Eastern Africa

Restoration of degraded landscapes through the implementation of soil and water conservation practices is considered a viable option to increase agricultural production by enhancing ecosystems. However, in the humid Ethiopian highlands, little information is available on the impact of conservation practices despite wide scale implementation. The objective of this research was to document the effect of conservation practices on discharge and sediment concentration and load in watersheds that have different soil depths and topography.

Global Geo-Informatics Options by Context (GeOC) Flyer (English version).

Décembre, 2017

This is the english version of the flyer done for the workshop "Systems Tool-aided Participatory Development of Sustainable Land Management Scenarios: 2nd Workshop". This activity is under the output activity "User-friendly, interoperable online tool, containing country-specific, accessible knowledge base of standardized, geo-referenced SLM, to enable stakeholders to query SLM options in different context" of the GIZ funded project 'Impact evaluation of SLM options to achieve land degradation neutrality'.

Modeling smallholder farmers' preferences for soil management measures: a case study from South Ethiopia

Journal Articles & Books
Décembre, 2017
Ethiopia

Land degradation is a major environmental problem in Ethiopia posing serious threats to agricultural productivity and livelihoods. The interactions of numerous socio-economic, demographic, natural, and institutional factors constitute the underlying causes of soil degradation in Ethiopia. However, there exist evidence gaps on the contextual factors that hinder investments on soil conservation among smallholders.

Integrating Plant Science and Crop Modeling: Assessment of the Impact of Climate Change on Soybean and Maize Production

Journal Articles & Books
Décembre, 2017

Increasing global CO2 emissions have profound consequences for plant biology, not least because of direct influences on carbon gain. However, much remains uncertain regarding how our major crops will respond to a future high CO2 world. Crop model inter-comparison studies have identified large uncertainties and biases associated with climate change. The need to quantify uncertainty has drawn the fields of plant molecular physiology, crop breeding and biology, and climate change modeling closer together.

Restoring Degraded Rangelands in Jordan: Optimizing Mechanized Micro Water Harvesting using Rangeland Hydrology and Erosion Model (RHEM).

Jordan's rangelands, the so called Badia, home of the Bedouins, are threatened through a combination of over-exploitation of the ecosystem services and a changing climate towards drier seasons and highly erratic rainfalls. In the recent decades, the once productive grazing lands transformed into sparsely vegetated and crusted desert grounds not capable of retaining the sporadic rainwater within the landscape - and consequential surface runoff inevitably accelerates soil erosion and gullying.
