Consumption of water that is contaminated with pathogens still causes high numbers of death and disease. Understanding the factors that influence the dynamic distribution of waterborne pathogens is important, as this will help understanding improvements and possible solutions. Such understanding is particularly important in a developing country lik...
Agricultural production has kept pace with the population growth (FAO, 2012). One major input for a productive agriculture are fertilizers. Despite their effect on yield and quality, they also have considerable effects on the environment leading to emission of greenhouse gases, acidification, eutrophication and use of scare resources (Ruttan, 2002;...
