Effects Climate Variability on Household Income Stability Among Smallholder Farmers in Rutsiro District of Western Province, Rwanda

这项在卢旺达鲁齐罗区(2024-2026年)开展的混合方法研究表明,气候变率(特别是降雨波动和干旱)显著削弱了297户小农户的家庭收入稳定性,解释了67.5%的收入不稳定现象,并使得气候智慧型农业和灌溉领域的紧急干预变得至关重要。

Carbon storage efficiency and permeability decay during microbubble and conventional carbon dioxide injection in high-permeability sandstone

虽然微气泡二氧化碳注入可以通过暂时阻断优势流通道,在低流速下增强高渗透性砂岩中的碳封存效率,但与常规注入相比,由于细粒物质迁移和累积地层损伤,它最终会导致更大的渗透率衰减和注入风险,尤其是在高流速情况下。
