    From Lab to Field: Role of Humic Substances Under Open-Field and Greenhouse Conditions as Biostimulant and Biocontrol Agent
    Jindo, Keiji ; Olivares, Fábio Lopes ; Paixão Malcher, Deyse Jacqueline da; Sánchez-Monedero, Miguel Angel ; Kempenaar, Corné ; Canellas, Luciano Pasqualoto - \ 2020

    circular economy - fertigation - foliar application - fulvic acid - humic acid - sustainable agriculture

    The demand for biostimulants has been growing at an annual rate of 10 and 12.4% in Europe and Northern America, respectively. The beneficial effects of humic substances (HS) as biostimulants of plant growth have been well-known since the 1980s, and they can be supportive to a circular economy if they are extracted from different renewable resources of organic matter including harvest residues, wastewater, sewage sludge, and manure. This paper presents an overview of the scientific outputs on application methods of HS in different conditions. Firstly, the functionality of HS in the primary and secondary metabolism under stressed and non-stressed cropping conditions is discussed along with crop protection against pathogens. Secondly, the advantages and limitations of five different types of HS application under open-fields and greenhouse conditions are described. Key factors, such as the chemical structure of HS, application method, optimal rate, and field circumstances, play a crucial role in enhancing plant growth by HS treatment as a biostimulant. If we can get a better grip on these factors, HS has the potential to become a part of circular agriculture.

    Manure Management Practices and Policies in Sub-Saharan Africa: Implications on Manure Quality as a Fertilizer

    greenhouse gas emissions - manure management - policies - practices - Sub-Saharan Africa - sustainable agriculture

    Manure has been used as a fertilizer since ancient times and if well-managed it can be an asset, promoting sustainable agriculture, and increasing crop production, particularly for smallholder farmers in sub-Saharan Africa (SSA). However, most farmers in SSA do not apply recommended manure management practices, such as roofing animal housing, having a water-proof floor or covering manure during storage, causing large nutrient losses during manure storage, increasing greenhouse gas emissions, and reducing the quality of the manure as a fertilizer. This paper compares manure management practices in representative SSA countries, and summarizes government policies and socio-cultural practices that influence the adoption of good (recommended) manure management practices. Three steps were applied in this analysis: (i) review of manure management practices from various literature sources, (ii) interviews on manure management practices and policies with key stakeholders from 13 SSA countries, and (iii) surveys of manure management practices on small, medium, and large scale farms in Ethiopia and Malawi. The review confirms the potential of manure to improve crop yields and promote sustainable agriculture in SSA. Unfortunately, most SSA countries (a) do not explicitly mention manure management in their policies (b) have different ministries that share responsibilities on manure management, often leading to incoherent policies and abnegation of these responsibilities (c) take limited action to promote good practices or enforce legislation on manure management. Also, the field survey indicated that farmers lack knowledge on manure management. However, farmers are able to access agricultural extension services from both government and non-government agencies, although these extension services rarely included information on improved manure management practices. Extension services that encourage exchange and interaction between farmers were most successful in increasing adoption of good manure management practices, and are recommended. In addition, efforts to improve manure management in SSA should strengthen the enforcement of existing policies and provide an enabling environment for adoption of good manure management practices.

    Food justice - global justice - right to food - sustainable agriculture - sustainable consumption
    The concept of food sovereignty is becoming an element of everyday parlance in development politics and food justice advocacy. Yet to successfully achieve food sovereignty, the demands within this movement have to be compatible with the way people are pursuing consumer sovereignty and vice versa. The aim of this article is to examine the different sets of demands that the two ideals of sovereignty bring about, analyze in how far these different demands can stand in constructive relations with each other, and explain why consumers have to adjust their food choices to seasonal production variability to promote food sovereignty and so secure future autonomy.

    This report explores in what way greening and enhancing sustainability of agriculture could be best supported within the CAP: by greening of direct payments (1 st pillar) or by contracts for agri-environmental management (2 nd pillar). Additionally it is explored for which goals it would be meaningful to implement a collective approach for agri-environmental management, next to the current objectives of the support of internationally protected species. The most relevant issues in the Netherlands concerning the sustainable management of natural resources, climate change and biodiversity are the point of departure of the analysis. For a couple of issues it is analysed which objectives can be best reached with which measures and instruments within the CAP.

    Dairy in Europe has undergone many changes in the last few years—the abolition of milk production quotas being a fundamental one. This study explores these changes in relation to the sustained social and environmental viability of the sector and how dairy processors' sustainability programs are a part of that.

    Regime change as outlined in transition theory enhanced through a sociological approach on actors informed this research. More specifically, the notion of obligatory passage points was used to explore the mechanisms through which dominant actors make certain actions mandatory and reify their status as indispensable. The thesis consists of three case studies: the dairy sectors in the Netherlands, Ireland and the United Kingdom. The cases trace the evolution of all sectors since the post-war era, outlining the dominant logic that has guided its development. The sustainability programs of three dairy processors—located in each of the case countries—are also part of the analysis. Data was collected through document analysis and semi-structured interviews.

    The analysis shows that the post-war logic based on the increase of scale and intensification of dairying has continued to shape the development of the sector through today. While the visible impacts of intensive dairy have led to adaptations to the dominant rules and practices, these changes have not been fundamental in nature. The analysis of dairy processors and their sustainability programs revealed that these programs can be an additional tool for compliance to legal standards and the alleviation of pressing societal concerns. However, processors address social and environmentally relevant dairy-related challenges when an effective link to profit can be established. These programs have been unable to ensure that the dairy sector operates within established environmental limits and societal expectations, while providing a stable livelihood for farmers.

    This research contributes to the understanding of sustainability (agri-food) transitions by identifying the mechanisms through which the regime adapts to the shifting environment and dominant actors strive for their own continuity. It also adds to the debate about the role that incumbent actors can have in sustainability transitions—their involvement is important but they are unable to guide such processes. This study advances the empirical ground in sustainability transition studies by focusing on systems in which change is less likely to be technologically driven and where social change plays a larger role. Finally, this thesis connects past development, current challenges, and present engagement in a discussion about the future development of the dairy sector; this adds to the further conceptualization of the complexity and co-evolutionary nature of sustainability transitions.

    Current environmental, economic and social challenges urge agriculture to change to more sustainable modes of production. Insight in the impact of a system or a potential innovation on sustainability could support decision makers in identifying actions towards sustainable development. Over the past decade, therefore, a large number of tools have been developed to assess sustainability performance at farm level. Several concerns, however, have been raised whether assessment results provide reliable and valid conclusions about the sustainability performance of farms, and whether these conclusions can be implemented in practice. To evaluate the contribution of farm-level assessment tools to sustainable development of agriculture, this thesis analyzed current approaches to assessing sustainability. One of these approaches is the sustainability assessment tool RISE 2.0, which was used to assess the sustainability performance of 37 organic farms in Denmark. Analysis of the assessment results showed the impact of decisions, made during the development of a tool (e.g. selection of themes, indicators, reference values, scoring and aggregation method), on the assessment results. This emphasizes the importance of transparency in sustainability assessment tools to understand assessment results and identify actions to improve. Subsequently, a comparison of sustainability assessment tools in practice was made to gain insight into practical requirements, procedures and relevance perceived by farmers. Of 48 indicator-based sustainability assessment tools, only four tools (RISE, SAFA, PG and IDEA) complied to the selection criteria and were applied to assess the sustainability performance of five Danish farms. Characteristics including data requirements, assessment time, complexity, transparency and output accuracy varied between tools. Critical factors in farmers’ perception of tool relevance were context specificity, user-friendliness, complexity of the tool, language use, and a match between value judgements of tool developers and farmers. Farmers, moreover, indicated that implementing conclusions derived from sustainability assessments is challenging given the complex organization of agricultural systems. A more in-depth analysis of the four tools revealed a high diversity in selected indicators, themes, reference values, and scoring and aggregation methods. This results in different conclusions on the sustainability performance of farms, which does not only cause confusion but also affects the trust in, and reliability and implementation of, sustainability assessments. Variability in tools is caused by different perspectives on how to assess sustainability and is related to differences in context, priorities and value judgements of tool developers. These differences also play a role in the prioritization of criteria for indicator selection. To explore whether sustainability experts agreed on which criteria are most important in the selection of indicators and indicators sets for sustainability assessments, two ranking surveys were carried out. Both surveys showed a lack of consensus amongst experts about how best to measure agricultural sustainability. This thesis revealed variability in approaches to assess sustainability at farm level. This makes current assessment tools less suitable for functions that require a high reliability and validity, such as certification. Instead, current assessment tools present a useful starting point for discussion, reflection and learning on sustainable development of farming. To enhance the contribution of tools towards sustainable development of agriculture, more attention should be paid to increasing reliability and validity of tools, and improving transparency, harmonization, participation and implementation of assessments.

    Grasslands play a significant role in the global ecosystem, livestock production and millions of household livelihoods. However, grassland degradation has become a worldwide problem, and rural poverty has become exacerbated in some pastoral areas. The sustainable management and use of grasslands that maintain the productive and adaptive capacity of ecosystems while providing for the well-being of human communities are crucial concerns. In practice, various policy interventions have been initiated by governments all over the world to devote to grassland conservation, livestock production and improving local household livelihoods. This research aims to evaluate the effectiveness of the policy interventions for grassland ecosystems and livestock production in the pastoral areas of China. The conceptual framework for this research is based on Ostrom’s Social-Ecological Systems (SESs) framework. Four specific research questions are addressed. It is hoped that the research findings of this thesis can make a contribution to providing some references for policy development in light of the sustainable management and use of grasslands.

    One of the major challenges facing global society today is the provision of food, water, energy, healthcare and other resources & services in a world characterised by increasing population, mounting environmental stresses and rising inequality. There is a need for circular and resilient food systems which close material flow loops in the entire supply chain from farm ers to consumers and back. This should be done in a resource-efficient manner that includes all relevant actors. This position paper summarises insights by Hans van Meijl, Stijn Reinhard and Ruerd Ruben from Wageningen Economic Research into what has been dubbed the inclusive and sustainable economy. Therefore, five overarching challenges, five scoping issues, and five beneficial economic principles are discussed. In addition, the authors formulate five key insights regarding feasible policy strategies and attempt to contribute to the analysis of leverage points relevant to upscaling and to anchoring market innovations that sustain sustainable and inclusive agri-food systems.

    EU agriculture is currently in transition from conventional crop protection to integrated pest management (IPM). Because biocontrol is a key component of IPM, many European countries recently have intensified their national efforts on biocontrol research and innovation (R&I), although such initiatives are often fragmented. The operational outputs of national efforts would benefit from closer collaboration among stakeholders via transnationally coordinated approaches, as most economically important pests are similar across Europe. This paper proposes a common European framework on biocontrol R&I. It identifies generic R&I bottlenecks and needs as well as priorities for three crop types (arable, vegetable and perennial crops). The existing gap between the market offers of biocontrol solutions and the demand of growers, the lengthy and expensive registration process for biocontrol solutions and their varying effectiveness due to variable climatic conditions and site-specific factors across Europe are key obstacles hindering the development and adoption of biocontrol solutions in Europe. Considering arable, vegetable and perennial crops, a dozen common target pests are identified for each type of crop and ranked by order of importance at European level. Such a ranked list indicates numerous topics on which future joint transnational efforts would be justified.

    The GAES database (Version 01a) is a newly developed Global Agro-Environmental Stratification within the EU SIGMA (Stimulating Innovation for Global Monitoring of Agriculture) project. GAES will serve as a new agro-environmental stratification for better global monitoring of the agricultural production on the basis of Earth Observation data and crop growth models. It is anticipated that GAES will be exploited for a wider range of applications, some within SIGMA, towards data gap analysis that identifies agro-environmental strata with limited capacity and monitoring data on agricultural production. GAES was produced by applying segmentation techniques to newly available global agroenvironmental data with a high spatial resolution re-sampled to 1 km spatial resolution. The datasets were able to stratify the agricultural production zones according to the region’s agro-environmental characteristics, including climatic regimes, soil, terrain, elevation conditions, water availability and land cover proprieties. The GAES strata obtained by segmentation at four different spatial levels (with Level 4 as the most detailed) have been further characterised and described in terms of phenology (e.g. start and peak of the growing season), agricultural (water) management practices, field size, biotic constraints, national and sub-national crop production statistics, GDP, transport infrastructure conditions or market accessibility. The GAES database has four hierarchical layers, with 92 attributes. GAES Level 1 has 194 agro-environmental (AE) types (818 strata); GAES Level 2 has 300 AE types (1,688 strata); GAES Level 3 has 374 AE types (2,087 strata); GAES Level 4 has 516 AE types (3,208 strata). GAES typology is a combination of temperature, altitude, parent material and land cover characteristics. GAES Version 01 has become freely available.

    The project Sustainable rose cultivation aimed to achieve a sustainable and energy efficient rose cultivation by a controlled use of assimilation lighting, an optimum use of the cooling and an integrated control strategy for mildew. The production came to 320 stems.m-2 average weight 54 grams. The branch length and bud size varied through the season. There was no saving on electricity. There was a significant saving on heat. The improvement of the energy efficiency was totally determined by the reduction of the heat consumption. The light utilization efficiency was 2:44 g.mol-¹ and increased compared to the previous year. Cooling and forced ventilation had a positive effect on the stem elongation in the autumn. The installation with forced ventilation from above combined with the screen had a favourable effect on the climate, especially in the humidity control under a largely (95-98%) closed screen. The payback period of the investment in airconditioning is within 3 years.

    Decision-makers increasingly use life-cycle assessment (LCA) as a tool to measure the environmental sustainability of products. LCA is of particular importance in globalized agricultural supply chains, which have environmental effects in multiple and spatially dispersed locations. Incorporation of impacts on biodiversity that arise from agricultural production systems into environmental assessment methods is an emerging area of work in LCA, and current approaches have limitations, including the need for (i) improved assessment of impacts to biodiversity associated with agricultural production, (ii) inclusion of new biodiversity indicators (e.g. conservation value, functional diversity, ecosystem services) and (iii) inclusion of previously unaccounted modelling variables that go beyond land-use impacts (e.g. climate change, water and soil quality). Synthesis and applications. Ecological models and understanding can contribute to address the limitations of current life-cycle assessment (LCA) methods in agricultural production systems and to make them more ecologically relevant. This will be necessary to ensure that biodiversity is not neglected in decision-making that relies on LCA.
