In this issue, we discuss the Global Bioenergy Partnership and the important work it is undertaking - in collaboration with governments and international organizations - to establish sustainability indicators for bioenergy projects. We also report on the Food for the Cities Initiative, an integrative approach to coordinating FAO's activities in urban and peri-urban areas and sharing best practices with other international and civil society organizations. Finally, we introduce the new water report: Climate change, water and food security.

Methods for the collection and analysis of wood product data in Niger are discussed in this country report. It is organised in two main sections: The country's wooden resources and their potential uses and the analysis of past, present and future trends with their respective subsections. A conclusion is given demonstrating the effects of wood fuel use at the economic, social and environmental levels.

Dans ce numéro, nous examinerons le Partenariat mondial sur les bioénergies et le travail important qu’il a entrepris – en collaboration avec les gouvernements et les institutions internationales – pour formuler des indicateurs de durabilité pour les projets de bioénergie. Nous nous intéresserons aussi à l’Initiative ‘Aliments pour les villes’, une approche intégratrice pour coordonner les activités de la FAO dans les zones urbaines et périurbaines et pour partager les bonnes pratiques avec d’autres organisations internationales et de la société civile.

This paper presents a method to optimise the calibration of parameters and land use transition rules of a cellular automata (CA) urban growth model using a self-adaptive genetic algorithm (SAGA). Optimal calibration is achieved through an algorithm that minimises the difference between the simulated and observed urban growth. The model was applied to simulate land use change from non-urban to urban in South East Queensland’s Logan City, Australia, from 1991 to 2001.

One of the major consequences of expansive urban growth is the degradation and loss of productive agricultural land and agroecosystem functions. Four landscape metrics—Percentage of Land (PLAND), Mean Parcel Size (MPS), Parcel Density (PD), and Modified Simpson’s Diversity Index (MSDI)—were calculated for 1 km × 1 km cells along three 50 km-long transects that extend out from the Adelaide CBD, in order to analyze variations in landscape structures. Each transect has different land uses beyond the built-up area, and they differ in topography, soils, and rates of urban expansion.

Urban expansion has become a widespread trend in developing countries. Road networks are an extremely important factor driving the expansion of urban land and require further study. To investigate the relationship between road networks and urban expansion, we selected Beijing, New York, London, and Chicago as study areas. First, we obtained urban land use vector data through image interpretation using a remote sensing (RS) and geographic information systems (GIS) platform and then used overlay analysis to extract information on urban expansion.

China is rapidly urbanizing and will inevitably face trade-offs between promoting economic growth through further urbanization and protecting fertile farmland against accelerated urban expansion. This paper presents how this dilemma is being addressed in one of the most rapidly urbanizing regions in China, the Pearl River Delta (PRD), by means of assessing urban growth and farmland dynamic, as well as their complex relationships.

Earth observation data can provide valuable assessments for monitoring the spatial extent of (un)sustainable urban growth of the world’s cities to better inform planning policy in reducing associated economic, social and environmental costs. Western Australia has witnessed rapid economic expansion since the turn of the century founded upon extensive natural resource extraction. Thus, Perth, the state capital of Western Australia, has encountered significant population and urban growth in response to the booming state economy.

Urban-rural distinctions are particularly challenging in the context of fast growing cities in the developing world. Through an example of the Indian city of Bangalore, we demonstrate the case for development of more continuous approaches of urban representation that are needed in many parts of the world. Thus even some of the oldest areas in Bangalore, which have been part of an urban center for centuries, exhibit aspects of rurality, as much as other recently developing peri-urban parts of the city.

In Central Java, in addition to the traditional view of urban transition as an aspect of urban industrialization, rural industrialization based on small- to medium-sized enterprises has become a concern, at least since the Indonesian economic crisis in 1997. Combinations of typical urban and rural activities have resulted in certain features of rural-urban transition as the urban population has continued to increase notably. The intention of this paper is to examine how rural-urban transition characterizes the industrialization of Central Java.
