I construct a set of dynamic macroeconomic models to analyze the effect of unskilled immigration on wage inequality. The immigrants or their descendants do not remain unskilled – over time they may approach or exceed the general level of educational attainment. In the baseline model, the economy's capital supply is determined endogenously by the savings behavior of infinite-lived dynasties, and I also consider models in which the supply of capital is perfectly elastic, or exogenously determined. I derive a simple formula that determines the time discounted value of the skill premium enjoyed by college-educated workers following a change in the rate of immigration for unskilled workers, or a change in the degree or rate at which unskilled immigrants become skilled. I compare the calculations of the skill premiums to data from the US Current Population Survey to determine the long-run effect of different immigrant groups on wage inequality in the United States.

Sundarban is the largest active delta in the world lying at the estuaries of the Rivers Ganga and Brahmaputra. This region is rich in biodiversity and declared World Heritage Site by UNESCO. This delta region is prone to severe natural disasters as well as man-induced catastrophic events. Gosaba Block which is identified as the study area located in Indian part of the Sundarban delta, in South Twenty Four Parganas district of West Bengal puts forward an ideal portrait for people’s struggle and survival strategies against natural disasters. An attempt has been made in this chapter to study the perception of the main occupational groups on the effects of major natural disasters viz. floods, tidal surges and cyclones in Gosaba Block. An endeavor has also been made to explore local survival strategies which are effective for their sustenance in this vulnerable region. Three-hundred persons from different occupational groups, that is, people engaged in agriculture, fishing, crab collection, tiger prawn seed collection, wood collection and honey collection have been surveyed through a pre-designed questionnaire. Six Focus Group Discussions have been conducted, in which each of the groups comprised six members from a particular occupation. The study has revealed that all the occupational groups perceive threats differently from natural disasters and their perceptions vary according to their levels of exposure to the environment. To cope with the natural disasters, each occupational group has devised distinct survival strategies. For proper management of natural disasters in Sundarban delta region, the perception of people with different livelihoods and their survival strategies should be incorporated.

Changing climate dynamics have resulted in a confluence of disaster events to which Louisiana government leaders and emergency managers have never before had to respond simultaneously: a global pandemic and an “epidemic” of landfalling hurricanes during the 2020 season (eight cones over Louisiana) with challenging, unusual characteristics: (1) two hurricanes passing over the same location within 36 hours, a fujiwhara – Hurricanes Marco and Laura, (2) 150 mile-per-hour winds inadequately forecasted and of an almost unprecedented speed, (3) a difficult to forecast surge magnitude that led to incorrect immediate response, (4) delayed long-term recovery efforts from responders outside of the area because of initial reporting errors regarding surge heights and wind speed, and (5) a storm, Zeta, that passed directly over a densely populated area that would have been hard hit by rain if the storm had slowed. In addition, the number and closeness in dates of storm occurrences led to lengthy coastal high-water levels. To these co-occurring threats forecasters, state and local officials and residents responded with expertise and commitment, adhering to close collaboration, modifying evacuations and undertaking protective measures, all contributing to a low death rate from storms and a modest death rate from COVID. More just outcomes were supported by the general capacity of the responders, commitment to keep the residents informed about both risks and appropriate responses to them and the provision of special services, calculated for the new situation of the pandemic and the storm epidemic, for those without the means to respond adequately to both.

Little attention has been given to the mental and physical health impacts of COVID-19 on the academic public health workforce. Academic public health is an important support mechanism for public health practice, providing expertise and workforce training, conducting research, disseminating evidence-based scientific information to both public health and lay audiences, and serving as a supplementary workforce when additional resources are needed. These roles become more important during a public health emergency, particularly during a prolonged public health crisis like the COVID-19 pandemic. As a result of the COVID-19 response, the roles of academic public health have expanded to include developing and implementing contact tracing, surveillance, testing, and vaccination programs for universities and their surrounding communities, all while continuing to prepare students and support the public health practice workforce in their ongoing efforts. As in other responder groups, this has resulted in significant mental health effects and burnout among public health academicians. The authors suggest important steps that can be taken to improve the resilience of the academic public health workforce and to support their contributions during prolonged public health emergencies.

This chapter highlights ecosystem-based adaptation in coastal Bangladesh aimed at securing climate and disaster-resilient environment for safer life and livelihood for vulnerable communities in the face of changing climate. Development intervention based on the opportunities offered by the nature and adaptation management plan from the perspective of vulnerability analysis can make a substantive difference in enhancing resilience. Engagement of broad-based stakeholders at vertical and horizontal levels in building adaptive capacity can be linked through both at the policy and institutional levels as well as at ecosystem levels for effective results. Innovation in convergence of disaster risk reduction and adaptation through fish, fruit, and forest as a part of livelihood integrated into the coastal afforestation ensure better livelihood in a safer coastal habitats. Such forest-based adaptive livelihood and carbon sequestration help land development that is promising to offset the sea level rise due to higher rate of siltation. Climate resilient habitat is another innovative initiative that protects the households, and their livelihood is protected by eco-engineering structures and green defense to make it safer from cyclone and tidal surge.

Global imbalances and financial crisis discussed in the preceding chapters were not the only contemporary issues that shaped the current and future landscape of the world economy. Since 2004, many countries also felt a significant shock prompted by a surge in the oil price, forcing them to look for the appropriate policy response that would produce least pain and minimum impact on welfare. The fact that oil remains an important source of energy for many countries, developed and developing alike, a price surge can trigger a new round of global conflicts. Indeed, from the hording of grain in Neolithic times to rivalry over resources in the interimperial wars of the 16th–19th centuries that laid the groundwork for World War I, and to modern nations warring over oil, competition and the desire to have a control over the possession of critical sources of vital materials had always been at the center of conflicts from the very beginning of human story. To prop up their industrialization, for a long period of time developed countries had relied on a stable supply of oil, making their political and strategic relations with oil-producing countries so critical, yet fragile and crisis prone. Conflicts and wars over oil were fought among the oil-producing countries as well.¹ Although it was not admitted by the U.S. administration, at least not publicly, the desire to have greater control over oil was also the primary reason for the 2003 U.S. invasion of Iraq.

The southwest coastal region is part of an inactive delta of large Himalayan rivers and is protected from tidal surge by the Sundarbans mangrove forest. This area is the hub of all types of disasters such as cyclones, tidal surges, floods, drought, salinity intrusions, repeated waterlogging, and land subsidence. Cyclonic tidal surges and floods are the more common disasters, and their effects are frequently experienced at the local level. But silent and invisible disasters such as increased salinity, arsenic contamination, and drought affect local livelihoods, people, and environments in this region. The vulnerability of southwest region to increased salinity, arsenic contamination, and drought are the result of a complex interrelationship among biophysical, social, economical, and technological characteristics of the country. Moreover, in the current and foreseeable future, the country is likely to be affected by the biggest, most long-lasting, and global scale but silent disaster: increased salinity, natural arsenic contamination, and drought. Therefore, this region is thought to be the most disaster-prone region in Bangladesh because of natural disasters and highly vulnerable to the effects of climate change.

The immigration conundrum to craft policy that ensures border security and safeguards human rights is grave and complex. Individuals fleeing religious persecution made finding refuge part of our heritage since colonial times. This American tradition has enshrined our values to the world. This essay is limited to summarizing the asylum process and recent events through the summer of 2018 which affect it. Policy changes are ongoing. The asylum process is complicated by illegal immigration. The surge in migrants arriving at and/or crossing the border has led to controversial policies over the years. Unlike those who illegally cross the border and remain unknown to law enforcement, everyone who makes an affirmative asylum claim to a United States Citizenship and Immigration Services (USCIS) officer, or a defensive asylum claim in immigration court, has been thoroughly vetted through identity, criminality, and terrorism background checks. Granting refuge to those fleeing persecution reaffirms the values of a country that is, as Lincoln richly stated, the last best hope of Earth. Comprehensive immigration reform is needed on many immigration issues, two of which are to ensure border security and safeguard the asylum-seeking process.

Before exploring the political implications of the emerging middle class, best to begin by defining the term. The economists who herald the growth of the middle class in the developing world today largely construe the term solely as an income category. This is in stark contrast to Marx, who defined class in terms of a social group's relation to the means of production, and it is in stark contrast to Weber, who defined class in terms of a group's pattern of consumption. But even if economists agree to conceive of the middle class as an income category, they differ on how to define this category – whether in relative or absolute terms.³ Some, like Lester Thurow, define middle class relationally. People are middle class if their income falls between 75% and 125% of the median income in a given society. Others define middle class in absolute terms. In the case of Milanovic and Yitzhaki, the boundaries of the contemporary global middle class are set between the average income levels that currently prevail in Brazil and Italy (threshold and ceiling, respectively).⁴ Still others like Diana Farrell define middle class in terms of relative access to discretionary spending. For Farrell, the middle class is distinguished from the poor in that it does not live “hand to mouth.” Members of the middle class are defined as those who have roughly a third of their income left over for discretionary spending after covering the basic cost of food and shelter.
