The purpose of this report is to improve
the knowledge base for facilitating investments in land
management technologies that sequester soil organic carbon.
While there are many studies on soil carbon sequestration,
there is no single unifying volume that synthesizes
knowledge on the impact of different land management
practices on soil carbon sequestration rates across the
world. A meta-analysis was carried out to provide soil

This book is organized as follows: this
first chapter examines the pattern of structural
transformation in Middle East and North Africa, or MENA and
summarizes the role of various factors examined thoroughly
in the rest of the volume. This second chapter examines the
correlates of this overall disappointing performance. At the
macro level, MENA countries have been unable to maintain
depreciated (undervalued) real exchange rates for long

The forces unleashed by the Arab
political awakening have the power to be transformational.
One critical parameter of success will be whether the Arab
political awakening is accompanied by a concurrent economic
awakening. Economic integration through increased trade and
foreign direct investment (FDI) is one key means available
in the short to medium term to policy makers to put the
Partnership countries on a higher path of sustainable

"Getting the prices right" is
a good starting point but is not sufficient for achieving
environmentally efficient outcomes. Other policy
interventions are often necessary to complement pricing
policies. Moreover, when pricing is not at all feasible,
regulatory and command-and-control policies must be used
instead. This paper focuses on three interrelated themes at
the core of the pricing problem. First, there is the

The work described in this report is a
first step to addressing the longer-term issues related to
the competitiveness of South Sudan's farmers in a
regional context. It focuses on the options for increasing
the amount and value of agricultural production in the crop
sector, the potential contribution of rural roads to
increasing crop production and how to sequence and
prioritize rural road investments in a way that maximizes

Zambia is endowed with an abundance of
natural resources that include, water, forests and wildlife.
The country's wildlife resources are managed through
government-supported National Parks and Game Management
Areas (GMAs) and private sector game ranches. The main
objective of this wildlife sector policy review is to
consolidate the findings collected from an extensive
bibliography published during the life of the current

Recent global initiatives on debt relief
and development assistance call for increasing aid for trade
to the poorest countries. The paper applies a multi-country
computable general equilibrium model to measure the
effectiveness of alternative aid for trade categories. The
findings show that aid for trade policies expand trade and
alleviate international income inequalities in the recipient
countries, that will benefit mainly from aid for trade

Argentina is one of the world's
largest biodiesel producers and the largest exporter, using
soybeans as feedstock. Using a computable general
equilibrium model that explicitly represents the biofuel
industry, this study carries out several simulations on two
sets of issues: (i) international markets for biofuel and
feedstock, such as an increase in prices of soybean, soybean
oil, and biodiesel, and (ii) domestic policies related to

The future development of the Tajik
economy will be shaped by its comparative advantage on world
markets. Exploiting comparative advantage enables an economy
to reap gains from trade. Tajikistan's most important
comparative advantage is its hydropower potential, which is
far larger than the economy's domestic requirements.
Yet, high capital costs of building hydropower plants and
the unstable geopolitical situation in the transit region to

The objectives of the study are to
assess the impact of operational efforts in farmland
restructuring and sustainable agricultural land management
on vulnerability amongst rural households in Tajikistan; and
to provide context and improve strategies for current
operations in land reform, rural growth and sustainable land
management given the challenges of economic transition,
institutional, economic and environmental fragility, and the

This AQUASTAT report presents the most recent information available on water resources and their use in the 22 countries in the Southern and Eastern Asia region. Clearly it has an emphasis on agricultural water use and management. But in addition it contains the relevant tables and maps, and a regional synopsis emphasizing the particular characteristics of this large and diverse region. It also analyses the changes that have occurred since the first survey in 1999.
