Long-term annual burning of grassland increases CO2 emissions from soils
Grasslands have potential to mitigate against climate change because of their large capacity to store soil organic
carbon (SOC). However, the long-term impact of grassland management such as burning, which is still common
in ...
Seed Info No. 49
Seed Info aims to stimulate information exchange and regular communication among seed staff in the Central and West Asia and North Africa (CWANA) region and beyond. Its purpose is to help strengthen national seed programs ...
Congruence of appropriation and provision in collective water provision in Central Namibia
Achieving cooperation in natural resource management is always
a challenge when incentives exist for an individual to maximise her short term
benefits at the cost of a group. We study a public good social dilemma in ...
Evidence that dicot-infecting mastreviruses arep articularly prone to inter-species recombination and have likely been circulating in Australia for longer than in Africa and the Middle East
Viruses of the genus Mastrevirus (family Geminiviridae) are transmitted by leafhoppers and infect either mono- or dicotyledonous plants. Here we have determined the full length sequences of 49 dicot-infecting mastrevirus ...
Cactusnet: Promoting the social and ecological benefits of cactus production: Cactus Pear in South Africa: History, challenges and potential
Given the fear of potential invasions by cacti, there is resistance among government officials and farmers to promote the use of spineless Cactus Pear varieties in South Africa. This presents a missed opportunity to utilize ...
Gender, Rights, and the Politics of Productivity: The Case of the Flag Boshielo Irrigation Scheme, South Africa
Can South Africa's world renowned constitutional socio-economic rights
to access to sufficient water and food be realized by technology-driven
capital-intensive economic growth, especially agricultural growth, or
are there ...
Influence of putative forest refugia and biogeographic barriers on the level and distribution of genetic variation in an African savannah tree, Khaya senegalensis (Desr.) A. Juss
Phylogeographic studies of tropical and subtropical
tree species provide an ideal method to study the role of forest
refugia in the structuring of genetic diversity in contemporary
populations. To date, most studies have ...
Joint venture Schemes in Limpopo Province and their outcomes on smallholder farmers livelihoods
Joint Venture schemes based on the floppy irrigation technology are being promoted in the post-
Apartheid South Africa's Limpopo Province. Access to land and water resources in South Africa are
largely viewed as a mechanism ...
Spatial Variation in Tree Density and Estimated Aboveground Carbon Stocks in Southern Africa
Variability in woody plant species, vegetation assemblages and anthropogenic activities derails the efforts to have common approaches for estimating biomass and carbon stocks in Africa. In order to suggest management ...
Potential of grassland rehabilitation through high density-short duration grazing to sequester atmospheric carbon
According to the World Resources Institute (2000), a relative increase of carbon (C) stocks in world soils by 0.4% per year would be
sufficient to compensate all anthropogenic greenhouse gas emissions. Several land management ...
