Costa Rica's Program of Payments
for Environmental Services (Pago de Servicios Ambientales,
PSA) provides a unique opportunity to evaluate direct
payments as a conservation policy tool. This paper reports
evidence on how much more forest has been conserved in Costa
Rica as a result of PSA contracts with landowners. Such
evidence requires estimating a counterfactual outcome: how
much forest would have been preserved if there had been no

The overarching theme of the book is
development in a land of contrasts. There have been large
economic, social, and political changes. The mass of society
is far more expressive and politically involved today. In
1945, the country had 7.4 million voters, about 11 percent
of the population. Today it has 120 million voters, or 67
percent of the population. The economy has been modernized,
the capitalist ethos spread across regions, mass

Over the past quarter century, Vietnam’s
agricultural sector has made enormous progress. Vietnam’s
performance in terms of agricultural yields, output, and
exports, however, has been more impressive than its gains in
efficiency, farmer welfare, and product quality. Vietnamese
agriculture now sits at a turning point. The agricultural
sector now faces growing domestic competition - from cities,
industry, and services - for labor, land, and water. Rising

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

An extensive review of literature on the
determinants of adoption and impacts of land management
technologies in the Ethiopian highlands was undertaken to
guide policy makers and development agencies in crafting
programs and policies that can better and more effectively
address land degradation in Ethiopia. Several
generalizations emerge from the review: 1) the profitability
of land management technologies is a very important factor

During the Fifth Replenishment Phase of
the Global Environment Facility (GEF-5), portfolio
monitoring and learning review were introduced as key
components of knowledge management in the GEF Secretariat.
These strategies were intended to address the need to
generate knowledge on innovative practices, experiences, and
lessons from projects financed by the GEF. In that regard,
the Land Degradation focal area strategy for GEF-5

Stakeholders' perceptions of
opportunities and constraints to sustainable land management
in Ethiopia was assessed through interviews and a review of
secondary data. Stakeholders included farmers as well as
representatives of development agencies, agricultural
organizations, donors, nongovernmental organizations (NGOs),
and agricultural research systems. Stakeholders generally
perceive that the numerous, well-intentioned but piecemeal

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

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

This study has at its origin the land
question in Paraguay, namely that land ownership is highly
concentrated and has become a source of social conflict in
the rural areas where one-half of the population lives. A
central thesis of the study is that the existing patterns of
land use and ownership, in particular, the very large land
holdings (Zatifundio), are a reflection in part of the
almost insignificant land tax that is charged today on rural

Sri Lanka is in many respects a
development success story. With economic growth averaging
more than 7 percent a year over the past five years on top
of an average growth of 6 percent the preceding five years,
Sri Lanka has made notable strides towards the goals of
ending extreme poverty and promoting shared prosperity (the
‘twin goals’). The national poverty headcount rate declined
from 22.7 to 6.7 percent between 2002 and 2012/13, while

An issue which has generated much
concern has been the potential link between low incomes and
resource degradation. This report presents the results of a
study which investigated this question. Machakos District is
a relatively low income and agriculturally marginal district
in Kenya. Before World War II the colonial administration
was concerned that land degradation was becoming severe
under the pressure of population, aggravated by drought. The
