Ecosystem services based adaptation to climate change: why and how?

Ecosystem services (ES) are the benefits community receive from ecosystems. The necessity of ES for community well-being and sustainable development is universally accepted. ES have already been negatively impacted by climate change and will only deteriorate further during this century, if adequate adaptation measures are not taken. Noting ES are a relatively new dimension in the context of climate change, globally scientists and policy makers are busy searching for suitable adaptation options and ensuring an uninterrupted flow of ES. In this study, we have used climate change models, and synthesized the scholarly findings to answer two research questions (i) Why are ES based adaptations required? and (ii) What types of suitable adaptation options are available to ensure an uninterrupted supply (and flow) of ES? The study has been conducted in the Wet Tropics, Australia considering its outstanding national and global ecological significance. Our study has revealed that apart from the temporal and spatial variation, the magnitude of climate change impacts will be different for each ES. Therefore ES-based adaptations will ensure a sustainable supply and flow of ES, generating multiple ecological and community co-benefits. We have found a number of available adaptation options for different ES with substantial scientific evidence in the scholarly findings which can be implemented quite readily in the face of climate change. Some of these are: climate regulation- natural forests protection, agroforestry, planting higher wood density trees; water provision and regulation- upland forests protection, riparian restoration; coastal protection and erosion control- mangrove protection and landward facilitation, restoration of littoral forests, coastal plantation, green engineering; habitat provision-ecological connectivity, agroforestry; timber provision-planting tropical cyclone resistant trees. This study shall be useful for decision makers to incorporate suitable ES based adaptation options into their climate change related decisions, and for practitioners to select suitable adaptation options for interested ES

Where are the hot spots of ecosystem services?

Ecosystem services (ES) are the bridge between nature and society, and are essential elements of any community's wellbeing. Australia is a place of diverse climates with a narrow band of wet tropics in Far North Queensland. The Wet Tropics is environmentally diverse, iconic in biodiversity, and supplies numerous ES influencing community wellbeing of this region, Australian national economy, and global climate change mitigation efforts. However ES in the Wet Tropics have rarely been assessed. We dealt with two questions: i) how are ES spatially distributed across the Wet Tropics, ii) where are the hot spots of ES production. We have classified the Wet Tropics forests into four types: coastal eucalypt forests and wood lands, coastal rainforests, eucalypts hills and ranges, and wet highland rainforests. Vegetation data metrics have been collected from 70 plots of 0.05 ha each located from coast to more than 1000m above msl. We have spatially assessed the ES in these forest types. We have found spatial congruence and differences of ES production across the forest types. Different forests types have produced different ES in higher quantity. Our study has revealed that hot spots of ES production are widely distributed across the different forests types in the Wet Tropics. Disturbance regimes (cyclones, forest fire) and conservation priority in management options have also influenced the usual spatial trend of ES production. This study shall be useful for decision makers to incorporate ES into their natural resource management planning, and for practitioners to evaluate areas identified with ES significance

Climate change impacts and adaptation pathways on key regional ecosystem services in the Wet Tropics NRM Cluster Region, Australia

Climate change alters the functions of ecosystems and as a result, the provision of ecosystem services and wellbeing of people that rely on these services. The concept of ecosystem services is aimed at supporting this broad and open dialogue in ways that allow potential synergies and tradeoffs among social, economic and ecological objectives to be identified and addressed with due reference to the multiple perceptions that people have about benefits and beneficiaries from the environment. In this paper we discuss insights about the impacts of climate change on key regional ecosystem services for the Wet Tropics. Syntheses of published ideas and approaches are presented with key climate change messages for NRM groups to enable them to incorporate into their new regional plans for the Wet Tropics Cluster Region

Is investment in Indigenous land and sea management going to the right places to provide multiple co-benefits?

Indigenous land and sea management (ILSM) has been the focus of large government investment in Australia and globally. Beyond environmental benefits, such investments can deliver a suite of social, cultural and economic co-benefits, aligning with the objectives of Indigenous communities and of governments for culturally appropriate socio-economic development. Nevertheless, there have been very few studies done on the spatial distribution of this investment and the extent to which its associated co-benefits address socio-economic disadvantage, which is unevenly distributed across Australia. This study draws on Australian ILSM programmes to examine the spatial and temporal distribution of investment for ILSM between 2002–2012 and considers implications for the distribution of associated co-benefits. Mapping and analysis of 2600 conservation projects revealed that at least $462M of investment in ILSM projects had occurred at 750 discrete sites throughout Australia. More than half of this investment in ILSM has been concentrated in northern Australia, in disadvantaged remote and very remote areas where a high percentage of the population is Indigenous, and Indigenous land ownership extensive. Our research has shown that ILSM investment has successfully been spatially distributed to areas with high needs for multiple social, economic, environmental and health and well-being co-benefit outcomes

Optimization of double pulse pumping for Ni-like Sm x-ray lasers

We report a systematic study of double pulse pumping of the Ni-like Sm x-ray laser at 73 Angstrom, currently the shortest wavelength saturated x-ray laser. It is found that the Sm x-ray laser output can change by orders of magnitude when the intensity ratio of the pumping pulses and their relative delay are varied. Optimum pumping conditions are found and interpreted in terms of a simple model. (C) 1999 American Institute of Physics. [S0021-8979(99)07102-9]

The Social and Economic Long Term Monitoring Program (SELTMP) 2014: Recreation in the Great Barrier Reef

[Extract] Introduction.\ud People love to spend their recreational time visiting the Great Barrier Reef World Heritage Area (GBRWHA), (GBRMPA, 2009), and many people are doing it! The recent SELTMP surveys revealed that 95% of residents of coastal town adjacent to the GBR had visited the GBRWHA for recreation at least once, and 87% had visited in the previous 12 months. Many of these visits appeared to be to a mainland beach to walk, swim, and relax. However, 68% of people who told us about their recent trips had been beyond the mainland beach to islands, reefs, shoals, etc., to take part in activities such as fishing, snorkelling and diving. Other activities include boating, sailing, jet skiing, camping, kayaking, sight-seeing, photography, and wildlife viewing, to name a few. Recreational visitors are currently very satisfied with their use of the Marine Park.\ud \ud While most trips beyond the beach were made by ferry, about a third of these trips were accessed by residents' own or someone else's boat. While not everyone is using their vessel very frequently, vessel registration by coastal residents has increased substantially in recent years (Old Department of Transport, unpublished data, 2011).\ud \ud Given all of this activity, it is not surprising that recreation in the GBRWHA provides significant social and cultural benefits as well as many health and wellbeing benefits associated with the psychological interaction with nature (Synergies Economic Consulting, 2012). In economic terms, recreation (defined by Deloitte Access Economics as GBR catchment residents visiting an island, sailing, boating and fishing), contributed $126m in direct value or$243.9m value added to the Australian economy in 2011/12 (Deloitte Access Economics, 2013). This estimate did not include beach visits.\ud Importantly, recreation differs from tourism. The Great Barrier Reef Marine Park Authority define recreation as an independent visit for enjoyment that is not part of a commercial operation (GBRMPA, 2012). For the purposes of the SELTMP Surveys (outline following), any resident of the GBR catchment who visits the GBRWHA is included within recreation; while tourists are defined as those residing outside of the GBR catchment

Enhanced inverse bremsstrahlung heating rates in a strong laser field

Test particle studies of electron scattering on ions, in an oscillatory electromagnetic field have shown that standard theoretical assumptions of small angle collisions and phase independent orbits are incorrect for electron trajectories with drift velocities smaller than quiver velocity amplitude. This leads to significant enhancement of the electron energy gain and the inverse bremsstrahlung heating rate in strong laser fields. Nonlinear processes such as Coulomb focusing and correlated collisions of electrons being brought back to the same ion by the oscillatory field are responsible for large angle, head-on scattering processes. The statistical importance of these trajectories has been examined for mono-energetic beam-like, Maxwellian and highly anisotropic electron distribution functions. A new scaling of the inverse bremsstrahlung heating rate with drift velocity and laser intensity is discussed.Comment: 12 pages, 12 figure
