TroPeaCC: Tropical Peatlands and the Carbon Cycle
REFNo: NS310ES
Tropical peatlands are the most carbon-dense ecosystems in the world and they store the equivalent of ~10 years of global anthropogenic CO2 emissions. Despite their importance, crucial questions remain about carbon cycling in tropical peatlands and improving understanding is critical as they are at high risk from deforestation and drainage for oil palm cultivation.
TroPeaCC will provide a step-change gain in our understanding of tropical peatland functioning and in projecting their response to climate change.
PI Gallego-Sala will use her unique background that bridges peatland modelling and observations to deliver a novel interdisciplinary approach to tackle four outstanding questions about tropical peatlands:
Q1: What controls the geographical distribution of peatlands in the tropics? TASK1: To assess the tropical peatland extent using a combination of models
Q2: How large is the tropical peatland CO2 sink and what are its main climatic drivers? TASK2: To characterize the drivers of carbon accumulation rates in tropical peatlands using the palaeo-archive.
Q3: How large is the methane flux in tropical peatlands? What are the main controls at the intercontinental scale? TASK3: To determine the main controls on methane fluxes in tropical peatlands, using eddy covariance, chamber-based gas flux measurements, and ground penetrating radar.
Q4: What is the overall carbon balance of tropical peatlands and how will this change in the future? TASK4: To forecast future changes of the extent of tropical peatlands, of their carbon store and of methane emissions, using the results of tasks 1-3 to parameterise and evaluate a global dynamic vegetation model that includes tropical peatlands for the first time.
The interdisciplinary approach will lead to a comprehensive understanding of the role of tropical peatlands in the global carbon cycle, allowing their inclusion in earth system models, and improving their management to optimise provision of ecosystem services including carbon capture and storage.

Peer led outreach to engage male partners of pregnant women in Uganda
REFNo: HS2206ES
Aim 1: To assess whether a male peer-delivered, status-neutral outreach to male partners of pregnant women increases the proportion of partners who test compared to the standard of care (invitation letters for fast-track testing and HIVST delivered by the pregnant woman).
Rationale: Innovations are needed to address the challenges associated with reaching male partners of pregnant women with HIV testing and linkage to ART or PrEP depending on their HIV serostatus.
Hypothesis: A male peer delivered, status-neutral approach to male partner engagement may overcome male partners reluctance to be tested for HIV and women’s reluctance to approach their male partners about HIV testing. Approach: We will randomize women 1:1 to the intervention or delayed arm and determine the proportion of male partners who test for HIV within 1 month after the female partner is randomized. The outcome will male partner testing based on male HIV testing in the two arms.
Aim 2: To determine the proportion of male partners who test HIV-negative and have an indication for PrEP who initiate PrEP and the proportion of partners who test HIV-positive who initiate ART compared to the SOC arm.
Rationale: Men who are HIV-negative are a priority for PrEP if they have a known HIV-positive partner or multiple partners, including during late pregnancy and postpartum when men are more likely to have sex with outside partners.
Hypothesis: Trained male peers will be effective in addressing men’s reluctance to link to ART or PrEP and facilitating linkage to care or prevention.
Approach: Men who test for HIV through either arm will be referred for ART (if HIV-positive) or PrEP (if HIV-negative and reports multiple partners or an HIV positive partner) through the trained male peer counselor in the intervention arm or health care provider in the SOC arm. We will evaluate linkage to PrEP or ART among men who test for HIV, by arm.
Aim 3: To qualitatively assess acceptability of peer-delivered, status-neutral outreach to promote HIV testing among male partners of pregnant women.
Rationale: Assessment of acceptability is a key component of evaluating any novel intervention. We will use qualitative methods to investigate acceptability and preferences for HIV testing services among male partners of pregnant women in the cohort.
Hypothesis: A peer delivered, status-neutral approach to male partner engagement will be acceptable to recipients.
Approach: We will conduct individual qualitative interviews with a randomly selected subsample of 20 male partners who received peer-delivered outreach to evaluate intervention acceptability.
Population: 150 pregnant women and ?18 years of age, with male partners of unknown status, will be recruited from ANC programs in Kampala.
Study Site: The Infectious Diseases Institute (IDI) Kasangati and Kitebi Health Center III antenatal care (ANC) clinic in Kampala, Uganda
