What can we do to stop rising levels of methane?

BBC World Service - The Climate Question, What can we do to stop rising levels of methane?

Methane gas is 80 times more potent than carbon dioxide: how can we stop levels rising?

More than 100 countries signed the Global Methane Pledge at COP26 to curb methane – but emissions are rising rapidly.  What can we do about it?

Recent research shows that levels of Methane gas in the atmosphere are rising rapidly. It is over 80 times more potent as a greenhouse gas than carbon dioxide so poses a major threat to the world’s goal of limiting global warming to 1.5 C.  
At COP26, over 100 countries signed a Global Methane Pledge to reduce man-made emissions by 2030 –  experts say cutting methane emissions is ‘the most powerful lever we have for reducing warming... over the next 30 years’. 
So what can be done to stop the levels rising further? We hear how farmers in Bangladesh, along with other parts of Asia, are using wetting and drying techniques in rice paddies to reduce emissions; how cows are being fed special dietary supplements with a surprising ingredient: seaweed, but why naturally occurring wetlands are a cause for concern.
