- This chapter explores through an understanding of the history and development of the situation of statelessness across the region – a consequence of nation-state formation, state succession and/or discriminatory ethnic, religious and gender law and policy – the striking commonalities in both the causes and consequences of statelessness. It focuses on how the Middle East and North Africa (MENA) region lacks a common language on statelessness which may have contributed to the fact that these groups are often discussed in isolation of one another, with a limited sense of having a shared cause. The chapter also focuses on how the current framework for understating statelessness in the region can obstruct opportunities to address the issue regionally and can even be used to perpetuate statelessness. Discrimination against women in nationality laws can be found in legislation around the world. Statelessness has also resulted from the 'Arabisation' movement that took hold of the region in the 1960s and 1970s.

- We present a method to study the morphology of living, dividing and dying cells using DHM. DHM is a non-invasive, non-destructive and non-phototoxic method which allows the user to perform both qualitative and quantitative measurements of living cells over time. We show here our results on cell division and cell death in single cells. The morphological analyses performed here show changes caused by cell death and cell division, and indicate the possibilities to discriminate between different types of cell death. Cells dying in an apoptosis-like manner display different cell area and cell thickness profiles over time compared to cells dying in a necrosis-like manner, although their volume profiles are very similar. Dividing cells show a characteristic dip in the volume profile, which makes them easily distinguishable. Also, several previous studies show the versatile abilities of DHM. Different cell types have been studied and the morphology has been used to determine cell functionality as well as changes in morphology related to the environment. Cell morphology parameters can be very useful when following the effects of different treatments, the process of differentiation as well as cell growth and cell death. Cell morphology studied by DHM can be useful in toxicology, stem cell and cancer research.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Digital holography is a novel technique that has been developed recently to study living cells. The technique is an innovative, non-destructive method with possibilities to study living cells over time. We are investigating cell number, growth, viability and death of adherent cells using digital holography, which is a novel, label-free, imaging technique for biological applications. We have recently demonstrated that digital holography is highly comparable to the conventional manual cell counting method using a hemocytometer (Mölder et al., 2008). Digital holography is a method that gives us information about the refractive index of cells, which can change under different circumstances. The technique is cheap, fast and simple to use. The unique measurable parameters are the cell number, cell area, thickness and volume, which can be transformed to proliferation, migration, viability and cell death. The digital holographic images produced can provide both quantitative and qualitative phase information from a single hologram. Future applications can include real-time cell monitoring of various parameters of cells of different diseases in response to clinically relevant compounds.

- Digital holographic (DH) microscopy is a digital high-resolution holographic imaging technique with the capacity of quantification of cellular conditions without any staining or labeling of cells. The unique measurable parameters are the cell number, cell area, thickness, and volume, which can be coupled to proliferation, migration, cell cycle analysis, viability, and cell death. The technique is cell friendly, fast and simple to use and has unique imaging capabilities for time-lapse investigations on both the single cell and the cell-population levels. The interest for analyzing specifically cell volume changes with DH microscopy, resulting from cytotoxic treatments, drug response, or apoptosis events has recently increased in popularity. We and others have used DH microscopy showing that the technique has the sensitivity to distinguish between different cells and treatments. Recently, DH microscopy has been used for cellular diagnosis in the clinic, providing support for using the concept of DH, e.g., screening of malaria infection of red blood cells (RBC), cervix cancer screening, and sperm quality. Because of its quick and label-free sample handling, DH microscopy will be an important tool in the future for personalized medicine investigations, determining the optimal therapeutic concentration for both different cancer types and individual treatments.

Agricultural Land Degradation in Portugal and Greece

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Agricultural land degradation is a global problem affecting food production and other ecosystem services worldwide such as water regulation. It is driven by unsustainable land use and management practices (e.g. intensive tillage, overuse of agrochemicals) and can be aggravated by future climate change. Land degradation is particularly problematic in arid and semi-arid areas of southern Europe, and distinct soil degradation processes impair agricultural areas in Portugal and Greece. This chapter aims to improve understanding of various degradation processes affecting agricultural land, including soil erosion, compaction, contamination, and salinity and sodicity. It summarises the scientific literature on the current status of these degradation processes in agricultural areas of Portugal and Greece and their main causes and consequences. Moreover, it provides examples of best management practices implemented to mitigate agricultural land degradation. Some degradation processes are relatively well documented (e.g. erosion), while knowledge of the spatial extent of others such as soil compaction is still limited. A better understanding of soil degradation processes and of the counter-impacts of improved agricultural management practices is critical to support decision-making and ensure long-term fertility and productivity, thereby maintaining the sustainability of agriculture.

- Mitigating and adapting to increasing flood risk driven by climate change and growing urbanization is still a challenge for humanity. Over the last decades, the Nature Based Solutions (NBS) approach has received increasing interest from governments, academia and society, but its implementation is still in its infancy. This volume presented an up-to-date compilation about the current knowledge on NBS regarding their potential to mitigate several types of floods recorded in different environments, the associated advantages and limitations, and the barriers affecting their wider implementation. This concluding chapter provides a synthesis of the main messages of the chapters included in this volume, and it highlights the relevant aspects that must be considered for an effective and broader application of NBS. In this regard, particular attention is given to the need to maximize their multifunctionality and to consider the transdisciplinary nature of the NBS approach.
