In 2050, Lake Dianchi might face more nutrient pollution from rivers, triggering eutrophication due to farming, city growth, and mining. Different plans affect nutrient levels variably, but the 'Optimistic scenario' with better farming and sewage controls could reduce pollution to below 2012 levels. However, even this might not completely prevent the lake from getting overpowered by nutrients, and additional measures like circular management could be crucial for avoiding eutrophication in Lake Dianchi. Efforts to control pollution from various sources are vital for keeping the lake healthy in the future.
