This paper examines the association between slow-onset natural hazards and the temporal aspects of human mobility-that is, short-term and long-term internal migration in the context of northwest Bangladesh. The paper contributes to the current understanding on the multiple stressors influencing individual's decisions to migrate from their rural origin, while examining the interplay between factors such as tipping points of migration (identified as drivers of migration), socio-demographic variables, and the contexts of slow-onset natural hazards. The analysis is based on empirical data relating to disadvantaged internal migrants or their household members living in drought-prone and riverine areas. A binary logistic regression model is used to analyse how various factors influence the temporality of migration. Key findings indicate that in the context of the natural hazards studied, financial stress at the household level and lack of economic resources are strongly associated with people's decisions to migrate for the-long or short-term. Based on such findings, the paper argues for diversified policy interventions for different groups of internal migrants in order to address difficulties associated with their mobility to and settlement at new locations.

Abstract:To estimate the recreational value provided by the Foy's Lake annually using the most applicable model for on-site data is the main objective of this study. Adhere to the objective of this study; Individual Travel Cost Method (ITCM) has been applied and Zero Truncated Poisson Regression Model has been found plausible among other models to estimate consumer surplus. Based on the findings of the study, an estimate of the consumer surplus or recreational benefits per trip per visitor can be recommended as BDT 5,875 or US $ 73.44 and counting the consumer surplus per trip per visitor, the annual recreational value (total consumer surplus) provided by the lake is found to be BDT 321 million or US $ 40.2 million.

Aman is a rain-fed crop that is the second-largest rice crop in Bangladesh in general and in particular, in the study area with respect to the volume of production. It also carries significant value in the case of food security as well as livelihoo d options for many farmers. At this backdrop, the study focuses on exploring the relationship between climate change variables (Average Maximum Temperature, Average Minimum Temperature, Total rainfall, Average Relative Humidity) and Yield of Aman in Bogra and Joypurhat districts of Bangladesh. In this case, quantile regression at the median is used to examine climate change and Aman rice interrelations using time series data from 1969 to 2013. The f indings of the study reveal that Average Maximum Temperature and Total Rainfall has a positive impact on the Aman yield production in the study area. Considering the future severe adverse effects of climate change on food security and nutrition, and employment aspects in the study area, the study, therefore, recommends the concerned authorities to strengthen their efforts to develop, and distribute of drought-tolerant HYV of Aman rice among the farmers at an affordable rate. Meanwhile, the farmers should be encouraged to cultivate drought-tolerant and less water-fed crops.

Maize cultivation has been gaining popularly in the rangpur district of Bangladesh in recent years. The study is mainly an attempt to explore the reasons for the growing popularity of maize cultivation in the Gangachara upazila (Sub-district) of Rangpur district. It also examines the future viability of maize cultivation in this area. For data collection, three-stage cluster sampling method has been used to determine the setting of the study selecting 110 farmers who have been involving themselves in maize cultivation for at least ten years, by replacing traditional crops like tobacco and boro rice. Benefit-cost (ratio) analysis is carried out in the study for its purpose and it is found that the cultivation of maize is more profitable than that of boro rice and tobacco. Furthermore, water table data analysis in the study also reveals that the ground water level is depleting in the study area in rabi season and causing groundwater scarcity. Therefore, it would be viable to cultivate maize in the near future at the backdrop of the scarcity of the ground water as maize is less water-intensive crop than other traditional crops grown in this region. KEY WORDS Maize, crop diversification, cost-benefit ratio, water table, groundwater.
