In light of recent developments such as the COP21 Paris climate agreement, the UN adoption of the Sustainable Development Goals for 2030, and the Habitat III Conference, there is increasing recognition of the role of human settlements as key components of both global challenges and global solutions. "Urban sustainability" under various names has matured over the last three decades not only in planning and related fields, but also in wider professional and popular discourse. In this paper we trace a historical overview of urban sustainability theory and practice, and explain why urban sustainability planning and development currently face limited and inconsistent application. We show that this lack of public uptake is due in part to monitoring, assessment, and decision-support frameworks and tools that do not engage citizens and their governments in a shared "strong sustainability" analysis and/or vision. We argue that urban sustainability today clearly needs to embrace equity, inclusion, and other social considerations; contribute to constructive societal mobilisation and compelling policy-making; advocate for development as a better alternative to growth; encourage the integration of human and environmental health interests; and encompass triple-bottom-line-inspired outcomes. Focusing on community capital productivity and regeneration may be the key to advancing healthy and sustainable communities.

"Toward Sustainable Communities is the definitive guide to creating vibrant, healthy, equitable, and prosperous places. This completely revised 5th edition organizes community resources into 8 interrelated forms of capital, creating an innovative framework for maximizing social, economic, and environmental benefits."--

Sustainability and the social economy are two approaches that provide critiques of mainstream economic growth based on the failure to integrate environmental and social concerns. This article explores the potential for community transformation by bridging these two approaches — bringing more environmental considerations into the social economy and using the social economy to advance equity concerns within sustainability. We examine this potential through local food initiatives in two Canadian cities that are striving to create a synthesis of social and environmental objectives to achieve structural change in the way that food is produced, accessed and consumed. Both projects are founded on commitments to sustainable community development and social justice. While the initiatives illustrate the potential for community transformation by integrating sustainability and the social economy, they also illustrate the challenges associated with an incremental approach to change in the context of competition with mainstream economic activities that are heavily subsidized and do not account for negative social, economic and environmental externalities.

The increasing collaboration of universities with outside organizations in international development work has been accompanied by a number of issues and challenges. Some of these challenges are common to collaborative North-South development initiatives in general (for example, logistical difficulties, cultural differences, unequal power relations), while others are rooted in the particular values, structures, and regulations of universities and their partners (for example, systems of career advancement, grant recognition, disciplinary fragmentation, government-mandated regulations). These issues are addresses within the context of a CIDA/UPCD project to create a CED program in Mexico, involving a partnership between a Canadian public university, a Mexican private university, and a Mexican NGO oriented toward community development and poverty alleviation.

"When citizens take collaborative action to meet the needs of their community, they are participating in the social economy. Co-operatives, community-based social services, local non-profit organizations, and charitable foundations are all examples of social economies that emphasize mutual benefit rather than the accumulation of profit. While such groups often participate in market-based activities to achieve their goals, they also pose an alternative to the capitalist market economy. Contributors to Scaling Up investigated innovative social economies in British Columbia and Alberta and discovered that achieving a social good through collective, grassroots enterprise resulted in a sustainable way of satisfying human needs that was also, by extension, environmentally responsible. As these case studies illustrate, organizations that are capable of harnessing the power of a social economy generally demonstrate a commitment to three outcomes: greater social justice, financial self-sufficiency, and environmental sustainability. Within the matrix of these three allied principles lie new strategic directions for the politics of sustainability. Whether they were examining attainable and affordable housing initiatives, co-operative approaches to the provision of social services, local credit unions, farmers' markets, or community-owned power companies, the contributors found social economies providing solutions based on reciprocity and an understanding of how parts function within the whole--an understanding that is essential to sustainability. In these locally defined and controlled, democratically operated organizations we see possibilities for a more human economy that is capable of transforming the very social and technical systems that make our current way of life unsustainable."--
