In reviewing them, we find that the bulk of them are from the area of crop sciences, livestock production and allied fields that have used experiments as the research strategy. The minority that falls in to the areas of agribusiness, agricultural economics and extension have used survey strategy. There is a lack of utilizing other research strategies in current research. Research has to be commenced with a clear direction and a clearly identified study process. These are primarily provided by its research strategy (Wedawatta, 2011). There are numerous strategies that a researcher can adopt to achieve the objectives of a particular research study. Some common research strategies are; experiment, survey, archival analysis, ethnography, action research, narrative inquiry, and the case study. This paper explains what a case study is and outlines the components of a case study. The Nature of a Case Study Yin (2003) defines case study as 'an empirical inquiry that investigates a contemporary phenomenon within its real-life context, especially when the boundaries between phenomenon and context are not clearly evident'. A phenomenon and context are not always distinguishable in real-life situations. Therefore, a case study uses a large number of variables of interest than data points; and essentially relies on multiple sources of evidence for data triangulation. A historical viewpoint on case study strategy is presented in Tellis (1997). According to Yin (2003), case studies can be exploratory, explanatory or descriptive. Research in social sciences deals with interactions between institutions and human behaviour. These can be best studied in real-life settings and contexts. Sometimes an inquiry may be undertaken on an individual organization with a limited or a narrow population. These suggest qualitative investigations which are assessments of attitudes, opinions and behaviour (Kothari and Garg, 2018). These qualitative investigations are characteristic with the case study strategy. Whilst often been identified as interpretivist, case studies can also be used in positivistic research (Saunders et al. 2012).

These have been facilitated by state institutions. Maximization of returns through commercial agriculture has been the main objective of FCs. However, no FCs were operating by the year 2010. This article explains that the institutional facilitation is a strong ingredient in the establishment of FCs in Sri Lanka. This article explainfs how the institutional and governance arrangements of FCs were influenced by the facilitating institutions during the institutional facilitation. It also suggests that institutional facilitation affected the performance of FCs. Six failed FCs were studied. Strategic facilitation was responsible for the performance and sustainability of FCs while operative facilitation provided the basis for direction and operations. Results indicate that poor performance and failure of FCs were due to institutional facilitation that has introduced weak institutional a...

But a high post-harvest loss (PHLs) along traditional supply chains and competitiveness of alternative crops are a couple of great challenges on availability of these vegetables. This study estimated PHLs of carrots, cabbage and leeks along the most prominent supply chain from Nuwara-Eliya to Dambulla Dedicated Economic Center followed by an acreage response analysis which has a timely importance. Research Method: The most prominent supply chain in Nuwara-Eliya district which has track record on highest production of up-country vegetables was identifi ed by a pilot test. Multi stage purposive sampling technique was used to track key players and data on estimated PHLs were collected through questionnaire surveys. Acreage response analysis was done by secondary data with the application of Nerlovian expectation model. Findings: Incidence of PHLs of leeks was the highest (44%) and major contributing causes were trimming of lengthier but fresh leaves while bundling followed by mechanical damages. Incidence of PHLs of cabbage was 43% and mainly it was due to trimming of outer leaves. PHLs of carrots (30%) were mainly due to rots and mechanical damages. Acreage response analysis revealed that farmers were responsive to yester year prices of vegetables and potato; an alternative crop. Unit increase of vegetable price can increase the acreage of up-country vegetable by 0.21 hectares while unit increase of potato price can reduce acreage of up-country vegetables by 0.26 hectares. Research Limitations: This study was constrained a little bit by lack of time and logistical limitations. Originality/value: Relationships established between the scale of farming operation and the PHLs was a novel fi nding of this study. PHLs of upcountry vegetables along their common supply chain were also quantifi ed. Policy formulations must be mainly focused on price controlling of vegetable crops to minimize the relative fl uctuations in the extents cultivated and preventing high PHLs which may seriously aff ect food security of the country.

The link between climate change and food security has been mostly explored in relation to impacts on crop production or food availability aspects of food security, with little focus on other key dimensions, namely food access and food utilization. This review, based on available literature, adopted a food system approach to gain a wider perspective on food security issues in Sri Lanka. It points to several climate-induced issues posing challenges for food security. These issues include declining agriculture productivity, food loss along supply chains, low livelihood resilience of the rural poor and prevalence of high levels of undernourishment and child malnutrition. Our review suggests that achieving food security necessitates action beyond building climate resilient food production systems to a holistic approach that is able to ensure climate resilience of the entire food system while addressing nutritional concerns arising from impacts of climate change. Therefore, there is a pressing need to work towards a climate-smart agriculture system that will address all dimensions of food security. With the exception of productivity of a few crop species, our review demonstrates the dearth of research into climate change impacts on Sri Lanka’s food system. Further research is required to understand how changes in climate may affect other components of the food system including productivity of a wider range of food crops, livestock and fisheries, and shed light on the causal pathways of climate-induced nutritional insecurity.

Design/methodology/approach – The study was carried out in the hilly areas of the Badulla district in the Uva Province of Sri Lanka. Primary data were collected through a survey using a researcher-administered questionnaire as the data collection instrument and the individual farmer as the unit of analysis. Findings – Most vegetable farmers in the upcountry areas were found to be attitudinally entrepreneurial. Entrepreneurial attitudes were determined more by educational background and farming experience than age, gender, extent of farmland, type of farming and ownership of farmland. Farming experience related positively with innovation, opportunity seeking and risk taking, but farmers’ educational background...

This paper attempts to identify the market potential for organic vegetables in Sri Lanka, marketing mix strategies and to define variables that can influence purchase decision. Organic farmers in Sri Lanka produce vegetables based on their abilities, resources, products and production processes. Customer orientedness and demand driven production is seldom seen. Poor performance of this product in established outlets is due to poor packaging, inadequate differentiation and lack of reliable certification. Also, customers in Sri Lanka aren't willing to pay a higher price for organic vegetables. Organic growing warrants close contacts with final customers. However, farmers don't meet the final customer and marketing information is conveyed through marketing intermediaries. Customers are concerned about degree of damages, cleanliness, freshness, packaging and convenience at purchasing. Sellers' k...
