Today, sustainability is all the rage. But when and why did the idea of sustainable development emerge, and how has its meaning changed over time?Stephen Macekura’s new book, Of Limits and Growth: The Rise of Global Sustainable Development in the Twentieth Century (Cambridge University Press, 2015) explores this question by connecting three of the most important aspects of the twentieth century: decolonization, the rise of environmentalism, and the pursuit of economic development and modernization in the Third World. Macekura, who is an Assistant Professor of International Studies at Indiana University, demonstrates how environmental non-governmental organizations (NGOs) attempted to promote environmental protection in the post-colonial world, then, after failing to do so, challenged the economic development approaches of the United States, World Bank, and United Nations. The book reveals how environmental activists initially conceived of “sustainable development” as a way to link environmental protection with Third World concerns about equality and justice in the global economy, but how, over time, the phrase’s meaning moved far away from this initial conception.In addition to exploring the idea of “sustainable development,” Macekura also examines the growth and limits of the environmental movement’s power. He pays close attention to how international political disputes have scuttled major global treaties over issues such as climate change; he also documents the evolution of international development politics and policy since 1945. In sum, Of Limits and Growth offers a new history of sustainability by elucidating the global origins of environmental activism, the ways in which environmental activists challenged development approaches worldwide, and how environmental non-state actors reshaped the United States’ and World Bank’s development policies.
