Forests and human health

Forests and human health | Complex Insight  - Understanding our world | Scoop.it

This 2009 publication from the FAO’s Forestry and Forest Products Division highlights why emerging infectious diseases are considered to be among today’s major challenges to science, global health and human development. Rapid changes associated with globalization, especially the rapidly increasing ease of transport, are mixing people, domestic animals, wildlife and plants, along with their parasites and pathogens, at a frequency and in combinations that are unprecedented.

ComplexInsight's insight:

This prescient report from the FAO in 2009 highlights why research on EIDs, particularly that involving the ecological epidemiology of zoonotic and vector-borne diseases associated with forests, needs to be integrated with forest resource management and planning and healthcare management planning. This report along with related publications from FAO are essential reading for anyone modeling ecological change and disease impact. Very much worth reading.

Spatial Patterns and Spread of Potato Zebra Chip Disease in the Texas Panhandle

Spatial Patterns and Spread of Potato Zebra Chip Disease in the Texas Panhandle | Complex Insight  - Understanding our world | Scoop.it

Zebra chip (ZC, also known as papa manchada and papa rayada) is a disease that is affecting potato production in the southwestern United States and in other countries, and which has been linked to potato psyllids (Bactericera cockerelli, which infests both potatoes and tomatoes) that harbor the bacterial plant pathogen ‘Candidatus Liberibacter solanacearum’.

 

Until recently, the epidemiology of ZC was unknown, motivating research to elucidate the spatial and temporal patterns of ZC infections in potato fields. Studies were performed in multiple commercial potato fields located in the Texas Panhandle, wherein locations of ZC-affected potato plants were georeferenced or counted within large plots and along belt transects consisting of contiguous 10-by-10-m quadrats. The frequency of ZC infections within belt transect quadrats was well described by negative binomial and zero-inflated negative binomial distributions, in agreement with observed clustering of infections and distance-based spatial statistical results.
