Rolf Smeets takes care of this site. He has been working several years as a biology and physics teacher in special education at a school in Nijmegen (the Netherlands).
He studied ecology of the tropical high mountains – in Utrecht and Amsterdam, and worked on ecological research in the Colombian Andes. After graduating, he and some friends founded an ecological travel agency: Ecotravel Nature tours. This was the first ecotourism agency in the Netherlands.
Rolf worked about 6 years in this agency. He organized and supervised many tours. He also wrote documentation for his clients. Thus he gained much knowledge of flora, fauna and geography of many Latin-American countries.

In 1994, Rolf moved to Brazil where again he worked in tourism. He founded and managed a small hotel on Ilha Grande, an island in the neighbourhood of Rio de Janeiro. This was a fantastic full time job. He was responsible for all tasks, from choosing the menus to advertising the hotel clients and making excursions in the area. The hotel won a prize: it was one of the top five ecological hotels in Brazil.

With the travel jitters in the legs, Rolf moved in 1997 to Bolivia, where he worked one year as co-manager of a travel agency for nature and adventure travel. Of course, he supervised a lot of travelling, worked on web design, promotion and other commercial issues for this office: Transamazonas. Rolf also wrote articles for the Bolivian Times and he occasionally advised Bolivian government in the matter of national tourism development.

Back in Holland he became a network manager and worked for some 6 years in the IT field. Finally he decided to share his enthusiasm for biology and switched to becoming a high school teacher in biology and physics.

Now teaching at the Jorismavo, still travelling regularly and hiking, maybe less far, but no less beautiful.

    2 years active in Brazil. Salvador de Bahia (8 months): I did some translation work (Portuguese-German) and worked as a guide for a Eco-operator. I guided Brazilian groups on ecological and cultural-historic excursions and established a mountain bike program. In July 1995 in co-operation with a Dutch investor I started a hotel project on Ilha Grande, Rio de Janeiro. I converted a small private estate into a 3-4 star hotel (Pousada Matariz) for 26 guests and offered possibilities to relax, do boat excursions, canoeing, hiking and scuba. The hotel became a success and won a price (SENAC) being one of the five best Eco-hotels in Brazil. As hotel manager was responsible for public relations, sales, accountancy, being host, etc. Due to private circumstances this project closed in July 1996 upon which I returned to Holland.
  • 1988 – 1994
    Together with two friends I started a foundation for ecological nature tours: Ecotravel Nature tours. This foundation was the first ecotourism agency in the Netherlands and received a lot of attention from the media. I organised a Latin-America travel program and guided many groups in different circumstances on either comfortable hotel tours or primitive trekking tours in Latin-America as well as a few in Africa. I accumulated a lot of knowledge on tropical flora, fauna and geography. I was also responsible for accounting for several years and contributed a lot to the design and layout of our brochures. I also produced many information booklets and other promotional texts. We stopped our activities in 1994.

Comments on biology study:

  • During the first general part of the biology study main emphasis was on general and soil-ecology, systematics of plants and ethology.
  • During the second part specialization followed on the next subjects:
  • Faculty group: Biology and Society (RUU)
    Study under supervision of the Dutch Foundation for the Protection of the Tropical Rainforest (WBTR), coached by Drs. H. Waardenburg from Biology and Society, University of Utrecht (RUU).
    Theme: Study of literature on deforestation and tropical timber use in Malaysia and Indonesia. This was used in a project on tropical timber use and its alternatives by Ir. C. Von Meijenfeldt at the Royal Institute for the Tropics in Amsterdam.
    The report was published in 1985, together with an article in the magazine of the WBTR.
  • Faculty group: Botanical Ecology (RUU)
    Research on vegetation patterns and production of a vegetation map of a chalk-grassland in Zuid Limburg in the south of Holland. This was part of a large scale research project of the biology-faculty in Utrecht.
    Coaching by: Drs. J. Willems and Drs. R. Bobbink. Botanical inventories were carried out and the studied area was mapped. My research combined the use of GIS techniques with pure field biology. This way it was possible to use old vegetation maps again and a prognostic could be made concerning the development of the studied area.
    Publication in: The Utrecht Plant Ecology Report in 1986.
  • Faculty group: Special Botany (UvA)
    Research performed in the frame of a large Dutch-Colombian project, called ECOANDES. This project included various studies in the high Colombian Andes.
    My research involved detailed ecological study of 2 intact tree line formations in the Colombian Andes. Two locations nearby Bogota were used, one in a wet climate region (Parque Nacional Chingaza) and one in a drier region (Neusa).
    Studied items:

    • Botanical composition and 3-dimensional structure of the forest and natural grassland (paramo)-vegetation.
    • Micro climate characteristics.
    • Soil classification and mapping.
    • Determination of the water retaining capacity of the soil and of the cryptogam layer and effects on the drinking water capacity for the city of Bogota.

Report and publication in the Netherlands and in Colombia in 1988.
An additional thesis was produced titled: The effects of mist on the quantification of water added to the system.

Also an course was taken on Tropical High Altitude Ecology.

  • Faculty group: Didactics of Biology (KUN)
    Postgraduate certificate in education (PGCE). Besides intensive theoretical training this included working at a secondary school. Among other activities this included the development of an ecology project. Certificate obtained in 1988
