Low adoption of sustainable intensification technologies hinders achievement of their potential impacts on increasing agricultural productivity. Proper targeting of locations to scale-out particular technologies is a key determinant of the rate of adoption. Targeting locations with similar biophysical and socio-economic characteristics significantly increases the probability of adoption.

2016 was the hottest year on record – the third consecutive record-breaking year. It was a sign that we have to act fast to enhance the resilience of dryland farmers, who not only have to contend with more extreme temperatures but also face rapidly depleting water resources and the destructive effects of new pests and disease.

Global demand for timber, agricultural commodities, and extractives is a significant driver of deforestation worldwide. Transparent land-concessions data for these large-scale commercial activities are essential to understand drivers of forest loss, monitor environmental impacts of ongoing activities, and ensure efficient and sustainable allocation of land.

An urgent need to stop degradation is frequently cited as support for climate mitigation efforts involving forests. However, lessons learnt from social science research on degradation narratives are not taken into consideration. This creates a risk of problematic degradation narratives being used to legitimise forest carbon projects.

Good estimates of ecosystem complexity are essential for a number of ecological tasks: from biodiversity estimation, to forest structure variable retrieval, to feature extraction by edge detection and generation of multifractal surface as neutral models for e.g. feature change assessment. Hence, measuring ecological complexity over space becomes crucial in macroecology and geography.
