A concerted effort is needed to fully realize the potato's potential to help improve livelihoods, reduce poverty and enhance food security in Kenya. Full implementation of the policy guidelines presented in Policymakers' Guide to Crop Diversification can stimulate accelerated growth in potato production and use, and make an important contribution to helping producers and consumers reap the benefits of doing so. While aimed primarily at policymakers in Kenya, Policymakers' Guide to Crop Diversification is also of use to decision-makers at institutional and policy levels in other countries of Eastern and Central Africa. It will help the realization of the potato's full potential as a high-value crop in response to emerging opportunities, such as changes in consumption pattern and the resulting need for value addition due to rapid urbanization, and to potential threats, including climate change and food price surges causing upheaval in international food markets.
