Arthropod Pest Management in Strawberry

Simple SummaryStrawberry is a commercially important crop which is produced and consumed globally. As there is an increase in economic significance of strawberry production, growers across the globe face challenges in protecting the crop against insect and mite pests. The damage from insect pests results in significant yield loss which adversely affects the strawberry industry. To overcome this situation, management of pests is warranted with reduced impact on the environment and beneficial organisms. Even though insecticide-driven management practices predominate in the strawberry production system, the use of non-chemical alternatives is also gaining importance. The current review is aimed at discussing the important pests of strawberry and various integrated pest management practices adopted worldwide to reduce the damage impact and improve production.The strawberry crop endures economic losses due to feeding injury from a number of phytophagous arthropod pests. A number of invasive pests have posed challenges to crop protection techniques in the strawberry cropping system recently. It is increasingly evident that sole reliance on chemical control options is not sustainable. In this review, current challenges and advances in integrated pest management of various strawberry pests are presented. Key pests discussed include thrips, mites, lygus bug, spotted wing drosophila, seed bug, weevils, aphids, whiteflies, and armyworms. Several integrated pest management techniques that include use of intercropping, resistant cultivars, irradiation with gamma rays, use of spectral sensitivity of pests, biological control agents and natural enemies, and biorational pesticides have recently been reported to be useful in managing the various strawberry pests. With the increase in world production of strawberry, several techniques will be necessary to manage the pest complex of strawberry.

The Green Paradox, A Hotelling Cul de Sac

The green paradox is an effect by which an increasing tax per unit on oil production, aimed at tracking damages from CO2 emissions, induces an increase in world production and a decrease in price in the near term. The increase is a rational response in a Hotelling exhaustible-resource model. We simulate the decisions of a price-taking producer in response to a tax of various shapes. In contrast to a Hotelling model, our extraction technology involves irreversible, lumpy investments in exploration and development. In addition, we assume output from a developed reserve is subject to natural decline at a rate that is determined by the sunk development investment and the geology of the reserve. Decisions are far more complicated, and results far subtler, than in the Hotelling framework. Given a price path, we show that almost any form of tax causes a reduction in the level of development and initial production, thereby contradicting the hypothesis of the green paradox.

Approaches to estimation of energy potential of renewable energy sources in the territory of Russia

The article is devoted to the definition of peculiarities and evaluation of the energy potential of renewable energy sources (RES) in the territory of Russia, as well as the application of this information as additional initial data in the territorial planning. This formulation of the research allows us to achieve the gradual introduction in the design practice of the use of RES for the development of settlements and industrial facilities. The article considers existing power plants of renewable energy sources, of which small hydroelectric power plants are both the first and at the same time promising in hydropower engineering. In addition, the publication presents a variety of experience in the use of equipment for generating energy based on renewable sources, as well as provides analytical data on the prospects for growth in world energy production. It should be noted that the greatest increase in world production is expected from technologies that receive energy based on the action of the sun. Among RES, wind power is on the second place, which was reflected in the further analysis, consideration of the issues of integration of renewable energy technologies in town-planning practice and the results of the research.Subject matter: the subject of the study is the possibility of applying renewable energy technologies in modern urban development.Objectives: the purpose of the study is to identify the most sources of renewable energy whose application is most rational in the development of settlements.Materials and methods: in the course of the work, the main advantages and disadvantages, as well as prospects for the development of various types of renewable energy sources, including small ones, were considered.Results: as a result of the work, conclusions were drawn about the possibility of implementing RES technologies in the environment of settlements with territorial planning and the need for their integrated application.Conclusions: application of renewable energy technologies is possible in modern urban planning.

LITHIUM: RESOURCES, PRODUCTION AND PROSPECTS OF WORLD MARKET DEVELOPMENT

The paper deals with lithium which is currently characterized by one of the fastest growth rates in terms of price, consumption and production volumes. We have estimated the rates of consumption, the growth in production volumes and the growth of the explored volumes of lithium mineral resources and have given forecast of development of the world lithium market, growth of lithium production and price dynamics. Thus, the increase in world production of lithium by 2020 should exceed 12,000 tons per year. The increase in the consumption of lithium is shown to stimulate the growth of geological exploration of its mineral resources and to lead to a sharp increase in the explored lithium reserves. Moreover, we have attempted to evaluate other lithium mineral resources including those with a low content of lithium. The analysis demonstrate that, in accordance with existing technologies and speed of the lithium production growth, lithium ore will run out in about 25 years, and lithium reserves of proven resources associated with salt lakes will be depleted in about 50 years. The paper suggests several ways of solving this problem. The first one is an increase in the extraction of lithium from existing sources of raw materials, that is, the use of more effective methods. The second one is the use of lean lithium resources, such as underground brines and associated oil waters which can become the most promising source of lithium (the possible directions and prospects of extraction have been shown). The third way is the use of secondary lithium resources and the processing of spent lithium batteries. Keywords: lithium; lithium market; world reserves of lithium; lithium mining; underground brines; associated oil waters.

Divisão Norte-Sul e o Desenvolvimento Sustentável: A Universalidade com Diferenciação Internacional das Responsabilidades Ambientais

O presente artigo objetiva analisar as implicações que a divisão Norte-Sul global enseja no debate do desenvolvimento sustentável. A raiz dessa divisão se reflete na própria criação, natureza e orientação do Direito Internacional do Meio Ambiente. O desenvolvimento sustentável convive com o questionamento se desenvolvimento e ambientalismo poderiam coexistir em virtude do progressivo aumento da produção e consumo mundiais. Nesse sentido, apresenta-se uma reflexão sobre a agenda ecológica do Norte global à luz da necessidade de redução da pobreza por meio do desenvolvimento para a proteção do meio ambiente no Sul global.

The kiwifruit in Chile and in the world

The kiwi is a fruit that, has only been in Europe for about 60 years, which signifies a great potential for the development of its consumption and great difficulty in the educational process of the product. Currently there is a growing increase in world production, which to date is above the growth in demand. This means that the kiwi categories are not growing significantly and, on the contrary, the kiwi is at a crossroad that will be resolved in the coming years. The changing global economic scenario affects high-value products such as kiwis, making it hard to predict their commercial results. The worldwide market has clearly indicated through the demand and the prices that it is interested in the sweeter yellow varieties. Asian markets have been and are expected to continue to grow. The increase in world production has also generated overlap in stocks between the hemispheres, which makes it necessary to closely monitor commercial strategies regarding the start and end of the season. In this way, the market entry of the southern hemisphere kiwifruit is conditioned according to the presence of fruit from the Northern Hemisphere. The unique features and uses of the kiwi make it one of the most interesting fruits present in the world. For this reason it is also a fruit with high purchase value. In spite of the described variables and market trends, there is a growing demand for consuming better quality kiwis and willingness to pay a higher price.

Use of glycerine in poultry diets

Continuous advances in the poultry industry have stimulated the use of alternative feeds in poultry diets, and in particular glycerine, given its availability via the increase in world production of biodiesel. Glycerol is the principal component of glycerine, and can be used as an energy source to replace e.g. corn. However, other residual compounds, such as methanol and high levels of sodium, limit its use in animal feeds in large quantities. Several studies have found that the nitrogen-corrected apparent metabolisable energy of glycerine (AMEn) varies significantly between broilers, laying hens and quail, due to different processing/extraction methods (via biodiesel production). However, an energetic availability of at least 85% has been verified. Knowledge of the main metabolic pathways of glycerol and other components of glycerine is important for future studies on this feed material and to determine its main limitations. Understanding the relationship between the quality of the glycerine and its role as a source of dietary energy will allow more precise inclusion of glycerine in the formulation of balanced diets, without negatively affecting the performance of poultry.

World supply and demand situation for oilseeds, oils, and meals

AbstractIn recent years, the demand for meal has been relatively stronger than for vegetable oils. Thus, we have to get the meal demand if we want to determine the extent of oil production and the requirements of oilseeds. This is true although the average annual increase in world meal consumption has declined from 5.5% during the five seasons ended 1970–71 to probably 3.8% in the following five seasons. The share of soybean meal is predominating and ever increasing from 49% ten years ago to as much as 61% this season.In most seasons, including the current one, soybean oil output is determined by the more rapidly increasing meal demand. It is thus often in surplus supply, specifically at present. The marketing of soybean oil is becoming even more difficult as world supplies of low‐cost palm oil and lauric oils are increasing more and more sharply.World supplies of oilseeds are developing in cycles of ca. seven years—three years buildup stocks and four years liquidation. The present expansion period, which ends this season, has been more pronounced owing to last season's severe economic recession which also affected the consumption of meals and oils/fats.Present prospects for the next five seasons point to a slowing‐down of the increase in world production of soybeans, soybean oil, and meal owing to a continuing sharp expansion of supplies of palm oil and lauric oils. This assumes that the general economic activity will more or less stagnate or show only a small expansion during this period.
