This paper offers a systematic analysis of the concepts and contexts that frame climate-smart agriculture (CSA) discourse in academic policy literature. Documents (n = 113) related to CSA published peer-reviewed journals, books, working papers, scientific reports from 2004 2016 were reviewed. Three key trends emerged analysis: studies are biased towards global agendas; research focuses on technical issues; integration mitigation, adaptation, food security (the three pillars CSA) is becoming popular scholarly solution. Findings suggest fairly new concept used describe range adaptation mitigation practices without specific set criteria. Although often framed around pillars, underlying issues constructing differ at global, developing, developed country scales. there increasing developing countries, particularly relation how can transform smallholder agriculture, paucity documenting experiences countries.

Well-designed and supported innovation niches may facilitate transitions towards sustainable agricultural futures, which follow different approaches paradigms such as agroecology, local place-based food systems, vertical farming, bioeconomy, urban agriculture, smart farming or digital farming. In this paper we consider how the existing systems (AIS) approach might be opened up to better support creation of niches. We engage with Innovation Ecosystems thinking ways in it enhance efforts create multi-actor, cross-sectoral that are capable supporting across multiple scales. While sharing many similarities AIS thinking, has potential broaden by: emphasizing role power shaping directionality platforms communities connected their interaction regimes; highlighting plurality actors actants integral ecological innovation; offering an umbrella concept through cross scalar paradigmatic sector boundaries order a variety affecting multifunctional landscapes systems. To end, Agricultural help design development transboundary, inter-sectoral can realize more collective integrated sustainability transitions, enact mission oriented policy.

Abstract Oxidation of ammonia to nitrite by bacteria and archaea is responsible for global emissions nitrous oxide directly indirectly through provision and, after further oxidation, nitrate denitrifiers. Their contributions increasing N 2 O are greatest in terrestrial environments, due the dramatic continuing increases use ammonia‐based fertilizers, which have been driven requirement increased food production, but also provide a source energy oxidizers (AO), leading an imbalance nitrogen cycle. Direct production AO results from several metabolic processes, sometimes combined with abiotic reactions. Physiological characteristics, including mechanisms vary within between ammonia‐oxidizing (AOA) (AOB) comammox yield AOB higher than other two groups. There strong evidence niche differentiation AOA respect environmental conditions natural engineered environments. In particular, favored low soil pH are, respectively, rates ammonium supply, equivalent application slow‐release fertilizer, or high addition concentrations inorganic urea. These differences potential better fertilization strategies that could both increase fertilizer efficiency reduce agricultural soils. This article reviews research on biochemistry, physiology ecology discusses consequences communities subjected different practices ways this knowledge, coupled improved methods characterizing communities, might lead mitigation emissions.

Abstract Safeguarding river ecosystems is a precondition for attaining the UN Sustainable Development Goals (SDGs) related to water and environment, while rigid implementation of such policies may hamper achievement food security. River provide life-supporting functions that depend on maintaining environmental flow requirements (EFRs). Here we establish gridded process-based estimates EFRs their violation through human withdrawals. Results indicate 41% current global irrigation use (997 km 3 per year) occurs at expense EFRs. If these volumes were be reallocated ecosystems, half globally irrigated cropland would face production losses ≥10%, with ∼20–30% total country especially in Central South Asia. However, explicitly show improvement practices can widely compensate sustainable basis. Integration rainwater management even achieve 10% net gain. Such interventions are highlighted act as pivotal target supporting ambitious seemingly conflicting SDG agenda.

Abstract The concepts of food security and sustainability are two main paradigms in the system discourse—however, they often addressed separately scientific literature. We argue that this disconnect hinders a coherent discussion transitions, which will be necessary to solve problems (environmental, social, economic, health) generated by conventional systems. Our review highlights linkages between transitions nutrition using perspective sustainable explore diversity narratives agro‐food arena, analyze relations systems sustainability, suggest options foster transition toward It is widely acknowledged must entail long‐term its availability, access, utilization, stability dimensions. For deliver for present future generations, all their components need sustainable, resilient, efficient. These intersect at global, national, local, household levels. Different strategies can pursued systems: efficiency increase (e.g., intensification), demand restraint diets), transformation alternative systems). Creating requires moving from an agriculture‐centered policy research framework. This fundamental complex holistic achieve systems, is, turn, prerequisite achieving security.

A new strategic analysis current future P demand/supply concluded that the nation's secondary resources which are produced annually (e.g. livestock manures, sugarcane processing residues) could potentially provide 20% demand by 2050 with further investment recovery technologies. However, much larger legacy stores soil (30 2016 worth over $40 billion 105 more buffer against scarcity or sudden price fluctuations, enable transition input strategies reduce annual surpluses 65%.
