Heterogeneous effects of sustainable agriculture practices: micro-evidence from Malawi
2020
Abstract Are the effects of sustainable agricultural practices heterogeneous across agro-ecology and wealth in Malawi? Would a wealth-enhancing policy be associated with increased effectiveness of these practices? Focusing on a nationally representative set of Malawian agricultural households, the article answers the above questions by employing plot-level panel data matched with a set of geo-referenced rainfall and temperature records. The findings suggest a positive correlation between aggregate yield and the adoption of organic fertilizer. A similar result holds for legume intercropping and for hybrid seeds, which are associated to reductions in yield volatility between the two waves. Ne…
Drug Resistance in Salmonella enterica ser. Typhimurium Bloodstream Infection, Malawi
2014
To the Editor: Salmonella enterica serotype Typhimurium is one of the most common causes of bloodstream infection in sub-Saharan Africa (1). Among adults, the principal risk factor for invasive nontyphoidal Salmonella (iNTS) disease is advanced HIV infection; up to 44% of HIV-infected patients experience bacteremic recurrence through recrudescence of the original infection (2,3). Epidemics of iNTS disease in sub-Saharan Africa have been associated with a novel genotype of S. enterica ser. Typhimurium of multilocus sequence type (ST) 313 that is rarely seen outside the region and is associated with multidrug resistance (MDR) to chloramphenicol, cotrimoxazole, and ampicillin (4,5). As a conse…
