Presentation about how regenerative agriculture sinks carbon in soil and helps reverse global warming. Plant photosynthesis uses CO2 in the atmosphere and microbes sequester carbon in soil by eating plant exudates at roots which are sugars. Protecting microbes is critical to drawing down atmospheric CO2 and sinking it in soil. Conventional agriculture kills the microbes in the soil and adds CO2 to the atmosphere. Regenerative agriculture is carbon negative.

ENV330 Module 4 AVP Transcript Title Slide Narrator: In Module 4, we will consider the impact of food production and distribution and sustainable food production. The total amount of food grown and produced for humans has increased dramatically over the past 50 years to meet the growing demands of our human population. Agricultural production, meat production and fish catch, both wild caught and aquaculture have all increased dramatically. The world’s three largest grain-producing countries are China, the United States, and India. What kinds of stresses has this placed on the natural capital and ecosystems of the world? Slide 2 Title: Impacts of Food Production Slide content: [image of a desert] Narrator: The impacts include loss of biodiversity, soil degradation, wasting and pollution of scarce water resources, increased greenhouse gas emissions, depletion of fish stocks in the oceans, and human health problems. According to a 2002 study by the United Nations, nearly 30% of the world’s cropland has been degraded to some degree by soil erosion, salt buildup, and chemical pollution, and 17% has been seriously degraded. There are serious soil erosion problems on every continent of the world, and marine biologists say that we’ve “fished out” much of the oceans. Slide 3 Title: Dust Bowl in 1930’s Slide Content: [black and white image of a dust cloud taking over a town] Narrator: Overgrazing, poor agricultural practices including salinization from irrigation can cause erosion, desertification and dust storms. Deforestation of hillsides can also impact agriculture and ecosystems. Once a hillside has been deforested for timber, fuelwood, livestock grazing, or unsustainable farming, water from precipitation rushes down the denuded slopes, erodes precious topsoil, and can increase flooding and pollution in local streams. Such deforestation can also increase landslides and mudflows. A 3,000-year-old Chinese proverb says, “To protect your rivers, protect your mountains.” Waste of water is one of the major environmental problems associated with agriculture. The most efficient (90-95%) way to get water to the roots of crops is through drip irrigation, or Low Energy Precision Application (LEPA), which you will learn about in this module. During the Dust Bowl in the US in the 1930’s, terribly unsustainable agricultural practices in the Midwest breadbasket led to such dire conditions that millions of starving people migrated away from the farmlands. Many children died from inhaling the dust. The situation got so bad that during a Senate hearing on the issue in DC, dust from a dust storm leaked into the conference room! A few inches of top soil is all that keeps civilization from starvation – we need to protect this vital natural capital.

The potential of microalgae meals in compound feeds for aquaculture

International Aquafeed

Intensive production of mainly carnivorous fish has resulted in fish feeds containing high levels of fishmeal and fish oil, with Europe requiring around 1.9 million tonnes a year. Although this use of fishmeal was initially the recycling of waste from fishing through the use of bycatch and trimmings, due to the rapid development of aquaculture this reliance on fishmeal and fish oil is environmentally unsustainable. This has resulted in other sources of fish feed being investigated. This literature review will focus on microalgae; the composition in terms of nutritional quality, the current methods of production and associated costs along with potential future uses such as feed in aquaculture.

International Aquafeed

Live feeds are often essential for larval fish. Live feeds are proven to be essential first-feed for many larval fish, essentially all those that hatch from small eggs with limited yolk reserves and often immature feeding and digestive functions. Live feeds provide larval fish with essential nutrients that are naturally ‘microencapsulated’ in bite-sized packages. They include a high proportion of easily-assimilated free amino acids and free fatty acids, as well as digestive enzymes and beneficial bacterial microfloras in the gut contents of the prey. The swimming activity of live prey also stimulates feeding responses in larval fish, a vital concern because small larvae with very limited metabolic reserves can quickly starve if they do not promptly begin feeding actively.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
