      18th World Lake Conference One Year to Go Pre-conference Virtual Event

          In view of the ongoing COVID-19 pandemic and the desire of the 18th World Lake Conference (WLC18) Organizing Committee to ensure the health and safety of conference attendees, the Committee made the difficult decision to postpone the Conference, originally scheduled to be held in Guanajuato, Mexico during 9-14 November, 2020 to a new date in November, 2021.

          As a means of providing our WLC18 audience with an alternative event between the original and re-scheduled WLC18 dates, the Organizing Committee is hosting a pre-conference virtual event to be held during 9 November, 2020, with a focus on natural and manmade lake sustainability challenges and solutions. It will consist of two separate complementary sessions, each being two-and-a-half hours in duration. To accommodate participants in different time zones, one session will take place in the morning between 10:00 – 12:30 hrs and the second in the evening between 19:00 – 21:30 hrs (Mexico Central Time).

         Each session will comprise a keynote address, followed by a moderator-led panel discussion on the keynote and related topics. Virtual event participants also can submit relevant questions to the panelists and keynote speakers.

         The keynote speaker of the morning session is Professor Sandra Azevedo, Federal University of Rio de Janeiro, Brazil, who is also ILEC Scientific Committee Member. And Professor Shinjiro Sato, Soka University, Japan is the keynote speaker of the evening session. The panelists include individuals from a range of government agencies, academia, international organizations and NGOs. Prof. Walter Rast, Mr. Alejandro Juarez and Prof. Masahisa Nakamura from ILEC, will also participate as the panelists.

         All interested in lake science and management challenges are invited to participate in either or both sessions if they wish.

         Details and updates on both WLC18 and the virtual event program, keynote speakers and panelists, are available on the following WLC18 websites.

      International Webinar by UNEP and ILEC – This Event has Ended.


      An International Webinar by UNEP and ILEC entitled, “Mainstreaming Lakes in the Global Water Agenda” will be organized on Tuesday, October 27th, 2020, 5:00 pm - 8:00 pm Japan Time (UTC +9).

      ILEC, with the support of UNEP, has prepared a draft Statement entitled, “The Need to Mainstream Lakes and Other Lentic Waters within the Global Water Agenda”.  As a follow up, this forthcoming International Webinar addresses this subject, with participation by selected countries in Asia and Africa, providing an overview of their lake basin management national policies and programs as well as the experience and lessons learned so far in their implementation. The presentations will also include their adoption of the Integrated Lake Basin Management (ILBM) framework within their national water resources and river basin management plans as represented by such frameworks as Integrated Water Resources Management (IWRM) and Integrated River Basin Management (IRBM). 

      Some of the ILEC Scientific Committee members will take part in this webinar as speakers. We will be waiting for your participation.

    • Reschedule of WLC18 due to COVID-19 Outbreak

      After careful consideration and prioritizing the health and safety of attendees in view of the ongoing COVID-19 pandemic, the 18th World Lake Conference Organizing Committee has made the difficult decision to postpone the Conference originally scheduled to be held in the City of Guanajuato, Mexico, during November 9th to 14th, 2020. The anticipated new conference date will be November, 2021, with the specific date to be confirmed. Further, a virtual conference event is being anticipated for November 9th, 2020 (Central Mexico time), with details to be provided at a later date.

      The Organizing Committee also wishes to let current conference participants know the abstracts already sent will be honored. Further, in view of the conference postponement, the Organizing Committee will continue to accept abstracts and requests for Special Sessions and workshops through May 31, 2021.

      We appreciate your kind understanding and support as we navigate the current difficult situation confronting us on a global scale. In the meantime, the threats facing lakes, reservoirs and wetlands continue to increase round the world, seriously affecting their sustainable use, as well as their wide range of ecosystem services crucial for human health and economic livelihoods. In fact, this postponement can be viewed as an indispensable opportunity for us to pursue the emergent scientific and management challenges awaiting us in this new era.
      Accordingly, please continue to monitor the WLC18 official website
      or ILEC website
      for updates and upcoming dates.

    • Mainstreaming Lakes in the Global Water Agenda(Updated on Oct. 6. 2020 )

      In association with the 17th World Lake Conference held in Ibaraki, Japan, ILEC convened an International Colloquium on October 14, 2018 to discuss the role and importance of lakes and reservoirs in the international water arena. The Colloquium comprised participants from governments, UN agencies and international organizations from around the world.<Related Article>

      The following Statement is the draft output arising from discussions at the Colloquium as appropriately revised to increase appreciation and understanding of the important role of these waterbodies in the global water agenda, based on input from the ILEC Scientific Committee and the related participating organizations. PDF

      Upon reviewing the draft Statement, readers are cordially invited to provide active comments and feedback on the contents and its intended goals, which will increase its value to those responsible for assessing and managing these important waterbodies for their sustainable use.
