The Sunamganj district is covered by major Haor systems in the north-eastern region of Bangladesh. Flash flood is the most commonly occurring water related disaster in the Haor areas. During the flash flood it is very common that people lost their primary agricultural productions which are the only source of their livelihood. The present study focuses on the effects of 2017 early flash flooding on rice and fish production of Sunamganj Haor areas. The flood caused enormous damage to agriculture such as rice especially Boro rice and fish production on which the Haor dwellers rely upon for their livelihood. The total affected land of Boro rice cultivation in Haors of Sunamganj was 149,224 hectare and the total amount of damaged rice was 393,855 metric ton (MT). The total number of affected farmers was 315,084. The early flash flood also affects the quality of Haor water which caused the death of fishes. The total amount of damaged fish was 49.75 MT and the loss was 158.70 lakh taka. The total number of affected fishermen was 44,445. This findings could be very useful for the environmental scientists to predict the probable future effects on agricultural production due to early flash flood events in Sunamganj Haors areas.

Bangladesh is a low laying country where disaster events are common phenomena almost every year. Same as coastal areas of Bangladesh, the northern areas are now suffering huge events of floods, droughts and riverbank erosion. The main purpose of this study is to determine the practice of disaster coping strategies by the people in the study areas. The study was carried out at Rajibpur sub-district under Kurigram district, Saghatta sub-district under Gaibandha district, Gangachara sub-district under Rangpur district, Aditmari sub-district under Lalmonirhat district and Dimla sub-district under Nilphamari district. Data were collected from a sample of 300 respondents from 5 subdistricts by using interview schedules 12 January 2017 to 19 March 2018. About 80% respondents are dependent on the TV or Radio news for pre-disaster warning and forecasting as well as more than this population loses their property above BDT 50000 in every year due to disaster damage. During flood, the respondents maintain some scoping materials like raising plinth, making scaffold, using moveable cooking materials, taking loan from the Mahajan and sold their non-productive assets. Most of the respondents from various study area follow these kinds of measures and about 63.33% respondents use bamboo or wood for their cooking purpose during flood. About 40% respondents from these study areas are suffered of shelter due to riverbank erosion and they migrate here and there for better life. More than two third of the respondents have no opportunity to get any kind of help or relief from the GOs and NGOs. They are now depending on their own coping strategies. They badly need a new coping strategy for reducing the damage of flood or riverbank erosion. Disaster forecasting, early warning system and community-based flood management can save many lives and properties. For effective disaster management strategies, it could be applied early warning systems and adequate training as pre-disaster strategy and availability of relief and other inputs at acceptable price and loan with flexible conditions as post-disaster strategy.

A field experiment was carried out during the Boro season 2013 to find out the effects of water management practices on rice yield performance and water productivity index at Old Brahmaputra flood plain paddy land, Muktagacha, Mymensingh. The experiment was laid out in randomized complete block design (RCBD) with six (6) irrigation treatments. Two treatments, T1 and T3 were kept under continuous standing water levels (10 cm and 5 cm respectively) while in treatment T5 irrigation water was supplied for 1st 3 weeks then followed mid season drain out and re-flooded at flowering stage. Three alternate wetting and drying irrigation treatments, T2, T4 and T6 were selected in which irrigation water was applied when water level dropped 20cm, 10cm and 15cm below ground level, respectively. All the irrigation treatments significantly affected the rice yield and yield contributing parameters. The study revealed that the highest grain yield (5950 kg ha-1) was found in treatment T5 which was identical with AWDI treatment T4 (5820 kg ha-1) followed by AWDI treatment T6 (5460 kg ha-1). On the contrary, rice yield of 3350 kg ha-1, 4470 kg ha-1 and 4810 kg ha-1 were found in the treatment T1, T2 and T3, respectively. It was found that AWDI treatment T2 showed maximum water savings (15.1%) followed by T6 (11.3%), T4 (7.59%) and T5 (3.8%), however rice yield in the treatment T2 (4470 kg ha-1) was significantly lower compared to T6, T4 and T5 treatment. Therefore, it may be inferred that treatment T4 (AWDI; irrigation when water level fell 10 cm from ground level), T5 (Irrigation for 1st 3 weeks, then mid-season drain out and re-flooding at flowering) and T6 (AWDI; irrigation when water level fell 15cm from ground level) would be the feasible choice for the water savings, higher rice yield as well as maximum water productivity index (0.478, 0.472 and 0.467, respectively) for sustaining rice farming during the dry Boro season in Bangladesh.J.
