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. The paper

The Nigerian labor force, like that of
many countries in Africa, is heavily concentrated in
agriculture. According to World Bank reports, the
agricultural sector in Nigeria grew by about 6.8 percent
annually from 2005-2009. This report focuses on the
characteristics of the agricultural sector and rural
households in Nigeria, and their implications for poverty.
This report examines the relationships using nationally

Climate change presents significant
threats to sustainable poverty reduction in Tajikistan. The
primary impacts on rural livelihoods are expected to stem
from reduced water quantity and quality (affecting
agriculture), and increased frequency and severity of
disasters. Options for farming households to autonomously
adapt (and thereby move from climate vulnerability to
resilience) include adoption of on-farm and off-farm

Across the world, the housing sector
plays a key role in local and national economies, and
expanding access to housing can encourage more equitably
shared economic growth. This report surveys current policy
interventions designed to encourage affordable housing in
East Asia and the Pacific (EAP). The purpose of this report
is to provide a general overview of the recent trends in
urbanization and development in EAP and to consider

Uganda is one of the poorest countries
in Africa with a gross national income (GNI) per capita in
2010 of United States (U.S.) $500 compared with the
Sub-Saharan regional average of $1,170. Uganda's
population growth of over 3 percent per year, one of the
highest in the world, puts a considerable strain on public
sector service delivery, not just for water and sanitation
but also in other areas such as health, education, and

The Government of Sierra Leone (GosL)
and the World Bank (WB) have agreed upon the design and
implementation of a growth poles program (GPP) in support of
the agenda for prosperity (A4P), the GoSL's third
poverty reduction strategy paper (PRSPIII). With support
from the European Union competitive industries and
innovation practice trust fund, the WB has been undertaking
a series of scoping and diagnostic analyses on the GPP since

In the past dozen years, a literature
has developed arguing that urbanization has unfolded
differently in post-independence Sub-Saharan Africa than in
the rest of the developing world, with implications for
African economic growth overall. While African countries are
more urbanized than other countries at comparable levels of
income, it is well-recognized that total and sector gross
domestic product data are of very low quality, especially in

This report was produced for the Global
Program on Forced Displacement and describes why and how to
conduct political economy analysis (PEA) of forced
displacement. It also illustrates how PEA may contribute to
understanding forced displacement crises with nine case
studies: Casamance (Senegal), Colombia, Cote dapos;Ivoire,
Democratic Republic of Congo, Liberia, the Philippines,
Somalia, South Sudan, and Zimbabwe. Forced displacement is

Despite its vast agriculture potential,
Africa is increasingly dependent on food imports from the
rest of the world to satisfy its consumption needs. Food
output has not kept pace with population growth, and more
than 80 percent of production gains since 1980 have come
from the expansion of cropped areas rather than from greater
productivity of areas already cultivated. This paper looks
at the current requirements for seed trade in Africa, the

This issue of Handshake focuses on
natural resource PPPs that are making a difference. In
Cartagena, Colombia, a hybrid public-private agency is
profiled that has standardized water service to residents
while restoring the coast, and in the process, contributed
to political stabilization. Around Africas Lake Victoria, an
environmental management initiative with the potential to
reduce the pollution and resource footprint of industrial

Madagascar has been entirely
unsuccessful in reducing the number of its people that are
poor, or extremely so, in the ten years since 2001, when
poverty was already at a very high level. This well-known
conclusion draws on the analysis of three successive rounds
of the national household expenditure surveys (enquete
periodiques aupres des menages, EPM) conducted by the
Madagascar National Institute of Statistics (INSTAT) in

This paper documents a significant
impact of climate variation on urbanization in Sub-Saharan
Africa, primarily in more arid countries. By lowering farm
incomes, reduced moisture availability encourages migration
to nearby cities, while wetter conditions slow migration.
The paper also provides evidence for rural-urban income
links. In countries with a larger industrial base, reduced
moisture shrinks the agricultural sector and raises total
