Rapid population growth, climate change, intensive monoculture farming, and resource depletion are among the challenges that threaten the increasingly vulnerable global agri-food system. Heavy reliance on a few major crops is also linked to a monotonous diet, poor dietary habits, and micronutrient deficiencies, which are often associated with diet-related diseases. Diversification—of both agricultural production systems and diet—is a practical and sustainable approach to address these challenges and to improve global food and nutritional security. This strategy is aligned with the recommendations from the EAT-Lancet report, which highlighted the urgent need for increased consumption of plant-based foods to sustain population and planetary health. Bambara groundnut (Vigna subterranea (L.) Verdc.), an underutilized African legume, has the potential to contribute to improved food and nutrition security, while providing solutions for environmental sustainability and equity in food availability and affordability. This paper discusses the potential role of Bambara groundnut in diversifying agri-food systems and contributing to enhanced dietary and planetary sustainability, with emphasis on areas that span the value chain: from genetics, agroecology, nutrition, processing, and utilization, through to its socioeconomic potential. Bambara groundnut is a sustainable, low-cost source of complex carbohydrates, plant-based protein, unsaturated fatty acids, and essential minerals (magnesium, iron, zinc, and potassium), especially for those living in arid and semi-arid regions. As a legume, Bambara groundnut fixes atmospheric nitrogen to improve soil fertility. It is resilient to adverse environmental conditions and can yield on poor soil. Despite its impressive nutritional and agroecological profile, the potential of Bambara groundnut in improving the global food system is undermined by several factors, including resource limitation, knowledge gap, social stigma, and lack of policy incentives. Multiple research efforts to address these hurdles have led to a more promising outlook for Bambara groundnut; however, there is an urgent need to continue research to realize its full potential.

Background The main purpose of this paper is to understand the multidimensional phenomenon of the nutrition transition in Malaysia, from 1980 to 2014, to inform future policies for a healthier nation. Methods Food and health data were obtained through Food Balance Sheets, Malaysian Adult Nutrition Survey (MANS) and National Health and Morbidity Surveys (NHMS) for year-to-year review. Interaction between changes in food supplies and dietary trends and the progression of diet-related diseases and risk factors in tandem with demographic and socioeconomic transitions were observed using quasi-historical approach. Results The period-under-review has seen Malaysia becoming more affluent, urbanised and modernised. Energy supply for Malaysian population remained consistently in excess of average calorie needs by a minimum of 30%. There were significant signs of shifting food trends, particularly in the supply of wheat (+ 56.5%), rice (− 23.7%), sugar and sweeteners (+ 23.9%), meat (+ 49.3%), fish and seafood (+ 38.7%), and eggs (+ 55.7%). The plant/animal protein ratio has decreased over time. Prevalence of NCD and associated risk factors has increased rapidly, some as high as 170%, despite various policy efforts to reduce them. Conclusion The study highlights the importance of policymakers taking a relook into its policies and strategies, and formulate sustainable, comprehensive and multifaceted actions together with all relevant stakeholders to ensure a conducive, healthy and nutritious food systems and environment for its population.

While China has transformed its economy over recent decades, challenges such as climate change and land degradation have continued to impact its agriculture. These effects along with changes in diets and growing food imports will force China to look for alternative cropping options. Despite the broad potential of Bambara groundnut (Vigna subterranea L. Verdc) as a resilient and nutritious underutilized crop, less is known about its potential in Asia. Here, we explore the potential of Bambara groundnut to become a mainstream crop in mainland China. A suitability analysis is presented for Bambara groundnut to examine the degree of seasonal adaptability of this crop against its climate and soil requirements across China. Results showed that the crop has yield potential in areas that can be too marginal for production of other mainstream crops such as soybean (Glycine max). If realized, the potential of Bambara groundnut could contribute to China's agriculture and reduce its reliance on vegetable protein imports. Using an average seasonal potential yield of 0.85 t/ha over a potential available area of between 55 and 112 million ha (based on 4 land availability scenarios) and modest price of 143 USD/t, yearly income between USD 6 and 13 billion can potentially be contributed by widespread cultivation of this crop. As well as food security, this drought‐resistant nitrogen‐fixing legume could also contribute to land rehabilitation, particularly in the areas where shift in planting dates and land degradation is noticeable. This study demonstrates the need for more investment and research into adoption of Bambara groundnut and other underutilized crops that have the potential to transform agriculture in populous Asian countries.

This study was designed to generate baseline data of the fish and seafood consumption pattern among major ethnics in urban, rural, and coastal regions of Peninsular Malaysia. A food frequency questionnaire was adapted and administered on healthy adult participants above 18 years. Fish and seafood is the prime animal protein source in Malaysian diet, comprising about one-third of total animal protein consumed. Average per capita fish and seafood consumption is 44.53kg/year, with higher levels observed in coastal (51.9kg/year) and rural (51.8kg/year) than urban areas (36.9kg/year). While the fish and seafood intake is relatively high, the total polyunsaturated fatty acids intake is borderline low. Despite cross- cultural and regional variations, there is a great overall preference for wild caught marine pelagic fishes. The demand has to be satisfied by imports, even after increasing local fishing effort. The data are beneficial for sustainability assessment and to inform policies for a sustainable food future

Marginal environments are characterized by constrained agricultural potential and resource degradation attributable to biophysical and politico-socio-economic factors. These environments and the indigenous people who cultivate them rarely attract academic interest, policy studies or investment. The agricultural expertise of indigenous communities is often overlooked by decision-makers. Interventions based on mainstream crops and external technologies may fail indigenous communities where a vast range of crops are cultivated in diverse production systems and in marginal environments. Hunger, malnutrition, and poverty in indigenous communities are high. The challenges should be approached from the perspectives and resources of indigenous people. In this chapter, we discuss four biogeographical regions, arid, semi-arid, humid and mountainous, representing large parts of marginal lands and innovations, investment opportunities, and proposed action for the transformation of food systems in these areas. Marginal areas and indigenous people can benefit from improved linkages between formal and indigenous knowledge systems, participatory and demand-driven technologies, integration of indigenous knowledge in research, improvements in local crops, integrated management and access to markets. Our recommendations for the transformation of food systems in these areas include (1) Efforts to mainstream diverse value chains, (2) Development of evidence-based policies (3) Awareness of under-utilized and forgotten crops (4) Collective action and (5) Coordinated public and private investment in research and development for the empowerment of indigenous people and the development of their land.
