General economic forces acting upon structural change in agriculture dominate the impacts of changes in agricultural policy. Particular factors are: (1) High demand for land for nonagricultural purposes. (2) High demand for residences in rural areas. (3) Demand for leisure space. (4) Changing occupational expectations and a move away from physical labour. Structural adjustment in agriculture is a steady process, driven by the enlargement of commercial farms and by the marginalisation of large numbers of smaller farms whose managers increasingly rely on off farm income and part-time operation. The most heavily commercial sector is becoming less dependent upon traditional support and more heavily influenced by the integrated contracts with downstream...

A majority of UK dairy herds have the potential to increase profitability by improving the ration of their cows. This paper reports that gains averaging around £100 per cow have been made within one year of adopting the Keenan Hi-Fibre ration by 239 UK herds in 2006 and 2007. Larger gains have been made by herds in France. The key performance indicator underlying these gains is Feed Conversion Efficiency, whereby the same, or even a smaller amount of Dry Matter Intake generates higher yields per cow. Importantly, the gains are associated with large improvements in animal health and reductions in greenhouse gases per litre of milk produced.

Agriculture's Terms of Trade: Issues and Implications

This paper classifies methods for estimating agricultural output supply responses to price into two broad categories (1) programming and (2) econometric. The latter category is further subdivided into two-stage procedures, directly estimated supply systems and directly estimated single commodity models. In Part 1 the theoretical basis of these methods is considered, while Part 2 explores their strengths, weaknesses and potentials from an empirical standpoint.
