The 2008 theme of the Day is Combating Land Degradation for Sustainable Agriculture. Country Parties, international and non-governmental organizations are invited to organize events to celebrate the World Day to Combat Desertification as an additional opportunity to increase awareness and participation in the implementation process.

Soil degradation
Degraded soils.
Soil degradation is a key global environmental indicator.
Very degraded soils are found especially in semi-arid areas (Sub-Saharan Africa, Chile), areas with high population pressure (China, Mexico, India) and regions undergoing deforestation (Indonesia).
Degraded soils reduce the possibilities for agriculture, increases the expansion of drylands/desert and hightens the risk for erosion.
This map presents the state of global soil degradation, from the GLASOD study in 1997.
Amazon Rain Forest Deforestation Crackdown
http://www.youtube.com/watch?v=QA-yprMOv7M&feature=share
CHAN:
Deforestation in Brazil's Amazon Rain Forest fell over 20 percent in June. The drop follows an intensified crackdown on illegal logging and cattle ranching.
STORY:
Deforestation of Brazil's Amazon Rain Forest fell over twenty percent in June. Environment Minister Carlos Minc says government pressure has been driving deforestation down.
[Carlos Minc, Brazilian Environment Minister]:
"I think deforestation rates are still very high and I think it's unacceptable, that is, we are not celebrating here. But anyhow, it is less worrisome that the negative trend began to decline precisely in the months when we expected numbers to rise."
Environmentalists are concerned that rising grain prices may lead farmers to expand their planted areas, pushing the agricultural frontier deeper into the forest.
The Environment Ministry said cattle ranching occupies as much as 80 percent of deforested Amazon areas, where an estimated 25 million heads of cattle are raised. Last month about 10,000 head of cattle were seized for illegal grazing.
Eleazar Volpato a forest engineering professor at the University of Brasilia, said the government must promote more preventive measures.
[Eleazar Volpato, Professor, University of Brasilia]:
"We can't wait to act only after deforestation has already occurred and we also can't depend only on the Police. We must use instruments that promote (sustainable) activities in the rain forest."
The government of President Luiz Inacio Lula da Silva has increased police raids on illegal logging and expanded protected areas while also building roads and hydroelectric plants in the region.
Conservationists fear some of these measures could increase deforestation in the long term.

Outro sismo no Japão... 11.4.2011
Um forte sismo de 6,6 na escala de Richter foi registado nesta segunda-feira no nordeste do Japão, perto da central nuclear de Fukushima, quando se assinala um mês da catástrofe que fez mais de 27 mil vítimas. O sismo, que ocorreu às 17h16 locais (9h16 em Lisboa), foi de magnitude 6,6, segundo o Instituto de geofísica norte-americano (USGS, an sigla inlgesa). O USGS actualizou a magnitude do sismo desta segunda-feira para 6,6, uma vez que as primeiras previsões apontavam para os 7,1 graus na escala de Richter. O alerta de tsunami foi lançado logo a seguir ao sismo mas entretanto já foi levantado. O epicentro do sismo foi em terra a 10 quilómetros de profundidade.

Sismo de magnitude 7,4 no nordeste do Japão - 7.4.2011
Um forte sismo abalou hoje o nordeste do Japão e as autoridades emitiram alerta de tsunami. Segundo o US Geological Survey, a magnitude foi de 7.4 na escala de Richter.
A Agência Meteorológica japonesa prevê que a onda venha a atingir os 2 metros de altura pelo que as autoridades estão a mandar evacuar as zonas costeiras ameaçadas, a mesma área já devastada pelo sismo e maremoto de 11 de Março.
O abalo foi registado às 23h34 locais (14h34 de Lisboa) e o epicentro localizou-se a 40 quilómetros de profundidade, no mar, defronte da província de Miyagi, a mais afetada pelo terramoto de Março.
Na sequência do sismo de hoje, os prédios em Tóquio abanaram cerca de um minuto.
