An approach to establishing improved private extension-service provision for smallholder horticultural producers in Kenya was developed between 2003 and 2005 by the International Centre of Insect Physiology and Ecology and Natural Resources Institute in the UK, in collaboration with EurepGAP FoodPLUS GmbH and the House of Quality–South Africa, international NGOs, export companies, and out-grower farmer groups. The approach focused on good agricultural practices, food safety, EU regulations on maximum pesticide-residue limits, and the EurepGAP Standard. The approach is not a blueprint, but the lessons learned are applicable to similar smallholder production systems in other African countries.  相似文献
