Diversity and sustainability of pig farm types in the northern mountains of Vietnam.

Pig farming systems in Vietnam are very diverse but little is known about this diversity. In particular, the different livestock farming systems currently in operation do not have the same capacity to be sustainable. The study aims to categorize farming systems involving pig production and investigate their sustainability. Data were collected from 160 family pig farms and 2 large-scale farms in Mai Son district of Son La province (northwest of Vietnam) using stratified random sampling. The multiple factor analysis method was used to identify different farms and to characterize each type with economic, social, and environmental indicators. The results highlighted four different farm types. Type 1 contained smallholder farms with diversified farm activities. They were mainly farmed by ethnic minorities located in the intermediate highland. They had low labor productivity and relied mainly on crop farming. Pig production was characterized by a low level of economic and social sustainability. Type 2 farms had comparatively less land and crops than other types. They were more specialized in livestock production, had medium-size pig herds, and were engaged in off-farm jobs. They were less dependent on credit or location and performed better with regard to environmental issues than larger farm types. Type 3 was specialized farms with large pig herds. They seemed more sustainable in economic and social components than the other types, but their environmental sustainability was questionable. Type 4 contained large mixed crop-livestock farms. They obtained high income but were more dependent on credit than the other types. In the future, in addition to focusing on large-scale specialized farms, policies should also consider small-scale and diversified farms because of their role in the sustainable development of national pig production.

A method for assessing work productivity and flexibility in livestock farms.

Changes affecting livestock farming systems have made farm work a central concern for both the sector and for farmers themselves. Increased pressure on farms to be competitive and productive together with farmers' demand for greater autonomy, holidays or time to spend on private activities and the family converge to underline the two key dimensions of work - productivity and flexibility - required for the assessment of work organization. This paper proposes a method called the QuaeWork (QUAlification and Evaluation of Work in livestock farms) to assess work productivity and flexibility on a farm, and its use to identify how livestock management can contribute to work organization on dairy farms. The QuaeWork method was set up through an iterative process combining surveys conducted with farmers in two regions of France, discussions with different experts and literature review. The QuaeWork was applied on a sample of seven dairy farms in the southern Massif Central in France to identify patterns of how livestock management contributes to work organization. The QuaeWork was used to analyse work organization over the year through a systemic approach to the farm, integrating interactions between herd and land management, workforce composition, equipment facilities and combinations of activities through a characterization of 'who does what, when and for how long'. The criteria for assessing work productivity were work duration (routine work, seasonal work) and work efficiency (per livestock unit or hectare of utilized agricultural area). The criteria for assessing work flexibility were room for manoeuvre and adjustments to internal and external events. The three main patterns of livestock management practices to work organization were identified. In pattern-1, farmers used indoor stable feeding practices with delegated work, with moderate room for manoeuvre and efficiency. In pattern-3, farmers used simplified milking, reproduction and breeding practices to seasonalize work and make it efficient with consistent room for manoeuvre. The method suggests social sustainability criteria to assess work productivity and flexibility, which are important for making reasoned decisions on livestock farm changes, especially innovations. Researchers could usefully exploit the QuaeWork to integrate work objectives (productivity, flexibility) into technical and economic goals.

Involvement of small-scale dairy farms in an industrial supply chain: when production standards meet farm diversity.

In certain contexts, dairy firms are supplied by small-scale family farms. Firms provide a set of technical and economic recommendations meant to help farmers meet their requirements in terms of the quantity and quality of milk collected. This study analyzes how such recommendations may be adopted by studying six farms in Brazil. All farms are beneficiaries of the country's agrarian reforms, but they differ in terms of how they developed their activities, their resources and their milk collection objectives. First, we built a technical and economic benchmark farm based on recommendations from a dairy firm and farmer advisory institutions. Our analysis of the farms' practices and technical and economic results show that none of the farms in the sample apply all of the benchmark recommendations; however, all farms specialized in dairy production observe the main underlying principles with regard to feeding systems and breeding. The decisive factors in whether the benchmark is adopted and successfully implemented are (i) access to the supply chain when a farmer establishes his activity, (ii) a grasp of reproduction and forage production techniques and (iii) an understanding of dairy cattle feed dietary rationing principles. The technical problems observed in some cases impact the farms' dairy performance and cash position; this can lead to a process of disinvestment. This dynamic of farms facing production standards suggests that the diversity of specialized livestock farmers should be taken into account more effectively through advisory approaches that combine basic zootechnical training with assistance in planning farm activities over the short and medium term.
