Several projects aimed at identifying priority issues for conservation with high relevance to policy have recently been completed in several countries. Two major types of projects have been undertaken, aimed at identifying (i) policy-relevant questions most imperative to conservation and (ii) horizon scanning topics, defined as emerging issues that are expected to have substantial implications for biodiversity conservation and policy in the future. Here, we provide the first overview of the outcomes of biodiversity and conservation-oriented projects recently completed around the world using this framework. We also include the results of the first questions and horizon scanning project completed for a Mediterranean country. Overall, the outcomes of the different projects undertaken (at the global scale, in the UK, US, Canada, Switzerland and in Israel) were strongly correlated in terms of the proportion of questions and/or horizon scanning topics selected when comparing different topic areas. However, some major differences were found across regions. There was large variation among regions in the percentage of proactive (i.e. action and response oriented) versus descriptive (non-response oriented) priority questions and in the emphasis given to socio-political issues. Substantial differences were also found when comparing outcomes of priority questions versus horizon scanning projects undertaken for the same region. For example, issues related to climate change, human demography and marine ecosystems received higher priority as horizon scanning topics, while ecosystem services were more emphasized as current priority questions. We suggest that future initiatives aimed at identifying priority conservation questions and horizon scanning topics should allow simultaneous identification of both current and future priority issues, as presented here for the first time. We propose that further emphasis on social-political issues should be explicitly integrated into future related projects.

This paper examines changes in Israel's landscape by comparing two time periods, 1881 and 2011. For this purpose we compared land cover derived from the Palestine Exploration Fund historical map to a present land cover map that was compiled from 38 different present-day GIS layers. The research aims were (1) to quantitatively examine what were the changes in Israel's landscape between 1881 and 2011; (2) to identify and explain spatial patterns in these landscape changes. Landscape transformation was categorized into five classes: 'residual bare' (no change in natural vegetation, mostly in desert areas); 'residual' (i.e. remnant; no change in natural vegetation class); 'transformed' (changes between different natural vegetation areas); 'replaced' (area which became managed); 'removed' (no or minimal natural vegetation). We found that only 21% of the area retained similar landscape classes as in the past, with the largest changes taking place in ecoregions that were favorable for developing agriculture - Jezreel Valley and the Sharon Plain. Two physical factors had a strong effect on the type of change in the landscape: (1) most of the agricultural areas and human settlements were found in areas ranging between 400-600 mm/year (2) natural land cover features were more common in areas with steeper slopes. We found that the majority of protected areas, 54.6%, are comprised of remnant vegetation classes (i.e. residual transformation class) however more than half of protected areas are located in desert areas and are thus biased in their representation of land cover classes.
