Engaging stakeholders in using future scenarios to analyse the potential impacts of agricultural development in the Lake Victoria Basin
This report presents the proceedings from the inception workshop for the project âEngaging stakeholders in using future scenarios to analyse the potential impacts of agricultural development in the Lake Victoria Basinâ. This two-year project (2015-2017) aims to ensure that land-use related decision-making in the Lake Victoria Basin (LVB) takes into consideration biodiversity and ecosystem services and is based on sound information and on the consideration of trade-offs between food production and conservation goals. The long-term outcome of the project will be a reduction in the adverse impacts of agricultural commodity developments on biodiversity, ecosystem services and human well-being in the LVB
Developing ecosystem service indicators: experiences and lessons learned from sub-global assessments and other initiatives
People depend upon ecosystems to supply a range of services necessary for their survival and well-being. Ecosystem service indicators are critical for knowing whether or not these essential services are being maintained and used in a sustainable manner, thus enabling policy makers to identify the policies and other interventions needed to better manage them. As a result, ecosystem service indicators are of increasing interest and importance to governmental and inter-governmental processes, including amongst others the Convention on Biological Diversity (CBD) and the Aichi Targets contained within its strategic plan for 2011-2020, as well as the emerging Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). Despite this growing demand, assessing ecosystem service status and trends and developing robust indicators is o!en hindered by a lack of information and data, resulting in few available indicators. In response, the United Nations Environment Programme World Conservation Monitoring Centre (UNEP-WCMC), together with a wide range of international partners and supported by the Swedish International Biodiversity Programme (SwedBio)*, undertook a project to take stock of the key lessons that have been learnt in developing and using ecosystem service indicators in a range of assessment contexts. The project examined the methodologies, metrics and data sources employed in delivering ecosystem service indicators, so as to inform future indicator development. This report presents the principal results of this project
Benthic habitat modelling and mapping as a conservation tool for marine protected areas: A seamount in the western Mediterranean
1. An ecologically representative, wellâconnected, and effectively managed system of
marine protected areas (MPAs) has positive ecological and environmental effects
as well as social and economic benefits. Although progress in expanding the coverage of MPAs has been made, the application of management tools has not yet
been implemented in most of these areas.
2. In this work, distribution models were applied to nine benthic habitats on a Mediterranean seamount within an MPA for conservation purposes. Benthic habitat
occurrences were identified from 55 remotely operated vehicle (ROV) transects,
at depths from 76 to 700 m, and data derived from multibeam bathymetry. Generalized additive models (GAMs) were applied to link the presence of each benthic
habitat to local environmental proxies (depth, slope, backscatter, aspect, and
bathymetric position index, BPI).
3. The main environmental drivers of habitat distribution were depth, slope, and BPI.
Based on this result, five different geomorphological areas were distinguished. A
full coverage map indicating the potential benthic habitat distribution on the seamount was obtained to inform spatial management.
4. The distribution of those habitats identified as vulnerable marine ecosystems (VMEs)
was used to make recommendations on zonation for developing the management
plan of the MPA. This process reveals itself as an appropriate methodological
approach that can be developed in other areas of the Natura 2000 marine networkEn prensa1,92
Securing tropical forest carbon: the contribution of protected areas to REDD
Forest loss and degradation in the tropics contribute 6-17% of all greenhouse gas emissions. Protected areas cover 217.2 million ha (19.6%) of the world's humid tropical forests and contain c. 70.3 petagrams of carbon (Pg C) in biomass and soil to 1 m depth. Between 2000 and 2005, we estimate that 1.75 million ha of forest were lost from protected areas in humid tropical forests, causing the emission of 0.25-0.33 Pg C. Protected areas lost about half as much carbon as the same area of unprotected forest. We estimate that the reduction of these carbon emissions from ongoing deforestation in protected sites in humid tropical forests could be valued at USD 6,200-7,400 million depending on the land use after clearance. This is >1.5 times the estimated spending on protected area management in these regions. Improving management of protected areas to retain forest cover better may be an important, although certainly not sufficient, component of an overall strategy for reducing emissions from deforestation and forest degradation (REDD
Assessing the cost of global biodiversity and conservation knowledge
Knowledge products comprise assessments of authoritative information supported by stan-dards, governance, quality control, data, tools, and capacity building mechanisms. Considerable resources are dedicated to developing and maintaining knowledge productsfor biodiversity conservation, and they are widely used to inform policy and advise decisionmakers and practitioners. However, the financial cost of delivering this information is largelyundocumented. We evaluated the costs and funding sources for developing and maintain-ing four global biodiversity and conservation knowledge products: The IUCN Red List ofThreatened Species, the IUCN Red List of Ecosystems, Protected Planet, and the WorldDatabase of Key Biodiversity Areas. These are secondary data sets, built on primary datacollected by extensive networks of expert contributors worldwide. We estimate that US116â204 million), plus 293 person-years of volunteer time (range: 278â308 person-years) valued at US12â16 million), were invested inthese four knowledge products between 1979 and 2013. More than half of this financingwas provided through philanthropy, and nearly three-quarters was spent on personnelcosts. The estimated annual cost of maintaining data and platforms for three of these knowl-edge products (excluding the IUCN Red List of Ecosystems for which annual costs were notpossible to estimate for 2013) is US6.2â6.7 million). We esti-mated that an additional US12 million. These costs are much lower than those tomaintain many other, similarly important, global knowledge products. Ensuring that biodi-versity and conservation knowledge products are sufficiently up to date, comprehensiveand accurate is fundamental to inform decision-making for biodiversity conservation andsustainable development. Thus, the development and implementation of plans for sustain-able long-term financing for them is critical
Attaining Aichi Target 11: How Well Are Marine Ecosystem Services Covered by Protected Areas?
The spatial coverage of marine and coastal protected areas worldwide has shown a rapid increase in recent years. Over 32% of the world's coral reefs and over 36% of the world's mangrove forests now fall within protected areas. However, simple measures of extent are insufficient for assessing progress toward achieving global targets. Notably, the CBD Aichi Target 11 calls for 'at least 17 per cent of terrestrial and inland water areas, and 10 per cent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services' to be protected. There is, therefore, an urgent need to assess how well protected areas cover these areas of importance for ecosystem services
Strengthening Synergies: How Action to Achieve Post-2020 Global Biodiversity Conservation Targets Can Contribute to Mitigating Climate Change
The essential contribution of nature to addressing climate change provides an opportunity to strengthen the links between the United Nations Framework Convention on Climate Change and the Convention on Biological Diversity. As we move towards the next Conferences of the Parties of both Conventions, there is a need to assess explicitly the role of nature in helping to meet the goals of these agreements efficiently and effectively. This series of reports aims to shed light on this topic by assessing the potential contribution that achieving biodiversity conservation targets can make to climate change mitigation. By doing so, it aims to provide both context and mandate for discussions under both Conventions on the role of nature-based solutions in climate change mitigation and links to biodiversity conservation action
