Dear teachers,

I'm reading an article about Zimbabwe and cannot understand the meaning of these expressions: "choice tracts" and "charged issue".

Here's the relevant excerpt:

"The economy centers on farming, mining (Zimbabwe holds a tenth of the world's chromite), and manufacturing. Until drought struck in the early 1990s, the nation fed itself. Whites still own choice tracts, and land redistribution is a charged issue".

I would be glad if you could help me.
