  • Review of the effects of energy crops on hydrology. 
    Stephens, William; Hess, Tim M.; Knox, Jerry W. (2001-02-15)
    1) MAFF has recently launched a scheme to support the expansion of the area of energy crops grown in England in order to meet the nation’s Kyoto targets for the reduction in CO2 emissions. This has highlighted concerns ...
  • Soil variability effects on the yield of winter wheat under variable-rate nitrogen applications 
    Miles, Daniel (Cranfield University, 2016-05)
    Seven UK fields located across Oxfordshire, Southampton and W. Berkshire, five cropped in winter wheat in 2014 and two in 2013 were investigated to assess the effect of soil variability on mean yield and yield variance ...
  • A study of obesity drivers in Mexico using alternative future scenarios to define policy, 
    Anguiano Arreola, Paulina (Cranfield UniversitySWEE, 2022-02)
    In the last four decades, Mexico has experienced a rise in the prevalence of obesity among urban households, increasing the risks of comorbidities and premature deaths. This PhD thesis examines what is driving obesity ...
  • Sustainable water management for sweetcorn in Senegal 
    Kaiser Lopez, Pablo (Cranfield University, 2012-10)
    Water consumption is a global concern, especially in the agriculture sector in sub-Saharan countries, where 70% of abstraction is for agricultural use. This study was undertaken to evaluate the role of scientific scheduling ...
