As a foundation member of the
University of Tropical Agriculture Foundation [www.utafoundation.org ] Ron has
been associated with the online journal Livestock Research for Rural Development
and assists the President Professor T R Preston in setting editorial policy.
This paper sets out editorial policy to not accept papers dealing with
industrialized animal production on the basis that future fossil fuel supply and
costs suggest such systems are inappropriate for development

In 1991 during an assignment in Bangladesh, Ron came across the work of PRISM an NGO that was developing duckweed aquaculture. The ability of aquatic plants to regenerate potable water from sewage and to provide a potential feed for livestock was seen to have enormous potential. Research in the University of Tropical Agriculture, Vietnam developed and Ron was asked to write a book on the potential of Duckweed as a feed for livestock [Duckweed FAO, Rome]. When the largest lake in South America [Lake Maracaibo] suddenly experienced a duckweed bloom that eventually covered 15-20% of the lake’s surface, Ron was one of the scientists called in to attempt to understand the reasons. The report co authored with other members of the University of Tropical Agriculture was subsequently presented to the government of Venezuela.
