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.

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.

African Regional Economic Integration

| Winter 2018

The power of Pan-Africanism as a guiding vision for the continent’s development is widely studied, mostly as an aspirational phenomenon. At worst, Pan-Africanism has often been seen as a poor imitation of American federalism or European integration. Both of these perceptions do not reflect the profound nature of the role that the ideology of Pan-Africanism played in shaping the continent’s economic transformation.

Spotlight on John P. Holdren

| Fall/Winter 2016-2017

As assistant to the president for science and technology, director of the White House Office for Science and Technology Policy, and co-chair of the President’s Council of Advisors on Science and Technology (PCAST), Holdren has worked closely with Obama to reinvigorate America’s scientific capabilities on a range of policy fronts, from climate change and renewable energy to health care and nanotechnology.

Climate Change: Voters Will Be Hot Under the Collar by 2099

| October 26, 2016

By 2099 the nature of democratic politics could change in costly ways for politicians because of climate change, according to Nick Obradovich, research fellow with Harvard Kennedy School’s Science, Technology, and Public Policy program. Leveraging a century’s worth of political science research, he predicts in an article in Springer’s journal Climatic Change that voters’ disgruntlement about the societal effects of climatic extremes and weather-related disasters they experience will translate into more frequent turnover of political parties elected in and out of office, and will keep politicians of especially warmer, poorer countries more on their toes than is currently the case.

Let's Reinvent and Diversify Africa's Universities to Make Them Centers of Innovation

| August 25, 2016

"Creating innovation universities can be pursued through three practical stages. The first is to formulate a policy framework under which such universities operate. The second state is to translate the policy into specific legislative reforms to support the new university species. The third stage is to experiment by upgrading a few research institutes that have strong foundations and potential to commercialize products and services."

African Voters Indicate Lack of Support for Climate Change Policies

| In Press

In this article — across two experimental studies — the authors find evidence that Sub-Saharan African politicians who commit to climate change policies may lose electoral support. Electorally important swing voters with weak party affiliations are least likely to support party statements about climate change. Interviews with standing elected officials from Malawi and South Africa corroborate the experimental findings. The combined results suggest voter preferences may hinder the successful implementation of climate change policy in Sub-Saharan African democracies.

New Research on African Regional Integration from the Science, Technology, and Globalization Project

| June 02, 2016

A new manuscript from the STG Project chronicles the adoption of the Tripartite Free Trade Area (TFTA) Agreement on June 10, 2015. Prof. Calestous Juma and Dr. Francis Mangeni argue that Africa is pursuing regional trade as part of a broader strategy for long-term economic transformation.
