The complex relationships between governance processes, ecosystem management and biodiversity conservation are receiving growing
attention by the scientific community. The scope of research in this field is generally that of identifying main governance
factors leading to success or failure in the sustainable management of ecosystems and biodiversity conservation, so to develop
appropriate sectoral and intersectoral policies fostering sustainable use of natural resources. In this paper, a methodological
approach is first presented and then applied to analyse the impacts of agriculture and rural policies on agro-ecosystem services
and biodiversity conservation in the central hills of Tuscany, the Chianti area. This approach is focusing in particular on
governance objectives and instruments used in the management of ecosystem services. A share-farming system based on multifunctional
agriculture ruled Chianti until World War II. Then, after the abandonment of rural areas by share-farmers, governance objectives
and ecosystem management were oriented towards the production of commodities such as wine and olive oil almost ignoring the
provision of public goods such as soil erosion and water run-off control and biodiversity conservation. In order to achieve
a more sustainable ecosystems management in Chianti, there is the need to develop a multifaceted governance strategy to reward
appropriately the supplying of environmental goods and services by farmers. 相似文献

In this work, ash generated by the combustion of wood in a central heating plant was used to remove and permanently store by accelerated carbonation CO2 contained in a gas mixture simulating biogas. The process was studied as an alternative treatment to the ones currently available on the market for biogas upgrading. The process was investigated at laboratory scale by setting up a facility for directly contacting the wood ash and the synthetic biogas in a fixed bed reactor. The process was able to completely remove CO2 during its initial phase. After about 30 h, CO2 started to appear again in the outlet stream and its concentration rapidly increased. The specific CO2 uptake achieved in solid carbonate form was of about 200 g/kg of dry wood ash. This value is an order of magnitude higher than the ones found for waste incineration bottom ash carrying out similar experiments. The difference was ascribed to the physicochemical properties of the ash, characterized by a fine particle size (d50 <?0.2 mm) and high content of reactive phases with CO2 (e.g., Ca hydroxides). The leaching behavior of the wood ash was examined before and after the accelerated carbonation process showing that the release of several elements was lower after the treatment; Ba leaching in particular decreased by over two orders of magnitude. However, the release of the critical elements for the management of this type of residues (especially Cr and sulfates) appeared not to be significantly affected, while V leaching increased. 相似文献

Stomatal ozone uptake, determined with the Jarvis' approach, was related to photosynthetic efficiency assessed by chlorophyll fluorescence and reflectance measurements in open-top chamber experiments on Phaseolus vulgaris. The effects of O3 exposure were also evaluated in terms of visible and microscopical leaf injury and plant productivity. Results showed that microscopical leaf symptoms, assessed as cell death and H2O2 accumulation, preceded by 3-4 days the appearance of visible symptoms. An effective dose of ozone stomatal flux for visible leaf damages was found around 1.33 mmol O3 m−2. Significant linear dose-response relationships were obtained between accumulated fluxes and optical indices (PRI, NDI, ΔF/Fm′). The negative effects on photosynthesis reduced plant productivity, affecting the number of pods and seeds, but not seed weight. These results, besides contributing to the development of a flux-based ozone risk assessment for crops in Europe, highlight the potentiality of reflectance measurements for the early detection of ozone stress. 相似文献

This paper focuses on appropriation of natural capital through construction of buildings. The ecological footprint and the Costanza natural capital concepts are applied. The environmental consequences of human settlement are currently of great concern, and a need is felt to reduce the impact of building on the environment. The embodied energy of building materials and the "land area" required to sustain their production are considered to evaluate the demand on nature of this activity. The ecological footprints of 2 typical Italian buildings are compared. The paper also focuses on how to reduce the natural capital appropriation of building construction by means of environmentally inexpensive materials, renewable energy resources, and optimization of the use of bioproductive land by construction of multistoried buildings. Finally, to allocate an environmental load of buildings, an economic evaluation of natural capital appropriation through building construction is proposed. 相似文献

This research proposes an integrated framework to investigate human-dominated systems and provide a basic approach to urban
and regional studies in which the multiple interactions between economic and ecological processes are considered as a whole.
Humans generate patterns of land use, infrastructures and other settings and redistribute ecosystem functions as flows of
energy and matter for self-maintenance. To understand these emerging interactions between humans and ecological processes,
human activities (e.g. transformation processes, land conversions, use of resources) and biophysical agents such as geomorphology,
climate and natural cycles need to be considered. Emergy Analysis (spelled with an “m”) is then used as an environmental accounting
method to evaluate different categories of resource use with reference to their environmental cost. A case study of the Province
of Cagliari (in the island of Sardinia, Italy) is reported and the procedure for allocating emergy flows, assigning them to
districts and managing point data is discussed. Outcomes plotted on a map showed non-homogeneous spatial distribution of emergy
flows throughout the region, suggesting the way ecosystem functions are affected and restructured by the human economy. 相似文献

An evaluation of the air quality based on the combined use of monitoring data, dynamic emission inventories, and three-dimensional
modeling has been performed in an area in North West Italy. Yearly maps of the pollutants of most concern have been produced
by means of an Eulerian modeling system, run for two nested domains. The system is based on MINERVE diagnostic meteorological
model, TREFIC (TRaffic Emission Factors Improved Calculation) traffic emission module, and farm air quality regional chemical-transport
model. The zooming approach has allowed to correctly reproduce local concentrations in the small urban area in the inner domain
as well as to quantify the role played by selected local sources respect to distant ones. The study of the impact of the future
car fleet, pointing out the expected improvement for nitrogen oxides and the persisting problem of PM, provides a rationale
for air quality governance. 相似文献

We analyze longtime series of annual snout positions of several valley glaciers in the northwestern Italian Alps, together with a high-resolution gridded dataset of temperature and precipitation available for the last 50 years. Glacier snout fluctuations are on average negative during this time span, albeit with a period of glacier advance between about 1970 and 1990. To determine which climatic variables best correlate with glacier snout fluctuations, we consider a large set of seasonal predictors, based on our climatic dataset, and determine the most significant drivers by a stepwise regression technique. This in-depth screening indicates that the average glacier snout fluctuations strongly respond to summer temperature and winter precipitation variations, with a delay of 5 and 10 year, respectively. Snout fluctuations display also a significant (albeit weak) response to concurrent (same year) spring temperature and precipitation conditions. A linear regressive model based on these four climatic variables explains up to 93 % of the variance, which becomes 89 % when only the two delayed variables are taken into account. When employed for out-of-sample projections, the empirical model displays high prediction skill, and it is thus used to estimate the average glacier response to different climate change scenarios (RCP4.5, RCP8.5, A1B), using both global and regional climate models. In all cases, glacier snout fluctuations display a negative trend, and the glaciers of this region display an accelerated retreat, leading to a further regression of the snout position. By 2050, the retreat is estimated to be between about 300 and 400 m with respect to the current position. Glacier regression is more intense for the RCP8.5 and A1B scenarios, as it could be expected from the higher severity of these emission pathways. 相似文献

To investigate whether the specificities of real jobs create distinctions in the performance of workers in different motor tests for the upper limbs, 24 participants were divided into two groups according to their specific job: fine and repetitive tasks and general tasks. Both groups reproduced tasks related to aiming movements, handling and strength of the upper limbs. There were no significant differences between groups in the dexterity and performance of aiming movements. However, the general tasks group had higher grip strength than the repetitive tasks group, demonstrating differences according to job specificity. The results suggest that a particular motor skill in a specific job cannot improve performance in other tasks with the same motor requirements. The transfer of the fine and gross motor skills from previous experience in a job-specific task is the basis for allocating training and guidance to workers. 相似文献

In this experimental study, we compared the embryonic respiration rate in air and water of six East African sesarmid species with intertidal, supratidal and arboreal habits, to highlight possible adaptations in embryonic metabolism to their different lifestyles. The embryos of all analysed crabs showed bimodal respiration, but we did not find a trend towards an enhanced embryonic oxygen uptake in air from the intertidal to the arboreal and supratidal species. However, the late-stage embryos of the most land-adapted species, Chiromantes spp., showed an enhanced metabolism when immersed in sea water that we interpreted as an adaptive recovery mechanism to cope with the storage of by-products due to marine-based metabolic pathways during long emersion periods. Thus, we showed that the embryos of land-adapted species, although still strongly water dependent, are well adapted to semi-terrestrial habitats and represent a minor limiting factor for females, which are not restricted in their emersion period by the oxygen requirements of their embryos. 相似文献
