    Alternatives to Lime Plaster: Evaluation of Paints with Inorganic Pigments for the Conservation of Heritage Buildings in Peru
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025)
    Lime plaster has historically been a key material in the preservation of architectural heritage in Peru; however, its availability has been restricted by state regulations that limit its production and commercialization. This study evaluates the performance of paints formulated with inorganic pigments extracted from soils in the Cusco valley, combined with natural and synthetic binders, as a sustainable alternative for the protection of heritage buildings in this Andean region characterized by high altitude, wide thermal variations, and high solar radiation. Adhesion, hardness, drying time, and weather resistance tests were conducted according to applicable ASTM standards for architectural coatings. The results show that these formulations exhibit good adhesion to historic surfaces and greater durability against extreme environmental conditions compared to traditional lime plaster. Their potential compatibility with historic substrates and lower environmental impact suggest that these paints represent a viable alternative in sustainable conservation strategies; however, further studies are needed to more accurately characterize the mineralogical composition of the pigments used.

    Understanding Urban Resilience and SDGs: A New Approach in Decision-Making for Sustainable Cities
    (John Wiley and Sons, 2025)
    Recent crises exacerbate social, environmental, and economic problems affecting the Sustainable Development Goals (SDGs) and urban resilience. Urgent action is needed to address these issues. The paper aims to (i) broaden the debate on urban resilience and the SDGs and (ii) examine how the interconnection of Urban Spatial Resilience (USR) and the SDGs can contribute to sustainable cities and communities. The research is developed through a literature review and a bibliometric analysis, followed by a quantitative approach using modeling and simulation. The results reveal three critical elements that can impact urban resilience and sustainable development: SDG11, urban spatial structure resilience, and urban spatial form resilience. Other findings indicate that SDG13 and SDG6 have a significant indirect relationship with urban resilience. The study provides policy implications supporting urban resilience and the SDGs.
