Recent years have seen mass casualties and severe property damage caused by wildland fires. With increasing housing development in natural-amenity-rich fire-prone areas, human activities not only exert intense pressures on local ecosystems, but also increase difficulties for wildland fire suppression. To cope with wildland fire threats and protect life and property from wildfire, a new California Natural Hazard Disclosure Law (California Civil Code Sec. 1103) went into effect in 1998. Information disclosure required by Sec. 1103 and its related laws is expected to enhance the efficiency of market allocation of land and developments in hazardous areas, making land price and development pattern better reflect the benefit and risk of living in the natural...

Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

In September of 1994, the Army closed the Fort Ord Military Reservation, a Superfund site of some 28,000 acres located in Monterey County, California. Under the Base Closure and Realignment Act, nearly all of this land will be transferred to federal and state entities and to a number of cities of the Monterey peninsula that border the base. A good deal of this property is valuable real estate -- coastal dunes, golf courses, and barracks that can be converted to apartments or dormitories. For the beneficiaries of these property transfers the Fort Ord cleanup is a modern day gold rush that is taking place as part of a Superfund cleanup. What effect have economic development pressures had on the cleanup process and on decisions about cleanup standards? This...

Local governments in the United States use a wide range of tools to preserve rural landscapes. Some of these tools, like the purchase or transfer of development rights, are generally welcomed by farmers and other large landowners. Other tools, like increasing the minimum lot size in a town’s agricultural zone, are more controversial because they are believed to have negative effects on landowner wealth. In this contentious policy environment, it would be useful to know which land use tools actually work to control residential growth, thus achieving the consensual objective of rural preservation. It is reasonable to suppose that large-lot zoning and open space preservation will both reduce the number of homes in a community when it is fully developed....

Uchida, Shinsuke.

Among multiple slippage effects potentially generated in voluntary land retirement programs, this study attempts to identify one unique source of slippage. Specifically, I examine slippage caused by within-a-farm land conversion from uncultivated land to cropland. With the U.S. Agricultural Census farm-level longitudinal data on land use and enrollment in the Conservation Reserve Program (CRP), I find that an average partial-farm CRP participant converts 25% of noncropland to cropping activities as a consequence of CRP enrollment. Also, an estimated slippage rate varies across farm types and regions. In particular, farms with relatively inelastic crop acreage supply lead to more slippage. Knowledge about the mechanisms through which slippage occurs should...

The goal of this work is to investigate land-use change at the global scale over the long run particularly in the context of analyzing the fundamental drivers behind land-use related GHG emissions. For this purpose, we identify the most important drivers of supply and demand for land. On the demand side, we begin with a dynamic general equilibrium (GE) model that predicts economic growth in each region of the world, based on exogenous projections of population, skilled and unskilled labor and technical change. Economy-wide growth is, in turn, translated into consumer demand for specific products using an econometrically estimated, international cross-section, demand system that permits us to predict the pattern of future consumer demands across the...

Incentive-based programs to reduce deforestation are expected to play an increasingly important role in global efforts to protect ecosystems and sequester carbon but their environmental effectiveness is not clear. We investigate program effectiveness and slippage in the context of Mexico's national payments for hydrological services program, which pays private and communal landowners to maintain forest cover on enrolled lands. To measure program impacts, we use matched controls drawn from the program applicant pool to establish counterfactual deforestation rates in the absence of payments. We find statistically significant but small to moderate avoided deforestation impacts. To examine slippage of deforestation to nonenrolled lands, we develop a model of...

Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties. Results show that land use patterns and maize productivity in maize farming systems differ between agroecological zones. The high potential areas experience high maize...

Analyses of the impact of European policies on agricultural change are most often based on agricultural sector models. Such models have their limitations: they cannot specify the interaction between agriculture and the rest of the economy, and their spatial dimension is usually limited. Land use simulation models, on the other hand, usually depend on other models for assessing the demand for land. The consistency of those models with the assumptions and databases of the land use model is often not examined. This article reports on a research project where the links between a macroeconomic model, an agricultural sector model and a land use model were explicitly explored in order to arrive at a consistent model chain. This integrated framework was put to the...

Why Are Farmers Going Multifunctional?

Jongeneel, Roelof A.; Polman, Nico B.P.; Slangen, Louis H.G..

The European farm model is aimed at stimulating and facilitating multifunctional agriculture. This paper presents the results of research into the factors determining the adoption of multifunctional activities. In the paper survey results from 495 farms, spread all over the Netherlands, were used. Binomial logit models were estimated for multifunctional activities in general and four specific activities. Trust in the government is an important explaining factor for participation in nature conservation and recreation, however, less important for services and selling products. Location of the farm is important for nature conservation, services, and recreation. Attitude variables are particularly important for participation in nature conservation and day and...

Agricultural biofuels require the use of scarce land, and this land has opportunity cost. We explore the objective function of a social planner who includes a land constraint in the optimization decision to minimize environmental cost. The results show that emissions should be measured on a per acre basis. Conventional agricultural life cycle assessments for biofuels report carbon emissions on a per gallon basis, thereby ignoring the implications of land scarcity and implicitly assuming an infinite supply of the inputs needed for production. Switchgrass and corn are then modeled as competing alternatives to show how the inclusion of a land constraint can influence life cycle rankings and alter policy conclusions.

Felstehausen, Herman.

Tirana, Albania's capital city, grew rapidly in size and population following 1991 governmental reforms. Before the 1990s, Tirana was a compact city of 225,000 inhabitants. Most properties were state owned. Privatization of land and buildings opened the city to rapid development, heavy traffic, and booming construction of shops, houses, and squatter settlements. Tirana's metropolitan population grew to more than 600,000; city size increased fivefold. This study focuses on land and building claims, both legal and informal, in the context of emerging markets and newly organized land titling and land records systems. A land market action plan supported by the Albanian government, European Union, Land Tenure Center, and others aims to increase tenure security,...

Is agricultural zoning exclusionary?

Gottlieb, Paul D.; Rudel, Thomas; O'Neill, Karen; McDermott, Melanie.

In rapidly suburbanizing areas, minimum lot sizes of ten acres or greater are often used to discourage residential development and to maintain agricultural critical mass. Because of significant development pressure in these places, there is a good chance these lot size regulations will bind. Such “down-zoning” often appears alongside the purchase of agricultural and conservation easements that reduce housing development even more. Whatever the benefits of such policies for agriculture and the environment, they raise obvious concerns about housing supply and affordability. The issue of affordability should be analyzed at the regional scale, since we would normally expect some high-income, low density enclaves to exist within any metropolitan area....

Poverty reduction is one of the overarching objectives of most of Sub-Saharan Africa and other low-income countries. Accordingly, one of IFPRI’s major research themes focuses on policies and strategies for poverty reduction. This research report contributes knowledge to that theme. It also contributes to IFPRI’s ongoing investigation of policies and strategies that foster broad-based and environmentally sustainable agricultural and rural development. In Uganda, where soil erosion and depletion of soil nutrients are widespread, land degradation is a major cause of declining productivity and increasing poverty. In this study, Ephraim Nkonya and his colleagues measure the relative merits of various household income strategies and land management practices in...

A földbirtok-politika választ igénylő kérdései

Major Uses of Land in The United States, 2002

Kapronczai, Istvan.

A kérdések széles területet ölelnek fel, ami folytatható a földvédelemmel, a kör-nyezetvédelemmel, a földadó kérdésével stb. A politikának – kompromisszumokkal és megegyezéssel – mielőbb lépnie kell, mert a rendezett birtokviszonyok növelik a földárat, élénkítik a termőföld iránti keresletet. Az emelkedő árak ugyanakkor bővítik a földkínálatot, végeredményben élénkül az egész földpiac. Ez a leghatékonyabb eszköz a termőfölddel kapcsolatos spekulációk visszaszorítására. Van-e azonban esély a megegyezésre? Politikai síkon aligha! Sőt az agrárközgazdász szakma is meglehetősen megosztott a birtok, a föld kérdésében, hisz körein¬ken belül is hatnak az érdekek, a megcsontosodott előítéletek. Mégis szükség van egy szakmai vitára, egy őszinte véleménycserére,...

This publication presents the results of the latest (2002) inventory of U.S. major land uses, drawing on data from the Census, public land management and conservation agencies, and other sources. The data are synthesized by State to calculate the use of several broad classes and subclasses of agricultural and nonagricultural land over time. The United States has a total land area of nearly 2.3 billion acres. Major uses in 2002 were forest-use land, 651 million acres (28.8 percent); grassland pasture and range land, 587 million acres (25.9 percent); cropland, 442 million acres (19.5 percent); special uses (primarily parks and wildlife areas), 297 million acres (13.1 percent); miscellaneous other uses, 228 million acres (10.1 percent); and urban land, 60...
