“…Recently, it has been the implicit or explicit motivation for large-scale afforestation to sequester carbon to reduce greenhouse gases (e.g. [17,18]). Large discrepancies between potential and actual woody biomass are taken as indicators of preferred sites for 'reforestation' for carbon sequestration [19].…”

Africa has the most extensive C4 grassy biomes of any continent. They are highly flammable accounting for greater than 70% of the world's burnt area. Much of Africa's savannas and grasslands occur in climates warm enough and wet enough to support closed forests. The combination of open grassy systems and the frequent fires they support have long been interpreted as anthropogenic artefacts caused by humans igniting frequent fires. True grasslands, it was believed, would be restricted to climates too dry or too cold to support closed woody vegetation. The idea that higher-rainfall savannas are anthropogenic and that fires are of human origin has led to initiatives to 'reforest' Africa's open grassy systems paid for by carbon credits under the assumption that the net effect of converting these system to forests would sequester carbon, reduce greenhouse gases and mitigate global warming. This paper reviews evidence for the antiquity of African grassy ecosystems and for the fires that they sustain. Africa's grassy biomes and the fires that maintain them are ancient and there is no support for the idea that humans caused large-scale deforestation. Indicators of old-growth grasslands are described. These can help distinguish secondary grasslands suitable for reforestation from ancient grasslands that should not be afforested.This article is part of the themed issue 'The interaction of fire and mankind'.

“…The grasslands have been extensively forested with pines and eucalyptus, justified from a conservation perspective by their supposed anthropogenic origins. Grasslands such as these have become prime targets for 'reforestation' motivated increasingly by carbon sequestration to reduce greenhouse gas emissions [18].…”

“…According to Canadell and Raupach (2008), terrestrial ecosystems remove nearly 3 billion tons of anthropogenic carbon every year, absorbing about 30% of all CO 2 emissions from fossil fuel burning and net deforestation. China has used 24 Mha of new forest plantations and natural forest regrowth to o¤set 21% of Chinese fossil fuel emissions in 2000.…”

Abstract:This paper shows that, if countries are farsighted when deciding whether to defect from a coalition, then the implementation of cleaner technologies may jeopardize the chances of reaching an international environmental agreement. The grand coalition may be destabilized by the implementation of cleaner technologies, ultimately resulting in higher global emissions and lower global welfare. We further show that the higher the stock of pollution at the instant when the cleaner technology is implemented, the more likely that the above mechanism unfolds. We examine a reduction in the emission per output ratio as well as measures that enhance the natural rate of decay of stock pollutants.JEL classi…cations: Q20, Q54, Q55, Q58, C73.

Mycorrhizal Interactions for Reforestation: Constraints to Dryland Agroforest in Brazil

Reforestation provides restoration of forest ecosystem services including improved soil fertility, which leads to increased productivity and/or sustainability of the system. Trees also increase the average carbon stocks providing wood supply for local communities; however, C sequestration strategies highlight tree plantations without considering their full environmental consequences, such as losses in stream flow. The productivity of a site is a consequence of their physical, chemical, and biological properties, resulting in natural fertile soils or adequate managed soils for improved quality. Thus, it is required to know the variations in the properties of land-use systems for adoptability of agroforestry innovations. The choice of agroforestry tree species (highly mycorrhizal dependent plants should be selected) would have great implications for the manipulation of arbuscular mycorrhizas's species. In dry forest, the inevitable consequence of cutting has been the loss of vegetation cover and insufficient scientific information on the capacity to optimize forest recuperation affects agroforestry adoption. To study the biological properties of soils is now of interest; therefore, this paper reviews the literature that has hitherto been published on mycorrhizal interactions for reforestation and points out the use of mycorrhizal technology as one of the alternatives to improve forest products and environmental quality.
