Regionalisation aims at delimiting provinces within which physical conditions, chemical properties, and biological communities are reasonably homogeneous. This article proposes a synthesis of the many recent regionalisations of the open-sea regions of the Mediterranean Sea. The nine studies considered here defined regions based on different, and sometimes complementary, criteria: dynamics of surface chlorophyll concentration, ocean currents, three-dimensional hydrological and biogeochemical properties, or the distribution of organisms. Although they identified different numbers and patterns of homogeneous regions, their compilation in the epipelagic zone identifies nine consensus frontiers, eleven consensus regions with relatively homogeneous conditions,...

Using multi-agent modeling technique to regionalize key processes and patterns of sustainable agricultural cropping systems in the North China Plain AgEcon
Roth, Andreas; Pan, Ying; Yu, Zhenrong; Doluschitz, Reiner.
The North China Plain (NCP) covers an area of around 328,000 km2 and is one of the most important regions of cereal crop production in China. Wheat and maize rotations and one season cotton are the most common cropping systems. The region contributes at an amount of about 50% to the countries wheat production and about one third of maize yields. Crop production in the NCP was focused in the last decades on increasing yields to meet the growing food demand accompanied by the limitation of arable land as a result of urbanization rate i.e. of the Beijing District. Food production needs can nowadays only be achieved by the optimization of agricultural management, i.e. fertilizer input, irrigation, improved crop rotations. The focus on increasing yields raised...
