Targeting degraded areas in forested landscapes for restoration could deliver rapid climate mitigation and biodiversity conservation, improve resilience of forested lands to future climate change, and potentially reduce the trade‐offs between nature recovery and agriculture. Although the importance of forest restoration for climate mitigation is acknowledged, current estimates of its climate mitigation potential may be underestimated because they focus predominantly on reforesting cleared areas. We built on recent analyses of forest integrity and unrealized forest biomass potential to examine the potential for restoring the integrity of degraded forests. There are over 1.5 billion ha of forests worldwide that retain 50–80% of their potential biomass. Prioritizing restoration in these areas could deliver rapid biodiversity and climate mitigation benefits, relative to restoring forest on cleared land. We applied a spatial planning approach to demonstrate how restoration interventions can be targeted to support the conservation of high‐integrity forest, a potential pathway to the delivery of the 30×30 goal of the Convention on Biodiversity's Global Biodiversity Framework.

Human activities such as urbanization, infrastructure and agriculture are driving global biodiversity declines. In an attempt to balance economic development goals with biodiversity conservation, governments and industry apply a decision‐making framework known as the mitigation hierarchy, with a goal of achieving no net loss or net gain outcomes for biodiversity. Successful application of the mitigation hierarchy requires biodiversity assessments and spatial planning to inform the design of mitigation policies, identify priority areas for biodiversity conservation and impact avoidance, assess the biodiversity impacts of developments, and identify appropriate mitigation measures including offsetting residual impacts. However, guidance on the necessary data and assessment techniques is often lacking, especially in countries where formal mitigation policies do not exist or are in their infancy. Here, we discuss and demonstrate analyses that can help answer some key questions for formulating effective mitigation policies and applying the mitigation hierarchy. We focus on data and analyses that can inform the avoidance and offset steps in particular, and demonstrate these techniques using a case study in Mozambique. While these analyses will not replace field‐based assessments for projects, they offer rapid, low‐cost approaches to support scoping and development of mitigation policy, planning and decision‐making, especially in relatively data‐poor regions.

- Abstract
58 pages, 5 figures, 3 tables, The World Economic Forum now ranks biodiversity loss as a top-five risk to the global economy, and the draft post-2020 Global Biodiversity Framework proposes an expansion of conservation areas to 30% of the earth’s surface by 2030 (hereafter the “30% target”), using protected areas (PAs) and other effective area-based conservation measures (OECMs). - Two immediate concerns are how much a 30% target might cost and whether it will cause economic losses to the agriculture, forestry and fisheries sectors. - Conservation areas also generate economic benefits (e.g. revenue from nature tourism and ecosystem services), making PAs/Nature an economic sector in their own right. - If some economic sectors benefit but others experience a loss, high-level policy makers need to know the net impact on the wider economy, as well as on individual sectors.

- Abstract
More ambitious conservation efforts are needed to stop the global degradation of ecosystems and the extinction of the species that comprise them. Here, we estimate the minimum amount of land needed to secure known important sites for biodiversity, Earth’s remaining wilderness, and the optimal locations for adequate representation of terrestrial species distributions and ecoregions. We discover that at least 64 million km 2 (43.6% of Earth’s terrestrial area) requires conservation attention either through site-scale interventions (e.g. protected areas) or landscape-scale responses (e.g. land-use policies). Spatially explicit land-use scenarios show that 1.2 million km 2 of land requiring conservation attention is projected to be lost to intensive human land-use by 2030 and therefore requires immediate protection. Nations, local communities and industry are urged to implement the actions necessary to safeguard the land areas critical for conserving biodiversity.

We assess the magnitude and the extent of recent change of significant human footprint within protected areas, key biodiversity areas and the habitat range of 308 lowland forest specialist birds in Sundaland, a global hotspot of biodiversity in Southeast Asia. Using the most recent human footprint dataset, we find that 70% of Sundaland has been heavily modified by humans. This represents a 55% increase in areas under intense human pressure since 1993. Areas under intense human pressure covered on average 50% of the extent of key biodiversity areas, 78% of each protected area and 38% of the range of lowland forest specialist birds. The results imply that the actual level of protection by protected areas is only one‐third to half of that on paper once human footprint is accounted for. While all protected areas were impacted by human pressures, those managed strictly for biodiversity conservation presented the largest increases. These results highlight an exceptionally high human footprint across Sundaland and an impending further deepening of the biodiversity crisis across the region. [ABSTRACT FROM AUTHOR]

Marine protected areas (MPAs) are a critical defense against biodiversity loss in the world's oceans, but to realize near‐term conservation benefits, they must be established where major threats to biodiversity occur and can be mitigated. We quantified the degree to which MPA establishment has targeted stoppable threats (i.e., threats that can be abated through effectively managed MPAs alone) by combining spatially explicit marine biodiversity threat data in 2008 and 2013 and information on the location and potential of MPAs to halt threats. We calculated an impact metric to determine whether countries are protecting proportionally more high‐ or low‐threat ecoregions and compared observed values with random protected‐area allocation. We found that protection covered <2% of ecoregions in national waters with high levels of abatable threat in 2013, which is ∼59% less protection in high‐threat areas than if MPAs had been placed randomly. Relatively low‐threat ecoregions had 6.3 times more strict protection (International Union for Conservation of Nature categories I–II) than high‐threat ecoregions. Thirty‐one ecoregions had high levels of stoppable threat but very low protection, which presents opportunities for MPAs to yield more significant near‐term conservation benefits. The extent of the global MPA estate has increased, but the establishment of MPAs where they can reduce threats that are driving biodiversity loss is now urgently needed. [ABSTRACT FROM AUTHOR]

HABITAT conservation , *ANTHROPOGENIC effects on nature , *ECOLOGICAL regions , *BIOMES , *CONSERVATION biology - Abstract
Anthropogenic conversion of natural habitats is the greatest threat to biodiversity and one of the primary reasons for establishing protected areas (PAs). Here, we show that PA establishment outpaced habitat conversion between 1993 and 2009 across all biomes and the majority ( n = 567, 71.4%) of ecoregions globally. However, high historic rates of conversion meant that 447 (56.2%) ecoregions still exhibit a high ratio of conversion to protection, and of these, 127 (15.9%) experienced further increases in this ratio between 1993 and 2009. We identify 41 'crisis ecoregions' in 45 countries where recent habitat conversion is severe and PA coverage remains extremely low. While the recent growth in PAs is a notable conservation achievement, international conventions and associated finance mechanisms should prioritize areas where habitat is being lost rapidly relative to protection, such as the crisis ecoregions identified here.

Fish biomass is a primary driver of coral reef ecosystem services and has high sensitivity to human disturbances, particularly fishing. Estimates of fish biomass, their spatial distribution, and recovery potential are important for evaluating reef status and crucial for setting management targets. Here we modeled fish biomass estimates across all reefs of the western Indian Ocean using key variables that predicted the empirical data collected from 337 sites. These variables were used to create biomass and recovery time maps to prioritize spatially explicit conservation actions. The resultant fish biomass map showed high variability ranging from ~15 to 2900 kg/ha, primarily driven by human populations, distance to markets, and fisheries management restrictions. Lastly, we assembled data based on the age of fisheries closures and showed that biomass takes ~ 25 years to recover to typical equilibrium values of ~1200 kg/ha. The recovery times to biomass levels for sustainable fishing yields, maximum diversity, and ecosystem stability or conservation targets once fishing is suspended was modeled to estimate temporal costs of restrictions. The mean time to recovery for the whole region to the conservation target was 8.1(± 3SD) years, while recovery to sustainable fishing thresholds was between 0.5 and 4 years, but with high spatial variation. Recovery prioritization scenario models included one where local governance prioritized recovery of degraded reefs and two that prioritized minimizing recovery time, where countries either operated independently or collaborated. The regional collaboration scenario selected remote areas for conservation with uneven national responsibilities and spatial coverage, which could undermine collaboration. There is the potential to achieve sustainable fisheries within a decade by promoting these pathways according to their social-ecological suitability. [ABSTRACT FROM AUTHOR]

To ensure the long-term persistence of biodiversity, conservation strategies must account for the entire range of climate change impacts. A variety of spatial prioritisation techniques have been developed to incorporate climate change. Here, we provide the first standardised review of these approaches. Using a systematic search, we analysed peer-reviewed spatial prioritisation publications (n = 46) and found that the most common approaches (n = 41, 89%) utilised forecasts of species distributions and aimed to either protect future species habitats (n = 24, 52%) or identify climate refugia to shelter species from climate change (n = 17, 37%). Other approaches (n = 17, 37%) used well-established conservation planning principles to combat climate change, aimed at broadly increasing either connectivity (n = 11, 24%) or the degree of heterogeneity of abiotic factors captured in the planning process (n = 8, 17%), with some approaches combining multiple goals. We also find a strong terrestrial focus (n = 35, 76%), and heavy geographical bias towards North America (n = 8, 17%) and Australia (n = 11, 24%). While there is an increasing trend of incorporating climate change into spatial prioritisation, we found that serious gaps in current methodologies still exist. Future research must focus on developing methodologies that allow planners to incorporate human responses to climate change and recognise that discrete climate impacts (e.g. extreme events), which are increasing in frequency and severity, must be addressed within the spatial prioritisation framework. By identifying obvious gaps and highlighting future research needs this review will help practitioners better plan for conservation action in the face of multiple threats including climate change.

CLIMATOLOGY , *CORAL reef ecology , *SEAGRASSES - Abstract
Decision making for the conservation and management of coral reef biodiversity requires an understanding of spatial variability and distribution of reef habitat types. Despite the existence of very high-resolution remote sensing technology for nearly two decades, comprehensive assessment of coral reef habitats at national to regional spatial scales and at very high spatial resolution is still scarce. Here, we develop benthic habitat maps at a sub-national scale by analyzing large multispectral QuickBird imagery dataset covering ~686 km² of the main shallow coral fringing reef along the southern border with Tanzania (4.68°S, 39.18°E) to the reef end at Malindi, Kenya (3.2°S, 40.1°E). Mapping was conducted with a user approach constrained by ground-truth data, with detailed transect lines from the shore to the fore reef. First, maps were used to evaluate the present management system's effectiveness at representing habitat diversity. Then, we developed three spatial prioritization scenarios based on differing objectives: (i) minimize lost fishing opportunity; (ii) redistribute fisheries away from currently overfished reefs; and (iii) minimize resource use conflicts. We further constrained the priority area in each prioritization selection scenario based on optionally protecting the least or the most climate exposed locations using a model of exposure to climate stress. We discovered that spatial priorities were very different based on the different objectives and on whether the aim was to protect the least or most climate-exposed habitats. Our analyses provide a spatially explicit foundation for large-scale conservation and management strategies that can account for ecosystem service benefits. [ABSTRACT FROM AUTHOR]

Global areal protection targets have driven a dramatic expansion of the marine protected area (MPA) estate. We analyzed how cost‐effective global MPA expansion has been since the inception of the first global target (set in 1982) in achieving ecoregional representation. By comparing spatial patterns of MPA expansion against optimal MPA estates using the same expansion rates, we show the current MPA estate is both expensive and ineffective. Although the number of ecoregions represented tripled and 12.7% of national waters was protected, 61% of ecoregions and 81% of countries are not 10% protected. Only 10.3% of the national waters of the world would be sufficient to protect 10% of each ecoregion if MPA growth since 1982 strategically targeted underrepresented ecoregions. Unfortunately 16.3% of national waters are required for the same representative target if systematic protection started in 2016 (an extra 3.6% on top of 12.7%). To avoid the high costs of adjusting increasingly biased MPA systems, future efforts should embrace target‐driven systematic conservation planning. [ABSTRACT FROM AUTHOR]

WILDERNESS areas , *BIODIVERSITY , *CORAL reefs & islands , *REMOTE sensing , *CONSERVATION biology - Abstract
Summary As human activities increasingly threaten biodiversity [ 1, 2 ], areas devoid of intense human impacts are vital refugia [ 3 ]. These wilderness areas contain high genetic diversity, unique functional traits, and endemic species [ 4–7 ]; maintain high levels of ecological and evolutionary connectivity [ 8–10 ]; and may be well placed to resist and recover from the impacts of climate change [ 11–13 ]. On land, rapid declines in wilderness [ 3 ] have led to urgent calls for its protection [ 3, 14 ]. In contrast, little is known about the extent and protection of marine wilderness [ 4, 5 ]. Here we systematically map marine wilderness globally by identifying areas that have both very little impact (lowest 10%) from 15 anthropogenic stressors and also a very low combined cumulative impact from these stressors. We discover that ∼13% of the ocean meets this definition of global wilderness, with most being located in the high seas. Recognizing that human influence differs across ocean regions, we repeat the analysis within each of the 16 ocean realms [ 15 ]. Realm-specific wilderness extent varies considerably, with >16 million km 2 (8.6%) in the Warm Indo-Pacific, down to <2,000 km 2 (0.5%) in Temperate Southern Africa. We also show that the marine protected area estate holds only 4.9% of global wilderness and 4.1% of realm-specific wilderness, very little of which is in biodiverse ecosystems such as coral reefs. Proactive retention of marine wilderness should now be incorporated into global strategies aimed at conserving biodiversity and ensuring that large-scale ecological and evolutionary processes continue.

DEFORESTATION , *BIODIVERSITY conservation - Abstract
The effect of armed conflict on deforestation in biodiverse regions across Earth remains poorly understood. Its association with factors like illegal crop cultivation can obscure its effect on deforestation patterns. We used Colombia, a global biodiversity hotspot with a complex political history, to explore the association of both armed conflict and coca cultivation with deforestation patterns. We generated spatial predictions of deforestation pressure based on the period 2000–2015 to understand how armed conflict and coca cultivation are associated with spatial patterns of deforestation and assess the spatial distribution of deforestation pressure induced by armed conflict and coca cultivation. Deforestation was positively associated with armed conflict intensity and proximity to illegal coca plantations. A deforestation model including 14 variables was 78% accurate in predicting deforestation at a 10 km2 resolution. On their own armed conflict and coca cultivation had a notable effect, particularly in the Amazon, but in combination with other variables it was small. Deforestation pressure induced by armed conflict and coca cultivation was highest in Tumaco and Catatumbo regions and in la Macarena, Sierra Nevada and San Lucas mountains—all areas of high biodiversity and conservation importance. In some regions, lack of governance after the peace accords is increasing armed conflict, and our results suggest that those increases in conflict may increase deforestation in those areas. The methods used here can be replicated to help understand the complex ways in which armed conflict affects deforestation patterns in other regions. [ABSTRACT FROM AUTHOR]

- Abstract
Remotely-sensed and bottom-up survey information were compiled on eight variables measuring the direct and indirect human pressures on the environment globally in 1993 and 2009. This represents not only the most current information of its type, but also the first temporally-consistent set of Human Footprint maps. Data on human pressures were acquired or developed for: 1) built environments, 2) population density, 3) electric infrastructure, 4) crop lands, 5) pasture lands, 6) roads, 7) railways, and 8) navigable waterways. Pressures were then overlaid to create the standardized Human Footprint maps for all non-Antarctic land areas. A validation analysis using scored pressures from 3114×1 km(2) random sample plots revealed strong agreement with the Human Footprint maps. We anticipate that the Human Footprint maps will find a range of uses as proxies for human disturbance of natural systems. The updated maps should provide an increased understanding of the human pressures that drive macro-ecological patterns, as well as for tracking environmental change and informing conservation science and application., Competing Interests: The authors declare no competing financial interests.
