摘要

本系统性综述采用 PRISMA 协议,旨在确定气候变化对作物生产和粮食安全、水资源和畜牧业的已观察到和预计的影响,并探讨非洲各国为应对这一挑战而采用的适应战略的前景。通过审查,可以在一个方案中直观地看到当前气候对非洲各国农业和战略影响的最新各种结果。它使农业界和政策制定者在应对气候变化对农业、畜牧业、水资源以及粮食安全的风险时能够考虑到这一点。从所选 125 篇文章中得出的总体结果表明,在过去四年中,一些国家,尤其是北非、中非和南部非洲国家,缺乏对气候变化相关农业问题分析的研究。在这些地区,对牲畜、水和管理技术影响分析的研究也很有限。尽管农业部门受到气候变化的严重影响,但根据种植产品和地区的不同,其影响仍可能是积极或消极的。已实施的各种适应战略在综合应用时似乎比单一应用更有效。然而,在采用这些策略时也存在一些挑战,包括缺乏知识、获得投入的途径有限、设备不足以及资金限制。由于气候变化是一个持续存在且随着时间推移不断恶化的事实,目前实施的适应战略可能需要进一步改进。因此,我们的研究表明,应在这一领域开展更多研究,以促进不断改进。妇女的领导力对于采用可持续适应战略非常重要。建议在评估气候变化适应战略和粮食安全内容的有效性时引入性别因素。此外,应开展认真的研究,根据各地区重要的主食作物来确定最具影响力的适应战略,以应对气候变化对非洲粮食系统的影响。

A systematic review of recent estimations of climate change impact on agriculture and adaptation strategies perspectives in Africa

A systematic review of recent estimations of climate change impact on agriculture and adaptation strategies perspectives in Africa

The systematic review using the PRISMA protocol aims to identify the observed and projected impacts of climate change on crop production and food security, water resources, and livestock and explores the perspectives of adaptation strategies employed to cope with this challenge across African countries. The review permits visualization in one scheme of the most recent various results of ongoing climate impact on agriculture and strategies across African countries. It enables the agricultural community and policymakers to consider it as they address climate change risks to agriculture, livestock, water resources, as well as food security. Overall results from 125 selected articles show that in the last four years, there has been a lack of research on climate change-related issues analysis in agriculture in some countries, especially in Northern Africa, Middle Africa, and Southern Africa. In the same regions, studies on the impact analysis on livestock, water, and management techniques are limited. Even though the agriculture sector is severely impacted by climate change, the effects can still be positive or negative depending on the products cultivated and the region. The various adaptation strategies implemented seem to be more effective when applied as a combination than a single application. However, some challenges including the lack of knowledge, limited input access, insufficient equipment, and financial constraints in strategy adoption exist. As climate change is a persisting and continuing fact getting worse over time, the adaptation strategies implemented today may require further improvement. Thus, our study suggests that more research should be done in this area to facilitate continuous improvement. Women’s leadership is important in the adoption of sustainable adaptation strategies. The introduction of gender factors in the assessment of the effectiveness of climate change adaptation strategies and food security components is recommended. Also, serious research should be carried out to define the most impactful adaptation strategies according to the important staple growing crops by region to cope with climate change impacts in the African food system.

期刊介绍: The Earth''s biosphere is being transformed by various anthropogenic activities. Mitigation and Adaptation Strategies for Global Change addresses a wide range of environment, economic and energy topics and timely issues including global climate change, stratospheric ozone depletion, acid deposition, eutrophication of terrestrial and aquatic ecosystems, species extinction and loss of biological diversity, deforestation and forest degradation, desertification, soil resource degradation, land-use change, sea level rise, destruction of coastal zones, depletion of fresh water and marine fisheries, loss of wetlands and riparian zones and hazardous waste management. Response options to mitigate these threats or to adapt to changing environs are needed to ensure a sustainable biosphere for all forms of life. To that end, Mitigation and Adaptation Strategies for Global Change provides a forum to encourage the conceptualization, critical examination and debate regarding response options. The aim of this journal is to provide a forum to review, analyze and stimulate the development, testing and implementation of mitigation and adaptation strategies at regional, national and global scales. One of the primary goals of this journal is to contribute to real-time policy analysis and development as national and international policies and agreements are discussed and promulgated.
