“…Where combined breeding and fattening units exist, Dent (1972) has stressed that the feeding policy in the fattening unit, in so far as it affects throughput, brings into question the balance between investment in the breeding and fattening units. In such an inter-related situation, simulation models are advocated (Blackie and Dent, 1974) for investigating feeding strategy. The ability of such models to describe complex processes in a time framework is not achieved, however, without considerable development and application cost (Clark and McInerney, 1975) which contrasts with the inexpensive analysis permitted by marginal analysis models.…”

This paper examines the way ill which producers of bacon pigs might best adapt their feeding policy to changes in input andproductprices. The approach adopted is to establish aproduction system as apoint of reference and calculate how the profit maximising feeding strategy, defined in terms of diet protein content and feed intake, would vary with changes in feed andproduct prices. Profit per unit time (excluding labour andfixed capital costs) is shown to be rather insensitive to the choice of input levels near the optimum. The benefits from making feeding strategy changes are shown to be small, particularly with respect to diet protein level, but the general approach is considered to have merits for translating technical response data into feeding recommendations.* This is identical to the maximisation of profit per individual pig.

“…The typical farm model allows for evaluation and comparison of the effect of various managerial decisions and options in a cost-and time-efficient way. 53 The typical or representative farm model cannot accurately reflect internal managerial problems for individual, unique farm units. The impact of trends, strategies and policy options on whole-farm profitability can be assessed by using a typical farm.…”

The water-energy-food nexus has emerged as a useful concept to understand the multiple interdependencies that exist between the water, energy and food sectors. The nexus is an ambitious attempt to work across disciplines and scales to understand the workings of these complex systems. It is, however, criticised for being more of a general framework than a practical methodology because of the vast amount of data it would need to make real-life contributions to sustainable development. We show how the nexus approach, when used within a farm budget model, can transform the problem focus in water governance. By changing the relationship among water, energy and food production of a farm, profitability is significantly changed. The water-energy-food nexus debate is discussed within the context of the South African water sector, particularly the Breede River Catchment. Working from within the farm budget model, we demonstrate the impact of moving from an irrigation canal system that requires electricity for pumping, to a gravity-fed piped irrigation system in the Middle Breede River. The finding is that the water-energy-food nexus has the potential to unlock groundbreaking solutions to complex problems in agricultural water management when used in appropriate modelling systems. Significance: The water-energy-food nexus approach can lead to an entirely new framing of water governance problems and therefore solutions to these problems. The water-energy-food nexus when used in farm budget models can identify ways of altering farm profitability. By addressing the energy cost of farming through an irrigation pipeline system in parts of the Breede Catchment Area, farm profitability could significantly increase. A gravity-fed closed pipeline system in parts of the Breede River can improve water availability and reduce farm and management costs.

“…Another major development in relatively recent years has been the work on systems-simulation models (Dent and Anderson, 1971;Anderson, 1974;Dalton, 1975), or packages, for combined planning and control purposesmainly relating to individual livestock enterprises (e.g. Charlton, 1972; Street, 1973;Blackie and Dent, 1974;Ryan, 1974). This particular seam has been well worked and the main interest now lies in waiting to see whether, and to what extent, these models will be used in practice.…”

This review begins by summarising the origins of the subject in the UK and USA. It really ‘took off’ in Britain after 1950. The 1960s witnessed a shift of emphasis by university agricultural economists away from farm management; other organisations established farm management departments. After discussing the present scope of the subject, recent and current research and developments are reviewed. In farm accounting and analysis there have been few changes in the past twenty years, except for electronic data processing. The tremendous interest in and development of farm programming methodology during the 1960s has declined in recent years, with a move towards research with a more immediately practical potential. The systems‐simulation approach, decision analysis and microcomputers have created particular interest. Finally, research areas likely to be of special concern in the future are considered, and the review concludes by discussing the success or otherwise achieved by the subject to date. Résumé LA GESTION DES EXPLOITATIONS AGRICOLES: L'ÉTAT ACTUEL DE CETTE DISCIPLINE Cette étude retrace rapidement l'évolution de cette discipline au Royaume‐Uni et aux Etats‐Unis depuis l'époque où elle prit vraiment son ‘envol’, c'est à dire après 1950 en Grande‐Bretagne. Les années 1960 furent témoins d'un changement d'optique dans l'enseignement universitaire de l'économie agricole, la gestion des exploitations diminuant alors en importance, cependant que certains organismes créaient des sections distinctes pour cette měme discipline. Après un examen de l'étendue actuelle du sujet, Vauteur passe en revue les travaux de recherche récents ou encours et les faits nouveaux enregistrés. Il constate que, dans la comptabilité et l'analyse de la gestion agricole, la situation est restée à peu près la měme depuis une vingtaine d'années, excepté en ce qui concerne l'informatique. Le développement de la méthodologie programmatrice des exploitations agricoles et l'intérět considérable qu'elle avait suscité dans les années 1960 déclinent depuis quelques années au profit de la recherche qui renferme un potentiel pratique plus immédiat. Ont provoqué un intérět particulier la méthode de simulation des systèmes, l'analyse des décisions et les micro‐ordinateurs. Finalement, l'auteur se penche sur les domaines de la recherche qui sont susceptibles de retenir particulièrement l'intérět dans les années futures et il termine par une évaluation de la mesure du succès, si succès il y a, de cette discipline jusqu'à présent.
