Abstract

Sustainable agricultural development in natural heritage sites poses a challenge, requiring food security without compromising the conservation of ecosystems and their outstanding universal values (OUV). The Galapagos Islands, recognized as a Natural World Heritage, have problems of scarce water and arable land, compounded by anthropogenic pressures such as high population and tourism growth and dependence on food imports. The objective of this research is to evaluate the environmental impacts of implementing agricultural greenhouses in the Galapagos by applying a traditional environmental matrix alongside a UNESCO World Heritage approach, integrated with a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis, to formulate strategies for strengthening local agriculture without compromising ecosystems. This study employed a semi-quantitative methodological approach, integrating three key aspects: (i) a baseline of agricultural information and water availability on the islands; (ii) an integrated Environmental Impact Assessment (EIA) approach to greenhouse implementation; and (iii) sustainable agricultural development and environmental impact mitigation strategies. The results of the traditional EIA and the UNESCO approach through the OUV showed negative impacts classified as insignificant to moderately significant. For the evaluated design, these impacts can be managed through the active participation of academia, the community, and government entities. However, their scalability depends on a more in-depth analysis of the potential long-term risks associated with the availability of natural resources, microplastic pollution, and the use of agrochemicals. Among the proposed strategies, the importance of monitoring water and soil quality and of agricultural and environmental education campaigns in the community was highlighted. This study presents agricultural greenhouses as well-known alternatives for food self-sufficiency, adapted to the realities of the island territory and the objectives of ecosystem conservation. The proposed methodological approach can be applied in protected areas to promote conservation and sustainable agricultural production.
