Stem rust is a potentially devastating fungal disease that can kill wheat plants and small grain cereals, but more typically reduces foliage, root growth, and grain yields. The pathogen multiplies rapidly, and its spores can be dispersed by wind over thousands of kilometers.
Risk: we all know what that means, right? But why is it such a critical part of our HarvestChoice portfolio, what does it mean when you look through the lens of farming in Sub-Saharan Africa?
The definition of risk used by the HarvestChoice project does not frame risk as inherently bad. After all, farmers and other individuals often voluntarily subject themselves to risks that can be avoided. That is, some individuals may view risk as undesirable, others may not care, while still others may view it as desirable. Individuals who find risk undesirable are commonly referred to as risk averse. Individuals who do not care are commonly referred to as risk neutral. Individuals who find risk desirable are often referred to as risk preferring, loving, or attracted.
Just wrapped up three days in Nairobi with our colleagues at the Regional Strategic Analysis and Knowledge Support System (ReSAKSS), pulling together agricultural production and research experts from around East and Central Africa to share our tools and learn how we can make our data products work better for them.
Not only crop growth and yield, crop models can be also used to estimate potential damages from pest/disease through a predefined set of damage pathways, or coupling points.
Farming entails a great deal of choices and uncertainties. From season to season, weather varies, price fluctuates, soil degrades, pest damages, and climate changes. Farmers everywhere must cope with these uncertainties. Throughout the history of agriculture, many options have been developed to help manage these risks, increase yields, increase efficiency, and, more recently, promote the sustainability of the overall system.
