Tdr

"Transfer of Development Rights" (TDR) programs allow local governments to put economic principles to work in encouraging good land use planning. TDR programs most often permit landowners to forfeit development rights in areas targeted for preservation and then sell those development rights to buyers who want to increase the density of development in areas designated as growth areas by local authorities. Although TDR programs must conform to zoning laws, they provide market incentives that make them more equitable (and often more lucrative) for sellers and frequently benefit buyers by allowing them to receive prior approval for their high-density development plans. Since the 1970s when modern TDR applications were first conceived, more than 200 communities in 33 states across the U.S. have implemented TDR-based programs. The most common uses of TDR to date involve protecting farmland, environmentally sensitive land, historic sites, and "rural character," and urban revitalization. Until now, however, there has never been a clearly written, one-volume book on the subject. At last, The TDR Handbook provides a comprehensive guide to every aspect of TDR programs, from the thinking behind them to the nuts and bolts of implementation-including statutory guidance, model ordinances, suggestions for program administration, and comparisons with other types of preservation programs. In addition, six of its twenty chapters are devoted to case studies of all major uses to which TDR programs have been utilized to date, including recent urban revitalization projects that utilize TDR principles.

This framework is a key element in the implementation of TDR’s new strategy. The Strategy covers the six year period from 2018 to 2023 and focuses on improving the health and well-being of those afflicted with infectious diseases of poverty, by fostering an effective global research effort and promoting the translation of innovation to health impact in disease endemic countries. The framework has the following stated objectives: Promote continuous performance improvement through organizational review, learning and informed decision-making; enhance accountability to stakeholders, including beneficiaries, partners and resource contributors; ensure strategic relevance and coherence of TDR's activities to meet the aspirations expressed in the vision, mission and strategy, and their alignment with the 2030 Sustainable Development Goals; and ensure TDR’s performance assessment is harmonized and consistent with international practices.

The report shows progress made on various indicators related to three overarching categories: technical expected results, application of organizational core values and managerial performance. Ultimately, TDR’s outputs and outcomes contribute to health impact, measured through the achievement of Sustainable Development Goals (SDGs) and the World Health Organization’s (WHO) Thirteenth General Programme of Work (GPW13) triple billion targets. Given the adoption of the Sustainable Development Goals by the global community in 2016, TDR developed its 2018-2023 strategy to showcase the Programme’s unique contribution, through research, capacity strengthening and global engagement, to improved health, quality education, enhanced partnerships and other relevant SDG targets guiding international development work over the next 15 years. The Performance Framework (including a revised set of indicators), which is aligned with TDR’s 2018-2023 strategy, the GPW13 strategic objectives and SDG targets, has been in place since 2018.

This report provides an overview of activities in 2020 that demonstrate the impact of research supported by TDR to improve the health and well-being of people burdened by infectious diseases of poverty. This body of research is leading to new solutions for implementation and improved access to existing health solutions. This is the result of TDR’s strategic priorities of research for implementation, strengthening research capacity and global engagement acting in an integrated manner.

GeoMeasurements by Pulsing TDR Cables and Probes examines Time Domain Reflectometry (TDR) research and provides information on its use as a robust, reliable, and economical production tool. Common uses for TDR technology include telecommunications and power industries, but the text examines applications such as measurement of moisture of unsaturated soils; detection of fluids for leak and pollution; measurement of water levels for hydrological purposes; measurement of water pressures beneath dams; and deformation and stability monitoring of mines, slopes, and structures. Chapters discuss: basic physics of signal generation, transmission, and attenuation along the coaxial cable probe designs and procedures for calibration as well as the variation in probe responses to changes in water content and soil mineralogy variations in waveform characteristics associated with cable, deformation, cable calibration, and installation techniques for metallic cables in rock several cases demonstrating the use of TDR cables in soil as well as weathered and soft rock a rationale for the use of compliant cable in soil the use of metallic cable (MTDR) and optical fiber (OTDR) to monitor response of structures sensor/transducer components, connections from the sensors to the TDR pulser/sampler, and system control methods available software for transmission and analysis of TDR signatures The diverse interest and terminology within the TDR community tends to obscure commonalities and the universal physical principles underlying the technology. The authors seek to crystallize the basic principles among the seemingly divergent specialties using TDR technology in geomaterials. By examining varied experiences, GeoMeasurements by Pulsing TDR Cables and Probes provides a synergistic text necessary to unify the field.
