Investigation and potential analysis of low-slope hilly land resources is a foundational work for carrying out land development and utilization scenically. In this paper, based on status of land use change survey data in 2011 and satellite remote sensing data of study area, at the same time,we combined with the practical situation of study area, by using superposition analysis, spatial clustering and fuzzy comprehensive evaluation, did an investigation to low-slope hilly land resources which slopes between 8 degree and 25 degree, analyzed theoretical potential and actual potential of low-slope hilly development and utilization, in order to provide the basis and reference for land use work. The results of the project show: (1) development potential of low-slope hilly land resources is large; (2) the discrepancy beteen theoretical potential and actual potential is obvious; (3) the strategic of development and utilization must be adjust measures to local conditions, pay equal attention to ecological benefit, social benefit and economic benefit and considerate landscape and ecological balance comprehensively.

<p>Erionite is a naturally-occurring zeolite mineral that has emerged as a well-known health hazard over the last few decades. Human exposure to erionite fibers has been unequivocally linked to malignant mesothelioma, a disease also associated with inhalation of airborne asbestos. Indeed, erionite is now classified by the International Agency for Research on Cancer (IARC) as a Group 1 carcinogen (i.e., carcinogenic to humans), but it appears to be more toxic than asbestos. Since volcaniclastic rocks containing erionite are widely present in New Zealand, there is a concern over potential health issues following inhalation of dust particles in particular areas.  Indeed, New Zealand is one of a number of high-income countries with elevated incidence of malignant mesothelioma (2.6 per 100,000), and this has traditionally been thought to be a result of occupational exposure to airborne asbestos fibers. However, recent cases of malignant mesothelioma have emerged without a known link to asbestos exposure, and in 2015, the New Zealand Government acknowledged that erionite was a more potent carcinogen than asbestos. Despite this, there are no established occupational exposure limits for erionite in New Zealand or globally. We are currently using a multi-methodological approach, based upon field investigation, morphological characterization, scanning electron microscopy (SEM)/energy-dispersive spectroscopy (EDS), Transmission Electron Microscopy (TEM), and X-ray powder diffraction (XRPD) to analyse erionite from sites around New Zealand. Preliminary results are reported here, including erionite from Miocene tuff in Auckland. The erionite appears to be erionite-K. From the dimensional analysis, 45.6% of minerals satisfied the requirements for a respirable airborne fibre (length, L ≥ 5 μm, a diameter, w ≤ 3 μm, and L/w value ≥ 3:1). The presence of this mineral is of concern for risk to human health, especially considering the land development in the Auckland region and the quarries and mining-related activities that are operating in the zeolite host rocks elsewhere in New Zealand. Thus, there is a need for a detailed risk assessment in parts of the country indicative of potential hazard. Further assessments of erionite species, quantification of the potentially respirable airborne fibers, and targeted epidemiological surveillance are planned.</p>

GIS technology can be used to support spatial data collection, management, processing, analysis, modeling and display to solve complex planning and manage problems. [2,3] Plot ratio is an important indicator in the reasonable development and utilization. City land suitability evaluation is the basis of urban land development direction. [1] This paper using superposition analysis module and spatial analysis extension module in ARCGIS10.1 software to volume rate statistics, carry out the city land suitability evaluation, and make the results visualization.

The Relationship

Research in Human Capital land Development (RHCD) is a "Research Annual" which aims at investigating "the relationship between the development and utilization of human capital and the process of economic and social change" (p. vii). This series will consist of interdisciplinary studies which are typically longer than a journal article and shorter than a monograph and will be specifically addressed to "fertility, health, education and manpower, migration and the triangle of equity, distribution and efficiency" (p. vii). Edited by Professor Ismail Sirageldin, this first volume of RHCD has touched on most of these areas. Part I of this volume has three articles under the heading "Health and Fertility". Part II contains five articles under the title "Education and Manpower" and Part III has only one article on "Distribution and Equity"

The City

Tsunami risk assessment was conducted for Niigata City, one of the largest cities facing Japan Sea. Niigata City is known as historical port town developed on a low land formed as the delta by the Shinano River and the Agano River. The city is therefore vulnerable for soil liquefaction. In 1964, the city was devastated by a large earthquake in which soil liquefaction and tsunami worsened the damage. In addition, because of the heavy snowfall in winter, like many coastal cities on the Japan Sea side, the water level rise in the Shinano River in the snow-melt season appears to increase the flooding risk of the harbor area. The harbor is protected by a 4 km long breakwater. This study aims to investigate the tsunami risk of the Niigata City considering the collapse of the infrastructures, the soil liquefaction and the tsunami invasion to rivers in the snow-melt period.Recorded Presentation from the vICCE (YouTube Link): https://www.youtube.com/watch?v=hiBabxOE1Nc
