Erskine;Adrian L. D. Paul; Antony van der Ent; Peter D. Erskine;Tropical ultramafic regoliths (derived from iron‑magnesium‑nickel-rich mantle rocks) can yield significant nickel and cobalt ore reserves and are mined across the Asia-Pacific Region. In some instances, ultramafic laterite deposits are also enriched in scandium. However, the behaviour of scandium in soil-plant systems, and any potential geobotanical relationships with economic resources of scandium, have rarely been examined. In this study, we applied biogeochemical prospecting techniques to a known scandium deposit in Central Queensland, Australia. > 80 species originating from 24 families were sampled, all species were typical of semi-arid climate on Ferralsols. Intensive washing with hexane proved to be effective for removing soil contamination. The foliar scandium concentrations were strongly correlated to foliar chromium and aluminium concentrations (likely due to contamination), and two plant specimens had foliar Sc >1 μg g−1 (maximum of 1.46 μg g−1). The usefulness of plant foliar analyses for Sc in biogeochemical prospecting remains unknown.

At the same time, collective place brands are adopted by the public and private sectors in Europe as a strategy to jointly valorize and promote a package of place-specific products and services, which supports a distinctive territorial identity. We hereby present two cases of collective place-branding from France and Morocco, with the objective of comparing them with Geographical Indications and to uncover their potential to contribute to territorial development. Results indicate that collective place brands can be used as an alternative (or complementary) strategy for supporting agricultural and territorial development. Contrary to GIs, these brands represent an integrated approach to territorial development, involve various local actors, are more flexible in use and less subjected to legal and administrative rules. They can create synergy effects and increase the overall visibility of places and their endogenous assets. On the other hand, collective place brands need leadership and cooperation in order to be successful. Moreover, collective place brands require a long-term commitment from the public and private sector for inducing novel forms of territorial governance.

Intercropping is a strategy for increasing agricultural productivity per unit land that is based on ecological mechanisms for improved resource capture. No quantitative synthesis has been made on the effect of intercrop system properties and species trait combinations on intercrop productivity. Here we use meta-analysis of the intercropping literature to study how the productivity of mixed systems is affected by intercrop system design and species traits. We focus on the effects of temporal niche differentiation between species, intercropping pattern, relative densities, the use of C3 and C4 species and the rate of nitrogen fertilizer. Land equivalent ratio (LER) is used as index for assessing the relative productivity of a mixed system as compared to sole crops. Average LER was 1.22 ± 0.02, and no differences in LER were found between the 50 most highly cited studies and a random sample from the literature, indicating that high LERs in highly cited papers are representative of the entire literature. Temporal niche differentiation contributed substantially to high LER in systems combining a C3 and C4 species, but not in systems based on C3 species mixtures. The amount of N fertilizer interacted positively with the effect of temporal niche differentiation on LER. The intercropping literature is dominated by studies on cereal/legume mixtures. However, the few studies on C3 cereal/C4 cereal mixtures indicate these mixtures have high LER. Substantial improvements in land use efficiency in agriculture may be obtained by using mixtures, particularly C3/C4 mixtures. Thus, enhanced within-field crop diversity can make an important contribution to sustainable increases in food production.

International audience; Phytomining technology employs hyperaccumulator plants to take up metal in harvestable plant biomass. Harvesting, drying and incineration of the biomass generates a high-grade bio-ore. We propose that ``agromining'' (a variant of phytomining) could provide local communities with an alternative type of agriculture on degraded lands; farming not for food crops, but for metals such as nickel (Ni). However, two decades after its inception and numerous successful experiments, commercial phytomining has not yet become a reality. To build the case for the minerals industry, a large-scale demonstration is needed to identify operational risks and provide ``real-life'' evidence for profitability.

Since a few decades, several research teams around the world carry out a huge work to model the future climatic change during the 21st century, based on several scenarios of greenhouse gas emission. We have to expect rise in average temperatures, in atmospheric CO2 concentration, in soil salinity in some areas, and lower and more irregular rainfall. The climate variability and the frequency of extreme events (scorching heat, heavy rainfall, drought, hurricane) are also expected to rise. Climate change is therefore a great concern for agriculture. Mango is one of the most widely cultivated and popular fruits in these regions for its economic and nutritional values. It is the fifth most cultivated fruit in the world. It is consequently justified to wonder about the impact of climate change on the mango tree and about the consequences on mango production and cultivation. The lack of crop model for mango prevents the prediction of the effects of climate change on mango tree development and production. They are then assessed on the basis of our current knowledge on the influence of climatic variables on mango tree development and production. We describe the influence of climatic variables on processes of agronomical importance for the mango tree: photosynthesis, vegetative and reproductive development, fruit quality. We then review the climate changes predicted for two areas of mango production and draw the possible consequences for mango cultivation. Finally, we propose some research ways to adapt mango cultivation to climate change in the coming decades, such as cultivar and rootstock selection, and improvement of cultural practices. The interest of developing a mango crop model is discussed.

H.; Ratnadass, Alain; Ricci, Pierre; Sarah, Jean-Louis; Messean, Antoine;Agriculture faces the challenge of meeting increasing food demands whilst simultaneously satisfying ever stringent sustainability goals. Taken together with the ever increasing rate of integrated globalisation and other anthropogenic impacts, this challenge is further complicated by climate change. Climate change is indeed increasingly recognised as a considerable risk to agriculture in the European Union, particularly with respect to direct impacts on crop production and yield stability. A major impact threat is the further risk from new and emerging invasive alien species, and potential novel pathogenically aggressive adaptations in existing indigenous pests and pathogens, which, hitherto, have been managed with conventional practices and approaches. The introduction of several exotic pests such as Tuta absoluta, Bemisia tabaci, and Bactrocera fruit flies in Europe points out the changing trend in pathogen adaptation to new regions due to climate change thereby threatening the viability of European crop production. Likewise, slight increases in temperature heighten disease severity caused by indigenous pathogens such as Leptosphaeria maculans, Fusarium graminearum and Dickeya spp. on oilseed rape, cereals and potato, respectively in Europe. Over the last century, there has been an increased global mean temperature by 0.74 degrees C which is projected to rise by 3.4 degrees C by the end of twenty-first century. This raise in temperature has resulted in increased pest pressure in European agriculture through a shift from lower latitudes pole-wards and from lower to higher altitudes. In view of this, the development of anticipatory adaptive strategies, resulting in more resilient cropping systems, is the only alternative to tackle evolving pests under changing climate in order to ensure food security for a global population estimated to reach 9.6 billion by 2050.

J.; Foegeding, Allen E; Windhab, Erich J.; Perrot, Nathalie; van Der Linden, Erik;The quality and amount of the world food supply is crucial to the well-being of every human on the planet in the basic sense that we need food to live. It also has a profound impact on world economy, international trade, and global political stability. The choice of land used for agriculture, and the livestock and plants raised on the land, will impact the sustainable use of global resources. On a global scale, there are communities where insufficient food causes nutritional deficiencies, and at the same time, there are other communities eating too much food leading to obesity. Both conditions have accompanying diseases with associated financial consequences. The above issues relate to various scales, from local to global, and to a range of scientific disciplines. Moreover, their various elements are part of an interdependent, continuously changing, and adaptive system. This implies that the response of a combination of individual elements cannot usually be inferred from the response of each individual element or subsystem. This makes the identification of an appropriate intervention to change one or more elements a complex problem. We propose that a complex system approach should be used to address the global challenges of the agriculture and food system. The complex system approach accounts for the needs of stakeholders and policymakers in the agriculture and food system, and helps to determine which research programs will enable stakeholders to better anticipate and respond to emerging developments in the world. Moreover, the approach will enable them to determine effective intervention strategies to simultaneously optimise and safeguard their interests and the interests of the environment. The approach is formulated in terms of a roadmap of procedures. It encompasses an array of methods utilised in an integrative multi-scale and inter-disciplinary way.

Changes in the (12)C/(13)C ratio (expressed as δ(13)C) of soil organic C (SOC) has been observed over long time scales and with depth in soil profiles. The changes are ascribed to the different reaction kinetics of (12)C and (13)C isotopes and the different isotopic composition of various SOC pool components. However, experimental verification of the subtle isotopic shifts associated with SOC turnover under field conditions is scarce. We determined δ(13)C and SOC in soil sampled during 1929-2009 in the Ap-horizon of five European long-term bare fallow experiments kept without C inputs for 27-80 years and covering a latitudinal range of 11°. The bare fallow soils lost 33-65% of their initial SOC content and showed a mean annual δ(13)C increase of 0.008-0.024‰. The (13)C enrichment could be related empirically to SOC losses by a Rayleigh distillation equation. A more complex mechanistic relationship was also examined. The overall estimate of the fractionation coefficient (ε) was -1.2 ± 0.3‰. This coefficient represents an important input to studies of long-term SOC dynamics in agricultural soils that are based on variations in (13)C natural abundance. The variance of ε may be ascribed to site characteristics not disclosed in our study, but the very similar kinetics measured across our five experimental sites suggest that overall site-specific factors (including climate) had a marginal influence and that it may be possible to isolate a general mechanism causing the enrichment, although pre-fallow land use may have some impact on isotope abundance and fractionation.

It involves the mobilization of territorial resources by individual or collective actors (Gumuchian and Pecqueur 2007). These resources can either be physical – abundant natural resources, favorable climatic conditions or very good market access, etc. – or intangible – traditional and ancestral know-how, political resources, cultural heritage, etc. The appropriation and use of these resources reveal strategies of action of various stakeholders. Thus territorial dynamics can be defined as changes and translations, in a given area, of individual or collective actions planned and undertaken for the appropriation and use of limited resources, in specific institutional and political contexts (Piraux 2009). This chapter aims at evaluating the contribution of family farming models, as the sum of individual and collective actors, to these territorial dynamics.

Rufino; Jonathan Vayssières; Paulo Salgado; Pablo Tittonell; Emmanuel Tillard; François Bocquier;Abstract Food insecurity, soil fertility depletion and strong competition for biomass are commonly observed in smallholder crop-livestock systems. The objective of this study was to explore options to improve farm-level nitrogen cycling, productivity and economic performance through the analysis of N flows within four contrasting crop-livestock farm systems of Madagascar highlands. Farms were conceptualized as networks where the compartments were the household and their farming activities, all connected by N flows. Indicators assessing network size and cycling, and the organization and diversity of the N flows, were compared with system productivity, food self-sufficiency, and gross margins for the current situation and under four scenarios of intensification (i) dairy production increased by increasing N inputs as supplementary feed; (ii) crop production increased by increasing N inputs as mineral fertilizer; (iii) manure management improved to increase N conservation during storage and application to soils; (iv) a combination of the two most economically attractive scenarios (i and iii). The four case study farms represent local diversity differing widely in terms of network size, with total annual system N throughput ranging from 113 to 1037 kg N per capita, and in terms of N cycling, from 3 to 41 kg N per capita per year. They differed less in terms of external dependence, from 0.26 to 0.41 kg N kg N −1 . Improving N conservation through improved manure management (scenario iii) had a positive impact on gross margin, and this in combination with increased concentrate supply (scenario iv) led to increases in whole-farm N use efficiencies from 2% to 50%, in N cycling from 9% to 68% and in food self-sufficiency from 12% to 37% across farm types. Gross margin was the most sensitive indicator to changes in management. Intensification through scenario iv had the highest impact on farm productivity, gross margin, food self-sufficiency, and environment sustainability (N use efficiency, capacity of the soil to stock N).

Erskine;Adrian L. D. Paul; Antony van der Ent; Peter D. Erskine;Tropical ultramafic regoliths (derived from iron‑magnesium‑nickel-rich mantle rocks) can yield significant nickel and cobalt ore reserves and are mined across the Asia-Pacific Region. In some instances, ultramafic laterite deposits are also enriched in scandium. However, the behaviour of scandium in soil-plant systems, and any potential geobotanical relationships with economic resources of scandium, have rarely been examined. In this study, we applied biogeochemical prospecting techniques to a known scandium deposit in Central Queensland, Australia. > 80 species originating from 24 families were sampled, all species were typical of semi-arid climate on Ferralsols. Intensive washing with hexane proved to be effective for removing soil contamination. The foliar scandium concentrations were strongly correlated to foliar chromium and aluminium concentrations (likely due to contamination), and two plant specimens had foliar Sc >1 μg g−1 (maximum of 1.46 μg g−1). The usefulness of plant foliar analyses for Sc in biogeochemical prospecting remains unknown.

At the same time, collective place brands are adopted by the public and private sectors in Europe as a strategy to jointly valorize and promote a package of place-specific products and services, which supports a distinctive territorial identity. We hereby present two cases of collective place-branding from France and Morocco, with the objective of comparing them with Geographical Indications and to uncover their potential to contribute to territorial development. Results indicate that collective place brands can be used as an alternative (or complementary) strategy for supporting agricultural and territorial development. Contrary to GIs, these brands represent an integrated approach to territorial development, involve various local actors, are more flexible in use and less subjected to legal and administrative rules. They can create synergy effects and increase the overall visibility of places and their endogenous assets. On the other hand, collective place brands need leadership and cooperation in order to be successful. Moreover, collective place brands require a long-term commitment from the public and private sector for inducing novel forms of territorial governance.

Intercropping is a strategy for increasing agricultural productivity per unit land that is based on ecological mechanisms for improved resource capture. No quantitative synthesis has been made on the effect of intercrop system properties and species trait combinations on intercrop productivity. Here we use meta-analysis of the intercropping literature to study how the productivity of mixed systems is affected by intercrop system design and species traits. We focus on the effects of temporal niche differentiation between species, intercropping pattern, relative densities, the use of C3 and C4 species and the rate of nitrogen fertilizer. Land equivalent ratio (LER) is used as index for assessing the relative productivity of a mixed system as compared to sole crops. Average LER was 1.22 ± 0.02, and no differences in LER were found between the 50 most highly cited studies and a random sample from the literature, indicating that high LERs in highly cited papers are representative of the entire literature. Temporal niche differentiation contributed substantially to high LER in systems combining a C3 and C4 species, but not in systems based on C3 species mixtures. The amount of N fertilizer interacted positively with the effect of temporal niche differentiation on LER. The intercropping literature is dominated by studies on cereal/legume mixtures. However, the few studies on C3 cereal/C4 cereal mixtures indicate these mixtures have high LER. Substantial improvements in land use efficiency in agriculture may be obtained by using mixtures, particularly C3/C4 mixtures. Thus, enhanced within-field crop diversity can make an important contribution to sustainable increases in food production.

International audience; Phytomining technology employs hyperaccumulator plants to take up metal in harvestable plant biomass. Harvesting, drying and incineration of the biomass generates a high-grade bio-ore. We propose that ``agromining'' (a variant of phytomining) could provide local communities with an alternative type of agriculture on degraded lands; farming not for food crops, but for metals such as nickel (Ni). However, two decades after its inception and numerous successful experiments, commercial phytomining has not yet become a reality. To build the case for the minerals industry, a large-scale demonstration is needed to identify operational risks and provide ``real-life'' evidence for profitability.

Since a few decades, several research teams around the world carry out a huge work to model the future climatic change during the 21st century, based on several scenarios of greenhouse gas emission. We have to expect rise in average temperatures, in atmospheric CO2 concentration, in soil salinity in some areas, and lower and more irregular rainfall. The climate variability and the frequency of extreme events (scorching heat, heavy rainfall, drought, hurricane) are also expected to rise. Climate change is therefore a great concern for agriculture. Mango is one of the most widely cultivated and popular fruits in these regions for its economic and nutritional values. It is the fifth most cultivated fruit in the world. It is consequently justified to wonder about the impact of climate change on the mango tree and about the consequences on mango production and cultivation. The lack of crop model for mango prevents the prediction of the effects of climate change on mango tree development and production. They are then assessed on the basis of our current knowledge on the influence of climatic variables on mango tree development and production. We describe the influence of climatic variables on processes of agronomical importance for the mango tree: photosynthesis, vegetative and reproductive development, fruit quality. We then review the climate changes predicted for two areas of mango production and draw the possible consequences for mango cultivation. Finally, we propose some research ways to adapt mango cultivation to climate change in the coming decades, such as cultivar and rootstock selection, and improvement of cultural practices. The interest of developing a mango crop model is discussed.

H.; Ratnadass, Alain; Ricci, Pierre; Sarah, Jean-Louis; Messean, Antoine;Agriculture faces the challenge of meeting increasing food demands whilst simultaneously satisfying ever stringent sustainability goals. Taken together with the ever increasing rate of integrated globalisation and other anthropogenic impacts, this challenge is further complicated by climate change. Climate change is indeed increasingly recognised as a considerable risk to agriculture in the European Union, particularly with respect to direct impacts on crop production and yield stability. A major impact threat is the further risk from new and emerging invasive alien species, and potential novel pathogenically aggressive adaptations in existing indigenous pests and pathogens, which, hitherto, have been managed with conventional practices and approaches. The introduction of several exotic pests such as Tuta absoluta, Bemisia tabaci, and Bactrocera fruit flies in Europe points out the changing trend in pathogen adaptation to new regions due to climate change thereby threatening the viability of European crop production. Likewise, slight increases in temperature heighten disease severity caused by indigenous pathogens such as Leptosphaeria maculans, Fusarium graminearum and Dickeya spp. on oilseed rape, cereals and potato, respectively in Europe. Over the last century, there has been an increased global mean temperature by 0.74 degrees C which is projected to rise by 3.4 degrees C by the end of twenty-first century. This raise in temperature has resulted in increased pest pressure in European agriculture through a shift from lower latitudes pole-wards and from lower to higher altitudes. In view of this, the development of anticipatory adaptive strategies, resulting in more resilient cropping systems, is the only alternative to tackle evolving pests under changing climate in order to ensure food security for a global population estimated to reach 9.6 billion by 2050.

J.; Foegeding, Allen E; Windhab, Erich J.; Perrot, Nathalie; van Der Linden, Erik;The quality and amount of the world food supply is crucial to the well-being of every human on the planet in the basic sense that we need food to live. It also has a profound impact on world economy, international trade, and global political stability. The choice of land used for agriculture, and the livestock and plants raised on the land, will impact the sustainable use of global resources. On a global scale, there are communities where insufficient food causes nutritional deficiencies, and at the same time, there are other communities eating too much food leading to obesity. Both conditions have accompanying diseases with associated financial consequences. The above issues relate to various scales, from local to global, and to a range of scientific disciplines. Moreover, their various elements are part of an interdependent, continuously changing, and adaptive system. This implies that the response of a combination of individual elements cannot usually be inferred from the response of each individual element or subsystem. This makes the identification of an appropriate intervention to change one or more elements a complex problem. We propose that a complex system approach should be used to address the global challenges of the agriculture and food system. The complex system approach accounts for the needs of stakeholders and policymakers in the agriculture and food system, and helps to determine which research programs will enable stakeholders to better anticipate and respond to emerging developments in the world. Moreover, the approach will enable them to determine effective intervention strategies to simultaneously optimise and safeguard their interests and the interests of the environment. The approach is formulated in terms of a roadmap of procedures. It encompasses an array of methods utilised in an integrative multi-scale and inter-disciplinary way.

Changes in the (12)C/(13)C ratio (expressed as δ(13)C) of soil organic C (SOC) has been observed over long time scales and with depth in soil profiles. The changes are ascribed to the different reaction kinetics of (12)C and (13)C isotopes and the different isotopic composition of various SOC pool components. However, experimental verification of the subtle isotopic shifts associated with SOC turnover under field conditions is scarce. We determined δ(13)C and SOC in soil sampled during 1929-2009 in the Ap-horizon of five European long-term bare fallow experiments kept without C inputs for 27-80 years and covering a latitudinal range of 11°. The bare fallow soils lost 33-65% of their initial SOC content and showed a mean annual δ(13)C increase of 0.008-0.024‰. The (13)C enrichment could be related empirically to SOC losses by a Rayleigh distillation equation. A more complex mechanistic relationship was also examined. The overall estimate of the fractionation coefficient (ε) was -1.2 ± 0.3‰. This coefficient represents an important input to studies of long-term SOC dynamics in agricultural soils that are based on variations in (13)C natural abundance. The variance of ε may be ascribed to site characteristics not disclosed in our study, but the very similar kinetics measured across our five experimental sites suggest that overall site-specific factors (including climate) had a marginal influence and that it may be possible to isolate a general mechanism causing the enrichment, although pre-fallow land use may have some impact on isotope abundance and fractionation.

It involves the mobilization of territorial resources by individual or collective actors (Gumuchian and Pecqueur 2007). These resources can either be physical – abundant natural resources, favorable climatic conditions or very good market access, etc. – or intangible – traditional and ancestral know-how, political resources, cultural heritage, etc. The appropriation and use of these resources reveal strategies of action of various stakeholders. Thus territorial dynamics can be defined as changes and translations, in a given area, of individual or collective actions planned and undertaken for the appropriation and use of limited resources, in specific institutional and political contexts (Piraux 2009). This chapter aims at evaluating the contribution of family farming models, as the sum of individual and collective actors, to these territorial dynamics.

Rufino; Jonathan Vayssières; Paulo Salgado; Pablo Tittonell; Emmanuel Tillard; François Bocquier;Abstract Food insecurity, soil fertility depletion and strong competition for biomass are commonly observed in smallholder crop-livestock systems. The objective of this study was to explore options to improve farm-level nitrogen cycling, productivity and economic performance through the analysis of N flows within four contrasting crop-livestock farm systems of Madagascar highlands. Farms were conceptualized as networks where the compartments were the household and their farming activities, all connected by N flows. Indicators assessing network size and cycling, and the organization and diversity of the N flows, were compared with system productivity, food self-sufficiency, and gross margins for the current situation and under four scenarios of intensification (i) dairy production increased by increasing N inputs as supplementary feed; (ii) crop production increased by increasing N inputs as mineral fertilizer; (iii) manure management improved to increase N conservation during storage and application to soils; (iv) a combination of the two most economically attractive scenarios (i and iii). The four case study farms represent local diversity differing widely in terms of network size, with total annual system N throughput ranging from 113 to 1037 kg N per capita, and in terms of N cycling, from 3 to 41 kg N per capita per year. They differed less in terms of external dependence, from 0.26 to 0.41 kg N kg N −1 . Improving N conservation through improved manure management (scenario iii) had a positive impact on gross margin, and this in combination with increased concentrate supply (scenario iv) led to increases in whole-farm N use efficiencies from 2% to 50%, in N cycling from 9% to 68% and in food self-sufficiency from 12% to 37% across farm types. Gross margin was the most sensitive indicator to changes in management. Intensification through scenario iv had the highest impact on farm productivity, gross margin, food self-sufficiency, and environment sustainability (N use efficiency, capacity of the soil to stock N).
