Welcome to GDAE’s website!

This website presents GDAE’s current research and educational efforts in three areas: Land, Energy, and ClimateGreen Economics, and educational materials in Environmental and Natural Resource Economics.

Publications reflecting GDAE’s earlier research in areas such as globalization, trade and feminist economics, including Policy Briefs and Discussion papers, can be found in our Resource Directory. All GDAE books and working papers are also available.

Other educational materials, including the “In Context” texts and free modules, developed at GDAE can now be accessed at their new location at the Economics in Context Initiative at Boston University’s Global Development Policy Center.

Climate Change, Social Equity, and the Green New Deal

August 14, 2020

GDAE Senior Researcher Jonathan Harris is quoted extensively in a new article on social equity and the Green New Deal.  He argues that the political presentation of the Green New Deal has improved, stressing its practical advantages especially for low-income earners.  A Green New Deal has the potential to create millions of jobs, while employing policy measures that are low cost and can have immediate impact.  The COVID crisis increases the urgency of a broad Federal response both to unemployment and to the health crisis.  The article builds on an earlier presentation about Transitioning to a Low-Carbon Economy.  See also Harris’s policy brief on Ecological Economics of the Green New Deal and other research by GDAE on Green Economics.


Two New Policy Briefs on Soils and Climate

July 13, 2020

Policies to promote healthy soils are central both for climate policy and agricultural sustainability. Following two conferences on the topic, GDAE researchers present two policy briefs, one by Sam Polzin on Soil Carbon, Water Management, and Natural Infrastructure and one by Benjamin Johnson on Land Value and Soil Quality.  They advocate:

  • Regionally coordinated state-level agricultural policy incentives to enhance both soil health and water management in the Northeastern United States by harnessing the potential for agriculture to build natural infrastructure.
  • Reforming current systems of land valuation and taxation to reflect soil quality and long-term productive potential, creating landowner incentives for proper stewardship.

See Healthy Soils conference reports and other related climate policy briefs.

Moomaw Appeals to the EU Parliament for Climate-Focused Forest Management

May 22, 2020

GDAE Co-director William Moomaw has drafted a letter to the European Parliament emphasizing forest management as an effective tool to reduce atmospheric carbon.  Forests remove more carbon from the atmosphere than any other planetary system, but this storage potential is threatened by human activities. Long-term carbon storage in forests is critically important in order to achieve both EU and global climate targets.

The letter has been signed by 370 scientists from 34 countries who have a range of expertise spanning multiple dimensions of climate, forests, energy, carbon cycle accounting and biodiversity. Signers include some of the senior scientists who warned about the consequences of climate change during the 1970s and 80s, leading scientists of today, and younger scientists who are studying to be able to offer their talents to nature’s climate solutions.

GDAE Co-Director Sponsors Letter Urging Congress to Protect Forests

May 13, 2020

GDAE Co-Director Dr. William Moomaw has sponsored a letter urging Congress to protect forests in the United States and shift away from wood consumption in an effort to reduce carbon emissions.  The letter has been signed by more than 200 climate and forest scientists.

The letter is further discussed here.

Transitioning to a Low-Carbon Economy

May 12, 2020

GDAE research is extensively cited in a new article on the Green New Deal and the transition to a low-carbon economy. The article argues that a Green New Deal can produce both environmental and economic benefits and quotes extensively from GDAE researcher Jonathan Harris. See also Harris’s related Climate Policy Brief.

Responding to Climate Change in Japan

March 31, 2020

GDAE Visiting Scholar David Sussman writes that climate change is threatening important cultural aspects of Japanese life, yet most people in the country have not taken actions to limit their carbon emissions.


In this op-ed in the Nikkei Asian Review, Dr. Sussman calls for individual and systemic changes that will reduce wasteful consumption and fossil fuel dependence.

The Northeast Healthy Soil Network Hosts Symposium

February 21, 2020

This day-long symposium brought together policymakers, farmers, academics, and students with the goal of advancing healthy soils policies and practices throughout the northeast.

December 10, 2019

GDAE Co-director Dr. William Moomaw, co-author of the recent World Scientists’ Warning of a Climate Emergency, joins fellow scientist Youba Sokona, youth activists Greta Thunberg and Luisa Neubauer, and scientists Ko Barrett, Sivan Kartha, and Rachel Cleetus, on the stage at the United Nations COP25 climate conference in Madrid.

World Scientists’ Warning of a Climate Emergency
November 5, 2019

William Moomaw co-authored a paper published in the journal BioScience. In the paper, Moomaw and his co-authors declared a climate emergency that without deep and lasting shifts in human activities will result in “untold human suffering”. The authors present a suite of graphical vital signs of climate change over the last 40 years for human activities that can affect GHG emissions and change the climate, as well as actual climatic impacts. The paper is endorsed by 11,258 scientists from 153 countries.

The paper has been covered by The Washington Post, The Guardian, The Boston Globe, and USA Today.

Rome Summit Takes Bold Step Toward Agroecology
October 24, 2019

Common Dreams published an article by Timothy A. Wise on agroecology and its role as one of the cutting-edge innovations we need to help small-scale farmers adapt to climate change.


Why Keeping Mature Forests Intact Is Key to the Climate Fight
October 15, 2019

GDAE Co-Director Dr. William Moomaw was interviewed by Yale Environment 360 about the importance of existing forests and why the push to cut them for fuel to generate electricity is misguided.
