INTRODUCTION 1. This summary environmental impact assessment (SEIA) describes the possible environmental impacts of the construction and operation of the proposed Western Guangxi Roads Development Project (the Project) in the People’s Republic of China (PRC), and recommends measures to mitigate the adverse impacts. The SEIA conforms to the Environmental Assessment Guidelines (2003) and the Environment Policy (2002) of the Asian Development Bank (ADB). It rates the Project as category A, according to ADB’s environmental classification criteria. This SEIA is based on (i) the environmental impact assessment (EIA) report on the Longlin–Baise Road1 prepared by the Guangxi Zhuang Autonomous Region Communications Department (GCD),2 (ii) feasibility study reports on the Longlin–Baise Road prepared by GCD3 and the related official documents,4 (iii) the EIA report5 on the Tianlin–Leye local road prepared by GCD,6 (iv) Environmental Impact Report Tables7 for four other local roads,8 (v) the feasibility study on the local roads, (vi) the master plan for the construction of rural bus stations by GCD and (vii) the work done by the technical assistance consultants under the project preparatory technical assistance.9 2. The EIAs complied with the relevant laws, regulations, and standards of the PRC, including (i) the Technical Guidelines on Environmental Impact Assessment and Environmental Protection Standards of the PRC (September 1993), and (ii) the Standards for Environmental Impact Assessment of Highway Construction Projects, Ministry of Communications (January 1996). II. THE PROJECT 3. The Project will help promote sustainable economic growth and poverty reduction in Guangxi as a whole and the project area in particular by (i) making road transport more efficient and safe; (ii) improving the road transport network by building the Baise-to-Longlin (on the Guizhou border) section of road in the east–west corridor, one of eight high-priority western corridors; and (iii) giving poor rural and minority villages better access to income-generating opportunities and social services. 1 China Hydro Power Consultant Group Design and Research Institute. 2006.

  • Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor?
    DOI:http://dx.doi.org/10.7314/APJCP.2015.16.8.3579 Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor? RESEARCH ARTICLE Anisotropic Patterns of Liver Cancer Prevalence in Guangxi in Southwest China: Is Local Climate a Contributing Factor? Wei Deng1&, Long Long2&*, Xian-Yan Tang3, Tian-Ren Huang1, Ji-Lin Li1, Min- Hua Rong1, Ke-Zhi Li1, Hai-Zhou Liu1 Abstract Geographic information system (GIS) technology has useful applications for epidemiology, enabling the detection of spatial patterns of disease dispersion and locating geographic areas at increased risk. In this study, we applied GIS technology to characterize the spatial pattern of mortality due to liver cancer in the autonomous region of Guangxi Zhuang in southwest China. A database with liver cancer mortality data for 1971-1973, 1990-1992, and 2004-2005, including geographic locations and climate conditions, was constructed, and the appropriate associations were investigated. It was found that the regions with the highest mortality rates were central Guangxi with Guigang City at the center, and southwest Guangxi centered in Fusui County. Regions with the lowest mortality rates were eastern Guangxi with Pingnan County at the center, and northern Guangxi centered in Sanjiang and Rongshui counties. Regarding climate conditions, in the 1990s the mortality rate of liver cancer positively correlated with average temperature and average minimum temperature, and negatively correlated with average precipitation. In 2004 through 2005, mortality due to liver cancer positively correlated with the average minimum temperature. Regions of high mortality had lower average humidity and higher average barometric pressure than did regions of low mortality.

    Resettlement Planning Document Summary Resettlement Plan Document Stage: Draft for Consultation Project Number: 39149 April 2007 PRC: Western Guangxi Roads Development Project Prepared by the Government of Guangxi Autonomous Region for the Asian Development Bank (ADB). The summary resettlement plan is a document of the borrower. The views expressed herein do not necessarily represent those of ADB’s Board of Directors, Management, or staff, and may be preliminary in nature. SUMMARY RESETTLEMENT PLAN A. Status of the Resettlement Plan 1. The proposed Western Guangxi Roads Development Longlin-Baise Expressway) Project includes the construction of (i) a 177 kilometer (km) expressway from Longlin County (Guizhou Province border) to Baise City (Youjiang District), (ii) connector roads with a length of 28.6 km, (iii) a rural roads component comprising rehabilitation of 6 sections with a total length of 310 km, (iv) upgrading 750 km of village access roads, and (v) 50 township bus stations. One Resettlement Plan (RP) covers the expressway and related connector roads, interchanges, toll stations, and service areas. Other RPs cover the 6 local roads. A Resettlement Policy Framework and Procedural Guideline addresses the village roads and the township bus stations. The Expressway is based on preliminary design while the local roads are based on feasibility level study. The location of towns where bus stations will be built is known, but sites have not been decided so far. The village roads will be selected during implementation. Prior to commencement of land acquisition and house demolition, Guangxi Communications Department (GCD) will update all RPs based on detailed measurement survey and submit them to ADB for approval.

The State Council officially replied the “planning framework of comprehensive controls for karst rocky desertification regions” during 11th Five Year Plan. The counties in Guangxi appointed by the planning framework were taken as the study objects. First, the index system of suitability assessment was established and the fuzzy comprehensive assessment was conducted. The control patterns were regionalized by a bottom up method. Second, the karst rocky desertification control patterns under different geographic background were collected and summarized. The control patterns were generalized by a top down method. Finally, the assessment results of the two methods were compared and adjusted. Then, the karst counties of Guangxi were regionalized and the suitable control patterns for karst counties were determined. Introduction In Guangxi, some successful rocky desertification control patterns and techniques have been formed. But these methods are developed under different ecological, social and economic conditions [1-2]. These patterns have promotional value theoretically, but their application scopes still need to be discussed [3].

Monthly and seasonal rainfall (1963-2017) for a typhoon-influenced area in a Chinese karst basin Chongxun Mo1, 2, 3, Yuli Ruan1, 2, 3,*, Jiaqi He1, 2, 3, Guikai Sun1, 2, 3, Juliang Jin4 1 College of architecture and civil engineering Guangxi University, Nanning, China 5 2 Key Laboratory of Disaster Prevention and structural Safety of Ministry of Education, Nanning, China 3 Guangxi Key Laboratories of Disaster Prevention and Engineering Safety, Nanning, China 4 School of Civil Engineering, Hefei University of Technology, Hefei 230009, China Correspondence to: Yuli Ruan ([email protected]) Abstract. Under the dual influence of global warming and typhoon weather, the characteristics of monthly and seasonal 10 rainfall become more complicated and extreme, leading to more frequent rainfall and flood disasters. The objective of this study is to propose a framework for analysing the characteristics of rainfall and its correlation with typhoons. The proposed framework consists of an analysis of inner-annual distribution, inter-annual variation as well as correlation between rainfall and typhoons. Especially, a DVM method is proposed to compute the rationality and reliability of the abrupt change time analysis. Finally, the proposed framework was successfully implemented using a 55-year time series (1963-2017) of rainfall 15 data recorded by 12 rain gauges in Chengbi River Basin (South China).The results are as follows. (1) The relative variability of monthly rainfall is relatively large (above 30%), and the rainfall tends to be centralized, and is mainly concentrated in July.
