During those years I held a number of positions in national and non-governmental organizations, active in the field of development, peace, human rights and refugee assistance. (See this website: Curriculum Vitae) However, in 2017 I was struck by a severe heart attack. It was a narrow escape. I had to give up lecturing and to restrict other activities. Since then, I focus on writing essays and books.
Since around 1980 I had written many essays on development and globalization. Selections of these were brought together in four books: De kritische grens (1994), Catalysing Develoment (2004), Willens en wetens (2005) and Het pantser afleggen (2008). After my return from Sudan, I concentrated writing on conflict and peace, human rights and sustainable development. A number of these texts were collected in two books: Op zoek naar een nieuwe kaart (2015) and The Geography of Human Rights (2017). In other essays I discussed the changing political climate since the turn of the centuries and consequences for social democracy. (see this website: Books, Essays and Speeches). Thereafter I wrote books on the recent history of some countries and regions. In my book Strijd rond de Grote Meren (2018) I described developments after the genocide in Rwanda. In Suriname. Van wingewest tot natiestaat (2003) I discussed the decolonization of this country and its aftermath. Presently I am writing a book on countries in the Horn of Africa.
