Key Informant

Natural areas are increasingly fragmented and degraded globally due to increasing anthropogenic pressure. Linear infrastructures such as roads, railways, canals, and transmission lines are major causes for such fragmentation resulting in population isolation, habitat connectivity loss, and gene pool shrinkage. Various mitigation measures are adopted to minimize such effects. The first such mitigation measure (an underpass) has been constructed along the Narayanghat – Ramnagar, and Ramnagar – Jugedi section of the Narayanghat-Muglinroad (section connecting two national highways; Prithvi and Mahendra highway). The effectiveness of these underpasses was assessed using a camera trap picture of wildlife movement during March and April 2019. Key informant interviews (n=14) were also carried out to understand the abundance of recorded species in the local forest. With 37 trap nights of sampling effort, seven mammalian species were recorded and among them, wild boar was found with the highest independent images (35). A total of 31 independent images (70.4 %) captured during the night hours showed that manmade underpasses were used more during the night. Confirmation of usages of these underpasses supports the study to indicate the necessities of underpasses while constructing roads that pass and traverse the wildlife habitat.

The Impact

The road network is a land transportation infrastructure that plays an important role in the transportation sector, especially for the balance of the distribution of goods and services, both from other regions. In this study, an analysis was conducted to find out how the influence of heavy vehicle volume increase on the service life of the road, while the method used was Bina Marga, the study was conducted by taking a case study on the Hera road section until Dili. This research is expected to find out how the service life of the road if the volume of heavy vehicles continues to increase. If the% of heavy vehicles increases, the thickness of the required surface layer will also be even greater. When% of vehicles or carrying heavy traffic loads are increased, the thickness of the existing layer cannot meet, because the calculation results with% of heavy vehicles increase by 10%, surface thickness 17.2 cm / This will cause the service life of the road to decrease because it is confirmed that the road will be damaged before the service period ends due to excessive load increase in heavy vehicles.

Road Section

Landslides and roadside slope failures resulting in road blockage, damage and economic losses are regular phenomena in the mountain regions of Nepal. Road construction in the northern belt of Himalaya is a challenging task, mainly due to the anticipated geo hazard in the region and remoteness of the area. The situation is often intensified in the region due to limited engineering geological and geotechnical information. The geo disaster risk further increases due to road construction. Geo hazard assessment is prerequisite to have best road alignment in mountain areas that are basically landslide-prone in many cases. The products of space science (like satellite imageries) could be a better choice for this purpose because of availability of high resolution imageries and their ready availability. The data acquired from space borne technology can be used to better assess the geological hazard condition along the road alignment. The present paper focuses to this aspect with the case study of a road section of Taplejung-Olangchunggola- Nangma, reaching the Nepal-Tibet border. The geo hazard assessment along the road corridor has been carried out through extracting the relevant information from satellite images in addition to the use of available secondary information as well as field study. A GIS database has been developed with the required information, which was used to prepare various thematic layers (like geology, drainage density, slope, aspect, rainfall), followed by further analysis. The suitability of the existing alignment has been evaluated with respect to the geo hazard condition along the road alignment.

The Relationship

This article attempts to seek the understanding and perception of Chepang on the practices of khoriya cultivation. It tries to explain the relationship of Chepang people to their traditional khoriya land by assessing the socio-cultural and economic importance in their life. Chepang’s indigenousness is closely connected to khoriya cultivation and the land is their ethnic and indigenous identity. The practices of shifting cultivation have to be understood holistically within the domain of social and cultural analysis. However, their relationship to their khoriya land and the agricultural practice cannot be understood only in measurable indicators and specific manners. For Chepang, shifting cultivation is a good ecological adaptation to their surrounding environmental settings based on indigenous knowledge and skills developed in the particular geographical setting on basis of trial and error. To understand culture, history and everyday life of the Chepang, knowing all about their traditional agricultural practice i.e. shifting cultivation is very significant.

The Eu

The European Parliament and the European Council have adopted the Directive 2008/96/EC relating to the safety of traffic infrastructure. This Directive binds the EU Member States to implement the guidelines on roads comprising the parts of the Trans-European traffic network, regardless of the stage those roads are in. EU Member States have a possibility to adopt the guidelines and regulations from the Directive and build them into the national regulations on parts of the roads that are not a part of the Trans-European roads. Based on the facts stated above, there is a research problem in a form of a question “Can the Directive 2008/96/EC be applied in the traffic in Bosnia and Herzegovina?” i.e. are its guidelines implemented as a manner of approximation with the EU regulations, and what are the effects of its implementation. This is a traffic problem in its nature, closely related to road traffic safety, and we find the answer to the research problem in theoretical and empirical research in this area.
