Before he completed a combined BSc- and MSc-level study of agronomy with additional master-level courses in Applied Social Anthropology (U-CPH) and Tropical Agriculture (1-3) at The Swedish Agricultural University.

Kenya, Rwanda, Ghana, Uganda, and Tanzania for leading organisations like U-CPH, Care International in Rwanda, International Centre for Research in Agroforestry, and Kenya Forestry Research Institute Agroforestry Division. He has also travelled, studied, and presented research results in e.g. India, Benin, and Brazil, Torsten has agricultural experiences from Denmark and Spain. Mandal analysed research needs, plus developed, documented, and published several improved, low-input methods. They make it easier, faster, and more affordable for also small farmers in the tropics and subtropics, to establish trees, conserve and improve soil fertility, direct seed challenging seeds, and manage multipurpose tree legumes better among crops. He has published at many levels on these topics since 1983 in Danish and English. He has experience with teaching at all levels (incl. African farmers and MSc at U-CPH). He is now a freelance agronomist providing advice, advisory-, technical- and teaching services, proposal writing etc. More details can also be found at https://torstenmandal.wordpress.com.
