I start a new thread for this to not derail one of the other yield-threads.
Do you plan to balance yields for units depending on terrain/climate?
There is a theory that european colonists unintentionally brought malaria to the americas and so they later tended to bring african slaves to work in tropic malaria infested regions since european servants as well as native slaves infected by malaria did not work well there while africans were less affected.

"The Spread to the Americas
Malaria was not referenced in the "medical books" of the Mayans or Aztecs. European settlers and the West Africans they enslaved likely brought malaria to the Americas in the 16th century.
In the book "1493: Uncovering the New World Columbus Created", the author Charles Mann cites sources that speculate that the reason African slaves were brought to the British Americas was because of their resistance to malaria. The colonies needed low-paid agricultural labor, and large numbers of poor British were ready to emigrate. North of the Mason–Dixon line, where malaria-transmitting mosquitoes did not fare well, British indentured servants proved more profitable, as they would work toward their freedom. However, as malaria spread to places such as the tidewater of Virginia and South Carolina, the owners of large plantations came to rely on the enslavement of more malaria-resistant West Africans, while white small landholders risked ruin whenever they got sick. The disease also helped weaken the Native American population and made them more susceptible to other diseases.
Malaria caused huge losses to British forces in the South during the Revolutionary War as well as to Union forces during the Civil War."
AfaIk in current design african as well as native slaves and freed workers get a general bonus of +2 for most agricultural yields for working harder than europeans. However native slaves struck by malaria were as useless as european servants for work, so in regard to malaria infested regions africans were superior workers.
In the game african slaves and freed african slaves could get a bonus for marsh and swamp yields while european and native units would get a malus (or a low base yield.) The effect in the game would become less important once all the swamp and marsh tiles get drained by pioneers.
To exploit the african perk, it would be useful to be able to "breed" african population to increase the number of workers not affected by malaria. If new born africans are treated as free persons or slaves is a difficult question. (Maybe a Founding Father could help to free africans or to at least free the new born.)
To keep the african perk, africans probably would need their own ethnic kind of expert workers for the yields of malaria infested terrain.
Weakness regarding malaria could also affect european military troops, so african troops in malaria terrain would have an advantage.
A Founding Father (introducing quinine) could be added to reduce/neglect the negative effect of malaria on europeans and natives.
Cinchona tree
Spanish missionaries found that fever was treated by Amerindians near Loxa (Ecuador) with powder from Peruvian bark (later established to be from any of several trees of genus Cinchona). It was used by the Quechua Indians of Ecuador to reduce the shaking effects caused by severe chills. Jesuit Brother Agostino Salumbrino (1561–1642), who lived in Lima and was an apothecary by training, observed the Quechua using the bark of the cinchona tree for that purpose. While its effect in treating malaria (and hence malaria-induced shivering) was unrelated to its effect in controlling shivering from cold, it was nevertheless effective for malaria. The use of the "fever tree" bark was introduced into European medicine by Jesuit missionaries (Jesuit's bark). Jesuit Bernabé de Cobo (1582–1657), who explored Mexico and Peru, is credited with taking cinchona bark to Europe. He brought the bark from Lima to Spain, and then to Rome and other parts of Italy, in 1632. Francesco Torti wrote in 1712 that only "intermittent fever" was amenable to the fever tree bark. This work finally established the specific nature of cinchona bark and brought about its general use in medicine.
It would be nearly 200 years before the active principles, quinine and other alkaloids, of cinchona bark were isolated. Quinine, a toxic plant alkaloid, is, in addition to its anti-malarial properties, moderately effective against nocturnal leg cramps.
