農(nóng)業(yè)是孟加拉國經(jīng)濟的主要支柱,農(nóng)業(yè)產(chǎn)值占國民生產(chǎn)總值的17%左右,并為該國約45%的勞動力創(chuàng)造就業(yè)機會,孟加拉國70%左右的人直接依靠農(nóng)業(yè)為生。這一部門在確保國家糧食安全、總體經(jīng)濟增長、消除貧困和實現(xiàn)工業(yè)化的經(jīng)濟結(jié)構(gòu)改革方面發(fā)揮著重要作用。人民的生活和整個經(jīng)濟的發(fā)展取決于農(nóng)業(yè)生產(chǎn)和農(nóng)業(yè)收入。孟加拉國近75%的人口住在農(nóng)村,其中大多數(shù)依靠農(nóng)業(yè)部門。孟加拉國普遍存在氣候風(fēng)險和自然災(zāi)害,使其成為世界上一個非常脆弱的國家。由于氣候變化,洪水、冰雹、干旱、降水變化和其他事件的嚴重程度和頻率的增加,降低了發(fā)展中國家農(nóng)民的生計能力。孟加拉國的農(nóng)業(yè)部門主要面臨大規(guī)模的洪水和颶風(fēng),這些災(zāi)害摧毀了整個經(jīng)濟和農(nóng)作物。農(nóng)業(yè)的迅速增長有助于減輕貧困,并為農(nóng)民提供生計。盡管農(nóng)業(yè)部門對孟加拉國的整體經(jīng)濟作出了巨大貢獻,但該國的農(nóng)業(yè)仍處于欠發(fā)達狀態(tài)。本文通過綜合考慮氣候變化對整個農(nóng)作物種植的影響,而不是關(guān)注某一特定作物的產(chǎn)量,從而更好地揭示了農(nóng)業(yè)部門對氣候變化的脆弱性。本研究既考慮了農(nóng)民的每公頃純收入,又考慮了農(nóng)業(yè)部門的耕地價值,同時也考慮了氣候變化影響下的收入和損失。該研究以孟加拉的蒂斯塔·米德平原、舊雅魯藏布江平...
