The present research represents an approach toward the recycling of extractive waste inspired by circular economy and sustainability that is developed in accordance with Goal 12 of the United Nations 2030 Agenda for Sustainable Development Goals. A new procedure for the recovery of REEs from fluorite–barite–galena ores with calcite gangue from the Silius mine (Sardinia, Italy) is presented. The considered samples are waste materials of Silius mineralization, collected in the old processing plant of Assemini (near Cagliari). In this orebody, REE minerals consist of prevailing synchysite (a REE-bearing fluorocarbonate) and subordinate xenotime-Y (a Y-bearing phosphate). REE fluorocarbonates are extracted using 50% K2CO3 as the leaching solution, at 100 °C. Using a solution (mL)/sample (g) ratio of 25, about 10% of the total REE content of the considered sample is extracted within 1 h. At the laboratory scale, such alkaline leaching of REE from the waste materials allows the recovery of the CO2 produced as K2CO3 from concentrated KOH, in accordance with a circular flow. Further work is ongoing to scale up the process into a pilot plant, to prove that the method developed within this research can be economically feasible, socially suitable, and environmentally respectful.

AbstractBefore the world was impacted by COVID-19, progress towards the 2030 UN Sustainable Development Goals (SDGs) was already uneven, and a more focused attention was needed in most SDGs’ target areas. The pandemic abruptly disrupted plans and efforts towards urban transition, in some cases reverting decades of progress. The concept of resilience changed in 2020 and having to face severe health issues combined with increased socio-economic challenges in a climate change scenario, cities must urgently explore on how best to combine environmental goals with economic recovery and social justice, modifying on-going plans and initiatives, while re-arranging priorities. Acknowledging the impact that the pandemic will produce, for the years to come, on processes and initiatives towards a regenerative economy, this contribution describes most recent strategies aimed at urban transition in Europe, and critically discusses available options with respect to implementation and funding, within the framework of selected UN SDGs. Our conclusions challenge the ability of our modern society to put in practice the needed urgent actions, and call for a paradigm shift to prepare Europe to deal with climate disruptions, activate transition to a healthy and prosperous future within the planetary boundaries, and scale up solutions that will trigger transformations for the benefit of people and the environment.

Evidence on early achievements, challenges and opportunities would help low-income and middle-income countries (LMICs) accelerate implementation of health and health-related sustainable development goals (HHSDGs). A series of country-specific and multicountry consultative meetings were conducted during 2018–2019 that involved 15 countries across five regions to determine the status of implementation of HHSDGs. Almost 120 representatives from health and non-health sectors participated. The assessment relied on a multidomain analytical framework drawing on existing public health policy frameworks. During the first 5 years of the sustainable development goals (SDGs) era, participating LMICs from South and Central Asia, East Africa and Latin America demonstrated growing political commitment to HHSDGs, with augmentation of multisectoral institutional arrangements, strengthening of monitoring systems and engagement of development partners. On the other hand, there has been limited involvement of civic society representatives and academia, relatively few capacity development initiatives were in place, a well-crafted communication strategy was missing, and there is limited evidence of additional domestic financing for implementing HHSDGs. While the momentum towards universal health coverage is notable, explicit linkages with non-health SDGs and integrated multisectoral implementation strategies are lacking. The study offers messages to LMICs that would allow for a full decade of accelerated implementation of HHSDGs, and points to the need for more implementation research in each domain and for testing interventions that are likely to work before scale-up.

While several studies have examined the impact of the Covid-19 pandemic on smallholder rural farmers and possible efforts to scale up their livelihood and food security, the role of consumers’ buying orientation in addressing farmers’ vulnerability in the post-pandemic era has not been explored. The paper, therefore, aims to propose and conceptualize humane buying orientation, and further explore its role in attenuating smallholder rural farmers’ vulnerability in the new normal. The qualitative design approach has been employed in two different studies. Collected data were analyzed using the SPSS 23.0 and following the interpretative phenomenological analysis. Findings validate humane buying as an altruistic orientation that will contribute to lessening the vulnerability of smallholder rural farmers in the post-pandemic era. It also shows that an enlarged-stakeholders’ (government, international agencies, corporate bodies, institutions, privileged individuals/consumers, religious organizations, etc.) effort that is rooted in morality and empathy, is required to successfully tackle the vulnerability of smallholder rural farmers, especially in developing countries such as Nigeria. The study is the first to propose, conceptualize and validate humane buying as a post-Covid-19 orientation that is capable of attenuating the vulnerability of smallholder rural farmers which has been worsened by the pandemic. The paper contributes to the understanding of emerging strategic actions required for the attainment of the United Nation’s sustainable development goals - ending poverty and hunger by 2030, and how consumers can play a key role.

Over just a six-year period from 2005-2011, five aid effectiveness initiatives were launched: the Paris Declaration on Aid Effectiveness (2005), the International Health Partnership plus (2007), the Accra Agenda for Action (2008), the Busan Partnership for Effective Cooperation (2011), and the Global Partnership for Effective Development Cooperation (GPEDC) (2011). More recently, in 2015, the Addis Ababa Action Agenda (AAAA) was signed at the third international conference on financing for development and the Universal Health Coverage (UHC) 2030 Global Compact was signed in 2017. Both documents espouse principles of aid effectiveness and would most likely guide financing decisions in the Sustainable Development Goals (SDG) era. This is therefore a good moment to assess whether the aid effectiveness agenda made a difference in development and its relevance in the SDG era.

Responding to the substantial finance gap for achieving Sustainable Development Goals 6.1 and 6.2, the water and sanitation sector has mobilized to launch new blended finance vehicles with increasing frequency. The sustainability and scale-up of financial solutions is intended to support increased access to unserved, marginalized populations. However, without addressing foundational issues in the sector, any finance mechanism, whether public, private or blended, will be a short-term, band-aid solution and the sector will continue the cycle of dependency on external assistance. This paper presents the results of a collaborative effort of; the IRC water, sanitation and hygiene sector (WASH); and the World Bank Water Global Practice. Drawing from the latest research on effective public financial management and based on evidence from the countries where these organizations work, the paper demonstrates that sustainable success in mobilising finance on a large scale is dependent on a reasonable level of performance across 10 foundational areas. The paper presents evidence on the 10 foundational areas and discusses why other aspects of finance and governance, while necessary, are not sufficient. Better coordination amongst all development partners and governments, including a collective commitment to and prioritization of working on these foundational issues, is a necessary first step.

Abstract. Economic changes in the context of globalization have left adolescents from Latin American contexts with few opportunities to make satisfactory transitions into adulthood. Recent studies indicate that there is a protracted period between the end of schooling and entering into formal working activities. While in this “limbo,” illicit activities, such as drug trafficking may emerge as an alternative for young people to ensure their social participation. This article aims to deepen the understanding of Brazilian youth’s involvement in drug trafficking and its intersection with their schooling, work, and aspirations, connecting with Sustainable Development Goals (SDGs) 4 and 16 as proposed in the 2030 Agenda for Sustainable Development adopted by the United Nations in 2015 .
