“The multidimensionnality of the agricultural and rural question in the Mediterranean militates to engage an euromediterranean mobilization on this subject. Because agriculture is in the middle of the Mediterranean identity and is displayed like an essential determinant for the economies and the companies of the area… The wealth of natural resources and the diversity of the landscapes of the Mediterranean make of it an exceptional ecoregion of this world. However with human development and industrialist this environmental heritage erodes little by little… The impact of the climate change the threats of the biodiversity of the zone, the soil erosion or the polluting emissions caused by energy consumption constitute powerful testimonies of this increasing vulnerability of Mediterranean space…”¹
In addition to its climatic unity, the Mediterranean basin offers both an exceptional biodiversity of ecosystems, with remarkable plant endemism, and very similar agrosystems, with some being very intensive (biodiversity loss) and very traditional (biodiversity conservation).
But this diversity is endangered given that the Mediterranean basin is one of the world areas most affected by climate changes and anthropic activities. For this reason, it deserves a special attention in order to avoid compromising its ecosystem heritage. On one hand, the asymmetry of the trade relationships across the Mediterranean Sea lead South and East Mediterranean countries to increase their offer to the detriment of their environments. On the other hand, ecological pressure in North countries leads to a major thought on ecological intensifi cation of agriculture. Thus, the new ecological conquest of the North-Mediterranean soils requires new integrated strategies whose components are often empirical practices in traditional farming systems of the South.
Research developed around the Mediterranean basin cannot disregard the complexity of the processes involved by global changes, especially in relation to climate and anthropic activities. They can no longer be confi ned to agronomic approaches, and must contemplate more systemic framework². Given the diversity of the Mediterranean eco anthroposystems and the diversity of weakening mechanisms imposed on them, Mediterranean countries are exceptionally suited for developing these research approaches.
Following objectives for restoration of disturbed agrosystems, it is becoming urgent to understand the contribution of invasives species within all degradation functions, and especially in the context of fast programmed elimination of pesticides. To give relevant answers to the questions carrying about the role of the harmful organizations and the invasive species in the degradation of the Mediterranean eco anthroposystems due to parasites, the 1st congress ICPPMA will included the following sessions:
