Space for the Sustainable Development Goals: mapping the contributions of space-based projects and technologies to the achievement of the 2030 Agenda for Sustainable Development

Progress towards the achievement of the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda for Sustainable Development in many ways presupposes the utilisation of science, technology and innovation. Many sustainability-oriented projects across industries make use of space-based technologies and services to contribute to the Goals. Among others, satellite-based Earth observation, positioning, navigation and communication services are used in an array of sectors ranging from monitoring environmental conditions and changes to supporting search and rescue missions. In order to illustrate contributions to the SDGs, space agencies and other institutions have aligned their projects to the SDG framework. This study attempts a more holistic, aggregate mapping of such alignments to gauge which SDGs benefit the most and from space-based projects and technologies, as opposed to those benefiting the least. The results demonstrate that the number of contributing projects varies significantly across the Goal spectrum, as does the share of the various technologies involved, with particular focus on industrial development, hunger elimination, and improved healthcare. Nevertheless, the range of application of space-based technologies is wide and highlights the relevance of space to support the transition towards a sustainable future.

The sustainability of reforesting landscapes with exotic species: a case study of eucalypts in Ethiopia

Eucalypt reforestation has been a common feature of many countries, especially in the developing countries, such as Ethiopia. Farmers in Ethiopia plant large numbers of eucalypts on small areas of land and manage them to yield a variety of products, including leaves and small branches for fuelwood, and poles and posts for house building and other farm uses. Many people in Ethiopia are dependent on eucalypts as a source of fuel and house building material. The use of trees, especially eucalypts, as a living bank account, to be harvested when there is a need for cash, is widespread. This being the reality, the arguments for and against planting eucalypts in Ethiopia has been mounting from time to time, especially associated with water use, soil fertility, soil erosion, allelopathic effects, understory vegetation and plant diversity as well as wild animals. The paradox of reforestation using eucalypts results, mostly, from inappropriate species-site matching and poor management rather than the inherent biological characteristics of the species. Therefore, the debate on eucalypts under the pretext of concern for indigenous species and natural forests should shift to how both plantations established using eucalypts and indigenous species as well as natural forests can help in the enhancement of the socio-economic development and environmental conservation of countries, such as Ethiopia. Despite the claimed negative impacts of eucalypts, farmers in Ethiopia have utilized their traditional knowledge and experience in establishing and managing eucalypt stands. In addition, the available reports in Ethiopia are in favour of planting eucalypts since the authors acknowledge that: (i) the negative impacts can be minimized provided that the choice of species and site as well as the management of the stands are appropriate, (ii) the benefit derived can offset the losses that can occur from such plantations, (iii) no other species seems to replace them to bridge the ever-widening gap between demand and supply of wood and (iv) the profit derived from eucalypt plantations is considerably higher than cultivating crops. However, the choice of eucalypt species should be based on many criteria, for example maximum wood production, ecological sustainability, marketability of the planted species and usefulness of the species to the local populations. All these criteria involve not only a choice of species planted, but also a choice of plantation management methods from initial planting to final cutting of the trees. Careful selection of appropriate species and matching them with appropriate sites must be taken as prerequisite, and the right management practices should be employed.

Plastics: are they part of the zero-waste agenda or the toxic-waste agenda?

Background Plastics were considered as a magical material owing to their strong, non-degradable and versatile characteristics. After five decades of mass application, plastics’ property of non-biodegradability has become one of the key concerns for scientists, civil society and government owing to the pollution and damage that plastics cause to our environment. Globally we have generated 8.3bn tonnes of plastics since 1950s and around 9% has been recycled, 12% incinerated and the remaining 79% of the plastics has ended up in the environment. The core question is, should this waste be minimised through the zero-waste agenda or banned through the toxic-waste agenda? Results The study analyses the zero plastic waste agenda and the toxic plastic waste agenda. It analyses zero-waste practices at different levels including family to community, industry and city levels. In addition, the study investigates the need to phase out toxic plastics. The study identified the need for both approaches. As plastics promote the throwaway living which is responsible for generating undesirable waste, it should be tackled through better design principles and sustainable consumption practices for the short-term agenda. The study proposes a strategic zero plastic waste framework for moving towards a zero plastic waste society. At the same time, there is a need to identify those plastics that are leading to serious and toxic impacts through micro-particles that necessitate them to be phased out more quickly through transitioning to bio-plastics. Conclusions Both zero plastic and zero toxic agendas are urgently needed. The study concludes that at least three things in the short term need to be implemented simultaneously to achieve a zero plastic waste society. Firstly, through zero-waste design - to eliminate creating any unnecessary plastic waste through closed-loop design thinking. Secondly, through responsible and collaborative consumption - to avoid and reduce generating avoidable plastic waste. Finally, through zero-waste management - to prioritise the value, retain the wasted materials and recover all resources. The study also establishes that a new long-term agenda needs to be created to identify those plastics that must be phased out owing to their toxicity. Consequently, the study suggests a process to achieve it in line with the transition to the post fossil-fuel era through United Nations initiatives as a joint action of the Paris Agreement and the Basel Convention.

From space back to Earth: supporting sustainable development with spaceflight technologies

For the past decades spaceflight has been a driver for technology development in various fields, e.g. generation of electrical power, and computers. Human spaceflight missions, require resources typically scarce (e.g. oxygen) and are usually transferred along with the crew to the respective mission target. Future long-term missions aim beyond Low Earth Orbit (i.e. Moon and Mars), necessitating advances especially in closed-loop life-support systems to guarantee mission autonomy. This requires careful handling of the resources, i.e. minimizing waste and where possible harvesting resources in situ. Similarly, on Earth a sustainable way of life requires careful handling of resources. This paper discusses how both pathways relate to each other and how “settling” Earth sustainably and settling in any space location do not differ in their basic paradigms. It is shown how spaceflight has had an impact on sustainability in the past, which technologies are developed for human spaceflight and how they can be applied on Earth to improve sustainability. Finally, a research infrastructure is presented, which can conduct research on closed-loop technologies, immediately benefiting space and terrestrial applications. This incubator is divided into separate functional modules, which allow testing of technology components. These components can be exchanged to test various permutations of technologies. It is recommended to exploit synergy effects between activities concerning human spaceflight and sustainability by intertwining and coordinating these actions. The technological improvement driven by spaceflight programs can be used to drive sustainability as well.

“Stewards of the future: accompanying the rising tide of young voices by setting youth-inclusive research agendas in sustainability research”

Background From the worldwide youth-led climate strikes of 2018–2019 to the student-initiated austerity protests in Chile in 2019, it is undeniable that young people have been protagonists in pressuring for social change towards greater sustainability in recent years. This piece reflects on youth as agents of social-ecological change, and what researchers can learn from the rise in youth-led social movements demanding action in the face of global sustainability challenges. The study of sustainability problems like climate change and biodiversity loss, intrinsically requires consideration of inter-generational equity. However, despite 50% of the global population being under 30 years old, youth are often not included explicitly as actors in environmental social sciences and sustainability-related research. Here we discuss why explicitly considering young people as distinct actors during the research process is important, as it allows researchers to engage in just and inclusive work whilst at the same time accounting for important agents of change in complex social-ecological systems. Results As a framework for our inquiry we present the themes which emerged during a series of international meetings and forums on sustainability challenges and youth in 2019, a year characterized by world-wide youth mobilization. Our briefing spans the United Nations Youth 2019 Climate Action Summit, the post-2020 meetings organized by the youth branch of the Convention of Biological Diversity (CBD), the UNESCO Man and Biosphere Youth forums and the results from the Global Shapers Survey of the World Economic Forum. Conclusions We argue that if researchers wish to facilitate youth-inclusive evidence-based decision making, research agendas must address knowledge gaps highlighted by institutional efforts to incorporate youth concerns within global sustainability policy, a recommendation that is even more relevant in the light of the COVID-19 crisis. We draw on the themes which emerged in our analysis of international youth meetings to provide recommendations for research agendas which account both for young actors as both passive and active components of social-ecological change and we propose a more inclusive and holistic study of coupled natural-human systems.

Shaping of sustainable citizenship among young people of Kulhudhuffushi, Maldives and Hamilton, New Zealand: context, conditions and experiences

Background Engagement of young people is essential for achieving sustainable outcomes both locally and in the global context. Democratic processes appear to be the most facilitative mechanism to hold governments to account with governments becoming more receptive to pro-environmental policies when there is input from citizens to do so. While there is concern about a general lack of participation in traditional forms of political processes, particularly among young people, there are those who are carving a space for themselves as active citizens within a system that is often times contradictory to their lives. In this context, this paper looks at the lived experiences of a small sample of active young people in Kulhudhuffushi island of Maldives and Hamilton, New Zealand to examine the contexts and conditions that lead to and sustain these forms of sustainable citizenship. Results In-depth interviews conducted with young people in both locations found similarities within both groups in terms of motivating factors, knowledge and support networks, lifestyle practices, and conceptualisations of citizenship. Early exposure to natural environments, role models and participation in actions and networks helped to create active citizenship, while lack of conducive spaces and cultural attitudes impeded activism. Conclusion The results show that providing opportunities for early interactions with nature, and participation in actions and activist networks is vital for fostering and sustaining active citizenship. Additionally local and national groups and institutions need to facilitate spaces conducive for organising and alternative narratives, as well as promoting a counter culture to the current carbon heavy system. The findings contribute to literature on listening to youth voices in environmental and climate activism.

Global crop waste burning – micro-biochar; how a small community development organization learned experientially to address a huge problem one tiny field at a time

The world’s 2.5 billion poorest people - small farmers living at the far fringe of the developing world – and their billion or so slightly better off neighbors burn 10.5 billion metric tonnes (tonnes) of crop waste annually. Smoke from their fires reddens the sun, closes airports, shuts schools and governments – and kills millions of people (World Health Organization (WHO). who.int/health-topics/air-pollution#tab=tab_1). Their fires release 16.6 billion tonnes of CO2, and emit 9.8 billion tonnes CO2e, 1.1 billion tonnes of smog precursors and 66 million tonnes of PM2.5. (Akagi et al., Atmospheric Chem Physics 4039-4071, 2011; Environmental Protection Agency, epa.gov/ghgemissions/understanding-global-warming-potentials; Food and Agriculture Organization, FAOSTAT, http://www.fao.org/faostat/en/#data) [See Attachments 1–3. For details of the Attachments, please see the section below entitled “Availability of data and materials.”]. No one yet has stopped the burning. Seminars, health warnings, bans, threats, jailings, shootings – nothing has worked, because not one has offered farmers a better alternative. This is the story of how Warm Heart, a small, community development NGO, learned enough about small farmers’ plight to collaborate with them to develop the technology, training and social organization to mobilize villages to form biochar social enterprises. These make it profitable for farmers to convert crop waste into biochar, reducing CO2e, smog precursor and PM2.5 emissions, improving health and generating new local income – in short, to address the big three SDGs (1, 2 and 3) from the bottom.Warm Heart, however, wanted more; it wanted a system so appealing that it would spread by imitation and not require outside intervention. Based on what it has learned, Warm Heart wants to teach others that the knowledge to stop the smoke and improve the quality of one’s life does not require outside experts and lots of money. It wants to teach that anyone can learn to create a more sustainable world by themselves.This article traces the experiential learning process by which Warm Heart and its partners achieved their goals and shares Warm Heart’s open source solution. It serves four purposes. The article closely explores an experiential learning process. It details the underlying logic, workings and consequences of crop waste burning in the developing world. It demonstrates the application of this knowledge to the development of a sustainable – even profitable – solution to this global problem that does not require costly outside intervention but can be undertaken by local communities and small NGOs anywhere. Finally, it models how local communities, small NGOs and social investors can turn this global problem into a profitable business opportunity.

Young people and environmental affordances in urban sustainable development: insights into transport and green and public space in seven cities

Background Cities are at the fore of sustainability challenges of the twenty-first century, and many, particularly in Asia and Africa, are predominantly youthful spaces. Understanding young people’s experiences in urban environments is therefore important as we strive to achieve both the Sustainable Development Goals and the Paris Agreement. Two amenities identified in the urban Sustainable Development Goal 11, transport and public and green space, are specifically recognised as applying to youth. Yet, there is little analysis that explicitly considers how youth experience these amenities across the Global North and South, and no current measures for understanding progress in youth experiences of green space and transport. Results This paper provides a comparative analysis of young people’s experiences with local transport and green space in seven diverse urban communities (Christchurch, New Zealand; Dhaka, Bangladesh; Lambeth/London, UK; Makhanda, South Africa; New Delhi, India; São Paulo, Brazil; and Yokohama, Japan). Our study contributes to a growing body of literature that seeks to listen to child and youth perspectives to understand their environmental experiences. We examine the ‘affordances’ young residents aged 12 to 24 years currently associate with green space and transport amenities. Affordances are defined here as the inter-relationships between what a local environment offers young people and their perceptions and actions. Drawing on focus groups and interviews conducted with 332 young people, we identify five affordances young people associate in relation to transport and public space across these diverse urban settings: (1) social inclusion and belonging; (2) autonomy; (3) physical comfort and security; (4) relaxation and reflection; and (5) health and fitness. Conclusions The paper contributes to growing interdisciplinary research interest in measuring affordances as a way to advance the Sustainable Development Goals in an urban context. In providing a comparative account of young people’s experiences across diverse contexts, our discussion highlights how affordances in relation to transport or public and green space can help understand the multiple interconnections between the well-being of young people and sustainability. In particular, we argue that it is not merely the provision of transport or public and green space that matters, but the nuanced meaning of places and experiences as understood by local communities that needs to be recognised if we are to better support urban youth wellbeing and advance sustainable development goals.

‘They don’t quite understand the importance of what we’re doing today’: the young people’s climate strikes as subaltern activism

Background Youth-led movements like #FridaysforFuture and the school strikes for climate (henceforth referred to as the climate strikes) are leading calls for action on climate change worldwide. This paper reports on a thematic analysis of protest signs, and interviews with young climate strikers, at a climate strike in Manchester, UK, in 2019. Results This paper explores the ways in which dominant, adult-centred frameworks for conceptualizing young people’s environmental activism tend to obscure the complexities of the climate strike movement. In contrast, this study examines the complex political activism of climate strikers as a ‘subaltern group’, who take political action in a wider context of intersecting categories of oppression and marginalization – including youth as a category of marginalization – and in the historical context of environmental racism, the enduring legacies of colonialism, and global inequality during contemporary capitalism. Conclusions The article develops a theoretical model for future research, based on a model of two constraining frames that limit analysis of the climate strikes in particular and young people’s environmental activism in general. This paper contributes to a step change in methods for the study of this remarkable movement in a global context.

Teen activism leads to local laws banning single-use plastics: a two-year experiential learning journey

This paper recounts the two-year journey of an eight-member public Massachusetts high school environmental club that set out to decrease their local community’s consumption of single-use plastics. In the academic years 2016–2018, launched by a presentation by co-author Dr. Kara Lavender Law, the students wrestled with the global problem of plastic environmental debris within their local sphere of influence. They petitioned town government to regulate against local merchants’ dispensing thin-film plastic bags or selling single-use plastic water bottles < 1 L in size. The journey called upon them to participate in the democratic process, and through it to inform the citizenry, entertain opposing viewpoints, counter strident opposition with facts, enlist allies, and build broad consensus. After a two-year process, the project arrived at a successful result. They learned through experience that with tenacity, they could make democracy work for their ethical ideals.
