant threat to agricultural production. Studies have documented that rodents are a persistent problem in rice and wheat fields, causing substantial crop losses. For instance, research indicates that while only 0.5% of wheat seedlings may be damaged by rodents, losses in mature wheat can reach 12.1%, equating to nearly 77,000 tons of grain lost in some cases (ResearchGate, 2015).

Public Health Risks:Beyond agricultural damage, rodents also present serious public health concerns. Studies conducted in Comilla, Bangladesh, found that 13.1% of captured rodents carried Leptospira bacteria, the causative agent of leptospirosis, which can be dangerous to humans (PMC, 2019).

Environmental and Ecological Impact:Rodent populations also influence ecological balance. Periodic rodent outbreaks in relation to bamboo flowering cycles have been observed, where the sudden surge in rodent numbers can threaten crops and disrupt local ecosystems (BanglaJOL, 2020).

Management Strategies:Several strategies have been implemented to control rodent populations. Community-based rodent management programs in areas like Comilla have shown success by involving local communities. Traditional trapping methods and the use of natural predators are also common strategies for controlling rodent populations (Academia, 2013).

Overall, the rodent problem in Bangladesh is a multifaceted challenge affecting agriculture, public health, and the environment. Effective research and integrated management strategies are crucial to mitigating these impacts.
