The Science<\/h1>\n\n\n\n

The mechanisms that decide whether carbon stays in tropical soil<\/p>\n<\/div><\/div>\n\n\n\n

\n

Understanding tropical soil carbon in a changing climate<\/h2>\n\n\n\n

Our research addresses the “mechanistic gap” in current carbon and land-use models. Tropical soils behave differently from temperate soils. We focus on four critical aspects of fire and land-use impacts on tropical soil organic carbon.<\/p>\n<\/div>\n\n\n\n

\n

Four critical aspects<\/h2>\n\n\n\n
\n
\n
\n

Mineralogical protection & texture<\/h3>\n\n\n\n

We assess how soil mineralogy governs a soil’s capacity to protect carbon from decomposition.<\/p>\n<\/div>\n<\/div>\n\n

\n
\n

A changing climate<\/h3>\n\n\n\n

Rising temperatures and shifting rainfall will alter carbon cycling. We study soil-carbon × climate interactions across the Amazon Basin.<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

\n
\n
\n

The fire legacy: pyrogenic carbon<\/h3>\n\n\n\n

Slash-and-burn deforestation leaves behind charcoal (PyC). We are the first to assess its long-term contribution to regional carbon budgets — testing whether this recalcitrant carbon offsets some losses from burning.<\/p>\n<\/div>\n<\/div>\n\n

\n
\n

From mechanisms to models<\/h3>\n\n\n\n

We enhance the JULES land-surface model with multi-pool PyC fractions and agricultural management data (no-till, silvopasture) to sharpen global carbon projections.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
