Conserving biodiversity in the face of rapid climate change requires a shift in priorities

The field of conservation aims to protect biodiversity-the diversity of life on earth in all its forms. Traditional conservation objectives and measures have already been expanded and modified in response to shifting social values and climate-related challenges. As climate change progresses, we argue that these changes will need to be accelerated. First, an even greater fraction of conservation objectives will need to prioritize the basic well-being of humans, especially in areas where humans are strongly dependent on their natural surroundings. For example, urban biodiversity and low-impact forms of agriculture and forestry that reconcile biodiversity and contributions to humans should increasingly be viewed as compatible with conservation objectives. Second, more conservation measures will need to allow for, and even foster, changes in biodiversity. Indeed, changing species' characteristics and biotic community composition are not only adaptive responses to inevitable climate change but will, in many instances, also be necessary to maintain functioning ecosystems. Conversely, attempts to maintain biodiversity in a historical state will likely become increasingly difficult, expensive, and possibly counterproductive. Finally, in addition to continuing climate adaptation work, conservation efforts will need to focus more on reducing atmospheric carbon concentrations. We explore how collectively these changes are transforming the field of conservation and how they have the potential to lead to a more just and sustainable world despite impending climate change.
