When speaking from the magic South India, most people mean the picturesque landscape named Kerala Backwaters. The widely ramified network of lagoons, lakes and flat bottomlands is indeed a unique symbiosis between natural and cultural landscapes. While most of the bottomlands is used for rice fields, the lagoons and channels are natural highways for transfer between the rural villages and systematically connected channels to flood the rice fields when it's needet. But today, the Backwaters are urgently threatened by the globar warming. The slowly but steady raising sea level floods the land area and therefore shrinks the area for traditional living and agriculture. Added to this, more and more salt water comes into the backwaters and makes the water unuseable for the farm whetlands.
