Abstract:
Mass production of insects is calling for environmentally optimised and economically efficient insect value chains. It is a complex task considering a great variety in insect species, production scales, feed formulations, etc. Taking a challenge of environmental impact clarification, a few studies highlight on life cycle assessment (LCA) of insect production. The current study is aimed to systemise 24 selected previous studies to establish a modular framework for the determination of contribution of sustainability assessment factors of insect production chains. Reviewing published studies according to the elements of LCA, the study identified a feasible approach for the modelling of insect production chains, which can be used for the facilitation of comparability of further LCA studies. The approach is based on a modular analysis of insect production through a graphical mapping of value chains (allowed identification of precise system boundaries) supplemented with table analysis considering scale of production, reference (functional) unit, impact assessment methodology and type of LCA. Such an approach allows for consistency in LCA setting and further comparability of results.

Abstract:
The socio-economic development of Ukraine requires increasing the level of food security of the state, providing the population with high-quality and ecologically safe food products in order to preserve their health and improve the welfare of society. The safety of food for the health of the population can be guaranteed only under the condition of organizing strict quality control of food products entering the domestic market, as well as through the implementation of a stimulating policy for the production of ecological products. In this connection, there is an objective need to develop and introduce a set of coordinated organizational and economic measures, which should be based on stricter public, state and self-government control over compliance with established norms and standards regarding production technologies and be implemented at all stages of the product life cycle. An important role in this context will be played by increasing the social responsibility of business, popularization of environmentally safe and energy-saving technologies, greening of all production and consumption processes, which requires coordinated cooperation of managers, managers and employees of agricultural, agro-industrial and processing enterprises, scientists, educators and the public. The legal regulation of the agro-industrial complex of Ukraine has the greatest influence on the regulation of ecologically safe production of agricultural products. Ecological safety of agricultural products is the state of agricultural products, in which the state has established and established in current legislation mandatory safety parameters for this type of products, special sanitary and veterinary measures and requirements for both products and their producers, establishment of uniform standards safety, uniform systems of certification and marking, state control and supervision of the fulfillment of requirements and standards of environmental safety in the production and sale of agricultural products, as well as establishing norms of administrative, criminal, and civil liability for their violation. The main goals of state regulation of the agricultural sector are: guaranteeing the food security of the state; providing the population with quality food products; providing industry with raw materials; solving the problems of the economic and social nature of the development of the agricultural industry; ensuring the investment attractiveness of the agricultural sector; increasing the export potential of the agricultural sector.

Abstract:
Demand for nickel is constantly growing due to the versatility of its application, at the first place for stainless steel production. Ore reserves and possibility of nickel production of today’s Serbia and in neighboring countries were thoroughly investigated, and presented work is part of a wider project of sublimation of scientific and professional experience in the field of nickel extractive metallurgy on domestic raw materials. Presented research explores the possibility of high pressure sulfuric acid leaching of Serbian lateritic ores from localities Rudjinci, Ba and Lipovac. All three investigated ore deposits behaved differently both during preparation and during hydrometallurgical treatment. As optimal method for ore preparation proved to be crushing-milling-sieving route, but without possibility of concentrate production. Only for Rudjinci ore deposit achieved leaching efficiency reached satisfactory level of 95%. Within presented paper flow-sheet is proposed for processing high-magnesium laterite ores, with iron and magnesium oxide Both could be recirculated and used again in technological process; MgO for iron precipitation and SO2 for production of leaching agent, sulfuric acid. Final decision on the sustainability of the process will be made according to techno-economic and environmental evaluation. Estimated overall impact of the project implementation on the environment is negative.

Abstract:
Abstract The relationship between nutrition, production and environmental aspects of ruminant livestock production systems is a complex and highly nuanced subject that has long suffered from oversimplification and assumptions associated within these practices. However, with the advent of new and evolving models and a growing understanding of these complexities and their interactions with each other, there has been a large and welcome growth in recent literature regarding new and emerging technologies, and insights that will allow for appropriate and impactful changes in livestock management that will affect overall change for the benefit of society as a whole. The primary means through which environmental impacts may be modified are separated into four distinct, but interconnected mechanisms, which include 1) improvements in use of dietary nutrients, 2) use of dietary additives that impact certain functions in the digestive tracts of the animal, 3) improvements in genetics, and 4) improvements in productive efficiency. While it is obvious that there are significant overlaps between these practices, it is imperative to consider all these aspects to prevent “leakage” of impacts to other industries and processes. In this presentation, we will review recent developments in all of these areas with a specific emphasis on the use of energy in ruminant production systems.

Abstract:
The theoretical and practical directions of development of ecological agriculture in the country are justified, based on the idea of closed cycle, which corresponds to ecological and economic principles. The works of domestic and foreign scientists on this issue were studied. The main economic indicators of agricultural production on the example of Pavlodar region were analyzed: dynamics of gross output of agricultural sector; the number of operating agricultural enterprises and peasant (private) farms; distribution of the land fund by land categories. Information on violation of environmental legislation in the field of land resources protection and on the volume of waste in the industry is provided. The problems that hinder the implementation of the main provisions of greening of production activities in agro-industrial complex are identified. Summarizing the arguments of domestic and foreign scientists, the need to develop and implement the mechanism of functioning of agricultural entities is shown, which is based on the use of secondary resources, implementation of which in the future will allow, using comprehensive analysis of the used technologies, to modernize the production capacities of processing enterprises, implementing the principle of minimizing waste, ensuring expansion of the market for environmenttally friendly products. Models of rational production are shown: outsourcing and in sourcing. Measures of public support for the use of environmental innovations, environmental insurance, public-private partnership instruments, strengthening control over compliance with the principles of rational environmental management, economic incentives for agricultural producers are proposed.

Abstract:
The floating production unit HLNG FPSO-1 has been evaluated with respect to its energy consumption and emissions to air, and improvement potentials within the same context have been suggested. The thesis describes theory of combustion of natural gas, emission calculations, energy consumption of compressors and theory of fuel gas consumption for gas turbines. A literature study of LNG processes suitable for offshore applications has also been included. The CO2 emissions from the HLNG FPSO-1 add up to about 6% of the CO2 emissions from the Norwegian oil and gas industry (2005), which is a noticeable amount. However the energy content in the LNG produced over one year from the FPSO-1 count for ca 35% of the yearly energy consumed related to oil and gas extraction on the Norwegian continental shelf. This illustrates that even though floating LNG production is energy intensive and the resulting amounts of greenhouse gas emissions (as CO2) are substantial, the LNG holds significant amounts of energy, which is a result of the 600-fold reduction in volume when the natural gas is liquefied. Two different availabilities of the topside processes FPSO-1 exist and are calculated by Det Norske Veritas. The lower availability is based on a no-flare philosophy, which is considered not to be relevant for the project in the further development. The reason for this is that a strict no-flaring philosophy is not desirable from an operational point of view, and that duplication of every equipment item which handles hydrocarbon streams is not a realistic design alternative. Therefore the higher availability which allows some flaring during normal production is used for all the suggested improvement potentials. Based on two different future oil prices (a high and low scenario), the value of the LNG produced, as well as the value of the additional LNG produced as a result of higher availability of the FPSO-1 are calculated. Two design changes of the LNG liquefaction process as a result of a lighter feed gas composition are described and discussed in the context of energy consumption and emissions to air. Both design changes have the possibility of saving more than 10 MW power in total. Also, the implications of eventual necessary compliance with the Equator Principles are discussed. The project may find that certain guidelines or philosophies given by institutions financing parts of the project must be followed (such as use of Best Available Technology), and should evaluate these eventual restrictions when financial institutions are selected for the project. The further development of the project with the goal of making the topside processes on the FPSO-1 as energy efficient as possible (thereby saving operational costs and reducing the impact on the environment), should evaluate the feasibility of implementing the design changes suggested in the thesis from a more extensive technical and economical point of view.

Abstract:
The scarcity of fossil fuel and its environmental impact have shifted the world focus on green innovations At a time when the use of fossil fuel means increasing energy scarcity and an environmental crisis in the world in which we live, we need green innovations now more than ever. Growing attention has been drawn to the use of biofuels, such as bioethanol and biodiesel, which have gradually come to make up part of the total energy supply. Uncertainties about the environmental and ecological aspects of the production and consumption of biofuel still exist despite its rapid development. A life cycle analysis (LCA) evaluates the two principal functional parameters 1) energy efficiency and 2) Greenhouse Gas (GHG) balance of different feedstocks for biodiesel production from the cradle to the grave. By accounting a life cycle analysis stage by stage, we can ascertain the change in GHG emissions and energy demand that result from the various uses of feedstocks for the production of biodiesel. In this thesis, various life cycle analysis models are reviewed and evaluated with emphasis on specific biofuels. Different LCA models depend on different LCA calculation under different situations, including GREET, LEM, SimaPro, etc. The software SimaPro was used to compare the life cycle GHG emissions and energy demand from conventional petroleum fuels and several hydro-processed renewable green diesels. A consistent methodology was used for selected fuel pathways to facilitate relatively equitable comparisons. The building of life cycle flow tree in SimaPro combined the input and output with an emphasis on the following stages 1) raw material farming and acquisition, 2)liquid fuel production, 3)transport, 4)refueling, 5)liquid fuel conversion to biodiesel and 6) end uses. Consistent impact assessment methods were chosen for simulation, equitable comparisons and comprehensive analysis of selected fuel pathways for the calculation of Global Warming Potential (GWP) and Cumulative Energy Demand (CED). However, the results of the entire lifetime estimates vary dramatically in production chains, which make it difficult to take a holistic view about energy intake and yields, economic costs and values, environmental impacts and their benefits. Apart from the diversity in system boundaries and life cycle inventories, a variance in terminologies and the limitations of interdisciplinary communication are the main factors that affect the quality of the results.

Abstract:
The concept of sustainable development is receiving a great deal of attention in industry. However, the operational processes for industrial environmental management are still at an early stage of development and despite the best efforts of operations management and environmental specialists a great many products and services continue to be unsustainable. This presents threats to society and risks for survival to manufacturers. The purpose of the Thesis is to accelerate environmental improvements through the uptake of Cleaner Production concepts by developing a methodology for guiding manufacturing enterprises. The tenets of the proposed methodology include: o oo Reliance on a strategic approach ooo Development of an implementation path similar to those used in introducing other major culture and technology changes ooo Culture and policy change are strategically generated from within manufacturing organisations Specifically, the main objectives of the Project are: 1. to invent a relatively easily implementable methodology for planning for sustainability for manufacturing enterprises of all sizes 2. to address the major industrial environmental management issues at all levels within the enterprise as one seamless process 3. to configure the methodology so that it may be incorporated into an existing body of knowledge, e.g., manufacturing management/manufacturing engineering 4. to minimise complexities by standardising key concepts and terminology The Thesis integrates Sustainability and Cleaner Production concepts, systems and technologies and performance indicators with a planning model to arrive at what has been termed as " the Strategy Development and Implementation with Cleaner Production" process. This solution addresses the key point of integrating Cleaner Production concepts ii with the manufacturing planning processes, but just as importantly, it also establishes the links between the steps from strategy initiation through to implementation, from the boardroom down to the factory floor. The main modules of the work are: o oo establishing relationships between strategic, business and manufacturing plans using the concepts of Sustainability, Eco-efficiency and Cleaner Production ooo development of links between planning and operations using the concepts of Industrial Ecology and Life Cycle Management ooo development of a classification system, referred to as a Cleaner Production toolkit, to promote optimum selection of hard and soft systems and technologies ooo development of appropriate Cleaner Production Indicators to complete the loop.

Abstract:
Thesis (MTech (Business Administration))--Cape Peninsula University of Technology, 2017.
This research study investigates how environmental tools such as Resource Efficiency and Cleaner Production (RECP) can contribute to sustaining and supporting economic growth in South Africa. Resource optimisation is crucial when considering the concept of sustainable development. It also contributes to addressing the challenges of global warming and climate change, which in turn threaten industrial growth and sustainability in the long term. The study places emphasis on the barriers that prevent industry from implementing RECP recommendations, and identifies opportunities that could potentially reposition businesses should they consider implementation. It also promotes other sustainability tools that are available through collaboration with international entities, and this could be of great benefit to the South African industry. Factors of unemployment and urbanisation restricts national growth to some degree, hence the study explores how RECP can contribute to job retention by introducing new resource optimisation methodologies for the manufacturing sector, Moreover, it examines the imbalance between the demand as well as limitations of these resources. Through the compilation of data collated from questionnaires completed by industry, government and civil society participants, this study looks at achieving a balance between environmental sustainability and growth. It also looks at aligning this balance with the integration of specific economic and environmental policies, which also includes social aspects. What comes through significantly in this research is the lack of awareness within industry in terms of RECP, as well as the importance of prioritising the uptake of environmental initiatives to ensure that industry is compliant with the stringent policies and legislation designed by government to drive the sustainability process. Consequently the study shows that communication between public and private sector, as well as the awareness raising and marketing of sustainability to consumers need to be improved. An analysis of the various government support mechanisms is conducted, in respect of how industry could potentially leverage growth and drive positive change within their businesses. In addition to RECP, emphasis is placed on other Sustainable Consumption and Production (SCP) initiatives and tools that could possibly entrench sustainable practices and help with their incorporation into their business strategies.

Abstract:
Around one third of the weight of food produced for human consumption is lost or wasted, and around a third of crop calories are lost to the food system during livestock production. Meanwhile, the global food system causes significant environmental impacts and around 800 million people are undernourished. This building block examines the following aspects of food loss and waste: mainstream definitions and alternative understandings, global statistics, and ‘hierarchies’ for prevention and treatment.

Full text
Abstract:
Southern Madagascar’s worst drought in 40 years had devastating cumulative effects on harvest and livelihoods. On top of this, frequent sandstorms and pest infestations have led to severe stress on vegetation triggering a drastic decline in rice, maize and cassava production. These environmental aspects, combined with a lack of livelihood diversification and ongoing poverty, the presence of cattle raiders and restrictive government decisions, have driven the population of southern Madagascar to acute food insecurity conditions. By December 2021, more than 1.6 million people were estimated to have been suffering high levels of food insecurity. This case is an example of how multiple, complex environmental and social factors can combine to trigger a profound crisis in a territory, where vulnerable groups, such as children under five, tend to be particularly affected. Environmental degradation, together with socioeconomic and political dynamics are leaving vulnerable people even more exposed to food crises with few livelihood options or safety nets to cope with disasters. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Southern Madagascar food insecurity through a forensic analysis of academic literature, media articles and expert interviews.

Full text
Abstract:
As is true for all crops, production of Citrus fruit is limited by traits whose characteristics are the products of many genes (i.e. cold hardiness). In order to modify these traits by marker aided selection or molecular genetic techniques, it is first necessary to map the relevant genes. Mapping of quantitative trait loci (QTLs) in perennial plants has been extremely difficult, requiring large numbers of mature plants. Production of suitable mapping populations has been inhibited by aspects of reproductive biology (e.g. incompatibility, apomixis) and delayed by juvenility. New approaches promise to overcome some of these obstacles. The overall objective of this project was to determine whether QTLs for environmental stress tolerance could be effectively mapped in the perennial crop Citrus, using an extensive linkage map consisting of various types of molecular markers. Specific objectives were to: 1) Produce a highly saturated genetic linkage map of Citrus by continuing to place molecular markers of several types on the map. 2) Exploiting recently developed technology and already characterized parental types, determine whether QTLs governing cold acclimation can be mapped using very young seedling populations. 3) Determine whether the same strategy can be transferred to a different situation by mapping QTLs influencing Na+ and C1- exclusion (likely components of salinity tolerance) in the already characterized cross and in new alternative crosses. 4) Construct a YAC library of the citrus genome for future mapping and cloning.

Full text
Abstract:
Various unicellular algae produce omega-3 (w3) very-long-chain polyunsaturated fatty acids (VLC-PUFA), which are rarely found in higher plants. In this research and other studies from our laboratories, it has been demonstrated that the marine unicellular alga Nannochloropsis (Eustigmatophyceae) can be used as a reliable and high quality source for the w3 VLC-PUFA eicosapentaenoic acid (EPA). This alga is widely used in mariculture systems as the primary component of the artificial food chain in fish larvae production, mainly due to its high EPA content. Furthermore, w3 fatty acids are essential for humans as dietary supplements and may have therapeutic benefits. The goal of this research proposal was to understand the physiological and biochemical mechanisms which regulate the synthesis and accumulation of glycerolipids enriched with w3 VLC-PUFA in Nannochloropsis. The results of our studies demonstrate various aspects of lipid synthesis and its regulation in the alga: 1. Variations in lipid class composition imposed by various environmental conditions were determined with special emphasis on the relative abundance of the molecular species of triacylglycerol (TAG) and monogalactosyl diacylglycerol (MGDG). 2. The relationships between the cellular content of major glycerolipids (TAG and MGDG) and the enzymes involved in their synthesis were studied. The results suggested the importance of UDP-galactose diacylglycerol galactosyl (UDGT) in regulation of the cellular level of MGDG. In a current effort we have purified UDGT several hundredfold from Nannochloropsis. It is our aim to purify this enzyme to near homogeneity and to produce antibodies against this enzyme in order to provide the tools for elucidation of the biochemical mechanisms that regulate this enzyme and carbon allocation into galactolipids. 3. Our in vitro and in vivo labeling studies indicated the possibility that phosphatidylcholine (PC) and phosphatidylethanolamine (PE) are associated with desaturation of the structural lipids, whereas shorter chain saturated fatty acids are more likely to be incorporated into TAG. 4. Isolation of several putative mutants of Nannochloropsis which appear to have different lipid and fatty acid compositions than the wild type; a mutant of a special importance that is devoid of EPA was fully characterized. In addition, we could demonstrate the feasibility of Nannochloropsis biomass production for aquaculture and human health: 1) We demonstrated in semi-industrial scale the feasibility of mass production of Nannochloropsis biomass in collaboration with the algae plant NBT in Eilat; 2) Nutritional studies verified the importance algal w3 fatty acids for the development of rats and demonstrated that Nannochloropsis biomass fed to pregnant and lactating rats can benefit their offspring.

Israel, Alvaro, and John Merrill. Production of Seed Stocks for Sustainable Tank Cultivation of the Red Edible Seaweed Porphyra. United States Department of Agriculture, 2006. http://dx.doi.org/10.32747/2006.7696527.bard.

Full text
Abstract:
Porphyra species (commonly known as ‘nori’ or ‘purple laver’) are edible red seaweeds rich in proteins, vitamins and other highly valued biogenic compounds. For years Porphyra has been cultured using seeded nets extended in the open sea, and its biomass consumed primarily in the Far East. While demands for international markets have increased steadily at an average of 20% per year, supplies are on the verge and not expected to meet future demands. Alternatively, land-based cultivation of seaweed has become attractive in the mariculture industry since (1) important growth parameters can be controlled, (2) is environmentally friendly and (3) perfectly matches with integrated aquaculture leading to sustainable, high quality products. During the last few years a tank cultivation technology for Porphyra has been developed at the Israeli institution. This technology is based on indoor production of asexual spores and their subsequent growth to 1-2 mm seedlings. The seedlings are then transferred to outdoor tanks and ponds when seawater temperatures drop to 20 °C, or below, and days become shorter during winter time. However, the current technology efficiently serves only about 100 m2 of ponds during one growth season. In order to produce seedlings in sufficient amounts, it is critical to address both technical and biological aspects of seedling production, securing optimal up-scale to commercial-size cultivation farms. We hypothesize that massive production of spores is related to thalli origin, thalli age and sporulation triggers, and that seedling survival and their subsequent growth potential is determined by the seawater quality and overall indoor growth conditions imposed. A series of bio-reactors were constructed and tested in which spore release and spore growth were separately studied. The main assessment criteria for optimal viability of the seedlings will be by determining their electron transport rate using PAM fluorometry and by subsequent growth and biomass yields in outdoor ponds. Altogether the project showed (1), controlled sporulation is possible in big outdoor/growth chamber settings provided initial stock material (small frozen seedlings) is at hand, (2), contamination problems can be almost completely avoided if stock material is properly handled (clean as possible and partially dehydrated prior to freezing), (3), spore release can significantly be enhance using high nutrient levels during thawing for P. yezoensis and P. haitanensis, but not for P. rosengurttii, (4), PAM fluorometry is an efficient tool to estimate growth capacity in both seedlings and juvenile thalli. The BARD funding also served to explore other aspects of Porphyra biology and cultivation. For example, the taxonomical status of Porphyra strains used in this study was defined (see appendix), and the potential use of this seaweed in bioremediation was well substantiated. In addition, BARD funding supported a number of opportunities and activities in the Israeli lab, direct or indirectly related to the initial objectives of the project such as: additional molecular work in other seaweeds, description of at least 2 new species for the Israeli Mediterranean, and continuous support for the writing of a book on Global Change and applied aspects of seaweeds. The technology for Porphyra cultivation in land-based ponds is readily available. This study corroborated previous know-how of Porphyra growth in tanks and ponds, and yet offers important improvements regarding seedling production and their handling for successful cultivation. This study supported various other activities opening additional important issues in the biology/cultivation/use of Porphyra and other seaweeds.

Kislev, Yoav, Ramon Lopez, and Ayal Kimhi. Intergenerational Transfers by Farmers under Different Institutional Environments. United States Department of Agriculture, April 1995. http://dx.doi.org/10.32747/1995.7604936.bard.

Full text
Abstract:
This research studies the issues of intergenerational transfers in general and farm succession in particular in two different institutional environments. One is the relatively unregulated farm sector in the United States, and the other is the heavily regulated family farms in Israeli moshavim. Most of the analysis is based on modern economic theory dealing with inheritance and other intergenerational issues. However, we start with two background studies. One is a review of the legal system affecting farm succession in the moshav, which, as we claim throughout the report, is of major importance to the question in hand. The second is an ethnographical study aimed at documenting various inheritance and succession practices in different moshavim. These two studies provide insight for most of the economic studies included here. The theoretical studies mostly deal with various aspects of two major decisions faced by farmers: who will succeed them on the farm, and when will succession take place. The first decision clearly depends on the institutional structure: for instance, Israeli farmers are limited to one successor while American farmers are not. The second decision can be taken in three stages: sharing farm work with the successor, sharing farm management, and eventually transferring the ownership. The occurrence and length of each stage depend on the first decision as well as on the institutional structure directly. The empirical studies are aimed at analyzing the practices and considerations of Israeli and American farmers regarding various intergenerational transfers-related issues. We found that American farmers' decisions are mainly driven by the desire to let the farm prosper in future generations and by a preference for equal treatment of heirs, and not at all by old-age support considerations. In contrast, we demonstrate the significant effect of old-age support on the value of the transferred farm in a sample of Israeli farms. Using Israeli census data, we find that the time of farm ownership transfer responds to economic incentives. A smaller Israeli panel data set shows that controlling for the occurrence of succession, farm size rises with operator's age and eventually falls, while intensity of production seems to decline steadily. This explains another finding, that farm transfer contributed significantly to farm growth when farming was attractive to successors. This finding supports our main conclusion, that the succession decisions are of major importance to the viability and profitability of family farms over the long run.

Abstract:
To reduce financial risk and N losses to the environment, fertilization methods are needed that improve NUE and increase the quality of wheat. In the literature, ample attention is given to grid-based and zone-based soil testing to determine the soil N available early in the growing season. Plus, information is available on in-season N topdressing applications as a means of improving GPC. However, the vast majority of research has focused on wheat that is grown under N limiting conditions in sub-humid regions and irrigated fields. Less attention has been given to wheat in dryland that is water limited. The objectives of this study were to: (1) determine accuracy in determining GPC of HRSW in Israel and SWWW in Oregon using on-combine optical sensors under field conditions; (2) develop a quantitative relationship between image spectral reflectance and effective crop physiological parameters; (3) develop an operational precision N management procedure that combines variable-rate N recommendations at planting as derived from maps of grain yield, GPC, and test weight; and at mid-season as derived from quantitative relationships, remote sensing, and the DSS; and (4) address the economic and technology-transfer aspects of producers’ needs. Results from the research suggest that optical sensing and the DSS can be used for estimating the N status of dryland wheat and deciding whether additional N is needed to improve GPC. Significant findings include: 1. In-line NIR reflectance spectroscopy can be used to rapidly and accurately (SEP <5.0 mg g⁻¹) measure GPC of a grain stream conveyed by an auger. 2. On-combine NIR spectroscopy can be used to accurately estimate (R² < 0.88) grain test weight across fields. 3. Precision N management based on N removal increases GPC, grain yield, and profitability in rainfed wheat. 4. Hyperspectral SI and partial least squares (PLS) models have excellent potential for estimation of biomass, and water and N contents of wheat. 5. A novel heading index can be used to monitor spike emergence of wheat with classification accuracy between 53 and 83%. 6. Index MCARI/MTVI2 promises to improve remote sensing of wheat N status where water- not soil N fertility, is the main driver of plant growth. Important features include: (a) computable from commercial aerospace imagery that include the red edge waveband, (b) sensitive to Chl and resistant to variation in crop biomass, and (c) accommodates variation in soil reflectance. Findings #1 and #2 above enable growers to further implement an efficient, low cost PNM approach using commercially available on-combine optical sensors. Finding #3 suggests that profit opportunities may exist from PNM based on information from on-combine sensing and aerospace remote sensing. Finding #4, with its emphasis on data retrieval and accuracy, enhances the potential usefulness of a DSS as a tool for field crop management. Finding #5 enables land managers to use a DSS to ascertain at mid-season whether a wheat crop should be harvested for grain or forage. Finding #6a expands potential commercial opportunities of MS imagery and thus has special importance to a majority of aerospace imaging firms specializing in the acquisition and utilization of these data. Finding #6b on index MCARI/MVTI2 has great potential to expand use of ground-based sensing and in-season N management to millions of hectares of land in semiarid environments where water- not N, is the main determinant of grain yield. Finding #6c demonstrates that MCARI/MTVI2 may alleviate the requirement of multiple N-rich reference strips to account for soil differences within farm fields. This simplicity will be less demanding of grower resources, promising substantially greater acceptance of sensing technologies for in-season N management.

Full text
Abstract:
Time Domain Reflectometry (TDR) and other in-situ and remote sensing dielectric methods for determining the soil water content had become standard in both research and practice in the last two decades. Limitations of existing dielectric methods in some soils, and introduction of new agricultural measurement devices or approaches based on soil dielectric properties mandate improved understanding of the relationship between the measured effective permittivity (dielectric constant) and the soil water content. Mounting evidence indicates that consideration must be given not only to the volume fractions of soil constituents, as most mixing models assume, but also to soil attributes and ambient temperature in order to reduce errors in interpreting measured effective permittivities. The major objective of the present research project was to investigate the effects of the soil geometrical attributes and interfacial processes (bound water) on the effective permittivity of the soil, and to develop a theoretical frame for improved, soil-specific effective permittivity- water content calibration curves, which are based on easily attainable soil properties. After initializing the experimental investigation of the effective permittivity - water content relationship, we realized that the first step for water content determination by the Time Domain Reflectometry (TDR) method, namely, the TDR measurement of the soil effective permittivity still requires standardization and improvement, and we also made more efforts than originally planned towards this objective. The findings of the BARD project, related to these two consequential steps involved in TDR measurement of the soil water content, are expected to improve the accuracy of soil water content determination by existing in-situ and remote sensing dielectric methods and to help evaluate new water content sensors based on soil electrical properties. A more precise water content determination is expected to result in reduced irrigation levels, a matter which is beneficial first to American and Israeli farmers, and also to hydrologists and environmentalists dealing with production and assessment of contamination hazards of this progressively more precious natural resource. The improved understanding of the way the soil geometrical attributes affect its effective permittivity is expected to contribute to our understanding and predicting capability of other, related soil transport properties such as electrical and thermal conductivity, and diffusion coefficients of solutes and gas molecules. In addition, to the originally planned research activities we also investigated other related problems and made many contributions of short and longer terms benefits. These efforts include: Developing a method and a special TDR probe for using TDR systems to determine also the soil's matric potential; Developing a methodology for utilizing the thermodielectric effect, namely, the variation of the soil's effective permittivity with temperature, to evaluate its specific surface area; Developing a simple method for characterizing particle shape by measuring the repose angle of a granular material avalanching in water; Measurements and characterization of the pore scale, saturation degree - dependent anisotropy factor for electrical and hydraulic conductivities; Studying the dielectric properties of cereal grains towards improved determination of their water content. A reliable evaluation of the soil textural attributes (e.g. the specific surface area mentioned above) and its water content is essential for intensive irrigation and fertilization processes and within extensive precision agriculture management. The findings of the present research project are expected to improve the determination of cereal grain water content by on-line dielectric methods. A precise evaluation of grain water content is essential for pricing and evaluation of drying-before-storage requirements, issues involving energy savings and commercial aspects of major economic importance to the American agriculture. The results and methodologies developed within the above mentioned side studies are expected to be beneficial to also other industrial and environmental practices requiring the water content determination and characterization of granular materials.

Full text
Abstract:
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of a severe inflammatory bowel disease (IBD) in ruminants, known as Johne’s disease or paratuberculosis. Johne’s disease is considered to be one of the most serious diseases affecting dairy cattle both in Israel and worldwide. Heavy economic losses are incurred by dairy farmers due to the severe effect of subclinical infection on milk production, fertility, lower disease resistance and early culling. Its influence in the United States alone is staggering, causing an estimated loss of $1.5 billion to the agriculture industry every year. Isolation of MAP from intestinal tissue and blood of Crohn's patients has lead to concern that it plays a potential pathogenic role in promoting human IDB including Crohn’s disease. There is great concern following the identification of the organism in animal products and shedding of the organism to the environment by subclinically infected animals. Little is known about the molecular basis for MAP virulence. The goal of the original proposed research was to identify MAP genes that are required for the critical stage of initial infection and colonization of ruminants’ intestine by MAP. We proposed to develop and use signature tag mutagenesis (STM) screen to find MAP genes that are specifically required for survival in ruminants upon experimental infection. This research projected was approved as one-year feasibility study to prove the ability of the research team to establish the animal model for mutant screening and alternative in-vitro cell systems. In Israel, neonatal goat kids were repeatedly inoculated with either one of the following organisms; MAP K-10 strain and three transposon mutants of K-10 which were produced and screened by the US PI. Six months after the commencement of inoculation we have necropsied the goats and taken multiple tissue samples from the jejunum, ileum and mesenteric lymph nodes. Both PCR and histopathology analysis indicated on efficient MAP colonization of all the inoculated animals. We have established several systems in the Israeli PI’s laboratory; these include using IS900 PCR for the identification of MAP and using HSP65-based PCR for the differentiation between MAV and MAP. We used Southern blot analysis for the differentiation among transposon mutants of K-10. In addition the Israeli PI has set up a panel of in-vitro screening systems for MAP mutants. These include assays to test adhesion, phagocytosis and survival of MAP to/within macrophages, assays that determine the rate of MAPinduced apoptosis of macrophages and MAP-induced NO production by macrophages, and assays testing the interference with T cell ã Interferon production and T cell proliferation by MAP infected macrophages (macrophage studies were done in BoMac and RAW cell lines, mouse peritoneal macrophages and bovine peripheral blood monocytes derived macrophages, respectively). All partners involved in this project feel that we are currently on track with this novel, highly challenging and ambitious research project. We have managed to establish the above described research systems that will clearly enable us to achieve the original proposed scientific objectives. We have proven ourselves as excellent collaborative groups with very high levels of complementary expertise. The Israeli groups were very fortunate to work with the US group and in a very short time period to master numerous techniques in the field of Mycobacterium research. The Israeli group has proven its ability to run this complicated animal model. This research, if continued, may elucidate new and basic aspects related to the pathogenesis MAP. In addition the work may identify new targets for vaccine and drug development. Considering the possibility that MAP might be a cause of human Crohn’s disease, better understanding of virulence mechanisms of this organism might also be of public health interest as well.
