INVESTIGATING THE ECONOMIC AND WATER QUALITY EFFECTS OF THE 2003 CAP REFORM ON ARABLE CROPPING SYSTEMS: A SCOTTISH CASE STUDY AgEcon
Mouratiadou, Ioanna; Russell, Graham; Topp, Cairistiona; Louhichi, Kamel.
The 2003 Common Agricultural Policy Reform aimed to promote the socio-economic and environmental sustainability of agricultural systems. An important question is how far the Reform has indeed encouraged farmers to contribute to achieving broad economic and environmental goals. The economic and water resource effects of the Reform have been explored for the case study area of the Lunan catchment, which is typical of Scottish arable cropping areas. Land use data analysis, bio-physical modelling and bio-economic modelling were used in combination to identify the effects of a range of scenarios. The results indicate only small changes in the cropping pattern and associated economic and water quality indicators as a result of the Reform, with the main changes...

Is agricultural zoning exclusionary? AgEcon
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....

Hegyi, Judit; Kacz, Karoly; Kettinger, Anita.
In the course of a survey we’ve researched private farms of the West-Transdanubian Region in terms of their land area, economic farm size, land use and types of their enterprise. The research of agricultural enterprises from these points of view was the further share of our work. 371 pieces of questionnaire were sent farms of enterprises (joint-stock company, ltd., deposit company, co-operative) in Gyôr-Moson-Sopron, Vas and Zala counties, from which 72 assessable documents returned. The questionnaire asked the farmers the type of their farming (according to the rate of Standard Gross Margin), their economic farm size and data of land property and land use (in the year of 2002, 2004 and 2006). It also enquired about the claim to change of land size, the...

Land use and Coastal Management in the third Countries; Egypt as a case OceanDocs
Hamza, W..
Although the aspects of both land use and coastal management represent part of the larger concept of sustainable development, the strength and interest with which these aspects are received varies considerably among countries. It is well known that land use planning can facilitate the allocation of land to those use(s) that provide the greatest sustainable benefits. However, in order to achieve a sustainable land use planning, an in-depth analysis of the existing resources is required (e.g. localization, features, sensitivity to development). Furthermore, the understanding of development characteristics (resource needs and collateral efforts), would make it possible to identify the use of natural resources. In that regard Sense and Toccolini (1998)...

Land use and land reform in former Central and East European countries AgEcon
Takacs-Gyorgy, Katalin; Bandlerova, Anna; Sadowski, Adam.
The importance of agriculture is decreasing all over the world. The aim of the paper is to compare the ownership structure and land use in some selected former Central and Eastern European countries. The property structure and land use is in dichotomy, the production is performed simultaneously on small-size farms which produce primarily for self-consumption. The importance of farm land leases is increasing. The present paper tries to identify the main differences and similarities in land ownership and property structure, the changes in the last fifteen years, what happened and whether the expectations had been met. Furthermore the paper compares the main regulations of land ownership and tenancy in different countries, explains land market protection, and...

Land Use and Remedy Selection: Experience from the Field - The Fort Ord Site AgEcon
Wernstedt, Kris; Hersh, Robert.
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...

Land Use Change and Ecosystem Valuation in North Georgia AgEcon
Ngugi, Daniel; Mullen, Jeffrey D.; Bergstrom, John C..
This study seeks to forecast land use change in a North Georgia ecosystem, and estimate the economic value of the ecosystem using benefit transfer techniques. We forecast land use change based on a structural time series model and a simple growth rate model. The study suggests a lower bound willingness to pay value of about USD 16,000 per year to ensure compliance with fishing and drinking water quality standards with regard to fecal coliform bacteria and dissolved oxygen. Conservation efforts are likely to cost less than the cost of defensive behavior or ecosystem restoration.

Land Use Change and Ecosystem Valuation in North Georgia AgEcon
Ngugi, Daniel; Mullen, Jeffrey D.; Bergstrom, John C..
A model of land allocation at the aggregate watershed level was developed assuming profit/net benefit maximization under risk neutrality. The econometric land use model was analyzed as an equation by equation SURE model as all the independent variables were the same for both equations. In analyzing effect of land use change on water quality, we took year 2005 as our baseline and postulated three land use scenarios. We applied Benefit Transfer techniques to value water quality changes resulting from land use change and estimated lower bounds for WTP to improve water quality to meet the FCB criterion for drinking water supply and fishing waters and BOD (DO) criteria for fishing waters. Water quality modeling revealed that land use change would result in...

Land use change in the Atlantic Forest affects carbon and nitrogen sources of streams as revealed by the isotopic composition of terrestrial invertebrates Biota Neotropica
Augusto,Fernanda Gaudio; Tassoni Filho,Mauricio; Ferreira,Anderson; Pereira,Alexandre Leandro; Camargo,Plínio Barbosa de; Martinelli,Luiz Antonio.
Terrestrial invertebrates link terrestrial systems to aquatic ones, making vegetal material produced in the watershed available to aquatic food webs. In this study, using carbon and nitrogen stable isotopes, we evaluated the importance of introduced C4 grasses as a source of carbon in aquatic food webs of headwater streams of the coastal Atlantic Forest located on the north coast of the State of São Paulo, in the southeastern region of Brazil. Terrestrial invertebrates were collected in two streams: one where the main land cover was pristine montane Atlantic Forest (forest stream) and another where the main land cover was introduced C4 forage grasses for livestock (pasture stream). The average δ13C of terrestrial invertebrates collected in the forest...

Land Use Consequences of Crop Insurance Subsidies AgEcon
Miao, Ruiqing; Feng, Hongli; Hennessy, David A..
There have long been concerns that federal crop insurance subsidies may significantly impact land use decisions. It is well known that classical insurance market information asymmetry problems can lead to a social excess of risky land entering crop production. Our conceptual model shows that the problem will arise absent any information failures. This is because the subsidy is i) proportional to acres planted, and ii) greatest for the most production risky land. Using farm-level data, we follow this observation through to establish the implications of subsidies for the extent of crop production, with particular emphasis on U.S. regions where the cropland growth is likely to have marked adverse environmental impacts. Simulation results show that when...

Land use drives change in amazonian tree species Anais da ABC (AABC)
VIEIRA,IMA CÉLIA G..
Abstract: The Amazonian rainforest has been subjected to exceptionally high rates of land use change (LUC), primarily for pasture. We present here an analysis of the impact of LUC on trees from studies made in Pará state. LUC results in drastic declines in native species richness, changes species composition and impacts community resilience and ecosystem services provided by the Amazonian rainforest. Given that secondary forests are expanding in Amazonia we argue that this regrowth forest should be taken into account when planning conservation in this region.

Land use in Kenya OceanDocs
This book exposes the key land use and environmental problems facing Kenya today due to lack of an appropriate national land use policy. The publication details how the air is increasingly being polluted, the water systems are diminishing in quantity and deteriorating in quality. The desertification process threatens the land and its cover. The soils are being eroded leading to siltation of the ocean and lakes. The forests are being depleted with impunity thus destroying the water catchments. The savannas and grasslands are undergoing de-vegetation through overgrazing, charcoal burning and other poor land use practices leading to desertification. The book also reveals the underlying causes of the deterioration of the life support systems (air, water and...

Land Use Issues: The Last Settler’s Syndrome AgEcon
Groothuis, Peter A..
In the last settler’s syndrome, each new settler wants the area to remain as it was on their arrival. Newcomers’ preferences often differ from long-term residents, and conflicts arise. To explore land use issues among various groups, a survey of opinions on mountain views was developed and administered to Watauga County residents in western North Carolina. Watauga County provides an interesting case study, because it is a growing area with an influx of newcomers along with long-time residents. The results suggest that agreements can be achieved on some land use issues, whereas disagreements will arise on others.

Landowner response to policies regulating land improvements: lease or search for other options? AgEcon
Eija, Pouta; Sami, Myyra; Kyosti, Pietola.
Land improvements with long pay-back periods are often delayed on leased agricultural land, resulting in social costs through land degradation, decreased land productivity and environmental problems. An important question is thus how landowners would respond to regulations and mandates concerning land improvements. Based on a landowner survey, we analyse landowner choices under certain land improvement regulations, using the currently dominant choice of leasing land for agricultural use as the benchmark. The results indicated that land leasing will continue to increase in the future, but if the landowner mandate to co-finance costly land improvements is increased, landowners are predicted to respond significantly to these mandates and search for other land...
