CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Perceptions of Climate Variability and Pest-Disease Incidence on Crops and Adaptive Forest-Agricultural Practices

Exporter la citation

The article examines the influence of local perceptions of climate variability and pest–disease incidence on crops and its management and on adaptive forest–agricultural practices. The study was conducted in the humid forest of Southern Cameroon along a resource use intensification and population gradient using a semi-structured questionnaire administrated to farmers. The results showed that the level of severity of crops–pests incidence was perceived as high, with an increase over the past 15 years. A high incidence of pests–diseases was perceived on yield/income of cocoa, cassava, and groundnuts. The results indicated that each crop has its management practices of pests–diseases both at the crop and land use level. The farmers respond positively to their perception of climate variability by anticipating cropping practices, by harvesting earlier or later, and by adapting strategies of pests–diseases with crops and land use practices that affect the sustainability of forest–agriculture.
