Prof. Johan Rockström presented on establishing a new paradigm for sustainable intensification of agricultural development. He argued that humanity has reached a planetary saturation point and a great transformation is necessary to achieve global sustainability. This requires integrating agriculture and ecosystems management, adopting a nexus approach considering land, water, energy links, and reforming institutions for integrated resource management within planetary boundaries. Sustainable intensification through upgrading rainfed and irrigated agriculture, water management, and landscape restoration can meet food needs while maintaining ecological resilience.

This slideshow presents a series of graphics, photographs and statements reflective of integrated water resource management with specific reference to forest management in a changing climate. We are already experiencing the migration of animals and humans with climate shifts. The severity and frequency of wildfires, droughts, floods and ocean acidification are also increasing. Impacts to our economy, infrastructure and atmosphere have lead us to difficult choices regarding land use and future policy development to better manage our natural resources.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne

All these questions and more will be explored as we talk about matching clients’ needs with what your agency offers without pulling teeth or pulling your hair out. Practical tips, and strategies for successful relationship building that leads to closing the deal.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Editor's Notes
Ag trade-offs interesting as it’s a service of high importance for society… Interface of private and common propoerty
Vi är alla beroende av fertila jordar. Dock förs näring ut från jordar via vind/vatten-erosion, foder/bete till djur och mat till människor på både landsbygd och städer. För att kompensera för förlusterna och hålla uppe skördarna så använder vi oss i det morderna jordbruket av kemiska gödselmedel. Jordbrukssektorn arbetar med att minska förlusterna från erosion och djurskötsel. Den näring som försvinner med skörden betraktas dock ofta som ”förlorad” från jordbrukssektorns synvinkel. Sanitetssektorn satsar krut på att hindra smittspridning och tänker inte kretslopp. Humangödsel blind fläck i systemet, ett viktigt hållbarhetsgap mellan jordbruks och sanitetssektorn. I utvecklade länder vi äter mycket kött (näringsförlusterna i djurhållningen mkt större), använder mkt konstgödsel, relativt sett kretslopp av humangödsel mindre viktigt på kort sikt för jordbruket, men viktigt för miljöskydd och på lång sikt I utvecklingsländer kan återanvändning det göra stor skillnad – I Afrika, storleksmässigt ca samma mängd näring via djur som människor och som används som konstgödsel på kontinenten.
