This thesis reports on the slate of the environment(SoE) in Macedonia. Using available data from the specialiied institutions and environmental experts, it shows an accurate picture of the situation with environmental protection in the country. The media addressed include air, water, soil and forests. Also, the social sphere of the environmental Protection is discussed through the review of the natural protection, public participation and the media. The focus of the thesis is on solid waste management. An assessment of the current situation in solid waste management in Macedonia is pesented together with its major components: waste stream composition, collection, transportation, recyclingj, reusing and disposal. Identifying landlilling as the most feasible waste dispoI option, an attempt is made to improve the current solid waste management policy. Supranational policy initiatives as at the EU level contribute to a gradual shift from smaller, uncontrolled landfills, with larger unmonitored environmental and larger quality effects and costs, to larger, generally regional systems with pollution control features, These "modern" landfills are carefully sited, and access and dumping are controlled and monitored. In the light of this, several suggestions are made for improvement of the solid waste management, and for gradual shifting towards integrated solid waste management.

Building Information Modelling (BIM) is a relatively new concept to the UK construction industry. With its inception in recent years, the industry is still coming to grips with its utilisation, with around 54% of projects utilising BIM as of 2014. Due to this, BIM has become an extremely relevant topic within the UK infrastructure and the government has instilled an initiative for all centrally-funded projects to utilise BIM as a design tool. However, an optimal BIM strategy has not yet been developed or utilised for transport infrastructure projects which was the primary rationale for this research project. This paper reviews the current BIM process and the limitations it has and how they can be mitigated and, in turn, the process ameliorated in terms of project cost and time. Geotechnical data integration has the potential to improve the BIM process since most projects do not take below-ground data into account. As a result the primary purpose of this study is specifically concerned with investigating how the integration of geotechnical data into the BIM strategy will be possible and how it can influence the process in a cost- and time-saving manner. A number of methods of integrating geotechnical data into the BIM process were considered and critically reviewed, and the potential application of an optimal method focusing on transportation geotechnics was carried out. The research was carried out using a mixed-method approach utilising both positivist and interpretivist strategies. Specifically, a quantitative analysis of a questionnaire survey on qualified UK engineers with industrial experience was analysed together with an analysis of a geotechnical design and construction case study. The results showed that the geotechnical engineers fully support the integration of geotechnical data into the BIM process, while the majority of them consider that this would provide significant cost and time savings in major infrastructure projects as demonstrated in the case study of design and construction of landslip prevention measures for a failed trunk road embankment in Scotland. Utilisation of current data formats through integration with the above-ground data is recommended for a holistic building information model.

AbstractThe recent flooding in the North–East of Scotland has highlighted issues around climate change due to significant changes in duration, severity and volume of precipitation events. The Planning (PA) and Flood Authorities (FA) often do not have the capacity or resources to review and check the accuracy and robustness of the SUD schemes nor the calculations submitted by developers. This study demonstrates the development and application of an Independent Hydrology Audit (IHA) service aimed at auditing and reviewing 'in principle' planning applications from the aspect of flooding risk to the wider community the development is located within. The output of this service is to establish a more accurate representation of surface water impact from developments through the use of adequate green/blue infrastructure, provide a greater assurance to the communities at risk of flooding, and help the PA and FA meet their statutory obligations at the initial stage of planning.

Nature-based solutions (NBS) for hydro-meteorological risks (HMRs) reduction and management are becoming increasingly popular, but challenges such as the lack ofwell-recognised standardmethodologies to evaluate their performance and upscale their implementation remain.We systematically evaluate the current state-of-the art on the models and tools that are utilised for the optimum allocation, design and efficiency evaluation of NBS for five HMRs (flooding, droughts, heatwaves, landslides, and storm surges and coastal erosion). We found that methods to assess the complex issue of NBS efficiency and cost-benefits analysis are still in the development stage and they have only been implemented through the methodologies developed for other purposes such as fluid dynamics models in micro and catchment scale contexts. Of the reviewed numerical models and tools MIKE-SHE, SWMM(for floods), ParFlow-TREES, ACRU, SIMGRO (for droughts), WRF, ENVI-met (for heatwaves), FUNWAVE-TVD, BROOK90 (for landslides), TELEMAC and ADCIRC (for storm surges) are more flexible to evaluate the performance and effectiveness of specific NBS such as wetlands, ponds, trees, parks, grass, green roof/walls, tree roots, vegetations, coral reefs, mangroves, sea grasses, oyster reefs, sea salt marshes, sandy beaches and dunes.We conclude that themodels and tools that are capable of assessing the multiple benefits, particularly the performance and cost-effectiveness of NBS for HMR reduction and management are not readily available. Thus, our synthesis of modelling methods can facilitate their selection that can maximise opportunities and refute the current political hesitation of NBS deployment compared with grey solutions for HMR management but also for the provision of a wide range of social and economic co-benefits. However, there is still a need for bespoke modelling tools that can holistically assess the various components of NBS from an HMR reduction andmanagement perspective. Such tools can facilitate impact assessmentmodelling under different ...

Such tools can facilitate impact assessment modelling under different NBS scenarios to build a solid evidence base for upscaling and replicating the implementation of NBS.

Nature-based solutions (NBS) are being promoted as adaptive measures against predicted increasing hydrometeorological hazards (HMHs), such as heatwaves and floods which have already caused significant loss of life and economic damage across the globe. However, the underpinning factors such as policy framework, end-users' interests and participation for NBS design and operationalisation are yet to be established. We discuss the operationalisation and implementation processes of NBS by means of a novel concept of Open-Air Laboratories (OAL) for its wider acceptance. The design and implementation of environmentally, economically, technically and socio-culturally sustainable NBS require inter- and transdisciplinary approaches which could be achieved by fostering co-creation processes by engaging stakeholders across various sectors and levels, inspiring more effective use of skills, diverse knowledge, manpower and resources, and connecting and harmonising the adaptation aims. The OAL serves as a benchmark for NBS upscaling, replication and exploitation in policy-making process through monitoring by field measurement, evaluation by key performance indicators and building solid evidence on their short- and long-term multiple benefits in different climatic, environmental and socio-economic conditions, thereby alleviating the challenges of political resistance, financial barriers and lack of knowledge. We conclude that holistic management of HMHs by effective use of NBS can be achieved with standard compliant data for replicating and monitoring NBS in OALs, knowledge about policy silos and interaction between research communities and end-users. Further research is needed for multi-risk analysis of HMHs and inclusion of NBS into policy frameworks, adaptable at local, regional and national scales leading to modification in the prevalent guidelines related to HMHs. The findings of this work can be used for developing synergies between current policy frameworks, scientific research and practical implementation of NBS in Europe and beyond for its wider acceptance.
