安食,護境:重思印度之稻作
2026-05-23 · via Business News Today: Latest Business News, Finance News

青革命,化印地之食安。稻麦之植,为价稳、乡民生计之枢。政策持恒,印地今为世稻产之最,几占全球稻产之廿八,亦稻出口之魁,得全球之卅八。然此功亦负渐增之生态之费。

虽稻米之产逾亿五千万吨,然稻田之耕,犹为最耗水之农事,每公斤稻米需水千五百至二千五百公升。其弊尤显于西北印度恒河平原,地水日竭。于旁遮普,水层岁降四十三公分,有区竟至五十九公分。若此势不止,专家诫曰,州之部分恐二十五年内见沙化。

是时也,甲烷(CH4)之排放,其增暖之效几倍于炭酸(CO2),骤增矣。稻作之业,于2020年发甲烷三十二万公吨,占印度农事甲烷之发者什三。西北印度亦过用氮素肥料之热地,益甚土之敝与污染。

宏经之政,气候之治,其势所迫也。

此压力凸显重思印度水-能-食之关联之必要。耗水作物迅速耗竭地下之水,而廉价电力之补贴则助长过度灌溉。与此同时,采购与补贴政策偏袒稻麦,使农人囿于谷物之耕,损及土质、作物之异、饮食之丰。故可持续稻作非独农艺之挑战,实乃宏观经纬与气候治理之要务也。

再生水稻之术,可保丰产而节水土,减耗自然之资。广植高值作物,更增其韧性与土健。诸法既验,如交湿交干法(AWD)、旱直播稻(DSR)、短期稻种、精施养料、精量灌溉诸术,可大省水用,减温室气体之发。AWD与DSR独用,可减灌需之半至八成,减甲烷之发三至七成。

PM-PRANAM之制

要者,减稻作之排放,直促印度之气候之约,包括其至二零七零年净零之标,减排强度之目,及国度自主贡献(NDCs)下长远碳汇之旨。印度之政策之域,渐显此急切。如主仆民农耕水利计划(PMKSY),倡节用水利;而土健康卡之制,使施肥更智。其间,主仆民母地修复、觉知、滋养、改良之计划(PM-PRANAM),鼓励向再生农耕、多元作物之系转变,根植于土著之识。补此诸力,诸举示无烧之制、节水之耕、农人参与,可成规模之效。此诸举已助避数千万吨CO2e之排,省近十亿升之水,因再生农耕之术。其广志,欲以农人赋权、本土农企、政策支持、战略合作为径,建再生之食域。

可持續稻米之勢與基石已具。今之難,在於調和誘因、採購與資源管理,以合長遠可持續之目標——增農場之收穫與生產力,同時復生生態之平衡。印度之次 agricultural transformation,非僅以產量計,亦以可持續之生長度量之。
