e-infrastructure Roadmap for Open Science in Agriculture

A bibliometric study

The e-ROSA project seeks to build a shared vision of a future sustainable e-infrastructure for research and education in agriculture in order to promote Open Science in this field and as such contribute to addressing related societal challenges. In order to achieve this goal, e-ROSA’s first objective is to bring together the relevant scientific communities and stakeholders and engage them in the process of coelaboration of an ambitious, practical roadmap that provides the basis for the design and implementation of such an e-infrastructure in the years to come.

This website highlights the results of a bibliometric analysis conducted at a global scale in order to identify key scientists and associated research performing organisations (e.g. public research institutes, universities, Research & Development departments of private companies) that work in the field of agricultural data sources and services. If you have any comment or feedback on the bibliometric study, please use the online form.

Private Contracting versus Community Seed Production Systems: Experiences from Farmer-Led Seed Enterprise Development of Indigenous Vegetables in Tanzania


The growing scourge of malnutrition due to unhealthy and imbalanced diets has led to increased public health awareness and advocacy for diversifying diets with highly nutritious indigenous vegetables and fruits. Several studies have shown that indigenous vegetables rich in micronutrients, vitamins, antioxidants, and other health-related phytochemicals with antibiotic, probiotic and prebiotic properties can play a key role in addressing human nutrition and development. However, a major reason for the low adoption of indigenous vegetables from Africa is the inability of formal, centralized seed production systems to meet their complex and diverse seed requirements. Drawing on experiences in Tanzania with amaranth, African nightshade and African eggplant, this paper provides a preliminary assessment of the viability of seed production under two farmer-led seed enterprise models, namely, contract seed production with seed companies, and the community-led Quality Declared Seed production systems. Both are examined as strategies for economically viable and sustainable distribution and promotion of indigenous vegetable crops. The assessment is based on participatory learning, action research and outcome mapping tools. Preliminary analysis shows that on average community seed producers have a lower input cost and higher returns than contract seed growers. While seed companies operate in a dynamic business environment and have profit-oriented motives that might contravene development objectives envisaged under the proposed seed contract model, the community seed production system may also encounter challenges in identifying and establishing viable market linkages. The two farmer led seed enterprise models investigated have potential for higher income earning opportunities at both the farmer and community levels. Inaccessibility of indigenous vegetable germplasm, lack of technical know-how, institutional bottlenecks, lack of strong collaborative links between seed sector stakeholders, and the need for an enabling national seed policy and regulatory environment must be addressed to successfully implement and scale up this approach.
