News

15th April 2014 - the Mangrove Lab were busy presenting their research today in NUS at the Graduate Research Workshop. Val was talking about mangrove and seagrass carbon stocks, Pierre enthralled everyone with his project on mangrove carbon fluxes, and Wei Kit explored themes related to the coastal protection value of mangroves in Singapore. And now everyone else in the room wants to be a mangrove researcher!

18th March 2014 - Val, Sonia, Dan and other members of NUS Geography have been taking subtidal soil cores off the coast of East Singapore. To do this we had to use a gravity corer off the side of a boat! This is part of Val's Masters project on the carbon stocks of the different intertidal habitats of Singapore. As well as the subtidal mudflats, Val has also been calculating the carbon stock stored in mangroves and seagrass.

2nd March 2014 - Come join the Mangrove Lab at the Society for Conservation Biology's Asia Chapter meeting from 19th-22nd August in Melaka, Malaysia. We are chairing a symposium on "Ecosystem Services of Threatened Mangroves in Southeast Asia". If you'd like to present send us an email! More info at www.scbasia2014.org.

28th Feb 2014 - Dan was at James Cook University for the Australian Mangrove Society conference. This meeting brought together academics, researchers, government, NGOs and citizen scientists to discuss the state of Australia's coastal zone, and share new research on mangroves. Dan presented our current project on propagule dispersal modelling.

21st Feb 2014 - Rachel and Dan were in Bogor, Indonesia, for a workshop on "Restoring Coastal Livelihoods". The workshop was hosted by Mangrove Action Project and CIFOR, and brought together academics, government, NGOs and other stakeholders to discuss mangrove management and restoration. Rachel presented her Masters research on restoration in Sulawesi, and Dan gave a few presentations on how to monitor mangrove vulnerability to sea level rise, and how to use Google Earth to monitor mangrove encroachment.

17th Jan 2014 - Dan and Grahame Oliver have just written the book "Dynamic Environments of Singapore", published by McGraw Hill. Over 15 chapters, this book covers Singapore's numerous coastal, terrestrial and aquatic environments, and the geological and biophysical processes that shape them. We also ask "what will Singapore's environment look like in the future?" Read a review of this book here!

12th Jan 2014 - The Mangrove Lab has just returned from fieldwork in Southern Thailand. We were remeasuring Rod Surface Elevation Tables (RSETs): these instruments are drilled into the bedrock and measure surface elevation change in the mangrove, as a response to sea level rise. We also conducted the maiden flight of our new UAV to collect aerial imagery of the mangrove!

22nd Dec 2013 - we're finishing up the year with a few publications that are now available online. If you're interested in variability in mangrove change estimates (Global Ecology and Biogeography), mangrove deforestation in the Ayerwaddy Delta (Global Environmental Change) or rapid creek erosion due to wetland restoration (Geomorphology) then download them from the Publications page!

12th Dec 2013 - Valerie and Dan were in Jakarta for the 1st International Workshop on Blue Carbon Indonesia. This workshop was hosted by the Department of Fisheries and Marine Affairs, Blue Carbon Indonesia, GIZ and Conservation International. The goal is to create and implement a National Science Plan for Blue Carbon.

27th Nov 2013 - The environmental news service Mongabay covered our recent paper "Deforestation in the Ayeyarwady Delta and the conservation implications of an internationally-engaged Myanmar", recently published in Global Environmental Change. It reports a study where we documented mangrove loss in the context of recent and future reforms in Myanmar. See the story here and the paper here

20th Oct 2013 - Dan was in London for the kick off meeting for the newly formed IUCN Mangrove Specialist Group, hosted by the Zoological Society of London. This is an exciting new group of mangrove experts from around the world bridging the gaps between academia and conservation, and representing mangroves in international policy.

26th Sept 2013 - Dan is giving a public talk at the Science Centre Cafe next week, entitled: "Biophysical Threats to the Mangrove Swamps of Southeast Asia". Dan will talk about the biophysical processes that threaten mangroves, and how we need to understand these processes in order to manage them.


When: 1st October, 7pm

Where: The Science Centre, Singapore (entry fee applies)

25th Sept 2013 - Rachel has spent the last 3 weeks in Sulawesi, working on the preparation for a large mangrove restoration project due to take place in November. Together with colleagues from Mangrove Action Project and student volunteers from Universiti Hassanudin, Rachel mapped the elevation of abandoned shrimp ponds and natural mangrove forests. This information can be used to predict restoration success. Rachel will be flying back there soon!

31st Aug 2013 - along with Sivasothi in Biology, we held the Mandai Mangrove and Mudflat Workshop. We had over 150 attendees and 30 presentations covering plants, pollination, seagrass, (lots of) crabs, birds, wave attenuation, sedimentation, surface elevation change, pollution, management and law! Several members of the Mangrove Lab presented their student thesis work. The aim of this workshop was to bring all of this research together, and think about the future management of Mandai. For a workshop summary click here!

23rd Aug 2013 - we've uploaded some remote sensing guides, covering the use of Google Earth and other free shareware for higher-level GIS analyses, geocorrection and land cover classification in ERDAS Imagine. We'll be adding more guides as we get them! Feel free to download, use and distribute! See the Publications page for more info.

23rd Aug 2013 - Dan was in Bali, helping conduct training for the USAID Workshop on Response of Mangrove Wetland to Sea Level Rise, organized by Frida Sidik, Cath Lovelock (University of Queensland) and Candy Feller (Smithsonian). 20 young Indonesian researchers conducted projects about forest structure, carbon stock assessment, invertebrate communities, mangrove restoration and remote sensing. A fascinating workshop with some great data presented!

4th Aug 2013 - WORKSHOP ANNOUNCEMENT

On the 31st of August Sivasothi and Dan are hosting a workshop on the last 50 years of research conducted at Mandai - a mangrove under threat in Singapore. Everything from biology, zoology, ecology, geography and management! Find out more and sign up here!

28th June 2013 - Dan spent a week in West Thailand along with Dr. Ziegler (see his lab here), Dr. Carl Grundy-Warr and ~40 students on the Geog Department's annual 6 week Field Studies course. We were looking at a range of coastal issues, such as tsunami escape routes and tsunami boulders in Khao Lak, and mangrove restoration and carbon/biomass measurements in Ranong!

15th May 2013 - Rachel and Dan were in Makassar, Sulawesi, Indonesia, checking out research field sites with the Mangrove Action Project - a great NGO promoting community-led natural mangrove regeneration. Along with staff and students from Universiti Hasanuddin, we will be creating digital elevation models of abandoned shrimp ponds and measuring the flooding tolerances of different mangrove species. Rachel will be using this information to predict where mangrove restoration will be most successful or where other measures are required. Makassar also fulfils another important research site criteria - it has great food!

3rd May 2013 - Valerie and Dan were in SW Thailand for a US Forest Service workshop on quantifying mangrove carbon. We worked with friends and colleagues from all over SE Asia, Papua New Guinea and the US, measuring trees and taking soil cores. Hopefully we'll see a lot more mangrove carbon stock assessments in our region over the coming months!

25th Apr 2013 - NEW PAPER IN NATURE CLIMATE CHANGE


"A global standard for monitoring coastal wetland vulnerability to accelerated sea level rise"


Wetland elevation is an often ignored piece of the jigsaw puzzle when it comes to monitoring coastal dynamics and sea level rise. We make the case for low-cost, effective regional monitoring networks using the Surface Elevation Table to monitor threatened wetland ecosystems and their response to rising sea levels. To access this paper drop me an email or click here!

3rd Mar 2013 - we just returned from Rajamangala University, Trang Province, Thailand, where Dan was running a graduate field methods module for Singaporean and Thai students. Tasks included mapping areas of mangrove colonization, studying coastal morphodynamics, hunting for buried tsunami deposits (left), learning about flooding events, and igneous geology! See the Photos page!

25th Jan 2013 - the Queen, Prince of Orange and Princess Maxima of The Netherlands, Ambassador Tommy Koh and a number of Singaporean and Dutch ministers visited the NUS Aquatic Science Centre today. Dan talked about mangroves, and particularly our research in Singapore and Thailand and its importance for understanding mangrove conservation and restoration in the region.

Dec 8th 2012 - we've just returned from the 1st ASEAN Congress on Mangrove Research, organized by the Philippines Govt. Department of Environment and Natural Resources. This workshop drew together top scientists, practitioners and policymakers from across the region. Dan presented on establishing a Philippines and ASEAN network for Sea Level Rise vulnerability monitoring. Watch this space!


Nov 29th 2012 - Rickson, Rachel and Dan spent a week battling monkeys and the monsoon weather to take the first Surface Elevation Table measurements in SW Thailand, which we first installed in July-August. We'll be heading back there every 6 months for the next 5-10 years to see if the mangroves here are accreting or sinking, and whether the surrounding villages will be vulnerable to sea level rise.

Oct 14th 2012 - Dan will be speaking at a workshop on Weds 24th Oct - "Biological Approaches to Coastal Enhancement and Restoration" organised by NParks, Deltares and NUS. Dan will be talking about coastal research relevant to mangrove restoration, with experience from NGOs in the region. Register with Sally Teh sally@nus.edu.sg. Click here

Sept 14th 2012 - we just returned from Sheffield, UK for a workshop "Decentering Knowledge Production". We talked about biases in the global spread of mangrove research, which is currently centred in a handful of countries such as the US and Australia, and the implications of this for the management of mangroves in under-researched regions such as SE Asia and the Pacific islands.

Aug 15th 2012 - the Mangrove Lab just returned from 3 weeks of fieldwork in Trang Province, SW Thailand. We installed 24 Surface Elevation Tables to measure long-term changes in mangrove surface elevation. This information helps us estimate whether these mangroves are vulnerable to sea level rise. Sounds simple, but it means drilling solid steel rods into the bedrock - and that needs power tools! Click on the Photo Gallery page to see more!

Jul 16th 2012 - we were in Sri Lanka, attending the international MMM3 Meeting on Mangrove Ecology, Functioning and Management. This conference brings together researchers on topics as varied as remote sensing, gender issues, ecology and crabs! Dan gave two talks on "high-resolution mapping of mangrove topography and vegetation community structure" and "a global standardized network for monitoring mangrove vulnerability to sea level rise".
