In 1869, East Africa's agricultural plan mainly focused on continuing to cultivate wasteland, just like before, prioritizing the development of land in border areas.
From Ernst's perspective, agricultural areas in the industrial era naturally serve as buffer zones, allowing population sustenance, ensuring border security, and losing agricultural land in wartime is less concerning. After all, compared to destroying an industrial zone, bombing farmland is almost painless (reference to Northeast, Ukraine), moreover, with proper post-war treatment of farmland, production can quickly resume.
Of course, this is in reference to large nations. For those countries with small territories where land resources directly threaten their survival, they must strive to seize any available land around them (reference to Israel).
If viewed as a single nation, East Africa's colony has an area of two million square kilometers, not considered small in any era.
