Abstract
Bangladesh has experienced a number of severe natural disasters. Most recently, tropical storms Aila, Sidr and Mohaseen have affected the Kuakata coastal belt. These natural disasters have had substantial negative impacts on natural resources. Development of coping strategies for the protection of natural resources across this belt is significantly important. The present research is focused on the effects of tropical storms on crops, humans, fish, livestock and infrastructure. There were 99 fatalities recorded during the Sidr and Aila natural disasters. These disasters impacted 910.94 ha (Sidr) and 973.69 ha (Aila) of cropland. The total number of affected livestock and fishes such as, 18,200 fish ponds, 1209 cattle, 3324 goats, 6888 chickens, 1716 ducks, 103 buffalo and 144 sheep. After tropical cyclones of Sidr, Aila, Heavy rainstorms and Mohaseen 12,970, 17,703, 10,050 and 2500 households respectively reported some form of damage. Cattle, goat, chicken and buffalo were found more injured than other livestock due to the natural disasters of Sidr. Temperature and wind speed were both found to be statistically significant (p ≤ 0.05) with humidity. Climatic parameters trend has been increased significantly since 1979. Regular monitoring of climatic variables, preparedness activities, and coping strategies would be significantly important for this coastal communities.
Highlights
Bangladesh is located in a region prone to natural disasters [1]
Human The Kuakata coastal belt of Patuakhali was struck by tropical storms Sidr, Aila, and Mohaseen, which originated in the Bay of Bengal in 2007, 2009, and 2013
The effects of tropical cyclones on crops, humans, fish, livestock and households are devastating in the coastal belt
Summary
Bangladesh is located in a region prone to natural disasters [1]. On average, Bangladesh experiences a natural disaster yearly [2]. Natural disasters frequently occur across the coastal belt [3]. Communities in the coastal belt are at risk [4] This region covers approximately 47,201 square km, encompassing 19 districts [5]. Cyclones, storm surges, riverbank erosion and landslides are recurrent natural disasters [6]. Over the last two centuries Bangladesh has been struck by at least 70 storms that resulted in severe damage. The impact of these historic storms was significant, and made international headlines [10]. Sidr and Aila had the greatest impact on the coastal region of Bangladesh [10]
