Nature conservation efforts set for specially protected areas of Turkey

Environmental pollution and degradation of ecosystems considerably affect the natural resources. The Turkish Government is aware of the importance of the preservation of natural ecology and thereby the environmental conservation of many species in their natural habitat. This paper provides critical assessments of the problems and possible solutions in the identification, implementation and management of the Specially Protected Areas (SPAs) system by giving basic information about stakeholders and their responsibilities that currently offer nature conservation in Turkey. The goals of the article are to analyze how the SPAs interface with the local people, especially the villagers who have dwelt there before SPA designation and how people-SPA conflicts resolved; to show how effective the SPA conservation objectives have been; to outline the significance of informing and empowering people in nature conservation for the protected area management and to show the importance of planning at all levels during protection of the natural, archeological and cultural values of the SPAs.     

CASE STUDIES OF AGRICULTURAL WATER CONSERVATION1

Farmers from four irrigation districts in Texas and California were questioned about water conservation practices they are now using, those they plan to adopt, and potential incentives that government might offer to induce still further water conservation on their part. While responses differed somewhat from place to place and among individual farmers, the general results were: a) farmers reported that “water conservation” is not new to them, it is something they practice regularly; b) recent innovations such as laser controlled land leveling devices have permitted some substantial water use reductions in recent years; and c) even greater incentive mechanisms that government could provide and that farmers would accept as useful incentives, such as long term low interest loans for water saving equipment, would probably not be able to reduce water use in agriculture much further than 15 percent below current levels. It is recommended nonetheless that Federal agencies and local water districts and individuals should nonetheless pursue water conservation training and education programs, demonstrations of conjunctive use and water banking opportunities for water saving, and increased loan programs for installation of water saving equipment.     

秦皇岛市城镇水土保持工作主要做法及成效分析

随着城镇建设的迅猛发展,项目开发建设占用大量具有生态功能的地表,人为造成的水土流失日趋严重,因此做好城镇水土保持工作至关重要。秦皇岛市从2004年起通过制定规划、建立工作体系、强化预防监督、加强宣传等措施,水土保持工作取得了显著成效:提高了全民水保法制观念,规范了城镇建设项目管理工作,城郊水土流失治理度达90%以上,城区碧水工程已基本完成,实施了城市雨水资源利用试点工程,城市区人均绿地面积达到12 m2,森林覆盖率达40%以上。     

新中国70年生态环境建设发展的艰难历程与辉煌成就

中国的生态环境建设,经历了新中国建立之初生产力低下的农耕文明、改革开放后的工业文明、迈向生态文明的三大阶段,每个阶段都有自身的特质、挑战、应对和成效。从1949年到改革开放前,中国整体上表现为农耕文明特征,自然灾害频发、粮食生产短缺、城市化水平低下。为了跳出\"马尔萨斯陷阱\",新中国的缔造者带领人民治理水患,兴修水利,拓荒垦殖,问题得到缓解但没有得到解决,贫困落后依然,没能彻底摆脱\"马尔萨斯魔咒\"。改革开放后,工业化快速推进,城市化加速发展,使农民得以从土地中解放出来,极大地提升了劳动生产力;同时也使土地得以从农民手中部分释放出来,不仅大幅提升了土地资源价值,也使土地得以休养生息自我生态修复。虽然快速的工业化、城市化进程大幅提升了生产力、积累了巨量的物质财富,但是进入21世纪以来,中国的发展逼近工业文明的生态红线、环境底线和资源上线,可持续发展挑战不断凸显。2010年后,中国全面启动生态保护、污染控制和资源节约的转型发展进程,高质量、大力度建设生态文明,推进人与自然的和谐发展。     

节能环保产业政策工具评述与展望

节能环保产业是打赢污染防治攻坚战的重要支撑,也是推动经济发展的新兴绿色动能。本文利用瓦当设计的政策工具三分法,对当前节能环保产业政策工具进行了分类研究。当前,影响节能环保产业政策的工具主要包括管制型工具、经济型工具、信息型工具三个类型。管制型工具包括指标控制、强制性标准和监督考核等;经济型工具包括财政支持、税收优惠、价格政策、金融政策等;信息型工具包括技术推广机制、产品推广机制等。尽管我国已经初步建立了政策支持体系,但当前政策工具仍然存在一系列不足,管制型工具、经济型工具、信息型工具都有较大的改进调整空间,应当进一步形成规范、合理的管制型制度,以普惠为主而非补助为主的经济型制度,以提供信息服务为主的信息型制度,并以此促进节能环保产业健康、有序发展。     

玻璃钢管线在英买力潜山原油集输中的应用

埋地管道的腐蚀是影响油气田地面工程安全运行的重要因素之一,玻璃钢管道的非金属特性根除了腐蚀环境的形成,杜绝了管道腐蚀穿孔事件的发生,降低了污染土壤等环境问题发生的机率,塔里木油田管道服役现状、史密斯公司30a的研究结果对此做了充分的诠释。英—红外输油管道和哈森-威廉姆斯公式分别从实践和理论上展示了玻璃钢管卓越的水力特性,英买力潜山玻璃钢管线具有良好的经济和社会效益。     

Adaptation Bridges and Barriers in Water Planning and Management: Insight from Recent Extreme Droughts in Arizona and Georgia1

Abstract: It is critical to understand the ability of water management to prepare for and respond to the likely increasing duration, frequency, and intensity of droughts brought about by climate variability and change. This article evaluates this ability, or adaptive capacity, within large urban community water systems (CWSs) in Arizona and Georgia. It analyzes interview data on the bridges and barriers to adapting water management approaches in relation to extreme droughts over the past decade. This study not only finds levers for building adaptive capacity that are unique to each state but also identifies several unifying themes that cut across both cases. The interviews also show that a particular bridge or barrier, such as state regulation, is not universally beneficial or detrimental for building adaptive capacity within each state. Such knowledge is useful for improving water and drought management and for understanding how CWSs might prepare for future climate variability and change by removing the barriers and bolstering the bridges in efforts to build adaptive capacity.
