Shortages in the supply of quality early generation seed (EGS) of new and improved varieties, particularly of dryland cereals and legumes is a major challenge because of the business models.This triggers the following questions: what EGS business models would sustainably avail quality parent seed? To investigate this, we documented 16 EGS interventions. We found that pre-securing seed market ahead of production played important role in the successful seed business. Taking different forms (e.g., pre-orders, demand forecasting, pre-aggregation of demand, joint planning,contractual agreement), it brings confidence to EGS producers to continuously invest in the business and make it profitable. For sustainable EGS production and supply in sub-Saharan Africa, we advocate for marketassurance in advance. Two guiding principles are also suggested and four recommendationsformulated.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

This book analyzes the sustainability of community seed production under a rice–wheat farming system from microeconomic perspectives, considering how seed producers benefit from community seed production and how those benefits continue into the future. Seed producers’ performance in resource management, governance and marketing strategies indicates current benefits, whereas soil conservation and risk-management practices provide the basis for future benefits. Community seed production is a local-level seed management system owned by farmers. This system provides the institutional mechanism to supply diversified seed demands of open-pollinated varieties of food crops in a cost-effective way in rural regions. Being able to address the concerns of food insecurity, poverty, climate stress and biodiversity loss in programs and policies of development agencies, community seed production is gaining popularity among the farmers and the policy makers in developing countries. This book discusses the issues of organizational governance of the community seed producers’ groups and links them with household-level benefits to understand the organizational dynamism and the probable development paths of such organizations in the future. It also highlights the necessity to institutionalize lessons learned in community seed production in the stakeholders’ programs and policies. These understandings provide a basis for formulating policies for strengthening the system in developing countries. Students, researchers, policy makers and donor agencies working with CSP in the developing world will find this book useful in broadening their understanding of CSP in general and its sustainability in particular.

The book offers a rich toolkit of relevant, adoptable ecosystem-based practices that can help the world's 500 million smallholder farm families achieve higher productivity, profitability and resource-use efficiency while enhancing natural capital.
