The use of landslide hazard maps to determine mitigation priorities in a dam reservoir and its protection area

Despite longstanding research on the landslide hazard assessment and mapping, the use this information in regional planning applications remains largely unclear. There is still a need for novel methods to interpret the results of hazard analyses. In this respect, the main research question of this study is how the landslide hazard maps can be evaluated in planning practice. To evaluate this issue, a comprehensive case study was carried out and a new methodology, defining the order of priority for the locations where mitigation measures are applied was developed. The investigations were carried out in the Melen Dam reservoir, which provides potable water to the city of Istanbul, and the dam protection area (Duzce, Turkey) in four main stages: (i) Evaluation of the general characteristics of the study area, (ii) preparation of landslide inventory, (iii) development of landslide hazard model, and (iv) implementation of the results of hazard analyses in planning. As a consequence, a decision support system that can evaluate analytically complicated outputs “P_Combined”, “P_{AL min.}”, and “L_Total” and provide clear decisions “Urgent”, “Primary”, and “Secondary” was suggested. Considering the limited resources available for the mitigation measures, the determination of mitigation priorities for the micro-catchments constitutes the key land-use policy for the protection of the dam reservoir.     

Some Potential Linkages for Input-Output Analysis with Flow-of-Funds

Three major, interrelated accounting statements, at the frontiers of quantitative economic analysis, are three interrelated systems, namely: (1) National income and product accounts (NIPA), (2) The input-output tableaux, (IO), and (3) flow-of- funds accounts (FF). The third-mentioned system is somewhat less available and used in only limited areas of macroeconomic analysis. This paper is mainly concerned with use of FF accounting systems. This system shows where financial resources originate, and where they go in support of real capital formation. In this respect, interest rates and other market-based financial rates are of key importance. While much macroeconomic analysis is based on the rates that fit the yield curve, showing the interest rate structure over various maturities of debt associated with a given degree of risk. In contrast, the FF accounts throw light on the whole spectrum of interest rates, across maturities and debt qualities. For example, in analysis of the real estate market and funding of capital formation there, it is important to have a full understanding of the course of mortgage rates of different maturities and qualities. In short, it is necessary to develop a full appreciation of supply and demand forces in the mortgage market, which often is not obviously related to movements of the operative rate for monetary policy, such as very short-term inter bank rates or call money rates. This paper attempts to provide material from the flow-of-funds accounts that would make it possible to analyze the movement of relevant mortgage rates or whatever other rates are needed to understand the financing of capital formation in real estate.

Examining the policy needs for implementing nature-based solutions in cities: Findings from city-wide transdisciplinary experiences in Glasgow (UK), Genk (Belgium) and Poznań (Poland)

To advance the science and practice of implementing nature-based solutions in cities, it is important to examine the obstacles and provide means to overcome them. This paper presents a conceptual framework of policy needs for analysing the science of nature-based solutions’ implementation and connect it to the practice of their implementation that advances the literature by connecting well-researched gaps to a more innovative action-oriented policy development approach that we argue is required for embedding scaled-up nature-based solutions. We conceptualise and ground the policy needs framework of skills, knowledge and partnerships theoretically in current literature of NBS policy and planning and empirically in three European case study cities: Genk in Belgium, Glasgow in UK and Poznan in Poland. The cross-case study analysis points to the knowledge needs of systems’ thinking and solutions-oriented thinking as paramount for implementing nature-based solutions. Our analysis further points to the skills’ needs of negotiation and collaboration for administrative silo bridging and for forging multi-sectoral partnerships essential for planning, and co-managing NBS. We conclude with three ways forward to addressing the policy needs for implementation: first, cities can invest in tailored and targeted capacity building programs, second, institutional spaces need to be established that allow for collaborative learning through and for partnerships and third, cities need to chart governance innovations that promote evidence-based policy for nature-based solutions’ design and implementation.     

THEORY AND PRACTICE OF DECENTRALIZED PLANNING PROCEDURES

Abstract. The paper surveys the theory of decentralized planning procedures, dealing with price-guided, quantity-guided and mixed procedures. Informational and incentive properties of the various procedures are dealt with, as is the problem of public goods. The practice of planning in the USSR, Hungary and India is also discussed.     

National telecommunications planning in Brazil

During the past 15 years Brazil has undergone a process of rapid modernization in its telecommunications. Starting from a chaotic situation, institutional foundations were established and an ambitious development programme carried out. A fundamental piece of this programme was a planning process that proved to be flexible and adequate to handle the social and economic disparities of the country. The policies that have emerged from the planning process were implemented and provided good economic results and satisfaction to customers.     

城市轨道交通大小交路结合快慢车开行方案优化

城市轨道交通线路可以实行大小交路的开行模式,以克服断面客流不均衡导致的能力浪费,而这种模式使长距离乘客的出行时间增加,可以在列车开行大小交路的基础上考虑开行快慢车。以乘客出行成本与企业运营成本最小为目标,考虑列车停站时间与客流需求的关系,将停站时间纳入乘客出行成本,建立双目标非线性整数优化模型,求解乘客与运营企业的成本博弈均衡点。通过算例验证模型的有效性,结果表明,相对于大小交路嵌套的运营模式,实行"大小交路+快慢车"的运营模式可以有效降低乘客出行成本与企业运营成本。
