  • Guiding biological control of alligator weed by Agasicles hygrophila (Coleoptera: Chrysomelidae) at macroscale: where are the potential global areas suitable to apply it and how it can change in climate change scenarios.

    Pulzatto, Mikaela Marques (Universidade Estadual de Maringá. Departamento de Biologia. Programa de Pós-Graduação em Ecologia de Ambientes Aquáticos Continentais., 2022)
    Invasive species can have many negative impacts on the biodiversity, ecosystem services, human health and the economy, and therefore need to be managed. An amphibious weed of global importance, Alternanthera philoxeroides, and the macroecological patterns of its biological control were evaluated using one of its main specialist herbivores, Agasicles hygrophila. This was considered the first successful case of biological control of an aquatic plant, although it is not equally effective on a global scale. Due to their different environmental tolerances and the greater phenotypic plasticity of the plant, the distribution of both species do not always overlap in the globe, creating geographic variability in the efficiency of biocontrol. The first approach was to analyze the current global potential distribution of A. philoxeroides and A. hygrophila to seek the areas of overlaps and gaps between them. The overlapping areas would be the most relevant for using A. hygrophila as alligator weed biological control in the globe. However, in response of climate change, it seems that the alligator weed is worryingly spreading across the globe, which can worsen in future scenarios and alter its distribution in the next decades. The second approach evaluated the effects of climate change on the global distribution of A. philoxeroides and A. hygrophila. New distribution areas for both species in future global warming scenarios and new overlapping and non-overlapping areas across the globe were identified. Species Distribution Models (SDMs) were applied in both chapters to predict the potential distribution of the two species in present and future scenarios considering different environmental predictors in each one. Currently, the southeast coast of the USA, southeast China and New South Wales, Australia are the most favorable areas in the world to apply alligator weed biocontrol, while the west coast and mid-latitudes in the east of the USA and the eastern Australia are not favorable. The results were corroborated by reports in the literature that demonstrated successful control in overlapping areas and failures in non-overlapping areas of the models’ distributions. However, while general geographic patterns will hold in future scenarios, it is predicted a major northward expansion of the alligator weed, but not of the insect, especially in the USA, Canada, Europe, China, South Korea and Japan, which will create a new zone of low or no control efficiency at higher latitudes. These macroecological patterns will help direct efforts to apply the biological control for the alligator weed not only today, but also in future climate change scenarios.
  • Pacific Islands Marine Bioinvasions Alert Network (PacMAN) monitoring plan.

    Suominen, Saara; Appeltans, Ward; Provoost, Pieter; Ginigini, Joape; Brodie, Gilianne; Kumar, Paayal; Intergovernmental Oceanographic Commission of UNESCO - Intergovernmental Oceanographic Data and Information Exchange (IODE) (UNESCO-IOC-IODE, 2021)
    Invasive species pose a major risk to marine biodiversity and ecosystem health (Bax et al. 2003, Molnar et al. 2008, Costello et al. 2010), and consequently to ecosystem services that are crucial for livelihoods and human well-being. The increasing movement of goods and services across the globe has enhanced the risk of invasive species throughout the world. Fiji is considered a hub of marine traffic among the Pacific Islands, and therefore is an entry point for high-risk invasive species in the area. Currently, the information on local marine biodiversity, and consequently marine invasive alien species (MIAS) is lacking in the Pacific Islands at large. While the Government of Fiji is active in biodiversity monitoring through the Biosecurity Authority of Fiji (BAF), the Fiji Invasive Alien Species Task Force (FIST), the National Invasive Species Framework and Action Plan (NISFSAP) currently under construction through Fiji’s national invasive species project and the Early Detection and Rapid Response (EDRR) program, many of these initiatives are focused on terrestrial biosecurity and lack a robust approach to address the problem at the marine ecosystem level. Consultation with local stakeholders revealed that increased efforts on marine biodiversity conservation should go hand in hand with increased efforts in MIAS management. National priorities for Fiji’s National Biodiversity Strategic Action Plan (NBSAP) addresses this link through its Focus Area 4: Management of Invasive Alien Species (IAS). Concerted efforts in this focus area are geared towards the establishment of an Invasive Species Database, the strengthening of the FIST, increased coordination between local and regional networks on IAS management and a renewed surge in national effort to raise the standard of biosecurity surveillance programs such as those found under the Early Detection and Rapid Response (EDRR) program for BAF. The successful development of these national programs, requires enhanced collection of information on marine biodiversity, knowledge on the existing presence of marine invasive species, and the development of routine monitoring to enable rapid responses to known highly invasive species. Existing frameworks at BAF utilized for terrestrial IAS management will be used to guide the development of future management plans for MIAS. BAF is the lead implementing agency for a GEF 6 project “Building Capacities to Address Invasive Alien Species to Enhance the Chances of Long-term Survival of Terrestrial Endemic and Threatened Species on Taveuni Island and Surrounding Islets” aimed at establishing and enhancing national and local capacity to prevent, detect, control and manage invasive alien species. A key planned outcome of the project is development of a clearinghouse mechanism to collate and make accessible IAS information to all stakeholders. The PaCMAN project will partner with the GEF6 IAS project in this regard so that MIAS data generated from the PacMAN project is curated, verified, uploaded and available through this clearing house. Through PacMAN outcomes, the Ministry of Environment has indicated to initiate a management policy on marine invasive species as a by-product of the management recommendations from the project. Technical capacity in molecular methods exists in pockets in Fiji, however further capacity development is necessary to ensure the effectiveness of eDNA in routine marine conservation efforts. BAF has been identified as a partner through local stakeholder consultations that will assist with technological gaps with its DNA analysis capacity through a recently acquired qPCR unit. Considering marine invasive species, Fiji is also one of the Lead Partnering Countries (LPCs) in the GEF/UNDP-IMO project “Building Partnerships to Assist Developing Countries Minimize the Impacts from Aquatic Biofouling (GloFouling Partnerships (https://www.glofouling.imo.org), indicating its willingness to establish a national strategic action plan to manage biofouling. The Secretariat of the Pacific Regional Environment Programme (SPREP) which is the regional coordinator for the Glofouling partnerships is committed to develop a MIAS toolkit as well as conduct capacity building training for local MIAS managers as well as key technical working groups such as the FIST. SPREP has expressed a need for data on marine biodiversity, as well as monitoring guidelines that will be developed through PacMAN. The interest and involvement of SPREP shows that there is a need for MIAS monitoring also in other regional countries in the Pacific. Further linkages can be observed from SPREP’s increased efforts in building capacity on IAS management in the region through its GEF 6 project and its Managing Invasive Species for Climate Change Adaptation in the Pacific (MISCCAP).

  • Ocean science roadmap for UNESCO Marine World Heritage in the context of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030).

    United Nations Educational, Scientific and Cultural Organization (UNESCO) (UNESCO, 2021)
    Climate change is altering our planet and the effects are felt from the highest mountains to the deepest parts of the ocean. While the world seeks to hold warming to 1.5°C, it is vital that we take steps now to protect some of the Earth’s natural jewels and to preserve them for future generations. The UNESCO World Heritage List includes the world’s most iconic marine protected areas, recognised by the international community for their outstanding biodiversity, beauty, geology and natural habitats. Beginning with Australia’s Great Barrier Reef in 1981, the List has since expanded to include a global network of 50 ocean places of Outstanding Universal Value (OUV), from the tropics to the poles, each of which helps to secure the future of our marine ecosystems. Inclusion on the List is only the start of the work needed to protect these sites from warming seas and shifting weather. Indeed, some 70% of the marine World Heritage sites are currently under threat from climate change, according to the 2020 IUCN World Heritage Outlook. Under a business-as-usual emissions scenario, World Heritage Listed coral reef systems are expected to cease to exist by 2100. Action is necessary not just to protect these sites, but because between them they host over 20% of the world’s blue carbon ecosystems - representing critical carbon sinks - and serve as refuges for vulnerable and threatened species. Managers, scientists, and funders are enthusiastic and willing to help us achieve healthy oceans and marine World Heritage sites. But how? The 2021 UNESCO science assessment survey of marine World Heritage sites indicates that nearly 75% of sites lack knowledge on how to protect their OUV against the impacts from climate change. And about two thirds lack the tools to understand how climate change will impact their biodiversity and ecosystem functioning.We must find evidence-based solutions to address these questions and to help sites plan for the uncertain future. In 2017, the United Nations General Assembly proclaimed that 2021-2030 would serve as the United Nations Decade of Ocean Science for Sustainable Development (or ‘Ocean Decade’). The Ocean Decade provides a global framework to harness science to sustainably manage the oceans. Marine World Heritage sites are identified as priority areas in the Implementation Plan of the Ocean Decade. The Decade offers a way to convene diverse actors to co-design and co-deliver knowledge that will address scientific questions about the vulnerable sites, to plan the right response and to put them on a path to a sustainable future. Climate change is a complex challenge, and we must use the best and most up-to-date research and data to guide our actions. Collecting ocean science data and identifying trends are critical to local management teams. Without this baseline knowledge, including where iconic species live or trends in environmental and socio-economic variables, effective management decisions cannot be made in ways that will ensure sites’ protection 10 or 20 years from now. Yet despite their iconic status, many marine World Heritage sites lack essential capacity, technology and resources to generate and process data, including the baseline observations crucial to gather the evidence to plan future steps. For many sites, budgets have not risen while challenges grow exponentially. In response, UNESCO is launching a call for increased and strategic investment in the ocean science needed to safeguard marine World Heritage sites. The ocean is a vast place and there is much to do. Within the framework of the Ocean Decade, this roadmap aims to help provide focus, to ensure research is carried out and used in an efficient, effective and sustainable way. It identifies knowledge that site managers and scientists need to conserve marine World Heritage sites and foster resilient marine ecosystems, highlights the value of science-based decision making, and tackles some key obstacles including resources and capacity. This roadmap outlines key information to assess climate vulnerability, including on the use of targeted science to underpin conservation and management efforts. It also highlights current gaps in science capacity and infrastructure, including data collection and interpretation. Finally, it explores the technology and capacity required for action and the sustainable finance and resources needed to support the necessary research. Marine World Heritage sites face a critical moment in time and we must act now. By developing this roadmap within the framework of the Ocean Decade, we have the chance to generate ‘the science we need for the ocean we want’ and preserve marine World Heritage sites and their services for future generations. This roadmap seeks to offer that help, by showing managers, supporters, and funders how science and research can be more cost-effectively directed to some of the most pressing problems. Together we can steer a path to a resilient and sustainable future, for the next decade and beyond.
  • Catalogue of hydrologic analysis for Asia and the Pacific, Volume 2: Dam reservoir operation for addressing water related disasters, water scarcity and quality.

    Kobayashi, Kenichiro; Yu, Zhongbo; Tabios III, Guillermo Q.; Dom, Norlida Mohd; Sutapa, Ignasius D.A.; Tachikawa, Yasuto; Thulstrup, Hans D.; UNESCO Office in Jakarta (UNESCO-Intergovernmenal Hydrological Programme (? International Hydrological Programme), 2021)
    It is our great pleasure to present the second volume of the Catalogue of Hydrologic Analysis for Asia and the Pacific. This volume focuses on the topic “Dam reservoir operation for addressing water related disasters, water scarcity and quality in Asia and the Pacific”. It contains seven documents from China, Indonesia, Japan, Republic of Korea, Malaysia, Philippines, and Viet Nam. It is the outcome of the international cooperation of the member countries of the Regional Steering Committee for Asia and the Pacific (RSC) under the auspices of the UNESCO Intergovernmental Hydrological Program Phase VIII (IHP-VIII, 2014-2021). It follows the 2020 publication of the Catalogue of Hydrologic Analysis (CHA) Volume 1. The objectives of the publication of the Catalogue of Hydrologic Analysis are: • To promote mutual understanding of hydrology and water resources of the region and of the neighboring countries. • To promote information exchange among different organizations in each country. • To share information on water-related issues such as disaster preparedness, water environment conservation, and water resources management in Asia and the Pacific. In Asia and the Pacific, various hydrologic analysis methods have been applied for designing hydraulic structures and river improvement works for rainfall-runoff predictions, flood inundation mapping and other purposes. These hydrologic analysis methods and experiences have different characteristics in terms of climate, topography, and development history of the catchments in which they are applied. Developing a platform to share these experiences and hydrologic analysis methods strengthen risk estimation and water-related hazard damage reduction; especially for researchers and engineers in the region who have limited knowledge of and experiences with them. To improve this situation and enhance risk estimation ability in research and engineering communities, meetings of the IHP Regional Steering Committee for Asia and the Pacific (RSC-AP) discussed the formation of a research team and the development of a hydro-informatics platform for Asia and the Pacific with the objective of realizing a hydro-hazard resilient region. With the objective enhancing regional capacity for evaluating water-related disaster risks, the RSC-AP decided to develop a Catalogue of Hydrologic Analysis (CHA) as a collaboration among researchers and engineers in Asia and the Pacific. The Catalogue collects documents including experiences and hydrologic analysis methods from practical use to advanced studies for short-term rainfall prediction, rainfall-runoff prediction, flood inundation mapping, hydrologic frequency analysis, eco-hydrology, and more. In this volume, we focus on dam reservoir operation in Asia and the Pacific. Since ancient times, dam reservoirs have aimed at securing water resources for living and agricultural production. Since then, industrial use and hydroelectric power generation were added – and most recently, securing the water environment and mitigating damage caused by floods. Dam operation methods are being studied and operated in each country to meet different objectives and to reduce the impact of flow control on the natural environment. This report summarizes the operation and water resource management of dams in China, Indonesia, Japan, Republic of Korea, Malaysia, Philippines, and Viet Nam. By developing and sharing knowledge through CHA, RSC-AP provides a platform to improve the ability for evaluating water-related disaster risks, which in turn will strengthen cooperation among researchers, governmental agencies and private sectors; serve to reduce the damage of water-related disasters; and stand as a regional contribution to achieve the targets of SDGs, UNESCO IHP-VIII (2014-2021) and UNESCO IHP-IX (2022-2029).
