就快將我哋打低
將現實變得越嚟越難搞
用技術去解決依啲問題
就係由人口增長引致嘅
大部份變緊做沙漠嘅土地
有大面積嘅荒地形成
有三分二嘅地方正荒漠化緊
同土壤裏面嘅有機物質有關
地球上乾旱同半乾旱嘅地方
睇下土壤嘅表面
先會發現得到
過度放牧而食晒啲植物
都同我一樣知道呢個常識
規劃成未來嘅國家公園
一個專家團隊嚟評估我嘅研究
最悲傷同做得最錯嘅事
全情投入去搵出解決方案
同非洲一樣咁大
就無其他解釋
揾到依啲相
而且威脅緊全球
日出時份會更加凍
去到超過世界一半嘅土地
點解依個現象會響一萬年前發生
依啲隨季節改變濕度嘅環境
同過度放牧有關
同群體狩獵嘅掠食動物有關
響佢哋嘅食物上面排便排尿
可以確保土壤有足夠植被
我哋傳統上會用火燒
亦會釋放出碳元素
超過十億公頃嘅草地
去畀啲植物復原
養咗小牛去測試土地負荷
枯枝落葉同埋護根
啲植物都可以自由生長
身為科學家嘅我哋無得揀
嚟應對氣候變化同荒漠化時
世界上最大嘅人造沙漠出現
比集結同埋放牧做得更多
都無遇到咁複雜嘅問題
可以滿足到我哋響生物學上嘅需求
同埋經濟嘅複雜難題
我哋可以任由佢哋俾猛獸弱肉強食
係同安排地方種嘢有關
而大幅增加
都響土壤表面蒸發咗
每樣嘅產量都比以前更加好
同其他動物一齊生活
始終被侵蝕超過 30 年
土地被侵蝕、貧瘠嘅地方
吸引大象等等嘅動物走過去
幫助南非卡魯沙漠一個家庭
一個家庭嘅第三代仲住響嗰度
就係你見到咁變緊沙漠
點樣因為人減少羊嘅數目而變差
拯救佢哋嘅家庭同文化嘅希望
我相信同石化燃料造成嘅一樣大
暴力、社會崩潰同戰爭
正喺度受苦、瀕臨死亡
實行依個計劃
可以清楚咁話畀你聽
到去工業革命前嘅水平
我哋需要提供食物畀啲牲畜
響好多年之前嘅津巴布韋
有更加多題材可以寫
ABOUT THE SPEAKER
Allan Savory - Grassland ecosystem pioneerAllan Savory works to promote holistic management in the grasslands of the world.
Why you should listen
Desertification of the world's grasslands, Allan Savory suggests, is the immediate cause of poverty, social breakdown, violence, cultural genocide -- and a significent contribution to climate change. In the 1960s, while working in Africa on the interrelated problems of increasing poverty and disappearing wildlife, Savory made a significant breakthrough in understanding the degradation and desertification of grassland ecosystems. After decades of study and collaboration, thousands of managers of land, livestock and wildlife on five continents today follow the methodology he calls "Holistic Management."
In 1992, Savory and his wife, Jody Butterfield, formed the Africa Centre for Holistic Management in Zimbabwe, a learning site for people all over Africa. In 2010, the Centre won the Buckminster Fuller Challenge for its work in reversing desertification. In that same year he and his wife, with others, founded the Savory Institute in Boulder, Colorado, to promote large-scale restoration of the world's grasslands.
