摘要

小农的生计遵循与天气、作物和动物生产以及市场波动的年度周期相关的可预测周期性模式。了解季节性是了解农业系统行为和绩效的重要组成部分,尤其是在马里南部等季节性较强的地区。农民根据不同的时间跨度做出战略、战术和经营决策,以支持其农业活动。农户的不同资源禀赋影响着他们的决策和适应能力。本研究旨在了解农民应对天气多变性及相关后果的管理决策。我们采用案例研究方法,利用连续三年(2017-2019 年)收集的数据分析农业系统各组成部分之间的时间互动。我们重点研究了三个问题。首先,农民如何把握降雨、价格、粮食和饲料供应以及收入的季节性变化的规律?其次,季节性如何影响农场各组成部分之间的互补性,以及稀缺资源分配所导致的农业目标之间的权衡和协同作用?最后,不同资源禀赋的农户如何应对意外变化,这对上述协同作用和权衡有何影响?数据收集方法包括:(1)焦点小组讨论;(2)家庭调查;(3)详细的农场监测。农民开展了多种生产活动,这有助于减轻作物歉收的负面影响。这种多样性在为提高适应能力提供机会的同时,也造成了农业系统各组成部分之间的相互依存关系,从而导致丰年时的积极结果得到加强,而歉年时的消极结果得到削弱。这把双刃剑挑战了多样化能提高农业系统稳定性的简单假设。所有类型的农场都面临季节性资源限制,以适应意外变化。然而,与资源禀赋高的农户相比,资源禀赋中等的农户在目标间的协同作用和权衡方面的变化幅度较小,因为他们的人口和畜群与土地的比例更为均衡。我们的研究结果表明,更好地理解农场管理决策和季节性的影响是支持农场生产力和提高小农适应能力的关键。我们建议,旨在支持农场生产力的政策应关注不同资源禀赋的农场在适应变化时所面临的具体障碍。特别是,获得信贷不仅能帮助贫困农户克服季节性粮食和现金限制,还能帮助他们摆脱贫困陷阱。

Navigating seasonality in cotton-based farming systems in southern Mali

Smallholder farmers’ livelihoods follow predictable and cyclical patterns related to annual cycles of weather, crop and animal production and market fluctuations. Understanding seasonality forms an essential part of unravelling farming systems behaviour and performance, especially in contexts with strong seasonality, such as southern Mali. Farmers make strategic, tactical and operational decisions related to different time horizons to support their agricultural activities. The diverse resource endowments of farming households influence their decisions, and adaptive capacity. This study aimed to understand farmers’ management decisions to cope with weather variability and related consequences. We used a case study approach to analyse temporal interactions between farming system components using data collected over three consecutive years (2017–2019). We focused on three research questions. First, how do farmers navigate the regular patterns of seasonal variations in rainfall, prices, food and fodder availability, and income? Second, how does seasonality influence complementarity between farm components, and trade-offs and synergies among farming objectives that result from the allocation of scarce resources? Finally, how do farming households of different resource endowments respond to unexpected changes and how does this affect the above-mentioned synergies and trade-offs? The data collection methods included (1) focus group discussions, (2) household surveys, and (3) detailed farm monitoring. Farmers undertook diverse production activities, which helped to mitigate negative consequences of crop failure. While providing opportunities for increased adaptive capacity, this diversity also creates interdependencies among farming system components, leading to reinforced positive outcomes in good years and negative outcomes in bad years. This double-edged sword challenges the simple assumption that diversification increases the stability of a farming system. All farm types faced seasonal resource constraints to adapt to unexpected changes. However, the magnitudes of changes in synergies and trade-offs among objectives were less pronounced for medium resource endowed farmers because of their more balanced people- and herd-to-land ratio compared to high resource endowed farmers. Our findings suggest that a better understanding of farm management decisions and the influence of seasonality is key to support farm productivity and to expand the adaptive capacity of smallholders. We suggest that policies aiming to support farm productivity should pay attention to the specific impediments faced by farms with different resource endowments to adapt to changes. Especially, access to credit helps poorer farmers not only to navigate the seasonal food and cash constraints but also to escape poverty traps.

期刊介绍: Climate Risk Management publishes original scientific contributions, state-of-the-art reviews and reports of practical experience on the use of knowledge and information regarding the consequences of climate variability and climate change in decision and policy making on climate change responses from the near- to long-term. The concept of climate risk management refers to activities and methods that are used by individuals, organizations, and institutions to facilitate climate-resilient decision-making. Its objective is to promote sustainable development by maximizing the beneficial impacts of climate change responses and minimizing negative impacts across the full spectrum of geographies and sectors that are potentially affected by the changing climate.
