Bangladesh is one of the most vulnerable countries for climate change in agricultural water management. A research had been done to assess climate change effects on irrigation water use of wheat and maize in the northern part of Bangladesh. The twenty nine years of data (1990-2018) were analyzed with Mann-Kendall test as well as Sen’s slope for climate change impact and the responsible weather parameters due to climate change were identified with correlation coefficients. The crop water requirement of wheat in Bogura and Rangpur was declining at the rate of 3.3mm and 2.3mm per decade respectively. Net irrigation water requirement of wheat at both Bogura and Rangpur was inclining at the rate of 1mm and 10mm per decade respectively because the effective rainfall of these regions was decreasing at 5mm and 11mm per decade respectively. The crop water requirement of maize for similar districts was increasing at the rate of 3.2mm and 2.5mm per decade respectively although net irrigation water requirement had statistically non-significance for climate change effect. The weather parameter, which was mainly responsible for climatic change in irrigation water requirement, was increasing temperature. Therefore, wheat cultivation might be coped with climate change in the northern part of Bangladesh rather than maize on the basis of irrigation and water management.

“…Increased grain yield of wheat is primary goal in drought affected areas. The use of drought resistant genotypes with higher yield is an effective approach to reduce harmful effects of drought [74]. In the present studies, significant differences were found for yield per unit area among the indices was used as screening criteria [76].…”

Sustainable wheat production in drought prone areas can be achieved by developing resilient wheat varieties. In the present study, chemical mutagenesis was used to induce mutations in a cultivated wheat variety ‘NN-Gandum-1’. In total, 44 mutants were selected based on their high yield potential for exposing to well-watered (W1) and rainfed (W2) conditions for one season. Then 24 mutants were selected, and were exposed to W1 and W2 regimes. On the basis of least relative reduction in physiological parameters under W2 regime, five mutants were selected for conducting exome capturing assays. In total, 184 SNPs were identified in nine genes (ABC transporter type 1, Aspartic peptidase, Cytochrome P450, transmembrane domain, Heavy metal-associated domain, HMA, NAC domain, NAD (P)-binding domain, S-type anion channel, Ubiquitin-conjugating enzyme E2 and UDP-glucuronosyl/UDP-glucosyltransferase). Maximum number of mutations were observed in chr.2D, which contained mutations in three genes i.e. ABC transporter type 1, NAD (P)-binding domain and UDP-glucuronosyl/UDP-glucosyltransferase which may have a role in conferring drought tolerance. The selected mutants were further tested for studying their biochemical responses under both the regimes for two years. The extent of membrane damage was estimated through malondialdehydeand hydrogen per oxidase and tolerance to drought stress was assessed via antioxidant enzymes in leaves. The selected mutants under drought stress increased the accumulation of proline content, total soluble sugars, total free amino acids, while decreased total chlorophyll content, carotenoids and total soluble protein. Finally, the procedure of narrowing down the number of developed mutants from a large mutation population (>4000) is found useful for exploring the complex trait like drought without compromising yield potential. These mutants can further be explored to understand the genetic circuits of drought tolerance in wheat which will pave the way towards improving livelihood of resource poor farming community mostly relying on cereal food.

“…The Halda River basin in Bangladesh, known for its extensive agricultural importance (Haque et al 2020), experiences substantial discharge during monsoons, which can cause oods in nearby areas and Chittagong City (Raihan et al 2022). Severe land degradation adds to the basin's challenges.…”

The Halda River is a vital perennial river with significant ecosystem service throughout its course. We studied the characteristics of river monsoon flow using the HEC-HMS to determine the flash flood simulation potential of the cascade reservoir model. The curve numbers are optimized here based on SWAT simulation data. The NSE, R2(RMSE), RSE, and PBIAS estimate values agree with the observed discharge values for the calibration and validation periods. However, during the calibration period, the flow model showed a poor match for the baseflow part, which affected the model's efficiency. Using this approach, flash flood studies can potentially simulate flash floods in a relatively ungauged river basin with minimal discharge data and available water level data. Moreover, the computational cost is lower than that of a similar capacity flow model.
