Development of a Model for Enhancing Justice in MPA Designation and Zoning and its Application to Taiwan’s South Penghu Marine National Park

Abstract

Multi-purpose marine protected areas (MPAs) are prevalent world-wide as institutional mechanisms deployed in the marine environment to manage multiple uses, conserve resources and protect ecosystems. Yet some people may experience disadvantage following the implementation of new MPAs. One understudied aspect of MPAs is the distribution of advantages and disadvantages and how best to address the “justice” concerns that they raise. This article identifies a framework of principles, methods and tools to address these concerns. It devises a “MPA justice model” and demonstrates its applicability to a Taiwanese case study. In 2014, Taiwan proclaimed its first multiple-purpose MPA, the South Penghu Marine National Park and the case study shows ways that the MPA’s socio-economic sustainability could have been better accomplished. The article focuses on future MPA establishment that incorporates distributional fairness and procedural legitimacy into MPA site designation and zoning design - but might also be adapted to use retrospectively in MPA review processes.     

How Are Our MPAs Doing? Challenges in Assessing Global Patterns in Marine Protected Area Performance

Without effective management, protected areas are unlikely to achieve the high expectations the conservation and development sectors have for them: conserving biodiversity and alleviating poverty. Numerous marine protected area (MPA) assessment initiatives have been developed at various spatial and temporal scales, including the guidebook How is your MPA doing? These management assessments have been useful to sites to clarify and evaluate their objectives, yet efforts to examine broader regional or global patterns in MPA performance are only beginning. The authors conducted exploratory trend analyses on How is your MPA doing? indicator data collected by 24 MPAs worldwide to identify challenges and areas for future work. Wide variability across sites with regard to the indicators examined and the constructs used to measure them prevented a true meta-analysis. Managers assessed biophysical indicators more often than socioeconomic and governance constructs. Investment by the conservation community to support collecting and reporting high-quality data at the site level would enable a better understanding of the variation in MPA performance, clarify the contribution of MPAs to both biodiversity conservation and poverty alleviation, and help drive better MPA performance. The absence of rigorous and consistent monitoring protocols and instruments and a platform to turn raw MPA monitoring data into actionable information is a critical but under-recognized obstacle to cross-project learning, comparative analyses, and adaptive resource management.

软土地区小型构造物路段纵向差异沉降控制技术研究

针对204国道盐城南段涵洞基底软基处理与相邻路基存在的差异沉降问题,提出纵向差异沉降控制技术,并以离心模拟试验和数值分析为研究手段,模拟了天然地基和水泥搅拌桩地基处理两种模型的沉降。研究结果表明:采用水泥搅拌桩处理涵洞基底软土的沉降量反而大于天然地基,因而建议以浅层换填处理为主,尽量避免深层处理。
