Kenya’s hurried pursuit of infrastructure developments in the last decade has highlighted the need for effective environmental regulation surrounding the approval, construction and operation of new projects. One such project, the Nairobi-Thika Highway Improvement Project (NTHIP), creates fertile ground for investigation into how well Kenya’s environmental safeguards work. Transforming the road from Nairobi to Thika town into a super highway is one of Kenya’s first large-scale transportation infrastructure projects.

Karol Boudreaux has recently penned this article, Addressing Land Rights Can Make Social Change Possible for the Guardian. USAID is delighted to see an important foundation taking a public and carefully articulated stand on this vital development subject. Ms. Boudreaux correctly notes "The challenge is to expand people's opportunity to improve their lives by securing their property rights." This is indeed one of the most fundamental objectives in addressing challenges related to property rights.

The New York Times reported that Greece’s land administration system is a major impediment to economic growth. After a history of occupations, wars, and shifting population centers, less than 7 percent of the country has been properly mapped, while most land transaction records are handwritten and lack clear boundaries or zoning. Property ownership is often unclear, especially in rural areas, and that has led to competing claims for property and a backlog of court cases.

The vast majority of Liberian citizens – those living in rural communities – are on a path toward having customary land ownership rights recognized for the first time in Liberia’s history. A major milestone in Liberia’s lengthy land tenure reform process was reached on May 21 when the Liberian Land Commission presented President Ellen Johnson Sirleaf with the country’s first-ever Land Rights Policy, which defines Public Land, Government Land, Customary Land, and Private Land, as well as Protected Areas that will be conserved for the benefit of all Liberians.

Urban transportation externalities are a key development challenge. Based on the existing literature, the authors illustrate the magnitudes of various external costs, review response policies, and measure and discuss their selection, particularly focusing on the context of developing countries. They find that regulatory policy instruments aimed at reducing local air pollution have been introduced in most countries in the world. On the other hand, fiscal policy instruments aimed at reducing congestion or greenhouse gas emissions are limited mainly to industrialized economies.

On May 17, Liberian President and Nobel Peace Prize winner Ellen Johnson Sirleaf will discuss her administration’s goals, her perspective on land rights and land tenure security, and some of the challenges facing Liberia at a Thomson Reuters Newsmaker in Washington DC. A live stream of the event will be available at 2:30 p.m. EDT on May 17.

Should polio be eradicated worldwide, countries must decide whether to continue to
vaccinate with the live-attenuated vaccine, to continue to vaccinate with the alternative,
killed vaccine, or to cease vaccinating. To reap a dividend from polio eradication,
countries must choose the last option, but vaccination cessation entails interdependent
risks as well as rewards. This article models the polio vaccination cessation game,
deriving the conditions that support vaccination cessation as an equilibrium, describing

With the aim of promoting national food security, the Vietnamese government enforces the designation of around 35 per cent of agricultural land strictly for paddy rice cultivation. We investigate the economic effects of adjusting this policy, using an economy-wide model of Vietnam with detailed modelling of region-specific land use, agricultural activity, poverty and food security measures.

Strengthening women’s rights to own and inherit property provides them with greater opportunities to generate income and exercise control over family resources, which can improve women’s ability to feed and educate their children. This simple but powerful message is highlighted by Deborah Espinosa’s recent Huffington Post blog In Kenya, Land Rights Bring New Hope for Women and Girls. Espinosa is a senior attorney and land tenure specialist at Landesa, which implements USAID’s Kenya Justice project.

As countries increasingly strive to transform their economies from agriculture‐based into a diversified one, land rental will become of greater importance. It will thus be critical to complement research on the efficiency of specific land rental arrangements such as sharecropping with an inquiry into the broader productivity impacts of the land rental market. Plot‐level data for a matched landlord–tenant sample in an environment where sharecropping dominates allow us to explore both issues.

Global climate change cannot be addressed effectively through Reducing Emissions from Deforestation and Forest Degradation (REDD+) without addressing land tenure and property rights systems. Critics of REDD+ initiatives fear that it could undermine indigenous and local claims as national governments enforce their central authority over forests.

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.
