This document discusses mapping land degradation and sustainable land management (SLM) interventions to support combating desertification. It describes assessing where and when to intervene based on the level of degradation and mapping specific technologies and approaches. The mapping involves assessing land use systems, degradation types and extent, conservation approaches, and their impacts. This provides spatial overviews to identify priority areas and guide the scaling up of effective SLM. Lessons include developing participatory and harmonized databases to inform policy, planning, and monitoring of projects combating land degradation.

In the Davao Region of Southern Mindanao, Philippines, Integrated Water Resource Management (IWRM) has been a key framework for promoting sustainable land use in local ecosystems. However deteriorating trends continue across the watersheds and there is an absence of critical reviews to validate whether the current set of policies are providing a supportive environment for sustainable socio-ecological production landscapes .

Flood risk in urban centers across the Philippines is increasing due to changes in ecological and hydrological processes. Both global and local drivers are intensifying these changes. Climate change is triggering an increase in hydro-meteorological hazards. Local land cover degradation, urbanization, conversion of floodplains and inappropriate hydro infrastructures have all increased our vulnerability to hydrological hazards.
In order to design appropriate responses the role and function of riparian ecosystems in regulation of flood is required to be understood not only in both spatial and temporal contexts, but also in socio cultural and economic contexts. This paper will look at emerging evidence based approaches from landscape ecology and ecohydrology to develop community driven low cost interventions that can better understand and measure land use degradation and direct land use management actions that can aid sustainable flood risk reduction.
Not so wild on the wild coast: conservation of pondolandDerek Berliner
Not so wild on the Wild Coast: Landscape changes and threats to biodiversity on the Eastern Cape’s Wild Coast and the role of protected areas in communal areas

The Pondoland centre of endemism is the smallest and perhaps the most vulnerable in South Africa. Its importance has been globally recognized by its inclusion within Conservation Internationals Maputu-Pondoland- Albany hotspot.
The Wild Coast Project, a GEF funded initiative, administered by the ECPBT aims to establish a representative network of co managed protected areas across the Pondoland center and within the Wild Coast. A number of case studies are used to examine the key threats, systemic relationships between these, and the drivers of landscape change on the Wild Coast. In light of this, the question is asked: how effective the proposed community protected areas will be to ensure persistence of biodiversity on the Wild Coast?
The case studies include a number of ecosystems, including mangrove estuaries, scarp forests, and the grasslands /thorn veld/forest mosaic. Case studies are the result of numerous site visits, literature reviews, discussion with locals, and GIS analysis of past areal and satellite imagery.
The case studies reveal the essential paradox of conservation in communal areas, like the Wild Coast. On the one hand, the human footprint and level of transformation appears to be relatively low when compared to the highly transformed landscapes of commercial agriculture; but on the other hand, closer inspection and analysis of landscape and associated environment changes, reveals highly dynamic and vulnerable systems showing the signs of an ‘environmental meltdown’. This threatens not only the livelihoods of many depended on natural resources, but also the irreplaceable biodiversity associated with these areas.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

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.

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.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

• Resulting data and maps can now be used to formulate the
project intervention strategy, to identify best practices for
SLM in the region for scaling up and to guide effective and
responsive interventions at various scales
• Data will inform policy making, planning and budgetary
allocations by the concerned technical sectors at district and
transboundary levels and serve as a baseline for more integrated
landscape management approaches
• A potential outcome is the use of the method for monitoring
project impacts
• The process can also be used for justifying and developing
proposals for catchment's level interventions by concerned
communities and districts and for developing more substantive
