“…Food waste recovery and redistribution initiatives are sustainable, usually local bottom-up [25], practices in supply food chain that provide consumers with otherwise wasted food [9]. We found that these local practices, which very often combine the aims of providing food for people in need while reducing the environmental impact of binning perfectly edible food [26,27], can be found worldwide in a large range of sizes, types of management and redistribution (Table S1 available with identification of all organizations found online).…”

The Contribution of Up-Cycled Food Waste to a Balanced Diet of Low-Income Households

This paper focuses on the contribution of an upcycling food organization to a balanced diet, which rescues and redistributes fresh or freshly cooked food to low-income households. To determine the nutritional balance of food hampers provided by our case study organization, according to the Portuguese food guidelines, we have weighed all items of food hampers in three weighing rounds over a period of four months. The results suggest that upcycled foods can contribute to a more balanced diet in terms of “Potato, Cereal and Cereal Products”, “Vegetables”, “Meat, Fish, Seafood and Eggs” and “Fruits”, both according to the Portuguese Food Wheel and compared to that of the general Portuguese population. The novelty of this study is the evaluation of the contribution to the balanced diet of the population in a vulnerable situation, of perishable foods such as freshly cooked, in traditional restaurants, cafes, bakeries, and hotels, or is naturally fresh (fruit and vegetables food aid services) up-cycled by a food aid organization.

“…Last but not least, a review on 'Limiting food waste via grassroots initiatives as a potential for climate change mitigation: a systematic review' focuses on the role of grassroots initiatives in reducing food waste and thereby mitigating climate change (Mariam et al 2020). From a quantitative perspective, the study found that grassroots initiatives have the potential to reduce GHG emissions by 4.3%-8.2% of the food sector's emissions.…”

It is now well established that the demand side can contribute substantially to climate change mitigation thus increasing the solution space. The recent IPCC synthesis report for the first time explicitly reflected this class of solutions. Here, we provide an overview of an unique set of 22 review papers published in the focus issue of Environmental Research Letters. We also extract a key set of insights, ranging from the varied but rapidly evolving literature to demand-side mitigation potential, relevance for well-being, and consistent categorization of options across end-use sectors. We find that demand-side approaches to climate change mitigation supplement exclusively technology-focused supply side solutions and, in many cases, comprise system-wide effect contributing to well-being and planetary stability. Review studies cover macro-economics, well-being, and sustainable development goals on the metric side, and investigate consumption-based individual options, urban strategies, transport, building, and food sector potentials, but also the role of the circular economy, material efficiency, and digitalization. Demand-side measures can be categorized into avoid, shift, and improve approaches. Several additional reviews systematically investigate psychological and social approaches and initiatives to foster climate change mitigation. We finally outline important gaps and questions to be tackled in the coming years.

“…The government cannot lead all changes, nor should it be expected to do so. Community-based initiatives are critical in ensuring that system transformation takes place-from reducing consumption to changing disposal habits (Grabs et al, 2016;Mariam et al, 2020). Within Qatar, there are a number of such initiatives, such as efforts seeking to reduce plastic consumption as well as efforts to support companies to transition away from plastic usage.…”

This chapter is an attempt to track the evolution of the solid waste management (SWM) system in Qatar including its recent technological leap of establishing Mesaieed's integrated waste management facility. A variety of factors that have contributed in shaping the sector are determined covering external and internal, hard and soft, ones in the political, economic, and social contexts. Despite the strides, the Qatari SWM sector has witnessed under the aspiration of the sustainability-conscious Qatar National Vision 2030 and its emanated two National Development Strategies (2011-2022) underperformance and lack of vertical and horizontal synchronization among stockholders are evident. A zero-waste framework is suggested as an ideal vehicle for upgrading the current waste management system into a circular one, backed with legislative, financial, social, and knowledge-based instruments. Successful local campus-scale zero-waste management models, like Qatar University, provide blueprints that can be amplified through a nexus systems thinking approach applied on an inclusive Energy-Water-Food-Waste urban setup.
