The concept of development and the ways of achieving it have been widely criticised from various viewpoints. In the face of the apparent obsolescence of long-standing models, the novel Buen Vivir approach (roughly translated as ‘living well’ or ‘good living’), which has arisen in different parts of Latin America, may offer an alternative paradigm. However, the implementation of policies that could lead to this Buen Vivir model requires profound changes that follow a range of complex transitions, which may often even seem contradictory in countries like Ecuador, where this approach has already been enacted in the new constitution and laws but where old development practices still continue. Accepting the plurality of visions on Buen Vivir (from the indigenous ontology to the ‘Western–modern’ approach), while at the same time positing common ground in which to define a new development strategy able to overcome a natural resource extraction-based economic pattern, is one of the immediate challenges.

This article analyzes the potential of the social and solidarity economy (SSE) to foster the sustainable development goals (SDGs). Local public policies play an important role in supporting both the SSE and SDGs. We select a case study of four SSE projects of a local development agency in the Basque Country, where the SSE has a considerable presence through diverse forms and experiences. We address how these projects, which are implemented in a coordinated and transversal manner, contribute to many specific targets within SDG goals number 8 (growth and decent work), 12 (sustainable consumption and production patterns), and 5 (gender equity). However, some limitations have also been identified: (i) trade-offs, in both SSE and SDGs, between economic growth and other aims centered on environmental sustainability; and (ii) avoidance of handling issues, which limits a systemic transformation.

The social and solidarity economy (SSE) has gained worldwide attention over the last decade. It represents a host of diverse economic activities which take different forms in each country, but which share solidarity values that are alternatives to mainstream market economic logics. In Ecuador, the SSE acquired legal status in the 2008 Constitution that aimed to foster an alternative development model based on the Buen Vivir (BV) paradigm. However, despite a broad new regulatory framework for the SSE, the implementation of specific policies faces significant challenges. This article, based on fieldwork and interviews with many stakeholders, critically analyzes the transformative scope of the policies of the main newly created institution (IEPS—Instituto de Economía Popular y Solidaria). We discuss policy challenges focusing on trade-offs for small rural producers due to their dependent market integration and overall flaws in fulfilling SSE solidarity values.
