The Great Wall of China is more than a wall: it is an extensive cultural route. Pass cities, which are usually large defensive fortresses overseeing an entire fortified area, are an essential part of this heritage and are at the core of the Great Wall’s defense system. Juyong Pass was the closest Pass city to Beijing during the Ming Dynasty when the Great Wall reached its peak. It consisted of five regions—south, east, north, west, and central—that form three fortification levels: core castle, Bao city, and End facility. Based on the Juyong defense area military settlements database, this paper applied spatial analysis methods and found that more than half of the military’s resources for the whole defense area were focused on the western part of the wall, which formed another military core alongside Juyong Pass city. However, the current conservation strategy only focuses on Juyong Pass itself, neglecting the settlements in the western part, thereby destroying the integrity of the Great Wall’s heritage. By clarifying the distribution of cultural heritage in this area, we hope to encourage the preservation of many fortifications according to their authentic historical sphere of control and provide a reference for the sustainable integration of resources along the significant cultural routes of the Great Wall.

In contrast to the modern urban planning, which can be done in short period in terms of the spatial qualified design, the traditional tribe needs longer period in terms of the villagers’ sense of community. The selection of location, planning, and construction reveals the wisdom of the former people’s use of the resourceful life experience. First, the paper employs PHOENICS to simulate the wind environments of two most representative patterns of rural settlements in the southern area of Southern Fujian, China. This was made to compare the different conditions caused by settlements of various architectural groups. Second, the engineering and construction aspects of settlements—such as the width of roads and building structures—will be further analyzed and examined as case study in attempt to discover the favorable environmental factors for generating winds as well as the construction dimension of the settlement, such as the road width and the architectural design. Finally, the paper tends to conclude with an energy conservation strategy applied to the construction of modern communities which has low density and small group buildings.

Commercial traffic in plants and animals has led to severe declines for some species, while others have experienced few if any negative impacts. Given the uncertainty regarding which species are likely to be adversely affected by monetized trade, it would be useful to have a model that could predict wildlife population trajectories of wild-gathered species subsequent to commercialization. We suggest that the indigenous conservation strategy of "taboo" offers important insights into identifying species that are susceptible to over-exploitation through commercial traffic. We describe an economic conservation/extinction model based on the dual concepts of taboo and optimal foraging strategy and examine the model through a detailed case study of vulnerability to perturbation in the case of commercial traffic in Pacific island flying foxes. We suggest that tile virtual eradication of flying foxes from the island of Guam during the Twentieth Century resulted from a cultural predilection among the indigenous Chamorro people for consuming flying foxes coupled with the cultural loss of the traditional taboo conservation system on the island.

The establishment of the forestry educational centre is a good effort made to protect and conserve the forest as well as assisting the public in understanding the landscape changes and sensitivity towards its sustainability. However, there are lacks of consciousness and obligation of the important of landscape conservation in the context of development planning that causes the problem of effective implementation of a conservation strategy exists. Therefore, this paper aims to discuss forest landscapes conservation, particularly in Malaysia with the objectives of to analyse the current landscape features of selected forestry educational centres and to increase awareness among the stakeholders on the importance of conserving and preserving forest landscape towards its sustainability. The study was conducted using two methods specifically via a case study where the Sultan Idris Shah Forestry Education Center (SISFEC) was selected and field observations were conducted to analyse the existing physical condition of the study site. Findings have indicated that SISFEC has successfully conserved the existing landscapes and delivered awareness and knowledge on forest conservation and preservation to the public through several activities such as forestry camps, nature walks, and environmental education programmes. On the other hand, the findings also suggested that the forestry management should give higher priority in maintaining the manmade landscape image of the forest and plan their activities well through good monitoring and efficient management planning which will ensure the site's sustainability in future.

Terrestrial ecosystems in Iceland have undergone tremendous alterations and degradation ever since the Norse first settled there in 870 C.E. Soon after recognizing the value of their land, the Norse tried to restore the damage they had done. Initial environmental protection efforts like these eventually gave way to a deep-rooted Icelandic environmentalism in the early 1900s that was both resolute and idealistic. A widespread ecological movement in the 1970s then later brought forth an ideological shift: calls for Icelandic environmental policy to be more heavily rooted in the sciences. Nevertheless, there are a number of nonscientific factors still contributing to the development of current land conservation policies and practices in Iceland. This article analyzes two case studies: The first considers the development of the 2004–2008 Nature Conservation Strategy of Iceland, while the second examines reforestation policy regarding nonnative Alaskan Nootka Lupin. Both cases speak to these nonscientific factors and how they are intrinsically embedded in environmental policy development in Iceland. These factors include the issues of conceptual clarity (or lack thereof), aesthetic values, conflicting interests, and personal values. Anthropogenically induced environmental impacts have been continually and increasingly felt all across the globe. This case study is therefore not only timely, but it also exemplifies how environmental policy may be developed in responses to these impacts.

In this study, the concept of ecotourism serves as the framework for the investigation of black-faced spoonbill tourism and conservation strategies implemented in Shifen, a community in the Chi-Gu District of Tainan City. It featured an examination of the formulation, planning, and implementation of the conservation strategies and conducted in-depth interviews on individuals from the public sector, local residents, tourists, and nongovernment organizations. Research results identified numerous problems: latent concerns regarding black-faced spoonbills as a tourism resource, poor awareness of ecotourism, difficulties in implementing black-faced spoonbill tourism and conservation strategies, and difficulty maintaining a balance between conservation and residents’ livelihoods. The government is advised to integrate the opinions and suggestions of local residents, promote community participation, and increase job opportunities for local residents to create a win-win model for the development of community-based ecotourism.
