Robust cropping systems to tackle pests under climate change. A review


Date: 10/03/2015


This article reviews the effects of climate change on crop protection and strategies to reduce the impact of future invasive crop pests as well as those of rapidly evolving resident populations. The authors make the following points: (i) the consequence of climate change and globalization is a heightened level of unpredictability of interactions between weather, cropping systems and pests; (ii) the unpredictable adaptation of pests to a changing environment creates uncertainty and projected changes do not automatically translate into doom and gloom scenarios; (iii) faced with uncertainty, policy, research, and extension should prepare for worst-case scenarios following a ‘no regrets’ approach that promotes resilience vis-à-vis pests; (iv) farmers can take advantage of Web 2.0 and other new technologies to make the exchange of updated information quicker and easier; and (v) cooperation between historically compartmentalized experts in plant health and crop protection could help develop anticipation strategies.
