Banana weevil (Cosmopolites sordidus) pseudostem damage, crop traits and management practices from East Africa Highland banana farms in the Mt Elgon region, Mbale District, Uganda (2021)@en

This dataset contains farm-level measurements of East African Highland Banana crop morphology, banana weevil (Cosmopolites sordidus) pseudostem damage, and associated management practices collected from banana farms in the Mt Elgon area of Mbale District, eastern Uganda, in 2021. Surveyed banana farms are located at elevations between 1700 and 2200 m above sea level. The dataset includes spatial attributes (such as village, district, latitude, longitude, altitude, and coordinate uncertainty) and biological variables, including pseudostem morphology (upper and lower inner and outer diameters) and pseudostem banana weevil damage (%) recorded separately for inner and outer tissues at both upper and lower stem sections. Management and household variables include the number of farm visits, the type of farm labour, manure application, pesticide use, other banana weevil management practices, intercropping status and type, slope type, farm age (years), farmer age (years), and farmer-reported preferred and least-preferred banana varieties with reasons for their rankings. Data were collected during on-farm field visits. Pseudostem diameters were measured directly on freshly cut pseudostems with the cross-section exposed, using a graduated measuring ruler. Pseudostem damage was assessed by cutting the pseudostem and visually estimating the proportion of tissue damaged by banana weevil larvae at each stem section. Management, socio-economic, and preference variables were obtained through structured farmer interviews conducted during the same visits. Farm locations were recorded at the village level and linked to geographic coordinates derived from open-source geospatial data, primarily OpenStreetMap. Coordinates represent village-level centroids and are reported in the World Geodetic System 1984 coordinate reference system. A coordinate uncertainty of 1 km was applied to village centroids to reflect spatial generalisation and protect participant confidentiality. Where villages could not be uniquely resolved, district-level reference coordinates were used with an expanded uncertainty of 5 km to reflect reduced spatial precision. The dataset is intended to support analysis of interactions between banana weevil pest damage and environmental conditions in a mountain ecosystem. It is also intended to document the distribution of East African Highland Banana crop varieties in Uganda's high-altitude production areas.本数据集收录了2021年从乌干达东部姆巴莱区埃尔贡山地区的香蕉农场采集的东非高地蕉（East African Highland Banana）植株形态、香蕉象甲（Cosmopolites sordidus）假茎危害情况及相关田间管理措施的农场级实测数据。本次调查的香蕉农场海拔介于1700米至2200米之间。 数据集涵盖空间属性数据与生物学变量：空间属性包括村落、行政区、纬度、经度、海拔及坐标不确定性；生物学变量则包括假茎形态指标（上下段茎秆的内外直径），以及分别针对上下茎段的内外组织、由香蕉象甲幼虫造成的假茎危害比例（%）。 管理与家庭社会经济变量涵盖农场探访次数、农场用工类型、有机肥施用情况、农药使用情况、其他香蕉象甲防控措施、间作模式与类型、坡地类型、农场经营年限（年）、农户年龄（年），以及农户自述的偏好与非偏好香蕉品种及其选择理由。 所有数据均通过田间实地探访采集获得：其中假茎直径的测量采用带刻度的直尺，直接在横切面暴露的新鲜切割假茎上完成；假茎危害程度则通过切割假茎后，目视估算各茎段内受香蕉象甲幼虫破坏的组织占比来评估；管理、社会经济及品种偏好相关数据通过同次探访期间开展的结构化农户访谈获取。 农场位置以村落为单位记录，并关联源自开源地理空间数据（主要为OpenStreetMap）的地理坐标。坐标为村落级质心，采用1984世界大地测量系统（World Geodetic System 1984）坐标系。为反映空间概化程度并保护受访者隐私，村落质心的坐标不确定性设定为1千米。若无法唯一确定村落位置，则采用区级参考坐标，其坐标不确定性扩大至5千米，以体现空间精度的下降。 本数据集旨在支持山地生态系统中香蕉象甲虫害危害与环境条件间相互作用的相关分析，同时也用于记录乌干达高海拔种植区东非高地蕉品种的分布情况。
