Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The Water Framework Directive was incorporated into Swedish legislation in 2004. Its aim is to develop sustainable management of European surface- and groundwater and with the implementation of the directive there was a need for development of monitoring programmes and tools for assessing water quality. In response to these needs the Swedish Environmental Protection Agency opened a call for research on "Biological assessment criteria in aquatic environments". As a result of this call, a consortium of 11 partners, was granted a total budget of 47 million SEK funded by the Swedish Environmental Protection Agency's Environmental Research Grant, to pursue the research programme WATERS during 5 years. WATERS has developed better indicators and methods for classification and references in Swedish lakes, streams and coastal waters. This provides a valuable basis for a new generation of biological assessment criteria to be defined by the authorities. WATERS has also developed general methods for assessing and reducing uncertainty in classification of ecological status, as well as harmonised and transparent methods for integrated assessment. In combination, these results are expected to improve and simplify future status assessments according to the Water Framework Directive. Several teams of ecologists specialised in limnic and marine waters have contributed, led by Jacob Carstensen, Aarhus university, Richard Johnson, Swedish university of agricultural sciences, Leif Pihl, University of Gothenburg and Sofia A Wikström, Stockholm university. The programme has been coordinated by Mats Lindegarth at the Swedish institute for the marine environment. We wish to express our sincere gratitude to everyone that has contributed to the success of the programme. WATERS steering group has consisted of the coordinator, team leaders and responsible contacts at the Swedish Agency for Marine and Water Management and the Swedish Environmental Protection Agency. These have been represented by Mats Svensson and Cecilia Lindblad respectively. The authors alone are responsible for the content of this report.

Bokkapitel (refereegranskat)abstract
- I detta kapitel ges först en kort inblick i hur den vilda biologiska mångfalden blev grunden för jordbruket och utvecklats som en del av människors matlandskap inom olika lokala ekosystem. I takt med att tillgång till nya energikällor har matproduktionen och matsystemen ändrats vilket bidragit till den allvarliga, lokala och globala miljösituationen vi befinner oss i. Möjligheter till och ramverk för en hållbar matproduktion och hållbara matsystem baserade på agroekologiska system skisseras.

- The vegetation of the study area in Chobe National Park is influenced by a range of factors, including inundation by the Chobe River, soil moisture and fertility, and the impacts of different-size grazers and browsers. This chapter focuses on how the structure and species composition of the present vegetation in northern Chobe National Park is related to recent herbivory by elephants, as agents shaping the vegetation, and by mesoherbivores acting as controllers or responders, along with abiotic controllers such as soil type and distance to the river. In the study, a two-way indicator species analysis classified the vegetation data into four more or less distinct plant community groups (i) Baikiaea plurijuga-Combretum apiculatum woodland, (ii) Combretum mossambicense-Friesodielsia obovata wooded shrubland, (iii) Capparis tomentosa-Flueggea virosa shrubland and (iv) Cynodon dactylon-Heliotropium ovalifolium floodplain, named after the TWINSPAN indicator or preferential species with high cover, and the relative amount of shrubs and trees.

Making Urban Slum Population Visible : Citizens and Satellites to Reinforce Slum Censuses

- In response to the “Leave No One Behind” principle (the central promise of the 2030 Agenda for Sustainable Development), reliable estimate of the total number of citizens living in slums is urgently needed but not available for some of the most vulnerable communities. Not having a reliable estimate of the number of poor urban dwellers limits evidence-based decision-making for proper resource allocation in the fight against urban inequalities. From a geographical perspective, urban population distribution maps in many low- and middle-income cities are most often derived from outdated or unreliable census data disaggregated by coarse administrative units. Moreover, slum populations are presented as aggregated within bigger administrative areas, leading to a large diffuse in the estimates. Existing global and open population databases provide homogeneously disaggregated information (i.e. in a spatial grid), but they mostly rely on census data to generate their estimates, so they do not provide additional information on the slum population. While a few studies have focused on bottom-up geospatial models for slum population mapping using survey data, geospatial covariates, and earth observation imagery, there is still a significant gap in methodological approaches for producing precise estimates within slums. To address this issue, we designed a pilot experiment to explore new avenues. We conducted this study in the slums of Nairobi, where we collected in situ data together with slum dwellers using a novel data collection protocol. Our results show that the combination of satellite imagery with in situ data collected by citizen science paves the way for generalisable, gridded estimates of slum populations. Furthermore, we find that the urban physiognomy of slums and population distribution patterns are related, which allows for highlighting the diversity of such patterns using earth observation within and between slums of the same city.
