In the Nuba Mountains, Central Sudan, the recent end of a long-lasting civil war initiated large-scale transformation processes that, among others, affected the traditional agro-ecosystems of this formerly isolated region. Nuba farmers mainly rely on two farming plot types, the ‘far farm’ for sorghum cultivation and the ‘house farm’ or homegarden, called ‘jubraka’, for mixed cultivation of vegetables and fruit trees. Despite their importance for farmers’ livelihoods and conservation of local agrobiodiversity, jubrakas have been largely neglected by scientists. Unconfirmed recent reports indicate a rapid transformation of traditional jubrakas, often into commercial vegetable gardens that are characterized by high levels of external inputs such as mineral fertilizers. The particular structure of jubrakas as highly diverse agroforests and the actual situation in the Nuba Mountains provide a unique opportunity to use jubrakas as model systems for studying modernization dynamics of (sub)tropical agroecosystems. Main objective of the planned investigation is to determine the processes and consequences of jubraka transformation. In 60 jubrakas, including ‘traditional’ and ‘transformed’ (commercialized) ones, plant species diversity, nutrient fluxes, and management will be quantitatively assessed, combining agronomical, morphological, and molecular approaches. Multivariate statistical analysis will be used to determine the relative importance of drivers of transformation processes on plant species diversity and on food security of the local population.

在苏丹中部的努巴山区，长期内战最近结束，引发了大规模的转变进程，除其他外，影响到这个以前孤立地区的传统农业生态系统。努巴农民主要依靠两种耕作方式，一种是种植高粱的“远地农场”，另一种是混合种植蔬菜和果树的“家庭农场”或家庭菜园，称为“jubraka”。尽管jubrakas对农民的生计和保护当地农业生物多样性很重要，但科学家们在很大程度上忽视了它。最近未经证实的报告表明，传统的jubrakas正在迅速转变，往往变成商业菜园，其特点是大量使用矿物肥料等外部投入。朱布拉卡作为高度多样化的农林业的特殊结构和努巴山区的实际情况提供了一个独特的机会，使用朱布拉卡作为模型系统研究现代化动态（亚）热带农业生态系统。计划调查的主要目标是确定朱布拉卡转型的过程和后果。在60 jubrakas，包括“传统的”和“转化”（商业化）的，植物物种多样性，养分通量和管理将进行定量评估，结合农艺学，形态学和分子方法。将使用多变量统计分析来确定转化过程的驱动因素对植物物种多样性和当地人口粮食安全的相对重要性。
