Biodiversity is threatened globally by human-mediated alteration of natural environment. This includes East African wetland ecosystems that are subject to agriculture expansion and intensification. Monitoring of biodiversity is crucial to understand and mitigate biodiversity losses. Beetles, while rarely studied, are potentially useful bioindicators due to their sensitivity to environmental changes. Our study aimed at investig...
Purpose Overcoming the limitations of synthetic vascular grafts in the development of biocompatible and regenerative vessels remains a long-term objective in tissue engineering. In this study, we engineered large-diameter fibrin-based vascular grafts with a target inner diameter of 21 mm replicating all three layers of the native human vessel wall in vitro. Methods The Tunica media was reconstructed using a compressed high-den...
Recovery dynamics of wetland vegetation along a hydrological gradient in an agriculturally used inland valley in UgandaNARA Subscribed
Wetlands in East Africa are important for providing ecosystem services and for conserving biodiversity. They are also suitable and increasingly used for agriculture. Between cropping cycles, spontaneous vegetation regrows on fallow plots. We hypothesize that recovery is affected by hydro-edaphic conditions and the duration of the fallow period. Land use intensification reduces fallow durations. A multi-year field study investi...
Potential Improvements in Crop Production in Egypt and Implications for Future Water and Land DemandNARA Subscribed
Similar to numerous water- and data-scarce regions, Egypt confronts a critical challenge in sustaining food production for its rapidly growing population. Consequently, the country’s water and land resources are under considerable stress and require careful management. About half of Egypt’s both annually harvested areas and renewable freshwater are allocated for cultivating rice, maize, wheat, and berseem clover. However, the...
Alternate wetting and drying: a water-saving technology for sustainable rice production in Burkina Faso?NARA Subscribed
With emerging water scarcity and rising fertilizer prices, optimising future water use while maintaining yield and nutrient efficiency in irrigated rice is crucial. Alternate wetting and moderate soil drying irrigation (i.e., re-irrigation when the water level reaches 15 cm below the soil surface) has proven to be an efficient water-saving technology in semi-arid zones of West Africa, reducing water inputs without yield penalt...
Subsequent primary neoplasms after childhood cancer therapy – design and description of the German nested case–control study STATT-SCARNARA Subscribed
Background Subsequent primary neoplasms (SPN) are among the most severe late effects and the second most frequent cause of death in childhood cancer patients. In this paper we introduce method and properties of the STATT-SCAR study (Second Tumor After Tumor Therapy, Second Cancer After Radiotherapy), which is a joint nested matched case–control study to evaluate the impact of chemotherapy (STATT) as well as radiotherapy (SCAR)...
Reconciling East-African Wetland Conservation with Human Needs: Managing Uncertainties in Environmental Policy DesignNARA Subscribed
Rapidly developing societies in East-Africa impose increasing pressures on wetlands due to rising food demand and degradation of upland soils. Reconciling wetland conservation with human needs for food and energy is therefore becoming an increasing contentious issue. Stakeholders and actor coalitions generate and apply a great variety of meanings, values, and interests when interacting with wetlands which are hardly predictabl...
Action on Invasive Species: Control Strategies of Parthenium hysterophorus L. on Smallholder Farms in KenyaNARA Subscribed
Parthenium hysterophorus L. (Asteraceae) is an invasive alien weed with detrimental effects on agricultural production, biodiversity, human and animal health, threating rural livelihoods in Asia and Africa. The problem emerged recently in the Kenyan Rift Valley, where it began to affect the landholdings of both agro-pastoralists and crop farmers. These vulnerable smallholders depend heavily on natural resources for their livel...
