Evaluation of Potential for Nature-Based Recreation in the Qinghai-Tibet Plateau: A Spatial-Temporal Perspective

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(9), P. 5753 - 5753

Published: May 9, 2022

Nature-based recreation (NBR) is an important cultural ecosystem service providing human well-being from natural environments. As the most concentrated and high-quality wilderness in China, Qinghai-Tibet Plateau (QTP) has unique advantages for NBR. In this study, we designed integrated nature-based potential index (INRPI) based on four aspects: resources, landscape attractiveness, comfort opportunity, reception ability. A combination of analytic hierarchy process (AHP) entropy evaluation method was adopted to assess NBR QTP 2000 2020. The research shows that: (i) INRPI decreases gradually southeast northwest increases slightly (ii) displays a pronounced difference either side Qilian-Gyirong line. areas with very high potentials mainly distributed line, while low northwest. (iii) construction protected effectively improves potential. Areas at diverse levels within obviously increased (iv) Increasing altitude notable effect INRPI, 3000 m critical dividing line QTP. These findings can contribute decision-makers guiding rational use spatial planning land promoting sustainable recreational development.

Protected Natural Spaces, Agrarian Specialization and the Survival of Rural Territories: The Cases of Sierra Nevada (Spain) and Alta Murgia (Italy)

Land, Journal Year: 2022, Volume and Issue: 11(8), P. 1166 - 1166

Published: July 27, 2022

In Europe today, there is increasing interest in the management of protected spaces, not only an attempt to ensure their conservation but also because enormous potential for promoting rural development. These spaces are generally designed from top down, although, number cases, they being promoted by communities themselves. The situation across with regard areas extraordinarily complex due, among other reasons, variety categories and types at regional level. objective this study was compare two parks: Sierra Nevada National Natural Park Andalusia, Spain, Alta Murgia Apulia, Italy, order identify any similarities and/or differences between them. To end, we performed a dynamic analysis evolution crops, uses, livestock species using specific indicator that can detect local dynamics comparing inside parks those immediate surrounding areas. results pointed, part, resurgence these places. both trend observed towards more extensive farming certain crops profitable highly regarded as quality products. risk traditional agricultural landscapes abandoned lost. Various threats were identified relation capital-intensive forms agriculture, especially involving greenhouse cultivation on Mediterranean coast provinces Granada Almeria.

A Decision-Support Tool to Augment Global Mountain Protection and Conservation, including a Case Study from Western Himalaya

Land, Journal Year: 2023, Volume and Issue: 12(7), P. 1323 - 1323

Published: June 30, 2023

Mountains are remarkable storehouses of global biodiversity that provide a broad range ecosystem services underpinning billions livelihoods. The world’s network protected areas includes many iconic mountain landscapes. However, only ca. 19% globally (excluding Antarctica); inadequately (<30% their total terrestrial area) or completely unprotected. To support the UN Convention on Biological Diversity’s Global Biodiversity Framework goal protecting at least 30% lands by 2030, we have developed strategic decision-support tool for identifying and prioritizing which candidate most urgently require protection. test its efficacy, applied to Western Himalaya Case Study Area (WHCSA). six-step algorithm harnesses multiple datasets including Key Areas (KBAs), World Terrestrial Ecosystems, Hotspots, Red List species ecosystems. It also makes use other key attributes opportunities disaster risk reduction, climate change adaptation, developing tourism, maintaining elevational gradients natural ecological corridors, conserving flagship species. This method resulted in nine categories potential action—four follow-up action (ranked order importance priority), five requiring no further immediate (either because countries equipped respond protection deficits KBAs deemed adequately protected). An area-based analysis WHCSA identified 33 regarded as protected, included 29 Mountain Ecosystems. All Category A1: first-priority (located Hotspot countries), urgent attention conservation. Priorities can be fine-filtered regional teams with sufficient local knowledge country-specific values finalize lists priority rapid assessment ensures repeatable, unbiased, scientifically credible allocating resources priorities safeguard biodiverse facing myriad threats Anthropocene.
