Dr. Reinhardt Howeler was born in Indonesia but grew up in the Netherlands. After obtaining his BSc degree in Tropical Agriculture from the International College of Tropical Agriculture in Deventer, the Netherlands, he immigrated to the United States in 1964. He received his MSc degree in Soil Fertility from the University of Missouri in 1966 and a PhD in Soil Chemistry from Cornell University in 1970. He joined CIAT, initially as a postdoc, in June 1970, working on flooded and upland rice, mainly in the Eastern Plains of Colombia. With the establishment of CIAT’s Bean and Cassava Programs in 1973, he was assigned to work on soil and plant nutrition problems for both programs until 1975, when he started working fulltime for the Cassava Program.

In 1986, he was transferred to the CIAT-Bangkok office to work with national programs in many Asian countries in the fields of agronomy and soil fertility management, especially addressing soil erosion issues. After core funding for this program ended in 1994, he obtained special project funding from the Nippon Foundation  and later from the Australian Centre for International Agricultural Research (ACIAR)  to conduct farmer-participatory research (FPR) in collaboration with cassava researchers and extension agents in Cambodia, China, East Timor, Indonesia, Lao PDR, Thailand, and Vietnam, until his retirement in June 2009.

The most interesting and rewarding part of his 39-year career at CIAT was to work directly with cassava farmers in many different countries and see how the FPR approach enhanced the adoption of new cassava varieties and more-sustainable production practices, which in turn increased cassava yields in Asia and markedly improved the lives of many poor farmers.

Dr. Howeler is currently working as a cassava consultant. He has authored or co-authored over 200 publications, and edited 13 books on cassava. He has received numerous awards for his work in Asia, including a Royal Decoration in the Third Class of the Most Exalted Order of the White Elephant granted by the Thai government.

Carlos Lascano is a Colombian citizen, who in 1965 completed undergraduate training in Agronomy at the Escuela Agrícola Panamericana in Zamorano, Honduras. Later he attended the University of Arizona in Tucson where he completed a BS in Agriculture in 1967 and an MS in Animal Science in 1970. After completing his MS studies, he joined a Feed Company (SOLLA) in Medellín, Colombia, where he served as Head of the Technical Department and was responsible for formulating feed rations for different kinds of livestock. In 1973 he joined CIAT and was based in Cali, Colombia, for 3 years as Coordinator of an International Training Program in Tropical Livestock. In 2006 he was awarded a scholarship by the Rockefeller Foundation and enrolled as a graduate student at Texas A &M University, College Station where he obtained a PhD in Ruminant Nutrition in 1979.

In late 1979 he came to CIAT as a Post Doctoral Fellow in the Tropical Forages Program and in 1982 he was appointed Senior Staff, responsible for research on forage quality and uses. During this time, he carried out long-term grazing experiments in the Eastern Plains of Colombia to assess productivity and tolerance of grass and grass+legume pastures under low fertilizer inputs and different management systems. These experiments proved to be a valuable resource to study the dynamics of vegetation and soil properties under contrasting management systems. In the 90s, Lascano established a dairy research facility in the Quilichao research station, located in the department of Cauca, to evaluate forage quality using short-term grazing experiments with milking cows. He also contributed by supervising numerous postgraduate theses to defining negative and positive effects of condensed tannins in legumes and to establishing differences among species and genotypes in tannin content and biological activity. He made valuable contributions to understanding how environmental factors affect the concentration and chemical properties of condensed tannins in legumes.

In 1997 Lascano was appointed Leader of the Tropical Forage Program and for 10 years he led an international multidisciplinary team dedicated to improving forages for different tropical agro-ecosystems and production systems. Some important achievements under his lead include: 1) selection of multipurpose legumes with adaptation traits to drought and low fertility soils; 2) establishment of a private-public partnership to fund, develop, and promote use of improved hybrids of Brachiaria, which is the most widely, planted grass in Latin America and South East Asia; 3) development of methodologies to screen forages for quality and anti-quality traits and for adaptation to biotic and abiotic constraints; 4) discovery of endophytic fungi in tropical forage grasses; and 5) identification of a mechanism for controlling the biological nitrogen inhibition (BNI) capacity of Brachiaria humidicola, which has enormous implications for nitrogen-use efficiency in crop–livestock systems .

His published work comprises over 80 articles and book chapters. In recognition of his contribution to global forage/livestock research, he was invited to read the Harry Stobbs Memorial Lecture in Australia in 1990, was elected President of ALPA (Asociación Latinoamericana de Producción Animal) for a three-year term (1997–2000), and received CIAT’s Outstanding Senior Staff Award in 1966. Upon his retirement from CIAT in 2007, he was appointed Emeritus Scientist.
