Challenges in developing and implementing a decision support systems (ETÇAP) in forest management planning: a case study in Honaz and Ibradı, Turkey

Decision support systems (DSSs) are indispensable tools in preparing a forest management plan for a better combination of multiple forest values. This study attempted to develop and explain a stand-based forest management DSS (Ecosystem-based multiple-use forest planning [ETÇAP]) comprising a traditional simulation, linear programming (LP), metaheuristics and geographic information system. The model consists of five submodels; traditional management approach to handle inventory data, an empirical growth and yield model, a simulation to conceptualize management actions, a LP technique to optimize resource allocation and a simulated annealing approach to directly create a spatially feasible harvest schedule. The ETÇAP model has been implemented in a comparative two case study areas; Denizli–Honaz and Akseki–Ibrad?. Both simulation and optimization models outperformed to the traditional management plan. The periodical change of growing stock, allowable cuts, carbon sequestration and water production are used as performance indicators. The results showed that more amount of wood could be harvested over time compared to traditional level of harvesting. It could be concluded that various management strategies allowed managers to stimulate more decision options for better outputs through intertemporal trade-offs of management interventions as the model provided tools to quantify forest dynamics over time and space. Challenges exist to establish the functional relationships between forest structure and values for better quantification and integration into the management plans.

Determining spatial feed distribution in sea cage aquaculture using an aerial camera platform

Within this paper we describe an unmanned aerial vehicle (UAV) based method to estimate the spatial feed pellet distribution in salmon fish-cages and exploit it within a case study to determine the radial pellet distribution for different rotor spreaders and blower configurations. Compared to previously used methods, capturing pellets thrown from a rotary feed spreader in rows of Styrofoam boxes, the UAV based method is simpler and faster to setup and allows to cover a larger portion of the sea cage surface area. We compare results obtained with the Styrofoam box method with results we obtained by an automatic analysis of aerial videos taken by the UAV during feeding experiments. The employed method helps to gain insight into the spatial feed pellet distribution in full-scale salmon fish-cages where the feeding pipe and actual fixation of the spreader may influence the dynamic behaviour of the feeding system. This can also be seen as a step towards a continuous measuring of the feed pellet distribution, particularly in view of possible future feeding systems that may allow to adapt the feed pellet distribution to the actual fish distribution.

国内外应对气候变化立法研究进展

为了积极应对气候变化,促进低碳经济发展,分析了当前应对气候变化立法方面的研究进展,认为尽管取得了一定进展,但现有法律既不能满足我国气候外交的需求,也不足以担当气候治理的重任,我国还缺乏系统性专门性的应对气候变化法律.为了应对气候变化的挑战,必须充分整合国内外应对气候变化立法方面的科技资源,以保证我国气候外交和气候治理战略的科学性.     

甘肃省农村信息化发展水平探讨

农村信息化是社会主义新农村建设的重要内容,是解决"三农"问题的突破口。对于欠发达的甘肃农村经济,近年来虽然取得很大进步,但总体水平还不高,与发达地区的差距还很明显。在客观数据的基础上,基于因子分析方法建立了综合评价农村信息化水平的模型,直观的比较了各省市的农村信息化水平,认为信息资源的利用情况和信息基础设施建设的差异是评价农村信息化水平的决定因素,提高农村信息化水平必须从这两方面着手,切实可行的推进甘肃农村信息化的发展。
