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.

Deep Decarbonization Roadmap for the Cement and Concrete Industries in California

| September 2019

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

What Digital Nerds and Bio Geeks Have to Worry About

| Sep. 13, 2019

The authors explain how the risks of computer systems are transferring to biological systems. The difference is that biological systems have the potential to cause a greater degree of damage than computer systems. Stringent biocontainment helps, but no containment system provides zero risk.

A Call for Realism in Europe

| May 27, 2018

Strategic thought in Europe is underdeveloped. Hard power and military force remain beyond the scope of many Europeans. That is a problem because the extent to which Europeans can understand the world determines the extent to which they can exert influence. The United States are in a relative decline and there is no guarantee that Washington will protect Europe against the rise of China, the threat from Russia, and/or the instability from the Middle East. Europe will have to stand upon its own feet and take responsibility for its own fate. Doing so not only requires significant investment in military resources, but also a renaissance of European realist thought.

Remembering Our Colleague Professor Calestous Juma

Our colleague Calestous Juma—who passed away on December 15 at age 64 after a long illness—was a pioneering, prolific, and influential scholar/practitioner in science and technology policy for sustainable well-being. He joined Harvard Kennedy School (HKS) in 1999 as Director of the Science, Technology, and Innovation Project (a joint venture of the Belfer Center for Science and International Affairs and the Center for International Development) and became Professor of the Practice of International Development in 2002, a position in which he maintained his exceptional productivity and engagement with policy, despite illness, up to the time of his death.

Why President Trump Needs to Finally Name a Science Advisor

| Apr. 05, 2017

"Every president stocks the White House with people who can advise him on the economy, national defense, and foreign relations. And nearly all presidents in modern times have understood that science and technology are so central to all of those top-tier issues — and practically every other issue on the nation’s agenda — that science and technology advice in the White House is no less essential."

Revolution in Africa

| December 16, 2016

"Sustaining African agricultural transformation will require national policy approaches which emphasize the need to transition toward sustainable agriculture. More specifically, they will need to pursue strategies that allow for the integration of precision agriculture in existing farming methods. Such policies could focus on six key elements: biological diversity; ecology and emerging technologies; infrastructure; research and training; entrepreneurship and regional trade; and improved governance of agricultural innovation."
