Suggest two measures that can be put in a place by government and non-governmental organizations to manage river systems at risk due to deforestation

1. Government could implement regulations and policies to protect the forests and regulate logging activities near river systems. This may include creating buffer zones along the rivers where logging is prohibited, enforcing sustainable logging practices, and promoting reforestation efforts in areas that have been deforested.

2. Non-governmental organizations can work with local communities to raise awareness about the importance of maintaining healthy forests for the health of river systems. They can also engage in conservation efforts such as planting trees along riverbanks, conducting clean-up activities to remove debris that may be negatively impacting the river, and working with local stakeholders to develop sustainable land use practices that protect the environment.
