CHAPTER 5 DISCUSSION and CONCLUSIONS
5.8 How do the identified complementarities fit relative to prior theoretical frameworks
5.8.2 Classification of system complementarities
Classifying the case studies into different levels of complementarity can be achieved through comparisons to international frameworks. This application of the frameworks to the case studies will be achieved by using three steps or levels of complementarity. These can be divided into organisational, space and time as proposed by Bell and Moore’s (2012) model (section 2.4.5, p.30, figure 11). Each step is outlined in this section with application to the appropriate models and theories.

5.8.2.1 Organisation: Applying system complementarities
Within the case studies, complementary systems were apparent and arose in two ways; vertical integration and diversification. Although vertical integration and diversification were
91 apparent, none of the case studies had only diversified or only vertically integrated. Rather they had used both to meet their key drivers.
According to Sumner and Wolf (2002), diversification mitigates risk through having more than one distinctly marketed output. The case studies highlighted that the spreading of risk was a driver of conversion. The case studies diversified by having milk production and crops for external markets. This included seed crops, vegetable crops, milling wheat, crops sold to other farms for feed and in some cases meat animals such as sheep and steers.
Vertical integration controls risk through ensuring a market (for crops) and ensuring the quality and quantity of fixed inputs (dairy feed). A number of case study farms integrated supplementary feed with the dairy platform so the system did not have to purchase any external feed. Reduced transactions costs arising from this complementarity reflected the existence of scope economies (Villano et al., 2008). The result of economies of scope is greater output at a lower cost per unit of output. Reduced transaction costs according to the case study famers included cartage and commission to agents.
A further driver of conversion was less management stress and increased free time. It can also be suggested that management time is a transaction cost which was reduced through integration; because the farmer no longer had to communicate with the external market. Bell and Moore (2012) described Australian farm business practices in relation to
integration. Their model (figure 11, p. 30) splits the ‘farm business’ into two categories; specialisation and diversification. This categorisation was developed based on the number of farm enterprises in the farm business. For application to the crop-dairy system in Canterbury the model has been revised to include not only the number of enterprises but also the number of final products. This means the ‘farm business’ splits into three categories; specialisation, diversification and vertical integration. A proposed model for Canterbury crop-dairy is outlined in figure 12.

5.8.2.2 Space: Types of system complementarities
Russelle et al.(2007) described two types of integration within a farm business in the scope of space 1) within-farm integration and 2) among-farm integration. What arises from this simplistic differentiation is that complementarity can arise without adjoining or overlapping enterprises in space. The proposed model (figure 12) shows ‘space’ divided into co-location and segregation. Co-location is within-farm integration and segregation includes both
adjoining and separate land parcels when land rotation does not occur. Farmers A and B are examples of segregated farms with no opportunities for rotation due to separate land parcels. However, Farmer A and B still have synergistic relationships through integrated management and knowledge sharing which reduce transaction costs.
5.8.2.3 Time: Type of synergies
Hendrickson et al (2008a) defined integrated production systems as systems that interact in space and time. The case studies provide evidence which emphasises that to achieve
complementarity the level of interaction can vary and space and time do not have to be synchronised.
Case study farmers C, D, E and F have adjoining crop and dairy properties with some levels of spatial separation, rotational integration and fully combined integration as defined by
Hilimare et al (2011). However, none of the farms undertake full rotational or fully combined integration. Within the Canterbury crop-dairy systems, the most applicable definition of ‘fully- combined’ or “synchronised’ is when animals come onto crops post- harvest to graze on a residual. By comparison, rotation integration is when crops and cows occupy the same paddock but at different times. Farmer C notes that the greater returns from dairy are too significant to rotate dairy land for crop. However Farmer C will use rotation by including a crop-cycle in his dairy pasture renewal platform and because his enterprises are adjoining he can then replace the lost dairy area or adapt the size of the dairy platform by taking more land around the outer edges from the crop farm. Farmer D undertook rotational land use by growing 20ha of crop on his 420ha dairy farm but has since increased his herd size and dropped the crop from the dairy platform. Farmer B who does not operate adjoining land parcels grows 20ha of kale on his milking platform for winter feed, an example of rotational integration.
94 Farmers who winter cows on their cropping land undertake rotational integration. Farmer A commented that this rotation is advantageous to his cropping system as animal excrement can reduce fertiliser application.
Farmers C, D, E and F see an ‘advantage’ in their systems gained from the adjoining nature of their enterprises. A reflection of this advantage is their above industry-average milk solid production. These farms all have the ability to expand their milking platforms by grazing pasture or residuals (fully-combined integration) on their cropping farms. Further, using this integration exercise, the farms practice individual drying off and the staggered return of dairy cows to the platform in spring. This reserves the platform for lactating cows only.
