Measurement of the likely magnitude of the economic impact of climate change on African agriculture has been a challenge. Using data from a survey of more than 9,000 farmers across 11 African countries, a cross-sectional approach estimates how farm net revenues are affected by climate change compared with current mean temperature. Revenues fall with warming for dryland crops (temperature elasticity of -1.9) and livestock (-5.4), whereas revenues rise for irrigated crops (elasticity of 0.5), which are located in relatively cool parts of Africa and are buffered by irrigation from the effects of warming. At first, warming has little net aggregate effect as the gains for irrigated crops offset the losses for dryland crops and livestock. Warming, however, will likely reduce dryland farm income immediately. The final effects will also depend on changes in precipitation, because revenues from all farm types increase with precipitation. Because irrigated farms are less sensitive to climate, where water is available, irrigation is a practical adaptation to climate change in Africa.

Globalisation has heralded burgeoning ship movements and maritime operations in ports alongside increased international concerns regarding potential environmental impacts. In particular, smaller ports require accessible tools to manage them. A framework to facilitate environmental management applies business process principles to identify relevant inputs, processes and outputs. A case study of Falmouth Harbour Commissioners compares functional units and flows that define input-output processes for anchoring and bunkering operations. Strategic-level processes affect present and future operations while tactical service processes guarantee service level and quality through their integrity. Operational processes occur at the output level. An accessible generic framework supports planning of more sustainable maritime operations, facilitates mitigation of potential risks and encourages authorities to engage with sustainability agendas and manage development proposals proactively. Ongoing interlocution with business strategists will refocus port managers on educational and commercial missions and increase stakeholder engagement. Simplification and optimisation phases of business process re-engineering remain untapped by business strategists.

Abstract. An empirical investigation is undertaken into the impact of the Structural Adjustment Programme (SAP) on forest and biodiversity loss in Ghana between the period 1965-1995. In the first part of the analysis, a four-equation recursive model, consisting of forest loss, cocoa land, maize land and timber production equations, is employed to examine the impact of the SAP on forest loss. The first equation is a function of the last three, and the last three are functions of mainly prices. Piecewise linear and switching regression approaches are used to distinguish between the influence of the post from the pre-adjustment impacts. These results together with a specie-forest area relationship are used to investigate the impact of the SAP on biodiversity loss. The overall results indicate that cocoa land expansion and timber production, but not maize land expansion, are the significant causes of forest loss in Ghana. However, the impact on forest loss in the postadjustment period was reduced. The rate of biodiversity loss also reduced in the post-adjustment period. Changes in relative output and input prices due to the SAP may have played a significant role in the reduced impact of agricultural and timber related deforestation and biodiversity loss in the post-adjustment period.
