| Summary/Abstract |
This paper examines how a boom in industrial cassava served as a ‘gateway’ to intensify capitalist relations in Cambodia's north eastern borderland. Situated on Cambodia's border with Vietnam, Mondulkiri province has experienced a rapid increase in cassava production and trade since 2006, with transformative consequences for the region's forests and farmers. Using field data from 2012 to 2014, we explore how the boom ignited and intensified over time, through a conjuncture of conditions. Alongside strong market demand for cassava, these included resource abundance (soil fertility, timber, land, labour), connectivity to markets and cross border networks, and facilitative governance conditions. Over time, the boom strengthened capitalist relations, particularly through farmer debt and the revalorisation and accumulation of land. However, unlike booms of tree crops elsewhere, we argue that it is the very impermanence of cassava that is formative here, because the crop's short-term nature and low overheads facilitate practices like land laundering and land mortgaging. Like the ‘gateway drugs’ that were believed to place users on a path to addiction and risk, this paper shows that gateway crops such as cassava may similarly place farmers on a trajectory of more intense competition and reduced choice in their engagements with capitalist modes of production.

| Summary/Abstract |
Increasing energy use and the need to mitigate climate change make production of liquid biofuels a high priority. Farmers respond worldwide to this increasing demand by converting forests and grassland into biofuel crops, but whether biofuels offer carbon savings depends on the carbon emissions that occur when land use is changed to biofuel crops. This paper reports the results of a study on cassava-based bioethanol production undertaken in the Sikasso region in Southern Mali. The paper outlines the estimated impacts on above-ground carbon stocks when land use is changed to increase cassava production. The results show that expansion of cassava production for bioethanol will most likely lead to the conversion of fallow areas to cassava. A land use change from fallow to cassava creates a reduction in the above-ground carbon stocks in the order of 4-13 Mg C ha-1, depending on (a) the age of the fallow, (b) the allometric equation used and (c) whether all trees are removed or the larger, useful trees are preserved. This 'carbon debt' associated with the above-ground biomass loss would take 8-25 years to repay if fossil fuels are replaced with cassava-based bioethanol.

| Summary/Abstract |
Despite being a major petroleum producing and exporting country, Nigeria has for a long time imported refined petroleum products for domestic consumption. The country has recently made an entrance into the bio-energy sector by seeding the market with imported ethanol until enough capability exists for the domestic production of ethanol. The Nigerian Biofuel Policy was released in 2007 calling for the domestic production of bio-ethanol to meet the national demand of 5.14 billion litres/year. Some investors have responded by investing over $3.86 billion for the construction of 19 ethanol bio-refineries, 10,000 units of mini-refineries and feedstock plantations for the production of over 2.66 billion litres of fuel grade ethanol per annum. Also, another 14 new projects are in the offing. Of the 20 pioneer projects, 4 are at the conception phase, 8 are in the planning phase, and 7 are under construction with only 1 operational. The potential benefits of the emerging bio-ethanol projects include investment in the economy, employment, energy security and boost rural infrastructure, while the major challenge is land take (859,561 ha). This is the first time an attempt is been made to document the emerging bio-ethanol projects in Nigeria.
