But there is a wider challenge: climate change and urbanisation are reducing the amount of fertile land capable of delivering life essentials and increasing the potential for weather and human conflicts to intensify commodity shortages and price spikes. Countries should be looking to make more of the green growth potential of their land, though the amount of exploitable land is likely to shrink. A key question, in the interests of the long-term global economy, is how countries will reconcile the competing pressures on land locally in a way that can contribute positively to the global imperative.
