Land means the basic part of the natural environment, the basic instrument of human life, activity and immovable property, which is being disposed of in the process of land relation. Land should be used when coordinating private and public interests as well as environment protection requirements.

The paper focuses on relocation, retreat, zoning, insurance, and subsidy as major dimensions of coastal hazard mitigation measures that have resurfaced as potent forces for combating coastal inundation and climate change. It reviews the issues surrounding the practice of these measures and discusses compatibilities of policies, engineering measures, and natural defense. Property rights, development interest, and distorted financial incentives pose as main barriers to coastal relocation and retreat policies in hazard-prone areas.

Land policies are of fundamental importance to sustainable growth, good governance, and the well-being of, and the economic opportunities open to, both rural and urban dwellers - particularly the poor. To this end, research on land policy, and analysis of interventions related to the subject, have long been of interest to the Bank's Research Department, and other academic, and civil society institutions.

The accumulation of decent housing matters both because of the difference it makes to living standards and because of its centrality to economic development. The consequences for living standards are far-reaching. In addition to directly conferring utility, decent housing improves health and enables children to do homework. It frees up women's time and enables them to participate in the labor market. More subtly, a home and its environs affect identity and self-respect.

The great 21st-century migration into cities will present both a great challenge for humanity and a significant opportunity for global economic growth. This paper describes the diverse patterns that define this metropolitan migration. It then lays out a framework for understanding the costs and benefits of new arrivals through migration's externalities and the challenges and policy tradeoffs that confront city stakeholders.

Housing matters to the livability of cities and to the productivity of their economies. The failure of cities to accommodate the housing needs of growing urban populations can be seen in the proliferation of poorly serviced, high-density informal settlements. Such settlements are not new in the history of rapidly growing cities, their persistence results as much from policies as from economics and demographic transition. Slums have attracted most of the attention on urban housing in developing countries, and the Millennium Development Goals have given prominence to their reduction.

This report aims to extract lessons on slum upgrading and involuntary resettlement policies and practices learned from the process of addressing the Badia East case, which involved complex interactions between affected people, NGOs, the Bank and Lagos State Government.

The tsunami that originated from the Indian Ocean in 2004 wreaked massive destruction, killing more than 130,000 people and displacing half a million individuals in Aceh, Indonesia. More than 800 kilometers of coastline was affected, and close to 53,795 land parcels were destroyed. The land administration system sustained significant damage because documentation of land ownership was washed away along with people's houses and other possessions in the affected communities. Physical boundary markers, including trees and fences, also disappeared.

All countries have a formal economy and an informal economy. But, on average, in developing countries the relative size of the informal sector is considerably larger than in developed countries. This paper argues that this has important implications for housing policy in developing countries. That most poor households derive their income from informal employment effectively precludes income-contingent transfers as a method of redistribution.

This paper reviews the evidence about the effects of urbanization and cities on productivity and economic growth in developing countries using a consistent theoretical framework. Just like in developed economies, there is strong evidence that cities in developing countries bolster productive efficiency. Regarding whether cities promote self-sustained growth, the evidence is suggestive but ultimately inconclusive. These findings imply that the traditional agenda of aiming to raise within-city efficiency should be continued.

This note provides a short overview of urban land and housing market performance in Punjab Province of Pakistan. It describes the characteristics of well-functioning urban land and housing markets and argues that, at present, the Punjab's urban land and housing markets are not performing well.
