Costs and benefits of spatial data accuracy on comprehensive conservation planning assessments - A conceptual approach

The planning of protected habitat networks to safeguard global biodiversity requires substantial knowledge on exposure, services, and functions of ecosystems. Spatial-ecological datasets contain important information for the adequate assessment of spatial economic and ecologic interdependencies. However, these data are still lacking in many places. Comprehensive earth observation can play an important role in the provision of such data but it also involves costs. Cost-benefit analyses may answer the question whether the preparation of such comprehensive spatial data is worthwhile and may help to find the appropriate data resolution for conservation planning questions under consideration of costs. We compare several wetland data sets on global, national, and regional scale according to their spatial accuracy of wetland distribution and the costs of data survey, monitoring, and supply. The spatial data are integrated into bioeconomic land use models of different scales to assess benefits and uncertainties of increased data resolution and accuracy

The Value of Global Earth Observations

Humankind has never been so populous, technically equipped, and economically and culturally integrated as it is today. In the twenty-first century, societies are confronted with a multitude of challenges in their efforts to manage the Earth system

Tapping into non-English-language science for the conservation of global biodiversity.

The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. However, non-English-language science is expected to bring unique and valuable scientific information, especially in disciplines where the evidence is patchy, and for emergent issues where synthesising available evidence is an urgent challenge. Yet such contribution of non-English-language science to scientific communities and the application of science is rarely quantified. Here, we show that non-English-language studies provide crucial evidence for informing global biodiversity conservation. By screening 419,679 peer-reviewed papers in 16 languages, we identified 1,234 non-English-language studies providing evidence on the effectiveness of biodiversity conservation interventions, compared to 4,412 English-language studies identified with the same criteria. Relevant non-English-language studies are being published at an increasing rate in 6 out of the 12 languages where there were a sufficient number of relevant studies. Incorporating non-English-language studies can expand the geographical coverage (i.e., the number of 2° × 2° grid cells with relevant studies) of English-language evidence by 12% to 25%, especially in biodiverse regions, and taxonomic coverage (i.e., the number of species covered by the relevant studies) by 5% to 32%, although they do tend to be based on less robust study designs. Our results show that synthesising non-English-language studies is key to overcoming the widespread lack of local, context-dependent evidence and facilitating evidence-based conservation globally. We urge wider disciplines to rigorously reassess the untapped potential of non-English-language science in informing decisions to address other global challenges.

Consistency Queries in Information Extraction

A new formal framework of learning - learning by consistency queries - is introduced and studied. The theoretical approach outlined here is implemented as the core technology of a prototypical development system named LExIKON which supports interactive information extraction in practically relevant cases exactly in the way described in the present paper
