Aqueous Leaching Prior to Dewatering Improves the Quality of Solid Fuels from Grasslands
Renewable energies are necessary to reduce greenhouse gas emissions in energy production, and biomass plays a dominant role in the renewable energy sector. Combustion of biomass constitutes an efficient conversion technique, but is hindered by harmful elements which are frequently contained in residual grassland biomass. We investigated the effect of leaching on solid fuel quality with three independent experiments including the following treatments: (1) with or without leaching, (2) with leaching at various water ...
Agrobiodiversity and nutrition in traditional cropping systems
In Uganda many farmer households have diverse agroforestry systems known as homegardens, which have been adapted over generations to supply a year-round harvest of nutritious foods. The work presented in this dissertation sought to identify the factors that influence the agrobiodiversity of these homegardens and to assess the effects of that agrobiodiversity on the health of the households that keep them. Households (n=102) were identified via stratified, random selection across three distinct regional ecological ...
