ASSESSING SOLAR PHOTOVOLTAIC ENERGY SYSTEMS FOR CROP IRRIGATION1

ABSTRACT: An economic analysis of the profitability of adopting solar photovoltaic energy systems for crop irrigation is undertaken. The economic, technological, and political uncertainties surrounding adoption are discussed with reference to their impact on anticipated profitability. On the assumption that the costs of producing photovoltaic modules follows a learning curve characteristic of other inventions, solar systems are likely to be viable for irrigation in some states by mid to late 1980s. A field test in Nebraska is described.

Surprising cooperation despite apparently irreconcilable differences: Agricultural water use efficiency and CALFED

Much has been said about the need and benefits of consensus building for resolving disagreements about water and environmental management. Less has been said about how to better convene and facilitate those processes. This paper focuses on the latter, examining the challenges and breakthroughs encountered when decision-makers convene consensus building processes that seek an agreement among stakeholders who believe they have “apparently irreconcilable differences.” The research described here analyzes two multi-stakeholder, collaborative processes convened by the CALFED Bay-Delta Program (CALFED) on the issue of agricultural water use efficiency in the Sacramento and San Joaquin river watersheds of California. The first process made very little progress; however, stakeholder representatives in the second were able to forge an agreement that included significant innovation and surprising risk taking by all sides. Analyzing the two processes, this paper shows that the stakeholders, conveners, and facilitators in these processes had to do much more than make the discrete trades across interests envisioned in consensus building theory or reframing as described in theories about conflict and frames. Looking at the data, this paper shows how several concepts from outside consensus building—including boundary objects and interlanguage—along with less well-known concepts and issues within the consensus building literature—bricolage and representation—can provide insights into how the Steering Committee accomplished what it did. This paper introduces these additional concepts, how they mattered in this CALFED process, and suggests a complex set of interrelated insights into how future collaborative and integrative environmental programs can approach the most difficult environmental policy and management conflicts.     

电镀综合废水处理工艺研究

根据一般电镀企业排放废水的实际情况,利用一种新型无机离子交换树脂的高选择性,通过一系列条件及处理工艺研究,确定了一套先进、科学、经济和有效的电镀综合废水处理方案。处理后可实现70%废水循环利用,部分排放废水达到国家排放标准。同时,在处理过程中回收各种贵重金属,且它们有较高的纯度,可达95%以上,以便资源化再利用。该工艺既减少重金属对环境的污染,又可实现水及贵重金属的循环利用,效益显著。
