Improved storage technique and management of aflatoxin in peanut production: Evidence from Northern Ghana

Scientific African, 2020
Peanut production contributes to food security in northern Ghana due to its ability to tolerate drought and survive on marginal lands. This notwithstanding, poor handling along the value chain favors aflatoxin contamination, a threat to human and animal ...

Factors that Determine Aflatoxin Infestation in Ghana: Application of Cragg's Double Hurdle Model

Sustainable Futures, 2020
In our application of Cragg's (double hurdle) model, we explicitly address functional form misspecification by first using nonparametric regression to identify the functional relationship between aflatoxin infestation and a vector of agronomic and ...
