Farmers’ perceptions and management of risk in rice-based farming systems of south-west coastal 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.

Trees And Shrubs

Leafing, flowering and fruiting of the 24 most representative species of trees and shrubs in Sudanian savannas and fallows near Bondoukuy (Burkina Faso) were studied for 2 y (May 1992 to June 1994). The period of defoliation was generally brief, and leaf flushing, flowering and fruiting occurred mostly in the dry season. The phenological behaviour varied nonetheless across species and individuals. A classification taking into account synchrony/asynchrony and duration in foliation, flowering, fruit ripening and seed dispersal phases allowed comparison of species' phenological plasticity. Species were distributed along a scale of increasing plasticity, from trees to shrubs. Along this scale, species of the Leguminosae appeared to be separated from those of the Combretaceae, the latter being generally considered as characterising fallow farming systems. These results provide new evidence about the effect of phylogenetic constraints on the phenological behaviour of the woody species of the Sudanian savannas.RÉSUMÉ. La feuillaison, la floraison et la fructification des 24 espèces d'arbres et d'arbustes les plus représentatives des jachères et savanes soudaniennes de la région de Bondoukuy (Burkina Faso), ont été étudiées pendant 2 ans (mai 1992 à juin 1994). La défeuillaison est généralement brève et l'émergence des feuilles, la floraison et la fructification se produisent principalement pendant la saison sèche. Les comportements phénologiques varient cependant entre les individus et entre les espèces. Une classification prenant en compte le degré de synchronisme ainsi que la durée de la feuillaison, de la floraison, de la maturation des fruits et de la dispersion des graines a permis de comparer la plasticité phénologique des espèces. Celles-ci sont distribuées selon un gradient de plasticité croissante des arbres aux arbustes. Sur ce gradient les Légumineuses se dissocient des Combrétacées, espèces qui sont par ailleurs généralement considérées comme caractéristiques des jachères. Ces résultats sont une nouvelle illustration de l'effet des contraintes phylogénétiques sur le comportement phénologique des espèces ligneuses des savanes soudaniennes.
