Critical review of Integrated Water Resources Management: Moving beyond polarised discourse

Integrated Water Resource Management (IWRM) emerged as a popular concept in the water sector in the 20th century. From a highly techno-centric approach in the past, it has taken a new turn embracing Habermasian communicative rationality as a place-based nexus for multiple actors to consensually and communicatively integrate decisions in a hydrological unit. The 'how to integrate' approach had remarkable appeal worldwide in promoting authentic participation of all stakeholders. However, critics argue that the domain of water resource management is a political process of contestation and negotiation; the emphasis is on complexities, contextuality, power dynamics and the importance of analysing real world situations. They demonstrate 'how integration cannot be achieved' given the power dynamics in social interactions. These apparently contradictory discourses draw on different theoretical paradigms and polarise the discourse on IWRM, without offering constructive alternatives. To this end, this paper offers an option to complement this polarised discourse by examining 'how integration actually does take place' in a strategic context thereby facilitating consensual decisions to integrate water management for a sustainable future.

Rapid humanitarian assessments and rationality: a value-of-information study from Iraq, 2003-04

Rapid assessments are one of the standard informational tools in humanitarian response and are supposed to contribute to rational decision-making.(1) The extent to which the assessment organisation itself behaves rationally, however, is an open question. This can be evaluated against multiple criteria, such as the cost and value of the information it collects and its ability to adapt flexibly design or samples when the survey environment changes unforeseeably. An unusual data constellation from two concurrent recent (2003-04) rapid assessments in northern Iraq permits us to model part of the actual assessment behaviour in terms of geographical, community and prior substantive information attributes. The model correctly predicts the decisions, in 79 per cent of the 2,425 local communities in focus, that data collector teams in the Emergency Mine Action Survey made to visit or not to visit. The analysis demonstrates variably rational behaviour under conditions of insecurity, repeated regrouping and incomplete sampling frames. A pronounced bias towards very small rural settlements is irrational for the overall results, but may be a rational strategy of individual survey workers seeking to prolong their employment. Implications for future assessments are sketched in the areas of tools for urban surveys, greater adaptability, including early feedback from users, and sensibility to value-of-information concepts.

国家生态文明建设试点示范区指标合理性探讨

环保部于2013年5月23日颁布的《国家生态文明建设试点示范区指标（试行）》（以下简称《指标（试行）》）已实施有9个月。到目前为止,全国已有6批生态文明建设试点地区参照《指标》要求确定生态文明建设目标,编制生态文明规划。然而,实际工作中发现指标体系中部分指标的合理性有待商榷。本文通过对问题指标进行分类探讨,将指标存在的问题分为四大类：指标定义亟待完善、指标标准设定偏高、指标数据获取性差和参考标准有待更新。根据不同类型指标问题的特点,分别对指标进行分析并提出合理的改进和解决方案,为环保部对《指标（试行）》的进一步完善和改进提供了理论依据和思路,对我国生态文明建设工作持续健康发展起到了促进作用。

建设项目水资源论证实例分析

本文以北京市某商业金融项目取水水资源论证为例,从建设项目区域水资源现状、取用水量合理性分析、取用水可靠性可行性分析及退水影响等几个方面对商业建设项目水资源利用情况进行详细论述,对比分析业主提出的取水方案,本次按定额计算所得水量分别较业主所提用水方案减少了29．68％和42．03％。达到了较高的节水水平。最终总结归纳出城市市政自来水项目水资源论证的特点及工作中需要注意的问题,对城市市政自来水取用水水资源论证工作具有一定的指导意义。     

城市绿地生态系统合理供水辨识分析

城市绿地因具有美化环境、降低空气污染、控制城市热岛等作用而日益得到重视。合理的城市生态供水不仅有益于植被的正常生长,对城市水资源合理配置同样具有积极意义。为统筹城市生态与国民经济发展,保证绿地健康,需要合理的绿地供水管理。本文以土壤含水量为标准,根据田间持水量、临界土壤含水量和凋萎系数三个土壤含水量值划分不同等级的绿地需水量,将供水量分为四个等级,建立了城市绿地供水合理性评价模型,为有效辨识供水合理性提供了参照依据。以2009年北京市城市绿地供水为例,进行了供水合理性分析,结果表明,从全年来看,供水基本合理,虽然绿地蒸散发受到一定抑制,但不影响植被生长;从逐月供水来看,个别月份存在供水过少或过多现象,影响植被生长,且不利于水资源合理利用。     

What’s missing from Ostrom? Combining design principles with the theory of sociocultural viability

Since 1990, Elinor Ostrom’s design principles for common property resource (CPR) institutions have been highly influential, offering a counter to pessimistic arguments about resource users’ prospects of cooperating to manage CPRs sustainably. However, the theoretical underpinnings of Ostrom’s theory have been criticised: as unfairly negative towards macro-level interventions; as utilising an overly narrow conceptualisation of rationality; and under appreciative of the role of power. These criticisms are examined using insights drawn from the theory of sociocultural viability (cultural theory, for short), a theory of plural rationality related to context. Utilising the case of Faroese whaling, the research aim is to assess the extent that cultural theory ameliorates criticisms laid at Ostrom’s design principles. It finds that Ostrom’s research trajectory was reaching the limits of methodological individualism’s ability to grasp rational behaviour and suggests the design principles may in effect be integrated with cultural theory.
