Research Interests

Maria Carmen Lemos' broad research interests focus on scientific actionable knowledge, especially applied to climate adaptation and the role of knowledge in building adaptive capacity. She is particularly interested in understanding: (a) the co-production of scientific actionable knowledge between scientists and users to inform decision-making to solve sustainability problems, (b) the means through which actionable knowledge scales up especially to inform adaptation action, (c) the use of climate information in building adaptive capacity in different sectors (e.g. drought planning, water management, agriculture, and urban planning), and (d) the impact of technocratic decision-making on issues of democracy and equity.
