Since 2003 GIAN-Alumni-Network has organised the following conferences in Iran which are related to the general aspects of Ecosystem Assessment and Environment beyond other topics. In 2010, the subnet of GIAN, GAENSAR (GERMAN ALUMNI ECOSYSTEM NETWORK IN ARID AND SEMI‐ARID REGION) organised specific conferences with the main topic ‘protection and utilization of ecosystems in arid and semi-arid regions’. Three further conferences with similar topics followed in 2011, 2012 and 2013. In those conferences more emphasis has been put on nature conservation and natural resources conditions rather than on anthropogenic changes.
In 2014, the conference’ topic will put more emphasis on anthropogenic changes of the ecosystem in arid and semi-arid regions. Anthropogenic changes of ecosystem are caused by a complex interacting system of elements in a cyclic causal chain. For example, the population growth, the population density, the technological changes in agriculture and industry cause in this chain of interaction the climate change. This change causes the intensity and direction of production e.g. in agriculture in favour of food security for a growing population in every economy. The drivers, in their interaction affect permanently the negative changes of ecosystem temporally and spatially and force the science, economy and society to organise themselves for possible solutions of these anthropogenic causalities.
The conference will follow the objectives of:
