9 pages, via online journal, Upland farming in Northwest Cambodia has developed rapidly over the last 20 years, with limitations to the plough based system now apparent, including soil degradation and reductions in yield and profitability. A survey was conducted in order to prioritise the main constraints to production, to aid in future research planning, and to identify potential beneficial modifications to the current system. Three hundred and ninety one farmers were interviewed regarding their current farming system constraints, knowledge of conservation agriculture and their future plans in the Districts of Samlout in Battambang Province and Sala Krau in Pailin Province. Perceived major problems in the farming system were extreme climate events such as droughts and heavy rain, declining crop yields, and cash flow shortages, particularly in the pre-monsoon period. This is a plough based farming system, yet 66% of farmers had heard of conservation agriculture, and 59% wanted to learn more about conservation agriculture practices. Two thirds of farmers were interested in how to grow crops in the post-monsoon dry season on residual soil moisture. The survey highlighted opportunities for farmer education and adoption of farming system modifications to improve productivity and sustainability of the farming system in Northwest Cambodia, and assist with climate change adaptation.
26 pages, via online journal, Purpose
This paper is concerned with the impact of the University of California Cooperative Extension (UCCE) on regional productivity in California agriculture. UCCE is responsible for agricultural research and development (R&D), and dissemination of agricultural know-how in the state.
Method/methodology/approach
We estimate the effect of UCCE on county-level agricultural productivity for the years 1992–2012, using an agricultural production function with measures of agricultural extension inputs alongside the traditional agricultural production inputs at the county level.
Findings
Results show a positive impact of UCCE through its stock of depreciated expenditures. For an additional dollar spent on UCCE expenditures stock, agricultural productivity, measured as value of sales at the county level, improves by $1–9 per acre of farmland for knowledge/expenditure depreciation rates between 0 and 20 percent.
Practical implications
Results suggest that county differences in productivity could affect extension expenditures. The high level of contribution found in the results would be especially useful during a period of political pressure to reduce public spending for agricultural extension in the state.
Theoretical implications
Theoretical implications suggest that agricultural systems with higher level of knowledge depreciation are associated with higher resulting incremental agricultural productivity per an additional dollar spent on UCCE expenditures stock. This suggests that extension policy should consider also the agricultural system (crop mix).
Originality
We use original budgetary data that was collected especially for answering our research questions from archives of UCCE. We estimate impact of extension at the county level in California, on the value of agricultural sales (of crops and livestock). We developed an extension expenditure stock, using current and past expenditures data, and different depreciation rates, following the theory of Knowledge Production Function.
