This volume is organized as follows.
Chapter one address two questions: how has spatial
concentration evolved with growth and development, and what
are the efficiency implications of too much or too little
spatial concentration? This chapter summarizes the various
models that analyze growth by geographic concentration and
sets the foundation for concepts discussed in later
chapters. Chapter two focuses on urbanization in

Over the coming decades, land policy and
administration, for urban as well as rural areas, will be
critical for Ethiopia's development. The vast majority
of people making up the Federal Democratic Republic of
Ethiopia's (FDRE) predominantly agricultural economy
live in rural areas. Finally, land policies and
administration can contribute significantly to the
objectives of promoting gender equality and protecting

The 2007-2008 upsurge in agricultural
commodity prices gave rise to widespread concern about
investors causing a "global land rush". Large land
deals can provide opportunities for better access to
capital, transfer of technology, and advances in
productivity and employment generation. But they carry risks
of dispossession and loss of livelihoods, corruption,
deterioration in local food security, environmental damage,

This is the second part of land studies
on Northern Uganda designed to inform the Peace, Recovery
and Development Plan (PRDP). This second part of the study,
undertaken during the second half of 2007 in the Lango and
Acholi regions, builds on the first phase conducted in 2006
in the Teso region. This second study has been designed to
present a more quantitative analysis of trends on disputes
and claims on land before displacement, during displacement

Although increased global demand for
land has led to renewed interest in African land tenure, few
models to address these issues quickly and at the required
scale have been identified or evaluated. The case of
Rwanda's nation-wide and relatively low-cost land
tenure regularization program is thus of great interest.
This paper evaluates the short-term impact (some 2.5 years
after completion) of the pilots undertaken to fine-tune the

Secure property rights are considered a
key determinant of economic development. However, evaluation
of the causal effects of land titling is a difficult task.
Since 2004, the Brazilian government, through a program
called "Papel Passado," has issued titles to more
than 85,000 families and has the goal to reach 750,000.
Another topic in public policy that is crucial for
developing economies is child labor force participation. In

As Vietnam enters a crucial period of
urbanization corresponding to its present stage of economic
development, the Government of Vietnam has placed strong
emphasis on developing its system of cities. In accordance
with this objective this Urbanization Review is dedicated to
understanding the key dimensions and aspects of
Vietnam's urbanization process and to identifying
trends, opportunities, challenges and core policy priorities

Interest in farmland is rising. And,
given commodity price volatility, growing human and
environmental pressures, and worries about food security,
this interest will increase, especially in the developing
world. One of the highest development priorities in the
world must be to improve smallholder agricultural
productivity, especially in Africa. Smallholder productivity
is essential for reducing poverty and hunger, and more and

This book provides an overview of the
World Bank's Eco2 cities : ecological cities as
economic cities initiative. The objective of the Eco2 cities
initiative is to help cities in developing countries achieve
a greater degree of ecological and economic sustainability.
The book is divided into three parts. Part one describes the
Eco2 cities initiative framework. It describes the approach,
beginning with the background and rationale. Key challenges

Structural change is a key driver of
rapid growth: countries diversify into new industries, firms
learn new things, people move to new locations. Anything
that slows this structural change is also likely to slow
growth. Because urbanization is one of the most important
enabling parallel processes in rapid growth, making it work
well is critical. Urbanization's contribution to growth
comes from two sources: the difference between rural and

While the economic returns to using
chemical fertilizer in Africa can be large, application
rates are low. This study explores whether this is due to
missing and imperfect markets. Results based on a panel
survey of Ethiopian farmers suggest that while fertilizer
markets are not altogether missing in rural Ethiopia, high
transport costs, unfavorable climate, price risk, and
illiteracy present formidable hurdles to farmer

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.
