Abstract. A risk reduction program was developed after debris-flow disaster analysis is conducted using mitigation structures, evacuation measures and community restrained expansion strategy. The risk assessment method delineates hazard zones and analyzes vulnerability and the resilient capacity of an affected area, allowing the prediction of losses of properties and lives, and the corresponding risk. It can also be used to evaluate performance of a risk reduction program. The proposed method was applied to the Songhe community as a case study to assess debris-flow risk and performance of reduction programs consisting of mitigation structures, evacuation measures and a restrained expansion strategy. Total annual risk decreased to $0.01 million from $0.72 million for the No. 1 Torrent and to $0.36 million from $1.22 million for the No. 2 Torrent after mitigation structures were installed, and evacuation measures were implemented based on restrained expansion. Although mitigation structures are costly, they can reduce the size of hazard zones. Delimitating the Designated Soil and Water Conservation Area restrains community expansion and decreases possible losses. Although evacuation measures cannot reduce the size of hazard zones, they effectively increase the resilient capacity of residents. The benefit-cost ratio for mitigation structures exceeds 1.0 for both torrents with an average of 3.87; the benefit-cost ratio for evacuation measures is markedly greater than 1.0. Combining mitigation structures and evacuation measures increases the total benefit with a benefit-cost ratio of 4.38. Analytical results showed that the risk reduction program is cost-effective.

Abstract Both artificial and living snowfences are used to protect roads from blowing and drifting snow. This article evaluates and compares the economic performance of three snowfence designs--the Wyoming and double-row slatted artificial snowfences and a three-row living snowfence. The economic analysis evaluates the snowfences by applying four economic performance indicators: total net benefits, present net value, benefit/cost ratio, and annual breakeven benefits. The study uses snow removal savings and accident reduction benefit information from a case study in the state of Wyoming. The case study results show all the designs are economically efficient when used for road protection. However, the living snowfence outperformed the other designs in three of the four economic performance indicator categories. The largest proportion of total costs of the Wyoming and living snowfence are establishment costs whereas the bulk of total cost of the double-row slatted snowfence is for maintenance. The economic performance of all the snowfences is most sensitive to changes in their useful or effective lives. The procedures and general conclusions of the study can be applied to similar cases elsewhere. West. J. Appl. For. 15(2):70-74.

The economic assessment of transportation projects is evolving from a reliance on user benefits (travel time, cost, or safety) to encompass a wider spectrum of potential benefits, fostered by advances in economics and recognition that different project modes deliver different portfolios of benefits. Sponsors develop projects to address specific problems in their communities. This progression in how investments are evaluated opens the door for projects whose outcomes span a variety of benefit categories rather than concentrating on traditional user benefits and permits an improved intermodal comparison of candidate investments. Transit and intercity rail projects are particular beneficiaries of the broader project assessment approach. This paper presents a case study of how a comprehensive approach to project assessment was applied to the Northern Lights Express project that would reintroduce passenger rail service between the cities of Minneapolis and Duluth, Minnesota, the state's largest economies. Owned and operated by BNSF Railway, Amtrak's service in the corridor ended in 1985. Six stations are planned: Target Field in Minneapolis; stations in Coon Rapids, Cambridge, and Hinckley, Minnesota; a station in Superior, Wisconsin; and Union Depot in Duluth. The goal for the analysis was threefold: ( a) to confirm that the investment would yield a positive return; ( b) to communicate with partners, stakeholders, and the public about the project's expected outcomes; and ( c) to contribute to the selection of an alternative. The benefit–cost ratio was estimated for eight alternatives that varied by physical alignment and service plan.

The present study for performance evaluation newly developed varieties of CIM –Kranti and other varieties of menthol mint cultivation has been carried out at farmers’ field of central Uttar Pradesh. Mints are commonly used as the source of fragrance, flavor and pharmaceuticals industry. During the study period 2017-18, 100 farmers cultivating CIM-Kranti and other varieties have been selected from the region of central Uttar Pradesh. The primary data were collected from the selected farmer’s field on profitability comparison between CIM-Kranti and other varieties under cultivation. The highest area and production has been observed during 2012 and 2013. Simple statistical tools and techniques have been used for data analysis of the cost of cultivation and profitability. It has been observed during the study that CIM-Kranti gives higher returns (.98491/- ha/year) over other varieties (.70977/-ha/year). However, the input cost of CIM-Kranti is higher than other varieties of the crop but the net return of CIM-Kranti was more profitable than other varieties. The benefit cost ratio has been observed 1.45 and 1.74 of other varieties and CIM-Kranti respectively. The new variety “CIM-Kranti” of menthol mint is cold and frost tolerant and has the potential to produce 10-15% more oil i.e. 145-160 kg/ha in summer season as compared to all other popular commercial cultivars of menthol mint.It is suggested from the study that maximum profit is generated through CIM-Kranti cultivation followed by other varieties crop.

Ghana has had a long-standing problem of illegal gold mining that has led to the destruction of the environment. The government of Ghana is taking steps to not only curb illegal mining but also to restore destroyed lands that resulted from illegal mining. The government intends to spend financially in the area of ecological restoration to returned disturbed lands to their natural states possible, but the question remains whether restoring those disturbed lands will be beneficial to the country. The study was undertaken in Bekwai Municipal Area in the Ashanti region of Ghana where most locals are farmers. The research studies whether the benefits of ecological restoration outweigh the cost of ecological restoration? The research deployed a quantitative data collection. The data collected was analyzed using benefit-Cost ratio. The result shows that the benefit of ecological restoration outweighs the cost incurred as dependent on the land use as a carbon sequestration project. In conclusion, investment in ecological restoration is a step in the right direction for a country endowed with gold resources. This will spur growth and at the same time improve and protect the country’s natural resources and environment.

Transportation research projects are a vital element for transportation agencies to accumulate new technology and knowledge to improve the efficiency and safety of transportation infrastructure. The purpose of this paper is to develop benefit cost analysis (BCA) tools to assist transportation agencies in evaluating transportation research projects. The BCA tools provide analysis methods for estimating the benefits for changes in the level of service (LOS) of a roadway, reductions in the vehicle travel time, changes in vehicle operating costs and reductions in the number of crashes. Three case studies were investigated to illustrate the usage of the BCA tools. The first case study evaluated the effectiveness of variable speed limit systems implemented along I-80 in southern Wyoming. The BCA tools estimated a benefit cost ratio of 6.64 indicating that the implementation of the project was economically justifiable. The second case study was a recent study investigating and developing mitigation strategies for the effects of truck traffic along the I-80 in southern Wyoming resulting in a benefit cost ratio of a 9.23 indicating that the project had the potential to be economically viable upon implementation. The final case study evaluated the effect of wildlife overpass and underpass crossings on the migrations of pronghorn and mule deer. The benefit cost ratio for the research project was 0.42 indicating that the project was not economically beneficial after the first year of implementation. The case studies indicated that the BCA tools are a beneficial tool for quantifying the economic benefits of a transportation research project.

A survey study was conducted to study the benefit-cost analysis of apiculture enterprise in Jutpani VDC, Chitwan district. Data were collected by interviewing randomly selected 18 beekeepers for sample survey. Benefit : Cost (BC) ratio of apiculture was computed by including and excluding the revenue obtained from colony selling. Only 61.11% of beekeepers sold bee colonies for earning income. The study revealed that BC ratios of apiculture were 2.41 and 1.58 in the case of inclusion and exclusion of the income received from the colony selling, respectively. It showed that apiculture industry was running in profit in both cases. In the former case, the BC ratio ranged from 0.97 to 6.22 and about 88.88% beekeepers were in profit. The BC ratio in the later case ranged from 0.43 to 3.41 and about 77.77% beekeepers were in profit. The number of colonies ranged from 2 to 54 with an average of 21.33 colonies per bee farm. In the former case, average annual income was Rs. 70758.33 (US$ 969.29 approximately) per farm and Rs. 49588.31 (US$ 679.29 approximately) in the later case. Likewise, the average income per colony per annum was Rs. 3317.31 (US$ 45.44) and Rs. 1777.65 (US$ 24.35 approximately) in the former and later case, respectively.
