Farming and fishing constitute the main economic activities of the Municipality, employing about three-quarters of the total workforce. Farming is done in almost all parts of the Municipality, especially in the inland areas and crops cultivated include cocoa, oil palm, pineapples, oranges, plantain, maize and cassava. The table below shows estimates per capita productions of key staple food [crops, livestock, and fish] in the Mfantseman Municipality. The total rainfall amount recorded in the Municipality in 2009 was 794.0mm in 78 rain days. This was low compared to the preceeding year 2008 which recorded a total of 1,192mm of rainfall in 89 rain days.
The average rainfall per quarter of the year under review recorded was 198.5mm about 100mm less that the previous year which recorded an average quarterly rainfall of 298.0mm. It was also noted that the first half of the year under review recorded more rainfall than the same period of the preceeding year but the last half of 2009 was very dry recording a total of 157mm of rainfall as against 589mm in the preceeding year. 12,582, 44452 and 96 metric tons of Maize, Cassava and Plantain are produced last year  and were all available for human consumption as there were no large scale livestock producers who grow these crops mainly to feed their livestock.The production of maize in 2009 was far less than the target of 62,000 tons.
This failure was attributed to the flood which occurred in 2009 and the long dry days thereafter. Maize, Cassava and plantain are the three most commonly cultivated crops in the Municipality. Although some crops like cocoyam, and yam are grown, they are mainly on subsistence basis as such data collection on them are very difficult.More sheep and goats were slaughtered in 2009 than the previous year. Pigs slaughtered was less than that of the previous year by 6 whiles there was no significant difference in the number of cattle slaughtered compared to that of 2008. The improvement in the number of slaughter could be attributed to the education of the public to patronize the slaughter slab and also the willingness of the clients to pay stipulated fees.
