Testing Hypotheses for the Success of Different Conservation Strategies

Abstract:  Evaluations of the success of different conservation strategies are still in their infancy. We used four different measures of project outcomes—ecological, economic, attitudinal, and behavioral—to test hypotheses derived from the assumptions that underlie contemporary conservation solutions. Our hypotheses concerned the effects of natural resource utilization, market integration, decentralization, and community homogeneity on project success. We reviewed the conservation and development literature and used a specific protocol to extract and code the information in a sample of papers. Although our results are by no means conclusive and suffer from the paucity of high-quality data and independent monitoring (80% of the original sample of 124 projects provided inadequate information for use in this study), they show that permitted use of natural resources, market access, and greater community involvement in the conservation project are all important factors for a successful outcome. Without better monitoring schemes in place, it is still impossible to provide a systematic evaluation of how different strategies are best suited to different conservation challenges.     

高效湿式脱硫除尘一体化装置的研究

针对我国目前SO2和颗粒状污染物（特别是PM10）污染严重的现状，开发了一种高效湿式除尘脱硫一体化装置。试验表明，本装置的平均除尘率和平均脱硫率分别为97.6%和88.1%。并且对细小颗粒物具有良好的捕集效果。与国内同类装置比较，本装置能在较小的液气比（0.11-0.34L/m^3)和阻力（＜900MPa)条件下实现良好的除尘和脱硫，适合于工业锅炉和窑炉的烟气治理。     

植物净化床对双龙湖水体有机污染物的去除效果分析

通过对双龙湖A、B两座植物净化床2004年6月至2005年5月间的进出水监测数据进行分析,确定植物净化床对水体有机污染物去除效果的年际变化。结果表明,A、B两座植物净化床对CODMn、总磷(TP)、氨氮(NH3-N)、总氮(TN)均有很好的去除效果,对CODMn的平均去除率为71.41%和72.58%,出水水质平均为2.47和2.36mg·L-1;TP的平均去除率为83.01%和84.70%,出水水质平均为0.033和0.037mg·L-1;NH3-N的平均去除率为89.28%和90.30%,出水水质平均为0.125和0.141mg·L-1;TN的平均去除率为60.90%和65.48%,出水水质平均为1.204和1.268mg·L-1。对硝态氮(NO3-N)的去除效果较差,平均去除率为6.91%和32.47%,出水水质平均为0.407和0.637mg·L-1。分析CODMn、TP、NH3-N、TN和NO3-N去除效果的季节变化发现,各指标的去除效果和季节变化有一定关系。最后,作者对植物净化床的运行控制提出了相关建议。

Coupling climate and economic models in a cost-benefit framework: A convex optimisation approach

In this paper, we present a general method, based on a convex optimisation technique, that facilitates the coupling of climate and economic models in a cost-benefit framework. As a demonstration of the method, we couple an economic growth model à la Ramsey adapted from DICE-99 with an efficient intermediate complexity climate model, C-GOLDSTEIN, which has highly simplified physics, but fully 3-D ocean dynamics. As in DICE-99, we assume that an economic cost is associated with global temperature change: this change is obtained from the climate model, which is driven by the GHG concentrations computed from the economic growth path. The work extends a previous paper in which these models were coupled in cost-effectiveness mode. Here we consider the more intricate cost-benefit coupling in which the climate impact is not fixed a priori. We implement the coupled model using an oracle-based optimisation technique. Each model is contained in an oracle, which supplies model output and information on its sensitivity to a master program. The algorithm Proximal-ACCPM guarantees the convergence of the procedure under sufficient convexity assumptions. Our results demonstrate the possibility of a consistent, cost-benefit, climate-damage optimisation analysis with a 3-D climate model.
