The role of collaborations in the development and implementation of sustainable livestock concepts in The Netherlands

This paper discusses the role of collaborations in the development and implementation of sustainable livestock farming. The study reflects upon the experiences with two innovative pig farming concepts in the Netherlands that aim to address sustainability-related concerns regarding the economic viability, environmental impact and social responsibility of livestock production. The findings show that collaborations can result in smarter and innovative solutions and provide support in the development of more sustainable farming concepts. The study also shows that collaborations do not safeguard the implementing of these concepts in practice. Pioneers are confronted with higher production costs and the complex context of agricultural policies and regulations. These pioneering efforts are, however, the seeds for change, and the key ingredient for a transition towards more sustainable production. We rely upon their innovations, social networks and learning experiences in the transition towards more sustainable production. Therefore, pioneers need to be protected from market influences and regulatory barriers, and supported by intermediaries when developing novelties for a more sustainable agriculture. The findings emphasize the need for more knowledge exchange and understanding between farmers, policy-makers and researchers to navigate towards a more sustainable agriculture in the future.     

Evolving splines and seasonal unit roots in weekly agricultural prices

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series.     

Organizing women for combat: The experience of the FARC in the Colombian war

The FARC, which used to be Colombia's main guerrilla force and is now in the midst of a peace process, was to a great extent a feminized group. This paper discusses why it recruited so many women, and why it recruited them as combatants. We suggest that only when the FARC adopted a highly hierarchical, self‐contained, and militaristic organizational blueprint did it get involved in the massive recruitment of women as combatants. We discuss the way in which organizational mechanisms and ideology interacted to produce such an outcome, and how this interaction marked both the organization and the trajectories of the women who joined it.     

State‐contingent analysis of farmers’ response to weather variability: irrigated dairy farming in the Murray Valley,Australia

The agricultural sector is commonly regarded as one of the most vulnerable to climate change. Current understanding of the impact of climate change on this sector relies on the underlying assumptions about farmers’ possible responses to weather variability, including changes in crop choice, input combinations and land management practices. Many previous analyses rely on the implicit (and restrictive) assumption that farmers operate under a fixed technology set across different states of nature. This assumption, represented through stochastic production or profit functions, is commonly made but seldom tested and may understate farmers’ responses to climate change if state‐contingent production technologies are, in reality, more flexible. The potential for farmers to adapt production technologies in response to unforeseen events is at the core of the state‐contingent approach. Advanced in Chambers and Quiggin (2000), the theory contends that producers can manage uncertainty through the allocation of productive inputs to different states of nature. In this article, we test the assumption that farmers’ observed behaviour is consistent with the state‐contingent production theory using farm‐level data from Australia. More precisely, we estimate the milk production technology for a sample of irrigated dairy farms from the southern Murray–Darling Basin over the period from 2006–2007 to 2009–2010.     

Spatial determinants of productivity growth on agri‐food Spanish firms: a comparison between cooperatives and investor‐owned firms

This study analyses the effect of the spatial factor, location, and interaction effects among peer companies, on the productivity growth of agri‐food companies in Spain. With this aim, we build a productivity growth index and apply a multiequational Seemingly Unrelated Regression on a sample of 344 Spanish cooperatives and investor‐owned firms for the period 2010–2012. Our findings show that agri‐food firms are influenced by spatial factors finding interesting differences between cooperatives and investor‐owned firms. With regard to the geographical location, cooperatives in the western of Spain show higher productivity growth rates, whereas investor‐owned firms in the northeast of Spain present better results. The interaction effect among closer peer companies is also a relevant factor to determine the productivity growth in agri‐food companies. This factor is more relevant for cooperatives than for investor‐owned firms.     

Is late really better than never? The farmer welfare effects of pineapple adoption in Ghana

Export agriculture offers potentially high returns to smallholder farmers in developing countries, but also carries substantial market risk. In this article we examine the intertemporal welfare impact of the timing of a farmer's entry into the export pineapple market in southern Ghana. We examine whether farmers who never cultivated pineapple are better or worse off than farmers who decided to adopt pineapple earlier or later relative to their peers and experienced a significant adverse market shock several years prior to our endline survey. We use a two‐stage least squares model to estimate the causal effect of duration of pineapple farming on farmer welfare. Consistent with economic theory, we find that earlier adoption of the new crop brings greater welfare gains than does later uptake. But we find that the gains to later uptake of pineapple—just before the market shock—are small in magnitude, just 0.1 standard deviations of a comprehensive asset index, indicating that the gains to adoption may be precarious and depend on the context, in particular on the severity of prospective market shocks.     

Cross-subsidization Due to Inframarginal Support in Agriculture: A General Theory and Empirical Evidence

A general theory of cross-subsidization due to inframarginal support is developed. Two sources of output distortion are identified: exit deterrence and extramarginal output. Some firms would not be in business without the subsidy. Cost savings due to declining average costs are always greater than the losses incurred where price equals marginal cost. Moreover, it is theoretically possible for inframarginal subsidies to expand output more than equivalent fully coupled subsidies. Empirical analysis of U.S. dairy subsidies isolates these components of cross-subsidization and finds distortions from inframarginal support to be substantial, with implications for trade negotiations, dispute settlement, and policy formulation.     

Horticulture,livelihoods, and urban transition in Africa: evidence from South‐West Cameroon

This article documents change in periurban horticulture using repeat surveys in 1995 and 2004 of about 300 households around Muea, Cameroon. Real household incomes increased by 14%, with a large shift from farm to nonfarm income. Within agriculture, activity shifted from staple crops to horticulture, both for sale and in home consumption. In 1995, there were large remittances from farmers involved in periurban horticulture to their village of origin; in 2004 remittances continued and horticultural farmers were also heavily involved in informal financial associations. Periurban horticulture is disproportionately practiced by women and older workers, and plays an important and growing role in African livelihoods.     

Socio‐economic transitions and everyday life changes in the rural world: Pyrenean households and their contemporary economic history

This article focuses on understanding rural life and how agrarian everyday life changes as a consequence of the radical socio‐economic transformations that, across the world, have accompanied rural communities in their transition from economies of subsistence to industrial production, and, in some areas, from there to providers of service to the tourism‐oriented leisure economy. In the last century in the Alt Urgell District (Spanish Pyrenees), many communities went from a production model based on subsistence farming and livestock breeding first to a specialization in milk production and later to tourism. The industrialization of milk production, the radical transformation of the scale of their operations, and the monetization of life transformed the identity and structure of these communities. The subsequent transformation of many of these farms to accommodate the leisure industry changed the shape of these households again. This paper reflects on how science, governance, commodification, and technology played a role on the transformation of the rural mountain areas, their people, and their everyday life.
