Maize Production Responsiveness to Land Use Change and Climate Trends in Cameroon

摘要: Most studies on the responsiveness of maize production to various variables have dwelled variations in precipitation or temperature. This study seeks verify response Cameroon both climate trends and land use change. Therefore, for first time, our presents findings relative influence change Cameroon. The data used this analysis are essentially time series spanning period 1961–2006. quantity produced, area harvested number seeds planted was taken from (http://faostat.fao.org). mean growing season temperature were collected 0.5° × gridded collaborative datasets UNEP School Geography Environment at Oxford University global crop calendar dataset. analyzed using average rate change, detrended simulations, multiple linear regression technique, correlation coefficient determination. results show that is more likely responsive (forest change) than rainfall However, climatic variables, precipitation. In other words, greater loss) long run losses current gains while rising temperatures found be suitable production. Even though 1990s marked recovering levels most Sahel, large fluctuations still recorded.
