V. Ryan Haden, Ph.D.

Ryan Haden is an agroecologist and soil scientist with expertise in agricultural strategies to mitigate greenhouse gas emissions and adapt to climate change. His work examines the intersection between water, energy, land use change and sustainable agriculture, with an eye towards understanding the benefits and trade-offs for society and the environment.

Ryan has recently developed carbon accounting methods consistent with international guidelines, which are being used by local governments in California to monitor agricultural emissions and implement community-wide mitigation strategies. His work on climate change adaptation has focused on the links between water management at the field, district and watershed scales. On the international stage, Ryan has cultivated consulting and research partnerships with a range of development organizations based in Asia and Latin America. These projects have involved vegetable, rice and agroforestry systems and sought to enhance adaptive management through participatory methods.

He has been a visiting scholar at the International Rice Research Institute in the Philippines and the Bogor Agricultural Institute in Indonesia.
