its an evaluate so 20 marker, its not that you have to answer the question that theyre impossible, its just giving examples when theres conflicts that have been solved vs when they havent been solved. this is pretty much the same for majority of evaluate and analyse questions - give contrasting examples like the example above has done.
as for conclusions, my teacher had given us a guide to what it usually the best way to answer 20 markers. i've done this question for practice and got 18 and this was my conclusion. in the body of the essay i did 1 successful example, 2 water treaties, and 1 unsuccessful and linked them to political/social/economic/environmental factors:
To conclude, solving transboundary water conflicts is complex to consider as there are multiple social, political, economic and environmental factors that make each situation different, so it is difficult to generalise. Currently, there are examples of successful management such as the Rhine River as well as unsolved conflicts such as the Nile. Compromises can be difficult to reach due to contrasting wants and needs for the involved countries, but in the future due to the climate crisis, this may worsen as there is uncertainty. Increased demand for water supply could lead to further claims and disputes so the need for more water treaties and peace talks will arise. Whilst there is potential to reach agreements, present day examples show that the effects of climate change on water supply may exacerbate political tensions as governments will prioritise their country's needs over others in order to prevent social and economic issues.Countries with differing levels of development along rivers may have be harder to appease if there are differences in power and control of the resources so in the future, all transboundary resources should be used mindfully and fairly in order to relax tensions and prevent further conflict
