Metoderna som används för att göra den globala livsmedelsförsörjningen tryggare har bytt fokus från själva produktionen av jordbruksgrödor till att öka människors tillgänglighet till marknader. Analyser visar att det finns ett samband mellan inkomst, avlägsenhet, och hur stor andel av god jordbruksmark faktiskt används för jordbruk. För att beräkna tillgänglighet krävs fullständig, uppdaterad, ocContemporary approaches to improving food security amongst the world’s vulnerable populations have shifted from attempts to improve crop yield to improving accessibility to markets. Analyses show that there is a correlation between income, distance from cities, and the ratio of potential agricultural production to realised agricultural production. Complete, up-to-date, and reliable road network

This study investigates whether privately funded aid projects enable a more effective development compared to publicly run, with the perspectives of local street-level bureaucrats at focus. The purpose is to highlight aid workers as much of policy is being formed and put into practice at street-level rather than policy level in developing countries. New emerging actors on the aid arena also calls

Populärvetenskaplig sammanfattning: Under de senaste årtiondena har norra Ghana drabbats av missväxt i samband med torka vid ett flertal tillfällen. Jordbrukarna i området är beroende av den mängd nederbörd som faller under den enda regnperioden, mellan april och september. En avvikelse från den årliga medelnederbörden kan därför medföra en reducering eller fullständig kollaps av spannmålsproduktiNorthern Ghana experiences one dry season per year, but severe droughts may occur more infrequently. This is of concern to the local farmers of the Tamne River Basin (northeast Ghana) who depend on adequate rainfall amounts during the rainy season. Unfavourable precipitation amounts may lead to catastrophic consequences. It is therefore crucial to develop methods for predicting the distribution of

In the present study, the effects of a single rib on the local heat transfer around a bluff body are examined by using the steady state liquid crystal technique. By varying the spacing between the bluff body and the rib, the interaction between the rib and the bluff body can be controlled. The bluff body is oriented vertically towards the flow direction and spans the whole height of the channel. T

Purpose: To assess limits for significant improvement or deterioration of visual fields in diabetic patients based on short-term test–retest variability in subjects with different degrees of retinopathy. Methods: Fifty patients with diabetic retinopathy ranging from level 10 to 75 [according to the Early Treatment Diabetic Retinopathy Study (ETDRS) severity scale] were tested repeatedly with both

In this master’s thesis I have explored what characterises the setting of dolmens and passage graves in north-eastern and south-eastern Scania, southern Sweden, if there are common features, and what meaning/connection the setting can imply. By combining field visits at twenty-four sites with search results from the Swedish National Heritage Board’s database, map studies, literature studies and pr

Popular Abstract in Swedish Små kyrkor i länder som domineras av andra religioner är ofta beträngda idag. I Malaysia växer sig Islam starkt, och islamistiska rörelser med terroristiska metoder omger landet på alla sidor. Samtidigt har även Buddhism och Hinduism fått nytt liv. Genomgående märks en skärpt hållning visavi den kristna kyrkan och en tilltagande kritik av proselytism. Från Väst finns inProtestantism in Malaysia is in many cases the result of labour migration from China and India in the 19th and 20th Centuries. Under the British colonial administration, it enjoyed a certain degree of protection. Furthermore, in the 20th Century, many Western missions started work in Malaysia often in order to strengthen and expand the ministry of existing denominations. This was particularly true

Palaeoecological methods were applied to peat and sediment cores recovered from one bog (Bråtamossen) and two lakes (Avegöl and Femtingagölen) in the Småland Uplands, southern Sweden. The general aim was to reconstruct the landuse and vegetation history for the last 6000 years in this agriculturally marginal region. The main technique was pollen analysis, which was complemented by mineral magnetic

PURPOSE: By analysing collected data using theory, we aim to interpret the design, implementation and the usage of BSC in NPO’s to be able to contribute to the research. METHODOLOGY: A case study design has been made through semi-structured interviews and backed up by a quantitative survey and internal documents. THEORETICAL PERSPECTIVES: Based on the sources given from the creators of the scoreca

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to wh

Within many-body perturbation theory, we apply vertex corrections to various closed-shell atoms and to jellium, using a local approximation for the vertex consistent with starting the many-body perturbation theory from a Kohn-Sham Green's function constructed from density-functional theory in the local-density approximation. The vertex appears in two places-in the screened Coulomb interaction W an

The goal of this contribution is to stimulate a wider reflection on the role of food consumption practices throughout prehistory. We focussed on the Jōmon communities of Hokkaidō Island in Northern Japan since these mobile foragers underwent a process of economic diversification and intensification, eventually leading to higher levels of sedentism across the Pleistocene-Holocene transition. Moreov

Universities are powerful drivers to create and advance knowledge on sustainable development. Furthermore, they can be used as a controlled environment to apply innovative technologies and approaches. This process also embraces industry and government, in the triple helix innovation model, as in the University of Campinas (Unicamp), Brazil—one of the best Latin American universities (3rd)—and imme

Background and purpose — Targeted delivery of drugs is important to achieve efficient local concentrations and reduce systemic side effects. We hypothesized that locally implanted synthetic hydroxyapatite (HA) particles can act as a recruiting moiety for systemically administered drugs, leading to targeted drug accretion. Methods — Synthetic HA particles were implanted ectopically in a muscle pouc

Citizen science is changing society's contribution to research projects worldwide. Non-experts are no longer just spectators, they are active participants and supporters of scientific work. Using citizen science, that is, data collected by laypeople, the opportunities to collect large-scale data on the environment are increasing. Such community-based and citizen scientific approaches can provide u

Drought is a major natural hazard in the Bolivian Altiplano that causes large agricultural losses. However, the drought effect on agriculture varies largely on a local scale due to diverse factors such as climatological and hydrological conditions, sensitivity of crop yield to water stress, and crop phenological stage among others. To improve the knowledge of drought impact on agriculture, this st

The social consequences of agrarian change have been widely debated. The traditional view of the lower classes becoming increasingly vulnerable due to the loss of access to resources has been met with the revisionist view that this change was counteracted by an increase in the volume and regularity of employment due to investments and new farming practices.
