Asbestos rehabilitation project as a model of landscape sustainability

Greece was one of the biggest producers of asbestos in the world as well as a consumer. It took advantage of the asbestos rich Zidani mine, in the region of Western Macedonia in Greece. However, due to serious health problems caused by inhaling asbestos, it was banned in 1979 and the mine closed in March 2000. Rehabilitation management of the abandoned asbestos mining area, the depositions in the open - pit mining area and the tailings remnants was necessary in order to avoid health and environmental problems in the wider area The detailed soil protection and rehabilitation project of the degraded mining area was implemented taking all necessary and appropriate safety and health measures according to the requirements of the relevant E.U and National legislation, so that accidents would be prevented. Results show that the rehabilitation, soil protection and enhancement of the area help the ecosystems to be sustainable, ecologically and socially acceptable

The Effects of a Megafire on Ecosystem Services and the Pace of Landscape Recovery

(1) Background: Megafires have affected several regions in the world (e.g., Australia, California), including, in 2017, the central and south-central zones of Chile. These areas represent real laboratories to monitor the impacts on the sustainability of landscapes and their recovery after fires. The present research examines the modification of dynamics and the provision of ecosystem services by a megafire in a Mediterranean landscape in central Chile, combining remote sensing technologies and ecosystem service assessments. (2) Methods: Land cover and spectral indices (NBRI, BAIS-2, NDVI, and EVI) were measured using Sentinel-2 imagery, while the provision of ecosystem services was evaluated using an expert-based matrix. (3) Results: The megafire affected forest plantations, formerly the dominant land cover, as well as other ecosystems, e.g., native forests. After five years, the landscape is dominated by exotic shrublands and grasslands. (4) Conclusions: The megafire caused a loss of 50% of the landscape’s capacity to supply ecosystem services. Given that native forests are the best provider of ecosystem services in this landscape, restoration is a key to recovering landscape sustainability.

The Role of Healing Gardens in The Landscape Sustainability For Public Gardens

There were emergences trends towards achieving sustainability in landscape. But the study of the role of healing gardens in the landscape sustainability for the public gardens had not been studied previously in recent literatures. The research hypothesis is that healing gardens have a role in the landscape sustainability for public gardens. The research depends on a descriptive analytical study for public garden samples, which applied the design principles and elements of healing gardens (accessibility, Sense of control, Flexibility, etc). These gardens also relied in their designs on the basic principles of sustainability. The results showed that healing gardens effectively contribute achieving landscape sustainability for public garden through the use of natural materials, the cultivation of local plants, consistent with the local climate, and enhancing social interaction and sensory interaction with the landscape.

The Varying Roles of Ecosystem Services in Poverty Alleviation Among Rural Households in Urbanizing Watersheds

ContextUnderstanding the relationship between ecosystem services and human well-being in rural areas of rapidly urbanizing watersheds is one of the core research questions of landscape sustainability science. It is important for poverty alleviation and forming related policies. However, there is insufficient investigation on the impact of ecosystem services on poverty alleviation at the household level in such regions. ObjectivesThis paper investigates whether household characteristics play an important role in connecting ecosystem services and poverty alleviation in a rapidly urbanizing landscape from the perspective of landscape sustainability science.MethodsWe use an urbanizing watershed with a large number of poor people, analyzing the impacts of ecosystem services on poverty alleviation among different types of rural households based on surveys, cluster analysis, and multinomial logit models. ResultsThe results suggested that neither provisioning services nor cultural services that are received by the households were significantly associated with poverty alleviation (p>0.1). However, the decline in one regulating service (natural disaster prevention) had a significant, negative impact on poverty alleviation (p<0.1), and the probability for natural disaster-affected farmers to fall into poverty was approximately 32 times higher than that for those who were not. ConclusionsDifferences in household-level endowments largely explained the diverging roles of ecosystem services on poverty alleviation. Therefore, in urbanizing watersheds, pro-poor policies such as providing agricultural insurance and targeted support (e.g., interest-free microcredit) should be adopted to improve the ability of poverty-stricken households to cope with disasters and prevent them from returning to poverty.
