La pérdida de importancia económica de la caficultura en Colombia, tanto en el contexto nacional como en el internacional, se explica, principalmente, por la caída dramática de su productividad; el consiguiente empobrecimiento de los caficultores, así como por el envejecimiento de estos y de...

The efficacy of “gaseous” ozone in reducing numbers and re-growth of food-borne pathogens, (<i>Escherichia coli </i>and<i> Listeria </i>spp.), on leafy salads was investigated using spinach. A preliminary<i> in vivo</i> study showed 1-log reduction in six strains of <i>E. coli</i> and two species of <i>Listeria</i> spp. on...

<i>Listeria monocytogenes</i> contamination of cantaloupes has become a serious concern as contaminated cantaloupes led to a deadly outbreak in the United States in 2011. To reduce cross-contamination between cantaloupes and to reduce resident populations on contaminated melons, application of...

Food production in 2050 will be sufficient, globally, but many of the poor will remain food insecure. The primary cause of food insecurity will continue to be poverty, rather than inadequate food production. Thus, policies and investments that increase the incomes of the poor will remain the...

Excessive salt rate can adversely influence the physical, chemical, and biological properties of soils, mainly in arid and semi-arid world regions. Therefore, salt-affected soils must be reclaimed to maintain satisfactory fertility levels for increasing food production. Different approaches have...

This paper investigates the impacts of non-traditional exports on household outcomes in rural Zambia. It is the attempt to identify and estimate second round effects that distinguishes this paper from most of the current literature. We study the impacts on income, child health and education...

This study examines the Chilean experience of economic and trade reforms, deregulation and privatization beginning in the 1970s, and their effect on the agricultural sector from the 1980s to the present. Especially interesting is the interaction between the sectoral, macroeconomic and...

In terms of species richness, arthropods may represent as much as 85% of the soil fauna. They comprise a large proportion of the meso- and macrofauna of the soil. Within the litter/soil system, five groups are chiefly represented: Isopoda, Myriapoda, Insecta, Acari, and Collembola, the latter...

The benefits of biochar to soils for agricultural purposes are numerous. Biochar may be added to soils with the intention to improve the soil, displace an amount of conventional fossil fuel based fertilizers, and sequester carbon. However, the variable application rates, uncertain feedstock...

Chicken litter or chicken litter-based organic fertilizers are usually recycled into the soil to improve the structure and fertility of agricultural land. As an important source of nutrients for crop production, chicken litter may also contain a variety of human pathogens that can threaten...
