Core Areas

The purpose of this article is to explore the possibility of creating an ecological network that includes core areas, buffer zones, ecological corridors, and restoration areas in the section of the Shamakhi district of the Shahdagh National Park (Azerbaijan). Materials and methods. As materials, we used vector and raster data, as well as literature materials to determine and analyse the elements of an ecological network. Operations were performed by using ArcGIS 10.8 and ERDAS Imagine software. During the field research, observations were made in order to match the elements of the ecological network with the cameral study. Results. In the article, protected natural areas are presented as the core areas and the surrounding areas as buffer zones under the relevant legislation. Riverbeds, mountain passes, trails, and forests which should be planted in the areas we offer, were considered as main factors during the construction of ecological corridors in the national park and the buffer zones. In this case, “least-cost” modelling was applied and ecological corridors were designated to ensure connectivity between core areas. As a result, the optimal ecological network model for the study area has been developed and mapped in the article. Conclusion. The high growth rate of consumption of natural resources led to the loss of biodiversity in the last decades. At present, it is important to take the necessary measures, and connectivity of ecosystems and natural complexes play an important role in sustainability. The presented model in the study can help to conserve biodiversity, reduce anthropogenic impacts, eliminate environmental barriers, and develop appropriate forms of land use.

The high growth rate of consumption of natural resources by people in the last century have seriously and negatively affected ecosystems and led to the loss of biodiversity. At present, it is important to take the necessary measures to ensure sustainable development and biodiversity conservation. Ecological networks play an important role in maintaining and controlling the stability and balance of communication between ecosystem complexes. For this purpose, the possibility of creating an ecological network that includes core areas, buffer zones, ecological corridors and restoration areas in the section of Shamakhi district of the Shahdagh National Park was explored. The designated buffer zone of the national park includes 14 villages and 1 settlement type administrative unit. Mountainous landscapes predominate in the area, and the absolute height ranges from 500-200 m. Riverbeds, intermountain depression, mountain passes, trails and forests which should be planted in the areas we offer, were considered as main factors during the construction of ecological corridors in the national park and the buffer zones. The materials obtained from the literature and our field studies, also, vector and raster data were used during the site identification. The data was processed in software such as ArcGIS 10, ERDAS Imagine, Global Mapper, Google Earth, etc. Existing ecosystems were identified, and areas were calculated in separate elements of the ecological network in the study area.

Cultivation Techniques

The goal of this research was to identify the dryland cereal crop seed plasma types growing around Kelimutu National Park, located in Ende district on the island of Flores in Indonesia, by observing crop morphology and cultivation techniques.  Cereal crops represent the largest source of carbohydrates in the regional diet in comparison to other food groups in this area where dry land makes up 80% of the total available land.  It is estimated that the Ende district of Flores has adequate potential to produce dryland cereal as a staple food crop.  Previous studies have shown that farmer preference is shifting towards the cultivation of crops with a higher economic value which threatens the existence of some cereal crops.  Concurrently, shifts in eating habits have made rice a staple food in this region, leading to increased consumption and threatening the existence of other cereal crops.  Furthermore, outsiders tend to think of areas like Flores as being impoverished, with frequent problems with food security. Currently, there is a lack of knowledge within the youth population about the types of foods, especially cereals, which are rich in nutrients and their use in rituals.  This research aims to address this gap by collecting information on cereal crops in and around Kelimutu National Park for dissemination through educational and cultural tours. This study was conducted in the eastern subdistrict of Ndona, Flores and Wolojita Detusoko between June and December 2011.  Study findings identified 5 main cereal crops: paddy fields (consisting of: Are Rumba, Are Sela, Are Obo, Are Laka, Amera, Eko Ndale, Kea Ria, Are Mera, Are Kea Mboa, Eko Ena), corn (consisting of Java Roga, Nggela Java, Java, Keo Ri’a), sorghum (consisting of mera Lolo, Lolo Mite and Lolo Telo Leko), barley (consisting of Mera and Wete Wete Bara) and millet (consisting of Ke’o Mite and Ke’o).  Of the five types of cereal crops identified, one type (Pega, a subspecies of barley with a sorghum-like panicle) is not found in four of the districts.  It was found that corn, classified as a native plant, is strengthened through cultivation by re-seeding.  Study results illustrated that corn in this area is of reduced genetic quality, as illustrated by the fact that 3-4 cobs did not develop.  Alternatively, the Ke’o Bara strain of barley has a morphology and panicle strand number (270-300) that suggest that this species is typical of this region.

Habitat destruction and declining ecosystem service levels caused by urban expansion have led to increased ecological risks in cities, and ecological network optimization has become the main way to resolve this contradiction. Here, we used landscape patterns, meteorological and hydrological data as data sources, applied the complex network theory, landscape ecology, and spatial analysis technology, a quantitative analysis of the current state of landscape pattern characteristics in the central district of Harbin was conducted. The minimum cumulative resistance was used to extract the ecological network of the study area. Optimized the ecological network by edge-adding of the complex network theory, compared the optimizing effects of different edge-adding strategies by using robustness analysis, and put forward an effective way to optimize the ecological network of the study area. The results demonstrate that: The ecological patches of Daowai, Xiangfang, Nangang, and other old districts in the study area are small in size, fewer in number, strongly fragmented, with a single external morphology, and high internal porosity. While the ecological patches in the new districts of Songbei, Hulan, and Acheng have a relatively good foundation. And ecological network connectivity in the study area is generally poor, the ecological corridors are relatively sparse and scattered, the connections between various ecological sources of the corridors are not close. Comparing different edge-adding strategies of complex network theory, the low-degree-first strategy has the most outstanding performance in the robustness test. The low-degree-first strategy was used to optimize the ecological network of the study area, 43 ecological corridors are added. After the optimization, the large and the small ecological corridors are evenly distributed to form a complete network, the optimized ecological network will be significantly more connected, resilient, and resistant to interference, the ecological flow transmission will be more efficient.

The paper analyzes the water quality of hydrological resources in the wider area of Tara National Park (NP Tara) in Serbia and the opinions of the local community and the national park visitors about the grade of the possible damage. The pollution level of the Drina River at the Bajina Bašta hydrological station was analyzed using the Water Pollution Index. The results showed that water quality corresponded to classes II (clean water) or III (moderately polluted water) and revealed the presence of organic pollution. In addition, using a survey combined with field research, the perceptions of local inhabitants and national park visitors related to environmental pollution were analyzed. The community believed that tourism does not cause significant damage to the environment. However, the older and more educated groups of residents and visitors had a more critical perception of the environmental impact of tourism. The results also indicated that the perceptions of visitors were mostly in agreement with measured water quality in the Drina River. The findings of this study have important implications for the management of protected areas and future policies related to national parks.

A large-scale energy and chemical industry base is an important step in the promotion of the integrated and coordinated development of coal and its downstream coal-based industry. A number of large-scale energy and chemical industrial bases have been built in the Yellow River Basin that rely on its rich coal resources. However, the ecological environment is fragile in this region. Once the eco-environment is destroyed, the wildlife would lose its habitat. Therefore, this area has attracted wide attention regarding the development of the coal-based industry while also protecting the ecological environment. An ecological network could improve landscape connectivity and provide ideas for ecological restoration. This study took the Ningdong Energy and Chemical Industrial Base as a case study. Morphological spatial pattern analysis was applied to extract core patches. The connectivity of the core patches was evaluated, and then the ecological source patches were recognized. The minimum cumulative resistance model, hydrologic analysis and circuit theory were used to simulate the ecological network. Then, ecological corridors and ecological nodes were classified. The results were as follows: (1) The vegetation fractional coverage has recently been significantly improved. The area of core patches was 22,433.30 ha. In addition, 18 patches were extracted as source patches, with a total area of 9455.88 ha; (2) Fifty-eight potential ecological corridors were simulated. In addition, it was difficult to form a natural ecological corridor because of the area’s great resistance. Moreover, the connectivity was poor between the east and west; (3) A total of 52 potential ecological nodes were simulated and classified. The high-importance nodes were concentrated in the western grassland and Gobi Desert. This analysis indicated that restoration would be conducive to the ecological landscape in this area. Furthermore, five nodes with high importance but low vegetation fractional coverage should be given priority in later construction. In summary, optimizing the ecological network to achieve ecological restoration was suggested in the study area. The severe eco-environmental challenges urgently need more appropriate policy guidance in the large energy and chemical bases. Thus, the ecological restoration and ecological network construction should be combined, the effectiveness of ecological restoration could be effectively achieved, and the cost could also be reduced.

Soil erosion has been considered as the primary cause of soil degradation since soil erosion leads to the loss of topsoil and soil organic matters which are essential for the growing of plants. Land use, which relates to land cover, is one of the influential factors that affect soil erosion. In this study, impacts of land use changes on soil erosion in Pa Deng sub-district, adjacent area of Kaeng Krachan National Park, Thailand, were investigated by applying remote sensing technique, geographical information system (GIS) and the Universal Soil Loss Equation (USLE). The study results revealed that land use changes in terms of area size and pattern influenced the soil erosion risk in Pa Deng in the 1990–2010 period. The area with smaller land cover obviously showed the high risk of soil erosion than the larger land cover did.

PurposeThis paper presents a systematic literature review aiming at analysing how research has addressed performance measurement systems’ (PMSs) ambiguities in the public sector. This paper embraces the ambiguity perspective that PMSs in public sector coexist with and cope with existing ambiguities.Design/methodology/approachThe authors conducted a literature review in Scopus and ScienceDirect, considering articles published since 1985, and the authors selected articles published in the journals included in the Association of Business Schools' Academic Journal Guide (Chartered ABS, 2018). Of the 1,278 abstracts that matched the study’s search criteria, the authors selected 131 articles for full reading and 37 articles for the final discussion.FindingsThe study's key findings concern the elements of ambiguity in PMSs discussed in the literature. The study’s results suggest that ambiguity is still a relevant problem in performance measurement, as a problem that is impossible to be solved and therefore needs to be better understood by researchers and public managers. The analysis allows us to summarize the antecedents and consequences of ambiguity in the public sector.Research limitations/implicationsThe key findings of the study concern the main sources of ambiguity in PMSs discussed in the literature, their antecedents and their consequences. The study results suggest that ambiguity exists in performance measurement and that is an issue to be handled with various strategies that can be implemented by managers and employees.Practical implicationsManagers and researchers may benefit from this research as it may represent a guideline to understand ambiguities in their organizations or in field research. Researchers may also benefit from a summary list of the key issues that have been analysed in the empirical cases provided by this research. Social implicationsThis research may provide insights to limit ambiguity and thus contribute to improve performance measurement in the public sector.Originality/valueThis research presents a comprehensive review on the topic. It provides insight that suggests what future research should attend to in helping to interpret ambiguity, considering also what should be done to influence ambiguity.
