Large environmental, health, social and economical problems are connected with the use of fossil fuels and, in a dominating part of the world, also the use of firewood. The goal for this project was to develop and design an optimal solar oven system intended for food cooking and water pasteurisation. Further the advantages and disadvantages, compared with other energy resources were evaluated. Tests were carried out in Sweden as well as in Sri Lanka. An extensive range of prototypes were tested and sifted out to a small number of designs that were tested in Sri Lanka. A large number of evaluations and tests were carried out on many different materials, among others tests were conducted according to the international standard “Testing and Reporting Solar Cooker Performance ASAE S580 JAN03”. The report shows a number of benefits compared to previous reports on the subject, for example the development of indoor tests, the extensiveness and objectiveness of the tests, and the fact that the report combines extensive practical test results with solid theoretical background information. The test resulted in two solar ovens with the same parabolic design but made out of different materials. One oven is cheaper, simpler to produce and is considered for the target group poor people in developing countries. This is made out of a corrugated cardboard that is covered with aluminium foil. The second oven is more expensive but also more durable and is intended for more wealthy people in the west that wants a good alternative to regular ways of cooking food. It is made out of aluminium plate and mirrors.

In 1948, the title Ceylon: Island Without Problems was thought to be a suitable one for a proposed documentary film of the Island. At present the title would be a misnomer as the whole country is divided by communalism. The problem of communal disunity needs urgent consideration. [...]

This thesis investigates small-scale community-based shrimp aquaculture (CBSA) in northwestern Sri Lanka. The objectives are to explore: (1) community-based shrimp aquaculture; (2) commons institutions and application of commons rules; and (3) policy implications (i.e., as an alternative to large-scale operations in ensuring sustainability). Data were gathered from three communities in northwestern Sri Lanka, through participant observations; semi-structured interviews; focus group discussions; and key informant interviews. Presence of small-scale community-based institutions is evident. Arguably, commons in this context are social-ecological systems, including the interconnected natural water body. Main characteristics of the existing resource governance system are multi-level commons institutional structure; zonal crop calendar system; collaborative/participatory management approach; and better management practices. A SWOT (strengths, weaknesses, opportunities, threats) analysis proves the viability of existing CBSA. This thesis recognizes CBSA as an alternative approach to large-scale aquaculture operations to ensure sustainability in the long run.

En typiskt singalesisk måltid tar lång tid att göra, den ska bestå av flera smårätter och gärna med kryddor från hemlandet. Har den kulturella måltidssynen hos de singalesiska kvinnorna förändrats, förstärkts eller påverkats av att vara i ett annat land och i så fall varför? Är det fortfarande den singalesiska husmanskosten som anses vara ett ”proper meal”? Syftet är att undersöka fem singalesiska kvinnors egna uppfattningar om ämnet ”proper meal” från ett singalesiskt perspektiv och undersöka om deras uppfattning har förändrats under tiden de bott i Sverige. Studien är kvalitativ och för att undersöka hur singalesiska kvinnor uppfattade och tänkte kring dessa frågor har en pilotfokusgrupp samt en skarp fokusgrupp skulle utgjort metoden för datainsamling.  En lunch eller middag ska enligt denna studie vara singalesisk och därigenom bestå av en kött- eller fiskrätt, serveras med ris och två till tre grönsaker som tillbehör för att den ska vara en riktig måltid både till vardagar och helger. Kopplingen till ”proper meals” kan göras från ett singalesiskt perspektiv för vardags-, helg- och även festmåltider. Det framstod också hur matlagningen var förknippad med identiteten och den kulturella tillhörigheten.

Abstract This research is concerned with exploring, describing and interpreting the potential of community participation in improving food security in rural households in the Kolonna area. It explores the importance and value of the ancient village tank system as a vehicle for enhancing both community participation and food security. In Sri Lanka there still exists a network of large and small irrigation tanks and associated distribution and drainage channels that was originally established 1000-2000 years ago. This system apparently formed the basis of an effective cooperative social system that endured for centuries. More recently, several centuries of colonial rule caused the abolition of this participatory system by the British and the social structure and tank system of the village collapsed. Since independence in 1948, several government departments and international institutions have been trying to rebuild this social structure around the village tank, but with only limited success. This thesis describes efforts to document the potential for incorporating historical knowledge and farmers’ perceptions into sustainable community participatory programs in agricultural activities based on village tanks, with the aim of improving food security in a rural area of Sri Lanka. A mixed methods approach was employed to address the research questions identified for the study. It involved predominantly qualitative methodology including focus groups and individual interviews with a range of stakeholders including government and spiritual authorities allowed the exploration of the realities of village life and issues affecting food security. Significant findings not evident in typical governmental statistical reports include the following: (1) Household food security in rural areas is still a major problem. Agricultural production rather than purchased food is the main source for caloric intake of rural households and many farmers experience food insecurity due to unexpected seasonal crop failures. Furthermore, almost 10% of the residents of Kolonna area experience acute food insecurity, which occurs due to poverty. These people typically do not have secure access to land for growing their own crops but rely on casual wages work. (2) The major constraint to food security identified by respondents was lack of consistently available and equitably distributed irrigation water, although in contrast occasional flood damages to land and crops s due to flood was also a significant problem. Some farmers also believed that marketing and distribution channel constraints limited their commercial returns and income, and capacity to enjoy year-round food security. v (3) Despite the existence of several community participatory programs in the Kolonna area, they are not perceived to be successful. Only one third of the villagers are involved in these programs and more than 40% were unaware of their existence. Major criticisms included the perception of political interference and favoritism in the process governing their operations, which favored relatively few recipients. . (4) There appears to be strong support amongst villagers for revision of cooperative approaches such that management is by representatively elected independent committee that allow involvement of the most suitable farmers. This perception was linked to beliefs that a renewed focus on the village tank would be ultimately more beneficial than focusing solely on improving food security, because of the capacity to incorporate traditional community participatory approaches. Valuable features of the traditional system include sharing rather than hiring labor, dividing communal tasks among community members, and rules and regulations imposed by a recognized and accepted governing body. The implications of these findings for further research, policy and practice are discussed.

[Abstract]: During the last 27 years, the banking industry in Sri Lanka has undergone a series of changes through financial reforms, advancement of communication and information technologies, globalisation of financial services, and economic development. Those changes should have had a considerable effect on efficiency, productivity change, market structure and performance in the banking industry. The motivation of this study is to investigate empirically the impact of those changes on the banking industry. Thus, this study aims to address three main research issues related to the banking industry in Sri Lanka, namely:1. Whether deregulation of the financial services sector has led to improvement in efficiency and productivity gains.2. Whether banks’ inefficiency in the banking industry in Sri Lanka is determined by a set of microeconomic and macroeconomic variables.3. Whether the changes in efficiency or changes in market structure have influenced the overall operational performance of banks in Sri Lanka.This study adopts a non-parametric Data Envelopment Analysis (DEA) and Malmquist Productivity Index (MPI) to measure efficiency and productivity gains of banks in Sri Lanka using financial and other information representing all local banks over a sixteen year period from 1989 to 2004. Input and output variables are refined to represent the intermediation and assets transformation roles of banks. Window analysis of mean estimated efficiency scores in both aspects indicates a negative trend in estimated efficiency during the study period. However, the analysis of efficiency scores (intermediation) of different forms of banks shows a negative trend during the first half of the study period and a slight positive trend during the end of the second half. These results imply that deregulation may have failed to improve the efficiency of the Sri Lankan banking industry in the short-term. However, the expected benefits of deregulation can be achieved in the long-term. Interestingly, the two state-owned banks have responded poorly to the initial phase of Sri Lankan financial reforms. However, the improved autonomy given to boards of management under the commercialisation process has led not only to improved efficiency, but also to the reduction of the efficiency gap between the state-owned banks and privately-owned banks. The analysis of efficiency scores (asset transformation) of different forms of banks records a stable trend in estimated efficiency. On the otherhand, estimated MPIs show that Sri Lankan banks have focused on improving productivity in the asset transformation process rather than the intermediationprocess.Analysis of determinants of technical efficiency shows that technical efficiency in intermediation has positive relationships with variables such as profitability,operational risk, purchased funds, liquidity and stock market capitalization; and negative relationships with variables such as product quality and line of business(commercial bank). Further, results show that efficiency in the asset transformation process has positive relationships with capital strength, operational risk, and market capitalisation; and negative relationships with line of business ownership (privately owned banks) and old banks. The investigation of influence of market structure and efficiency on operational performance finds that banks’ relative market power and technical efficiency have a significant influence on their return on assets (ROA). Noevidence supports any relationship of net interest margin with variables such as market power, concentration and efficiency.
