CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Effects of Prosopis juliflora Invasions on land use/cover change in South Afar region, Northeast Ethiopia

Prosopis juliflora(henceforth referred as Prosopis) plant is an invasive species affecting the health of rangelands in Afar region of Ethiopia. The study aims to assess (1) the effects of Prosopisinvasion on land use land cover (henceforth referred to LULC), and (2) extent of vegetation cover changes. We used a combination of remote sensing data and field observations to analyze the effects Prosopisinvasion on land use/ land cover dynamics and changes (LULCC) for the patterns and dynamics of land-use/cover changes for 31 years from 1986 to2017 in the arid and semi-arid of Sothern Afar rangelands, Ethiopia. The overall accuracy for 1986, 2000, and 2017 were 81.4%, 82.3%, and 84.9% with Kappa statistics of 0.77, 0.79, and 0.82 respectively. InAmibara district, farmlands, water bodies, land under Prosopis, and grassland areas were increased during 1986-2017 by 1879 ha (10.8%), 1197 ha (55.6%), 3132 ha (99.0 %), and 31,039 ha (22.0 %), respectively. However, bare lands and woodlands areas were decreased by 1239 ha (56.7 %) and 36,065 ha (49.9 %), respectively. In Awash Fentale district, changes in land use/land cover types showed positive trends for farmlands, water bodies, Prosopis, and grazing lands by 4258 ha (81.4 %), 1035 ha (97.4 %), 2335 ha (97.0 %), and 18,187 ha (25.8 %) respectively in the same period. However, bare lands and woodland areas decreased by 59.78 ha (59.8 %) and 51 ha (50.9 %), respectively. If the present change continues, pastoralists grazing lands will be lost.
