Native prairie is recognized in Alberta for its significant ecological, cultural and economic value. Much of the remaining prairie in Alberta is under public ownership and is managed for multiple uses and values. This paper illustrates how public land managers and industry cooperate to minimize disturbance to this valuable resource. The emphasis at the planning stage is proper inventory and identification of sensitive landscape, plant and animal features on proposed alignments, followed by appropriate realignment or mitigative action. At the pre-construction phase, environmental training of staff has raised awareness about the value of the prairie resource. During construction, the implementation of traffic control plans, shut down criteria and innovative soil handling techniques have reduced the overall impact of activities. Use of special equipment, erosion control techniques and revegetation strategies during reclamation can enhance the recovery of prairie disturbances. Proper monitoring is an important component of successful reclamation, and can lead to modifications of methods and equipment that give better future protection to this valuable landscape.

Current Trends

The main concern of this paper is with the limitations of techniques already commonly applied, and in the more promising points of application for new technology in navigation, surveillance and traffic control. In seeking the latter, some of the current trends in other fields, particularly aircraft design, are taken into account. Considerable emphasis is placed on the efficient use of land at airports, in view of the strength of feelings aroused in ‘the community’ by the questions of apportionment and exploitation of land resources.

Chili plants are one of the horticultural commodities that have economic value and are widely planted in Sungai Geringging Village, Kampar Kiri District, Kampar Regency. The main obstacle in achieving the quantity and quality of chili production is the attack of pests and diseases. This service aims to provide knowledge to chili farmers in Sungai Geringging Village about the types of pest and disease that attack chilies, symptoms of attack, and methods of control. The extension methods are lectures, questions and answers, discussions, demonstrations and practices with regard to chili plants. Extension is in the form of indoor presentation using LCD and in-focus tools by demonstrating the types of pest and disease that attack chilies and their attack symptoms, discussion and question and answer about pests and diseases of chili plants and their control techniques. Service programs in the form of counseling and demonstrations have been very well responded by chili farmers, counseling and demonstrations with material on how to introduce and control chili pests have never been received, plus in the cultivation of chili plants the obstacles that are often faced by farmers are problems with pests and diseases therefore participating farmers pay closer attention.

Mode Of Transport

The necessity to transport goods has always been a crucial component of everysociety. It is difficult to imagine a modern country without an advanced transport network andtechnology, which is why the latest computer systems have been developed over the past decades tomeet the needs of carriers. The study of this logistics segment shows that the complexity of thetechnological process of international intermodal transportation causes a range of problems to allparties involved in transportation. An advanced transport network provides a large number ofpossible options for the transportation of goods or commodities. That is why the computerization ofthe planning process is the next step in the evolution of transport logistics. This article describes theusage of software based on genetic algorithms to settle and improve the use of commercialIncoterms 2020. Taking into account all the limitations of existing software, it is proposed to use aheuristic approach to find the optimum transportation option and automate the planning process.Ukraine has always assigned a priority role to the railway mode of transport. This is why therailway industry has always been an integral part of the multimodal transportation process.Analysis of imports and exports shows stable growth over the past ten year period. Additionally,Ukraine enjoys a very advantageous geographical location, in that four important transportcorridors cross the territory of our country. Studies indicate that innovations in this area willpositively contribute to the credibility of Ukrainian carriers. Further, the article describes thetypical problems that arise during the usage of the basic Incoterms terms of delivery, including thecomplexity of customs procedures and clearance of goods, as well as unforeseen monetary costsarising from the difference in the laws of the countries participating in the transportation process.The author proposes the automation of the transportation planning process as a key to solving thesedisadvantages. The proposed innovation does not require significant investment and can createpositive economic value by substantially reducing the cost of transportation.

Excessive use of potable water in irrigation can be reduced considerably through treated wastewater reuse specially when fresh water resources in Qatar are scarce and the water supply depends on the limited groundwater and costly desalinated water. In view of the use of treated effluent in irrigation, the infiltration of brackish groundwater into the sewerage system should be eliminated and stringent standards to control leakages should be laid for new construction. The wastewater treatment methods and the effluent quality in general meet the criteria and standards governing the use of effluent in irrigation of landscape and agriculture. The reuse plan controls pollution by eliminating discharge of the wastewater to the gulf and contributes to the aesthetic and economic value of the area. The development of green areas along the roadside reservations and sidewalks through effluent reuse has been successful.The cultivation of fodder crops and development of forestry through effluent irrigation in agricultural farms far from the centre of population seems feasible and safe. However it is necessary to consider and evaluate the social and religious factors at the planning stage of the reuse schemes. With adequate planning,surviellance programme,health education,training of workers and awareness amongst the population, effluent reuse can be practised with minimum health risk and confidence can be established in the users.

Abstract The Florida Nurserymen and Growers Association (FNGA) and the Florida Exotic Pest Plant Council (FLEPPC) recently asked nurserymen to stop production of 45 potentially invasive plant species that are relatively insignificant in the ornamental horticulture market. Controversies surround 14 additional species designated as invasive by the FLEPPC, but which are highly ornamental, widely used in landscaping, or have high economic value according to the FNGA. A mail survey of Florida ornamental nursery growers identified sales volume and value for each of these species. Economic output and employment impacts were calculated to determine the effect phasing-out these species may have on Florida's nursery industry. Total statewide sales of the 14 species were estimated at $45 million in 2001, with $34 million in-state and $11 million out-of-state. These sales translate into combined economic output impacts of $59 million and employment impacts of 800 jobs for Florida's economy, accounting for about 3% of total statewide output and employment impacts created by the ornamental nursery industry. These estimated impacts should not be interpreted as the expected industry loss from a phase-out of these species. If a species is not available for purchase, consumers will probably substitute alternative species, reducing the effect of any phase-out.
