CLIMAPEST - Impacts of climate change on plant diseases, pests and weeds


Period: 2009 a 2012

Leader: Raquel Ghini (Embrapa Environment)

Vice-leader: Emília Hamada(Embrapa Environment)


Climate change is considered one of humankind’s greatest challenges in the near future. The climate change is expected to interfere on the current scenario of pests of Brazilian agriculture. Once the environment determines the occurrence of diseases, arthropod-pests and weeds, climate change can modify their occurrence and severity. The economic, social and environmental impacts of climate change can be positive, negative or neutral, since these changes can decrease, increase or have no impact on plant diseases, pests or weeds depending on each region or period of time considered.

Plant pathogens and pests are among the first organisms to show the effects of climate change due to high populations, ease of propagation and dispersal and the short time between generations. Thus, these groups of key indicators must be evaluated for the impacts of climate change. Besides, they are also responsible for reduced productivity and sustainability of the agroecosystem. Consequently, it is extremely important to carry out detailed studies on the effects of climate change on plant diseases, pests and weeds.

The project “Impacts of climate change on plant diseases, pests and weeds” (CLIMAPEST) is linked to the Macroprogram 1 Great National Challenges, as part of the Brazilian Agricultural Research Corporation (Embrapa) System of Project Management (SEG). The SEG has been designed to provide the necessary tools to manage the whole life cycle of Research and Development Projects, as they are: planning, financial resources release, conduction, follow ups and final evaluation. It also provides Embrapa with a better organizational flexibility and transparence in generating technology. Research and Development strategic projects conducted in a multiinstitutional complex array, requiring a high volume of resources are the main features of the projects that compose the Macroprogram 1 portfolio. These projects are characterized for high technical and scientific quality in the basic and applied research.
