We have extended the deadline for applications for a fully-funded PhD studentship working on the long-term ecology of Congolese peatlands at the University of St Andrews. is 18 January 2019, which fits in with other NERC DTP deadlines. The studentship is available to start on selected dates between May and October 2019. For further details please see the project advert here.
On 4th September 2018 the Tropical Wetlands Consortium (TWC) hosted a one-day stakeholder workshop, “Ecology, uses and management of wetlands and peatlands in Peruvian Amazonia”, at the Institute for Research in the Peruvian Amazon (IIAP) in Iquitos, Peru.
The aim of the workshop was to provide an opportunity for members of the TWC to present the latest research on peatlands and wetlands in the Pastaza-Marañón region and discuss with stakeholders avenues for future collaboration in the management and conservation of these environments. The wetlands and peatlands of Peru store large amounts of carbon, are economically important to local people and host unique biodiversity.
The workshop was timely as peatlands and wetlands are emerging as a conservation priority, being written into international policy instruments (such as the criteria for RAMSAR site eligibility) and attracting the interest of international donors.
The day began with an overview of peatlands and their importance, and of the latest research presented by members of the TWC (Dr Dennis del Castillo, Dr Euridice Honorio and Jhon Del Aguila of IIAP, and Dr Katy Roucoux of the University of St Andrews) with opportunities for questions and discussion. This was followed by presentations by most of the stakeholders about the work of their organisation. In the afternoon, the discussion was focused around the needs of stakeholders (what can researchers offer to support their work?) and the possibility of future collaborations to expand conservation and management efforts.
The workshop was funded by NERC, the Scottish Funding Council, and the University of St Andrews.
A new NERC-funded five-year project to study the peatlands of the central Congo basin has been announced. The project, led by Simon Lewis at the University of Leeds/UCL, involves a multidisciplinary team from the UK and the RoC. Dr Ian Lawson of the University of St Andrews is leading Work Package 1, which aims to understand the genesis and history of the Congolese peatland complex.
The project kick-off meeting took place at Leeds on 6-7 September 2018.
The project is creating several new posts, including a PDRA and PhD studentship focusing on the palynology and other palaeoecological aspects of the project. The deadline for applications for the PDRA position has passed but for further information about the studentship, please contact Ian Lawson (firstname.lastname@example.org) or see the description online. Please note that full funding is only available to UK and some EU citizens – NERC eligibility requirements are here.
More information about this exciting project is available at CarbonBrief.
We are pleased to announce three vacancies for postdoctoral research fellows, based at the University of St Andrews, to work on newly-funded projects about tropical peatlands. For further information about the posts and how to apply, please follow the link below (and narrow the search by “School of Geography and Sustainable Development.”
One of the posts is to work on the CongoPeat project, a NERC-funded Large Grant which will study the newly-described peatlands of the Congo Basin, Africa. This three-year PDRA position will focus on researching the long-term ecology of the Congo Basin peatlands (see the link for details).
Two of the posts are to work on the Valuing Intact Tropical Peatlands project, funded by the Leverhulme Trust. The project will investigate the ecology and socio-cultural value of peatlands; one of the posts is for a social scientist, the other for an ecologist (see the link for details). One further post associated with this project (in remote sensing) is currently being advertised at the University of Edinburgh.
Harvesting fruits of ‘aguaje’ (Mauritia flexuosa) palms is a profitable activity for local communities in the wetlands of the Peruvian Amazon, and potentially the key to the long-term conservation of these ecosystems. However, expanding and ensuring the sustainability of this activity depends on maintaining the ‘health’ of aguaje populations,
Aguaje is dioecious – which means that there are separate male and female individuals – and therefore sustainable harvesting depends on maintain a balance between the number of individuals of both sexes. However, typically, female trees have been felled to harvest their fruits, and in many areas, few fruit-producing trees remain.
The Peruvian Protected Areas Authority (SERNANP) is keen to promote sustainable forest management by local communities within protected areas, and aguaje fruit harvesting in Pacaya Samiria National Park is one of the most promising opportunities to achieve this goal. We are therefore working with SERNANP to support this activity, as part of our project ‘Monitoring the protected areas of Peru to increase forest resilience to climate change (MonANPeru)’ led by Tim Baker, and funded by the Gordon and Betty Moore Foundation.
Specifically, following a request from SERNANP, Karina Banda has developed a monitoring protocol for Mauritia flexuosa populations within the national system of protected areas. This protocol uses data from the network of long-term forest plots in wetland forest established by Euridice Honorio (IIAP), to identify indicators, design a sampling strategy and establish baseline values for monitoring the health of Mauritia flexuosa stands.
The plots provide crucial data on variation in two key indicators of forest health: overall aguaje density and the proportion of female aguaje trees. These data are being used to define the thresholds for these indicators, which will be used, in conjunction with regular monitoring, to identify how fruit extraction is affecting the health of aguaje stands. Implementing a clear and reliable monitoring system will help SERNANP expand aguaje harvesting to additional communities, and increase the value of the harvested fruit. For us, it is exciting to see how ecological monitoring data can be incorporated into biodiversity management to support both conservation and sustainable development in these landscapes.
From April to July 2018 Greta Dargie, Jhon del Aguila Pasquel, Julio Iriarica and Ian Lawson have been busy in the swamp forests of the Pastaza-Marañón Basin setting up monitoring sites.
At two key sites, at Nueva York and Veinte de Enero, we have installed a suite of equipment and initiated measurements aimed at measuring litter production and decomposition rates. At 14 further sites we are installing automated dipwells and litter decomposition bags. The aim is to better understand why carbon-rich peat soils accumulate in some places and not others.
Christopher, Nina, Katy and Ian spent an interesting few hours surrounded by post-it notes, thinking through how to ‘code’ (analyse) the 51 interview transcripts, amounting to something like 150,000 words, generated by our SFC-ODA project on valuing peatlands in Amazonian Peru.
Many interesting themes emerged – not least the myths, legends and superstitions that surround wetland environments in Peru – just as they do in the UK. We are also interested in themes such as resource use, sustainability, and gender issues.
Now that the decision has been taken about what to look for in the transcripts, the hard work of analysis will begin…
An article building on Tom Kelly’s PhD research at Lake Quistococha has appeared in The Conversation.
In recent years, researchers at the University of St Andrews, their colleagues at the Peruvian Amazon Research Institute (IIAP), and others have highlighted the crucial role that the Amazon’s largest tropical peatlands, located in the Loreto Department of Peru, play for the global climate due to their role as a carbon store and sink. But what about the people who inhabit these spaces? Are they aware of the existence of the peat below their feet? Does it matter to them? Do they see any threats for peatland conservation?
The collaborative project “Valuing intact tropical peatlands” (St Andrews-IIAP) aims to look at these questions for the first time, in a pilot social science research project on tropical peatlands in Peru. The peatlands in question are located to the southeast of the Amazonian city of Iquitos, and span territory inhabited by native communities and more recent mestizo settlers. One indigenous group inhabiting spaces near peatlands are the Urarina. The Urarina have their own language, culture, governance, and customs and maintain a relatively independent lifestyle, based on subsistence agriculture, hunting and fishing. They have been living near peatlands for hundreds, if not thousands of years.
Our social science research team, consisting of Christopher Schulz (School of Geography and Sustainable Development – University of St Andrews), Manuel Martín, Cecilia Núñez, and Margarita del Águila (Sociodiversity Programme – IIAP) visited an Urarina community near the Chambira River for 10 days at the beginning of April. Despite some language barriers, we were well received by the inhabitants of Nueva Unión, with whom we carried out participatory mapping exercises, interviews, and site visits to the peatlands surrounding their community.
One of the most important uses of peatlands for the Urarina are the fruits and fibres of aguaje palm trees that grow in swampy, probably peaty, areas. The women are skilled in spinning threads from aguaje fibre, which they then weave over months to produce the cachihuango, a traditional textile product among indigenous communities of the Amazon. The men frequently visit peatlands during extended hunting trips, not least because Nueva Unión is surrounded by peatlands in almost every direction; they have to be careful not to be trapped by the baainu, the evil spirit that inhabits peatlands and may make them lose their way home.
We left Nueva Unión with a positive outlook on the future of the community, and of the surrounding peatlands. Without exception people, including the young, reported being happy and satisfied with their lives in the community and planned on staying there. They did not report any major threats to peatlands, although conventional development is encroaching the area in the form of oil exploration activities and the timber trade. Nevertheless, we were also left wondering how life in Nueva Unión may change in the future, once mobile phone reception, internet, and television reach this outpost in the Peruvian Amazon, and may create a desire for change.
A new paper by Tom Kelly and other members of the Tropical Wetlands Consortium has just appeared in Journal of Quaternary Science.
As part of his PhD work, Tom showed that the lake at Quistococha, on the outskirts of Iquitos in Peru, contains a remarkable pollen and microcharcoal record. The data show an increase in pollen of the disturbance indicator Cecropia over the past century and a half, presumably reflecting the growth of Iquitos. Prior to that, the pollen record suggests little change in forest cover, despite a continuous microcharcoal record suggesting the presence of human populations.
A critical piece of evidence supporting our interpretation of the microcharcoal as an indicator of human presence was provided by co-author and archaeologist Santiago Rivas Panduro, who had previously published the results of excavations at an archaeological site adjacent to the lake. There, pottery, plant remains, and radiocarbon dates provide unequivocal evidence for prehistoric human occupation.
We suggest that the new record helps to support an emerging understanding that, in the wettest parts of Amazonia, there may have been little deforestation before modern times. This is an important qualification to the growing body of evidence from more seasonally-dry parts of the Amazon Basin which suggest that there, much of the forest had been cleared, at least episodically, in pre-Columbian times.
