摘要

高粱是埃塞俄比亚粮食安全的重要作物。然而,这些高粱品种需要较长的生长期(6-8 个月),这使得作物很容易受到干旱的影响,包括降雨延迟、干旱和关键时期的干旱。根据降雨情况,陆稻通常在 3 月或 4 月播种,11 月左右收获,但往往会因干旱而歉收。在这种情况下,早熟改良品种是农民的一个选择,但如何获得这些改良品种的种子却是一个难题。与陆生品种不同,早熟改良品种大约在 7 月的前几周播种,11 月收获。正规的种子系统只能繁殖数量有限的改良高粱种子,小农高粱种植者很少能获得这些种子,大多是作为政府定向计划的一部分。因此,为解决小农户高粱种植者的种子短缺问题,我们引入了基于社区的种子繁殖计划(CBSM)。2015 年,旨在提高小农高粱种植者种子繁殖能力的试验取得成功后,该进程进一步通过 CBSM 计划在更大范围内实施。2016 年至 2017 年期间,在埃塞俄比亚西哈拉盖的三个地区成立了三个 CBSM 农民小组,共有 56 人参加。两个早熟耐旱改良高粱品种(Dekeba 和 Melkam)的种子在总面积 49.58 公顷的土地上繁殖,共获得 215.6 吨认证种子。研究结果表明,通过提供优质种子、扩大改良种子的使用范围、提高作物质量以及增强社区管理种子分配的能力,高粱改良种子管理计划提高了小农的高粱产量、收入和气候适应能力。与当地组织和政府机构的合作对于计划的成功至关重要,这使得该计划能够惠及不同地区的更多农民。事实证明,该计划对埃塞俄比亚干旱低地的小农高粱种植者来说是成功的,为其他地方面临的类似挑战提供了可借鉴的经验,并为小农推广了可持续的解决方案。

Empowering Smallholder Sorghum Farmers for Resilience: Lessons from a Community-Based Seed Multiplication Scheme in West Hararghe, Ethiopia
Sorghum is a vital crop for food security in Ethiopia. Sorghum landraces are particularly crucial in crop-livestock mixed farming, however, the extended growing periods (6-8 months) required for these landraces make the crop vulnerable to recurrent drought events associated with delayed rain, dry spells, and drought during critical stages. The landraces are usually planted in March or April depending on the onset of rainfall and harvested around November but often fail due to drought. In such situations, early-maturing improved varieties are an option for farmers but access to seeds of these improved varieties is a challenge. Unlike the landraces, the improved early maturing varieties are planted around the first weeks of July and harvested in November. The formal seed system multiplies only a limited amount of improved sorghum seed, which is rarely available to smallholder sorghum growers, mostly as part of a government package for targeted programs. Therefore, a community-based seed multiplication (CBSM) scheme was introduced to address seed shortages among smallholder sorghum farmers. After a successful experiment in 2015 aimed at enhancing seed multiplication by smallholder sorghum farmers, the process was further implemented on a larger scale using the CBSM scheme. Between 2016 and 2017, three CBSM farmer groups consisting of a total of 56 participants were established in three districts of West Hararghe, Ethiopia. Seeds of two early-maturing and drought-tolerant improved sorghum varieties (Dekeba and Melkam) were multiplied on a total area of 49.58 hectares, resulting in 215.6 tons of certified seeds. The study's findings indicate that the CBSM scheme enhanced smallholder farmers' sorghum yields, incomes, and climate resilience by providing high-quality seeds, expanding access to improved seeds, improving crop quality, and empowering communities to manage seed distribution. Partnerships with local organizations and government agencies were vital for success, allowing the scheme to reach more farmers in different regions. The scheme proved successful for smallholder sorghum growers in Ethiopia's dry lowlands, offering lessons applicable to similar challenges elsewhere, and promoting sustainable solutions for smallholder farmers.
