Most of the time there are generally two possibilities when selecting a topic: you can apply for a topic advertised by supervisors or select one freely. Both options have their advantages and disadvantages. The advantage of choosing a topic already announced is that this topic is more likely to be integrated into the work of a research group resulting in close mentoring (Bopp et al. 2000: 57). However, your own ideas may not always be considered in this case.
If you choose a topic freely there will be much more room for creativity and personal contribution but perhaps also fewer opportunities to find peers in difficult times. When concentrating on writing a longer piece of work - such as a bachelor's or master's thesis - it is advisable to choose a topic that truly reflects your interests. This doesn't guarantee good questions or wise topic selections; however, you are more likely to keep up the good work and develop new ideas (Bänsch 1999: 33).
When choosing a topic freely you may spend more time with precedent clarifications or adaptations. You should make sure that the topic selected matches the department's and supervisor's line of research, is reasonable as regards its time frame, and is based on a sound literature review.
However, it is not wise to only choose a topic because there is a lot of further reading material. On the one hand, it is then difficult to focus on a particular subject and on the other hand, it isn't the quantity but the quality that counts (Bänsch 1999: 35).
When having a say in the matter you should seize the opportunity, consider your interests and abilities while asking yourself amongst other things:
When writing a master's thesis it is not necessary to explore completely new intellectual spheres. You should choose a topic already discussed in lectures, seminars or even everyday life, one that can be tackled in a given period of time (Krämer 1999: 16–17).
How is the local population influenced by land acquisitions for the production of biofuel?
How does tourism influence the local population of exotic countries?
Why does the acquisition of land by foreign investors cause problems for the local population? What are the advantages for the donor country?
Why is it necessary to buy land from a state? What are the reasons for land grab?
Should biofuel replace/complement traditional fuel? What are the advantages and disadvantages?
What is the relation between globalization and land grab?
In addition to social sciences it is mainly geography that has turned out to be a problem-oriented branch of study when dealing with environmental change, globalization, statistical data processing, etc., and trying to find solutions to these problems academically. Even a lecture's or seminar's topic can be qualified as a problem that has to be described, analyzed, and finally solved.
However, in geography problem-oriented research and epistemological research continue to exist side by side. One doesn't only focus on a concrete problem but rather strives to get certain knowledge of a particular issue or e.g. a community. When doing academic research the way of posing a problem determines the superior framework or subject area, respectively. It defines the gist of the matter.
Example: «Tourism can cause social changes in so-called developing countries.»
Posing a question (or even more than one) deals with that part of a problem that has to be explored first and in more detail. It precedes the research, is derived from the problem, and should therefore be solved during the course of your writing if possible. Posing a question should to some extend contribute to a problem's solution.
An academic paper focuses on the questions posed.
Trying to find good questions is one of the most challenging tasks when doing academic research. Without clearly defined questions you risk going overboard. It is therefore necessary to take your time and refer to these questions over and over again.
Example: «What effect does tourism have on children going to school in a region faced with poverty?»
The process of developing reserach questions is only completed after analyzing all relevant data. In general, a good question isn't determined from the very beginning but only becomes apparent after familiarizing yourself with the matter. It is also legitimate to make modifications or rephrasings. Theoretical pieces, models or methods applied on recent fields of research can be sources for good questions, as well as scientific papers or topics of public discourse, etc. (Bopp 2000: 57). When wanting to concretize a question it can be worthwhile to exchange views with fellow students in a similar situation. Preconceptions and fixed ideas can then be challenged while bearing in mind a wide range of aspects and issues.
