Temporal correlation between malaria and rainfall in Sri Lanka by Briet, Olivier J.T., Vounatsou, Penelope, Gunawardena, Dissanayake M., Galappaththy, Gawrie N.L., Amerasinghe, Priyanie H.

“…However, the relationship between rainfall and the number of malaria cases is indirect and complex. Methods: The statistical relationships between monthly malaria case count data series and monthly mean rainfall series (extracted from interpolated station data) over the period 1972 - 2005 in districts in Sri Lanka was explored in four analyses: cross-correlation; cross-correlation with pre-whitening; inter-annual; and seasonal inter-annual regression. …”

A global approach to crop wild relative conservation: securing the gene pool for food and agriculture by Maxted, Nigel, Kell, S., Toledo, A., Dulloo, Mohammad Ehsan, Heywood, V., Hodgkin, T., Hunter D, Guarino, Luigi, Jarvis, Andy, Ford-Lloyd, B.V.

“…They are a critical component of plant genetic resources for food and agriculture (PGRFA), have already made major contributions to crop production and are vital for future food security; their systematic conservation in ways that ensure their continuing availability for use is therefore imperative. This is a complex, interdisciplinary, global issue that has been addressed by various national and international initiatives. …”
