How will climate change affect agricultural water management?

Climate change is altering rainfall patterns and temperatures, potentially affecting growing seasons, irrigation needs, and agricultural drainage systems. Will warmer temperatures allow earlier planting? Could longer growing seasons increase irrigation demands? And will heavier rainfall place additional pressure on drainage infrastructure? Drawing on research in Sweden and Bolivia, this talk combines historical weather observations and future climate projections to explore how agricultural water availability and management challenges may change in the coming decades, and how farmers can better prepare for these changes.
Water and soil N₂O – a well understood mechanism, a poorly quantified flux
Sebastian Piotr Kusmierz, postdoctoral researcher
Agricultural water management group, Department of Soil and Environment
The water table is the main variable altered by agricultural drainage and peatland rewetting and a first-order control on soil nitrous oxide (N₂O) production. While the underlying processes, nitrification in aerated pores and incomplete denitrification in the capillary fringe, are well established, their translation into quantitative estimates remains weak. A large share of N₂O is released during short-lived hot moments that low-frequency chamber measurements misses and models reproduce poorly. National inventories do not account for water-table dynamics at all: fixed emission factors are applied per land-use class, and N₂O from rewetted organic soils is assumed negligible. Consequently, the N₂O response to drainage and rewetting and even heavy rainfalls remains unquantified, both in magnitude and in sign. This talk identifies where this knowledge gap arises, from pore to inventory, and outlines ongoing research to make N₂O estimates more accurate.
