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. His work uses input from collaborators across a range of disciplines (economics, hydrology, agronomy, land use planning) to examine how strategies for adaptation and mitigation can increase agricultural productivity, incorporate a range of ecosystem services and provide resiliance to the uncertainties of a changing climate.
Alternative Water Management Systems in Rice
On the international stage, Ryan has cultivated 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 maintains active research interests in water, nutrient and weed managment in a diverse range of rice production systems (e.g. lowland rice, aerobic rice, AWD and SRI) used in various parts of Asia, Latin America, Africa and North America. Ryan holds a Ph.D. in soil science from Cornell University. He has also been a visiting scholar at the International Rice Research Institute in the Philippines and the Bogor Agricultural Institute in Indonesia.
