摘要:The urgency of charting pathways to sustainability that keep human societies within a "safe operating space" hasnow been clarified. Crises in climate, food, biodiversity, and energy are already playing out across local and global scales andare set to increase as we approach critical thresholds. Drawing together recent work from the Stockholm Resilience Centre, theTellus Institute, and the STEPS Centre, this commentary article argues that ambitious Sustainable Development Goals are nowrequired along with major transformation, not only in policies and technologies, but in modes of innovation themselves, to meetthem. As examples of dryland agriculture in East Africa and rural energy in Latin America illustrate, such "transformativeinnovation" needs to give far greater recognition and power to grassroots innovation actors and processes, involving them withinan inclusive, multi-scale innovation politics. The three dimensions of direction, diversity, and distribution along with new formsof "sustainability brokering" can help guide the kinds of analysis and decision making now needed to safeguard our planet forcurrent and future generations
