Climate Change Requires New Approaches to Disaster Planning and Response 
David J. Hayes, June 2023

To date, most of the climate policy attention has been focused on the need to reduce the greenhouse gases that are causing climate change and, as a corollary, to accelerate the U.S. economy’s transition from fossil fuels to clean energy. Yet climate change also is straining our nation’s emergency response capabilities as traditional climate-infused disasters such as hurricanes and floods become more frequent and destructive. At the same time, the emergency response community faces new challenges as slower-to-develop climate impacts like drought, heat, and wildfire increasingly are hitting an acute tipping points and becoming life- and livelihood-threatening disasters. Read the full paper (PDF).

Reach, Choice, and Transparency: Governing the Internet in the 21st Century
Steve Johnson, May 2023

As inventions go, the Internet stacks up with the best of them: the lightbulb, the automobile, even fire. In its first thirty years, the Internet’s worldwide adoption and breadth of application has exceeded any other technological advance in history. It expands our reach by bringing people, experiences, and things to us with the click of a mouse. It connects us to an increasing number of gadgets, from smartphones to voice kiosks and soon self-driving vehicles that will no doubt converse with us while we commute, happily oblivious to the traffic around us. We revel in our newfound agility and versatility. Importantly, our precious network kept us sane during a worldwide pandemic and enabled the world to work remotely while most of its population was frozen at home. For resilience against catastrophes alone, the Internet has become indispensable. Read the full paper (PDF).

Combatting Forced Labor in Global Supply Chains
Sarah Bishop, Tom Plotkin and Emanuel Ghebregergis, January, 2023

This paper outlines several recommendations for enhancing the effectiveness of U.S. Government efforts to counter forced labor in global supply chains. First, CBP should enhance the transparency of its forced labor investigative and enforcement activities to better enable the private sector to direct resources to due diligence and remediation. Second, CBP should develop a voluntary disclosure regime with meaningful incentives for importers to report potential issues in their supply chains and undertake proactive corrective action. Finally, the U.S. Government should establish channels for regular communication and information-sharing with foreign governments concerning forced labor enforcement efforts. These recommendations are geared to promote the development of a cross-border, public-private regulatory and enforcement framework within which companies can build more ethical and resilient supply chainsRead the full paper (PDF).

Dismantling Migrant Smuggling Networks in the Americas
Guadalupe Correa-Cabrera, June 27, 2022

The journey to the United States of economic migrants and asylum seekers from developing countries or countries at war is invariably perilous. At the same time, current migration trends
and organized mass irregular migrations pose substantial homeland security risks. This paper proposes the dismantling of migrant smuggling networks through intelligence and targeted actions as important elements both of border security and enforcement and humanitarian migration management. In addition to these policies, the U.S. government should collaborate closely with other governments to cooperatively redesign asylum systems. Read the full paper (PDF).

Toward an Integrated North American Emergency Response System
Juliette Kayyem, June 23, 2022

To meet these challenges, North America must progress beyond the historic approach to cross-border emergency management, which has consisted primarily of sharing information, to a more systemic and operational cooperation. Establishing a North American approach is a key component to more comprehensive and effective emergency management structured to meet current and emerging threats. This paper briefly examines the history of emergency response coordination among the United States, Mexico, and Canada, highlighting some of the major bilateral, regional and non-governmental agreements. It analyzes the challenges in emergency response and the resulting shortfalls of existing agreements, as well as considering lessons from COVID-19 pandemic. These historic and current deficiencies support the creation of a more robust tri-lateral agreement to deal with the pressing nature of evolving emergency response threats in the future. The paper concludes with recommendations on how to adapt the current emergency response systems to function as a North American Emergency Response Compact. Read the full paper (PDF).

Toward a Better Immigration System
Doris Meissner and Ruth Ellen Wasem, April 11, 2022

This paper examines questions of structure—as compared with leadership and policy—and proposes changes that would enable more effective and humane implementation of the nation’s immigration laws. It identifies four key organizational areas of concern—mission, institutional structures, funding priorities, and institutional culture—essential to the vitality and governance of the U.S. immigration system. We argue that immigration is a system that spans both intra-DHS and interagency organizational entities and processes, and that it must operate as a system to successfully carry out its duties. Managing immigration as a system calls for coordinated operational capabilities, decision-making structures, and resource allocations. The paper provides recommendations that can be accomplished within the current authority of the secretary of homeland security and the executive branch. In addition, it closes with select proposals for a longer-term change agenda that would require legislation. Read the full paper (PDF).

Integration of Effort
Sean Atkins and Chappell Lawson, September 02, 2021

This paper proposes that the U.S. Department of Homeland Security (DHS) take the lead in supplementing the traditional “criminal justice” approach to countering transnational crime with strategies that aim to disrupt it and insulate Americans from its harmful effects. We contend the “Disruption Model” outlined here,* if broadly implemented, could significantly complement the current conventional approach, and produce materially improved results in managing the challenges of transnational crime and protecting the homeland from its ravages. Read the full paper (PDF).

Disrupting Transnational Criminal Activity: A Law Enforcement Strategy for Homeland Security
Alan Bersin and Chappell Lawson, May 21, 2021

Because threats to critical infrastructure present a broad danger to society, there is a significant public interest in securing their continuity of operations against cyberattacks. However, because most critical infrastructure is owned by private firms, the government must engage with industry in order to secure them. Unfortunately, the current strategy of engagement is flawed, and the recommendations of the recent Cyber Solarium commission—though valuable—will not solve the problem. A new policy must deliver true integration of effort between the federal government and the relatively small number of systemically important firms. The specific form of this partnership must be tailored to the idiosyncrasies of critical infrastructure sectors. Read the full paper (PDF).

Improving Big Data Integration and Building a Data Culture for U.S. Border Security
Stephen Coulthart and Ryan Riccucci, March 25, 2021

Significant barriers remain for U.S. Customs and Border Protection (CBP) to leverage big data, such as information sharing barriers between operational components as well as safeguarding data from breaches. These barriers are caused by a variety of factors. Like much of the U.S. government, CBP has struggled to develop a data culture receptive to changes brought on by the information technology revolution and has significant issues with its data governance standards, technology acquisition, and human capital development processes. This article explores these issues and offers recommendations to address these and other barriers to unlock the potential of big data for U.S. border security. Read the full paper (PDF).

Lessons Learned: Why the United States Needs a Counter-Pandemic Border Strategy
Robert Bonner and Gillian Horton, September 28, 2020

Because there is an important role for improved, robust border screening against pandemics, we propose a Counter-Pandemic Border Strategy (CPBS) that draws on successful strategies put in place at foreign and U.S. ports of entry in the wake of 9/11, the last time the U.S. government reacted to a truly devastating threat at its borders. Although no single measure can eliminate threats such as terrorism or a pandemic, there are many countermeasures that can be taken, and given what is at stake, there is every reason to put the eight core elements of the CPBS in place. Based on the behavior of COVID-19, as well as new viral threats that are most likely to generate future pandemics, a robust border strategy can play a key role in “flattening the curve”: reducing both lives lost and damage to the U.S. and global economies. Once the United States adopts the CPBS, it should be internationalized through a multinational “SAFE Framework to Counter Pandemics. Read the full paper (PDF).

COVID-19 and the Preexisting Weaknesses and Tensions Within Our Emergency Management Regime
Timothy Perry, July 06, 2020

This article identifies and analyzes several of those weaknesses and tensions. Overall, it concludes that while emergencies may be “locally executed, state managed, and federally supported,”1 the federal government must play a central and catalytic role in harmonizing national policy across the federalist system, and ensuring that states cooperate rather than compete with one another. The article proposes policy changes that would improve the United States’ approach to all threats and hazards while better integrating emergency management into the larger homeland security enterprise. Read the full paper (PDF).

Closing Critical Gaps that Hinder Homeland Security Technology Innovation
Nate Bruggeman and Ben Rohrbaugh, April 23, 2020

Effectively countering these threats, including by developing and supporting private sector-generated new technological solutions, is a core government responsibility. DHS is the U.S. government’s primary civilian public safety agency and the main source of government funding for nonmilitary development of public safety technologies. Unfortunately, DHS has a poor record of developing new technological solutions to advance its mission and address emerging threats. This article assesses the current situation, identifies lines of research that are urgently needed, and makes recommendations on how DHS can more effectively partner with industry and how new technologies can be quickly seeded. Read the full paper (PDF).

Beyond CVE: Evolving U.S. Countering Violent Extremism Policy to Prevent the Growing Threat of Domestic Terrorism
Alexander Guittard, December 01, 2019

U.S. counterterrorism agencies lack the authorities, funding, and political direction to meet the evolving terrorist threat to the United States. Efforts to expand the counterterrorism toolkit to include prevention of all types of terrorism, known under the Bush and Obama Administrations as “countering violent extremism,” or CVE, and under Trump as “terrorism prevention,” have struggled to take hold and the programs have been underfunded and politically unpopular. These efforts have also suffered from the perception that they were biased towards stopping al-Qaeda and ISIS-inspired terrorism and have ignored the threat posed by “right-wing” terrorists. The United States must accept that counterterrorism should evolve beyond relying on law enforcement and intelligence alone to prevent the growing threat of domestic terrorism. This evolution should include developing a bipartisan consensus for addressing all forms of terrorism; funding the types of CVE programs we deliver overseas at home; and updating our terrorism laws to incorporate preventative and restorative approaches that build on the best practices and lessons learned from tackling other forms of crime and targeted violence, such as hate crimes and gang violence. Read the full paper (PDF).

The City-Sized Hole in U.S. GPS Planning
Steven Polunsky, November 21, 2019

Our society has become highly dependent on constant, real-time information about position, navigation, and timing. We typically access this information through cell phones or other devices that receive global positioning system (GPS) signals. Cities are particularly vulnerable to GPS failures and will become more so as Smart City initiatives produce results. Yet, we are missing opportunities to protect localities from potential disaster. This paper recommends efforts at all levels of government that could improve local government resilience, coordinate efforts, involve the private sector, and integrate these initiatives with federal planning for the future. Read the full paper (PDF).

Visa Overstays Play Outsize Role in Unauthorized Migration
Blas Nunez-Neto, September 24, 2019

On April 22, 2019, President Trump signed a Presidential Memorandum directing the Secretaries of State and Homeland Security “to find effective ways to combat the rampant number of overstays.” The White House fact sheet released with this announcement notes that twenty countries have visa overstay rates above 10 percent, and that one action being considered could be to limit the issuance of visas to countries with high rates of visa overstays. This paper will tackle the following questions: How big is the visa overstay problem? How does it compare to other forms of unauthorized migration? And what policy options are available to policymakers? Read the full paper (PDF).

The New Reality of Migrant Flows at the U.S. Southwest Border
Alan Bersin and Nate Bruggeman, June 26, 2019

The United States Government made remarkable progress from the 1990s through the early 2010s (coupled with changing demographic and economic conditions in Mexico) in improving security and reducing illegal immigration at its border with Mexico. Beginning in 2014, however, the situation changed, and it has deteriorated substantially in the last year. A flood of asylum seekers from the Northern Triangle countries of Central American—Honduras, El Salvador, and Guatemala—have overwhelmed U.S. (and Mexican) border officials. Urgent attention is required to address a mounting crisis, requiring action across numerous policy fronts: from foreign affairs and international assistance through reform of the U.S. immigration system and asylum law to amelioration of the dismal security conditions extant in the Northern Triangle. This all amounts to a positive development: not only does the agreement take President Trump’s threatened tariffs on Mexico off the table (at least for now), these steps have the potential to modestly deter and disrupt the human smuggling networks fueling the current crisis. However, the agreement is not a comprehensive and permanent solution. It remains to be seen how the agreement is implemented, including whether Mexico has the capacity and infrastructure to deport tens of thousands of migrants let alone to care properly for an increase in Central Americans waiting in Mexico. Consistent with the original analysis of this paper and accompanying recommendations, the situation still requires urgent attention and a concerted response from the U.S. Congress and the Executive Branch. Read the full paper (PDF).

Reducing Transaction Costs at North America’s Borders
Nate Bruggeman and Ben Rohrbaugh, March 20, 2018

The North American market is a significant driver of U.S. economic activity and competitiveness. Mexico and Canada are the United States’ two biggest export markets, making up over a third of overall U.S. exports valued at more than $580 billion. Imports from both countries contain far higher proportions of American content than goods that are imported from Asia or Europe. Nonetheless, and even recognizing the new era of North American trade created by the North American Free Trade Agreement, there are still significant logistical constraints to commercial flows within North America, with the result that the United States, Mexico, and Canada are effectively leaving money on the table in terms of competitiveness and job growth. And many of these constraints are tied to the efficiency of the countries’ ports of entry. Read the full paper (PDF).
