Journal Article

The three-peat challenge: business as usual, responsible agriculture, and conservation and restoration as management trajectories in global peatlands (2023)
Journal Article

Peatlands are a globally important carbon store, but peatland ecosystems from high latitudes to the tropics are highly degraded due to increasingly intensive anthropogenic activity, making them significant greenhouse gas (GHG) sources. Peatland resto... Read More about The three-peat challenge: business as usual, responsible agriculture, and conservation and restoration as management trajectories in global peatlands.

The contribution of natural burials to soil ecosystem services: Review and emergent research questions (2023)
Journal Article

The modern funeral industry faces many environmental risks and challenges, such as the use of sustainable materials for coffins, the release of potentially damaging materials and organisms to the soil and groundwater, and reduced space available for...

Simulating carbon accumulation and loss in the central Congo peatlands (2023)
Journal Article

Peatlands of the central Congo Basin have accumulated carbon over millennia. They currently store some 29 billion tonnes of carbon in peat. However, our understanding of the controls on peat carbon accumulation and loss and the vulnerability of this...

Opportunities for enhancing the climate resilience of coffee production through improved crop, soil and water management (2023)
Journal Article

Climate change is adversely affecting coffee production, impacting both yields and quality. Coffee production is dominated by the cultivation of Arabica and Robusta coffee, species that represent 99% of production, but both will be affected by climat...

Mapping Water Levels across a Region of the Cuvette Centrale Peatland Complex (2023)
Journal Article

Inundation dynamics are the primary control on greenhouse gas emissions from peatlands. Situated in the central Congo Basin, the Cuvette Centrale is the largest tropical peatland complex. However, our knowledge of the spatial and temporal variations... Read More about Mapping Water Levels across a Region of the Cuvette Centrale Peatland Complex.

Towards net zero in agriculture: Future challenges and opportunities for arable, livestock and protected cropping systems in the UK (2023)
Journal Article

The agricultural sector faces multiple challenges linked to increased climate uncertainty, causing severe shocks including increased frequency of extreme weather events, new pest and disease risks, soil degradation, and pre and postharvest food losse...

Tropical peatlands in the Anthropocene: The present and the future (2022)
Journal Article

Tropical peatlands are a globally important carbon store. They host significant biodiversity and provide a range of other important ecosystem services, including food and medicines for local communities. Tropical peatlands are increasingly modified b...

Hydroclimatic vulnerability of peat carbon in the central Congo Basin. (2022)
Journal Article

The forested swamps of the central Congo Basin store approximately 30 billion metric tonnes of carbon in peat . Little is known about the vulnerability of these carbon stocks. Here we investigate this vulnerability using peat cores from a large inter... Read More about Hydroclimatic vulnerability of peat carbon in the central Congo Basin..

Mapping peat thickness and carbon stocks of the central Congo Basin using field data (2022)
Journal Article

The world’s largest tropical peatland complex is found in the central Congo Basin. However, there is a lack of in situ measurements to understand the peatland’s distribution and the amount of carbon stored in it. So far, peat in this region has been...

Immediate environmental impacts of transformation of an oil palm intercropping to a monocropping system in a tropical peatland (2022)
Journal Article

The expansion of oil palm plantations is one of the greatest threats to carbon-rich tropical peatlands in Southeast Asia. More than half of the oil palm plantations on tropical peatlands of Peninsular Malaysia are smallholder-based, which typically f...

Linking long-term soil phosphorus management to microbial communities involved in nitrogen reactions (2022)
Journal Article

The influence of soil phosphorous (P) content on the N-cycling communities and subsequent effects on N2O emissions remains unclear. Two laboratory incubation experiments were conducted on soils collected from a long-term (est. 1995) P-addition field...

Tropical peatlands in the anthropocene: Lessons from the past (2022)
Journal Article

The status of tropical peatlands, one of Earth's most efficient natural carbon stores, is of increasing international concern as they experience rising threat from deforestation and drainage. Peatlands form over thousands of years, where waterlogged... Read More about Tropical peatlands in the anthropocene: Lessons from the past.

Identifying Sustainable Nitrogen Management Practices for Tea Plantations (2022)
Journal Article

Tea (Camellia sinensis L.) is the most widely consumed beverage in the world. It is mostly grown in the tropics with a heavy dependence on mineral nitrogen (N) fertilisers to maintain high yields while minimising the areas under cultivation. However,...

Spatial variability of surface peat properties and carbon emissions in a tropical peatland oil palm monoculture during a dry season (2021)
Journal Article

The expansion of oil palm monocultures into globally important Southeast Asian tropical peatlands has caused severe environmental damage. Despite much of the current focus of environmental impacts being directed at industrial scale plantations, over...

Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture (2021)
Journal Article

Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify the concentration and thermostability of soil organic matter associated with soil aggregates. Understanding the thermostability and carbon r... Read More about Long‐term zero‐tillage enhances the protection of soil carbon in tropical agriculture.

Expert assessment of future vulnerability of the global peatland carbon sink (2020)
Journal Article

© 2020, The Author(s), under exclusive licence to Springer Nature Limited. The carbon balance of peatlands is predicted to shift from a sink to a source this century. However, peatland ecosystems are still omitted from the main Earth system models th... Read More about Expert assessment of future vulnerability of the global peatland carbon sink.
