The document proposes a mallee system for growing and harvesting energy trees in Australia's wheatbelt region. The system would involve belts of coppicing, drought-tolerant trees integrated with grain and livestock farms. Trees could be regularly harvested every 3-5 years. Harvested biomass would be transported up to 50 km to processing centers where it would be converted into renewable energy sources like char and oil. The goal is to establish a viable industry by 2025 that generates 176MW of energy and offsets 9.1 million tons of CO2 emissions annually. Challenges include harvest and transport costs, as well as ensuring long-term sustainability and carbon balance. Benefits include environmental improvements, economic opportunities for farmers, and energy
AR5 AFOLU mitigation challenges and prospects for Africaipcc-media
This document summarizes a presentation on agriculture, forestry and other land use (AFOLU) mitigation challenges and prospects for Africa. It notes that AFOLU accounts for approximately 25% of global greenhouse gas emissions and discusses challenges including financing, poverty, institutional barriers, and competition for land. It also outlines options for managing trade-offs between mitigation and adaptation efforts in the AFOLU sector.
The document discusses sustainable agricultural development in Brazil, focusing on opportunities to mitigate greenhouse gas emissions through practices like restoring degraded lands, expanding integrated crop-livestock systems, biological nitrogen fixation, no-till planting, and intensifying pastoral systems. It outlines Brazil's targets for adopting these practices on millions of hectares and estimates the resulting reductions in carbon emissions. It also describes research at Embrapa on developing sustainable technologies and systems to support adaptation, food security, and low-carbon agriculture in Brazil.
The GLOBIOM model is a global partial equilibrium model that can be used to study land use and its impacts. It has 30 geographical regions modeled at varying spatial resolutions. It optimizes land allocation between major agricultural crops, livestock, forestry, and bioenergy to maximize economic surplus. Model outputs include production, trade, land use, and greenhouse gas emissions. The model was applied in a case study of the Congo Basin that examined scenarios of infrastructure development, productivity increases, and REDD policies on deforestation and its impacts.
This document summarizes a study examining the effects of future climate change and higher crop yields on farm management and income in Finland. Crop modeling was used to simulate future spring and winter wheat yields under different climate scenarios, showing potential yield increases of 15-30% by 2040-2070. An economic model then analyzed how higher yields may impact land use, input use, farm income, and greenhouse gas emissions at the farm level under varying price scenarios. The results suggest that higher yields could lead to 50-60% greater production, 36-46% higher incomes, and 27-33% lower emissions per kilogram produced, allowing for sustainable intensification of agriculture.
The document summarizes a case study on agroforestry carbon finance schemes in Central Sulawesi, Indonesia. It analyzes four different household classes involved in cocoa agroforestry systems with varying levels of shade tree cover and management intensity. Linear programming models were used to evaluate the impact of carbon payments on household income under different scenarios. The results show carbon payments targeting shade-intensive systems could increase incomes of poorer households, stop deforestation, and promote environmentally sustainable land use, creating a "win-win-win" situation.
This study assessed the environmental impacts of using winter cereal rye cover crops as a climate change adaptation strategy in corn-soybean rotations across four experimental sites. Models were used to predict greenhouse gas emissions, soil erosion, and nitrate leaching under current and future climate scenarios with and without cover crops. Results showed that cover crops reduced nitrous oxide emissions, soil loss, and nitrate loss without affecting corn yields. However, cover crops required additional energy inputs for establishment and termination. The effectiveness of cover crops varied by location depending on climate and soil conditions. Overall, cover crops were found to mitigate many negative environmental impacts of climate change in corn systems.

Session 6.2 ecosystem services trade offs and synergies of rubber agroforestryWorld Agroforestry (ICRAF)
This document summarizes research on land use change and ecosystem services trade-offs under uncertainty in rubber agroforestry systems in Indonesia. An agent-based land use model was developed to simulate different scenarios, including business as usual, subsidies, and payments for ecosystem services schemes. The model found that PES reduced carbon emissions and biodiversity loss compared to other scenarios. Uncertainty in crop yields and prices was also modeled over 30 years. PES was found to substantially increase farm profits and reduce income variability under different policy options and payment levels. While PES for agroforestry alone increased agroforest area and conservation, PES for all perennial land uses increased employment but reduced agroforest extent.
China: Adapting Grain Production to Climate ChangeICARDA
This document summarizes grain production characteristics and challenges related to climate change in China. It notes that China has diverse topography including mountains, plateaus, basins and plains. Historically, the majority of agricultural land was used for grain but that percentage has decreased in recent decades. North China faces increasing water scarcity and competition over water resources between different sectors. Drought has negatively impacted agricultural areas and production over the past decades. The document presents statistical analysis showing that grain yields are positively correlated with higher irrigation and stable harvesting ratios. Improving irrigation infrastructure and increasing stable harvesting areas can significantly increase yields, especially for regions with currently lower yields.
University of Aberdeen and the International Maize and Wheat Improvement Center (CIMMYT) have been collaborating to use the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) Mitigation Options Tool (CCAFS-MOT) to estimate greenhouse gas emissions from Indian farming and identifies cost-effective mitigation options. Sylvia Vetter has presented a poster with preliminary results of this project at EGU – European Geosciences Union General Assembly in Vienna in April 2016.

It provides information on the International Renewable Energy Agency (IRENA) including its mission, members, and location. The document also discusses renewable energy targets for Ukraine by 2030, noting biomass could provide 0.8 exajoules of energy while Ukraine has a biomass potential of 1.1-1.8 exajoules, leaving potential for export. Sustainable sources of biomass are identified as agriculture residues, forestry residues, and energy crops.
This document discusses New Zealand's reporting obligations under the Kyoto Protocol for land use, land-use change, and forestry (LULUCF). It outlines how New Zealand will calculate and report carbon stock changes and greenhouse gas fluxes from 1990 to 2012 using land use mapping, permanent forest plots, LiDAR scanning, and satellite imagery. Methods are being developed to estimate carbon stocks in forests, croplands, and grasslands to meet UNFCCC reporting requirements.
This document outlines a collaborative project between CGIAR-ESSP to study the pressures on agriculture from climate change mitigation efforts. The project will integrate global assessment models, global agricultural models, and farm household models to understand the impacts of ambitious climate goals on food security and livelihoods. It will examine land use change scenarios and policy options through both top-down global modeling and bottom-up analysis of regional case studies. The goal is to better assess the challenges, risks and opportunities climate mitigation presents to the agriculture sector and food security worldwide.
Defining, Measuring, and Incentivizing Sustainable Land Use Kim Nicholas
This document discusses defining, measuring, and incentivizing sustainable land use to meet human needs. It examines land use change scenarios in Sweden and their impacts on ecosystem services. The scenarios include a current land use scenario, a scenario that doubles cereal production, and an intensified production scenario. Modeling results show that increasing or intensifying crop production decreases nitrogen retention by around 40% compared to current land use. The document advocates finding an optimal tradeoff between conflicting ecosystem services like food production and biodiversity loss.

Sustainable Development of Bioenergy from Agriculture Residues and EnvironmentTriple A Research Journal
This communication discusses a comprehensive review of biomass energy
sources, environment and sustainable development. This includes all the
biomass energy technologies, energy efficiency systems, energy
conservation scenarios, energy savings and other mitigation measures
necessary to reduce emissions globally. The current literature is reviewed
regarding the ecological, social, cultural and economic impacts of biomass
technology. This study gives an overview of present and future use of
biomass as an industrial feedstock for production of fuels, chemicals and
other materials. However, to be truly competitive in an open market
situation, higher value products are required. Results suggest that
biomass technology must be encouraged, promoted, invested,
implemented, and demonstrated, but especially in remote rural areas.
Keywords: Biomass resources, wastes, woodfuel, biofuels, energy,
environment, sustainability related with bioenergy development, disperse
systems formulation science, surfactant sciences
Biomass resource assessments quantify existing or potential biomass materials in a given area. They help reveal biomass status, enable conservation measures, and ensure sustained biomass supplies. A biomass resource assessment identifies surplus biomass availability for power generation. It analyzes conversion technologies and performs techno-economic analyses of bioenergy options. Assessments estimate biomass from agriculture, forestry, livestock, and other sources. They also estimate biomass consumption. Surplus biomass availability is determined by comparing supply and demand.
Sesti project: Global Sustainable Energy optionsVictor Van Rij
This presentation gives the result of the emerging issues analysis of the SESTI project on the energy domain in 2010. It provides the questions around 5 of the less well known future sustainable options/risks that were discussed in the project. The topics that were addressed are still worth while to review today.
These topics were :
1. Enhancement of the photosynthetic cycle on global scale to provide all food, energy and maintain biodiversity (briefly biomimics)
2. Use of desert areas for gaining solar energy (the DESERTEC scheme)
3. Hybrid nuclear fission-fusion to speed up nuclear fusion
4. The unknown risks of going deeper and further for energy mining
5. The unknown risks of and hydrogen leaking economy
Increasing the storage of carbon in the soil has been a controversial strategy for addressing climate change mitigation. What is the potential and why is there debate about this? How can we push beyond the debate to constructive action?

This document discusses the potential for expanding wood-based energy sustainably. It notes that modern biomass could more than triple by 2030, providing over 90 exajoules of energy. However, challenges include issues related to food security, land use change, and low oil prices. These can be addressed through sustainable intensification of agriculture and forestry to boost yields without expanding land use, making use of residues, and improving efficiency. There are large potential sources of biomass from closing yield gaps, better use of pastureland, and reducing food losses, totaling over 2 billion hectares that could provide around 300 exajoules. Policies to support planted forests and short-rotation tree crops on appropriate lands could boost
Bioenergy and Land use change: Local to Global ChallengesJeanette Whitaker
This document summarizes research on bioenergy and land use challenges from local to global scales. It discusses the types and uses of bioenergy globally as well as potential environmental risks like land use change emissions. The research assessed carbon savings from bioenergy production, finding soil carbon stock changes and N2O emissions significantly impact greenhouse gas balances. An ecosystem land use modeling tool was developed to explore land use change scenarios. The document emphasizes remaining uncertainties around soil carbon changes and recommends research priorities to increase understanding and design policies that mitigate risks of bioenergy expansion.
The document discusses the energy and environmental challenges in Africa. It notes that Africa has low electricity access and insufficient generation capacity, with high connection fees and unreliable power supply. Many rely on traditional biomass like wood and charcoal for cooking and heating. This causes problems like deforestation and indoor pollution. Solutions proposed include investing in reliable and affordable electricity sources that are also environmentally friendly, like natural gas or geothermal. Improving access to cleaner cooking options could also help reduce biomass usage and its associated impacts.
This presentation shows how soil carbon can help combat climate change. The presentation was held by Louis Verchot (Director, Soils Research Area, CIAT/WLE) at the Soils Advantage event, part of the Agriculture Advantage 2.0 series at COP24.
Rangeland Carbon Sequestration In Californiaandrewfynn
There are several methodological elements that could be combined to create a balanced rangeland carbon sequestration protocol, including direct soil sampling, spectroscopy methods, eddy covariance towers, remote sensing, and ecosystem models. A successful protocol may have a simple front-end using visual indicators and some direct sampling, combined with a sophisticated back-office using modeling, analysis, and new technologies to drive adoption rates. Both soil carbon and tree carbon should be considered given their interactions and impacts on ecosystem functions.

- Current climate scenarios envision a 70-150% increase in EU biomass use for energy and materials by 2050 compared to present levels, totaling 17-25 EJ.
- However, available sustainable biomass supply for the EU is estimated to be only 11-13 EJ, leaving a gap of 40-100% between demand and supply projections.
- Relying on projections for biomass use that exceed likely sustainable supply risks major trade-offs with key environmental objectives like biodiversity and climate change. A course correction is needed to prioritize biomass uses.

It also describes the steps involved in developing a land-based carbon accounting system for a smallholder agriculture project in Western Kenya using the Sustainable Agricultural Land Management methodology. This includes establishing a monitoring system to measure changes in soil organic carbon and crop production over time to quantify carbon credits. The document compares the costs of using direct soil measurements versus an approach based on crop production and activity monitoring using a soil simulation model.
This document summarizes a study on the viability of growing shrub willow as a bioenergy buffer crop on agricultural fields in the US Midwest to improve sustainability. Key findings include that shrub willow buffers substantially improved nitrogen use efficiency, produced comparable biomass yields to unfertilized monocultures, improved water quality by reducing soil and nitrogen losses, and provided other ecosystem services. However, shrub willow did not provide positive net revenue due to high land rental costs. It could be more economically competitive than corn in marginal soils or when considering the monetary value of ecosystem services provided. While not financially viable on its own currently, integrating shrub willow buffers shows potential to improve the environmental sustainability of agroecos

Applying science fiction to approach the futureIEA-ETSAP
The document discusses using science fiction to think about future energy systems. It proposes applying system analysis models to explore different technology combinations that meet future energy needs. However, it notes that these models do not consider social factors like behavior and justice. It suggests using genres like climate fiction and solar punk to bring more collective narratives about energy futures. Specifically, it advocates using a hackathon approach to gather knowledge and create imaginary fiction stories around different future scenarios to help build worlds and consider the human aspects of energy system design.
Will it leak?: Discussions of leakage risk from subsurface storage of carbon ...IEA-ETSAP
The document discusses carbon capture and storage (CCS) and the potential risks of leakage from subsurface storage of carbon dioxide. It provides background on CCS, explaining that carbon dioxide is captured from industrial sources and injected underground for permanent storage. It then discusses four main types of potential subsurface leakage: 1) capillary leakage if seal rocks have larger particles, 2) exceeding the fracture gradient of the seal, 3) leakage along or across faults, and 4) leakage from new or legacy boreholes. The document analyzes case studies of both CCS and carbon capture, utilization, and storage (CCUS) projects to illustrate examples of each leakage type. It concludes that CCS/CCUS has a low overall risk but is not
Long-Term Decarbonization Pathways In Emerging Economies: Insights From 12 Mo...IEA-ETSAP
This document summarizes the preliminary results of a study comparing long-term decarbonization pathways in 12 developing countries and 2 regions modeled using the Electricity Planning Model. Key findings include:
1) Ambitious decarbonization would require annual investments of 1-3% of GDP, compared to around 1% for business-as-usual scenarios.
2) Renewables, led by solar, would dominate capacity additions. Conventional plants would operate more flexibly to integrate variable renewables.
3) Achieving deep decarbonization would significantly increase energy costs but carbon prices of $20-120/t could enable cost-effective emissions reductions.
There is a tremendous amount of news being disseminated every day online about dangerous forever chemicals called PFAS. In this interview with a global PFAS testing expert, Geraint Williams of ALS, he and York Analytical President Michael Beckerich discuss the hot-button issues for the environmental engineering and consulting industry -- the wider range of PFAS contamination sites, new PFAS that are unregulated, and the compliance challenges ahead.
Widespread PFAS contamination requires stringent sampling and laboratory analyses by certified laboratories only -- whether it is for PFAS in soil, groundwater, wastewater or drinking water.

(Q)SAR Assessment Framework: Guidance for Assessing (Q)SAR Models and Predict...hannahthabet
The webinar provided an overview of the new OECD (Q)SAR Assessment Framework for evaluating the scientific validity of (Q)SAR models, predictions, and results from multiple predictions. The QAF provides assessment elements for existing principles for evaluating models, as well as new principles for evaluating predictions and results. In addition to the principles, assessment elements, and guidance for evaluating each element, the QAF includes a checklist for reporting assessments.
This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.

2. Bioenergy: linking energy markets and agriculture
“Massive production of energy, mainly liquid fuels, from agricultural resources will
link agricultural and energy markets tightly. The new market integration is perhaps
the most fundamentally important change to occur in agriculture in decades. The
link between energy and agricultural markets requires an integrated environment
to study these markets and design policy alternatives to guide them toward
designated goals.”

• Currently, TIAM lacks adequate representation of both land use and agriculture
• This undermines the credibility of resulting high bioenergy scenarios
3. TIAM: linking bioenergy, agriculture and land use
• Ideally, gridded, spatially explicit land use and crop models should be used
• This is resource-intensive (funds, person-hours, computing power)
• Mostly done via soft-link approach:
• Models exchange key variables in iterated runs
• This method may result in sub-optimal solutions
• LU and agriculture can also be represented as commodity flows and processes
• Introduce a methodology to include it in TIAM

• Local conditions (grid cell level)
• Management systems (challenging to model)
• Dominated by short-term decisions (agriculture)
• Carbon stocks in natural land uncertain (LU transitions)
