This paper uses panel data of 42 sub-Saharan Africa countries from 2005 to 2015 to examine the effect of aid for trade (AfT) on export diversification. The average Hirschman-Herfindahl index measure of 0.77 indicates that the export basket of sub-Saharan African countries is very narrow. This is...

About fifty years after the independence of most former colonies on the African continent, books on African nationalism again rank high on the agenda of the international academic discussion. A selection of three recent publications demonstrates the advances made in scholarly analysis in the...

This study investigates the causal links among agricultural imports, agriculture productivity, and economic growth in 40 sub-Saharan African countries over the period 1990-2015. Granger causality tests are applied to infer direction of causality, and the generalized two-stage least squares...

Die deutsche Energiepolitik verfolgt zwei wesentliche Ziele, zum einen die Abkehr vom Atomstrom (Energiewende), zum anderen den Ausbau erneuerbarer Energien, um für das Klima gefährliche Treibhausgase einzusparen. Dabei kommen unterschiedliche Instrumente zum Einsatz, die sich teilweise...

Drylands in sub-Saharan Africa are strongly affected by the impacts of climate change. Temperature increases, changes in rainfall patterns, and land degradation pose serious threats to food security, health, and water availability in the region. The increase in livelihood insecurity can in turn...

Die Klimakonferenz in Kopenhagen im Dezember 2009 ist richtungweisend. Die G8-Länder haben sich grundsätzlich darauf verständigt, das Zwei- Grad-Ziel anzuerkennen. Viele Staaten haben wie Europa signalisiert, dass sie die Treibhausgasemissionen deutlich senken wollen. Der Erfolg von...

Agreement is developing among agricultural scientists on the emerging inability of agriculture to meet growing global food demands. Changes in trends of weather conditions projected by global climate models will challenge physiological limits of crops and exacerbate the global food challenge by...

The projected changes in planted area, yield per area, net exports/imports and prices for five major agricultural crops in South Africa were simulated using the projections of four Global Circulation Models (GCMs) under three socio-economic scenarios. The GCM projections show consistent strong...

Im Zuge des anstehenden weiteren Umbaus des Energiesystems in Deutschland wird es erforderlich werden, sukzessive weitere Flächen für die Windenergienutzung an Land bereitzustellen. Der derzeitige regulative Rahmen weist jedoch Defizite aus, welche die entsprechenden Planungen erheblich...
