Обозначена важнейшая роль защитных лесных насаждений в вопросе защиты сельскохозяйственных земель от негативных процессов ветровой и водной эрозии, роста оврагов и значительного промерзания. Рассмотрены существующие конструкции лесных полос, являющихся частью защитных лесных насаждений. Отмечено неудовлетворительное состояние большинства существующих защитных лесополос, вследствие чего необходим ремонт либо реконструкция данных насаждений. Показана перспективность применения крупномерного посадочного материала, пересаживаемого с комом почвы, при выполнении работ по защитному лесоразведению. Представлена разработанная конструкция выкопочной машины. Орудие агрегатируется с трактором и применяется для работы в лесных питомниках, где наблюдается рядное размещение выкапываемых растений. Для повышения эффективности процесса заготовки посадочного материала с возможностью работы под пологом леса разработано технологическое оборудование для выкопки и пересадки крупномерных саженцев, размещаемое на базе гидроманипуляторных установок. Представленные машины могут также применяться для подготовки посадочных мест под посадку ими же выкопанных саженцев. При этом образованное посадочное место будет полностью повторять контуры кома почвы высаживаемого растения. Рассмотрены положения Стратегии развития защитного лесоразведения в Российской Федерации до 2020 года. Выявлена необходимость создания 4 млн га защитных лесных насаждений для устранения негативных процессов эрозии и опустынивания сельскохозяйственных земель и предотвращения дальнейшей деградации агротерриторий. Предложенная технология использования крупномерного посадочного материала в защитном лесоразведении и средства механизации процесса выкопки и пересадки саженцев с комом почвы позволяют повысить эффективность и качество создания, ремонта или реконструкции защитных лесных полос. The most important role of protective forest plantations in the issue of protecting agricultural lands from negative processes of wind and water erosion, ravine growth and frost penetration is indicated. Considered are the existing structures of forest strips that are part of protective forest plantations. The dissatisfactory condition of the many of the existing protective forest strips is noted, as a result of which it is necessary to repair or reconstruct these plantations. The prospects of using large planting material, transplanted with a soil clod, are shown when performing protective afforestation work. The developed plant lifter design is presented. The tool is aggregated with a tractor and is used for work in forest nurseries, where in-line escapement of lifting plants is observed. To improve the efficiency of the planting material harvesting process with the ability to work under the forest canopy, technological equipment has been developed for lifting and transplanting large plantlets, located on the basis of grapple plants. Presented machines can also be used to prepare planting places for planting them with excavated plantlets. In this case, the formed planting place will completely repeat the contours of the plant being planted soil clod. The provisions of the Strategy for the development of protective afforestation in the Russian Federation until 2020 are considered. The need to create 4 million hectares of protective forest plantations for eliminating the negative processes of erosion and desertification of agricultural lands and preventing further degradation of agroterritories was identified. The proposed technology for the use of large planting material in protective afforestation and the means for mechanization of the process of lifting and transplanting plantlets with a soil clod make it possible to improve the efficiency and quality of the creation, repair or reconstruction of protective forest strips.

In the modern conditions of society development the role of protective plantings is great importance. In particular, types of such plantations in the study are protective strips along the roads. At first glance, it is difficult to trace the processes that take place in these lanes. However, by selecting the appropriate adapted research methodology, it is possible to trace these seemingly hidden functions. The significance and relevance the use of roadside forest strips in the context of their noise-absorbing functions are presented. Attention is paid to the analysis of noise load for the operation of large vehicles on highways of international and national importance in the conditions of Western Polissya. An analysis of recent scientific publications with an emphasis on protective plantings as an effective means of preventing negative acoustic loads. The main purpose of the research was to determine the noise-absorbing properties of roadside forest belts depending on their design features and species composition. It is noted that the solution of program tasks of work is carried out with the use of special techniques of researches of noise-absorbing effect by protective forest plantations on transport ways. The comparative characteristic of noise-absorbing effect roadside forest strips and noise-protective screens are executed. On the basis of the conducted researches the mathematical models describing a decrease in noise level depending on a design of roadside forest strips are developed. The generalization of the experimental results showed that the roadside strips of dense and openwork structures are marked by the highest quality noise-absorbing effect. Noise protection screens in the study area help to reduce the noise level to 60 dB and less, it than ensure compliance with the necessary sanitary standards for settlements.

This chapter discusses national literary histories in Australia, Canada, New Zealand, and the South Pacific and summarises the book's main findings regarding the construction and revision of narratives of national identity since 1950. In colonial and postcolonial cultures, literary history is often based on a paradox that says much about their evolving sense of collective identity, but perhaps even more about the strains within it. The chapter considers the complications typical of postcolonial literary history by focusing on the conflict between collective celebration and its refutation. It examines three issues relating to the histories of English-language fiction in Australia, Canada, New Zealand, and the South Pacific: problems of chronology and beginnings, with a special emphasis on Indigenous peoples; the role of the cultural elite and the history wars in the Australian context; and the influence of postcolonial networks on historical methodology.

Inspired by recent epistemological and ontological debates aimed at unsettling and reshaping conceptions of language, this essay discusses how mainstream sociolinguistics offers notions meaningful for studying contexts of the South. Based on empirical studies of youth in two African cities, Yaoundé in Cameroon and Maputo in Mozambique, the essay engages with “fluid modernity” and “enregisterment” to unravel the role that fluid multilingual practices play in the social lives of urban youth. The empirically grounded theoretical discussion shows how recent epistemologies and ontologies offer inroads to more pluriversal knowledge production. The essay foregrounds: i) the role of language in the sociopolitical battles of control over resources, and ii) speakers’ reflexivity and metapragmatic awareness of register formations of fluid multilingual practices. Moreover, it shows how bundles of localized meanings construct belongings and counterhegemonic discourses, as well as demonstrating speakers’ differential valuations and perceptions of boundaries and transgressions across social space.
