Although there are over 4000 potato cultivars in the world, only a few have been commercialized due to their marketability and shelf-life. Most noncommercialized cultivars are pigmented and found in remote regions of the world. White-fleshed potatoes are well known for their energy-enhancing complex carbohydrates; however, pigmented cultivars are potentially high in health-promoting polyphenolic compounds. Therefore, we reveal the comprehensive compositions of pigmented cultivars and associated potential health benefits, including their potential role in ameliorating hunger, food, and nutrition insecurity, and their prospects. The underutilization of such resources is a direct threat to plant-biodiversity and local traditions and cultures.

The mission of the World Vegetable Center (WorldVeg) is research and development to realize the potential of vegetables for healthier lives and more resilient livelihoods. WorldVeg operates across Asia and Africa, and its breeding portfolio comprises global as well as traditional vegetables. Cucurbit crops make an important contribution to global food and nutrition security and are economically important to smallholder farmers in Asia, who account for 83% of global cucurbit production. The global cucurbit breeding program of WorldVeg focuses on four species: bitter gourd (Momordica charantia), tropical pumpkin (Cucurbita moschata), ridge gourd (Luffa acutangula), and sponge gourd (Luffa cylindrica syn. L. aegyptiaca). Improved cultivars have been developed by the private seed industry, however, repeated recycling of lines derived from elite hybrids has narrowed the genetic base and reduced genetic gains for yield and other key traits. This trend will continue unless a concerted effort is made to introduce new genetic variability into elite hybrids. WorldVeg has organized a breeding consortium with seed companies to facilitate access to the Center’s new breeding lines derived from hitherto unexploited landraces to develop genetically diverse, improved cucurbit cultivars with enhanced yield and resistance to major diseases. Through this partnership, WorldVeg presents its improved lines and F1 hybrids at Crop Field Days for selection by private seed industry staff engaged in breeding, product development, and sales and marketing.

Today's predominant food system on the one hand produces plenty of food, making food relatively cheap for most people in the world. However, for many people, the food they can afford is insufficiently nutritious. Major global health problems like obesity are partly a result of the present food system. Furthermore, the modern industrial way of producing food has negative environmental consequences, consisting among others of a decline in soil fertility and a loss of biodiversity. Another food system is required to obtain sustainable global food and nutrition security. This food system should observe the normativity of the agricultural practices that produce food. The authors' analysis of agricultural practices shows that the farm is economically qualified but that the primary process of care for soil, crops, and animals can best be seen as an ethically qualified supporting practice that steers the “meaningful shaping” of the interventions foundational for agricultural practices.

ABSTRACT The present study systematized the experience gained with the project Construindo capacidades em segurança alimentar e nutricional no Brasil, Canadá e Angola (2004-2010, Building food and nutrition security skills in Brazil, Canada, and Angola), whose objective was to qualify actions that promote food and nutrition security in the three countries using different educational practices. The activities were organized in the following subprojects: (a) online distance learning courses; (b) workshops to train managers, government technicians, representatives of civil society organizations, and social subjects who offered to act as a link between communities; and (c) local pilot projects. The present study reports this experience. The educational practices implemented in the municipalities of Araçuaí (MG), Juazeiro (BA), and Fortaleza (CE) were analyzed based on systematized information in the project reports and activity records (texts and photographs). The analytical reference was based on the concept of food and nutrition education, guided by the fundamentals of Popular Education and Paulo Freire; on the concept of food and nutrition security; and on the following analytical dimensions: participation, contextualization of educational practices, and intersectoriality. The results evidenced how educational practices contributed to the construction of shared concepts of food and nutrition security from an intersectoral and participatory perspective that values the peculiarities of diet in different socioeconomic and cultural contexts, and highlights daily situations and local traditions. They also expose the limits and potentialities of an experience of this magnitude, conducted from an interdisciplinarity perspective and using participatory methods.

Millets are climate-resilient crops adaptable to wide variety of ecological conditions requiring less water for irrigation with better growth and productivity in low nutrient soils.  They require low artificial fertilizers application and show minimal vulnerability to environmental stresses. There is need to revive the importance of millet groups as health foods to enhance food and nutritional security. Millets contain high amounts of proteins, fiber, niacin, thiamine and riboflavin, methionine, lecithin and little of vitamin E. They are rich in minerals like iron, magnesium, calcium and potassium also. Millets due to their nutritive value have potential health benefits to prevent cancers, decrease the occurrence of cardiovascular diseases, reduce tumor proliferation, lower blood pressure, risk of heart diseases, cholesterol content, rate of fat absorption, delayed gastric emptying and increased gastrointestinal bulk. Value-addition to millet grains as ready-to-eat and ready-to-cook items offers good opportunity to farmers for enhanced income generation, promotes production and marketing leading to nutritional security, employment and revenue generation.

The aim of the study was to analyze the chemical composition of new artichoke cultivars and hybrids and to assess their potential health-promoting properties. Polyphenols, carotenoids and chlorophylls were identified by liquid chromatography-photodiode detector-mass spectrometry/quadrupole time of flight (LC-PDA-MS/QTof) and quantified by ultra performance liquid chromatography-photodiode detector (UPLC-PDA). Sugar and organic acid profiles were prepared, and antioxidant capacity (ABTS, FRAP and ORAC) and in vitro antidiabetic (inhibition of α-amylase and α-glucosidase) and anticholinesterase (inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE)) potentials were evaluated. The analyses revealed a highly varied content of bioactive compounds and great health-promoting potential significantly depending on a cultivar. The content of polyphenolic compounds ranged from 1681.49 (“Sambo”) to 3638.91 (“Symphony”) mg/100 g of dry weight (DW). “Blanca de Tudela” contained the highest amounts of carotenoids and chlorophylls (3761.91 mg/100 g DW) and exhibited high ABTS and ORAC capacity. Inhibition of antidiabetic enzymes was significant in cvs. “Symphony” and “Calico”. Additionally, all tested cultivars and hybrids turned out to be effective inhibitors of neurodegenerative enzymes.

Indonesia is known for its multicultural social setting, with approximately three hundred local ethnicities and five hundred local languages. Religions also have infiltrated into the life of Indonesia. Among six officially recognized religions, Islam occupies the majority religion in the country, and the total number of Muslims is almost two hundred million. That makes Indonesia the most populous Muslim country in the world. However, we also know that the legacy of pre-Islamic civilizations, such as Hinduism, Buddhism, and indigenous religions, is still deeply rooted in Indonesian soil. With this socio-cultural background, Indonesian Islam has developed with the influence of local traditions. We see several Islamic rituals and practices that seem to have been "Indonesianized". Yet, this localized version of Islam is by no means favoured by more religiously strict Islamic groups. In 2015, Nahdlatul Ulama, the largest Islamic organization, launched the so-called Islam Nusantara movement, which upholds the essence of local culture in Islam. This newly-emerged religious movement also presents a profound question in relation to the authenticity of religion, that is, whether religions are able to maintain the "original" rituals and practices without historical,  geographical and regional influences. We will explore the development of the Islam Nusantara movement with this question in mind.

Botanic gardens, with their large holdings of living plants collected from around the world, are important guardians of plant biodiversity, but acquiring and curating these genetic resources is enormously expensive. For these reasons it is crucial that botanic gardens document and curate their collections in order to gain the greatest benefit from the plants in their care. Great priority is given to making detailed field notes and the process of documentation is often continued during the plants formative years when being propagated. However, for the large majority of plants this process often stops once the material is planted in its final garden location. The Data Capture Project at the Royal Botanic Garden Edinburgh is an attempt to document specific aspects of the plant collections so that the information captured can be of use to the research community even after the plants have died.
