ダラットの第12区のなだらかな丘の向こうに、文字通り革命的なものが育っています。観光客が伝統的なイチゴ農園に集まる一方で、宇宙ステーションのように見える気候管理された温室で静かな農業革命が根付きつつあります。
ミン叔父さんに会いましょう。かつてはコーヒー農家だった彼は、アラビカ豆を捨てて無土壌のレタス畑を広げました。「みんな俺は狂ってるって言ったよ」と笑いながら、栄養豊富な水に浮かぶ完璧なバターヘッドレタスの列を指さします。「今では甥が農業工学を学んで、事業を拡大したいと言っているんだ」と。
これらの水耕レタス農場はダラットの農業のアイデンティティを変えつつあります。従来の農業より90％も少ない水で、わずか30日で収穫可能な葉物を生産し、ホーチミン市からハノイまでの高級レストランに供給しています。
クホーコミュニティはこの技術を受け入れ、伝統的な高原農業の知恵と最先端の水耕栽培を融合させています。多くの農場では**「未来農業ツアー」**を開催し、訪問者は日本の水菜、イタリアのルッコラ、レインボーチャードなど、ダラットの一年中完璧な気候で育つ聞いたことのないレタスの品種を見ることができます。
何が特別なの？ 都市部の垂直農場とは異なり、ダラットの高原の立地は自然な冷却効果があり、エネルギーコストを40％削減します。その結果、ベトナムで最も高価なレタスの一つ（1キロ80,000 VND）でありながら、最も新鮮なものとなっています。
dalat.appの訪問者はこれらの農業ツアーをますます予約しており、伝統的な花園とベトナムの農業の未来を垣間見る体験を組み合わせています。これはダラットが単に農業遺産を守っているだけでなく、それを革命的に変えている証拠です。
