Effect of land use and cover change on carbon stock and water quality of River Atari in Kapchorwa-Uganda

Abstract: 
The objective of this study was to examine the trend in landuse/ cover change around Atari micro-catchment and determine the effect of these changes on carbon stock and Atari river water quality. An Earth Resources Data Analysis System (ERDAS) Imagine image processor was used for the digital analysis of Landsat image series (1973, 1996 and 2005) for deriving the land use/cover characteristics of the catchment. Preliminary results showed that subsistence farming has increased over time while grassland and forest have declined. Total suspended solids and total N in total organic carbon followed the same trend.
L’objectif de cette étude était d’examiner la tendance dans le changement d’utilisation de terre /couverture végétale autour du micro-basin d’Atari et de déterminer l’effet de ces changements sur le stock de carbone et la qualité d’eau de la rivière Atari. Un système d’analyse des données de ressources terrestres (ERDAS) a été employé pour l’analyse numérique de la série d’images de Landsat (1973, 1996 et 2005) pour conclure sur les caractéristiques d’utilisation de terre/couverture végétale du micro-basin. Les résultats préliminaires ont prouvé que l’agriculture de subsistance a augmenté au cours du temps tandis que les espaces de prairie et de forêt ont diminué. Les solides totaux suspendus et l’azote total dans le carbone organique total ont suivi la même tendance.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Natural Resource Management"
