    Economic valuation of allotment gardens in peri-urban degraded agroecosystems: the role of citizens’ preferences in spatial planning
    (Elsevier, 2021-02-15) Albaladejo García, José Antonio; Alcon, Francisco; Martínez Paz, José Miguel; Economía Aplicada; Facultad de Economía y Empresa
    Allotment gardens (AGs), one of the basic types of urban gardening, provide goods and services to the urban population beyond food supply. Therefore, the efficient planning and management of AGs must take into account both the social welfare provided by the ecosystem services (ES) associated with these spaces and spatial considerations. The distance of the AGs from the citizens, their accessibility and the presence of substitutes are aspects that have not been studied extensively in the scientific literature. In this context, this paper evaluates the creation of AGs in a peri-urban degraded agroecosystem in Murcia (SE-Spain). To this end, the values of ES are quantified economically, as are the influences of the socio-economic and spatial characteristics. A survey was undertaken on a representative sample of households in Murcia city, from which the willingness to pay (WTP) for owning an AG and the factors influencing the valuation were determined. The results indicate that provisioning services are the ES valued most highly, followed by regulating and cultural ES. The valuation of the project for the whole population is 5.4 €/household/month, with a WTP of 17.2 €/household/month for owning an AG plot. Multivariate analysis showed the importance of ES and spatial factors in this valuation. This WTP spatial study shows the existence of local patterns to be considered in the evaluation of new AGs location alternatives. These results will be useful to urban planners in their decision making.

    (2018-03-01) El Amraoui, Sidi Mohamed; Rouchdi, Mohamed; Mourad, Bouziani; Abdelwahed, El Idrissi
    Mejorar el conocimiento del proceso de programación de los recursos de tierra por el uso de la urbanización es el objeto de este trabajo. Esto a través de la presentación de un modelo basado sobre la utilización combinada del análisis jerárquico multicriterio (AHP) en un lado, y de otro lado de las sistemas de información geográfica (GIS). La metodología elegida ha mostrado su pertenencia en la resolución de los problemas espaciales complejos. La determinación de los criterios relacionados con el objetivo y la distribución de los atributos y los datos geográficos a nivel de la provincia de Khémisset ha permitido, en primer lugar, a priorizar los indicadores, en segundo lugar, a evaluar el fenómeno, y tercero, a comparar diferentes escenarios de gestión del área del estudio. Esta cuantificación es el resultado de la intersección de los datos y la agregación multicriterio según el método AHP y el enfoque de la suma ponderada (WSM) modelando de manera participativa los factores dependientemente de sus pesos. El proceso adoptado ha ofrecido también la posibilidad de presentar en forma de Atlas la ocupación del sol destinado a la urbanización y ayudar a los especialistas a elegir la vocación urbanística de los espacios, abrirlos para la urbanización, preservarlos o conservarlos.

    (Consejo Superior de Investigaciones Científicas, 2024-06-04) Martínez García, Victor; Zabala García, José Ángel; Albaladejo García, José Antonio; Lopez Becerra, Erasmo; Sánchez Navarro, Virginia; Sánchez Navarro, Jorge Luís; Boix Fayos, Carolina; Martinez Paz, Jose Miguel; Alcon, Francisco; Economía Aplicada
    Aim of study: This study proposes a crop diversification innovative business model based on stakeholder preferences towards different incentive alternatives. Area of study: South-East Spain. Material and methods: Citrus intercropping practices in South-East Spain has been used as case study. Stakeholders’ preferences for crop diversification incentives were investigated by using a multicriteria approach, and those results were integrated into the development of a business model canvas. Main results: Including crop diversification practices as environmental practices within the operational programmes of producer organizations is seen the most preferred incentive over which the business model canvas is developed. Research highlights: The establishment of business opportunities for crop diversification practices would facilitate the overcoming of adoption barriers along the agrifood value chain and would promote health and sustainable food systems.
