“…Multiple studies including life cycle analyses have been conducted in different parts of the world to assess the GWPs based on the regional data. The GWPs can vary widely based on agricultural practices, availability of irrigation systems, fertilizer applications, availability and mode of transportation as all these factors play a role in GHGs released into the atmosphere (Table 5) [11,[41][42][43][44][45][46][47][48][49]. Carbon equivalent emission (CEE) is just a measure of total carbon equivalents calculated based on the GWP (which is the CO 2 equivalents).…”

By the end of this century, the average global temperature is predicted to rise due to the increasing release of greenhouse gases (GHGs) into the atmosphere. This change in climate can reduce agricultural yields, resulting in food insecurity. However, agricultural activities are one of the major contributors of GHGs and lower yields can trigger increased activity to meet the demand for food, resulting in higher quantities of GHGs released into the atmosphere. In this paper, we discuss the growth requirements and greenhouse gas release potential of staple cereal crops and assess the impact of climate change on their yields. Potential solutions for minimizing the influence of climate change on crop productivity are discussed. These include breeding to obtain cereals that are more tolerant to conditions caused by climate change, increased production of these new cultivars, improved irrigation, and more effective use of fertilizers. Furthermore, different predictive models inferred that climate change would reduce production of major cereal crops, except for millets due to their ability to grow in variable climatic conditions, and in dry areas due to a strong root system. Moreover, millets are not resource-intensive crops and release fewer greenhouse gases compared to other cereals. Therefore, in addition to addressing food security, millets have an enormous potential use for reducing the impact of agriculture on global warming and should be grown on a global scale as an alternative to major cereals and grains.

Current assessment tools are mainly disciplinary and support the assessment of material flows in terms of environmental impacts or economical flows, for example. These tools provide helpful quantitative information for system (re)-design but do not explicitly question the value creation factors and their embeddedness in a specific socio-spatial context. This article underlines that innovation for sustainability requires more complexity and a system and multidisciplinary approach. A dynamic material and immaterial resource flows model coupled with extended scorecard to support both the analysis and structuration of territorial projects may be of great support to better understand, qualify and quantify the different kinds of resources revealed, mobilized or denied during a project. This communication focuses on the model development and the cross-fertilization of industrial, sociological and geographical disciplines for system transition analysis. Even if this model is still under development, it appears to strengthen strategic analysis, as it enables both the representation of the tangibles and intangible assets mobilized during the emergence and structuration of territorial projects (e.g. business model transition to functional economy) and sustainability assessment of existing projects (e.g. industrial and territorial ecology projects).

“…wheat production), the components of the production stage (soil N 2 O, ammonia, and NO x emissions from the use of nitrogen fertiliser; air emissions from the combustion of fuels such as diesel and natural gas; nutrient accumulation in water bodies due to the loss of N and P fertiliser; toxic effects from the application of pesticides; water use for irrigation; and land occupation) are usually taken into consideration. 24,69,73 However, there are still outside emissions, which affect the agricultural production in the system boundary. This is a difference between LCA for general consumer and industrial goods, and LCA for food and agriculture products.…”

“…LCA is a method still under development and much research is being conducted worldwide in order to improve methodological issues [i.e. life cycle inventory (LCI) databases, life cycle impact assessment (LCIA) methodology] and its effectiveness in/during application . It is also important to note that in the last decade, several research papers on improving methodological issues have been published, such as the development of consequential LCA methods and approaches, which seek an environmental assessment that takes the evaluation a step further, and describes how relevant environmental flows will be changed as a result of possible decisions, linking LCA with spatial modelling and mapping techniques in agriculture and energy crops environmental assessments .…”
