Trajectories of cropping system intensification under changing environment in south-west coastal Bangladesh

About 1.0 million ha coastal lands in Bangladesh are mono-cropped suffer from varying degree of soil salinity, waterlogging and climate vulnerability. Low yielding, traditional T. Aman rice is grown only in wet season. Growing non-rice crop after late harvested T. Aman rice is not profitable. This study was aimed to introduce high yielding, short duration T. Aman rice varieties for advancing its harvesting time and to make the avenue for timely establishment of dry season crops. Varietal trials were made at Dacope and Amtali under ACIAR funded project during 2016-2018 and compared with local cultivars. Among tested varieties BRRI dhan76 followed by BRRI dhan77 and BRRI dhan54 in Dacope and BRRI dhan77 followed by BRRI dhan76 and BRRI dhan54 in Amtali were preferred for 0.5–1.0 tha−1 yield advantage and 15–25 days earliness compared to traditional varieties. Early harvesting of T. Aman created the avenue of timely establishment of rice and non-rice crops depending on availability of fresh water and thus crop intensification and land productivity was improved. The new cropping system increased annual rice yield and farmers’ profits by 1.5- to 2-folds compared with traditional system without environmental degradation. This technique can be replicated in similar coastal zones of Bangladesh.

Aims: The study investigated the impacts of COVID-19 on livelihood status of coastal Shrimp farmers using farm size, production and income of South-west Bangladesh. Study Design: This study is empirical in its design. Data on socio-economic factors were collected randomly from selected Shrimp farmers. Both open and closed ended questionnaire and directed to the Shrimp farmers of South-west coastal region of Bangladesh. Place and Duration of Study: The present study was carried out at Khulna district (seven selected Shrimp farming locations; viz., Paikgacha, Lasker, Goroikhali, Lata, Kapilmuni, Amadi and Koyra) of Bangladesh for a period of five months during pandemic of COVID-19 (April-August, 2020). Methodology: The key data were collected from face to face interview of 120 respondents. A brief outline about the nature and aim of the study was given to each respondent before the interview was commenced. The information of the respondents were written in the questionnaire immediately after completing the interview. Collected data were tabulated and analyzed using Microsoft Excel (version 2016). Results: Most of the respondents were middle aged (68 %) and living in nuclear families (71 %). Majority of the Shrimp farmers were illiterate (53 %). A greater proportion (66 %) involved in small scale Shrimp farming as a primary occupation followed by moderate (27 %) and large scale (7 %) Shrimp farming. More than half of the respondents earned >20000 BDT (USD$ 1 = 85 BDT) in each month before the pandemic. The production activities were seriously hampered due to unavailability of inputs including aquamedicine, disinfectants, labor crisis, seed and feed, growing the price of production materials and interrupted communication etc. due to the pandemic. However the outbreak of COVID-19 pandemic reduced the production from their Shrimp ghers, drastically curtailed the market price, and consequently greatly compressed their income and livelihoods. Conclusion: The pandemic known as COVID-19 has had a catastrophic impact on human activities, with the Shrimp farming sector being no exception. This study revealed that the socio-economic and income status of the Shrimp farmers was noticeably vulnerable during the COVID-19 pandemic. Thus, large numbers of farmer families were unable to fulfill their minimum needs (food, income, and medical care).

The Future

Aims: The aim of the study was to assess the indicator based climate change vulnerability of south west coastal Bangladesh and its future. Place of Study: Four districts form south west coastal Bangladesh, having a total of 50 upazilas, have been selected as the study area. They are Satkhira, Khulna, Bagerhat, Pirojpur, Barguna and Patuakhali districts. Methodology: This study has been conducted, using multivariate statistical techniques, to assess the vulnerabilities of the coastal region of Bangladesh by considering the IPCC framework of vulnerability studies. A total of 31 indicators have been selected of which 23 are socio-economic and 8 are biophysical which have been retrieved from the secondary sources. Principal Component Analysis (PCA) has been applied to derive unbiased weights of all indicators considering both present (2011) and the future (2050) climate change scenarios. Results: This study has identiﬁed 7 principal components through PCA which has been grouped as PC1 (Demographic Vulnerability), PC2 (Economic Vulnerability), PC3 (Climatic Vulnerability), PC4 (Health Vulnerability), PC5 (Agricultural Vulnerability), PC6 (Infrastructural Vulnerability) and PC7 (Water Vulnerability). For all 7 PCA groups (termed as vulnerability proﬁle), the number of high and medium vulnerable coastal Upazilas will be significantly changed in the future. No of highly vulnerable Upazila will increase from 0 to 1 for PC1, unchanged for PC2, increase from 0 to 1 for PC3, from 32 to 33 for PC4, from 47 to 68 for PC5, decrease from 48 to 46 for PC6, and an increase from 14 to 21 for PC7, respectively. Conclusion: Discrete spatial maps of each profile have been generated to assess the regional variation of all vulnerability proﬁles across the southwest coastal region of Bangladesh. The ﬁndings of this study might be useful for policy makers and planners.

A survey was conducted to determine the effect of climate change on crop production and water quality in 12 villages of Deluty and Garaikhali unions under Paikgacha upazila of Khulna district, Bangladesh. Total of 100 farmers were interviewed using a pre-tested questionnaire. The climatic hazards as reported on the study area are salinity, cyclone, drought, hailstorm, river erosion and waterlogging, of them salinity is the most dominant hazard. Due to salinity the cropping system has undergone changes. Many crops and varieties have been either extinct or their cultivation has come down. Both soil and water are severely affected by salinity. Most of the farmers (90%) use pond water for irrigation and the majority farmers use pond and rain waters for drinking purpose. Results of the present study serves as a good basis for in-depth study to achieve successful crop production in the south west coastal area of Bangladesh.Res. Agric., Livest.
