Physical control of insect pests in the horticultural crops
The global objective is to reduce the use of chemical pesticides in horticultural crops in Sub Saharan
Africa. The aim is first to develop insect proof nets with smallholder growers for the protection of
horticultural crops to reduce pesticide use and, secondly, to combine this technology with biological
control methods in a push pull strategy.
Research on the biological efficacy of the nets on
insects (as a visual and physical barrier), on their
combination with other biological control
methods (i.e. repellent companion plant), on their
effect on various crops (micro-climate, water
consumption, plant physiology, diseases, yield
and quality of production), on their management,
and on the socio-economic aspects linked to their
adoption (labour demand, cost/profit analysis),
or promotion (impact on the environmental and
public health).

Climate change and Management of coffee pests and diseases in
the agroforestry systems of Eastern Africa
The aim is to conceptualize and establish a risk
model for the coffee crop in response to various
changes, either social (market access, farmers’
organizations, land tenure, etc), or environmental
(climate, biodiversity, shade management, etc) in
Eastern Africa.
