Applying economic sociology to understand the meaning of “Quality” in food markets

This article reviews the concept of the “market” and questions the standard view of the “market” developed by orthodox economic theory. The article highlights how Economic Sociology and Convention Theory is more useful in understanding markets and appreciating markets as social constructs, which are governed by institutions and social orders. This adjustment in the analytical framework to study markets and especially food markets, is useful in unpacking the various dimensions of “quality” in food products and illustrating that “quality” is an institution that is shaped by society and by culture.     

Land administration “best practice” providing the infrastructure for land policy implementation

Land administration systems, and particularly their core cadastral components, are an important infrastructure which facilitates the implementation of land use policies. While most land administration systems traditionally have a primary objective of supporting the operation of land markets, they are increasingly evolving into a broader land information infrastructure which supports economic development, environmental management and social stability in both developed and developing countries. While a great deal of attention is given to land use policies worldwide concerned with such areas as forest management, coastal zone management, environmental sustainability and managing the urban environment, less attention is given to the infrastructures which facilitate the implementation of the associated policies and programmes. Importantly, all these activities rely on some form of land administration infrastructure which permits the complex range of rights, restrictions and responsibilities in land to be identified, mapped and managed as a basis for policy formulation and implementation. As a result, there is an increasing interest in the concept of land administration infrastructures and their core cadastres, in the principles and policies concerned with establishing such infrastructures and in “best practices”. In addressing this need, this paper attempts to explain the evolving concept of land administration infrastructures, the concept of “best practice” and the concept of a land administration “tool box” of principles, policies, laws and technologies which are useful in reforming or re-engineering land administration systems in support of a broader land policy agenda.     

Collaborative growth management in metropolitan Denver: “Fig leaf or valiant effort?”

Metro Vision 2020 is a collaborative effort to manage growth in metropolitan Denver. Based on interviews, surveys and document analysis, an evaluation revealed that it was a well-managed process that raised awareness about growth problems. The efforts also resulted in an approved regional plan that initiated an innovative urban growth boundary policy. However, the lack of broad-based participation, limited understanding of policy effects, and inadequate implementation tools raised doubts about long-term effectiveness. The broader implications are that collaboration at the metropolitan scale needs to explore more participatory models, stronger implementation tools, and institutional structures that will support consensus.     

Detecting the impact of the “Grain for Green” program on the mean annual vegetation cover in the Shaanxi province, China using SPOT-VGT NDVI data

In order to reduce the soil erosion rate on the Chinese Loess Plateau, the Chinese government launched in 1999 the “Grain for Green” program (GfG). The objective of this program was to increase the forest cover on steep slopes in the landscape by planting trees and sowing grasses on former cropland. The program was a massive investment by the Chinese government. By the end of 2005 the GfG-program was implemented in an area of 87,000 km² in which about 400–600 million trees were planted. At present it is not known to what extent this program was successful. This paper examines the effects of the GfG-program on the mean annual vegetation cover in the Shaanxi province. A decadal time series of SPOT VEGETATION imagery from 1998 till 2005 were used to calculate NDVI-values in four counties with different rainfall regimes. By means of a regression between preceding rainfall and NDVI-values the effects of rainfall variability were filtered out. A trend analysis of the corrected NDVI time series pointed out that the GfG-program resulted in a significant increase of the vegetation cover on farmland in the northern part of Shaanxi province. In the southern part of the province, which has a more humid climate and large areas of irrigation farmland no significant increase of the vegetation cover on farmland could be detected.
