Analysis of spray aid's residue curve for timing fungicide applications for grey leaf spot on maize (2005)
Journal Article

Maize grey leaf spot is still a problem in commercial maize production, although the effect has been reduced with the widespread use of resistant varieties. It is estimated that, with a yield reduction of 1 %, annual economic losses of R5.6 million f...

Economic analysis of the eradication and management of invasive alien vegetation in the Mhlatuze River Catchment (KwaZulu-Natal, South Africa) (2002)
Journal Article

Alien invasive vegetation threatens the functioning and existence of natural ecosystems in South Africa because many of these plants have no predators or competitors, allowing them to dominate the ecosystem which they inhabit. The rapid proliferation... Read More about Economic analysis of the eradication and management of invasive alien vegetation in the Mhlatuze River Catchment (KwaZulu-Natal, South Africa).

SMAP Satellite Soil Moisture Products: a preliminary evaluation against COSMOS-UK estimates in Great Britain
Presentation / Conference Contribution

Satellite-based soil moisture monitoring has matured, notably as a result of the Soil Moisture Ocean Salinity (SMOS) and Soil Moisture Active Passive (SMAP) missions. Whilst spatial resolutions fall short of those ideal for field-scale monitoring, th...

Are trends in flashiness evident in natural catchments in the United Kingdom?
Presentation / Conference Contribution

Recent trend analysis in undisturbed catchments suggests a significant positive trend in high-flows and flood records over the 30–40 years analysis period ending in 2003, particularly in upland maritime-influenced catchments of the western and northe...
