Landsat Research Reveals a Change in Mangrove Trends

In this lesson: Link the observation period to mechanisms of recovery.

Read the story

A November 13 NASA feature describes research using satellite images from 1984 to 2023. Global mangrove losses gave way to expansion around 2010.

The gains came from colonising new ground and recovering damaged forests, although losses continued in some regions.

Read and practise

1. What period do the satellite images cover?

   1. 1984 to 2023
   2. Only November 13
   3. 2010 to 2027

2. Which pair explains the gains?

   1. New ground and loss of every old forest
   2. Recovery and the end of all regional losses
   3. New ground and recovery of damaged forests

Your turn

Explain how the trend changed and why that does not mean losses ended everywhere.
