Rice farmers in the Philippines have found an ally as they try to protect their crops from pests and the effects of global warming.
Farmers use ducks to help keep the water in their paddies fresh, and to get rid of weeds and other pests that could damage their crops.
Duck manure also works as a good organic fertiliser, which helps to decrease the amount of money farmers spend on harmful pesticides.
Integrated rice-duck farming was first introduced to the country in the early 1990s. However, it has not been easy to convince more farmers to let go of their dependence on chemicals.
