Kenya’s charcoal sector is worth billions of dollars in market value and is one of the most important sources of energy in urban and rural areas. This study sought to create greater understanding about the charcoal value chain to understand its structure, function and actors and their roles. The study was carried out through a questionnaire survey...

Biomass fuels remain a very important energy source for millions of Kenyans, consistently meeting close to 70% of domestic energy requirements over the decades. The charcoal sub-sector is one of the most important sources of employment and is reported to be a major source of livelihood for about 0.64 million people, with a market value worth billio...

“People and Power: Stories of Small Scale Renewable Energy Entrepreneurs in Kenya” documents 11 renewable energy projects to highlight how Decentralised Renewable Energy is empowering people across the country, and especially in rural areas which rely heavily on biomass energy sources due to the lack of grid connections. The 11 case studies of rene...

Charcoal is an important urban fuel, however, when production is unregulated it is a major cause of land and forest degradation. Production through selective harvesting of the preferred large, hardwood tree species leads to a degraded residual forest or woodland comprised of juvenile hardwood trees and unused softwood tree species. This situation c...

Agroforestry systems in Sub-Saharan African drylands are complex and heterogeneous in nature even under similar biophysical conditions. This can be attributed to household needs and socioeconomic status which influence the species and utility of the adopted trees. This has an impact on the trees establishment and management system through planting...

The production of charcoal is an important socio-economic activity in sub-Saharan Africa (SSA). Charcoal production is one of the leading drivers of rural land-use changes in SSA, although the intensity of impacts on the multi-functionality of landscapes varies considerably. Within a given landscape, charcoal production is closely interconnected to...

Tropical dry forests and woodlands are comprised of trees that are specially adapted to the harsh climatic and edaphic conditions, providing important ecosystem services for communities in an environment where other types of tropical tree species would not survive. Due to cyclic droughts which results in crop failure and death of livestock, the inh...

Provision of woodfuel is an important ecosystem service of dry forests and woodlands. However, charcoal production through selective logging of preferred hardwood species has the potential to alter the physiognomic composition of the residual or re-growth woodlands and may lead to their deterioration and degradation. This study, conducted through f...

Charcoal is among the most important domestic fuels in many countries of Sub-Saharan Africa (SSA). Its production has been conventionally considered as an agricultural off-season activity to supplement household income and cope with harvest failures. This study used primary data at the household level from an important charcoal supplying dryland re...

Woodfuel plays a critical role in energy provision in sub-Saharan Africa (SSA), and is predicted to remain dominant within the energy portfolio of the population in the coming decades. Although current inefficient technologies of production and consumption are associated with negative socio-economic and environmental outcomes, projected charcoal in...

Charcoal supplies over 30% of urban population and 7% of rural population with energy in Kenya. Most of the charcoal is produced in dry forests unsustainably leading to their continued degradation. This study was done in Kitui county of Kenya to evaluate the effect selective logging for charcoal production on tree species composition by comparing i...

Biofuels have gained significant importance in the past decade as the world struggles to addresses the problem of the ever increasing fossil fuels prices and global warming. As the world energy demand continues to grow in line with economic development and population growth, the increase in the price of fossil fuels will put more pressure on the ne...
