    This document provides an overview on land use and spatial development in the Montpelier region and turning points the planning and governance regime. In the first part we give an overview on the land use and regional development of the case study region. In the second part, we introduce the planning system, its major actors and instruments as well as governance aspects to the reader.

    We investigate conceptually and empirically the role of economic incentives in the primary land allocation in China in recent years. A theoretical analysis demonstrates how recent fiscal and governance reforms give rise to land conversion decisions and long run urban spatial sizes much like those generated by competitive land markets with private land ownership. An econometric investigation of Shanghai and the provinces surrounding it demonstrates the presence of rent gradients, often used as an indication of the presence of land markets.

    When pasture land is abandoned, there are, in many cases, inhibitory factors that slow the rate of transition to a natural vegetation. Accordingly, the planned management of restoration has become an important issue in various parts of the world, where environmental conditions can vary widely. Although tree plantations are widely used as a management tool for restoration, there have been few studies addressing the practical aspects of the procedure.

    We focused on land units as landscape characteristics and selected seven typical land units on a land catena comprising two areas of southern Mongolia. Hierarchical analysis was used to test the hypothesis that a land unit's edaphic factors could explain the differences in vegetation responses to grazing.

    Soil organic carbon (SOC) was measured in topsoil samples of agricultural soils from 311 locations of Jiutai County, Northeast China. The spatial characteristics of SOC were studied using the Geographic Information Systems and geostatistics. Effects of other soil physical and chemical properties, elevation, slope, soil type and land use type were explored. SOC concentrations followed a lognormal distribution, with a geometric mean of 1.50%. The experimental variogram of SOC was fitted with an exponential model.
