Mapping smallholder farms
Remote sensing offers a low-cost way to obtain crop production statistics across large spatial and temporal scales. Yet it has been difficult to map the production of smallholder farms, given that the size of an individual field (< 2 ha) is typically smaller than the spatial resolution of most readily-available satellite imagery (e.g. Landsat, MODIS). Our work develops new methods and uses new micro-satellite data that provide high spatial and temporal resolution imagery to map the production of smallholder farms.

The impacts of natural resource degradation
Agricultural production has steadily increased across the globe in order to meet growing demand. However, this increase in production has come with associated environmental costs, including groundwater depletion and the degradation of soil health. Our work aims to understand the impacts of environmental degradation on agricultural production, how farmers respond to natural resource depletion, and ways that we may enhance sustainable agricultural practices moving forward.

Decision-making under uncertainty
Farmers are facing unprecedented shocks, including changes in weather and climate and increased natural resource depletion. Yet farmers may be able to reduce negative impacts by adapting their cropping strategies. Our research examines how farmers perceive environmental change, whether they are adopting any strategies to cope with shocks, and what the impacts of these strategies are on yield and the environment.
