10 Conservation and Family Planning go hand in hand | Interview with Robert Engelman
Ibadan, Nigeria ➤ Population growth affects global environmental change. Other things being equal, an increase in the world’s population will lead to more carbon emissions, more deforestation and less biodiversity; but arguments of this kind are too simplistic and other things are not equal. The effects can go in both directions: environmental change can influence population growth. As has long been recognized, e.g. the IPAT model (Ehrlich and Holdren 1971), it is not just adding people that matters, but also how those people produce and consume. To see this, imagine adding 10 hunter and gatherers to the world’s population versus adding 10 men with chainsaws driving Land Rovers and living in 3,500 sq ft (325 sq m) houses. Furthermore, institutions (local, national and/or global) can mitigate or exacerbate the effects of population change (Dietz, Ostrom and Stern 2003). Finally, it also matters whether people are organized into a small number of larger households or a large number of smaller households. To understand population-environment relationships, we need to link population change to consumption, production, and institutions. Before tackling this complexity it is important to understand basic population trends. This paper, painting with broad brush strokes, reviews recent trends and speculates about the future.

POPULATION GROWTH
The elements of population growth are conveniently summarized by the following basic equation: Popt2 = Popt1 + (Births – Deaths) + (In-migrants – Out-migrants) ➤
