In many tropical and subtropical countries, deforestation is ongoing at an alarming rate. It has not only consequences for the subsequent procurement of seed for afforestation and reforestation but, in many cases, it results in loss of valuable gene resources and/or their genetic deterioration. Often the availability of seed is a serious impediment to reforestation. The provision of high quality seed for planting is frequently a problem in many tropical countries. In some cases seed availability of a whole species may be inadequate; in others it may be difficult to procure seed from particular sources which have proved to be best adapted to the environmental conditions for the introducing countries.Danida Forest Seed Centre now part of Department of Geosciences and Natural Resource Mangement (IGN) under University of Copenhagen (UCPH) has, for many years, worked with the development of decentralized tree seed procurement models to ensure quality tree seed and planting material is available for farmers in Asia and Africa, for whom trees play an important role sustaining their livelihood. Drawing up specific models and testing those in practice is necessary for continuously being able to provide relevant and well founded information about decentralized tree seed procurement models to farmers in tropical countries.
