Declining soil fertility due to
inadequate farming practices, deforestation and overgrazing
are among the primary impediments to increased agricultural
productivity in Sub-Saharan Africa. These causal factors,
driven by social, economic and political forces, manifest
themselves in market, policy and institutional failures,
inappropriate technologies and practices. This is also the
case in Tanzania where over 90 percent of the population is

In India, land continues to be of
enormous economic, social, and symbolic relevance. The way
in which land can be accessed and its ownership documented
is at the core of the livelihood of the large majority of
the poor, especially in rural and tribal areas and
determines the extent to which increasingly scarce natural
resources are managed. Land policies and administration are
critical determinants of the transaction cost associated

The pattern of global land use has
important implications for the world's food and timber
supplies, bioenergy, biodiversity and other eco-system
services. However, the productivity of this resource is
critically dependent on the world's climate, as well as
investments in, and dissemination of improved technology.
This creates massive uncertainty about future land use
requirements which compound the challenge faced by

The growing use of Payments for
Environmental Services (PES) for conservation has fostered a
debate on its effectiveness, but the few efforts to date to
assess the impact of PES programs have been hampered by lack
of data, leading to very divergent results. This paper uses
data from a PES mechanism implemented in Quindío, Colombia,
to examine the impact of PES on land use change. Alone among
all early PES initiatives, the Silvopastoral Project

In India, land continues to be of
enormous economic, social, and symbolic relevance. The main
purpose of this report is to review new empirical evidence
on land administration and land policy, as well as the
possible interaction between the two, to derive policy
conclusions. The empirical basis for the discussion of land
administration is provided by a review of land records,
survey and settlement, and land registration in 14 states.

In the 1980s the Thai government tried to legalize squatters by issuing special titles that restricted the sale and rental of the land. Using data from 2,874 farming households collected in 1997, the author finds that in places where these government titles where issued, leased plots are more likely to be titled than those that are self-cultivated. For these areas, he uses a model to estimate a 6 percent risk premium in the rental rate for untitled plots.

Livestock systems globally are changing
rapidly in response to human population growth,
urbanization, and growing incomes. This paper discusses the
linkages between burgeoning demand for livestock products,
growth in livestock production, and the impacts this may
have on natural resources, and how these may both affect and
be affected by climate change in the coming decades. Water
and land scarcity will increasingly have the potential to

China has undergone a profound economic and social transformation as it moves from a centrally-planned to a market-oriented economy. Land issues are implicated in this ongoing transformation in numerous important ways - as key factors in China's quest for economic growth, national food security and social stability; as important influences in the rapid growth of China's cities as well as the future of its agriculture; and as central features in local government finance and in the growth and stability of the financial and banking sector.

This report summarizes the findings of
the Uganda Sustainable Land Management Public Expenditure
Review (SLM PER). The SLM PER was undertaken to achieve six
main objectives: (i) establish a robust data base on
SLM-related public expenditure that can support credible
empirical analysis; (ii) develop a sound methodology for
conducting SLM PERs, which could guide similar work in the
future; (iii) analyze the level and composition of SLM

The question of whether biofuels help
mitigate climate change has attracted much debate in the
literature. Using a global computable general equilibrium
model that explicitly represents land-use change impacts due
to the expansion of biofuels, this study attempts to shed
some light on this question. The study shows that if biofuel
mandates and targets currently announced by more than 40
countries around the world are implemented by 2020 using

This study analyzes the long-term
impacts of large-scale expansion of biofuels on land-use
change, food supply and prices, and the overall economy in
various countries or regions using a global computable
general equilibrium model, augmented by a land-use module
and detailed representation of biofuel sectors. The study
finds that an expansion of global biofuel production to meet
currently articulated or even higher national targets in

Characterization of preexisting flora is an essential preliminary step for successful land rehabilitation projects. This descriptive study was undertaken in a fragmented, dry tropical forest region in Panama. Five different habitat types were selected: active pasture, 2-yr and 5-yr abandoned pastures, forested riparian zones, and a forest fragment. Species richness, density, basal area, dispersal modes, and phenology of trees as well as their uses were determined.
