“…Subsequent studies have modified the INRA index to include more categories. In [89], 27 additional subcategories are added, providing a greater degree of detail in the definition of the INRA index. The relative value of anthropization assigned to each of these new categories is obtained as a result of applying multiple-criteria decision analysis, obtained by expert judgement.…”

For the first time, this paper introduces and describes a new Weighted Environmental Index (WEI) based on object-oriented models and GIS data. The index has been designed to integrate all the available information from extensive and detailed GIS databases. After the conceptual definition of the index has been justified, two applications for the regional and local scales of the WEI are shown. The applications analyze the evolution over time of the environmental value from land-use change for two different case studies in Spain: the Valencian Region and the L’Alcora municipality. Data have been obtained from the Spanish Land Occupation Information System (SIOSE) public database and integrate GIS information about land use/land cover on an extensive, high-detailed scale. Results demonstrate the application of the WEI to real case studies and the importance of integrating statistical analysis of WEI evolution over time to arrive at a better understanding of the socio-economic and environmental processes that induce land-use change.

“…These changes endanger the survival of mangroves in the Sanquianga Mangrove National Reserve(Restrepo and Cantera, 2013).Like Mexico, between 1970 and 2005, the main anthropogenic activities with an impact on mangrove areas in the Central and South Pacific were the establishment of aquaculture farms and tourist areas(Velázquez- Salazar et al, 2021). For the period from 2005 to 2010, the notable developments were hydraulic infrastructure and construction zones(Velázquez-Salazar, et al, 2019). In the Central Pacific (extreme north of the province), the growth of tourist cities such as Puerto Vallarta, Barra de Navidad and Manzanillo stands out, while further south, the development and port expansions of Lázaro Cárdenas in Michoacán and Acapulco in Guerrero have also contributed to the loss of mangrove cover.…”

Mangroves of the Tropical East Pacific (TEP) province is a regional ecosystem subgroup (Level 4 unit of the IUCN Global Ecosystem Typology), present in the coastal ecoregions of the Mexican Tropical Pacific, Chiapas-Nicaragua, Nicoya, Panama Bight, and Guayaquil. In 2020, mangroves cover 7782 km2 in the province, representing 5.3% of the global coverage. In the province, there are eight true mangrove species; however, regional experts recognize other related plants classified as associated plants. The IUCN Red List includes 224 species (217 Animalia and seven Plantae species), supported by records in the Global Biodiversity Information Facility GBIF. It is estimated that the mangroves of the TEP showed a net change of -1.9% from 1996 to 2020; under this trend, a decrease of 3.3% is projected in 50 years, which is below 30%, classifying criterion A2 as least concern. However, based on indicative figures, a decrease of around 40% was estimated in the last 50 years (1970-2020); which as this exceeds 30%, the mangroves are vulnerable under Criterion A1. Although threats such as deforestation, human activities, pollution, infrastructure development, modification of natural systems, and invasion of exotic species are reported, none promote total disappearance; therefore, criteria B3 is classified as least concern. In a sea-level rise scenario (IPCC RCP8.5), ≈ 9.8% of the TEP mangroves would be submerged by 2060, which is below the 30% risk threshold for criterion C2. Furthermore, 1.5% of the province's mangrove is suffering degradation, with the potential to increase to 4.5% over 50-year period; this ranks the mangroves as least concern under criterion D2b. Overall, the Tropical East Pacific mangrove ecosystem was assessed as Vulnerable (VU) with the available information. It is considered that there is insufficient data to assess the other criteria, therefore, it is recommended to update the data to increase the precision of the evaluation and enable the quantitative analysis of risks.
