A necessary extension of the concept of Resource Recovery and Reuse with an even higher priority is the prevention and reduction of waste. One concern, in particular, is food waste, which constitutes the largest share of human waste. Target 12.3 of the United Nations Sustainable Development Goals (SDGs) is to ‘halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses, by 2030’. For this report, over 400 businesses were analyzed to identify common approaches and business models to address the food waste challenge. The business models are presented under seven categories – measurement, redistribution, resell, value addition, responsible waste collection, resource recovery, and recycling – with a special focus on their application potential to the Global South.

The nexus approach offers an important heuristic tool for the sustainable management of resources by considering the links among different sectors. The food-energy-water (FEW) nexus corresponds to links among the three of seventeen United Nations Sustainable Development Goals (SDGs), namely SDG2 (No Hungry), SDG6 (Clean Water and Sanitation), and SDG7 (Affordable and Clean Energy), and their interlinkages have a direct or indirect impact on other SDGs. However, there is still a lack of a systematic and quantitative analysis of how the nexus approach could promote achieving SDGs. Here, taking China as a case, we built an expanded FEW nexus framework from the lens of SDGs, which consists of six sectors, including food (SDG2), water (SDG6), energy (SDG7), economic (SDG8), consumption and production (SDG12), and forest (SDG15). We quantified the two-way interactions between the six sectors by the panel vector autoregressive (PVAR) model. Results indicate that sectors exhibit different response characteristics (positive or negative) in their interactions, and these responses could change over time. These results imply that changing the priorities of actions may be an effective measure to transform trade-offs into synergies. Moreover, the contribution of different sectors to each other varies considerably, with economic growth (SDG8) generally having a higher impact on changes in the FEW nexus than consumption and production patterns (SDG12). Our research suggests that strengthening the quantitative assessment of two-way interactions among the FEW nexus has crucial implications for leveraging nexus approaches effectively to achieve sustainable development for all.

Introduction: Intercropping cereals with legumes can intensify rainfed cereal monocropping for improved household food and nutritional security. However, there is scant literature confirming the associated nutritional benefits.
Methodology: A systematic review and meta-analysis of nutritional water productivity (NWP) and nutrient contribution (NC) of selected cereal-legume intercrop systems was conducted through literature searches in Scopus, Web of Science and ScienceDirect databases. After the assessment, only nine articles written in English that were field experiments comprising grain cereal and legume intercrop systems were retained. Using the R statistical software (version 3.6.0), paired t-tests were used to determine if differences existed between the intercrop system and the corresponding cereal monocrop for yield (Y), water productivity (WP), NC, and NWP.
Results: The intercropped cereal or legume yield was 10 to 35% lower than that for the corresponding monocrop system. In most instances, intercropping cereals with legumes improved NY, NWP, and NC due to their added nutrients. Substantial improvements were observed for calcium (Ca), where NY, NWP, and NC improved by 658, 82, and 256%, respectively.
Discussion: Results showed that cereal-legume intercrop systems could improve nutrient yield in water-limited environments. Promoting cereal legume intercrops that feature nutrient-dense legume component crops could contribute toward addressing the SDGs of Zero Hunger (SDG 3), Good Health and Well-3 (SDG 2) and Responsible consumption and production (SDG 12).

Sustainable Development Goal (SDG) 12.3 of the UN 2030 Agenda calls for halving per capita global food waste (FW) from retail to households. Food waste (FW) prevention and reduction play a major role in ensuring the sustainability of food systems as well as effective Solid Waste Management (SWM). A coherent, coordinated, and complementary approach to quantification causes identification, and scaling up feasible solutions is necessary. Awareness-raising and capacity development for food supply chain actors, the public sector, and civil society organizations is required for successful interventions. The Project Innovative approaches to reduce, recycle and reuse FW in urban Sri Lanka was implemented under the oversight of the Ministry of Urban Development, and Housing in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the International Water Management Institute (IWMI) from June 2019 to August 2021. The project produced a series of reports and papers including FAO and IWMI (2021a), FAO and IWMI (2021b), FAO and IWMI (2021c), and FAO and IWMI (2021d) that were used in the awareness creation and capacity development programmes. The major output of the Project was to facilitate knowledge development for and drafting of the Urban Roadmap on FW Prevention, Reduction, Management in Sri Lanka, that includes a comprehensive Action Plan with Monitoring and Evaluation criteria. The objective of this report is to summarize the proceedings of the consultations and sensitization sessions conducted from June 2019 to June 2021.

Mapping stakeholders and their potential roles for prevention and reduction of food waste (FW) supports a coherent, coordinated and complementary approach to quantification, causes identification and scaling up of feasible solutions for significant returns on investment. State and nonstate stakeholders were mapped in selected municipalities: Colombo metropolitan area (Colombo, Sri Jayewardenepura-Kotte, Negombo, Kaduwela and Moratuwa municipal council areas), Jaffna, Kandy, Batticoloa, Kurunegala and Galle. Stakeholders were grouped into four clusters: producers, enterprises/food business operators, private/public/civil society organizations and households. The stakeholders’ maps guided sensitization and capacity-building sessions whose conclusions fed into the preparation of the National Roadmap on Urban Food Waste Prevention and Reduction for Households, Food services, Retailers and Wholesalers launched on 17 August 2021. According to the analysis, the institutions working on food and/or (bio-)waste can be divided into governmental, semi-governmental, private, and non-governmental. Food safety, quality control and waste management in Sri Lanka is under the umbrella of the central government, provincial council (PC) and local authorities(LAs) that cover governance (e.g. policies and regulations), production, trade, input supply, services, welfare support and research. However, duties and responsibilities are, sometimes, crosscutting and interrelated with overlaps that can lead to poor coordination. An array of institutions at central and provincial levels are engaged to strengthen the food production sector in Sri Lanka. The existing inter-institutional coordination mechanism could be improved. The coordination for knowledge generation and dissemination between national and provincial systems should be strengthened. The report was produced for the project Innovative approaches to reduce, recycle and reuse FW in urban Sri Lanka that was implemented under the oversight of the Ministry of Urban Development and Housing, in collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the International Water Management Institute (IWMI) from June 2019 to August 2021.

By 2050, over 40% of the global population could face severe water stress. The 2030 Agenda explicitly integrates water resources, supply, and sanitation, emphasizing sustainability for present and future generations. Non-revenue water (NRW) creates a barrier to sustainability through energy, water loss, and money not collected through water bills. However, NRW is well recognized by water service providers, and a comprehensive solution is lacking. Addressing NRW is vital to sustainable operations and achieving the Sustainable Development Goals (SDGs). This desk literature review investigates NRW's links with SDGs, highlighting global and local impacts, flameworking interconnections, and revealing economic, social, and environmental consequences. The study revealed that NRW not only aligns with various SDGs, particularly SDG 6 and SDG 13, but also has synergies with other goals related to energy and sustainable consumption. Reducing NRW can achieve more sustainable and resilient water systems, and contribute to the broader SDG. The cost of NRW extends beyond the financial implications for water utilities. It also encompasses the economic impacts on industries and businesses, which impacts exceeded water productivity, increased operational costs, and economic development constraints.
