“…By following the approach used for the formulation of SAEMETH [26], and already successfully applied by Van Calker et al [31] and by Meul et al [32], the research team tried to mediate the subjectivity of the school garden sustainability components in order to have a framework that allows data collection to be standardized and results to be comparable.…”

School gardens are, increasingly, an integral part of projects aiming to promote nutritional education and environmental sustainability in many countries throughout the world. In the late 1950s, FAO (Food and Agriculture Organization) and UNICEF (United Nations Children's Fund) had already developed projects to improve the dietary intake and behavior through school and community gardens. However, notwithstanding decades of experience, real proof of how these programs contribute to improving sustainability has not been well-documented, and reported findings have mostly been anecdotal. Therefore, it is important to begin a process of collecting and monitoring data to quantify the results and possibly improve their efficiency. This study's primary goal is to propose an interpretive structure-the "Sustainable Agri-Food Evaluation Methodology-Garden" (SAEMETH-G), that is able to quantifiably guide the sustainability evaluation of various school garden organizational forms. As a case study, the methodology was applied to 15 school gardens located in three regions of Kenya, Africa. This application of SAEMETH-G as an assessment tool based on user-friendly indicators demonstrates that it is possible to carry out sustainability evaluations of school gardens through a participatory and interdisciplinary approach. Thus, the hypothesis that the original SAEMETH operative framework could be tested in gardens has also been confirmed. SAEMETH-G is a promising tool that has the potential to help us understand school gardens' sustainability better and to use that knowledge in their further development all over the world.

“…When submodels were published separately from the whole published model of which they were a part, they were retained in our collection only if some characteristics of the submodels, according to our analysis grid, differed significantly from those of the whole model. This was the case for the models presented by Van Calker et al (2004) and Van Calker et al (2007), which were submodels of another published model (Van Calker et al, 2008). When available, publications presenting the model were preferred to those aimed at evaluating this model or at presenting original results obtained from using this model.…”

“…The first one (Van Calker et al, 2007) focuses as a priority on social sustainability and on worker physical health. The purpose of the corresponding publication was to describe certain indicators of worker physical health and of social sustainability that had been selected for incorporation into an existing linear programming model (Van Calker et al, 2004), so as to build a multicriteria model. This pioneer work relied on an intense participation of experts and stakeholders who suggested the attributes to be translated into indicators and who ranked them (Van Calker et al, 2007).…”

Livestock farming has recently come under close scrutiny, in response especially to environmental issues. Farmers are encouraged to redesign their livestock farming systems in depth to improve their sustainability. Assuming that modelling can be a relevant tool to address such systemic changes, we sought to answer the following question: 'How can livestock farming systems be modelled to help farmers redesign their whole farming systems?' To this end, we made a literature review of the models of livestock farming systems published from 2000 to mid-2009 (n 5 79). We used an analysis grid based on three considerations: (i) system definition, (ii) the intended use of the model and (iii) the way in which farmers' decision-making processes were represented and how agricultural experts and farmers were involved in the modelling processes. Consistent rationales in approaches to supporting changes in livestock farming were identified in three different groups of models, covering 83% of the whole set. These could be defined according to (i) the way in which farmers' decisions were represented and (ii) the model's type of contribution to supporting changes. The first type gathered models that dynamically simulated the system according to different management options; the farmers' decision-making processes are assumed to consist in choosing certain values for management factors. Such models allow long-term simulations and endorse different disciplinary viewpoints, but the farmers are weakly involved in their design. Models of the second type can indicate the best combination of farm activities under given constraints, provided the farmers' objectives are profit maximisation. However, when used to support redesigning processes, they address neither how to implement the optimal solution nor its long-term consequences. Models of the third type enable users to dynamically simulate different options for the farming system, the management of which is assumed to be planned according to the farmers' general objectives. Although more comprehensive, these models do not easily integrate different disciplinary viewpoints and different subsystems, which limits their usefulness as support tools for redesigning processes. Finally, we concluded about what specific requirements should be for modelling approaches if farmers were to be supported in redesigning their whole livestock farming systems using models.Keywords: livestock farming systems, modelling, support tools, innovative process, redesign ImplicationsThis review analyses the strengths and weaknesses of published models of livestock farming systems to support farmers in redesigning their whole systems. It is a first step towards building more efficient tools to help farmers to switch towards more sustainable livestock farming systems. IntroductionLivestock farming has recently come under close scrutiny, in response especially to environmental issues (Steinfeld et al., 2006). There is increasing societal pressure for more sustainable livestock practices prompting, for example, the E...

“…Of these, Glithero et al [13], Nakashima [14], and Van Calker et al [19] evaluated GHG emissions as an ecological indicator; however, their analyses did not include rice paddy fields, which are an important source of CH 4 emissions. On the other hand, in Chono et al [11] and Senthilkumar et al [12], only nitrogen was taken into account as a pollutant emitted from rice paddy fields.…”

“…To determine the trade-off between the economic and environmental feasibilities of adopting environmental measures and/or evaluate the economic and environmental impacts of policy changes, previous studies have applied optimization models at the farm scale to rice farms [11,12], arable farms [13,14], arable and livestock farms [15,16], and dairy farms [17][18][19][20]. Of these, Glithero et al [13], Nakashima [14], and Van Calker et al [19] evaluated GHG emissions as an ecological indicator; however, their analyses did not include rice paddy fields, which are an important source of CH 4 emissions.…”

Optimization Model for Mitigating Global Warming at the Farm Scale: An Application to Japanese Rice Farms

Abstract:In Japan, greenhouse gas emissions from rice production, especially CH 4 emissions in rice paddy fields, are the primary contributors to global warming from agriculture. When prolonged midseason drainage for mitigating CH 4 emissions from rice paddy fields is practiced with environmentally friendly rice production based on reduced use of synthetic pesticides and chemical fertilizers, Japanese rice farmers can receive an agri-environmental direct payment. This paper examines the economic and environmental effects of the agri-environmental direct payment on the adoption of a measure to mitigate global warming in Japanese rice farms using a combined application of linear programming and life cycle assessment at the farm scale. Eco-efficiency, which is defined as net farm income divided by global warming potential, is used as an integrated indicator for assessing the economic and environmental feasibilities. The results show that under the current direct payment level, the prolonged midseason drainage technique does not improve the eco-efficiency of Japanese rice farms because the practice of this technique in environmentally friendly rice production causes large economic disadvantages in exchange for small environmental advantages. The direct payment rates for agri-environmental measures should be determined based on the condition that environmentally friendly agricultural practices improve eco-efficiency compared with conventional agriculture.
