Purchasing development rights is a major mechanism for the protection of environmental quality and landscape amenities. This paper provides a targeting strategy for protecting multiple environmental benefits that takes into account land costs and probability of land use conversion. We compare two strategies. Subject to a budget constraint on parcel purchases, the standard strategy is to target parcels with the highest ratio of environmental benefits to land costs. The standard strategy selects parcels even if there is little probability that the parcel would otherwise be converted.

The paper looks at the development of conservation policy since the mid-20th Century. It reviews how land conservation policy developed in the UK, and the ethical and policy design issues which emerged as the focus of conservation expanded. It then considers how the lessons learned may be applied to address environmental conservation needs in developing society situations. The first steps in UK conservation policy entailed legislation to establish public rights over privately owned resources.

In many parts of the world, deteriorating environmental conditions have led policy makers to develop policies and programs aimed at promoting conservation practices on lands devoted to agriculture. Such programs have been studied by environmental economists, but little research has been done on the usefulness of strategically varying the conservation contract's length.

Temporal spillovers occur when a conservation program changes what happens to land outside the temporal window of the conservation contract. This may happen when conservation improves land so that returns to non-conservation uses are increased, or when landowners' preferences become more pro-conservation as they see land flourish under conservation, for example. These post-contract changes may occur on the extensive margin (acres of land conserved) or intensive margin (intensity of land in a given use).

Until recently public efforts to encourage conservation on private land in many countries has primarily been through uniform payment policies. Auctions are increasingly used as a payment mechanism to acquire public benefits such as conservation actions that provide environmental improvements on private land (e.g. the US Conservation Reserve Program (CRP).

"Green Bonds" emerged as a new form of environmental financing in 2007. While most investors still view them as a niche product in the overall fixed income market, green bonds have grown rapidly to nearly $37 billion in issuance in 2014, with issuers from the World Bank to the State of Massachusetts. This paper examines the current and potential future use of green bonds for financing sustainable land use and conservation projects around the world.

The size of the protected area is recognized as one of the key attributes for assessing the effectiveness of investing in protected areas. We evaluate the effectiveness of protected areas by examining economies of scale in size and the average cost of acquiring protected areas depending on the land acquisition contract types and motivations. We use recent land acquisitions (2000-2009) of the central and southern Appalachian forest ecosystems by The Nature Conservancy (TNC) as a case study.

This special issue of Policy Matters focuses on the outreach and impact of Dr. Elinor Ostrom's groundbreaking research on common property (or commons) theory. Her work was instrumental in shaping contemporary analyses of resource management and conservation, especially at a local level. This collection of research papers, essays, commentaries, and songs build upon her work and provide case studies demonstrating the practical application of her theoretical contributions. 

Climate warming and human actions both have negative impacts on the land cover of Mongolia, and are accelerating land degradation. Anthropogenic factors which intensify the land degradation process include mining, road erosion, overgrazing, agriculture soil erosion, and soil pollution, which all have direct impacts on the environment. In 2009–2010, eroded mining land in Mongolia increased by 3,984.46 ha., with an expansion in surrounding road erosion. By rough estimation, transportation eroded 1.5 million ha. of land.

We examined the preferences for wetland conservation among urban and rural dwellers in Malaysia. A choice experiment using face-to-face interviews with urban and rural households was employed. Wetland conservation alternatives were described in terms of environmental protection zones, biodiversity protection, recreational services and flood. Each alternative was connected to a cost for the household, which was a reduction in subsidies for daily goods. Using a latent class model, we identified three groups with distinctly different preferences.
