聯合國警告：旱災與沙漠化加劇，威脅糧源的穩定

Smtv 11/03/07
氣候變遷（climate change）與土質惡化造成世界各地更嚴重的乾旱，而且缺糧、缺水的情況更為嚴重，有時更引起紛爭與居民的遷徙。根據聯合國防治沙漠化公約（climate change Combat Desertification）執行秘書尼亞卡賈（Luc Gnacadja）表示，1950年以來將近20億公頃的土地惡化，每年損失的土地達1千2百萬公頃，而且全球暖化（global warming）使土地惡化更嚴重，這些變遷也造成氣候的變動以及農作收成減少，但目前人口對糧食需求更高，預計到2050年將增加70％的需求。而且全球44％的糧食是­在乾燥地區生產，當地的資源分配本來就較拮据，執行秘書尼亞卡賈表示：「乾燥地區是世上最易發生衝突的地區，這並不是偶然。當地的不穩定，正是因為民眾希望擁有肥沃農地、­水源等稀有資源。」尼日（Niger）、中國、印度等較易受災的國家近年來都大量植樹，積極進行多項抗沙漠化行動，尼亞卡賈先生警告各界應該更直接提供支援，幫助乾燥地區­居民維持糧源穩定，保護民眾家園。他也提到有一款新型的沙漠化監測系統正在施行當中，可以追蹤土質的惡化，並預先加以防範。

As climate change and land degradation are noted to cause increasing drought and aridity across the world, food and water shortages are also growing more severe, linked at times to both conflict and forced migration.

According to Executive Secretary of the UN Convention to Combat Desertification Luc Gnacadja, nearly 2 billion hectares of land has been degraded since 1950, with 12 million hectares being lost annually, which is now increasing with global warming. These changes in turn have caused weather shifts including reduced crop harvests at a time when rising food demands are estimated to require a 70% boost in food production by 2050.

Moreover, 44% of the world's food is produced in arid dryland regions where resource allocation is already an issue. Executive Secretary Gnacadja said, "The drylands are the most conflict-prone zone of the world, and that is not by accident. Instability is fuelled by precisely the quest of people to have access to very scarce resources like productive land and water."

While vulnerable countries such as Niger, China and India have in recent years been making valiant efforts to curb desertification through activities like large scale-tree plantings, Mr. Gnacadja warns that more direct support is necessary to help those living in the dryland areas maintain food supplies as well as their homes.

He also said that a new desertification monitoring system is being launched in an effort to track land degradation and try to protect against it. Our appreciation, Mr. Gnacadja, the UN Convention to Combat Desertification and all others working to raise awareness of our fragile planet's need for urgent care.

Let us join in more sustainable practices so that the Earth may be renewed to continue supporting the lives of all beings.
