Abstract

Farmers' perception on soil erosion has not adequately reported in the conditions of Ghana though its causes and effects are time and site-specific. The objective of this study was to assess farmers' perception on soil erosion and implication for developing soil management strategy in the Eastern and Northern Regions of Ghana. A total of 130 household head farmers were interviewed and complemented with field observation and group. Data was analyzed using descriptive, chi-square test, T-test and binary logistic regression. The results show that there was significant variation in socioeconomic, farm and institutional attributes among the farmers`in the study regions. In the Eastern and Northern Regions, significantly higher proportions of the farmers (95.7% and 86.7%, respectively) perceived soil erosion as serious problem. Significantly higher proportions of the respondents (80%) perceived severe erosion problem at homestead land in the Eastern Region whereas severe erosion in the Northern Region was more noticed at distance farmlands (85.0%). In the two regions, the major causes of severe erosion as perceived by most farmers were over-cultivation, deforestation and heavy rainfall events. In the Eastern and Northern Regions, 58.6% and 75.0% of the farmers perceived, respectively, that soil erosion severity has been increased since the past 10-years. Perceptions of most frequently noted indicators of soil erosion were declined productivity, shallow soil depth, presence of rills, sheet erosion, soil loss from farmland, and change in soil color. Results of the binary logistic regression indicate that there is heterogeneity in the factors accounting for the perception of soil fertility. In developing promising soil management strategy in the study area, attention must be given to key socioeconomic, biophysical, farm and institutional factors.

摘要

尽管加纳的土壤侵蚀原因和影响具有时间和地点特异性,但有关农民对土壤侵蚀的感知情况在该国并未得到充分报道。本研究旨在评估加纳东部和北部地区农民对土壤侵蚀的感知及其对制定土壤管理策略的影响。共采访了 130 户农户,并辅以实地观察和小组讨论。使用描述性统计、卡方检验、T 检验和二元逻辑回归分析数据。结果表明,研究地区农民的社会经济、农场和制度属性存在显著差异。在东部和北部地区,分别有 95.7%和 86.7%的农民认为土壤侵蚀是一个严重的问题,这一比例明显较高。在东部地区,比例较高的受访者(80%)认为在自家土地上存在严重的侵蚀问题,而在北部地区,距离农田的严重侵蚀问题更为突出(85.0%)。在这两个地区,大多数农民认为导致严重侵蚀的主要原因是过度耕作、森林砍伐和强降雨事件。在东部和北部地区,分别有 58.6%和 75.0%的农民认为,自过去 10 年来,土壤侵蚀的严重程度有所增加。大多数农民认为土壤侵蚀的常见指标是生产力下降、土壤浅层化、出现沟壑、片状侵蚀、农田土壤流失和土壤颜色变化。二元逻辑回归的结果表明,造成土壤肥力感知差异的因素存在异质性。在制定有希望的土壤管理策略时,必须关注关键的社会经济、生物物理、农场和制度因素。
