Reducing the natural disaster impacts by using an appropriate water testing technology

Do negative shocks in origin countries encourage or inhibit international migration? What roles do networks play in modifying out-migration responses? The answers to these questions are not theoretically obvious, and past empirical findings are equivocal. We examine the impact of hurricanes on a quarter century of international migration to the United States. Hurricanes increase migration to the United States, with the effect’s magnitude increasing in the size of prior migrant stocks. We provide new insights into how networks facilitate legal, permanent US immigration in response to origin country shocks, a matter of growing importance as climate change increases natural disaster impacts.

Testing Technology

Now, water testing in horizontal well is still a worldwide problem, has not yet been mature and reliable technology is widely used in oil fields. Liaohe oilfield test center after three years of scientific research, has made some progress, developed a set of suitable technology for water testing in Liaohe oilfield horizontal wells, and to apply this technology to the water testing in oil wells, a good test results have been achieved.

Natural Disaster Impacts

We survey the growing literature on fat-tailed distributions in environmental economics. We then examine the theoretical and statistical properties of such distributions, focusing especially on when these properties are likely to arise in environmental problems. We find that a number of variables are fat tailed in environmental economics, including the climate sensitivity, natural disaster impacts, spread of infectious diseases, and stated willingness to pay. We argue that different fat-tailed distributions arise from common pathways. Finally, we review the literature on the policy implications of fat-tailed distributions and controversies over their interpretation. We conclude that the literature has made great strides in demonstrating when fat tails matter for optimal environmental policy. Yet, much is less well understood, including how alternative policies affect fat-tailed distributions, the optimal policy in a computational economy with many fat-tailed problems, and how to account for imprecision in empirical tests for fat tails. Expected final online publication date for the Annual Review of Resource Economics, Volume 13 is October 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

History Of

Due to geographical locations, the Southwestern coastal region of Bangladesh is frequently experiencing climate change induced disasters such as cyclones, floods, and tidal surges. However, local communities at this region have a long history of coping with the adverse effects of these disasters. Consequently, this research assessed the social vulnerability towards natural disasters through local peoples’ perception and identified the existing immediate response against natural disasters at Kazirchar village in Muladi Upazila of Barishal district of the coastal region. In this study, a well-structured questionnaire survey, and focus group discussions were conducted to collect primary data. The collected data were processed and analysed to present the existing impacts of natural disasters. Besides, the immediate responses were categorized into different sectors. The study found that, the most prevalent coastal disaster in Kazirchar village was cyclone. About 48% of surveyed respondents opined that high cost of living was the main reason for increasing the vulnerability towards disasters. To adapt with disaster impacts, 58% respondents of this village need to travel long distances to collect drinking water. On the other hand, during flood, 26% people took shelter on government-owned high lands, whereas 40% shifted temporarily to their neighbors who are living in house with a high land elevation. This research concludes that the village has a low prior preparedness against various disasters, less knowledge about disaster, less coordination and poor collaboration between government organization (GOs) and non-governmental organizations (NGOs) regarding disaster risk reduction. It is expected that this study will act as a source of information for taking natural disaster management initiatives and the findings of this study will push the policy makers to develop and implement long term adaptation strategies in coastal areas of Bangladesh particularly in Barishal district.
