From preference to landscape sustainability:a bibliometric review of landscape preference research from 1968 to 2019

Landscape preference(LP)studies highlight one of the most important issues of human-environment relationship,and their related publications have increased rapidly over the last two decades.However,there is no systematic review with a holistic understanding of this field.here we applied a bibliometric approach to examine the evolution of LP research and identify its status and future prospects.We obtained 7,637 LP research publications from Web of Science core collection from 1968 to 2019 and analyzed the characteristics of publication outputs as well as performances in various countries and institutions.Besides,content keywords analysis was conducted to discover the drivers,focus,motivation,and trends of LP research.We found that 1)publications,subject categories,and active journals increased rapidly since the 2000s;2)the USA,England,and Australia are the leading countries in LP research,while China is starting to have some influence;3)LP research is most closely linked to ecological and environmental studies,being developed by objective drivers,i.e.,interactions with landscape change,and subjective motivations;and 4)LP research is advancing the landscape sustainability science,integrating natural and social science together through ecosystem services.By comprehensively reviewing the evolution and prospect of LP research,we provide insights for further research in this field.

THE CAYUGA MEDICAL CENTER A Case Study in Landscape Master Planning and Sustainability

INTRODUCTION Long-term planning is essential for larger institutions to achieve sustainable goals and visions.To be truly sustainable,individual projects must fit within a larger scope of campus planning.Landscape and site systems such as parking,transportation,pedestrian connectivity,storm water treatment,and human health and well-being must be considered and coordinated.

MASTER PLAN TO ROBUST PRACTICE: THE EVOLUTION OF SUSTAINABLE LANDSCAPE PRACTICES AT GEORGIA INSTITUTE OF TECHNOLOGY

Universities across the globe are recognizing the need to implement sustainable landscaping practices in order to support wildlife, improve water quality and positively impact human health and wellbeing. Georgia Institute of Technology learned that such sustainable practices, when properly aligned with overarching campus goals, can also enable continuous, collaborative decision-making and student engagement. The Georgia Institute of Technology (Georgia Tech) is a leading research university situated on 426 acres of land in midtown Atlanta, Georgia, with a student population of 27,000 (Fall 2017). An urban oasis in the center of town, Georgia Tech’s campus offers 312.5 landscaped acres, 3.5 naturalized acres and 110 acres of buildings. The campus is also a level II certified arboretum boasting 12,000+ trees in its urban forest. Prior to the 1990s, Georgia Tech was commonly referred to as a concrete and brick campus with very little landscape. However, in 1999 all that changed when the Georgia Tech administration decided to invest in sustainable landscaping, including the recruitment of qualified staff with specific skill sets to take on this challenge. The Institute’s initial landscape master plan objectives were to reduce impervious surfaces such as surface parking lots, increase woodland coverage and enlarge the tree canopy. A significant amount of sustainable landscape practices and collaborative methods grew from these initial objectives. Establishing a plan with clear goals, having the support of executive leadership and employing the right team members enabled the Georgia Tech campus to be transformed from a concrete jungle to a forested, urban oasis in less than 20 years.

Quantifying urbanization levels on the Tibetan Plateau with high-resolution nighttime light data

The Tibetan Plateau(TP)is undergoing rapid urbanization.To improve urban sustainability and construct eco-logical security barriers,it is essential to quantify the spatial patterns of urbanization level on the TP,but the existing studies on the topic have been limited by the lack of socioeconomic data.This study aims to quantify the urbanization level on the TP in 2018 with Luojia1-01(LJ1-01)high-resolution nighttime light(NTL)data.Specifically,the compounded night light index is used to quantify spatial patterns of urbanization level at mul-tiple scales.The results showed that the TP had a low overall urbanization level with a large internal difference.The urbanization level in the northeast,southeast and south of the TP was relatively high,forming three hotspots centered in Xining City,Lhasa City and Shangri-La City,while the urbanization level in the central and western regions was relatively low.The analysis of influencing factors,based on the random forest model,showed that transportation and topography were the main factors affecting the TP’s spatial patterns of urbanization level.The comparison analysis with socioeconomic statistics and traditional NTL data showed that LJ1-01 NTL data can be used to more effectively quantify the urbanization level since it is more advantageous for reflecting the spatial extent of urban land and describing the spatial structure of socioeconomic activities within urban areas.These advantages are attributed to the high spatial resolution of the data,appropriate imaging time and unaf-fected by saturation phenomena.Thus,the proposed LJ1-01 NTL-based urbanization level measurement method has the potential for wide applications around the world,especially in less-developed regions lacking statistical data.Using this method,we refined the measurement of the TP’s urbanization level in 2018 for multiple scales including the region,basin,prefecture and county levels,which provides basic information for the further urban sustainability research on the TP.

Sustainable Post-Disaster Solutions--London 1666, Lisbon 1755 and Japan 2011reLearning from the Past

Natural disasters have impacted human settlements throughout the centuries, imparting lessons as new ways and strategies to avoid or minimize the damage inflicted by the natural processes. This on-going process has created new landscapes instrumental to man＇s balance of the use of the land by taking into account the probability of further natural disasters. This paper discusses the responses to disaster challenges taking past experiences on ＂after disaster decisions＂ in London 1666, in Lisbon 1755 as a framework to analyse the more recent Great East Japan Earthquake disaster. The concept of sustainability which adds a new perspective to the subject of more resistant solutions and strategies as the opportunity for a new design is presented by the destruction. Sustainable environmental, social and cultural issues improvements are important goals introduced in the 20th century and enrich long-term human adaptations to natural processes. They are also considered in this analysis as an evolving final product of the human adaptation that results in more durable cultural landscapes.

REENGAGING THE LAND AT THE GEORGE W.BUSH PRESIDENTIAL CENTER

In planning the George W.Bush Presidential Center in Dallas,Texas,former First Lady Laura Bush presented a very clear vision of what the Center should epitomize:“Because George was the first president of the new millennium,I wanted it to be forward and modern.”1 For the president and Mrs.Bush this meant making the building and landscape environmentally responsible,beautiful,and welcoming.In particular,their love of native Texas landscapes was an important framework for transforming the project’s urban site into a park that was sustainable and experientially rich for visitors.Sustainability was addressed from the start with smart planning that privileged contiguous parkland over impermeable surfaces and structures.Simultaneous consideration of every landscape component—-stormwater,plants,soil,topography,and more—netted cohesive natural systems that are better able to succeed with short-term establishment and provide enduring long-term health,the ultimate goals for a sustainable landscape.

Challenges and Countermeasures for the Sustainable Development of Nationally Important Agricultural Heritage Systems in China

In 2012 the Ministry of Agriculture of China launched a project exploring Nationaly Important Agricultural Heritage Systems （China-NIAHS）. Through two rounds of applications and selection in 2012 and 2013, 39 traditional agricultural systems were selected and designated as China-NIAHS, including 19 forestry systems, 14 planting systems, four agricultural complex systems and two other systems. From a system origin perspective there were 24 agricultural systems, some dating back 1000 years. Twenty heritage systems are located in areas inhabited by ethnic minorities. Agricultural heritage systems face general challenges, such as ecosystem degradation and destruction, loss and abandonment of traditional agricultural technologies and landscapes, lagging agriculture scale and industrialization, and limited farmer beneift-sharing and incentives. Compared to other types of heritage, the conservation and development of agricultural heritage systems is more complex and dififcult. In order to achieve sustainable development of agricultural heritage systems, the government should play a leading role and improve ifnancial support functions. Local people should also explore market-oriented approaches and adaptive management methods on protection and development of NIAHS. Multi-participation and beneift-sharing mechanisms should be established and basic research needs to be strengthened.

Chinese Built-up Land in Floodplains Moving Closer to Freshwaters

Human proximity to water and its dynamics are important to understanding the socio-hydrological dilemma between using floodplains and avoiding flood risk.However,previous studies have not distinguished between the water proximity of built-up land in floodplains(BLF)and the water proximity of built-up land outside floodplains(BLOF).This article provides a new and spatiotemporal perspective of the BLF water proximities for understanding the changing flood risk in China.The results show that China’s BLFs had an average water proximity of 5.41 km in 2014.Most of the BLFs(62%,25.889103 km2)were located within 3 km of waterbodies.From 1990 to 2014,China’s BLFs increased rapidly by 81%from23.069103 km2 to 41.749103 km2,of which a large portion(57%)was concentrated in water surroundings(≤km),shortening the distance between BLFs and waterbodies by 169 m.The BLF growth concentrated in water surroundings even in areas where BLFs have an overall increasing distance from waterbodies.Both the increases in the BLFs and their proximity to waterbodies can increase flood exposure and exacerbate flood risk.The scientific community and policymakers should pay attention not only to the volume of BLF growth,but also its spatial relationship with waterbodies.
