The study on Watershed Sustainability Index (WSI) has been conducted to analyst the environmental condition in the area incorporating ecological baseline and socio-economic conditions. WSI is an integrated indicator based on basin Hydrology, Environment, Life and Policy (HELP) state condition. It is suitable to be applied in the Langat River Basin in Malaysia which has similar catchment area (up to 2,350 km2) and is one of the UNESCO HELP River Basin since 2004. The WSI analysis which uses a pressure–state–response function based on basin HELP Indicator was done for Langat River Basin by using relevant available 5 years data for the period of 2009 to 2013. It is found that Langat River Basin is having WSI value of 0.68 which falls under the category of medium sustainability (between 0.5-0.8). Based on the maximum value (i.e. 1) or high sustainability (i.e. WSI value more than 0.8) it can be said that Langat is in the good side in term of sustainability. Few management aspects need to be improved and maintained well to be more sustainable. The assessment provides Langat River Basin with more information that is crucial in managing the basin through the adoption of UNESCO’s HELP Framework.

Many natural, environmental, ecological and social economical indexes are involved for urban water ecological security assessment. The index system is built with the pressure-state-response model put forward by Organization for Economic Co-operation and Development. The comprehensive index weights are determined with improved analytic hierarchy process and entropy value method. The model based on fuzzy optimum selection theory is used. The application of this model in Jinan is given as an example. The results correspond basically with the reality.

Los ecosistemas montañosos de Cuba son espacios de biodiversidad, que requieren conservación y acciones que los hagan resilientes y sostenibles en el tiempo. Este trabajo contribuye al desarrollo local de la provincia de Cienfuegos. Es objetivo de esta investigación, facilitar la gestión y evaluación de los indicadores del desarrollo sostenible en el ecosistema Montañas de Guamuhaya mediante la elaboración del Sistema Informático para el Control Ambiental de la Montaña (SICAM). Su principal usuario es la Delegación territorial del CITMA en Cienfuegos, pero puede ser adecuado a los restantes ecosistemas montañosos de Cuba.  Los principales resultados están relacionados con el levantamiento de información posterior al año 1995 por áreas temáticas y por dimensiones del desarrollo sostenible, así como la evaluación del ecosistema, mediante un Índice de desarrollo sostenible aplicando la metodología Presión Estado Respuesta. Palabras clave: gestión, indicadores, índice, áreas temáticas, dimensiones. ABSTRACT   The mountain ecosystems of Cuba are spaces of biodiversity that require conservation and actions that make them resilient and sustainable in the time. This work contributes to the local development of the province of Cienfuegos. The objective of this research, to facilitate the management and evaluation of sustainable development indicators in the ecosystem Mountains of Guamuhaya, through the development of the Computer System for the Environmental Monitoring of the Mountain (SICAM). Its main user is the territorial Delegation of CITMA in Cienfuegos, but it may be appropriate to the remaining ecosystems in mountainous areas of Cuba. The main results are related with the uprising of information after the year 1995 by subject areas and by dimensions of sustainable development, as well as the assessment of the ecosystem, using an Index of sustainable development by applying the methodology Pressure State Response. Keywords: management, indicators, index, thematic areas, dimensions.

Using Landsat remote-sensing data combined with geological information extracted from ALOS and Sentinel-1A radar data, the ecological environment was evaluated in the years 2007, 2008, 2013, and 2017 through gray correlation analysis on the basis of the construction of the pressure-state-response model. The main objective of this research was to assess the ecological environment changes in Wenchuan County before and after the earthquake, and to provide reference for future social development and policy implementation. The grading map of the ecological environment was obtained for every year, and the ecological restoration status of Wenchuan County after the earthquake was evaluated. The results showed that the maximum area cover at a “safe” ecological level was over 46.4% in 2007. After the 2008 earthquake, the proportion of “unsafe” and “very unsafe” ecological levels was 40.0%, especially around the Lancang River and the western mountain area in Wenchuan County. After five years of restoration, ecological conditions were improved, up to 48.0% in the region. The areas at “critically safe” and above recovered to 85.5% in 2017 within nine years after the deadly Wenchuan earthquake of May 12, 2008. In this paper, we discuss the results of detailed analysis of ecological improvements and correlation with the degrees of pressure, state, and response layers of the Pressure-State-Response (PSR) model.
