Past global efforts at dealing with the problem of global warming concentrated on mitigation, with the aim of reducing and possibly stabilizing greenhouse gas (GHG) concentrations in the atmosphere. With the slow progress in achieving this, adaptation was viewed as a viable option to reduce the vulnerability to the anticipated negative impacts of global warming.
Smallholder livestock keepers represent almost 20% of the world population and steward most of the agricultural land in the tropics. Observed and expected increases in future demand for livestock products in developing countries provide unique opportunities for improving livelihoods and linked to that, improving stewardship of the environment.
Our study links environmental impacts of climate change to major socio-economic and agricultural developments in North Africa. We jointly investigate climate projections, vulnerability, impacts, and options for adaptation. Precipitation in North Africa is likely to decrease between 10 and 20%, while temperatures are likely to rise between 2 and 3 ◦C by 2050.
Soil fertility decline has become a major concern of policy makers worldwide. While many researchers assume that the problem is universal, others question the assumptions, evidence, methodologies and scale upon which beliefs of soil decline are based.
African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist.
The high incidence of disease is one of the major constraints to smallholder poultry production systems in Africa. In order to control various poultry diseases, ethnoveterinary medicine is widely practised by poor village farmers. Natural products, especially those which are locally available, are generally used.
In this essay, we attempted to catalogue and describe African indigenous knowledge, in contributing to sustainable health development in Sub Saharan Africa. In the face of poverty and threats of diseases such as ebola.We also describe how biotechnology can enhance cultural mechanism for improved health care.
Cultures all over the world have evolved illness representations that can accommodate not only new diseases, but also new epistemologies for explaining disease. This paper examines illness representations in Sub-Saharan Africa, and how these have responded to the emergence of AIDS.
Sub-Saharan Africa is facing a crisis in human health resources due to a critical shortage of health workers. The shortage is compounded by a high burden of infectious diseases; emigration of trained professionals; difficult working conditions and low motivation.
