Effect of Farm-Level Constraints, Existing and Prospective Policies on Expansion of Coconut-Based Intercropping in Sri Lanka AgEcon
Fernando, Neil; Edwards, Ian E.; Thomson, Kenneth J.; Daw, Mike.
Coconut-based intercropping (CBI) in Sri Lanka was introduced some 20 years ago to overcome the two main limitations of traditional coconut monocropping, inefficient land use and low incomes to farmers, but it has not been widely adopted. This study analyses the effect of farm-level resource constraints, and government policies on the intensity of adoption of CBI. A multiperiod linear programming (MLP) model was applied for three farmer groups - resource poor, medium endowed, well endowed - categorised using cluster analysis. Data was collected from a survey of randomly selected 113 intercroppers. Empirical results reveal that expansion of CBI is mainly constrained by seasonal labour shortages for all farmer groups, particularly the well endowed, and by...

The Costs and Returns of Scottish Potato Production AgEcon
Edwards, Ian E.; Daw, Mike.
The gross and net margins for a representative sample of 53 Scottish potato producers classed as "Seed" (>80% of area grown for seed), "Ware" (>80% of area grown for Ware) and "Mixed" for the rest were obtained for the 1999 growing season according to the methodology of MAFF (1990,1999). The farms were arable. Yields were average but for seed growers for whom tuber number in the seed size is more important. Prices were the lowest for six years variable costs were high and gross margins are above the best for cereals. However fixed costs excluding seasonally rented land are considerable leaving negative net margins. Potato price fluctuates widely. Prices were high in 1998. Applying these prices to the 1999 data left good net margins. Average prices...

The Profitability of Conversion to Organic Farming Systems AgEcon
Edwards, Ian E.; Roberston, Jamie.
The management accounts in Farm Account Scheme (FAS) format of two Scottish farms in Organic conversion are examined and compared to Scottish average data. Farm 1 is a family run mixed farm with cereals, seed potatoes, cattle and sheep. Conversion has been phased with conversion ground in grass and set-aside, while cereals and potatoes have been grown conventionally until they could be grown organically. Cereal area was reduced so that livestock numbers and potato area could be maintained. The phased conversion plus organic aid payments has maintained the above average profitability although good prices for organic malting barley and seed potatoes have helped but these premiums may not be maintained. Farm 2 is an all grass dairy farm with two 150 cow...

Labour Management for Profit and Welfare in Extensive Sheep Farming AgEcon
Kirwan, Susanne; Thomson, Kenneth J.; Edwards, Ian E.; Stott, Alistair W..
Sheep welfare is an emerging topic in research and food marketing, and recent studies suggest that farm labour is a key factor for both animal welfare and productivity in extensive sheep farming systems, although little research has been done into labour utilisation in these systems. This paper reports field data collection on two commercial farms and the use of a linear programming (LP) model to link labour economics and animal welfare analysis. The model maximises the number of ewes to clooked after over the lambing period, when constrained by labour availability for various key tasks and by a pre-determined level of sheep welfare. The results show a trade-off between welfare level and labour input per sheep. Dropping tasks with less significant welfare...
