reforestation

Explanation:

In the past decade, multiple African nations have been working together on projects that have the purpose to stop and reverse the land degradation. For this purpose, the people that live in the areas where the soil has been badly damaged or has been affected by the process of desertification have been mobilized, educated, and motivated to perform a reforestation. The reforestation generally has been taking place along the northern border of the region where it touches the outskirts of the Sahara Desert. The results have been excellent. The trees that have been planted are trees that produce fruits, thus food, they contributed to making the soil more fertile but also much more resilient to erosion, and the wells have started to replenish their water because of the protection from the trees above them that significantly reduce the evaporation.

As someone who have lived in northern moravia at industrial steel and coal city of ostrava, the closest point is b), but it is questionable. i am not sure how to compare efficiency of largest steel mill in czech republic in comparison to china which is the biggest exporter, but czech steel factories were modernized and run more efficient that 25-35 years ago, and been privatized and owned by mittal. the workforce had been shrinking, so not exactly sure what that c is pointing to (aging of workforce, size of it, or quality). northern moravia is a part of larger coal basin that extend to poland with large coal deposits. this was foundation for the steel industry in the 1800's together with large ore deposits that was mined in proximity of the beskidy mountains less than 25 miles from ostrava. the iron ore mines had been depleted for several decades, and since the late 70's when communists run the country, they were already importing soviet iron ore. coal mining within city of ostrava cased to exist in the 1990's due environmental issues, and also cost. the mines were getting deeper and more costly to operate and there is no more mining within ostrava. couple mines are still in operation in karvina county which is next to ostrava. currently the coal deposits south of the city were not opened due environmental issue which would mean destruction of third largest mountain range in the country. therefore, my conclusion is is b, as the ore and coal resources been shrinking. the biggest challenge not mentioned here is of course competition from russia, ukraine, and china, which can produce steel much cheaper.
