The number of geese in the Netherlands is increasing. Each autumn they fly from Scandinavia and Russia to spend the winter in the Dutch fields. It is generally assumed that the restrictions on goose hunting have been responsible for the population increase, but graduate Johan Mooij thinks that the geese have changed the destination of their seasonal migration from the Caspian Sea and Turkey to Western Europe. Their overall number therefore has not increased. His research results however are debatable and his promoter is not sure whether the goose population has increased or not. Further research in Russia should help towards providing a definite answer.
Tourism is the fastest growing industry in the world. Costa Rica, a country with lots of sun, sea and nature, is profiting from this trend. However, lack of environmental policy and control is threatening the natural diversity there. The WAU working group on Recreation and Tourism is assisting in developing a sustainable development treaty between Holland and Costa Rica, to combine tourism and nature conservation. Wageningen is involved in establishing an educational programme in this field near the Papagayo peninsula, an area visited by many tourists. The promotion of small-scale tourism may trigger local development, says the working group.
