During my two-week fieldwork trip to Peru this summer, I visited two of my PhD study areas, the Ancash District and the Chillón Valley. The Chillón Valley is home to one of the three main rivers that provide water for Lima and activities in this valley can have major effects on Lima’s water supply. Ancash on the other hand is home to two of the main mountain ranges in Peru, the Cordillera Negra and the Cordillera Blanca, so called because the former is unglaciated whilst the latter is formed of a number of glaciated peaks. It is thought that the Cordillera Blanca may one day look like the Cordillera Negra if glacial retreat continues at its current rate; this contrast between the two was interesting to see as the absence/presence of glaciers also affects the availability of water for irrigation and farming.
Whilst in Ancash we held a community workshop with representative from the local communities around the village of Pamporamas, in the Cordillera Negra, and a representative from a local NGO focused on rural development. This workshop discussed the issues surrounding water availability, and changes in this availability, as well as agricultural productivity within the highly sensitive Cordillera Negra. Following our workshop we visited a number of sites within the Cordillera Blanca, this involved visiting farming communities and seeing how agriculture is practiced today but also saw evidence for past agricultural practices in the form of relic terraces and field systems which would have been in cultivation during pre-Columbian times. We also interviewed local farmers whilst in the field to discuss the present day issues effecting agriculture productivity and sustainability within the study areas. This was an excellent opportunity to record local oral histories about changes in farming practices within living memory, to go alongside the deeper history perspective provided by the sediment core records we also collected.
A thousand years ago in southern Brazil, the unique Araucaria forest expanded rapidly over highland grasslands (campos), a change that’s largely been attributed to climate changes. At the same time, the southern proto-Jê people, whose diets and culture were interwoven with Araucaria trees, flourished. Given the close connections between the people and trees, and the timings of their expansions, might the Jê have been more important for that last forest expansion than the climate? So far, concrete evidence to address this question has been lacking – but two recent studies set out to provide just that.

When was the last time you looked around you and wondered, ‘How on Earth did I get here?!’
I had one of those moments – possibly the biggest of my career so far – on April the 10th, in the Royal Institution‘s iconic lecture theatre. In one sense I knew the answer (from Kent via Victoria and Green Park underground station), but even now, two weeks after the event, I’m still trying to wrap my head around how I came to talk about my PhD research from the same spot as such renowned science communicators as David Attenborough, Richard Dawkins and Carl Sagan.

Just before Christmas last year I was offered a place on the first Climate Services Academy Training (CSAT) programme. As someone who has been interested in the science-policy interface for a long time, particularly around climate issues, I was delighted with my early Christmas present from the Walker Institute (@WalkerInst on Twitter).
When the programme kicked off in mid-January, I knew I was in for a treat. The first two weeks were spent at the University of Reading where we were taken on a whirlwind tour of the topics we’d need to understand to work on ‘climate services’ (think ecosystem services, but for the climate). Topics included communication for development, international risk management law and governance, livelihoods analysis, politics and political economy, and knowledge exchange. This was followed up by a week of intense ‘scenario days’ where we were given a real-life climate or environment related issue that is currently ongoing in one of the programme’s partner countries (Senegal, Malawi, Ghana and Uganda) to read up on and report back on at the end of the day. I learnt an enormous amount in those two weeks, but we were just getting started.
(This is part 2 of a 2-part post where a Jungian psychological approach is taken to analysing the history of the West’s relationship with the Amazon rainforest. I recommend you read part 1 if you have not already done so.)
In the late 19th century thinkers like Muir and Thoreau fused insights from Eastern philosophy, Romanticism and natural science, sparking a public interest in ecosystems as spiritual and leisurely places. President Roosevelt established the National Parks system, officially designating certain landscapes as protected wilderness. Designations were partly pragmatic decisions to conserve resources but perhaps more importantly made on a landscapes ability to ignite the feeling of awe. Yellowstone National Park was the first wilderness protected area in the world, but the model spread rapidly across the globe making its way to the Amazon. From this combination of ideas rose the applied science of biological conservation. In the same way Amazonia became the archetypal frontier to Imperial expansionists due to its size and vegetative fecundity, it became the ultimate wilderness in need of protection, in the minds of the conservationists.

Humans throughout history have dedicated immense amounts of energy to understanding forests. When we think of human-forest interactions, often cited are the direct products we take from forests, the indirect benefits environmental services and the issues of sustainability. Yet rarely mentioned is the psychological relationship we have with the forests and the potential implications on forest management. In this blog I take a mythological Jungian approach in analysing the history of Tropical Palaeoecology, so we might better understand the unique psychological link that the West shares with Amazonia. This blog is part 1 of 2. It is a briefing of my ideas and as a result touches only shallowly on the highlights of my thinking. I hope to go deeper into these thoughts in future blogs.
The way we perceive the world has been shaped by our evolutionary history within and later outside of the forest environment. In negotiating trees, we started to see in three dimensions, so we would not fall from branches. It was only when leaving the forest that we broke free of our primate shackles, stood upright and became Homo sapiens. As a result, the dualistic nature of the forest as both a nurturer and tyrant are burnt deep into our subconscious.
Last month I was lucky enough to undertake a phytolith training placement at the University of Exeter in the Department of Archaeology, working with my second PhD supervisor, Professor Jose Iriarte, and his project team, PAST (Pre-Columbian Amazonian Scale Transformations).
During my four-week stay in Exeter, I processed and extracted phytoliths from a soil profile in the Upper Tapajos Basin of the Amazon, associated with a ditch enclosure. Once extracted, I then analysed and got training in the identification of the phytoliths. The phytolith extraction process can be quite lengthy and so it was great to have a lot of time to work through each of the stages properly. I had previously done some phytolith extractions for my master’s dissertation, however, I wanted to learn the methodology most suited to the tropics and South American samples.
I’ve found science fascinating for a great many years, and one of the things I enjoy most in life is helping others to catch some of that fascination for themselves. It’s a big part of the reason why I became a teacher before I started my PhD, and I’m so glad that science communication and outreach opportunities have continued to appear since then – after all, research shows it’s good for you, and for others. In this post, I want to reflect on some of the outreach fun I’ve had in the last year, and maybe encourage you to have a go too!
Fascination of Plants Day 2017 – the event that kicked it all off…
By Richard Smith
Hello, and happy new year! In this blog post I’d like to briefly tell you about my first paper that was accepted and published in the journal Quaternary Research in late 2017. It’s entitled “Impact of mid- to late Holocene precipitation changes on vegetation across lowland tropical South America: a paleo-data synthesis” and can be found here.
In late 2016, Frank was approached by Mark Bush who wanted to prepare a collection of papers for a ‘special issue’ to honour the lives of two prominent palaeoecologists, Prof. Paul Colinvaux (1930-2016) and Prof. Daniel Livingstone (1927-2016). Both Paul and Daniel were leading figures in tropical palaeoecology, with Paul focusing predominantly on tropical South America and Daniel in tropical Africa. Throughout their careers, they were at the forefront of much of the breakthroughs in tropical palaeoecology, as well as inspiring and training many graduate students to create an international legacy of palaeoecologists. More can be read about their amazing careers in Mark Bush and Will Gosling’s tribute article: “In search of the ice age tropics, a tribute to Prof. Daniel Livingstone and Prof. Paul Colinvaux”.

Given the focus as Paul and Daniel’s careers, the special issue was to focus on South American and Africa palaeoecology. Frank suggested that I take this opportunity to write a paper to submit to this special issue on some work I had completed previously, synthesising existing palaeoecological data from across tropical South America from the mid-Holocene to the present. So that is what I did! Continue reading
Happy New Year! Josie and I got 2018 underway with three days in Plymouth, dodging the disruptive effects of Storm Eleanor at the QRA annual discussion meeting. It was an enjoyable conference, showcasing a variety of research relevant to our work.
