HYDROLOGICAL UNDERSTANDING AND SOCIETAL ACTION1

ABSTRACT: Hydrology is both an applied practical science and a pure geophysical science. The goal of hydrology, as a geophysical science, is to achieve theories capable of explaining with satisfactory accuracy the phenomena of interest. Through the rapidly accelerating power and versatility of digital computing technology, theory development and application are immensely facilitated via increasingly sophisticated predictive modeling schemes, which are now the principal operating tools both for applied management hydrology and for basic geophysical hydrology. While this approach treats phenomena as classes or generalizations, social and behavioral scientists have long argued that human beings base their actions on percepts, i.e., on the concrete specifics of their experience. Thus, the commonly held ideal of basing policy, decisions, and public actions on the best possible science encounters a conflict in belief systems. A possible resolution of this dilemma lies in the use of observational components, which in concept-centered science serve as data to test or calibrate models. These components also serve as a great repository of natural experience that is closely attuned to the perceptual reality that propels societal action. Landscapes and sediments provide indices of real processes, whose occurrence can be expected by continuity to extend to present and future activity. More attention to research on such indices is warranted as a means of triggering perception-based action by responsible decision-makers. Grounded in reality, and tempered by their intrinsic fallibility, the scientifically powerful conceptual schemes (models) will then serve as guides to further action. The full societal benefit of hydrological science requires a balanced approach in which subdisciplines focused on environmental indices are afforded equal attention to those focused on conceptual idealization.     

EVALUATING THE PERSISTENCE OF RESIDENTIAL WATER CONSERVATION: A 1992–1997 PANEL STUDY OF A WATER UTILITY PROGRAM IN DELAWARE1

This study systematically evaluates residential consumer responses to a utility conservation initiative based on an econometric analysis of a sample of 510 households served by Artesian Water Company, Inc. (New Castle County of Delaware). Using a panel study approach covering the period from 1992 to 1997, this study shows that Artesian's water conservation program has had statistically significant and persistent impacts on residential water consumption.     

Negotiating Indigenous knowledge at the science-policy interface: Insights from the Xáxli’p Community Forest

Despite increasing interest in learning from Indigenous communities, efforts to involve Indigenous knowledge in environmental policy-making are often fraught with contestations over knowledge, values, and interests. Using the co-production of knowledge and social order (Jasanoff, 2004), this case study seeks to understand how some Indigenous communities are engaging in science-policy negotiations by linking traditional ecological knowledge (TEK), western science, and other knowledge systems. The analysis follows twenty years of Indigenous forest management negotiations between the Xáxli’p community and the Ministry of Forests in British Columbia (B.C.), Canada, which resulted in the Xáxli’p Community Forest (XCF). The XCF is an eco-cultural restoration initiative that established an exclusive forest tenure for Xáxli’p over the majority of their aboriginal territory—a political shift that was co-produced with new articulations of Xáxli’p knowledge. This research seeks to understand knowledge co-production with Indigenous communities, and suggests that existing knowledge integration concepts are insufficient to address ongoing challenges with power asymmetries and Indigenous knowledge. Rather, this work proposes interpreting XCF knowledge production strategies through the framework of “Indigenous articulations,” where Indigenous peoples self-determine representations of their identities and interests in a contemporary socio-political context. This work has broader implications for considering how Indigenous knowledge is shaping science-policy negotiations, and vice versa.     

Development of Future Generations： Oriented Virtual Negotiation Support System for Intergenerational Conflict

Intergenerational conflict coordination is the fundamental requirement and core of sustainable development. In this paper, through the analysis of the future generations-oriented management mechanisms for intergenerational conflict, the idea of mechanisms and institution building for the coordination and management of intergenerational conflict is put forward. Furthermore, the future generations-oriented virtual negotiation support system （NSS） for intergenerational conflict is developed, built on the analysis of the process simulation of intergenerational wealth transfer, intergenerational equilibrium allocation of resources, and strategies for the mitigation and avoidance of intergenerational conflict, through the application of advanced IT technology. The virtual NSS for intergenerational conflict is helpful to the practical application of the sustainable development theory; on the other hand, it can be applied directly to the intergenerational equilibrium allocation of resources, national economic accounting, formulation of sustainable development strategies and other urgent national economic and social development issues. Finally, the sustainable development theory can be enriched and extended. Therefore, the development of the future generations-oriented virtual NSS for intergenerational conflict has certain theoretical and practical effects on the theory of sustainable development.     

国际粮食贸易背景下的市场整合与虚拟资源流动——以中国巴基斯坦大米市场为例

贸易自由化和区域经济一体化不仅会通过比较优势整合市场、提升效率,还会带来农产品贸易中虚拟资源的流动。以中国—巴基斯坦大米贸易为研究对象,使用两国大米贸易数据,首先检验中巴粮食市场整合程度,其次分析中巴大米贸易带来的虚拟水和虚拟土地的流动。结果表明：（1）中巴之间大米市场已经高度整合,且价格存在长期均衡,但巴基斯坦大米价格比中国波动大,其对中国大米的价格弹性为1.097;“一带一路”倡议带来了巴方大米价格7.8%的下降,增加了穷人的福利。（2）贸易带来了虚拟水土资源的流动。中国累计从巴基斯坦净进口大米354万t,相当于净进口国内52万hm²、巴基斯坦96.4万hm²耕地,以及国内34.4亿t、巴基斯坦101.7亿t水资源。中国应加大技术支持和扩散的力度,具有促进粮食安全,节约全球资源的意义。     

Conflicts and security in integrated water resources management

Water sector reforms based on the concept of Integrated Water Resources Management (IWRM) are criticized for not considering context, local realities or legitimacy during the implementation of water sector reforms. Universal remedies of IWRM can thus lead to resistance, conflicts and ultimately failures of interventions. This paper examines how conflicts and disharmony can be addressed by IWRM's instruments. It conceptualizes institutional security as a highly relevant issue to be addressed during water management interventions. Further, the paper advocates a reform of the holistic concept of IWRM to incorporate ‘peace and security’ as a new pillar of water management based on a broad understanding of societal goals that are embedded in the principles of good governance and sustainable development. It also reviews recent criticism of and debates in IWRM and explains the advantages of expanding the normative idea behind it.     

Complementary safeguards for robust regional watershed governance in a federation: New York City and its municipal water supply

In federations such as the United States, governments at various levels are experimenting with new watershed governance arrangements to protect water quality for both ecosystem health and human consumption. Such arrangements may bring previously uncooperative governments together to credibly commit to resource protection under the auspices of new and intricate formal institutions. Given the risks of cooperation, theory indicates that a robust arrangement will contain means of holding governing actors accountable to each other. This paper examines a purportedly successful case, the New York City watershed governance arrangement, to identify how safeguards against intergovernmental opportunism promote lasting cooperation. Using the qualitative method of process tracing, this paper finds that the New York City watershed governance arrangement uses structural, judicial, and popular safeguards against opportunistic behaviors by governing actors that might threaten the resource or the arrangement. The results indicate that such safeguards are present and interact with other safeguards and rule institutions at the state and federal level to maintain compliance.     

Environmental Rights: on the Perspective of Harmonious Development between Human Beings and Nature

The idea of environmental rights was first ascertained as a universal concern in the late 20th century and then became a fundamental part of environmental law along with the growth of serious disasters brought by the frequent occurrence of extreme environmental crisis. Generally speaking, the environmental rights safeguard and defend human rights and ultimately facilitate producing better conditions of life on earth by stretching and expanding the theory of traditional human rights. But there are endless debates since environmental rights appeared and various views of environmental rights, such as anthropocentric doctrine and organism's centre doctrine. Differentiated from the traditional research, this article reviewed environmental rights from the perspective of harmonious development between human beings and nature rather than from the perspective of law. Therefore, it is very important to clarify the relationship between human beings and nature based on the environmental rights and to promote the environmental rights to be embodied in the constitution. This article emphasized the importance of the practical significance of environmental rights, and built a concrete structure within the legal system that could promote the transformation of environmental law from ‘should have’ right to practical right, and promote the further development of environmental rights and their weightiness in the legal system.     

Application of Transferable Development Rights in Cultivated Land Protection in China

To analyze current policies on cultivated land protection, this article discusses the application of transferable development rights in cultivated land protection by examining the connotation, operation mechanism, and construction on the market mechanism, benefits driving forces, and expected benefits. The results suggest that economic incentives and fairness have been neglected in previous policies on cultivated land protection. Moreover, the introduction of transferable development rights can not only eliminate the imbalance of interests, but also enhance the incentives for farmers and developers. In addition, it can significantly reduce the fiscal expenditure of the government.
