Abstract

ABSTRACT This study was carried out to assess crop diversity among smallholder farmers in Kogi State, Northern Nigeria. A multistage sampling technique was used to choose 302 crop farmers, and a well-structured questionnaire was used to generate the data. The information gathered was analysed using the Shannon and Simpson indices and the Poisson and Tobit regression models. The results show that crop production was dominated by male farmers on plots averaging 1.8 ha in size, with an average number of three crops grown per plot. The average values for the Shannon index and Simpson index are 0.34 and 0.85, respectively. The socio-economic factors explaining crop diversity in the area were the farmers’ age, level of education, household size, farm size and income. This study indicates policy strategies are needed that enhance technical knowledge and raise awareness of agro-crop biodiversity management. It also reveals a need for an increase in rural farm household incomes and greater investment in land reforms at both local and national levels in Nigeria. Key policy insights agro-crop diversity ecosystem environmental sustainability polyculture smallholders

尼日利亚北部科吉州小农户农作物生物多样性评估

摘要本研究旨在评估尼日利亚北部科吉州小农户的作物多样性。采用多阶段抽样技术选择302名种植户，并使用结构良好的问卷生成数据。使用Shannon和Simpson指数以及Poisson和Tobit回归模型对收集到的信息进行了分析。结果表明，在平均1.8公顷的地块上，作物生产由男性农民主导，平均每块地块种植三种作物。香农指数和辛普森指数的平均值分别为0.34和0.85。解释该地区作物多样性的社会经济因素是农民的年龄、教育水平、家庭规模、农场规模和收入。这项研究表明，需要制定政策战略，增强技术知识，提高对农作物生物多样性管理的认识。它还表明，尼日利亚需要增加农村农户收入，并在地方和国家层面加大对土地改革的投资。关键政策见解农作物多样性生态系统环境可持续性多种文化小农户

期刊介绍： The aim of Biodiversity is to raise an appreciation and deeper understanding of species, ecosystems and the interconnectedness of the living world and thereby avoid the mismanagement, misuse and destruction of biodiversity. The Journal publishes original research papers, review articles, news items, opinion pieces, experiences from the field and book reviews, as well as running regular feature sections. Articles are written for a broad readership including scientists, educators, policy makers, conservationists, science writers, naturalists and students. Biodiversity aims to provide an international forum on all matters concerning the integrity and wellness of ecosystems, including articles on the impact of climate change, conservation management, agriculture and other human influence on biodiversity.
