<p>Prolonged drought and floods as a result of climate change are a serious problem for households at Mpolonjeni ADP because their livelihood is mainly rainfedfarming. This is evident as there is high level of food insecurity, crop failure, poverty and hunger, which has forced many households to abandon farming and survive by food aid. The study was a descriptive survey aimed to identify private adaptation strategies to climate change and conduct a cost benefit analysis for the identified adaptation strategies. A stratified random samplingtechnique was used to select 350 households. Personal interviews were conducted using structured questionnaires. Data were analysed using descriptive statistics and cost benefit analysis where net present value (NPV) and internal rate of return (IRR) were used as decision rules. Adaptation strategies used were; drought resistant varieties, switching crops, irrigation, crop rotation, mulching, minimum tillage, early planting, late planting and intercropping. Switching crops had the highest NPV, where maize (E14.40) should be substituted with drought tolerant crops such as cotton (E1864.40), sorghum (E283.30) and dry beans (E292.20). The study recommends that households should grow drought tolerant crops such as cotton, sorghum and dry beans instead of maize. The government should provide irrigation infrastructure, such as dams, strengthen extension services and subsidise farm inputs in order to improve crop production.</p>

Climate change continues to hamper crop-based systems across sub-Sahara Africa. Adaptation strategies prove to be effective at improving production and enhancing livelihoods of farm households. This study employs Cost-Benefit Analysis (CBA) to assess the perceived economic profitability of adopting various on-farm climate change adaptation strategies among farmers in Zabzugu and South Tongu districts in the north and south of Ghana. A simple random sampling approach was used to select 300 farmers who had previously benefited from climate change projects. Major strategies adopted in both districts were: changing of planting dates, planting early maturing varieties, row planting, seed refilling and planting drought tolerant varieties. Adoption intensity was high in Zabzugu district compared to the South Tongu District. Generally, the adoption of each strategy was perceived to be profitable since the estimated average benefits outweighed the average costs. However, the most profitable strategies were strip cropping, repeated sowing, refilling, zero tillage and row planting. Less profitable strategies included land rotation, mixed farming, early planting, tractor ploughing and “A-frame” contour farming. Among others, drought tolerant varieties of rice, maize and soybeans, as well as zero tillage, repeated sowing and strip cropping, should be promoted and farmers encouraged to adopt these practices for enhanced benefits.

The paper analyzes shortcomings of economic impact studies based mainly on input- output models that are often employed in Russia as well as abroad. Using studies about sport events in the USA and Olympic Games that took place during the last 30 years we reveal advantages of the cost-benefit analysis approach in obtaining unbiased assessments of public investments efficiency; the step-by-step method of cost-benefit analysis is presented in the paper as well. We employ the project of Sochi-2014 Winter Olympic and Paralympic Games in Russia to evaluate its efficiency using cost-benefit analysis for five accounts (areas of impact), namely government, households, environment, economic development, and social development, and calculate the net present value of the project taking into account its possible alternatives. In conclusion we suggest several policy directions that would enhance public investment efficiency within the Sochi-2014 Olympics.

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

This paper offers a general guide on how to conduct a proper economic analysis for community-based intervention projects. Identification and quantification of costs and benefits are the focus of the cost benefit analysis. We categorize costs and benefits from human and physical perspectives and pay special attention to the measures of saving human lives accompanied by the proposed calculation methods. We recommend net present value and benefit-cost ratio as the criteria to assess projects and highlight some challenges remaining in the analysis.

This paper explores the lessons learnt from the Optimising Adaptation Investment projects for the Department of Climate Change and Energy Efficiency–it includes coastal settlements, water supply and rail infrastructure case studies. These projects are the first of their kind in Australia and are considered internationally as a leading example of economic cost benefit analysis. They have been used effectively to inform decision making on specific adaptation responses to climate change risks to existing and new infrastructure. The lessons learnt will be explored for offshore platforms, ports, rail, road, drainage, tailings dams, mine facilities, water, and power supply, which includes the following elements: What decision makers require to make informed decisions under the uncertainty of climate change impacts. Reducing the uncertainty through economic modelling and cost benefit analysis. Optimising the right timing and scale of various adaptation options. Benefiting from oil and gas infrastructure adaptation opportunities. To further support the elements above, the applied process for integrating climate adaptation into infrastructure planning, design and operation will be illustrated by AECOM project experiences. AECOM has completed more than 60 significant climate change risk and adaptation projects for mines, ports, water supply and treatment, energy generation, transmission and distribution, rail, road, and coastal settlements in Australia, including the report: Climate Change Impacts to Infrastructure in Australia for the Garnaut Climate Change Review.

This paper presents the operational procedures involved in incorporating the environmental costs in the cost–benefit analysis of a hydro-electric project. The proposed project, if implemented, would result in the loss of 2,800 hectares of tropical forests and dislocation of two settlements of about 200 families who are currently dependent on the forests for their livelihood. The forests are mainly used for extracting reed – a material used both by traditional artisans and the paper-pulp industry. The potential environmental costs and benefits of the project are identified and approximate estimates of some of these costs are made for items such as carbon sequestration, bio-diversity, and so on, based on similar estimates made elsewhere. These estimated environmental costs are incorporated into the analysis, and the hypothetical estimate of the non-use value, which would make the project's net benefit zero, is estimated under different discount rates. The analysis brings into sharp focus some crucial factors that have a direct bearing on the social trade-off involved in the project choice.
