Applied research is very useful because this aspect is sustainable and has a wide scope at diffrrent aspects and fields like biochemistry, forestry (agroforestry, reforestation, aforestation and biodiversity consevation), medicines and also in agriculture etc.
Our country is trying to develop more and more, so, we need to solve the certain problems (Electricity, Education, Agriculture,...) by the applied research.
I prefer Theoretical research , particularly those that do not require much more than pen and paper, and a computing platform to run the ocassional numerical simulations.
