This is a study on how the widespread use of GlobalGAP standards, a food safety certification scheme commonly used by the large food retailers, affects African countries’ propensity to export fruit and vegetables. The theoretical framework for this study is based on the ongoing debate on whether standards work as a catalyst or a non-tariff barrier to trade. The question at issue for this paper foc
Germany’s current energy grid was built to match energy production from major power plants (coal, gas, nuclear). Due to the 2011 decision to exit all nuclear power until 2022 and ambitious national CO 2 reduction targets, the need to modernise and extend the grid has received substantial attention. In the past, implementation of grid extension projects had shown to be slow and raise serious pu
This paper is an investigation of the urban climate of Malmö (population about 230,000) in the south of Sweden. The purpose for this study has been to investigate and combine information, obtained by two different methods for measuring temperature, conventional equipment as well as thermograms taken from the air.
During the process of its socio-economic development, Vietnam has been achieving the remarkable successes in poverty reduction, and the economic growth that is recognized by the World Bank, the Asian Development Bank and the international communities. However, the fast industrialization and urbanization are attracting the increasing inflow of rural migrants to urban areas. Besides that, the govern
The idea of a common language has always existed in some form in China, from the ya yan of Confucius to the modern day mandarin – known as Putonghua. During the Qing dynasty the Beijing dialect slowly became dominant, and in the years following the Xinhai revolution this was made formal through a series of decisions aimed at standardizing the language. The current definition dates back to the 1956
Det sker en allt snabbare förändring av landskapet. Urbaniseringen ökar hela tiden med bostadsbebyggelse, industrier, flygplatser och vägar för att nämna en del av det. Andra företeelser minskar istället i antal och utbredning såsom ängs- och hagmarker, lövskog, märgelgravar, åkerholmar, stengärden, bäckar med flera. Detta är allvarligt då växt- och djurarter utrotas och fler riskerar att försvinn
Dependence on fossil fuel is an issue for the many countries, it is particularly challenging for Small Island Developing States. Reliance on fossil fuel is becoming for many SIDS an economic burden. Due to the constant fluctuation in oil prices which leads to high fuel prices, high cost of living, and high electricity bills when the price of this commodity is high. This results in constant pressur
Partially due to years of poor water management practices in Moldova, water resources are increasingly becoming a concern. This situation is intensified by the pollution of water bodies that could be used for drinking water supply. An improvement of the water supply system in Moldova’s capital city Chisinau would result in an upgrading of water quality and hence increased health and living conditi
Fjärranalys har med hjälp av bilder med hög temporär upplösning blivit ett kraftigt verktyg för att övervaka Land use/Land cover (LULC) förändringar. Sudan har under lång tid varit utsatt för intensiv Markanvändning/Markytsförändringar (LULC). Dessa LULC förändringar har resulterat i omfattande land degradering. Omvandlingen av naturskog och skog är fortfarande den vanligaste orsaken till expansioRemote sensing with high temporal resolution images has become a very strong tool for monitoring the Land use/Land cover (LULC) changes. Sudan has long been experiencing intense LULC changes. These LULC changes have resulted in widespread land degradation. The conversion of natural woodland and forest is still the main source for agricultural expansion in Sudan. Rainfed mechanized farming (RMF) is
The Gaia satellite, to be launched in August 2012, will measure highly accurate absolute parallaxes of hundreds of millions of stars. This is done by comparing parallactic displacement of stars in different parts of the sky. The accuracy of this method highly depends on the stability of the so-called basic angle between the two fields of view of the Gaia instrument, and periodic variations could l
Ett antal studier har visat att buller har negativa hälsoeffekter (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Exempel på problem som kan uppstå på grund av buller är sömnsvårigheter, hjärt- och kärlsjukdomar, minskad inlärning och reducerad kognitiv förmåga (Berglund, Lindvall & Schwela 1999). Dessa typer av hälsoproblem leder till lidande för den enskNoise has negative health effects according to a number of studies (Barregård et al. 2005; Rosvall et al. 2009; Nilsson, Eriksson & Palmqvist 2009). Example of problems that can occur from exposure to noise is sleeping disturbances, heart diseases, lessened learning and reduced cognitive performance (Berglund, Lindvall & Schwela 1999). This kind of problems cause suffering on a personal le
