"Vi klimatforskare stödjer Greta och skolungdomarna"

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- DN DEBATT 15/3. Sedan industrialiseringens början har vi använt omkring fyra femtedelar av den mängd fossilt kol som får förbrännas för att vi ska klara Parisavtalet. Vi har bara en femtedel kvar och det är bråttom att kraftigt reducera utsläppen. Det har Greta Thunberg och de strejkande ungdomarna förstått. Därför stödjer vi deras krav, skriver 270 klimatforskare.

Forskningsöversikt (refereegranskat)abstract
- Land degradation, as a threat to smallholders in the tropics, attracts less attention than other global challenges. In addition, gaps between scientific understandings of land degradation and international policy regimes are problematic. We identify the three most significant debates including their different policy implications: desertification in the Sahel, nutrient depletion in Africa, and rural reforms in China. Using a political ecology frame across disciplines, scales of inquiry, and regional experiences, we nuance the often polarized scientific debate while seeking to bridge the gap between science and policy. Three main findings emerge: State-led rural reforms in China represent an important approach to land degradation; a renewed focus on agriculture and sustainability in development discourses opens new ways for tackling nutrient depletion with combined sociotechnological reforms; and a policy void in Africa paves the way for market mechanisms, such as payment for environmental services, that are insufficiently understood and put fairness at risk.

The African Land-Grab: Creating Equitable Governance Strategies through Codes-of-Conduct and Certification Schemes
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper examines two failed land acquisition processes for food and biofuels production in Africa with the aim to establishing more equitable governance strategies. More specifically it explores the roles of certification schemes and codes-of-conduct can play in these processes. The two cases used are the South Korean Daewoo Logistics case in Madagascar and the Swedish SEKAB in Tanzania. The methods used were a literature survey and a case structuring using a multi-level (governance) framework. Analyses reveal that governance disconnects occurred between the regional and village levels with the Daewoo-Madagascar case driven largely by a lack of transparency in the negotiation process. The SEKAB-Tanzania case failed largely due to discrepancies revealed by an interest organization and the inability of traditional governance systems to manage the scale of the project. Lastly the paper presents a framework consisting of four areas where certification schemes and codes-of-conduct can be used in order to provide a governance system in order to increase access and allocation aspects.

Estimation of PAR over northern China from daily NOAA AVHRR cloud cover classifications

Tidskriftsartikel (refereegranskat)abstract
- Incoming Photosynthetic Active Radiation (PAR) is an essential variable for modelling aboveground primary production of ecosystems through the light-use efficiency approach. A method is presented where daily classifications of cloud cover (CLAVR) from the NOAA AVHRR satellite sensor is used to estimate surface incident short wave (SW) flux from which PAR can be assessed. The study area is the Inner Mongolia Autonomous Region (IMAR) of northern China. Daily time steps of calculated theoretical incoming global radiation outside the atmosphere, is adjusted according to the clear, mixed or cloudy classification in the NOAA Pathfinder data set at 8x8 km grid-cells. For the different CLAVR classifications, empirical relationships to atmospheric transparency were established against ground measurements of SW flux. Clear pixels corresponded to an average 61% penetration of the theoretical radiation at the top of the atmosphere and mixed and cloudy pixels to 47% and 40% respectively. The CLAVR time series is evaluated regarding consistency and diurnal precision against measured SW flux and hours of bright sunshine. Modelled monthly fluxes over the growing season were acceptable compared to measured (NRMSE = 6. 6%) and about as good as deriving fluxes from measurements of bright sunshine hours. The global NOAA Pathfinder archive provides an opportunity to assess PAR over the past 20 years at a considerably higher spatial resolution than with methods based on geo-stationary meteorological satellite data sets and without interpolations from scarce measurements of bright sunshine hours.
