Relationship between landscape pattern and human disturbance from 1990 to 2018 ...
Quinta-Nova, L.C.The land use/land cover pattern of landscapes as the main element of the landscape structure has an important role in landscape management, nature conservation, and preservation, considering its ability to provide valuable information about the spatial distribution and changes in land cover that occur on the Earth's surface. On the other hand, human activities have caused significant impacts on ecosystems, resu...
GIS based approach to analyse the relationship between land units and land use ...
Quinta-Nova, L.C.Land units refer to coherent spatial areas characterized by a degree of homogeneity concerning certain properties like geology, soils, and climate. The Land use mosaic corresponds to a circumstantial layer representing the landscape’s present state, depicting the present resource allocation factors. Nevertheless, the stable potential layer is related to the stable characteristics of each site and allows the ide...
Predicting the effectiveness of Tagus International Nature Park in protecting v...
Quinta-Nova, L.C.; Ribeiro, SílviaClimate change induces a redistribution of life on Earth, affecting protected areas' effectiveness. Species shift their ranges under climate change to track suitable climate, mainly shifting poleward and toward higher elevation. They often face degraded habitats in human-dominated landscapes and a higher extinction threat. Also, climate change may result in the loss of combinations of climatic conditions restri...
GIS-based analytic hierarchy process model for a forest residuals biorefinery s...
Pedro, Nuno; Quinta-Nova, L.C.In general terms, renewable energy sources are characterized by their decentralized availability, ability to quickly self-regenerate, and the reduced environmental impacts resulting from their use. The conversion of forest biomass into energy will make it possible to transform waste into raw material for the energy industry while promoting forest management. Reducing the forest's fuel load will be responsible f...
A spatial decision support system to assess the nature-based tourism developmen...
Quinta-Nova, L.C.With its potential to conserve environmental values, integrate local communities, boost sustainable development, generate jobs, improve infrastruc-ture, and support the local economy, nature-based tourism is a significant source of income for local communities, stimulating entrepreneurship and economic di-versification. Based on this principle, this study aims to assess the potential of existing natural resourc...
Recent land use land cover change tendencies in Continental Portugal: Are they ...
Quinta-Nova, L.C.The Land Use Land Cover (LULC) pattern of landscapes is a key element of basic landscape structure; accordingly, this pattern has a vital role in landscape management, nature conservation, and preservation. On the other hand, the human impact on the ecological environment has attracted significant attention. The study aimed to investigate the relationship between human disturbance intensity and landscape patter...
Land evaluation of suitability for the practice of foot orienteering using a sp...
Quinta-Nova, L.C.Orienteering is a sport in which the orienteer completes a course of control points in the shortest possible time, aided only by a map and compass, involving the choice of itineraries, through reading and interpreting the map and its relationship with the terrain. The most important factors for selecting areas for orienteering are difficult and challenging terrain that enables good course setting. Finding a sui...
Suitability analysis of alternative agroforestry systems in Beira Baixa (Portug...
Quinta-Nova, L.C.The proliferation of single-species tree plantations, predominantly consisting of pine or eucalyptus trees, poses a significant challenge in Portugal. These monoculture plantations, driven by the pulp and paper industry, have expanded extensively across the country. Unlike mixed forests or agroforestry systems, monoculture plantations are more prone to fire spread and lack the benefits of water retention and er...
Trend forecasting in swimming world records and in the age of world record holders
Costa, Mário; Quinta-Nova, L.C.; Ferreira, Sandra; Costa, Aldo M.; Santos, Catarina CostaThis study aimed to forecast trends in swimming world records (WRs) and in the age of record holders. A total of 566 individual freestyle WRs (290 for males and 276 for females) were retrieved from open access websites. The frequency of observations in WRs in each decade and event was computed for males and females. The swimmers’ chronological age was converted into decimal age at the time of breaking the world...
Relationship between landscape pattern and human disturbance in Serbia from 200...
Quinta-Nova, L.C.; Naranjo Gómez, José Manuel; Vulevic, Ana; Castanho, Rui Alexandre; Loures, LuísThis study intends to verify how the alteration of the landscape configuration, represented by different metrics of configuration and diversity, is related to the intensity of human disturbance. The objectives of the study are: (1) to quantify the change in land use/land cover (LULC) patterns and the degree of human disturbance in Serbia between 2000 and 2018, and (2) to study the relationship between LULC conf...
