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.

Beyond 2020: Policy Recommendations for the Future of Election Security

| February 2021

The 2020 election presents a paradox. Despite dramatic changes to the election process due to the COVID-19 pandemic and increasingly complex threats since the 2016 election, 2020 is widely regarded as “the most secure [election] in American history.” Operationally, it was also one of the smoothest. State and local election officials overcame unprecedented challenges and scarce resources to administer an election with fewer incidents of cyber compromises, technical failures or long lines than anticipated. After Election Day, recount procedures functioned as designed. Yet, amidst these successes, officials from both parties faced a barrage of mis- and disinformation about the election process that served to undermine confidence in the result.

Though the election security ecosystem survived the triple threat of cybersecurity, physical security, and mis- and disinformation in 2020, this success will prove to be hard to replicate in future election cycles without proper investment and reinforcement.

D3P Helps Safeguard 2020 Elections

| Fall 2020

A number of factors in the fall of 2020 made it easier for agents of disinformation to cast doubt on the legitimacy of the election process and results—before, during, and after election day. Working to thwart them, however, was an army of well-trained election officials. Much of their training was carried out by the Belfer Center’s Defending Digital Democracy Project (D3P).

Center Experts Reflect on 75th Anniversary of Hiroshima Bombing

On August 6, 1945, the United States dropped an atomic bomb on Hiroshima, Japan, launching the nuclear age. On the 75th anniversary of that somber event, Belfer Center experts reflect on the event and its aftermath.

Considerations for Digital Contact Tracing Tools for COVID-19 Mitigation: Recommendations for Stakeholders and Policymakers

Many are looking to digital contact tracing to assist reopening efforts, especially in light of reports that the U.S. could expect as many as 100,000 more deaths due to the virus by this Fall. This report focuses on how the U.S. might consider various proposed solutions.

We believe there are real benefits, challenges, and even potential harms in using digital solutions in the fight against COVID-19, but we must also acknowledge that the promise of any technology and associated systems to assist manual contact tracing efforts is largely hypothetical in the United States. There is not one catch-all answer; the truth is that technology is not a panacea, but it may be able to assist official efforts at an unprecedented time. However, no technological solution can succeed without two specific factors: public trust and buy-in, and rapid, widespread testing for everyone living in the U.S. To achieve the first, a number of factors must be addressed by officials in the states looking to implement digital solutions, and by technology developers.

The Risks and Rewards of Emerging Technology in Nuclear Security

| February 2020

Nuclear security is never finished. Nuclear security measures for protecting all nuclear weapons, weapons-usable nuclear materials, and facilities whose sabotage could cause disastrous consequences should protect against the full range of plausible threats. It is an ongoing endeavor that requires constant assessment of physical protection operations and reevaluation of potential threats. One of the most challenging areas of nuclear security is how to account for the impact–positive and negative—of non-nuclear emerging technologies. The amended Convention on the Physical Protection of Nuclear Material (amended CPPNM) states it should be reviewed in light of the prevailing situation, and a key part of the prevailing situation is technological evolution. Therefore, the upcoming review conference in 2021, as well as any future review conferences, should examine the security threats and benefits posed by emerging technologies.

The study of existential risk — the risk of human extinction or the collapse of human civilization — has only recently emerged as an integrated field of research, and yet an overwhelming volume of relevant research has already been published. To provide an evidence base for policy and risk analysis, this research should be systematically reviewed. In a systematic review, one of many time-consuming tasks is to read the titles and abstracts of research publications, to see if they meet the inclusion criteria. The authors show how this task can be shared between multiple people (using crowdsourcing) and partially automated (using machine learning), as methods of handling an overwhelming volume of research.
