Urban areas are the most dynamic region on earth. Their size has been constantly increased during the past and this process will go on in the future. Since there is no standard policy and guidelines for construction of buildings and urban planning, cities tend to have irregular growth. Many cities in the world face the problem of urban sprawl in its suburbs. So issues of urban sprawl need to be settled with the help of technologies such as satellite remote sensing and automated change detection.

With the availability of very high resolution multispectral imagery, it is possible to identify small features in urban environment. Because of the multiscale feature and diverse composition of land cover types found within the urban environment, the production of accurate urban land cover maps from high resolution satellite imagery is a difficult task. This paper demonstrates the potential of 8 bands capability of World View 2 satellite for better automated feature extraction and discrimination studies.

Land cover generated from satellite images is widely used in many real-world applications such as natural resource management, forest type mapping, hydrological modeling, crop monitoring, regional planning, transportation planning, public information services, and so on. Moreover, land cover data are one of the primary inputs to many geospatial models.

Land use change is one of the main stress factors on ecosystems near urban areas. We analysed land use dynamics within Xochimilco, a World Heritage Site area in Mexico City. We used satellite images and GIS to quantify changes in land use/land cover (LULC) from 1989 to 2006 in this area, and a Markov projection model to simulate the impact of different management scenarios through to 2057. The results show an alarming rate of urbanisation in 17 years. LULC change runs in one direction from all other land use categories towards urban land use.

Starting in the 1990s, the Vietnamese state sought to expand and modernise the country’s urban system after four decades of anti-urban policies. This paper examines the reworking of the socialist land regime that followed from this shift. It begins by explaining how new legislation and institutions combined market and socialist principles to lure domestic enterprises into realising the state’s new urban ambitions. It then shows how this hybrid reordering of policy triggered local experiments with periurban land redevelopment and new forms of alliances between the state and private capital.

This document focuses on the Synthesis report on Large-scale land based investments in Africa. The specific objective of the work is to prepare an assessment report on LSLBI in Africa with a view to building knowledge and drawing lessons based on best practices for future LSLBI deals that lead to win-win outcomes. In order to do so five regional assessments have been engaged in and are synthesized in this continental synthesis report.

The African Peer Review Mechanism (APRM) is a mutually agreed instrument established in 2003 by the African Union in the framework of the implementation of the New Partnership for Africa’s Development (NEPAD). The objective of the APRM is to foster the adoption of policies, standards and practices that lead to political stability, high economic growth, sustainable development and accelerated regional and continental integration.

Scientific evidence indicates that global warming could well lead to a sea-level rise of 1 meter or more in the 21st century. This paper seeks to quantify how a 1-meter sea-level rise that would affect coastal wetlands in 76 developing countries and territories, taking into account how much of wetlands would be submerged and how likely the wetlands would move inland as the coastline recedes. It is estimated that approximately 64 percent of the freshwater marsh, 66 percent of Global Lakes and Wetlands Database coastal wetlands, and 61 percent of brackish/saline wetlands are at risk.

This housing policy in developing
countries, conjectures and refutations article discusses
housing policy in developing economies. It examines recent
research findings in light of earlier arguments as to the
benefits of more market-oriented approaches. It also looks
at whether the recommendations of earlier work have been
refuted or developed in subsequent analyses and policy
measures. In particular, it reviews the empirical analysis
