Filling in the gaps | Reimagining underutilised city space to promote sustainable intensification
… outline the urgent need for alternative, more sustainable approaches to housing development. This thesis addresses these issues, by proposing an alternative approach to housing, focussing on the densification of underutilised spaces within urban areas through the concept of ‘finding space’. …

Sustainable Intensification of Agriculture: Opportunities and Challenges for Food Security and Agrarian Adaptation to Environmental Change in Bangladesh
… investigates three unique aspects of sustainable agricultural intensification (SAI) in the context of Bangladeshi rice production. The first article presents a qualitative analysis of SAI and farmer surveys in the embanked polder region of coastal Bangladesh. The second article …

Is sustainable intensification possible in smallholder crop production systems in semi-arid West Africa? The case of the Red Volta and Black Volta basins in Northern Ghana
Food systems experts consider Sustainable Intensification (SI) a key concept to tackle the increasing global and regional food demand, particularly in semi-arid West Africa, which is prone to socioeconomic and biophysical challenges. In Ghana, crop production varies across semi-arid systems, …

Diversity patterns and conservation priorities in the "Mountains of Central Asia" biodiversity hotspot
… the need for region-specific management. Sustainable intensification and control of non-native species may improve productivity in lowland croplands, while the heterogeneous structure of high-mountain croplands should be maintained to conserve their species-rich segetal flora. Integrating …

Discovery and characterization of genes controlling nitrogen utilization in maize
Maize (Zea mays, L.) yield has a well-documented response to supplemental nitrogen (N). As a result of this response, supplemental N is applied to nearly all maize grown in the U.S. and other industrialized nations, and the use of N fertilizer in developing countries is on the rise. While …
