Irrigation water has been identified as a source of contamination in recent produce-linked outbreaks. With seasonal variations in climate changes, factors such as drought have a profound effect on agriculture. Recent studies have analyzed various water sources to establish microbial and chemical profiles to determine if they are fit for use as irrigation water in fresh produce fields. This review focuses on the recent research done and current regulatory trends seen with respect to water reuse systems. Alternative irrigation sources are being applied to crops not for human consumption but need an extensive health-based assessment before they can be applied to food crops in the field. This paves the way for novel technologies such as computational modeling and simulation to thoroughly assess the risks associated with using nontraditional water sources for crops for human consumption.

Companies are responsible for reporting not only their own water practices but also those of their suppliers. An evaluation of the supply chain water information in the sustainability and integrated reports of 49 food, beverage and tobacco firms listed on the JSE (South Africa), ASX (Australia) and Dow Jones Sustainability Index (DJSI) exchanges, respectively, was conducted. It was found that the companies fall short in their disclosure of consumption of water-related supply chain information. The firms listed on the DJSI and JSE outperformed the Australian companies. This paper presents and applies a novel water disclosure index of supply chain information.

Land and water are vital resources for sustaining rural livelihoods and are critical for rural development as they form the basis of agriculture, the main economic activity for rural communities. Nevertheless, in most developing countries, land and water resources are unevenly distributed due to historical and socio-economic imbalances, hence the need for land reform policies to address these disparities. However, redistributing land without considering the interconnectedness of land and socio-ecological systems can compound existing food and water insecurity challenges. This study used a mixed research method, integrating both quantitative and qualitative data, to develop a framework to guide policy and decision-makers to formulate coherent strategies towards sustainable land redistribution programmes and achieve the desired outcomes. The approach was vital for integrating the broad and intricate interlinkages between water, land, and environmental resources. Therefore, the framework is based on transformative and circular models for informing strategic policy decisions towards sustainable land redistribution. The focus was on South Africa’s land redistribution plans and the implications on water and food security and rural development. The developed framework is designed to ensure the sustainability of agrarian reform and rural economic development. It is framed to address land and water accessibility inequalities, promote water and food security, and enhance rural development. A sustainable land redistribution increases the adaptive capacity of rural communities to climate change, enhances their resilience, and provides pathways towards Sustainable Development Goals (SDGs).

Abstract Background Inadequate food and water resources negatively affect child health and the efficiency of nutrition interventions. Methods We used data from the SHINE trial to investigate the associations of food insecurity (FI) and water insecurity (WI) on mothers’ implementation and maintenance of minimum infant dietary diversity (MIDD). We conducted factor analysis to identify and score dimensions of FI (poor access, household shocks, low availability & quality), and WI (poor access, poor quality and low reliability). MIDD implementation (n = 636) was adequate if infants aged 12 months (M12) ate ≥ four food groups. MIDD maintenance (n = 624) was categorized into four mutually exclusive groups: A (unmet MIDD at both M12 and M18), B (unmet MIDD at M12 only), C (unmet MIDD at M18 only), and D (met MIDD at both M12 and M18). We used multivariable-adjusted binary logistic and multinomial regressions to determine likelihood of MIDD implementation, and of belonging to MIDD maintenance groups A-C (poor maintenance groups), compared to group D, respectively. Results Low food availability & quality were negatively associated with implementation (OR = 0.81; 0.69, 0.97), and maintenance (ORB = 1.29; 1.07, 1.56). Poor water quality was positively associated with implementation (OR = 1.25; 1.08, 1.44), but inconsistently associated with maintenance, with higher odds of infants being in group C (OR = 1.39; 1.08, 1.79), and lower odds of being in group B (OR = 0.80; 0.66, 0.96). Conclusion Food security should be prioritized for adequate implementation and maintenance of infant diets during complementary feeding. The inconsistent findings with water quality indicate the need for further research on WI and infant feeding.

Under the double pressure of ecological vulnerability and economic development, natural resources and ecological environment have become the key constraints to the development of the Yellow River Basin (YRB). This paper proposed a theoretical framework for the relationship between water-energy-food (WEF) and poverty. An improved coupling coordination degree model and the geographical detector were used to evaluate the spatio-temporal coupling between WEF and poverty and its influencing factors in YRB. The results suggest that the levels of coupling coordination increase to different degrees in YRB and its provinces from 2000 to 2019, and the coupling types are characterized by pyramidal-shaped distribution. The regions of YRB are divided into four development types: water-driven type, energy-driven type, food-driven type, and economy-driven type. Spatially, a dominant factor zone is formed with a multi-polar core. Furthermore, some practical suggestions are put forward to promote the effective utilization of water resources and high-quality development according to specific regional situations in YRB. This study will promote coupling coordination and high-quality development in YRB, providing a reference for the coordination of the human-land relationship and regional sustainable development.

Understanding the status of water-energy-food (WEF) Nexus, oriented to the whole process of water extraction and deployment, water consumption for crop growth, and food production output, in irrigation systems is essential for food security and resources sustainability. Based on WEF Nexus quantification, combining traditional agricultural water-saving and water footprint theory, the sustainable development level (SDL) of water acquisition-transfer-consumption process for pumped irrigation systems was analyzed, using the principal component analysis (PCA) and taking the Lianshui Irrigation District (LID) in eastern China as a case study, in this paper. The driving mechanism of SDL for WEF Nexus was revealed by virtue of the partial least-squares regression (PLSR). Results showed that, annual SDL of the WEF Nexus in the pumped irrigation systems was 0.3 during the study period 2005–2019, mainly due to the low SDLₑ and SDLf, indicating that sustainability had been concerned. PRE and RRI were significant-positive factors, while CDI functioned as significant-negative driving factors on SDL of WEF Nexus. The measures adjusting crop planting structure, transforming irrigation and drainage mode, updating water pump equipment, and increasing agricultural investment contribute to the sustainability of WEF Nexus in the observed irrigation systems. Therefore, the sustainable management can be implemented according to the unique driving factors identification of WEF Nexus in pumped irrigation systems. The research is conducive to the management and program for irrigated agricultural systems under the changing circumstances.

Water is a major driver of food systems in arid and semi-arid countries. This paper explores the role of water in Egypt’s food system and the dilemma the country faces: raise food self-sufficiency by allocating freshwater resources from the Nile to food production, or rely on food imports from water-abundant regions worldwide. Using a food system analysis approach, the main drivers and outcomes in Egypt’s food system are described, followed by two examples of food system trade-offs where water plays an important role: wheat and chicken. The paper concludes with a reflection on the role of water in the food system and gives suggestions on how the role of water in the food system can be addressed systematically.

Safe and secure access to drinking water and sanitation are human rights that are vital to social, economic, and environmental wellbeing. While interpretations of these rights often focus on domestic water access – for example, whether someone has sufficient drinking water – there is increasing recognition that water for health, food security and nutrition, and basic livelihood needs are inextricably linked. A progressive approach to the human rights to water needs to consider interlinked priorities around food and livelihoods. | Non-PR | 1 Fostering Climate-Resilient and Sustainable Food Supply; IFPRI5 | EPTD
