About

Erika Styger is a tropical agronomist and the director of the Climate-Resilient Farming Systems Program in the Department of Global Development. The program mission is to improve tropical smallholder farming systems through ecological approaches for greater productivity and resilience to climate change. It is a project-based program, combining research and community-based development approaches. Styger collaborates with partners ranging from local community-based organizations to international organizations in Africa, Asia, Latin America and the Caribbean, and most recently, in the USA.

Styger is a development practitioner, scientist, educator and mentor. She specializes in tropical cropping and farming systems, agroforestry, agrobiodiversity, alternatives to slash-and-burn agriculture, land regeneration, adaptation to climate change, participatory approaches, and for the past 15 years has focused on the System of Rice Intensification (SRI), an agro-ecological and climate-smart rice production methodology. She is also a Faculty Fellow in the Cornell Atkinson Center for Sustainability.

Prior to joining Cornell University, Styger worked on the design, implementation and evaluation of numerous research and development programs, and led field studies for the World Bank, FAO, UNDP, CGIAR Centres ICRAF (World Agroforestry Centre), and IITA (International Institute of Tropical Agriculture); for the Swiss Agency for Development and Cooperation, for US consulting firms Chemonics Inc., Development Alternatives Inc., and Abt Associates Inc., for the MDG Center West and Central Africa (EARTH Institute, Columbia University), and the international NGOs Africare, Catholic Relief Services, Oxfam and SRI Global Inc. In addition to her US-based work, she resided for more than 11 years in Benin, Madagascar, Mali, Rwanda and Zimbabwe, where she worked directly with farming communities to develop agricultural and agroforestry innovations in the tropical highlands, arid, semi-arid, subhumid and humid climate zones.

Styger joined Cornell in 2010 to set up and lead the System of Rice Intensification (SRI) International Network and Resources Center (SRI-Rice), with a mission to advance and share knowledge about SRI, to improve the technical implementation of the SRI methodology, and to support networking among interested organizations and individuals around the globe. During that six-year period, Styger traveled to 29 countries in Asia, Africa, Latin America, and the Caribbean to strengthen local and national SRI programs via technical trainings, workshops, field visits, and by providing technical and research assistance. Together with national partners in West Africa, Styger led the design and was the technical lead for the implementation of the largest SRI project to date, spanning 13 countries in West Africa. The project trained and monitored 50,000 SRI farmers over three years. A follow-up project in the same 13 West African countries, building on these accomplishments, is expected to launch in 2021, employing a new Climate-Resilient Rice Production (CRRP) approach. It will be based on the System of Rice Intensification (SRI) methodology in combination with location-specific sustainable land and water management practices (SLWM), and, if indicated, with integrated pest and disease management (IPM).

In 2017, Styger founded the Climate-Resilient Farming Systems program. Its on-going projects are indicated below.

Styger has a PhD in Crop and Soil Sciences from Cornell University, and a MSc in Agronomy (Diplomierter Ingenieur-Agronom) from the Swiss Federal Institute of Technology (ETHZ) in Zurich.

Research and extension approach

As an agronomist, Styger’s work focuses on improving agricultural systems by changing agronomic practices to benefit both smallholder farmers and the environment. To this end, she prefers to work directly with farmers in their fields, responding to their stated needs, and to support them in developing innovations. Ideas emerge from in-depth dialogue with farmers, bringing together local understanding and knowledge with formal technical and scientific knowledge. This innovation process is iterative and circular, and Styger often combines research and extension approaches rooted in both the social and the biophysical sciences. Once farmers agree on what should be done, Styger then designs simple but vigorous testing protocols to collect technical and economic data, which can indicate what works and what does not work well, and which can later be aggregated. In their everyday work, farmers constantly make observations and innovate in their fields. Styger sees her role to catalyze and strengthen these positive processes, and to help address emerging problems and constraints. Working directly in farmers’ fields allows neighboring farmers to directly observe and learn from this experience, and adopted changes are more easily embedded in the social and cultural fabric of the communities. For Styger, this is the most efficient way to create locally appropriate solutions and sustainable impact.
