Trade-offs between conservation and land use

Whether to strictly protect large areas of natural ecosystems and intensify farming on the remainder (land sparing) or to protect less land and farm at lower intensity on a larger area (land sharing) is a hotly debated topic in Conservation Biology. A new paper by Van Butsic which has just been published with Conservation Biology provides new insights to this debate. Coupling an economic model with species-area models and considering a range of response functions, Van's results show that species richness responds in highly non-linear ways for both land use strategies, and that the optimal solution may be highly context specific.
