THE EFFECTS OF CAP REFORM ON THE PERIURBAN AGRICULTURAL AREA IN THE PLAIN OF THE CITY OF ASSISI (CENTRAL ITALY) AgEcon
Torquati, Biancamaria; Giacche, Giulia; Taglioni, Chiara; Musotti, Francesco.
In periurban areas agriculture can assume a multifunctional role that includes landscape conservation, sustainable resource management, biodiversity conservation, leisure activities, and can also maintain adequate conditions in densely populated areas for a safe and habitable environment. This study investigates the effects of the introduction of single farm payment on the periurban agricultural area in the plain of the City of Assisi, an area with a strong landscape value. A survey was carried out to determine: changes in production, changes on farm incomes, structural adjustments, the level of multifunctionality of periurban agriculture. Moreover, a survey of 355 residents was made to assess their willingness to pay for some positive externalities of the...

The Economic Valuation of Marine Ecosystems AgEcon
Nunes, Paulo A.L.D.; Ding, Helen; Markandya, Anil.
In a democratic system, policy makers have to take the preferences of the citizens into account. Since we live in a world with scarce resources, one is asked to make choices regarding the use and management of these resources. In this context, if policy makers decide to invest in the protection of marine ecosystems, less financial resources will be available for other policy areas, for example national health. Moreover, the investment in the protection of marine ecosystems brings along with it the provision of a wide range of benefits to humans though most are not priced in the existing markets – for example climate regulation and provision of habitat for biodiversity. Given that most human activities are priced in one way or other, in some decision...

European Forests and Carbon Sequestration Services: An Economic Assessment of Climate Change Impacts AgEcon
Ding, Helen; Nunes, Paulo A.L.D.; Teelucksingh, Sonja S..
This paper reports an original economic valuation of the impact of climate change on the provision of forest regulating services in Europe. To the authors’ knowledge the current paper represents the first systematic attempt to estimate human well-being losses with respect to changes in biodiversity and forest regulating services that are directly driven by climate change. First, selected 34 European countries are grouped by their latitude intervals to capture the differentiated regional effects of forests in response to climate change. Moreover, the future trends of forest areas and stocked carbon in 2050 are projected through the construction and simulation of global circulation models such as HADMC3 following four different future developing paths...

The Economic Value of Wetland Conservation and Creation: A Meta-Analysis AgEcon
Ghermandi, Andrea; van den Bergh, Jeroen C.J.M.; Brander, Luke M.; de Groot, Henri L.F.; Nunes, Paulo A.L.D..
The rationale for conservation and creation of wetlands stems from the recognition of both their ecological and economic values. This paper examines the welfare impacts of goods and services provided by wetlands. We collected 385 estimates of the economic value of 181 natural and man-made wetlands from 167 studies worldwide. The resulting database is less biased towards North America than previous reviews of the literature. The relative importance of characteristics of the valuation study, of the wetland site, and of the socio-economic and geographical context is estimated by means of a meta-regression analysis of wetland values. Provision of amenities, flood control and storm buffering, and water quality improvement are the most highly valued wetland...
