Use of satellites and pulse doppler rudder |
Flash flood has caused great damage to the farmers of haor(low lying water bodies) areas. Unusual precipitation and water flows from the upstream inundate paddy fields. A large part of the winter crop has yet to be harvested. News paper reports put the damage toll as low as 10000 hectares to as high as 54000 hectares in Sunamganj and Bagerhat. Affected districts include Sunamganj,Moulovibazar,Sylhet,Comilla and Bagerhat.But the official estimate of the damage is much lower (See "Floodwaters swallo haor harvest in Sunamganj, leaving farmers counting losses", by Debashish Debu, Daily Business Standard, April 30,2026,https://www.tbsnews.net/bangladesh/floodwaters-swallow-haor-harvest-sunamganj-leaving-farmers-counting-losses-1425466).
This flash flood is not new to Bangladeshis in the April-June period. Bangladesh is pretty familiar with such flash floods.Recurrence of such calamities lays bare failure in preparation. The damage is not only to crops; hidden losses are also there.
Agricultural inputs like fertilizers, irrigation, labor were employed in the cultivation process. Fertilizers are heavily subsidized. Since winter crops depend on irrigation, subsidized electricity and diesel were also used in the Boro or winter paddy cultivation. Gone are the subsidized inputs with the winter crops.
Many farmers also borrowed heavily from relatives, money lenders and microfinance institutions. The lent money on the submerged crops now becomes bad. The money cannot be recuperated and it will affect credit distribution next year,curtailing the amount of credit for distribution and narrowing the scope of agriculture and nonagricultural activities in the rural area.
The flash flood also pushed many farmer below the poverty line. Govt now has to arrange resources for them to fight the poverty till the next harvest, sacrificing other priority areas. The incidence of urban bound migration is also likely to rise, worsening further the urban poverty.
There are means to contain the damages from flash flood. Pulse Doppler rudder and remote sensing electro optical satellite are some options. Employing Pulse Doppler rudder near mountainous region could give localize early warning,saving lives and crops. Bangladesh depends on foreign satellites for meteorological data. The data could take 24 hours or more time to reach, rendering the meteorological forecast useless. Having our own remote sensing satellites is the solution. Pakistan recently put into orbit three remote sensing satellites. The constellation is designed to “support disaster response, land management, agricultural monitoring, environmental security, and increasingly sophisticated national surveillance requirements"(see "Pakistan Launches PRSC EO3 Satellite From China,Strengthening Strategic ISR,Space Surveillance and National Security Power", Defence Security Asia,April 26,2026, https://defencesecurityasia.com/en/pakistan-prsc-eo3-satellite-launch-china-isr-space-surveillance-strategic-security/). As Bangladesh houses several flood plains and flash flood becomes regular phenomenon, having our own remote sensing electro-optical satellite has become a necessity. Pakistani SUPARCO designed and built the satellites at its Satellite Research and Development Center. In Bangladesh, Space Research and Remote Sensing Organization(SPARRSO ) could set up similar satellite manufacturing facility and spearhead building of remote sensing satellites. Timely data from such satellites will help building correct modeling, leading to accurate forecast and minimize the damage.
It is a pity we spend billions of Taka on roads and embankments meant to be washed away every year, but we never allocate a tiny fraction of those spendings for some homebuilt satellites. The 2024 and 2026 disasters call for immediate use of Pulse Doppler rudder and remote sensing satellites for early preparedness and damage minimization in the event of recurring natural calamities.
