RESUMOPresente na agenda global durante praticamente toda a segunda metade do século 20 e início do 21, e formalmente institucionalizado em 1987 pela Organização das Nações Unidas, o Desenvolvimento Sustentável é, hoje, uma das maiores preocupações da humanidade e um discurso em constante disputa. O conceito apresenta relação com os conceitos desenvolvimento e sustentabilidade, e o Desenvolvimento Sustentável é importante para a compreensão e resolução de problemas enfrentados pela humanidade. A literatura mostra que é um conceito ainda em construção. Este artigo busca apresentar o Desenvolvimento Sustentável enquanto campo de disputa ideológica que enfrenta embates conceituais e políticos. É importante reconhecer que o Desenvolvimento Sustentável não está desvinculado dos níveis de consumo e produção de que trata o seu escopo conceitual. Por isso, as relações de poder rumo ao Desenvolvimento Sustentável precisam desembocar em um agenciamento coletivo. Assim, o objetivo deste estudo é descrever a disputa pelo conceito de Desenvolvimento Sustentável existente entre as teorias da Sustentabilidade Forte e da Sustentabilidade Fraca. Os resultados obtidos foram analisados pelos autores e ajudaram a traçar um panorama temporal dos embates travados entre estas duas linhas teóricas antagônicas.Palavras-chave: Desenvolvimento sustentável.

SUSTAINABLE DEVELOPMENT: A DISCOURSE IN DISPUTEABSTRACT Present on the global agenda during virtually the entire second half of the twentieth and early twenty-first century, and formally institutionalized in 1987 by the United Nations, Sustainable Development is today one of humanity's greatest concerns and a discourse in constant dispute. Coming from the combination of concepts of development and sustainability, Sustainable Development is important for understanding and solving problems faced by humanity. However, it is a concept that is still under construction. This article seeks to present Sustainable Development as an ideologically disputed field that faces conceptual and political conflicts. It is important to recognize that Sustainable Development is not unrelated to the levels of consumption and production that its conceptual scope addresses. Therefore, the relations of power towards Sustainable Development must lead to a collective agency. Thus, the objective of this study is to describe the dispute over the concept of Sustainable Development existing between the theories of Strong Sustainability and Weak Sustainability. The results obtained were analyzed by the authors and helped to draw a temporal panorama of the clashes between these two antagonistic theoretical lines.

The ability to create alternatives to social problems in a sustainable way can be understood as social innovation. Social innovation is a way of equalizing social problems, being considered an option for market, state and society failures. Thus, social innovation presents itself as a possible and necessary alternative for solving the problems related to Sustainable Development, especially education. This study seeks, from the perspective of the Innovation Capability, to identify the Capability for social innovation in Associations, Businesses Foundations and Social Businesses that work in the area of Education in the Southeast of Brazil. In this research, the Social Innovation Capability is composed of five factors, namely: Facilitating Leadership; Strategic Intention to Innovate Socially; Democratic Management; Co-creation of Social Innovation and Open Social Innovation. The research methodology is qualitative descriptive. For the data collection, an online questionnaire was sent to a selection of organizations belonging to all three types of organizations studied (Associations, Businesses Foundations and Social Businesses) that work in the area of Education in the Southeast of Brazil.
