Whether the negative relationship
between farm size and productivity that is confirmed in a
large global literature holds in Africa is of considerable
policy relevance. This paper revisits this issue and
examines potential causes of the inverse productivity
relationship in Rwanda, where policy makers consider land
fragmentation and small farm sizes to be key bottlenecks for
the growth of the agricultural sector. Nationwide plot-level

The most difficult water resources management challenge in the Ganges Basin is the imbalance between water demand and seasonal availability. More than 80 % of the annual flow in the Ganges River occurs during the 4-month monsoon, resulting in widespread flooding. During the rest of the year, irrigation, navigation, and ecosystems suffer because of water scarcity. Storage of monsoonal flow for utilization during the dry season is one approach to mitigating these problems.

Bringing together history and economics,
this paper presents a historical and processual
understanding of women's economic marginalization in
Sub-Saharan Africa from the pre-colonial period to the end
of colonial rule. It is not that women have not been
economically active or productive; it is rather that they
have often not been able to claim the proceeds of their
labor or have it formally accounted for. The paper focuses

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

This paper uses farm panel data from
Indonesia to examine dynamic patterns of land use, capital
investments, and wages in agriculture. The empirical
analysis shows that an increase in real wages has induced
the substitution of labor by machines among relatively large
farmers. Large farmers tend to increase the scale of
operation by renting in more land when real wages increase.
Machines and land are complementary if the scale of

Women make essential contributions to agriculture in developing countries, where they constitute approximately 43 percent of the agricultural labor force. However, female farmers typically have lower output per unit of land and are much less likely to be active in commercial farming than their male counterparts. These gender differences in land productivity and participation between male and female farmers are due to gender differences in access to inputs, resources, and services. In this paper, we review the evidence on productivity differences and access to resources.

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 sourcebook summarizes the outputs
and lessons of the Livestock in Africa: improving data for
better policies project. It aims to present the challenges
facing professionals collecting and analyzing livestock data
and statistics and possible solutions. While the Sourcebook
does not address all conceivable issues related to enhancing
livestock data and underlining statistical issues, it does
represent a unique document for a number of reasons. To

Changes in climate and their impact on agricultural systems and rural economies are already evident throughout Europe and Central Asia (ECA). Adaptation measures now in use in Moldova, largely piecemeal efforts, will be insufficient to prevent impacts on agricultural production over the coming decades. There is growing interest at country and development partner levels to have a better understanding of the exposure, sensitivities, and impacts of climate change at farm level, and to develop and prioritize adaptation measures to mitigate the adverse consequences.

Ukraine is renowned as the breadbasket
of Europe thanks to its black soils ( Chernozem black
because of the high organic matter content) which offer
exceptional agronomic conditions. One-third of the worldwide
stock of the fertile black soils, which cover more than half
of Ukraine s arable land, a large variety of climatic zones,
and favourable temperature and moisture regimes, offers
attractive conditions for the production of a large range of

Myanmar is an agricultural country. It
is estimated that the agriculture sector represents between
35 to 40 percent of gross domestic product (GDP) and that up
to 70 percent of the labor force (of 32.5 million) is
directly or indirectly engaged in agricultural activities or
depend on agriculture for their income. Given
agriculture's important contribution to the economy,
the modernization of the agriculture sector is a top

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
