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

This paper examines the effects of
urbanization on development and growth. It begins with a
labor market perspective and emphasizes the importance of
agglomeration economies, both static and dynamic. It then
argues that more productive jobs in cities do not exist in a
void and underscores the importance of job and firm
dynamics. In turn, these dynamics are shaped by the broader
characteristics of urban systems. A number of conclusions

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 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

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

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

This paper examines the employment
growth of Indian districts from 2000 to 2010 in the
manufacturing and services sectors. Specialization and
diversity metrics that combine industries in both sectors
are calculated and related to subsequent job growth. The
analysis finds robust and consistent evidence that the
diversity of industries in the district across the two
sectors links to subsequent job growth. Somewhat

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

As the developing world rapidly
urbanizes, the demands on transport systems also grow often
at a faster pace than the population. Given the above
tendency, an effective and coordinated approach to urban
transport requires that sound policies be put into place.
Such policies enunciate the direction that a government
wants to take; they lay the basic framework for downstream
planning as well as project identification and

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

This report provides Mayors and other policymakers with a policy framework and diagnostic tools to anticipate and implement strategies that can avoid their cities from locking into irreversible physical and social structures. At the core of the policy framework are the three main dimensions of urban development.
· Planning— where the focus is on making land transactions easier, and making land use regulations more responsive to emerging needs especially to coordinate land use planning with infrastructure, natural resource management, and risks from hazards;
