Indonesia, Ben Brown, United Nations discussed on BBC World Service


Now all this week. We're looking at ecosystem renewal what why well because if you weeks ago the United Nations announced a ten year plan to restore more than three hundred fifty million hectares of degraded land by twenty thirty today. We're looking at the part mangrove forest could play in this snow on paper. It could be a very big part mangrove forest natural carbon sing storing around four times as much carbon than tropical forests. They also protect the land from erosion during storms Indonesia has more mangroves than any other country. But it's a lost nearly half of all the mangroves at once had now it holds yearly replanting sessions, but plastic sessions don't always work. Ben Brown is a mangrove expert, and he told us small I work with coastal communities. Most of my the last twenty years, and for them mangroves are just about everything the source of their fish protection from storms fuelled would when they need it. And really when the Caesar off. And you don't catch anything deep. Itsy mangroves. You can always come back to the fisherfolk feel like it's their refrigerator away or their supermarket. Yeah. They have shrimp. Clams fish things like that they break down really slow. So they store carbon for a long time. And they start quite a lot of it mostly under their soil. So if you disturb the trees, you end up disturbing the soil, and that carbon is released in the mid it back into the atmosphere, which we're all trying to avoid so all day under threat told by what's going on in terms of climate change. I'd say they're under threat in two ways. So like directly from some human activities, still and indirectly humans again through climate change mangroves only grow in a very specific zone between means e level and high tide and as some of us know sea levels rising coastal communities here in Indonesia note, for sure because their houses are flooded and underwater when they didn't used to be and mangroves to keep up with that. We'll have to migrate a little bit inland. Nd but inland. There's all these things that humans have put their villages and roads hotels, banks cities. We have a term we call it accommodation space where areas can accommodate mangoes, and that's getting less and less. Unfortunately, one thing people try to do is restore mangoes, which is of course. Good. But all too often people plant mangroves where they used to belong or a little too far out to sea below mean sea level where they drown right away. Where you can't it won't work. It's also estimated that up to ninety nine percent of mangrove planting projects have failed worldwide is it because of the space or not planting it in the right position. Yeah, it's pretty much exactly that and there's probably two reasons. One is people don't necessarily know where mangroves belongs. So that's pretty easy to solve. But the other thing is where mangroves should be. And there's competing uses people aren't willing to allow mangroves to grow back. So maybe there's a. Fishpond or big area. Fishponds in Indonesia. We have over a million hectares fishpond taking the place of mangroves. So they try to maybe pay lip service to mangrove restoration planting them out to see. There's no land use conflict. And they die and then they plant them again next year, and it becomes an annual kind of futile event. What's really needed is resolving the land use conflict and putting allowing mangroves to coexist with humans where they belong that was Ben Brown, mango expert. Thank you for your company from Benon. I good.
