World Migraotry Bird Day 2011 |
The 2011 theme for World Migratory Bird Day was "Land use changes from a bird's-eye view". The human use of land has a direct impact on migratory bird populations, which are particularly sensitive to any interference to the sites they use throughout their migratory cycle. Many aspects of human land use are extremely damaging to the birds' habitats. For example, urbanization and intensive agriculture can fragment and replace complex networks of habitats needed by the birds. Deforestation and mineral extraction can damage entire regions used along the birds' annual migration paths.
In addition, land reclamation and biofuel production remove or degrade crucial wetlands and other habitats for many migratory bird species.While human survival depends on these transformations of natural areas, a sustainable use of land is vital to reduce the impacts on our natural resources, such as water, soil, nutrients, plants and animals – including migratory birds.
