-The case study examines the economic aspects of cultural heritage conservation and deals the valuation of economic value in monetary terms, using the application of the contingent valuation method to the castle of Nicastro (Catanzaro, Italy). For the construction of the hypothetical market and the selection criteria and approach to subjects of the statistic sample, the proposed solutions work with operative adjustments, dictated by the characteristics of the resource in question and in general for all cultural resources. The study has produced reliable answers to questions of willingness to pay, expressing the measure of the different components of the value (use value and existence value) contribute to the composition of the total economic value. The study allowed to verify the possibility of using the contingent valuation as a political tool. The particular question format, which combines ‘double bounded dichotomous choice' and ‘open ended' techniques has allowed us to take a sensitivity analysis, defining the measure of willingness to pay.Key words: evaluation cultural resource, contingent valuation method, willingness to payParole chiave: valutazione, beni culturali, metodo di valutazione contingente, disponibilitŕ a pagare

ABSTRACT This research aimed to estimate the seasonal economic value of ecosystem goods and services from research on the use of mangroves in the Cuiarana community in the Eastern Amazon. The methodology of Total Economic Value was used, through interviews with 15 residents who extract products from the mangrove. For the ecosystem services, atmospheric carbon (measured by a micrometeorological tower), and organic carbon (monitored by soil sampling during 2017) were used. In determining product values, the quantities extracted at market prices and the value of services were estimated using carbon credits. The results indicate that the ecosystem produces 9 community assets, that generate R$ 75,033.50 (US$ 23,622.93 ha/year) and R$ 17,627.15 (US$ 5,549.58 ha/year) for capture and storage respectively. The VET value corresponded to R$ 986,132.50 (US$ 310,465.79). Ecosystem services and the economic values of atmospheric (p = 0.0278) and soil carbon credit (p = 0.0354) indicated higher importance in the rainy season due to the precipitation that favored an increase in the amount of carbon. This behavior was verified by the Principal Components Analysis (50.1%), which showed that in the less rainy season goods are more important when compared to the ecosystem services.

The Future

Crop potential yields in cropland are the essential reflection of the utilization of cropland resources. The changes of the quantity, quality, and spatial distribution of cropland will directly affect the crop potential yields, so it is very crucial to simulate future cropland distribution and predict crop potential yields to ensure the future food security. In the present study, the Cellular Automata (CA)-Markov model was employed to simulate land-use changes in Northeast China during 2015–2050. Then, the Global Agro-ecological Zones (GAEZ) model was used to predict maize potential yields in Northeast China in 2050, and the spatio-temporal changes of maize potential yields during 2015–2050 were explored. The results were the following. (1) The woodland and grassland decreased by 5.13 million ha and 1.74 million ha respectively in Northeast China from 2015 to 2050, which were mainly converted into unused land. Most of the dryland was converted to paddy field and built-up land. (2) In 2050, the total maize potential production and average potential yield in Northeast China were 218.09 million tonnes and 6880.59 kg/ha. Thirteen prefecture-level cities had maize potential production of more than 7 million tonnes, and 11 cities had maize potential yields of more than 8000 kg/ha. (3) During 2015–2050, the total maize potential production and average yield decreased by around 23 million tonnes and 700 kg/ha in Northeast China, respectively. (4) The maize potential production increased in 15 cities located in the plain areas over the 35 years. The potential yields increased in only nine cities, which were mainly located in the Sanjiang Plain and the southeastern regions. The results highlight the importance of coping with the future land-use changes actively, maintaining the balance of farmland occupation and compensation, improving the cropland quality, and ensuring food security in Northeast China.
