Shared Socio-economic Pathways for European agriculture and food systems: The Eur-Agri-SSPs.

ABSTRACT: Scenarios describe plausible and internally consistent views of the future. They can be used by scientists, policymakers and entrepreneurs to explore the challenges of global environmental change given an appropriate level of spatial and sectoral detail and systematic development. We followed a nine-step protocol to extend and enrich a set of global scenarios - the Shared Socio-economic Pathways (SSPs) - providing regional and sectoral detail for European agriculture and food systems using a one-to-one nesting participatory approach. The resulting five Eur-Agri-SSPs are titled (1) Agriculture on sustainable paths, (2) Agriculture on established paths, (3) Agriculture on separated paths, (4) Agriculture on unequal paths, and (5) Agriculture on high-tech paths. They describe alternative plausible qualitative evolutions of multiple drivers of particular importance and high uncertainty for European agriculture and food systems. The added value of the protocol-based storyline development process lies in the conceptual and methodological transparency and rigor; the stakeholder driven selection of the storyline elements; and consistency checks within and between the storylines. Compared to the global SSPs, the five Eur-Agri-SSPs provide rich thematic and regional details and are thus a solid basis for integrated assessments of agriculture and food systems and their response to future socio-economic and environmental changes.

Project description:Persistent food insecurity in the global south has triggered calls for sustainable development worldwide. Moreover, more than a quarter of the world's population suffers from micronutrient deficiencies or hidden hunger. The population bulge, declining soil fertility and inadequate/inappropriate use of farm inputs in Sub-Saharan Africa place it in a precarious position. Multi-nutrient fertilizer blends have been mooted as a key innovation in closing yield gaps and boosting food and nutrition security. This study assessed the extent of multi-nutrient fertilizer blends utilization and yield response across agroecological zones and their on-farm profitability under Kenyan smallholder farmer conditions. We collected data through a detailed household survey conducted in eight counties in Kenya representative of high, medium, and low productivity zones using a sample of 1094 smallholder farmers. Multi-nutrient fertilizers increased maize yields significantly (P < 0.05), eliciting a 400% yield increase compared to the control and 108% greater maize yield than conventional fertilizers in the high potential zone. Conversely, at 3.7 t/ha conventional fertilizers elicited a significant (P < 0.05) yield response in Irish potatoes in the high potential areas. Multi-nutrient fertilizers increased on-farm profitability of crops, specifically for potato production systems where a benefit: cost ratio (BCR) of more than 2 was observed. Farmers may break even when they use multi-nutrient fertilizers on maize particularly in the low potential areas. Therefore, there is considerable potential for multi-nutrient fertilizers to increase crop productivity while being economically viable across agroecological zones and cropping systems. However, the uptake of multi-nutrient fertilizers among farmers is quite low across the country, except for small pockets where limited interventions have been carried out. This calls for sustained efforts to scale multi-nutrient fertilizers with a focus on clear messaging that stresses the need to apply appropriate rates of various nutrients including the secondary nutrients and micro-nutrients.

Project description:Mycobacterium avium ssp. paratuberculosis (MAP) is the causative agent of Johne’s disease (JD), which is also known as paratuberculosis, in ruminants. The mechanisms of JD pathogenesis are still unclear, but it is known that MAP subverts the host immune system for years by using macrophages as its primary reservoir. The effect of MAP infection on macrophages is often studied in healthy or experimentally infected cows, but reports on primary macrophages from naturally infected cows are lacking. In our study, the transcriptome of primary monocyte-derived macrophages challenged with live MAP was analyzed using next-generation sequencing (RNA‑seq). The gene expression signatures of macrophages from cows diagnosed as negative or positive for JD [JD(–) or JD(+), respectively] revealed differential host–pathogen interplay, highlighting long-term mechanisms established during mycobacterial disease. In JD(–) cows, a considerable number of genes (1,436) were differentially expressed at 8 h post-infection (hpi). Interestingly, while expected inflammatory immune response pathways were among the significant pathways, others related to Hepatic fibrosis/hepatic stellate cell activation, lipid homeostasis, such as the LXR/RXR [liver X receptor/retinoid X receptor] activation, and autoimmune diseases such as atherosclerosis and rheumatoid arthritis were consistently among the top significant pathways. Unexpectedly, the macrophages from JD(+) cows did not present a clear response pattern to ex vivo MAP infection, neither during the early period nor at 24 hpi. Analyzing of the transcriptomic profile of the uninfected macrophages, revealed 868 genes that were differentially expressed in JD(+) versus JD(–) cows. The down-regulated genes particularly modified the general cell metabolism by down-regulating amino acid synthesis, cholesterol biosynthesis, and other energy production pathways while introducing a pro-fibrotic pattern associated with foam cells. These modifications show the apparent importance of the metabolic pathways hijacked by MAP to subvert the immune cells. Our findings support the hypothesis that MAP could induce a tolerant-like state in circulating peripheral blood monocytes when they are differentiating into macrophages, which could further promote the persistence. Similar to other mycobacteria and pathogen-associated molecular patterns, MAP could influence macrophage behavior in the long term. This report contributes to a better understanding of MAP control of immune cells and its mechanisms of survival.
