A development response to forced
displacement in the Sahel requires a regional approach. Such
an approach would have the benefits of being able to: (i)
overcome challenges relating to cross--- border movements,
(ii) obtain commitments by host governments to support the
prospects of displaced from neighboring countries and (iii)
facilitate common approaches, shared conceptualization and
learning. A regional approach will be appropriate in the

Urbanization is undoubtedly a key driver
of development - cities provide the national platform for
prosperity, job creation, and poverty reduction. But
urbanization also poses enormous challenges that one is
familiar with: congestion, air pollution, social divisions,
crime, the breakdown of public services and infrastructure,
and the slums that one billion urban resident's call
home. Urbanization is perhaps the single most important

The population of Sub-Saharan Africa
stood at 854 million in 2010. Annual population growth
averaged 2.5 percent, with a relatively high sustained
fertility rate, fostered by the fact that two-thirds of the
population is under 25. The region has the highest
proportion of poor people in the world, with 47.5 percent of
its population living on less than $1.25 a day, as measured
in terms of purchasing power parity in 2008. It is also the

This paper develops a dynamic model that
explains the pattern of population and production allocation
in an economy with an urban location and a rural one.
Agglomeration economies make urban dwellers benefit from a
larger population living in the city and urban firms become
more productive when they operate in locations with a larger
labor force. However, congestion costs associated with a too
large population size limit the process of urban-rural

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

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

Strong boy-bias and its consequences for
young and unborn girls have been widely documented for Asia.
This paper considers a country in Sub-Saharan Africa and
finds that parental gender preferences do affect fertility
behavior and shape traditional social institutions with
negative effects on adult women's health and
well-being. Using individual-level data for Nigeria, the
paper shows that, compared to women with first-born sons,

Urban agriculture contributes to local
economic development, poverty alleviation, the social
inclusion of the urban poor and women, as well as to the
greening of the city and the productive reuse of urban
wastes. Urban agriculture encompasses a wide variety of
production systems in both urban as well as peri-urban
areas. This study examines the contribution of urban
agriculture to livelihoods, food security, health, and the

Section one of the papers provides a
brief overview of the relationship between the Sahel region
of Africa and climate variability trends and predictions,
ultimately posing the primary research question of the
study: Is the Sahel region more likely to have a higher
probability of conflict and migration as a result of climate
change and climate change-related events? In section two,
research and analysis aim to identify causal paths between

This paper focuses on several
interrelated key questions on the geography of development.
Although we herald cities with their industrial bases as
'engines of growth,' does industrialization in
fact drive urbanization?1 What economic activities do cities
of different sizes undertake? Does this change as countries
develop? If so, what are the policy implications? Do
development policies have a big-city bias? If so, what does

Urbanization is the single most
important transformation that the African continent will
undergo this century. More than half of Africa's
population will live in its cities by 2040. In the face of
rapid urbanization, there is a narrow window of opportunity
to harness the potential of cities as engines of economic
growth, and use this as a powerful leverage to achieve
sustainable development and poverty reduction. Despite its
