The ecological tradeoffs of desalination in land-constrained countries seeking to mitigate climate change

| Feb. 18, 2022

The global demand for desalinated water is increasing at a remarkable rate. In a future with increasing demand for water and low-carbon electricity, an interesting ecological dilemma emerges. In a decarbonized world, providing desalinated water for domestic use and aquatic ecological restoration could increasingly come at the expense of open space lost to renewables such as solar photovoltaics (PV) and wind turbines. In this article we examine the environmental tradeoffs of providing freshwater from desalination under a solar photovoltaic-based decarbonization strategy, using Israel as an example.

Multi-objective Optimization of Energy and Greenhouse Gas Emissions in Water Pumping and Treatment

| 2020

A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

Lines, Flows and Transnational Crime: Toward a Revised Approach to Countering the Underworld of Globalization

| Dec. 16, 2019

In this article, we develop a new framework for combating transnational criminal activity. We argue that global illicit flows, perpetrated by organized crime, in the interstices of lawful trade and travel, embody a critical and debilitating non-state security threat in today’s world, one that the Westphalian international system of sovereign states remains ill-equipped to confront. Accordingly, we seek to generate a wider discussion in the field regarding a revised approach to this threat that is situated within a global framework of collaborative law enforcement which incorporates, in appropriate fashion, certain military and counter-terrorist strategies.

The propositions we advance in support of a revised approach to countering transnational crime and its globalized web-enabled criminals include: (a) terrorism is one species of transnational crime; (b) the criminal justice model of arrest, prosecution, conviction and incarceration is a partial and insufficient response to transnational crime; (c) national security and law enforcement functions should be viewed analytically as a “public security” continuum rather than disciplines separated by bright lines; (d) countering transnational criminal organizations effectively may require development of a hybrid law enforcement/military capacity and new strategic and tactical doctrines, including safeguards against abuse, to govern its deployment; (e) joint border management within nations and between them, coordinated with the private sector, is required and inter-agency cooperation and multilateral institutions must be strengthened in accordance with new international norms and (f) North America, a region construed as extending from Colombia to the Arctic and from Bermuda to Hawaii, could develop in the future, together with the European Union, as an initial site for a model pilot of the new approach.

Towards Sustainability in Water-energy Nexus: Ocean Energy for Seawater Desalination

In this article, the authors review the state of the art of ocean energy in desalination. It explores different sources of energy from the ocean that include electricity generation, as well as mechanical force and thermal energy and salinity gradients that can also be directly harnessed for powering the desalination processes. They also examine recent advances in scaling up for commercial deployment and discuss relevant cost, environmental, and social concerns.

Preventing the Next Attack: A Strategy for the War on Terrorism

| Oct. 16, 2017

Today, the terrorist threat looks much different than it did right before 9/11. The U.S. counterterrorism community has dramatically ramped up its intelligence capabilities. Determined to “connect the dots” in the future, the U.S. government created new agencies and instituted a new paradigm for intelligence—share by rule, withhold by exception—and set up a slew of “fusion centers” and joint task forces to foster interagency cooperation. Borders were hardened, cockpit doors reinforced, and watch lists created. In Afghanistan, the United States overthrew the Taliban regime, which was hosting al Qaeda. Today, despite recent Taliban gains, al Qaeda still does not enjoy free rein in the country. In Iraq and Syria, al Qaeda’s offshoot, the Islamic State (or ISIS), is on the run, thanks to the work of a global coalition assembled in 2014 and U.S.-led air strikes and special operations raids. The group’s Iraqi capital of Mosul fell in July, and its Syrian stronghold in Raqqa is almost certain to follow. Owing to the relentless pressure that the United States and its allies have placed on terrorists’ safe havens, the threat of a complex and catastrophic attack emanating from abroad—although not gone—has diminished. At the same time, however, the threat from homegrown and so called lone-wolf terrorism has increased.

Using Inclusive Wealth for Policy Evaluation: Application to Electricity Infrastructure Planning in Oil-Exporting Countries

| 2017

Decision-makers often seek to design policies that support sustainable development. Prospective evaluations of how effectively such policies are likely to meet sustainability goals have nonetheless remained relatively challenging. Evaluating policies against sustainability goals can be facilitated through the inclusive wealth framework, which characterizes development in terms of the value to society of its underlying capital assets, and defines development to be potentially sustainable if that value does not decline over time.

A Few Thoughts on Engineering Peaceful and Inclusive Societies

| November 3, 2016

"The rise of nations such as South Korea, Singapore and China as global economic players illustrated the importance of expanding and deepening human competence. A key starting point in the growth process is recognising that building engineering capabilities offered the best opportunity for technological leapfrogging and catch-up in a variety of industries."

Long Lines and Disasters: The TSA in a Time of Troubles

| May 20, 2016

"The way TSA and certainly security experts like me think about security is that we talk about layered security: That is, what you want is enough layers. None of them are perfect; everyone is willing to admit that. You might secure some doors and not others. But you put enough layers in those access points for violence to become a little bit more difficult."
