    Spatial effects in the socioeconomic valuation of peri-urban ecosystems restoration
    (Elsevier, 2021-03-30) Martínez Paz, José Miguel; Albaladejo García, José Antonio; Barreiro-Hurle, Jesús; Martínez-Carrasco Pleite, Federico; Perni, Ángel; Economía Aplicada
    In many cities, urban pressure is deteriorating peri-urban ecosystems, despite their high capacity to provide ecosystem services. Against this pressure, restoration projects are being developed to improve the environmental conditions of peri-urban ecosystems. The aim of this work is to determine the economic value and degree of acceptability of a restoration project, the Murcia-Río project, analysing spatial effects. This dimension is incorporated when estimating the willingness to pay (WTP) for the project and when dealing with protest behaviour (PB). A survey was carried out to 401 households in Murcia city (SE-Spain) using the contingent valuation method to obtain a monetary value for the project. We identify that distance to both the project area and substitute areas explain WTP and PB. Based on these findings, we recommend that, to maximize the benefits of such actions, interventions should be targeted to areas with high accessibility and low number of substitutes.

    Otodectes cynotis in urban and peri-urban semi-arid areas: a widespread parasite in the cat population
    (Springer, 2020-03-27) Fanelli, Angela; Doménech Asensi, Guillermo; Alonso de Vega, Francisco-Domingo; Martínez-Carrasco Pleite, Federico; Tizzani, Paolo; Martínez-Carrasco Pleite, Carlos; Sanidad Animal; Facultad de Veterinaria
    The ear mite Otodectes cynotis is a parasite of cats and dogs of considerable veterinary importance, being the most common etiological agent of otitis externa in pets. This study investigates the presence of this parasite in 296 cats from Murcia municipality (SE Spain), and describes possible factors associated with the infestation. Cats were grouped by sex, age, lifestyle, season and provenience. Scraping samples were examined by a microscope to identify the mite. Chi square test was computed and odds ratio was used to measure the association of risk factors with parasite prevalence. Additionally, the spatial distribution of prevalences was investigated and represented through GIS software. Around 30% of the cats (CI95 25–35%) were found positives to O. cynotis. The mite infestation was significantly higher in adult cats, during the winter and in individuals from peri-urban areas. The ectoparasite was found to be widely distributed in the catpopulation of the study area, with an increased risk of infestation in specific peri-urban areas. The results highlight that O. cynotis is a common parasite in areas with Mediterranean semi-arid climate. Given the importance of otodectic mange, and considering that O. cynotis is not a parasite specific to cats, but may also affect dogs and wild carnivores, the information provided by this study is of great value to both pet owners and veterinarian practitioners, and it might help to implement appropriate preventive and control strategies, mainly in free-roaming cats.

    Understanding socio-spatial perceptions and Badlands ecosystem services valuation. Is there any welfare in soil erosion?
    (Elsevier, 2023-03-06) Albaladejo García, José Antonio; Alcon, Francisco; Martínez-Carrasco Pleite, Federico; Martínez Paz, José Miguel; Economía Aplicada
    Badlands are one of the dryland ecosystems where the absence of the regulating ecosystem service (ES) of erosion control enables the provision of cultural ESs, which include, among others, a singular landscape. The lack of consideration of the social value of these areas, due to their low productive value and low biodiversity, has led to their transformation and disappearance. At the same time, the scientific literature that deals with social preferences for the management of these ecosystems is scarce, despite the need to manage these spaces to face the future adverse effects of climate change. This gap can be reduced by establishing a framework for the socio-economic valuation of the Badlands. Therefore, these paper aims to evaluate the social demand for the implementation of management measures to ensure Badlands protection, using as a case study the Region of Murcia Badlands (SE Spain). To this end, a survey was carried out among a representative sample of households in this region; the willingness to pay (WTP) to protect such singular ecosystems and the factors that influence their valuation were studied, especially the spatial component, analysing in detail the protest behaviour (PB). The results show a strong PB in the population (44.29 % of the sample), with a mean WTP of 15.93 €/household/year. Despite the population's preference for the promotion of regulating ESs in eroded areas in general, cultural ESs are more important in the case of Badlands, positively in terms of WTP and negatively for PB. Spatial factors were found to be of great importance in the valuation, showing the existence of local patterns. These results will help decision-makers to achieve more efficient and socially accepted spatial planning in the management of singular eroded areas.
