Rainforestation farming: concept and history (Part II)


by Victor B. Asio, Dept. of Soil Science, VSU

a) The authors

The Rainforestation concept was developed in 1992 by Dr. Josef Margraf (born: 03 April 1953, died: 26 January 2010) the Project Manager of the ViSCA-GTZ Applied Tropical Ecology Project (Philippine-Germany Environmental Research Program) which ran from 1989 to 1999. Dr. Margraf was born in Bayern Germany, studied biology at the University of Hohenheim in Stuttgart and later specialized in tropical agro-ecology at the same university. He spent years in Ifugao, Northern Luzon conducting his dissertation on the ecology of the Banaue rice terraces under the supervision of the renowned agro-ecologist Prof. Dr. Werner Koch. He obtained his doctorate degree (Dr.sc.agr.) from the University of Hohenheim in 1985.

Dr. Margraf was a soft-spoken, friendly, and kind person. In my personal opinion having known him for almost a decade, he was a brilliant thinker who loved to discuss with anyone about his ecological ideas. A genuine ecologist, he would sometimes sleep overnight below the canopy of a giant ficus tree (locally called balete), to observe the insect diversity, in Mt. Pangasugan. In his past time, he loved playing classical guitar and reading books. In the 1980s, he founded the publishing house Verlag Josef Margraf which in later years became Margraf Publishers Verlagsgesellschaft GmbH. In 1997, after about 9 years at ViSCA, he left for another GTZ project titled Tropical Forest Ecosystems Management in Yunnan, China where he eventually married the Chinese journalist Mingou Li in 2000 with whom he had two daughters Linda and Vanda. In China, he continued his passion for rainforest conservation at a much larger scale and with much more success. In September 2010 he was posthumously awarded the “Green Hero of China”.

The co-author of the concept was the Filipino counterpart of the ViSCA-GTZ Tropical Ecology Project, Dr. Paciencia P. Milan, a renowned biologist, outstanding research manager, and passionate environmentalist who later became the 4th president of ViSCA (renamed Leyte State University). Dr. Milan earned her PhD in Biology from Bowling Green State University, USA in 1985 and her BS in 1967 and MS in 1977 from the University of San Carlos. Primarily for developing and promoting the Rainforestation, she was awarded the Hugh Greenwood Environmental Science Award from the National Academy of Science and Technology of the Philippines.  It was due to her outstanding advocacy and good connections in the higher-ups of the government, that the Rainforestation concept was adopted as a national reforestation strategy of the Department of Environment and Natural Resources in 2004 through the Memorandum Circular 2004-06.

b) The other major contributors

The VSU faculty who have made major contributions to the Rainforestation concept were: Ma. Juliet “Neneng” C. Ceniza (entomology), Buenaventura B. Dargantes (socio-ecology), Dr. Salome B. Bulayog (environmental economics), and V.B. Asio (soil science & geo-ecology).

In one long conversation that I had with Dr. Margraf in a Café shop when he visited me in Giessen, Germany in 1992 (I was there studying soil science, geography, and plant nutrition), he confided that he was so concerned about the widespread destruction of the tropical rainforest. He mentioned that he was in the process of finalizing a concept to rehabilitate degraded lands using native tree species. He said that he was impressed by the Bogor Botanical Garden in Indonesia established by the Dutch in 1815 which boasts a rich collection of mostly native trees and other tropical plants. The famous garden is a clear demonstration that indigenous rain forest tree species can be cultivated.

He told me that he needed the help of the ViSCA faculty members who were at the time pursuing their doctorate degrees in Germany especially M.J. C. Ceniza, B.B. Dargantes,  and myself. So, when I returned to Leyte from Germany for my one-year fieldwork for my dissertation, I did the soil characterization of all the pilot demonstration sites for the testing of the concept called at the time as “Closed Canopy and High Diversity Farming System”. After I finished my PhD in mid-1996, I continued my active involvement in the development of the concept. Dr. S.B. Bulayog, a GTZ scholar who pursued PhD at UP Los Banos, played a role in the development of the concept as well as Ms. Mylene Napiza from the Department of Forestry of ViSCA.

My pedology and geo-ecology group conducted the characterization of the soils of the demonstration sites which served as benchmark data; the periodic soil monitoring by way of the thesis researches of my undergraduate and graduate students (including Daub, S. Goeltenboth, Zoefel, Batistel, Aragon, Sueta, Herzano, and many others) which proved that the soil quality generally improved under the Rainforestation; and the litter decomposition studies which revealed that the leaf litter of the indigenous tree species decomposed at a slower rate compared to those of the exotic species. The slow decomposition minimizes nutrient loss from the forest floor and ensures a continuous supply of nutrients to the growing trees.

c) Other persons who contributed their ideas and studies

The German scientists who in one way or another contributed to the testing and refinement of the concept through their ideas and advice were Prof. Werner Koch and Prof. Friedhelm Goeltenboth (ecology). The graduate students (MSc/PhD) from the University of Hohenheim who conducted various studies to evaluate the impact and suitability of the concept were Carsten Marohn (agro-ecology), Peter Balzer (biology), Christian Müller-Edzards (forest science), Gerhard Langenberger (forestry/vegetation science), Christoph Daub (soil biology), Katrin Zoefel (soil science), and Annette Goeltenboth (biology). 

Among the German graduate students, Peter Balzer had the biggest input into the concept as he was the one who conducted several trials on spacing and arrangement of trees in the demonstration site in Mt. Pangasugan from 1994 to 1996. He also prepared the initial list of native and exotic species suitable for use in the concept (the exotic species served as shade plants for the native species).

A non-technical field staff of the Tropical Ecology Project who deserves a special recognition was Mr. Antonio "Tony" Fernandez from Patag village near the VSU campus. A former shifting cultivator and wildlife hunter, Tony knew almost every tree in the forest by heart. His indigenous knowledge about the forest was crucial to the success of wildlings collection and tree seedlings propagation in support of the Rainforestation farming. 

Not to be forgotten of course were the many research assistants, community organizers, and field laborers who were hired to assist in the development and dissemination of the concept some of whom have become regular staff of ITEEM. 

d) The active promotion and dissemination of the concept

Just like any good product that sells, the Rainforestation strategy attracts a lot of interest from potential "sellers" and users. After the Rainforestation concept has won recognition from various national institutions such as CHED and DENR, thanks to the support from the German partners particularly GTZ and Euronatur, several local and foreign institutions and organizations have become strong advocates of the concept. One obvious reason is that it attracts support from funding institutions. In simple terms, there is money in Rainforestation. As planned, the ITEEM, originally called ITE established in 1999, has assumed the lead role in the promotion and dissemination of the concept to different parts of the country under its past and current directors: Dr. B.B. Dargantes, Dr. M.J.C. Ceniza, Dr. H. Montes, and Dr. M. Bande.

    i've met josef margraf and pacing in a meeting in manila in mid1990s. their concept on the use of native species impressed me. thanks Dr Asio for your informative article.
