“…Integrative research and education efforts can be led by, or codesigned with, the specific human communities who hold relevant plant knowledge and tend key wild and domesticated landscapes. Participatory modeling approaches may support agrobiodiversity through building stakeholders’ understanding and ideas about management ( 117 ), and participatory plant breeding may support agrobiodiversity through engaging many agronomic environments ( 118 ). Citizen science can be used to collaboratively collect crop and ecology data and to invite social learning, all of which may be useful for studying and advancing domestication ( 90 , 119 , 120 ), though agricultural citizen science efforts need to consider low-income contexts and the Global South ( 121 ).…”

Current food systems are challenged by relying on a few input-intensive, staple crops. The prioritization of yield and the loss of diversity during the recent history of domestication has created contemporary crops and cropping systems that are ecologically unsustainable, vulnerable to climate change, nutrient poor, and socially inequitable. For decades, scientists have proposed diversity as a solution to address these challenges to global food security. Here, we outline the possibilities for a new era of crop domestication, focused on broadening the palette of crop diversity, that engages and benefits the three elements of domestication: crops, ecosystems, and humans. We explore how the suite of tools and technologies at hand can be applied to renew diversity in existing crops, improve underutilized crops, and domesticate new crops to bolster genetic, agroecosystem, and food system diversity. Implementing the new era of domestication requires that researchers, funders, and policymakers boldly invest in basic and translational research. Humans need more diverse food systems in the Anthropocene—the process of domestication can help build them.

“…Crop genetic diversity in genebanks is fundamental for demand-driven breeding. Genebanks supply diversity of local crop populations, which have coevolved with local conditions and show potential for continued evolution, as well as genes to address emerging diseases and other challenges ( 20 , 21 ). FAO WIEWS indicates that there are more than 5.7 million accessions stored in 831 genebanks around the world, which represents a large amount of diversity.…”

This perspective describes the opportunities and challenges of data-driven approaches for crop diversity management (genebanks and breeding) in the context of agricultural research for sustainable development in the Global South. Data-driven approaches build on larger volumes of data and flexible analyses that link different datasets across domains and disciplines. This can lead to more information-rich management of crop diversity, which can address the complex interactions between crop diversity, production environments, and socioeconomic heterogeneity and help to deliver more suitable portfolios of crop diversity to users with highly diverse demands. We describe recent efforts that illustrate the potential of data-driven approaches for crop diversity management. A continued investment in this area should fill remaining gaps and seize opportunities, including i) supporting genebanks to play a more active role in linking with farmers using data-driven approaches; ii) designing low-cost, appropriate technologies for phenotyping; iii) generating more and better gender and socioeconomic data; iv) designing information products to facilitate decision-making; and v) building more capacity in data science. Broad, well-coordinated policies and investments are needed to avoid fragmentation of such capacities and achieve coherence between domains and disciplines so that crop diversity management systems can become more effective in delivering benefits to farmers, consumers, and other users of crop diversity.

“…Biodiversity in general and agrobiodiversity in particular are crucial for adaptation to climate change, for resilience and for human health as related to dietary diversity [47]. Chaudhary et al [6] proposed utilization of crop wild relatives, farmer's fields, community seed bank, participatory crop improvement, and value addition of underutilized crops to be methods of in situ conservation while research stations, botanical garden, and national and international gene bank to be methods of ex situ conservation.…”

The agricultural sector is challenged to fulfill the nutritional requirements of ever-increasing population. Rates of growth in crop productivity have declined, among many reasons is due to climate change and the decline of water and land resources. Dependence by 50% on few cereal crops like wheat, maize and rice for total food intake and calorie requirements has countersigned loss of biodiversity and decline in crop productivity. The genetic diversity of traditional crop varieties offers resilience to environmental risks, socioeconomic shocks, adaptation and mitigation to climate change which is crucial for crop production. Traditional African Vegetables (TAVs) are an integral constituent of the diets of many rural and urban communities. They are important sources of essential macro and micro-nutrients. In addition, they offer a source of livelihood when marketed, and also contribute to crop biodiversity. Tanzania needs to conserve the Traditional African vegetables and their genetic resources against stressful conditions and increased selection pressures which causes loss of genetic variation and a decrease in fitness by a process called genetic erosion. Conservation and use alleviate genetic drift and inbreeding depression, then, is critical to guarantee TAVs persistence in rural areas. This review explores agrobiodiversity of traditional African vegetables (TAV) from livelihood of Tanzanian rural communities’ perspectives and how the country has managed to conserve these species.
