    Scientific review of the impact of climate change on plant pests
    A global challenge to prevent and mitigate plant-pest risks in agriculture, forestry and ecosystems
    2021
    Climate change represents an unprecedented challenge to the world’s biosphere and to the global community. It also represents a unique challenge for plant health. Human activities and increased market globalization, coupled with rising temperatures, has led to a situation that is favourable to pest movement and establishment. This scientific review assesses the potential effects of climate change on plant pests and consequently on plant health. The evidence assessed strongly indicates that climate change has already expanded some pests’ host range and geographical distribution, and may further increase the risk of pest introduction to new areas. This calls for international cooperation and development of harmonized plant protection strategies to help countries successfully adapt their pest risk management measures to climate change.

    Climate change is having an impact on ecosystems and agricultural production systems throughout the world. It influences international trade flows of plants and plant products and it will change the infectivity, severity and distribution of plant pests throughout the world. Preventive, mitigation and adaptation measures by national plant protection organizations (NPPOs) and regional plant protection organizations (RPPOs) are essential to limit the international spread of pests adapting to climate change.Climate-change impacts on ecosystems, pests and vectors also threaten the international trading system, as international trade provides a pathway for pests and vectors to spread into new areas of the world. To facilitate safe international trade in plants and plant products, it is therefore imperative to strengthen national, regional and international phytosanitary capacities regarding climate change. The aim of this document is to provide technical and operational advice to NPPOs and RPPOs on how to effectively assess and manage the pest risk that is a consequence of climate change.

    Impact evaluation (IE) enables programme managers and policymakers to plan interventions in a rational and evidence-based manner. While a range of evaluation methods exists, this briefing note provides an overview of rigorous and quantitatively sound IE methods. These methods provide programme managers and policymakers thorough evidence on the impact of adaptation interventions, allowing them to make informed policy choices on adaptation options. By engaging in detailed, evidence-based evaluation, policymakers and programme managers can address critical elements for the formulation and implementation of the National Adaptation Plans (NAPs).
