Available in PDF, EPUB and Kindle. Book excerpt: Nutrients from livestock & poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm & per acre have increased the risk of water pollution. New Clean Water Act regulations compel the large confined animal producers to meet nutrient application standards when applying manure to the land, & USDA encourages all animal feeding operations to do the same. The additional costs for managing manure (such as hauling manure off the farm) have implications for feedgrain producers & consumers as well. This report¿s farm level analysis examines onfarm technical choice & producer costs across major U.S. production areas for hauling manure to the minimum amount of land needed to assimilate manure nutrients.

Book excerpt: This volume compiles state-of-the-art scientific knowledge on the technologies that are used to quantify and reduce the environmental impact of livestock production in the cattle, pig and poultry industries. It makes a serious statement about how such technology can contribute to the sustainability of the livestock industry in the future. As the global livestock sector is growing, modern farm animal production is increasingly regarded as a source of solid, liquid, gaseous and dust emissions, which can be both nuisance and environmentally harmful. In light of hardening regulations and social pressure, there is increasing interest in scientific research on air pollution and emissions from livestock operations. The present chapters focus on methodology improvement, harmonization of measurements, and modeling aspects. Key aspects, such as renewable energy sources, nutritional approaches to reduce enteric methane emissions, technical options for manure management, and the use of sensors, are covered. By sharing good practices, this book is a valuable reference for a diverse readership. Experts across the veterinary and animal sciences, agricultural engineering, the food industry and sustainability research will benefit from the findings.

Book excerpt: Sustainability is a new, important discourse aimed at promoting a new strategy in the development of energy, water and environmental (EWE) systems OCo the key components that affect the quality of life on our planet. It is becoming increasingly clear that the quest for sustainable development requires integrating economic, social, cultural, political and ecological factors. The behavior and properties of an EWE system arise not merely from the properties of its component elements, but also to a large degree also from the nature and intensity of their dynamic interlinkages. This volume helps clarify the complexity of these problems by providing a deeper understanding of the implications of the different aspects of sustainability. This work contains a collection of selected, peer-reviewed and state-of-the-art reflecting papers that were presented at the Third Dubrovnik Conference on Sustainable Development of Energy, Water and Environment Systems that was held in June 5OCo10, 2005 in Dubrovnik, Croatia."

Book excerpt: This publication examines the risks associated with the release of excessive nitrogen into the environment (climate change, depletion of the ozone layer, air pollution, water pollution, loss of biodiversity, deterioration of soil quality). The report also examines the uncertainty associated with the ability of nitrogen to move from one ecosystem to another and cause "cascading effects". In addition to better management of nitrogen risks at the local level, there is a need to consider the global risks associated with the continued increase in nitrous oxide concentrations and to prevent excess nitrogen in all its forms by developing cost-effective strategies for all its sources. Other than the reduction of nitrogen pollution, this report provides guidance on the use of nitrogen policy instruments and how to ensure coherence with objectives such as food security, energy security and environmental objectives.

Available in PDF, EPUB and Kindle. Book excerpt: About 5% of all U.S. cropland is currently fertilized with livestock manure. Expanded environmental regulation through nutrient management plans will likely lead to wider use of manure on cropland, at higher production costs, but with only modest impacts on commodity demand, or farm structure. While current use is limited, expanded gov¿t. support could lead to a substantial increase in manure use as a feedstock. However, current energy processes are unlikely to compete with fertilizer uses of manure, because they leave fertilizer nutrients as residues, in more marketable form, and because manure-to-energy projects will be most profitable in regions where raw manure is in excess supply, with the least value as fertilizer.

Available in PDF, EPUB and Kindle. Book excerpt: Adequate and balanced crop nutrition – with nitrogen (N), phosphorus (P), and potassium (K) – is vital for sustainable crop production. Inadequate and imbalanced crop nutrition contributes to the crop yield gaps – a difference in actual and potential crop yield. Yield gap is one of the many causes of insufficient food production, thus aggravating hunger and malnourishment across the globe. On the other hand, an oversupply of nutrients is highly unsustainable, in terms of both resource conservation and global environmental health. A decreasing excreta recycling in crop production is one of the many reasons for nutrient imbalances in agriculture. Previous studies show that increasing agricultural specialization leads to spatial separation of crop and animal production. Increasing distance between excreta production and crop needs is one of the leading factors that cause reduced excreta recycling. Studies focusing on excreta recycling show that a substantial barrier to a more efficient excreta nutrient reuse is the expensive transportation of bulky volumes of excreta over long distances. In order to overcome that barrier, more detailed spatial estimates of distances between excreta production and crop nutrient needs, and the associated costs for complete excreta transport in an entire country are needed. Hence, the overall aim of this thesis was to quantify the amount of nutrients in the excreta resources compared to the crop nutrient needs at multiple scales (global, national, subnational, and local), and to analyze the need for excreta transports, total distances and costs, to meet the crop nutrient needs in a country. On the global scale, annual (2000-2016) excreta supply (livestock and human) could provide at least 48% of N, 57% of P, and 81% of K crop needs. Although excreta supply was not enough to cover the annual crop nutrient needs at the global scale, at least 29 countries for N, 41 for P, and 71 for K had an excreta nutrient surplus. When including the annual use of synthetic fertilizers, at least 42 additional countries had a N surplus, with the equivalent figures for P being 17 countries, whereas 8 additional countries attained a K surplus. At the same time, when accounting for the use of synthetic fertilizers, each year, at least 57 countries had an N deficit, 70 a P deficit, and 51 countries a K deficit, in total equivalent to 14% of global N and 16% of each P and K crop needs. The total surplus in other countries during the period was always higher than the deficit in the countries with net nutrient deficits, except for P for some years. Unfortunately, both the deficits of the deficit countries and surpluses of the surplus countries were increasing substantially during the 17 years. Such global divergence in nutrient deficits and surpluses have clear implications for global food security and environmental health. A district-scale investigation of Pakistan showed that the country had a national deficit of 0.62 million tons of P and 0.59 million tons of K, but an oversupply of N. The spatial separation was not significant at this resolution; only 6% of the excreta N supply needed to be transported between districts. Recycling all excreta, within and between districts, could cut the use of synthetic N to 43% of its current use and eliminate the need for synthetic K, but there would be an additional need of 0.28 million tons of synthetic P to meet the crop nutrient needs in the entire country. The need for synthetic fertilizers to supplement the recycled excreta nutrients would cost USD 2.77 billion. However, it might not be prohibitively expensive to correct for P deficiencies because of the savings on the costs of synthetic N, and K. Excreta recycling could promote balanced crop nutrition at the national scale in Pakistan, which in turn could eliminate the nutrient-related crop yield gaps in the country. The municipal-scale investigation using Swedish data showed that the country had a national oversupply of 110,000 tons of N, 6,000 tons of P, and 76,000 tons of K. Excreta could provide up to 75% of N and 81% of P, and more than 100% of the K crop needs in the country. The spatial separation was pronounced at the municipal scale in the country. Just 40% of the municipalities produced over 50% of the excreta N and P. Nutrient balance calculations showed that excreta recycling within municipalities could provide 63% of the P crop needs. Another 18% of the P crop needs must be transported from surplus municipalities to deficit municipalities. Nationally, an optimized reallocation of surplus excreta P towards the P deficit municipalities would cost USD 192 million for a total of 24,079 km truck transports. The cost was 3.7 times more than the total NPK fertilizer value transported, and that met the crop nutrient needs. It was concluded that Sweden could potentially reduce its dependence on synthetic fertilizers, but to cover the costs of an improved excreta reuse would require valuing the additional benefits of recycling. An investigation was also done to understand the effect of the input data resolution on the results (transport needs and distances) from a model to optimize excreta redistribution. The results showed that the need for excreta transports, distances, and spatial patterns of the excreta transports changed. Increasing resolution of the spatial data, from political boundaries in Sweden and Pakistan to 0.083 decimal grids (approximately 10 km by 10 km at the equator), showed that transport needs for excreta-N increased by 12% in Pakistan, and the transport needs for excreta-P increased by 14% in Sweden. The effect of the increased resolution on transport analysis showed inconsistency in terms of the excreta total nutrient transportation distance; the average distance decreased by 67% (to 44 km) in Pakistan but increased by 1 km in Sweden. A further increase in the data resolution to 5 km by 5 km grids for Sweden showed that the average transportation distance decreased by 9 km. In both countries, increasing input data resolution resulted in a more favorable cost to fertilizer value ratios. In Pakistan, the cost of transport was only 13% of the NPK fertilizer value transported at a higher resolution. In Sweden, the costs decreased from 3.7 (at the political resolution) to slightly higher than three times of the fertilizer value transported in excreta at the higher data resolution. This Ph.D. thesis shows that we could potentially reduce the total use of synthetic fertilizers in the world and still reduce the yield gaps if we can create a more efficient recycling of nutrients both within and between countries, and a more demand adapted use of synthetic fertilizers. Livsmedelsproduktion är grunden för vårt samhälle idag och för den utveckling som skett det senaste århundrandet. Idag är vi åtta miljarder människor i världen med en produktion och handel med livsmedel, där knappt en miljard lever under hunger och svält. Inom de närmaste decennierna förväntas världens befolkning fortsätta växa och stanna av på omkring 11 till 12 miljarder människor under senare hälften av 2000-talet. För att klara livsmedelsförsörjningen bättre idag, och ännu mer så i framtiden, krävs att vi hittar former för att återföra skördade näringsämnen, som fosfor, kväve och kalium, tillbaka till åkermarken. Många av dessa näringsämnen är ändliga resurser som dessutom bidrar till övergödning om de läcker ut till andra habitat. I dag återfinns det mesta av dessa näringsämnen i gödsel, mänsklig exkreta och rötslam från avloppsreningsverk. Avhandlingen har studerat förutsättningarna för att sluta en större del av näringsämnens cykler i Sverige och Pakistan genom återföring av gödsel och mänsklig exkreta till jordbruksmark, samt utifrån detta även dragit slutsatser om de globala förutsättningar och effekterna av att sluta kretslopp för näringsämnen. Effekterna av att förbättra återförsel av näringsämnen till åkermark innefattar en minskad belastning i miljön som resultat av minskad användning av handelsgödsel, minskad användning av energi för produktion av handelsgödsel, samt framför allt ökade möjligheter för en långsiktigt hållbar hög skörd på åkerarealen. Det finns dock energikostnader vid återförsel av näringsämnen till följd av många och tunga transporter. Avhandlingen har därför analyserat transportkostnader för effektiv återvinning av näringsämnen från djurhållning och mänsklig exkreta och hur stor del av gödselbehovet som kan täckas av dessa återförda näringsämnen. Speciellt har avhandlingen också studerat hur viktigt det är att ta hänsyn till i vilken skala man skall studera problemet, dvs om det är data på gödselbehov och tillgång som är lokala - ända ner på enskilda fält och gårdar - regionala eller nationella som man skall utgå från när man söker efter effektiva lösningar för att sluta näringsämnes cykler. Resultaten visar att större delen av gödselbehovet i både Pakistan och Sverige kan täckas genom återvinning av stallgödsel och mänsklig exkreta. I Sverige kan 81% av fosforbehovet täckas på det viset. Transporterna sker i första hand inom kommuner, 63% av behovet, medan de resterande 18% av behovet som kan täckas kräver transporter som är längre och sker mellan kommuner. Kostnaden för transporterna är däremot höga och motsvarar mer än tre gånger kostnaden för motsvarande handelsgödsel. I Pakistan är kostnadsbilden annorlunda, bl.a. eftersom lönekostnaderna är lägre och handelsgödsel är dyrare än i Sverige. Avhandlingen visar att kostnaden för transporter av gödsel i Pakistan skulle motsvara enbart 13% av kostnaden för motsvarande mängd handelsgödsel. Det mesta av återförandet av näringsämnen sker inom distrikt, till exempel är det bara 6% av kvävebehovet som behöver täckas av transporter utanför distrikten. Pakistans handelsgödselanvändning, och därmed kostnad för detta, skulle vid en effektiv återvinning av näringsämnen kunna reduceras ned till 43% av dagens kostnader för kvävegödsel, för fosfor behövs det 0.28 miljoner ton och behovet av kaliumgödsling skulle helt försvinna. Det krävs därmed handelsgödsel motsvarande 2.77 miljarder USD, vilket till del skulle kunna kompenseras av minskade totala kostnader för kväve- och kaliumgödsel. En sådan återföring av näringsämnen i Pakistan skulle också medföra en högre gödseltillförsel till jordbruket och därmed en möjlighet att reducera skördegapet i landet. Skördegapet i Pakistan är betydande med veteskördar kring 25–30% av de möjliga, och dessa skördegap anses bero just på för små gödselgivor. Pakistan har också tydliga problem med livsmedelsförsörjning på grund av dagens skördegap med 20% av en befolkning på 200 miljoner som är undernärda. För Sveriges del är produktionen och avkastningen per areal till följd av gödsling redan hög. En mer effektiv återförsel av näringsämnen i Sverige skulle därför i första hand bidra till att minska användning av handelsgödsel och därmed begränsa användning av ändliga resurser som fosfor. Analyserna i avhandlingen visar till exempel att i Sverige skulle användning av fosfor som handelsgödsel kunna minska med 67% om återförsel av stallgödsel och mänsklig exkreta effektiviserades. Analyser av globala data för år 2000 – 2016 visar att den årliga tillgången på näring i gödsel (från djur och människor) motsvarar minst 48% av grödornas N behov, 57% av P behovet och 81% av K behovet. Även om den total mängden näring i stallgödsel och mänsklig exkreta inte räcker för att täcka det årliga globala behovet av näring, så visar data på ett överskott på N i minst 29 länder, ett överskott på P i minst 41 länder och 71 länder har ett K-överskott i stallgödsel och exkreta. Om man dessutom räknar in användningen av handelsgödsel blir det ytterligare 42 länder som har överskott på N, 17 länder till med P-överskott och 8 ytterligare med K-överskott. En stor del av resterande länder har ett underskott av näringsämnen (när man summerar gödsel, mänsklig exkreta och handelsgödsel), 57 länder har brist på N, 70 länder behöver mer P och 51 har brist på K i sitt jordbruk, och har därmed lägre skördar än möjligt. Det totala överskottet av näringsämnen i de andra länderna under denna period motsvarar dock rätt väl den brist som länder med underskott uppvisar. Tyvärr är trenden den att de länder som visade på överskott av näringsämnen år 2000 har sammantaget tydligt ökat på överskottet till 2016, medan även underskotten har ökat i flera av länderna med bristande tillförsel av N, P eller K. Sådana globala obalanser har tydliga implikationer för den framtida matförsörjningen och för miljön. Avhandlingen visar att vi idag skulle kunna använda mindre handelsgödsel totalt i världen, och ändå reducera de skördegap som finns, om vi skapar en effektiv återförsel av näringsämnen såväl inom som mellan länder och ett mer behovsanpassat användande av handelsgödsel.

This book was released on 2015-03-09 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: From leading ecology advocates, a revealing look at our dependence on cows and a passionate appeal for sustainable living. In Cowed, globally recognized environmentalists Denis and Gail Boyer Hayes offer a revealing analysis of how our beneficial, centuries-old relationship with bovines has evolved into one that now endangers us. Long ago, cows provided food and labor to settlers taming the wild frontier and helped the loggers, ranchers, and farmers who shaped the country’s landscape. Our society is built on the backs of bovines who indelibly stamped our culture, politics, and economics. But our national herd has doubled in size over the past hundred years to 93 million, with devastating consequences for the country’s soil and water. Our love affair with dairy and hamburgers doesn’t help either: eating one pound of beef produces a greater carbon footprint than burning a gallon of gasoline. Denis and Gail Hayes begin their story by tracing the co-evolution of cows and humans, starting with majestic horned aurochs, before taking us through the birth of today’s feedlot farms and the threat of mad cow disease. The authors show how cattle farming today has depleted America’s largest aquifer, created festering lagoons of animal waste, and drastically increased methane production. In their quest to find fresh solutions to our bovine problem, the authors take us to farms across the country from Vermont to Washington. They visit worm ranchers who compost cow waste, learn that feeding cows oregano yields surprising benefits, talk to sustainable farmers who care for their cows while contributing to their communities, and point toward a future in which we eat less, but better, beef. In a deeply researched, engagingly personal narrative, Denis and Gail Hayes provide a glimpse into what we can do now to provide a better future for cows, humans, and the world we inhabit. They show how our relationship with cows is part of the story of America itself.
