During the 2015 monsoon, more than 30 people in Nepal's Kaski district were killed in landslides. People are preparing for the future with protective walls and drainage ditches, but the latest hope is a plant: broom grass, known locally as amriso.

Megan is 15 and loves music. She plays guitar and piano and likes to learn songs she's found on the internet. But she's also a team player - on her school's volleyball team. On the playing court, she says, she gives her all and enjoys posing difficulties for her opponents as a setter. Like many Australians, Megan also has roots abroad.

Her parents come from the Philippines. That's why she and her family often spend their holidays there.

During the monsoon in July 2015 more than 30 people in Nepal's Kaski District were killed in landslides. Climate change brings torrential rains more and more often. People are using protective walls and drainage ditches to protect themselves. But one new hope is a plant: amriso, commonly known as broom grass.

Its roots anchor soil very effectively, store water and curb the floodwaters plunging into the valleys. In this way, amriso raises the chances of survival for the people living in the extremely steep, partially deforested Himalayan region. It's hoped the fast-growing plant will better protect the traditional terraced fields and the roads and houses carved into the mountains from mudslides. And it has even more advantages: using broom grass saves firewood and women can sell home-made amriso brooms to top up the family income. The International Union for the Conservation of Nature (IUCN) is maintaining small experimental fields, but there has already been success with cultivating amriso on large slopes at risk of erosion.

On 9 July 20111 a dream came true for people in South Sudan. Its declared independence marked the beginning of a new era that promised an ecomomic upswing and an end to famine and poverty. But the hopes for a better future have been dashed.

A violent civil war is raging between the two major ethnic groups over control of this young country. Fifty thousand people have died in the conflict. And to make things even worse, the entire region is suffering acute water shortages.
