Institutional deficiencies and capacity building constraints: the dilemma for environmentally sustainable development in Africa

SUMMARY

The authors question Africa's ability to achieve sustainable development in view of the erosion of its institution building capacity, a problem compounded by the alarming rate of Africa's continuing marginalisation in the world economy. The situation has been provoked by inappropriate domestic policies which have not only compromised Africa's competitiveness, but also made it particularly vulnerable given the increasing globalisation of markets and factors of production. The benefits associated with effective global economic participation transcend direct financial gains and include technology transfers, technical and managerial skills transfers, and other skills transfers associated with the ‘learning and doing’ process. These benefits are instrumental in the development of the economic, administrative, legislative and social institutions that prescribe the organisational and managerial structure of an economy and define its capacity for sustainable growth. In Africa, the absence of such structures has undermined development efforts and created large impoverished populations. But poverty in living standards is not only prevalent, there is also the acute poverty in knowledge and skills which is so damaging to institution building capacity. The socio-economic impact is manifest in dilapidated infrastructure, decaying institutions, the exodus of the professional and managerial cadre, and the almost total disintegration of society. It is within this context that Africa's ability to evolve and effectively manage sustainable development policies is questioned. The study concludes that the continent's capacity to initiate sound environmental and sustainable development policies depends crucially on its ability to develop appropriate and functional institutions.     

Reflections on the ‘sustainable development’ debate

The paper examines the way in which the term ‘sustainable development’ has been used. Beginning with a short review of responses to a publication of the author's on sustainable development, it goes on to explore the different assumptions behind the discussion of the concept, and the different dimensions of sustainability: economic, political and epistemological. It is argued that, like the environment itself, the concept of sustainable development is a contested domain. We can learn from exploring the way the concept is used and contested.     

Linkages among ecotourism,landscape and natural resource management,and livelihood diversification in the region of Suğla Lake,Turkey

The purpose of this study is to evaluate opportunities of the region of Su?la Lake located in Turkey for community-based ecotourism development that enable sustainable landscape and natural resource management as well as livelihood diversification. A participatory research approach was applied by participation of a diverse number of stakeholders (e.g. local communities, local and central governmental bodies and researchers). A set of participatory research tools (e.g. interviews and field surveys), SWOT analysis and the method of Ecotourism Opportunity Spectrum (ECOS) were used to collect and evaluate relevant data. The study consists of four sections. The first section focuses on SWOT analysis by which the advantages and disadvantages of the study area for ecotourism development were examined. In the second section, the most suitable villages for ecotourism development were examined by adapting the method of ECOS based on the 18 parameters by using 1–4 score system. Accordingly, the most suitable five villages for ecotourism development were determined. Major natural and cultural ecotourism resources (e.g. diversity of landforms, spectacular landscapes and traditional lifestyle) of the study area were examined in the third section. In the fourth section, the ecotourism-based livelihood and relevant core capitals were evaluated according to 1–4 score system for the five villages. We hope that the outcomes of this study can draw attention of planners and policymakers to the role of ecotourism for sustainable landscape and natural resource management as well as livelihood diversification in the region and elsewhere.     

Capacity building for sustainable development: some Mexican perspectives

A broadly defined scientific Capacity Building (CB) for Sustainable Development (SD) is needed all around the world, and the development of innovative capacities in the developing countries is a priority. For this, first we need to know how this concept is applied in some developing countries. In this paper we present some Mexican experiences in the field of capacity building for sustainable development. The main problems are the monodisciplinary training of the specialists, the absence of a sound policy for promotion, career development and assessment of researchers, as well as of their projects when they are interdisciplinary and development-oriented. The main proposals to solve these problems are the creation of mechanisms that foster and legitimize interdisciplinary work; a decentralized planning process with the specific objective of establishing the needs and orientations on a regional basis; provide resources to long-term projects, and finally, consensus on asking international funding agencies for stronger support for public higher education institutions in developing countries in order to increase and strengthen their capacity for education and research in general, and in the field of SD in particular.     

基于SPSS的苏北地区可持续发展能力空间分异研究

以区域可持续发展能力建设为切入点,结合苏北地区的实际,建立适合该地区的可持续发展能力评价指标体系,然后运用SPSS软件的因子分析和聚类分析的方法,对苏北地区可持续发展能力进行综合评价。结果表明,区内各县市可持续发展能力差异较大,但其空间分异呈现出某些特征:经济可持续发展能力呈现由地区东南部向中间递减的“一”字型空间格局;资源环境可持续发展能力呈现由地区中部分别向东、向西递减的“凸”字型空间格局;社会可持续发展能力呈“M”字型空间格局;综合可持续发展能力呈“H”字型空间格局;以中心城市为核心,可持续发展能力向周边呈辐射状递减趋势。根据这些空间分异特征,提出了一些促进苏北地区可持续发展能力建设的建议。     

生态承载力研究进展

从生态承载力角度研究区域资源-生态-环境问题,是当今生态学、地理学和经济学等学科研究的热点与前沿领域之一。在调研现有研究成果基础上,阐述了承载力的起源、演化与发展以及国内外研究进展,对生态承载力的概念、研究方法、研究趋势及其与可持续发展的关系等进行了评述。生态承载力内涵可以概括为“特定时间、特定生态系统自我维持、自我调节的能力,资源与环境子系统对人类社会系统可持续发展的一种支持能力以及生态系统所能持续支撑的一定发展程度的社会经济规模和具有一定生活水平的人口数量”。今后生态承载力研究的发展方向是:研究对象趋向多元化,研究领域呈现交叉综合趋势;生态脆弱带将继续成为研究的热点地区;研究重点将继续向动态模拟化方向发展;新方法、新技术手段将不断应用于生态承载力研究。     

试论我国乡村景观的特点及乡村景观规划的目标和内容

乡村景观是指乡村地域范围内不同土地单元镶嵌而成的嵌块体，以农业特征为主，是人类在自然景观的基础上建立起来的自然生态结构与人为特征的综合体。随着城镇化进程的加快，我国乡村景观将面临着前所未有的变化。如何保护乡村景观的特色和完整性，充分挖掘乡村景观的生态和文化旅游价值，使其形成高效、完整并具有传统特色的多功能的乡村地域，是21世纪乡村可持续发展的重要任务之一。文章首先界定了乡村景观的概念和内涵，指出了我国乡村景观的主要特征；然后探讨了乡村景观规划与土地利用之间的关系，认为乡村景观规划是未来我国乡村持续发展的重要手段；最后系统地讨论了我国乡村景观规划的目标和内容。

海南与其他6个生态示范省的经济发展及区域可持续发展能力比较

建设生态省是实施区域可持续发展的一种有效组织形式。本文就国家环保总局批准的七个生态示范省的经济发展及区域可持续发展能力进行比较,发现七省的经济发展现状及区域可持续发展能力在全国31个地区中属于中上水平,均有创建生态省的本底条件,但区域可持续发展各方面的能力极不平衡,各省要从实际出发,扬长避短,因地制宜,探索具有本地特色的生态省建设的新路子。     

生态承载力的概念及其研究方法

生态承载力研究是可持续发展科学领域关注的热点问题,是判定可持续发展的重要分析手段,对生态承载力的概念和评价方法的研究有利于可持续发展科学的发展与完善。对国内外相关研究中的生态承载力概念进行了总结,并深入探讨了不同学者对于生态承载力概念达成的共识及存在的分歧,在此基础上提出了生态承载力概念的内涵。依据生态承载力评价的思路,将国内外生态承载力评价方法分为3类,第1类是指标体系评价法,第2类是以能量、物质流为基础的产品周期评价,第3类是综合性评价。上述评价方法在处理复杂系统问题上都有各自的优缺点,需要评价者根据评价目的采用互补的方式对方法进行集成,加强综合集成的方法在生态承载力评价中的应用。最后,结合生态承载力研究的发展趋势,分析了目前生态承载力研究的不足,提出了生态承载力中主动因子与被动因子、生态承载力预测及其与区域规划的结合、经济发展和科技进步对生态承载力的影响、生态承载力方法改进等亟待开展的研究内容。
