Changing food waste regimes in Africa’s transition to export-oriented production: the case of Tanzanian avocado
"African nations are increasingly focusing on exporting high-value crops. However, a major challenge exists: high rates of food waste within supply chains. The problem is often seen as a technological issue—a lack of proper infrastructure and coordination creates inefficiencies. This research takes a different perspective, focusing on social relations within the supply chain. It uses the concept of “food waste regimes” to understand the underlying structures, relationships, and systems that
Accessible drone image processing for sustainable resource management of 3D tree-like crops using unsupervised algorithms
This study presents a novel AI-driven solution designed to enhance sustainable resource management and increase accessibility for farmers through visualized and digitalized tree information. The proposed methodology includes optimizing drone mapping for effective data coverage, capturing high-resolution imagery, and generating a 3D Point Cloud, with a particular emphasis on the integration of Weighted K-means, Density-based spatial clustering of applications with noise (DBSCAN), and cluster separation
Avocado Production and Local Trade in the Southern Highlands of Tanzania: A Case of an Emerging Trade Commodity from Horticulture
Avocado crop in Tanzania is sparingly investigated regardless of being an important fruit commodity. This study was undertaken to explore the yield and the value chain of this crop in the country. Data were collected mainly by face-to-face interviews with 275 avocado farmers, 231 avocado traders and 16 key informants. Descriptive statistics, Chi-square test and one-way analysis of variance were used for data analysis. The average crop yield ranged from 76 to 124 kg plant between regions. The average
