“Population, Poverty, Environment, and Climate Dynamics in the Developing World,” in the Interdisciplinary Environmental Review, by Jason Bremner, David Lopez-Carr, Laurel Suter, and Jason Davis, attempts to illuminate and clarify the complex relationships between environmental degradation, population dynamics, and poverty. Population growth is a key driver for the degradation of ecosystem services which has a direct impact on livelihoods and human well-being, write the authors, especially for the poor. They argue that “population growth itself, however, remains an insufficient explanation of the relationship between population, ecosystems, and poverty.” While the field has a come a long way since its “original Malthusian roots,” they write, the relationships between these dynamics differ greatly depending on the area in question, and much work remains to be done on the less well-studied ecosystems.
