  • Invasive Species are Changing the Nature of the Mediterranean Sea

    • Sep 5, 2022
    • UN. Food and Agriculture Organization.

    • The Mediterranean Sea is being invaded by hundreds of fish, jellyfish, prawns and other marine species from outside the region. More than 1 000 non-indigenous species have been identified in the Mediterranean and the Black Sea. Over half have established permanent populations and are spreading, causing concern about the threat they pose to marine ecosystems and local fishing communities.

      “Climate change and human activities have had a profound impact on the Mediterranean and the Black Sea,” says Stefano Lelli, a fishery expert for the eastern Mediterranean working for the General Fisheries Commission for the Mediterranean (GFCM). This regional fisheries management body, established by FAO, is leading efforts to promote sustainable fisheries and aquaculture in the Mediterranean and the Black Sea.

  • Asian Citrus Greening Disease: The Threat to Africa’s Citrus Trade

    • CAB International. Invasives Blog.

    • The yield losses attributed to Asian citrus greening disease once established can be devastating. If the disease continues to spread unabated in the citrus growing regions of East Africa, the annual value of lost production could potentially reach up to US $127 million over the next ten to 15 years, according to a recent paper published by CABI. The paper, The Asian Citrus Greening Disease (Huanglongbing): Evidence Note on Invasiveness and Potential Economic Impacts for East Africa (Jun 2021) [PDF, 2.9 MB], provides a review of the global literature on Asian citrus disease or huanglongbing (HLB) and estimates its potential economic impact on East Africa. The paper also makes recommendations for biosecurity preparedness, surveillance and management options to help decision-makers and citrus growers.

  • Invasive Alien Species Cost Africa's Agricultural Sector an Estimated USD $3.6 Trillion a Year

    • May 20, 2021
    • CAB International.

    • CABI scientists have conducted the first comprehensive study on the economic impact of a range of Invasive Alien Species (IAS) on Africa's agricultural sector, which they estimated to be USD $3.6 trillion a year. This is equivalent to 1.5 times the Gross Domestic Product (GDP) of all African countries combined – or similar to that of Germany. The average annual cost of IAS per country was USD $76.32 billion. Full details of the cost for individual countries are outlined in the paper published in the journal CABI Agriculture and Bioscience.

  • New Book is Treasure Trove of Information on Invasive Species

    • Apr 2020
    • Stellenbosch University (South Africa).

    • Published recently as an open access encyclopaedic book, Biological Invasions in South Africa provides the reader with information on 1422 alien species including, among others, plants, birds, mammals, fish, terrestrial invertebrates, invasive marine organisms and disease-causing microorganisms that have naturalised or become invasive in the country. Comprising 31 chapters, it covers themes such as the history of research in South Africa, detailed accounts of major groups of plants and animals, policy development, the development of a robust ecological theory about biological invasions, the effectiveness of management interventions and scenarios for the future regarding biological invasions in the country.
