The population of Guangaje, Ecuador is highly vulnerable to cyclical shifts in agricultural production. Current planting and harvesting cycles indicate the likelihood of close to 10 months of food insecurity and increased climatic variability has exacerbated food security issues by extending already existing periods of seasonal hunger. This degree of food vulnerability may help explain the population’s poor nutritional outcomes and lack of dietary diversity. Declining agricultural production has resulted in increased migration as households try to cover expenses. Although temporary migration enables families to meet immediate consumption needs, it shrinks on-farm labor capacity, which may negatively impact future harvests and reduce the quantity and diversity of household food consumption. Greater crop diversity, water retention and irrigation systems, and climate-adapted crops have the potential to decrease the impact of seasonality and increased climate variability on food and livelihood security. However, more research is needed to better understand the best approach and potential implications of these strategies.

季节性和气候变化对厄瓜多尔安第斯山脉生计安全的影响

厄瓜多尔瓜纳杰的人口极易受到农业生产周期性变化的影响。当前的播种和收获周期表明,可能出现近10个月的粮食不安全状况,气候变化加剧,通过延长已经存在的季节性饥饿时期,加剧了粮食安全问题。这种程度的食物脆弱性可能有助于解释人口的营养不良状况和饮食多样性的不足。随着家庭试图负担开支,农业生产下降导致移民增加。尽管临时移徙使家庭能够满足即时的消费需求,但它会减少农场的劳动能力,这可能对未来的收成产生不利影响,并减少家庭粮食消费的数量和多样性。更大的作物多样性,保水和灌溉系统以及适应气候变化的作物有可能减少季节性变化和气候变化对粮食和生计安全的影响。但是,需要进行更多的研究才能更好地理解这些策略的最佳方法和潜在含义。
