Land use change for flood protection - a prospective study for the restoration of the river Jelašnica watershed [Serbia]

Policy Papers & Briefs
Dezembro, 2011
Sérvia

Serbia’s hilly-mountainous regions are extremely vulnerable to flooding as a consequence of their natural characteristics and human impacts. Land mismanagement influences the development of erosion processes, and causes soil degradation that significantly reduces the land’s capacity to infiltrate and retain rainwater. Inappropriate land use as well as development activities replace permeable with impervious surfaces in the watershed. This leads to more rapid runoff generation and the more frequent appearance of torrential floods and bed-load deposits on downstream sections.

Long-term fragmentation dynamics in semi-natural forest landscape

Policy Papers & Briefs
Dezembro, 2014
Letónia

Study was conducted in north-eastern Latvia (57° 38’ N, 22° 17’ E): in a part of Slitere National Park that was un-managed since year 1923 and affected by large storm in November of 1969. Supervised classification of Corona and Landsat 5 images of the area (in total 1646 ha) from years before and after the storm (1966–2010) were carried out and parameters characterizing the fragmentation calculated for 3 land-cover classes: forest, areas with low woody biomass and non-forest areas.

COUNTY LEVEL TAXABLE AGRICULTURAL LAND VALUES IN NORTH DAKOTA: COMPARING THE GROSS REVENUE APPROACH WITH VALUES BASED ON RENTAL VALUES

Policy Papers & Briefs
Dezembro, 2002

Land values calculated with the current North Dakota agricultural land valuation model were compared with values calculated by capitalizing the average cash rent for each county. Results showed there was a significant difference in cropland values, but there was no significant difference in non-cropland values. Land values for the 2000, 2001, and 2002 assessments were compared.

Dezembro, 1998
Filipinas

A dynamic model of deforestation and agricultural expansion in the Philippines is developed to elucidate the economic factors driving current land use trends and determine the efficacy of prevailing public forest management regulations. Optimization results are interpreted to show potential gains and intervention areas to improved national forest resource management.

A Conjoint Analysis of Public Preferences for Agricultural Land Preservation

Journal Articles & Books
Outubro, 2004

Public preferences for the nonmarket services of permanently preserved agricultural land are measured and compared using conjoint analysis. The results from a survey of 199 Delawareans suggest environmental and nonmarket-agricultural services are the most important preserved-land attributes. Results also suggest that open space associated with wetlands on farms is neither an amenity nor a disamenity. On the margin, preserved parcels with agricultural and environmental attributes provide net benefits, which may exceed $1,000,000 for a 1,000-acre parcel.
