英文摘要	Soil erosion coupled with high runoff poses a significant threat to the topsoil fertility, declining its productivity and raising major environmental and socio-economic issues such as land degradation, desertification, food scarcity, and hunger globally. Several conservation methods have been widely adopted in order to reduce runoff and protect the soil from erosion. The effectiveness of such conservation practices are controlled by many factors (i.e., climate, topography, soil properties, land use). To understand their efficiency and their trade-off, we conducted a meta-analysis by collecting 98 research articles within the time frame of 1981-2021, considering the most widespread soil and water conservation practices all over the world. The results exhibited that most of the conservation practices are useful in controlling soil erosion as compared to the runoff rate in which Hedgerow practice was found to be the most effective measure in controlling runoff rate (57 degrees Ao) while no-tillage was proved to be the most efficient in reducing soil erosion (83 degrees Ao). On the other hand, strip cropping showed a balanced runoff reduction efficiency (RRE) and soil erosion reduction efficiency (SERE), both reaching around 65 degrees Ao, followed by hedgerow (59 degrees Ao and 52 degrees Ao) and mulching (51 degrees Ao and 60 degrees Ao). The results were restrained by varying climatic and physical scenarios. This study provides a systematic overview of the effectiveness of different runoff and soil erosion conservation practices and their controlling factors in a holistic way that can serve as the basis for the government and policymakers for the sustainable and rational implementation of such practices in the future.
