Introduction by Dr. Stefan Schmitz: In introducing the session, he said that the talk is focussed on marginality, fragility, uncertainty, instability, food security and rural development. Crisis at the horn of Africa but also experiences from all over the world are major issues of worry and of priority to GIZ. He stated that various aspects of national key sectors come together (e.g cultural, political, environmental etc) and need attention by development agencies. Do all these dimentions of fragility interlink or are they independent? We should link evidence base, research base, scientific base etc., with political situations which is what GIZ is doing. Anneke Trux then spoke on the topic “How can UNCCD and other UN Conventions support and enable sustainable land management in fragile systems?” She started by answering the questions; What is a convention? and What does a convention regulate? She explained that a convention is a treaty among different countries, is an internatinoal legal framework, and that even though it is not a law, partners agree to the terms and aims. A convention regulates strategies, obligations, aims and objectives. She emphasized that since conventions are not laws, the commitment of parties is a major obstacle for implementation.

Agriculture is a major contributor to global carbon dioxide emission according to Prof. Rattan Lal, distinguished professor at the Ohio State University, USA who presented on marginal soils at Tropentag 2011 . He defined marginal soils as “soils of poor quality and characterized by low ecosystem functions and services”. He also underscored the linkages between soils and the ecosystem and spoke about the importance of soil for humanity. He said that when soils get marginalized, people also get marginalized and that when farming occurs, nutrients are removed and these nutrients must be replaced one way or another, otherwise soils then get marginalized. According to him, if the millennium development goals would be achieved, then soils should be taken more seriously and properly protected. Soil degradation Land is needed for human settlement especially with population growth and urbanization, and Prof. Lal estimates that up to about 400, 000 ha of land is needed per year for one million people which means that about 3 million ha is converted to areas of human habitation each year. Another cause of soil degradation he mentioned is the use of top soil for brick/block making as well as use of soil for sale. He stated that, “soils can provide for our needs but not our greed”.
