Herbal medicine has been used alongside modern medicine and many continue to rely on it for their health care despite the increasing use of modern medicine in Ghana. Herbal medicine has played a significant role in health care delivery, since time memorial.
The challenge of producing food for a rapidly increasing population in semi-arid agro-ecosystems in Southern Africa is daunting. More food necessarily means more consumptive use of so-called green water flow (vapour flow sustaining crop growth). Every increase in food production upstream in a watershed will impact on water user and using systems downstream.
Farmers’ local knowledge of soil fertility and management strategies plays a significant role in fertility maintenance of farmlands and also contributes to the participatory development of interventions to sustain farm productivity.
Ethnopedology, a hybrid discipline nurtured by natural as well as social sciences, encompasses the soil and land knowledge systems of rural populations, from the most traditional to the modern. Using this statement as a starting point, the first part of the paper defines ethnopedology in terms of conceptual scope, methodological approaches and dominant research themes.
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.
