    Organic agriculture: opportunities and challenges

    Get PDF
    The organic movement may have gained a place in the spotlight of the mainstream media now, but it has not been like that for long. Since the 1950s, organic farmers operating at a grass roots level have devised, tested and shared production methods. They have codified a set of ideals into a pioneering best practice agricultural management system that addresses multiple community values. Niche markets have gradually been created, commonly based on trust and goodwill (formal certification did not begin until the 1960s and 1970s), and often using novel direct marketing strategies such as box schemes and community supported agriculture. After many years of consumers having to hunt around for their organic produce from several suppliers, perhaps directly from the farmer, the task is now a lot easier with specialist food shops and organic shelf space in supermarkets, in the industrialised world at least. Global links have been forged in all continents as organic agriculture has been seen to be an effective rural development option

    NASA space station automation: AI-based technology review

    Get PDF
    Research and Development projects in automation for the Space Station are discussed. Artificial Intelligence (AI) based automation technologies are planned to enhance crew safety through reduced need for EVA, increase crew productivity through the reduction of routine operations, increase space station autonomy, and augment space station capability through the use of teleoperation and robotics. AI technology will also be developed for the servicing of satellites at the Space Station, system monitoring and diagnosis, space manufacturing, and the assembly of large space structures

    Ecolabelling and Fisheries Management

    RAFMS (Rapid Appraisal of Fisheries Managment Systems) designed by ICLARM is a semistructural research tool designed to quickly document and evaluate exisiting local-level fisheries management systems in a given coastal community. The results of RAFMS will provide direction for undertaking more formal research or quantitative surveys to describe institutional arrangements and performance. RAFMS is suited to the village level, or to a cluster of villages within a defined marine unit such as a bay. It's emphasis is on the evaluation of the rights and rules system governing the use of the fisheries resources at the local level. The approach is also participatory because it is designed for the joint use of RAFMS practitioners and local researchers in collaboration with local fishing communities. The mode of community participation, however, is consultative. This Version 1 of the guide was published with the anticipation of future feedback. Version 1 had been tested for two years prior to being published in collaboration with ICLARM's research partners at: Ulugan Bay and Binunsalian Bay in Palawan, Asia (Southeastern)-Philippines; and Nolloth Village at Saparua Isalnd in Indonesia

    Data Cleaning: Problems and Current Approaches

    Get PDF
    We classify data quality problems that are addressed by data cleaning and provide an overview of the main solution approaches. Data cleaning is especially required when integrating heterogeneous data sources and should be addressed together with schema-related data transformations. In data warehouses, data cleaning is a major part of the so-called ETL process. We also discuss current tool support for data cleaning

    Lucene4IR: Developing information retrieval evaluation resources using Lucene

    Get PDF
    The workshop and hackathon on developing Information Retrieval Evaluation Resources using Lucene (L4IR) was held on the 8th and 9th of September, 2016 at the University of Strathclyde in Glasgow, UK and funded by the ESF Elias Network. The event featured three main elements: (i) a series of keynote and invited talks on industry, teaching and evaluation; (ii) planning, coding and hacking where a number of groups created modules and infrastructure to use Lucene to undertake TREC based evaluations; and (iii) a number of breakout groups discussing challenges, opportunities and problems in bridging the divide between academia and industry, and how we can use Lucene for teaching and learning Information Retrieval (IR). The event was composed of a mix and blend of academics, experts and students wanting to learn, share and create evaluation resources for the community. The hacking was intense and the discussions lively creating the basis of many useful tools but also raising numerous issues. It was clear that by adopting and contributing to most widely used and supported Open Source IR toolkit, there were many benefits for academics, students, researchers, developers and practitioners - providing a basis for stronger evaluation practices, increased reproducibility, more efficient knowledge transfer, greater collaboration between academia and industry, and shared teaching and training resources

    Ecolabelling and fisheries management

    National and intergovernmental regulation of fisheries has not prevented many failures of fisheries management around the world. New approaches to improving the environmental sustainability of fisheries have included the certification of fisheries harvested by sustainable means, and the ecolabelling of fish and seafood products from certified fisheries. The intention is to use the power of markets as an incentive to induce more sustainable fisheries. To date, only a relatively small number of fisheries have been certified, and these have been predominantly in developed countries. Critiques from developing countries of ecolabelling, as currently formulated, focus on five general areas: (1) legitimacy and credibility; (2) a mismatch between certification requirements and the reality of tropical small-scale fisheries; (3) potential distortions to existing practices and livelihoods; (4) equity and feasibility; and (5) perceived barriers to trade. This paper reviews these developing country concerns on the basis of already certified fisheries, and on experiences from forestry, aquaculture and the aquarium industry, and also examines precedents and trends in international environmental and trade issues. It suggests that ecolabelling as currently practiced is unlikely to be widely adopted in Asian countries. Certification may have sporadic success in some eco-conscious, or niche, markets but it is unlikely to stimulate global improvement of fisheries management.Fishery management, Eco-labelling, Certification, Fishery regulations, Sustainability, Developing countries

    The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

    Salient Trends in Organic Standards: Opportunities and Challenges for Developing Countries

    Get PDF
    This paper presents an overview of the fundamental issues in the production, trade and regulation of organic products. It notes the changing consumer and trade environments that are driving organics beyond the realm of niche products toward an increasingly relevant position among other important agricultural standards. Rather than a comprehensive analysis it outlines key elements that are most relevant to developing country producers including the likely impacts of adopting organics and the salient trends drawing from recent empirical research and the current literature on the subject. Finally, this document briefly assesses the significant constraints and opportunities facing the sector in order to draw some practical policy and investment conclusions
