Society Engagement on International Response to Desert Locust

Lewis-Burke Associates introduced a scientific society to the contacts at the Food and Agricultural Organization who were leading on the global response to the desert locust crisis in the Horn of Africa.

By facilitating this introduction, Lewis-Burke enabled the society to raise its international profile, enable its members to advise on the Desert Locust response, and to plan awareness raising events about international coordination efforts to address pest management that would not have otherwise been possible.


Leading Advocacy for Wildfire Research Funding

Lewis-Burke worked with a large public research university to initiate an appropriations strategy to increase federal wildfire research funding and coordination. By working with university researchers, university government relations, and members of Congress, Lewis-Burke helped a university get out ahead of its peer institutions on an issue that is quickly gaining national attention.


Elevating the Profile of Coastal Sustainability

To support a university client’s multi-million-dollar investment in a new, interdisciplinary Coastal Sustainability Initiative, Lewis-Burke developed a multi-prong federal relations strategy to raise the profile of the new associated Institute and position the university for federal funding opportunities in sustainability research.  As part of the execution of this strategy, Lewis-Burke worked with relevant Members of Congress to host a briefing on Capitol Hill showcasing the university’s expertise in sustainability and featuring the participation of several leadership officials at key funding agencies.  This event also served as a platform for promoting authorization legislation focused on federal programs that support coastal resilience and sustainability research.  Concurrently, Lewis-Burke worked directly with research faculty on campus to help position the university for success in competing for a variety of federal funding opportunities.  This aspect of the strategy leveraged Lewis-Burke's ability to facilitate high-level agency meetings and contribute to the development of white papers and other promotional materials.  Finally, Lewis-Burke used its ability as a convener to assist the client in launching a university consortium focused on sustainability research.  This helped widen the reach of the initiative and engaged key Members of Congress and their staffs in a roundtable discussion on Capitol Hill which Lewis-Burke organized.  These actions collectively enabled the university to raise the profile of the new sustainability initiative among its peer institutions, key decision-makers at federal agencies, and Members of Congress.


Authorization of Agriculture Advanced Research and Development Authority (AGARDA)

Lewis-Burke worked closely with Senate Majority and Minority staff to provide input for the new Agriculture Advanced Research and Development Authority (AGARDA) Pilot, authorized in the 2018 Farm Bill. This included everything from the general scope of the program to technical assistance on specific mechanisms AGARDA would be authorized to use.

The goals of AGARDA, as summarized from the legislative text, are to develop and deploy solutions to protect against threats to agriculture and food in the US; overcome barriers to enhance export competitiveness, environmental sustainability, and resilience to extreme events; ensure the U.S. maintains its leadership in developing agricultural technologies, research tools, and qualified projects and products that increase economic competitiveness and security; and undertake advanced research and development in areas industry by itself is not likely to go.

Since its authorization, Lewis-Burke has worked with an informal coalition of other interested stakeholders to bolster congressional support for AGARDA.
