Effect of mulch on water use and productivity if wheat in Punjab, India: fiel...Joanna Hicks
This document summarizes a study on the effect of mulch on water use and productivity of wheat in Punjab, India through field experiments and crop modeling. The study found that:
1) In field experiments from 2006-2007 and 2007-2008, mulch reduced irrigation water requirements by 50-75 mm compared to no mulch, while maintaining similar grain yields and biomass production.
2) Modeling results using the APSIM crop model validated well against field data and showed that mulch increased the probability of obtaining grain yields over 7 t/ha in 60% of years by reducing water stress.
3) Both field and modeling results demonstrated that mulch improved water productivity by maintaining productivity with lower irrigation
This document discusses breeding cattle for lower greenhouse gas emissions in Australia. It found that there is natural variation in methane yield between bulls, with some being high and some being low methane yield. Selective breeding using low methane yield bulls could reduce cumulative enteric methane emissions from cattle by over 568,000 tons over 25 years. Adding a breeding value for low methane yield to selection indexes may help lower greenhouse gas emissions from cattle herds in a quantifiable and verifiable way.
1) Total storage capacity in the Murray-Darling Basin (MDB) has increased to 1.5 times the average annual flow of all rivers in the basin between 1920-2010 due to increased development of major storages and farm dams.
2) Dairy production accounts for 20% of the gross value of production but uses 17% of water in the MDB, while cotton accounts for 17% of value but uses 20% of water.
3) Recent climate trends in the MDB show a decrease in the number of wet months per year and an intensification of drought conditions linked to global warming.
The document discusses the concept of transformational adaptation to climate change in the context of agriculture. It provides examples of transformational changes in agriculture over time brought on by various drivers such as climate and market forces. The document also outlines different perspectives on transformational change and the potential roles that science and government can play in supporting rather than directing transformation.
This document discusses a project examining how the Australian forestry industry has adapted to recurrent droughts and whether these experiences can inform future climate change adaptation. It summarizes that the region has experienced both a long-term drying trend and severe droughts that have negatively impacted forests. The industry responded by improving site selection, species matching to climate, and soil water management. It questions whether current institutions and research capabilities will allow continued adaptation to future climate changes and uncertainties.
Climate change presents both specific and generic challenges for marine biodiversity and fisheries. A portfolio approach is needed to manage these challenges as the issues have multiple drivers and require multifaceted solutions. Information related to climate change impacts must also be addressed synergistically. Quality climate change science is important to inform policy in this confused policy area. Both attribution of impacts and understanding variability, extremes, interactions and feedbacks are major scientific challenges.

This document discusses greenhouse gas emissions from soils and the implications of climate change. It summarizes the processes that generate and consume carbon dioxide, nitrous oxide, and methane in soils. It examines the potential impacts of climate change on each greenhouse gas and possible mitigation options. The document outlines that climate change may increase soil carbon dioxide emissions through higher temperatures and altered rainfall patterns, and that nitrous oxide emissions are strongly influenced by temperature and water availability. Future research is needed to better understand these relationships and identify mitigation strategies.
The document discusses water sharing arrangements in NSW and challenges in accounting for climate variability and climate change. It outlines how water plans are developed using historical climate data but notes limitations in assuming climate stationarity. Modelling future climate poses issues around downscaling global models. The presentation argues for a risk-based approach using current knowledge while improving understanding of climate impacts over time.
The document discusses a study looking at ways to reduce nitrous oxide emissions from animal agriculture systems. The study focuses on emissions from urine patches in dairy grazing systems and tests the effectiveness of applying dicyandiamide (DCD) to pastures both immediately after and one month prior to applying urine from grazing animals. The results showed DCD reduced nitrous oxide emissions by 35-45% regardless of when it was applied relative to urine application. DCD's impact on emissions was found to last at least 90 days when applied in late winter or autumn. Whole paddock dry matter production was minimally affected by DCD application.
The document studied the effects of supplementing dairy cow feed with different doses of algae meal high in docosahexaenoic acid (DHA). It found that while supplementary DHA did not reduce the cows' methane emissions or decrease milk yield, it did lower milk fat percentage and yield by around 25%. However, the milk produced was enriched with healthy omega-3 fatty acids like DHA and EPA as well as conjugated linoleic acid and polyunsaturated fatty acids. Overall, supplementary DHA changed the cows' milk composition but did not achieve the goals of reducing emissions or maintaining production levels.
The document discusses projections for global population growth, food demand, and greenhouse gas emissions from agriculture between now and 2050. It finds that:
1) The world population is projected to grow from 6.1 billion in 2000 to over 9 billion by 2050, with most growth occurring in developing regions.
2) Global food production would need to increase by 70% to feed the additional 3 billion people.
3) Agricultural greenhouse gas emissions are projected to increase by 54% between 2000 and 2050 if no mitigation efforts are adopted. Reductions of up to 56% for methane and 26% for nitrous oxide may be possible with existing technologies.
The document discusses the concept of transformational adaptation to climate change in the context of agriculture. It provides examples of transformational changes in agriculture that have occurred historically in response to environmental changes. These include changes from sheep to beef production and adjustments to cropping regions. The document also examines the potential role of science in understanding and facilitating transformational adaptation through case studies, predictive research, and establishing policies and information to expand options and address risks. There are differing views on whether transformational change is seen as failure or as an opportunity in response to climate change.
The document discusses 5 big questions farmers should ask themselves about whether they are enjoying and can sustain their current farming practices. It also outlines 5 potential options for farmers to consider: 1) improving profitability, 2) changing their business structure, 3) changing enterprises, 4) changing their capital base, or 5) exiting farming. The author questions whether most resources encourage only incremental changes and whether more support is needed for transformational changes, given climate challenges.
The document summarizes research on managing grazing systems under climate change projections out to 2030. It discusses modeling the impacts of climate stress on livestock indicators like pasture growth and gross margins. It also examines potential adaptation strategies tested, like varying stocking rates and lambing/calving times. The research found climate change will negatively impact farm profits but that adaptations can help, and that flexibility and grazing management will be important for farmers to adapt.
1) The document discusses a project that evaluated the impacts of climate change on mixed crop-livestock farms in Tasmania and identified adaptation options and barriers.
2) Workshops were held in five regions of Tasmania to discuss how farmers currently manage climate variability and how they may need to adapt their practices in the future given projected changes.
3) The workshops found that farms in northern regions had greater adaptive capacity due to factors like irrigation, off-farm income, and social networks, while southern farms faced more constraints like lack of funds and rural decline.
The document discusses research on the impacts of elevated CO2 levels on wheat production in Australia. Key findings include:
- Wheat grown under elevated CO2 (550 ppm) at two sites in Australia showed yield increases of 22-61% depending on location and year. More stimulation was seen at the drier location.
- Elevated CO2 decreased grain protein levels by 4-13% but increased nitrogen uptake in straw and grains by 24-63%. This has implications for wheat quality and nitrogen management.
- Crop modeling found that despite experimental yield increases under elevated CO2, future changes in rainfall and temperature are predicted to result in yield losses of 10-20% in some regions and gains of 10
The document discusses the role of extension in enabling climate change adaptation. It argues extension should address broader questions like who adaptation benefits and its goals, rather than just focusing on solutions. It also stresses the need to consider direct, indirect and adaptation impacts of climate change, and ensure adaptation reduces vulnerability for all groups and contributes to social justice. The document suggests extension promote discussion of diverse perspectives and facilitate adaptation that leads to multiple co-benefits, including reduced climate change.
The document summarizes a study on the effects of rising CO2 concentration on the water use efficiency of Eucalyptus saligna trees. The study used whole tree chambers to expose trees to ambient (390 ppm) and elevated (630 ppm) CO2 levels, with half of each group also subjected to periodic drought. It found that trees exposed to elevated CO2 had much lower water loss but similar carbon uptake levels. This supported the Ball-Berry model that transpiration efficiency increases under elevated CO2 levels due to downregulation of stomatal conductance, with no acclimation of this response to CO2. The implications are that forest growth models may need updating to account for effects of CO2 and
The document discusses several issues related to ensuring global food security in a changing climate. It notes that climate change is projected to reduce wheat yields in India by around 6 million tons per year for every 1 degree Celsius rise in temperature. It emphasizes the need for more sustainable agricultural practices to mitigate climate change impacts and ensure long-term food production, including conservation farming, agroforestry, and community-based natural resource management approaches. The document also highlights several climate-resilient crops and varieties developed through plant breeding and biotechnology research.
Nitrous oxide emissions from soils are strongly linked to rainfall and soil moisture levels. Higher emissions were observed from canola plots that received urea fertilizer compared to chickpea plots. Emission factors for N2O were around 0.3-0.8% of applied nitrogen for canola and 0.3% for chickpea. Including more pulse crops in rotations has the potential to reduce N2O emissions from broadacre farming by decreasing fertilizer use and increasing nitrogen use efficiency.
1. White clover biomass and cyanide levels tended to increase, suggesting resources were diverted from protein production to cyanide defense.
2. The effect of elevated CO2 depended on nutrient availability - only with phosphorus addition did cyanide levels rise relative to protein.
3. Microbial symbionts like mycorrhizal fungi and nitrogen-fixing rhizobia that aid nutrient acquisition may also be impacted by elevated CO2, further influencing plant nutrition.
The document summarizes a conference on modeling N2O emissions from agricultural soils held from February 15-17, 2011 in Melbourne. It discusses processes contributing to and interacting with N2O production in soil, methods for measuring N2O fluxes, spatial and temporal variability of N2O emissions, and challenges in modeling N2O emissions from different crops and regions using process-based models like WNMM. Validation of key model outputs is important before validating N2O flux simulations. The model has been applied to study regional emissions from wheat cropping systems and irrigated pastures and sugarcane.
This document summarizes research analyzing changes in pasture production and growing seasons in three dairy regions of Southeast Australia over several decades. Biophysical models were used to simulate pasture growth rates based on definitions of growing season length and wet or dry conditions. The models accurately represented measured pasture growth rates. Historical analyses of the three regions from 1960 to 2008 found changes in the start and end dates of the growing seasons over time.
RIRDC is a government-industry partnership that funds rural industries research and development through a $27M budget. Its goals are to foster sustainable and profitable rural industries and increase understanding of national rural issues. Regarding climate change, RIRDC funds research into making rural industries more resilient to a changing climate through projects like developing new crops and pastures, harvesting pest species to reduce emissions, and improving efficiency and reducing emission practices. RIRDC is currently developing a new 5-year investment plan that will likely focus on further research related to climate change impacts and opportunities for rural industries.
The document models the impacts of climate change on wheat flowering times in the NSW wheat belt of Australia. It finds that under climate change, spring wheat flowering times will be shortened, especially with earlier sowing dates. Winter wheat flowering times will be shortened in cooler eastern regions and lengthened in warmer western regions. Heat stress risks for spring wheat increase with late sowing dates after 2070, though grain filling stress may decrease due to earlier flowering. For winter wheat, heat stress risks during flowering and grain filling increase in some northwestern regions after 2030. The document recommends adapting sowing dates, changing varieties, and breeding slower developing spring varieties.
Laurie Arthur, a rice farmer, is adapting their farm to climate change by exploring growing rice in Northern Australia to diversify from their southern farm that frequently experiences low water allocations. They have had some success trialling rice varieties in the Ord Valley in Northern Australia, which has higher security water rights. However, challenges remain in increasing yields, improving grain quality, and reducing costs to establish a viable northern rice industry at a large enough scale. The farmer aims to gradually expand rice production across both their northern and southern farms to manage climate change risks while not compromising the southern operation.

Water resources and biofuels water quality april 2012Sharon Lezberg
This document discusses water quality issues related to hypoxia. It begins by defining hypoxia as low dissolved oxygen concentrations that cannot support marine life, typically below 2 ppm. It then explains that hypoxia occurs due to algae blooms in freshwater settling on the bottom and consuming oxygen during decomposition. The size of hypoxic areas can be large, such as the size in 2008 shown on a map. Nutrient flux and sources of nitrogen and phosphorus that contribute to algae blooms and hypoxia are also discussed. The document considers future impacts on water quality from different cropping systems and biofuel production approaches.

Some of the unique features and benefits of GBP Eco Render that contribute to the lower cost include being ready to use, self-curing, shrinkage free, crack resistant, and producing zero wastage.
Beginning with the End in Mind: Rare Earths - Sept 2013 - Greenfields Researc...John Sykes
The document contains numerous charts and graphs related to rare earth elements projects and markets. It discusses factors such as project timelines, resource and reserve characteristics, processing recoveries and costs, and categorizes projects as "stars", "cash cows", "problem children" and other labels based on their market potential and investment requirements. It emphasizes the importance of high resource grade, large scale, and overall project economics in achieving success in the rare earth industry.
This document discusses water productivity, which is defined as the benefit gained per volume of water used. It outlines the rationale for increasing water productivity at various scales from global to individual water users. The document then describes the methodology for estimating water productivity simply as the ratio of gain to water use. It notes some progress made in measuring water productivity for different crops and livestock. However, it also discusses challenges in estimation due to uncertainties in measuring benefits and water consumption. Interpreting water productivity values is also difficult as it is a partial measure that does not account for all gains from agricultural systems.

1) Nitrous oxide emissions from agricultural soils are a major source of emissions in Australia, with fertilizer application being a key driver.
2) A study measured nitrous oxide emissions from wheat crops with different nitrogen sources and found significantly higher emissions when urea fertilizer was used compared to no fertilizer or a legume rotation.
3) Legume rotations supplied sufficient nitrogen for wheat growth in low rainfall years and generated less nitrous oxide emissions than urea fertilizer, though establishing legumes can be challenging in drier conditions.
The document summarizes research into the commercial viability of using dicyandiamide (DCD) on dairy farms in southwestern Victoria to reduce nitrous oxide emissions and increase pasture growth. Based on the results, using DCD is not currently economically feasible as the potential benefits of reduced emissions and increased dry matter production are not large enough to offset the costs of DCD application. For DCD use to be viable would require showing larger increases in pasture growth, higher fertilizer prices, lower DCD prices, or an emissions trading scheme with higher carbon prices. Further research is still needed.
The document summarizes a study examining how elevated carbon dioxide levels will impact grain production across different soil types. The study exposed wheat and field pea crops grown in three different Australian soil types to ambient and elevated (550 ppm) carbon dioxide levels. In the first year, there was no effect of elevated carbon dioxide on dry matter, nitrogen uptake, or grain yield. Soil type had a large impact on these variables. In the second year, elevated carbon dioxide and soil type interacted to impact plant growth and nitrogen uptake in field peas. The study also found elevated carbon dioxide and soil phosphorus levels interacted to influence root growth, nutrient uptake and distribution in pulses. The results indicate the effect of elevated carbon dioxide on nutrient
The study evaluated the impact of the nitrification inhibitor DMPP on nitrous oxide (N2O) emissions from a pasture in southwestern Victoria treated with urea fertilizer. When applied with urea, DMPP delayed the formation of nitrates, reduced cumulative net N2O emissions by 73% over 6 months, and increased dry matter production by 6% compared to urea alone. DMPP particularly reduced N2O emissions during periods of high rainfall and temperature by inhibiting the nitrification process. The results demonstrate that DMPP can significantly decrease N2O emissions from fertilized pastures while maintaining crop growth.
This document discusses the threats posed by fungal pathogens to global food security under a changing climate. It provides examples of how past epidemics like the Irish Potato Famine were exacerbated by wet and cool conditions. Current threats like wheat stem rust could cause major crop losses. Pulses like chickpeas grown in Australia are susceptible to diseases that are being influenced by more frequent extreme rainfall events linked to climate change. Effective management may require anticipating how farming practices need to adapt.
1) The study uses a farming systems model to compare the effects of improved agricultural management practices and predicted climate change on sugarcane yields and nitrogen loads in the Mackay-Whitsunday region.
2) Adopting best management practices (Class A) is found to significantly reduce nitrogen loads compared to conventional practices (Class D), with an effect much greater than any predicted climate change scenario.
3) While climate change may impact yields, moving to the best practices provides water quality improvements regardless of climate scenario due to large nitrogen load reductions.
Managing crop production uncertainties and climate variability though a map-based system. The document discusses how Bungulla Farming, which operates 7,200 hectares of cropping land in Australia, uses a map-based system to manage risks and increase productivity in the face of increasing input costs, volatile grain prices, and climate change impacts like decreasing rainfall. Key data layers like soil nutrients, climate records, water availability, and machinery operations are integrated into interactive farm maps to help make strategic decisions at critical points and increase nitrogen use efficiency and targeted weed control.
This project aims to demonstrate ways for wheat cropping systems in Western Australia to adapt to climate uncertainty through increased flexibility. Potential strategies discussed include:
1) Growing varieties with desirable stability/plasticity of yield components under varying conditions.
2) Strategically structuring plant populations using varietal mixtures to maximize buffering against stress.
3) Controlling populations by killing part of the crop later in the season if weather forecasts indicate dry and warm conditions to reduce yield loss.
This document summarizes a project that aims to help Australian farmers manage future agricultural production in a changing climate. The project brings together experts and farmers to discuss potential climate impacts and adaptation options. Farmers provide local knowledge of cropping systems while experts use crop modeling and simulations to evaluate adaptation strategies. The research shows that combining local expertise with modeling is needed to develop effective regional adaptations, as climate change impacts and solutions will vary locally. Adapting to significant climate change remains a challenge across Australia.
This document summarizes research on the potential for land use change in the Border Rivers-Gwydir Catchment region of Australia to mitigate greenhouse gas emissions through carbon sequestration. The research analyzed the carbon sequestration potential and costs of converting land to different uses like forests and environmental plantings. It found that mixed-species environmental plantings and Pinus radiata plantations have the highest carbon sequestration potential. However, targeting only regions with the highest sequestration may not be the lowest-cost strategy. The results are sensitive to the discount rate used in the analysis.
This document discusses agricultural adaptation to climate change. It notes that adaptation involves finding ways to deal with issues like less water and higher temperatures. Crop adaptation is the basis of agriculture and involves the relationship between environmental factors and plant growth. Climate risks go beyond individual farms and are linked through markets. Increasing uncertainty due to climate change affects available options and outcomes. The document examines factors like declining terms of trade and total factor productivity in Australian agriculture over time. It discusses challenges like path dependence and separating climate change from natural variability when making adaptation decisions.
1. The Future Farm Industries Cooperative Research Centre aims to develop profitable perennial pastures and farming systems to change the nature of farming, create new industries, and improve natural resource management in southern Australia.
2. The CRC conducts research and development with partners to increase productivity, develop new regional industries using woody crops, and reduce environmental degradation through perennials. It estimates monetary benefits of $808 million by 2021 and $2.51 billion by 2030 from adopting perennial systems.
3. An analysis of adopting new perennial pastures in Western Victoria found they can improve farm profitability through increased carrying capacity and returns on investment, but results depend on climate variability and supplementary feeding costs.
The document discusses how yield prophet and precision agriculture tools can help farmers in the North Agricultural Region of Western Australia better manage risk and increase productivity by accounting for significant seasonal production volatility and soil variability within fields. It provides examples of how yield prophet has accurately predicted yields when soils are well characterized and highlights the need for experienced operators and thorough soil testing to set up accurate soil zones and variable rate crop management.
This document summarizes research on using seasonal climate forecasts to inform nitrogen application strategies for wheat farming in order to maximize profits while minimizing risk. Simulations show that a forecast-informed conservative nitrogen management strategy can increase farm profits from $235K to $402K compared to no forecast. A moderately skillful forecast was found to pay for itself within 7 years with a 80% chance of paying off within 3 years. Adopting mixed farming practices and incorporating seasonal forecasts provides additional financial benefits for dealing with climate variability.
- The document discusses a climate change adaptation project in Southern NSW that engaged local farmers through case studies and surveys to understand their attitudes towards and preparation for climate change.
- Preliminary survey results found that farmers were uncertain about the impacts of climate change but many agreed that droughts would increase and temperatures would rise.
- While many farmers intended to stay committed to farming, they were open to adapting their practices like using more drought-tolerant crops or increasing water conservation.
The document discusses the projected impacts of climate change on pasture production in southern Australia. It summarizes climate projections showing increased temperatures and decreased rainfall by 2030, 2050, and 2070. It then describes how a modeling approach was used to explore the effects of these climate changes on annual pasture growth. The modeling indicated higher winter production but shorter springs under warmer and drier conditions. Finally, it recommends a focus on heat-tolerant and water-efficient species as adaptations to support resilient pasture systems into the future.
The document discusses conclusions from a previous study or analysis. In 3 sentences or less, it summarizes the key findings and outcomes of the research without providing unnecessary details. The summary captures the most important essence and implications of the conclusions.
This document summarizes a study examining how different adaptation policies for a sheep grazing system in southern Australia may perform under climate change. The study uses models to simulate the system under historical weather from 1970-2009 and projected future climates from 2010-2099. It finds that climate change impacts will not be masked by natural variability and that adaptation policies like incremental changes or those based on long-term forecasts may outperform traditional or step-change approaches. Inter-decadal variability is also an important source of uncertainty. The best policy depends on the specific climate scenario, and future work could blend incremental and forecast approaches while considering ensembles of climate projections.
1) The document summarizes research on how climate change may impact the financial risks and viability of dryland farms in three regions of Western Australia.
2) Bioeconomic modeling was used to simulate 20-year sequences for different farm characteristics and climates in each region.
3) The results found that farms with high debt, small size, low crop production, and livestock focus were most at risk of insolvency, especially in low rainfall regions under climate change. Larger farms with less debt and more crops/lambs were less at risk.
The document discusses restoring soil carbon and landscape function through regenerative farming practices like planned grazing. It notes that high intensity agriculture is heavily dependent on fossil fuels and external inputs, while complex plant communities require one third of absorbed solar energy to maintain themselves. Using holistic management and planned grazing techniques over many years has increased soil carbon, plant diversity, and resilience on the author's property in Australia. The document advocates changing human practices to collaborate more with natural systems rather than relying on technological fixes.

From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

• Residue retained soils in cane have sufficient C inputs to
produce of CH4 if waterlogged for prolonged period.
• Enhanced Efficiency Fertilizers (EEFs) have potential for
reducing N2O emissions but highly variable and site
specific.
• Farming system history plays a highly significant roles in
the magnitude of N2O emissions.
37. Top 10 findings to date
• Magnitude of N2O emissions is heavily dependent on
the ability to produce and retain significantly large
amounts of biomass and readily decomposable
carbon.
• Tendency for increased inputs of carbon in irrigated
and medium-high rainfall cropping systems of NE
Aust. (i.e. retaining residues and use of legume N
sources) will potentially increase N2O emissions.

44. Conclusions
• Increased emphasis on carbon farming and a wide
variety of carbon enhancing strategies (proven and
unproven) will potentially have a major impact on N2O
emissions.
• Maintaining profitability requires an emphasis on
reducing emissions intensity (GHGs/unit product) not
just GHGs in isolation.
• The significant variability in the impact of management
practices, rotations, EEFs and nitrogen inputs across a
wide range of climates and soils underscores the need
for increased use of a variety of simulation modelling
techniques to predict the behaviour of mitigation
practices in different situations.
