This paper uses district level data to
estimate the general relationship between climate, income
and life expectancy in Peru. The analysis finds that both
incomes and life expectancy show hump-shaped relationships,
with optimal average annual temperatures around 18-20ºC.
These estimated relationships were used to simulate the
likely effects of both past (1958-2008) and future
(2008-2058) climate change. At the aggregate level, future

The purpose of this Independence
Evaluation Group (IEG) special study is to illuminate the
scale and scope of Bank support for municipal development
and to draw specific lessons from the achievements and
failures of a sample of individual projects. The study
focuses on three dimensions of municipal management:
planning, finance, and service provision that figure
repeatedly in Bank financed municipal development projects

Trade policy reforms in recent decades
have sharply reduced the distortions that were harming
agriculture in developing countries, yet global trade in
farm products continues to be far more distorted than trade
in nonfarm goods. Those distortions reduce some forms of
poverty and inequality but worsen others, so the net effects
are unclear without empirical modeling. This paper
summarizes a series of new economy-wide global and national

Using a nested multinomial logit model
of car ownership and personal travel in Beijing circa 2005,
this paper compares the effectiveness of different policy
instruments to reduce traffic congestion and CO2 emissions.
The study shows that a congestion toll is more efficient
than a fuel tax in reducing traffic congestion, whereas a
fuel tax is more effective as a policy instrument for
reducing gasoline consumption and emissions. An improvement

The 2009 edition of the little green
data book includes a focus section, four introductory pages
that focus on a specific issue related to development and
the environment. This year the focus is on urban areas and
the environment, exploring how cities and climate change are
affecting the way we live and how good public policies can
improve prospects for future generations. Urbanization and
economic growth move in tandem. As emerging market economies

This paper assesses the state of
research and examines priorities for future work in the area
of urbanization and growth. This is done by reviewing and
summarizing the findings of five scoping papers covering the
following topics: urban poverty, the political economy of
urban poverty, urban real estate and housing, urban
infrastructure finance, and external assistance for urban development.

In the vast majority of countries land and housing affordability is a critical contemporary challenge. While in different countries and regions the specificities of the challenge vary, the universal truism is that it is becoming increasing difficult for the vast majority of urban residents to obtain and retain adequate and affordable land and housing.

UN-Habitat and GIZ have developed the Metropolitan Capacity Assessment Methodology (MetroCAM) as a joint contribution to implement urban sustainable development agendas and bring them to the metropolitan scale. It complements the Unpacking Metropolitan Governance series. 

Overview:

La présente ordonnance, prise en application des dispositions de la loi n° 25/2011 du 29 décembre 2011 autorisant le président de la République à légiférer par ordonnances pendant l’intercession parlementaire, fixe les règles générales relatives à l'urbanisme en République gabonaise. La planification urbaine (Titre II), ensemble des études et enquêtes nécessaires pour l’aménagement des agglomérations, comprend schémas directeurs d'aménagement et d'urbanisme et les plans d'occupation des sols.

Today, 370 million people live in cities in earthquake prone areas and 310 million in cities with a high probability of tropical cyclones. By 2050 these numbers are likely to more than double, leading to a greater concentration of hazard risk in many of the world's cities. The authors discuss what sets hazard risk in urban areas apart, summarize estimates of valuation of hazard risk, and discuss implications for individual mitigation and public policy.

This article uses TM images in 1999 and 2006 in Dahua County, selects the driving factors having great impact on urban land use change, and conducts data processing using GIS software. It then uses CLUE-S model to simulate land use change pattern in 2006, and uses land use map in 2006 to test the simulation results. The results show that the simulation achieves good effect, indicating that we can use CLUE-S model to simulate the future urban land use change in karst areas, to provide scientific decision-making support for sustainable development of land use.
