Huge amounts of food waste exist in the consumption stage in developed countries. The waste can be converted into safe, nutritious, and value-added livestock feeds. ReFeed can be a game changer, simultaneously addressing multiple challenges such as food security, resource and environmental sustainability, and climate change. This is related to SDG's 2, 12, 13 and 14.
This paper explores the impact of mobile phones on gender equality and nutrition in Uganda. Using panel data from rural Ugandan smallholder farmers, the researchers analysed the social welfare effects of mobile phones. A positive connection is found between increasing female mobile phone use and improvement in nutrition, relating to SDG 2 and SDG 5 and where women have access to and use a mobile phone the impact was greater.

Contributing to SDG 1 and SDG 2, this paper shows that despite progress in reducing extreme poverty, little progress has been made in reducing the number of people living on between $1.25 and $2 a day and it provides updated estimates of rural and urban poverty for regions throughout the developing world. Social protection programmes are a key way for governments to support the poor. Secondly, agricultural input subsidies are a key government tool for boosting agricultural production, especially that of smallholder farmers. This paper is one of the first to examine both social protection and agricultural input subsidies in alleviating poverty.
Addressing hunger and malnutrition (goal 2) is key to advancing goal 3. This review and meta-analysis provides national, regional, and global estimates of lactose malabsorption, which can guide identification of likely causes of gastrointestinal symptoms and their optimal management, and also guide policy—eg, when choosing food for provision during famine outbreaks.
Advancing SDGs 2 and 15, this article examined biochar and biochar-compost in improving soil quality and crop types.
This paper examines the trends in famine over the last 150 years, with particular attention to the fusion of famine with forcible mass starvation. It identifies four main historic periods of famines, namely: the zenith of European colonialism; the extended World War; post-colonial totalitarianism; and post-Cold War humanitarian emergencies; and asks whether we may be entering a fifth period in which famines return in new guises. The paper explores structural causes of famine vulnerability, the overlapping but distinct causes of food crises and excess mortality in those crises, and the proximate triggers of famine. While noting that almost all famines have multiple causes, with no individual factor either necessary or sufficient, the paper focuses on the growing significance of political decision and military tactics in creating famine. It is an important review of the causes related to hunger and therefore to help advance SDG 2.
Bangladesh is one of the world's most vulnerable countries to climate change. This study combines environmental and human elements to assess socio-environmental outcomes. It examines the implications of climate change on poor communities dependent on fishing for their livelihoods, exploring the interconnectedness of SDG's 1,2, 14 and how they will be impacted by SDG 13.
This study makes important links between SDG 2, SDG 5 and SDG 13 through its examination of how husbands and wives within the same household perceive climate risks and use group-based approaches as coping strategies. The findings indicate that options for adapting to climate change closely interplay with husbands' and wives' roles and responsibilities, social norms, risk perceptions and access to resources. A higher percentage of wives were found to adopt crop-related strategies, whereas husbands employ livestock- and agroforestry-related strategies.
This comprehensive study examines the links between SDG 2 zero hunger and SDG 4 quality education by examining the impacts of parental education on child nutrition. It covers more than 350,000 preschool children from 56 developing countries and shows that impacts are larger for mothers and for secondary education than primary. It speculates that education might have more impact on the nutritional status of the next generation if school curricula focused on directly improving health and nutritional knowledge of future parents.
Focussing on SDGs 2 (Zero Hunger), 5 (Gender Equality) and 12 (Responsible Consumption and Production), this Elsevier Atlas Award winning article contributes to current discussions on the effective pathways to develop smallholder agriculture, enhance gender equity and enhance food security and rural livelihoods in the dry areas of the temperate world.
