Sustainable intensification of smallholder farming is a serious option for satisfying 2050 global cereal requirements and alleviating persistent poverty. That option seems far off for Sub-Sahara Africa (SSA) where technology-driven productivity growth has largely failed.
Climate change is a world wide phenomenon that has huge implications on economic, social and ecological challenges to the global community and to smallholder farmers especially in low income countries.
Climate change is one of the potent challenges facing smallholder farmers in sub-Saharan Africa in the recent past owing to the pattern and magnitude with which it presents the extreme events such as floods and drought.
Million tons of waste glass is being generated annually all over the world. Once the glass becomes a waste it is disposed as landfills, which is unsustainable as this does not decompose in the environment. Glass is principally composed of silica.
Cities can be seen as systems of organized complexity formed by interrelated and highly dynamic sub-systems. This paper reflects on the interactions and tensions between socio-ecological and/or socio-technical sub-systems in cities and their capacity to either improve or block urban processes.
When analyzing urban accessibility at a neighborhood scale, the pressure of parking is determinant to decide whether using a private car is an option for accessing local facilities or not. This paper intends to analyze the impact of different parking pressure characteristics in the estimation of local accessibility.
Rapid development and transformation are the main causes for declining urban natural landscapes as well as its physical and environmental qualities. Currently, rehabilitation and preservation actions cause tough pressures to cities, which lead to serious damages on urban natural landscapes.
Healthcare facilities throughout Europe are constantly changing to support efforts to provide efficient healthcare services with decreasing resources. Recent changes include larger and more specialist hospitals to achieve economies of scale. This approach has yet to be proven to sustainably respond to the demands, and efficiently satisfy the users’ needs.
physical form and pattern of built environment in a city is the outcome of prevalent planning and design standards and building regulations. Many common issues of built environment are the consequence of existing building regulations in that settlement as building regulations are borrowed from other cities and adopted from one place to another across the country.
