The 2007-2008 upsurge in agricultural
commodity prices gave rise to widespread concern about
investors causing a "global land rush". Large land
deals can provide opportunities for better access to
capital, transfer of technology, and advances in
productivity and employment generation. But they carry risks
of dispossession and loss of livelihoods, corruption,
deterioration in local food security, environmental damage,

Economic, agronomic, and biophysical
drivers affect global land use, so all three influences need
to be considered in evaluating economically optimal
allocations of the world's land resources. A dynamic,
forward-looking optimization framework applied over the
course of the coming century shows that although some
deforestation is optimal in the near term, in the absence of
climate change regulation, the desirability of further

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

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

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

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

A rainforest can be modeled as a dynamic
asset subject to various risks, including risk of fire. Any
small part of the forest can be in one of two states: either
untouched by forest fire, or already damaged by fire, in
which case there is both a local forest loss and increased
dryness over a broader area. In this paper, two Bellman
equations are constructed, one for unharmed forest and a
second for already burnt forest. The analysis solves the two

The case for climate action has never
been stronger. Current weather extremes, including storms,
floods and drought, affect millions of people across the
world. Climate change is putting water security at risk;
threatening agricultural and other supply chains as well as
many coastal cities. The likelihood of severe pervasive and
irreversible impacts will grow without action to limit and
reverse the growth of GHG emissions globally. Last year’s

The country’s forest areas occupy 21.7
million ha (approximately 27.6 percent of its total surface
area), and are inhabited by close to 10 percent of its total
population. The forest sector generates a variety of timber
and non-timber products and eco-services. The Turkish
government has put great effort into reforestation and
forest management, increasing the total area of forests. In
their tenth national development plan (2014-2018), the
