“…A range of health impacts related to rising sea levels are likely to occur, with changes in water and soil quality and supply, livelihood security, disease vector ecology, flooding, and saltwater intrusion. 116,117 The health consequences of these effects will depend on various factors, including the options of both in situ and migration adaptation. [118][119][120] These effects could be moderated if countries begin to prepare.…”

“…Models project that, by 2100, SLR alone could displace 13 million residents, with half of those in Florida. Some communities across the country have begun managed retreat programmes in response (Hauer et al, 2020). In the US, climate migrants tend to move towards mid-sized cities like Atlanta, Austin, and Orlando (Hauer et al, 2020).…”

Climate migration and health system preparedness in the United States

Every country will have to prepare for climate change. Despite obvious risks to national security in terms of safety, food, and infrastructure as well as impending economic losses, countries like the United States (US) have declined to pursue meaningful federal action. The human impact of climate changespecifically climate migration and its health implicationshas been largely neglected at a policy level. Yet climate migration is predicted to have tremendous consequences for people in the next 30 years and beyond, and with it comes a host of difficulties political, cultural, economic, and structural. Preparedness will be of great importance to potential migrants and how they adapt to their receiving (host) locations. Health systems are one of the most significant institutions impacting long-term migration and these systems' strengths and weaknesses will determine the integration and well-being of migrants for years to come. A critical analysis of existing literature exposes that there is little current research on health system preparedness as it relates to climate migration, especially in the US. To help address this gap, this paper focuses on how the American health system, already fraught with limitations, can prepare for the expected increase in mostly internal migrants in the face of climate change. Key policy insights. Climate migration in the US will pose huge challenges for health systems because of the American health system's unique, pre-existing weaknesses.. To prepare for climate migration, federal, state, local, tribal, and territorial governments should focus on adopting a universal healthcare policy, shifting primary care tasks away from physicians and towards other qualified and more ubiquitous professionals, and investing in telemedicine, retail clinics, and a national electronic health record system.. A 'health in all policies' approach, which applies a health lens to legislation, needs to be applied in the context of health system strengthening for climate migration since countless environmental determinants of health and infrastructural decisions shape the vulnerability of communities.

“…Therefore, agriculture in southern low-lying areas of Bangladesh is likely to become increasingly difficult to sustain. The land mass of Bangladesh being already quite limited and its population density is one of the highest in the world, continuous land engulfing by rising sea water will only bring grave consequences forcing the coastal people to become climatic refugees [10][11]. A generalized radiation or diffusion model predicted that 0.9 million people will migrate due to sea level rise in Bangladesh by 2050 and 2.1 million by 2100, largely internally, with substantial implications for nutrition, shelter and employment in destination areas [12].…”

Global Warming and Sea Level Rising: Impact on Agriculture and Food Security in Southern Coastal Region of Bangladesh

Climatologically, the entire southern coastal belt of Bangladesh is most vulnerable than the other parts of the country due to its spatial geo-morphological settings. Global warming and sea level rise are already observed and predicted to be occurred more with time. These bring real negative consequences on the agricultural production and food security, and livelihood for the people live in the coastal areas. Therefore, the study was conducted to analyze the effect of global warming and sea level rise on the agriculture and food security in southern coastal areas of Bangladesh. Both primary and secondary sources of information were collected. Stakeholder consultation, direct field visits and interview of climate affected people in the coastal region were carried out for collecting information on land-use and cropping patterns and adaptation measures to be taken to boost crop production against global warming and sea level rise. By the middle and end of the twenty first century, global annual mean temperature is predicted to be increased about 1.5oC and 2.5oC, respectively. These projected warming will lead to about 14, 32 and 88 cm sea level rise by 2030, 2050 and 2100, respectively which would cause inundation of about 8, 10 and 16 percent of total land masses in Bangladesh. Most of the coastal parts and associated islands of Khulna and Barisal divisions and western part of Chattagram division lie within one meter from sea level where incursion of saline water is common. It is predicted that these areas will be inundated and unsuitable for crop production due to upcoming sea level rise. The predominant crop in entire coastal belt is transplanted Aman with sporadic occurrences of Aus rice. The land in Boro rice season either loosely occupied by mungbean, grass pea, cowpea, groundnut, soybean, potato, sweet potato, chili etc or remained fallow until the following monsoon. A systemic analysis of all of the cyclones that originated from the Bay of Bengal since 1961 indicated that most devastating cyclones formation occurred from last quarter of April through May and from middle of October to November just prior to the harvest of Boro and Aman crops, respectively. Therefore, Boro and Aman rice harvests are mostly unpredictable every year posing great threat to the food security of the coastal people. These areas are criss-crossed by innumerable water canals or channels especially in Barisal and Khulna divisions which can be utilized for Boro rice cultivation in dry season despite some levels of salinity. Cultivation of salt-tolerant crop varieties could mitigate such hindrances. Introduction of saline tolerant Boro rice in coastal cropping patterns and/or advancing the harvesting times by a fortnight in both Aman and Boro rice seasons to avert cyclonic havoc not only ensure food security but also turn the entire coastal belt into a food surplus region.
