In 1874, East Africa was not particularly proactive in investing in agriculture. Other than expanding inland cultivation areas, no other policies had been implemented.
By April of this year, the immigrant population in the Zambia region had surpassed 500,000. They were spread throughout the region in the form of villages and towns. Together with the southern plateau region of the Congo, the total population stood at around 800,000.
During the same period, Zimbabwe's population had just exceeded 150,000. Although its population was not large, its growth rate was the fastest.
Apart from these three regions, population growth in all other areas totaled around 300,000, including South Africa, the eastern plateau region of Angola, the White Nile River basin, the Azande Plateau, and the Okavango River Delta. Among them, immigration to South Africa and the eastern plateau region of Angola was primarily needed to consolidate the borders. In places without such needs, such as the Okavango River Delta, the population had increased by only a little over 3,000.
"From Dar es Salaam Port and Mtwara Port to Mbeya, a complete immigration route has already taken shape. Immigrants were diverted in South Salzburg Province by land and through Lake Malawi. This was an important reason why the population in the Zambezi River basin and the southern Congo River basin could grow so quickly."
"During the same period, agricultural development on both the northern and southern banks of the Zambezi River basin improved significantly. Apart from the steady expansion of the planting areas for the two major staple crops, rice and wheat, tobacco was an important cash crop, while sisal and similar crops also developed at a particularly rapid pace."
"Population growth in the inland regions has also added quite a bit of trouble to our work, mainly in terms of administrative efficiency.
