Participatory Research Approaches and Social Dynamics that Influence Agricultural Practices to Improve Child Nutrition in Malawi

The Soils, Food and Healthy Communities project in Malawi uses an interdisciplinary participatory approach to improving child nutrition with resource-poor farmers. The overall research question is: Can legume systems improve soil fertility, food security, and child nutrition? Over 2000 farmers are now experimenting with legume systems in the region. While this article examines the social issues that mitigate the potential success of legume options tested by the farmers, it does not aim at discussing extensively the complex web of interactions between soil fertility, food security, and nutritional status of children. Instead, its focus is on the research process, and more specifically on the social dimensions and participatory approaches, which influenced farmers’ adoption of organic matter technologies and legume options. The Farmer Research Team was critical in mobilizing community interest in changing agricultural practices to improve child health, but faced challenges in village politics and workload. The linkage with child nutrition was a major reason for increased adoption of legumes, and gender relations played a key role in the adoption. A deeper understanding of the limits of participatory approaches helped to develop innovations that may be replicated elsewhere, such as inclusion of grandmothers and a farmer apprenticeship program.     

An aggregation framework to link indicators associated with multifunctional land use to the stakeholder evaluation of policy options

In the last decade efforts have been carried out by the scientific community aimed at building integrated frameworks to support the decision-making process when sustainability issues are addressed. This paper proposes a further advancement in integrated assessment procedures by setting up an operational multi-scale and transparent framework, which comprises the assessment of European regions in terms of sustainability, and the identification of the impact that policy options might have on the sustainability of these regions. The framework is designed for use in ex ante sustainability impact assessment of policy scenarios on multifunctionality of land use and integrates economic, environmental and social issues across a variety of sectors (agriculture, forestry, transport, tourism and energy). The proposed method provides a conceptual framework applicable at different scales (European, regional), and takes into account the great variability of European regions. The described methodology is based on linear additive models to weight and aggregate selected indicators to a set of land use functions identified to describe the goods and services provided by the different land uses that summarise the most relevant economic, environmental and social issues of a region. The framework is designed to allow the evaluation of impacts at an international scale (e.g. the European Union), or on selected regions.The aggregation framework can be used to evaluate the impact that policy options have on the sustainability of multifunctional land use systems with competing demands. A conceptual envelope, called the “trade-off evaluation space”, delineates all possible developments in the functions of the land. The sustainability limits identify the subset of ‘acceptable’ policy options within the trade-off evaluation space, so that the distance of each land use function from sustainability limits can be estimated and trade-offs between the different functions of the multifunctional land use system can be identified. The proposed methodology is adaptable to different contexts: if the assumption is taken that all land use functions are equally weighted the framework can be used to analyse policy cases and take decisions on policy options at the European or regional level. However, at the local-scale the framework can also be applied through a participatory approach and the distribution of weights can be rediscussed with local stakeholders. In both cases the proposed system can be used as a tool for discussion among all interested parties.     

Agricultural diversification as an important strategy for achieving food security in Africa

Farmers in Africa have long adapted to climatic and other risks by diversifying their farming activities. Using a multi‐scale approach, we explore the relationship between farming diversity and food security and the diversification potential of African agriculture and its limits on the household and continental scale. On the household scale, we use agricultural surveys from more than 28,000 households located in 18 African countries. In a next step, we use the relationship between rainfall, rainfall variability, and farming diversity to determine the available diversification options for farmers on the continental scale. On the household scale, we show that households with greater farming diversity are more successful in meeting their consumption needs, but only up to a certain level of diversity per ha cropland and more often if food can be purchased from off‐farm income or income from farm sales. More diverse farming systems can contribute to household food security; however, the relationship is influenced by other factors, for example, the market orientation of a household, livestock ownership, nonagricultural employment opportunities, and available land resources. On the continental scale, the greatest opportunities for diversification of food crops, cash crops, and livestock are located in areas with 500–1,000 mm annual rainfall and 17%–22% rainfall variability. Forty‐three percent of the African cropland lacks these opportunities at present which may hamper the ability of agricultural systems to respond to climate change. While sustainable intensification practices that increase yields have received most attention to date, our study suggests that a shift in the research and policy paradigm toward agricultural diversification options may be necessary.     

In situ conservation of crop genetic resources through maintenance of traditional farming systems

A strategy is suggested for in situ conservation of crop genetic resources whereby conservation efforts are linked to rural development projects in Third World countries. We describe development projects that emphasize preservation of traditional farming systems and succeed in sustaining production by relying on the maintenance of biological and genetic diversity in these systems. Basing agricultural development efforts on indigenous knowledge, technology, and social organization can provide important guidelines for the design of cropping systems that allow lowincome farmers to produce subsistence and cash crops without dependence on external inputs and seed supplies. By incorporating landraces and wild relatives of crops into these cropping systems, major achievements in the conservation of crop genetic resources can be obtained.     

Towards an agroecological assessment of dairy systems: proposal for a set of criteria suited to mountain farming

Ruminant production systems have been facing the sustainability challenge, namely, how to maintain or even increase production while reducing their environmental footprint, and improving social acceptability. One currently discussed option is to encourage farmers to follow agroecological principles, that is, to take advantage of ecological processes to reduce inputs and farm wastes, while preserving natural resources, and using this diversity to increase system resilience. However, these principles need to be made more practical. Here, we present the procedure undertaken for the collaborative construction of an agroecological diagnostic grid for dairy systems with a focus on the mountain farming relying on the use of semi-natural grasslands. This diagnosis will necessarily rely on a multicriteria evaluation as agroecology is based on a series of complementary principles. It requires defining a set of criteria, based on practices to be recommended, that should be complied with to ensure agroecological production. We present how such agroecological criteria were identified and organized to form the architecture of an evaluation model. As a basis for this work, we used five agroecological principles already proposed for animal production systems. A group of five experts of mountain production systems and of their multicriteria evaluation was selected, with a second round of consultation with five additional experts. They first split up each principle into three to four generic sub-principles. For each principle, they listed three to eight categories of state variables on which the fulfilment of the principle should have a positive impact (e.g. main health disorders for the integrated health management principle). State variables are specific for a given production, for example, dairy farms. Crossing principles with state variables enabled experts to build five matrices, with 75 cells relevant for dairy systems. In each cell, criteria are specific to the local context, for example, mountain dairy systems in this study. Finally, we discuss the opportunities offered by our methodology, and the steps remaining for the construction of the evaluation model.     

Steering vaccinomics innovations with anticipatory governance and participatory foresight

Vaccinomics is the convergence of vaccinology and population-based omics sciences. The success of knowledge-based innovations such as vaccinomics is not only contingent on access to new biotechnologies. It also requires new ways of governance of science, knowledge production, and management. This article presents a conceptual analysis of the anticipatory and adaptive approaches that are crucial for the responsible design and sustainable transition of vaccinomics to public health practice. Anticipatory governance is a new approach to manage the uncertainties embedded on an innovation trajectory with participatory foresight, in order to devise governance instruments for collective "steering" of science and technology. As a contrast to hitherto narrowly framed "downstream impact assessments" for emerging technologies, anticipatory governance adopts a broader and interventionist approach that recognizes the social construction of technology design and innovation. It includes in its process explicit mechanisms to understand the factors upstream to the innovation trajectory such as deliberation and cocultivation of the aims, motives, funding, design, and direction of science and technology, both by experts and publics. This upstream shift from a consumer "product uptake" focus to "participatory technology design" on the innovation trajectory is an appropriately radical and necessary departure in the field of technology assessment, especially given that considerable public funds are dedicated to innovations. Recent examples of demands by research funding agencies to anticipate the broad impacts of proposed research--at a very upstream stage at the time of research funding application--suggest that anticipatory governance with foresight may be one way how postgenomics scientific practice might transform in the future toward responsible innovation. Moreover, the present context of knowledge production in vaccinomics is such that policy making for vaccines of the 21st century is occurring in the face of uncertainties where the "facts are uncertain, values in dispute, stakes high and decisions urgent and where no single one of these dimensions can be managed in isolation from the rest." This article concludes, however, that uncertainty is not an accident of the scientific method, but its very substance. Anticipatory governance with participatory foresight offers a mechanism to respond to such inherent sociotechnical uncertainties in the emerging field of vaccinomics by making the coproduction of scientific knowledge by technology and the social systems explicit. Ultimately, this serves to integrate scientific and social knowledge thereby steering innovations to coproduce results and outputs that are socially robust and context sensitive.     

Evaluating Environmental Performance of Pulp and Paper Manufacturing Using the Analytic Hierarchy Process and Life-Cycle Assessment

This article addresses the need for a structured and compre-hensive methodology for assessing the environmental perfor-mance of manufacturing processes. The analytic hierarchy pro-cess (AHP) is used as the basic framework for analyzing environmental impacts and improvement options following a streamlined life-cycle assessment (LCA) approach that is fo-cused on the manufacturing operation. The multicriteria de-cision analysis approach of the AHP is consistent with the LCA concept because the environmental factors can be hierarchi-cally structured into impacts and improvement options. Its po-tential as a valuation tool for impact and improvement assess-ment addresses both qualitative and quantitative issues in environmental decision making.
Through application to a pulp and paper manufacturing case study, the viability of the AHP for evaluating environmen-tal impacts and prioritizing process improvement options rela-tive to these impacts is demonstrated. AHP was used to pro-vide a quantitative tool for the design of a set of weighting factors for impact and improvement analyses.

Pest-Suppression Potential of Midwestern Landscapes under Contrasting Bioenergy Scenarios

Biomass crops grown on marginal soils are expected to fuel an emerging bioenergy industry in the United States. Bioenergy crop choice and position in the landscape could have important impacts on a range of ecosystem services, including natural pest-suppression (biocontrol services) provided by predatory arthropods. In this study we use predation rates of three sentinel crop pests to develop a biocontrol index (BCI) summarizing pest-suppression potential in corn and perennial grass-based bioenergy crops in southern Wisconsin, lower Michigan, and northern Illinois. We show that BCI is higher in perennial grasslands than in corn, and increases with the amount of perennial grassland in the surrounding landscape. We develop an empirical model for predicting BCI from information on energy crop and landscape characteristics, and use the model in a qualitative assessment of changes in biocontrol services for annual croplands on prime agricultural soils under two contrasting bioenergy scenarios. Our analysis suggests that the expansion of annual energy crops onto 1.2 million ha of existing perennial grasslands on marginal soils could reduce BCI between -10 and -64% for nearly half of the annual cropland in the region. In contrast, replacement of the 1.1 million ha of existing annual crops on marginal land with perennial energy crops could increase BCI by 13 to 205% on over half of the annual cropland in the region. Through comparisons with other independent studies, we find that our biocontrol index is negatively related to insecticide use across the Midwest, suggesting that strategically positioned, perennial bioenergy crops could reduce insect damage and insecticide use on neighboring food and forage crops. We suggest that properly validated environmental indices can be used in decision support systems to facilitate integrated assessments of the environmental and economic impacts of different bioenergy policies.     

Resource Conflicts: Challenges to Fisheries Management at the São Francisco River,Brazil

The paper describes factors influencing artisanal fisheries at the São Francisco River in Brazil as an example of the challenges of managing socially and economically valued common-pool resource systems. A rapid assessment of problems affecting São Francisco River fisheries in 10 communities was carried out in 2003, representing the upper, middle, and lower river portions. Field visits, interviews, focus group discussions and a literature survey allowed us to map socioeconomic and environmental factors important to the fisheries, including conflicts and tensions between stakeholders. Federal, state, and municipal governments, industries, farmers, hydroelectric companies, and urban and rural populations all have a stake in river use. Traditional fishers are the most disadvantaged of these stakeholders. With declining fish populations, most of the fishing communities surveyed are now poor, socially excluded, and with few alternative livelihood options. The stakeholders involved in access and use conflicts are artisanal fishers, professional fishers, sport fishers, farmers, enforcement and regulatory agencies, and hydroelectric companies. Traditional fishers have close ties to the river and its environment and they are usually not invited to contribute to resource management decisions. We recommend changes to management structures involving the fishing communities that are essential to resolve the major conflicts and to improve equity and sustainability of artisanal fisheries.     

The environmental impacts of operating an Antarctic research station

We present a life cycle assessment (LCA) of the operation of Casey Station in Antarctica. The LCA included quantifying material and energy flows, modeling of elementary flows, and subsequent environmental impacts. Environmental impacts were dominated by emissions associated with freight operations and electricity cogeneration. A participatory design approach was used to identify options to reduce environmental impacts, which included improving freight efficiency, reducing the temperature setpoint of the living quarters, and installing alternative energy systems. These options were then assessed using LCA, and have the potential to reduce environmental impacts by between 2% and 19.1%, depending on the environmental indicator.     

Integrating farmers’ knowledge on toxic plants and grassland management: a case study on Colchicum autumnale in Austria

High densities of Colchicum autumnale may endanger grassland management in Austria. As the toxic components persist in hay and silage, the continuation of the management of these grasslands, which are often characterised by a high biodiversity, is uncertain. Farmers possess valuable and context-specific know-how on toxic plants and grassland management. This study aims at assessing the contribution of farmers’ knowledge to nature conservation research on toxic plants in grasslands. In total, we conducted 170 face-to-face interviews with farmers managing grasslands with C. autumnale in four areas of Lower Austria. In addition, the farmers were invited to regional workshops to discuss C. autumnale, control measures and related problems. We also encouraged farmers to carry out on-farm experiments. To provide triangulation of the participatory with academic research results, C. autumnale was mapped in three municipalities, covering in total 686 ha. The majority of all grassland plots were extensively managed meadows. More than half of them were not fertilised and were subject to nature conservation regulations. Farmers reported an increase of C. autumnale on 44% of all grassland plots. Of these, grassland management has been extensified in 64%. About 27% of all farmers regarded C. autumnale as a problem. Among farmers who sold hay, 48% considered it as problematic. The field survey showed that C. autumnale covers up to 73% of grasslands. Farmers’ knowledge is an important contribution to nature conservation research and should be included in the design and implementation of agri-environmental schemes so that long-term extensive grassland management can be assured.     

Biodiversity, evolution and adaptation of cultivated crops

The human diet depends on very few crops. Current diversity in these crops is the result of a long interaction between farmers and cultivated plants, and their environment. Man largely shaped crop biodiversity from the domestication period 12,000 B.P. to the development of improved varieties during the last century. We illustrate this process through a detailed analysis of the domestication and early diffusion of maize. In smallholder agricultural systems, farmers still have a major impact on crop diversity today. We review several examples of the major impact of man on current diversity. Finally, biodiversity is considered to be an asset for adaptation to current environmental changes. We describe the evolution of pearl millet in West Africa, where average rainfall has decreased over the last forty years. Diversity in cultivated varieties has certainly helped this crop to adapt to climate variation.     

Exploring the potential of participatory systems thinking techniques in progressing SLCA

Purpose

There are a range of systems thinking-based methods well established for participatory actions that allow for greater integration of various mental models and understanding of systems that should be considered in advancing engagement methods in SLCA. This paper highlights the potential application of participatory modelling approaches based in systems thinking theory as a potential entry point in stakeholder inclusion and understanding impact pathways and system behaviour in social life cycle assessment (SLCA).

Methods

We discuss the application of various systems thinking methodologies to SLCA, along with pertinent examples from literature, and develop a framework that integrates both methodologies.

Results and discussion

Here we propose three distinct benefits of group modelling approaches; (1) procedural benefits through the ability to be inclusive of mental models, various perspectives and enhance stakeholder conceptualisation of a system; and the ability to combine both (2) qualitative and (3) quantitative analysis techniques under a cohesive framework. We propose the specific merits of combining the use of agent-based (AB) and system dynamic (SD) modelling in SLCA due to the emphasis upon consumer decisions and behaviour and the inherently dynamic non-linear cause-effect chains that are common in social systems.

Conclusions

We conclude that many facets of participatory modelling techniques can align with SLCA across the methodology, particularly if enhanced consideration of stakeholders and their various values is desired. We recommend the further development and inclusion of participatory systems thinking-based frameworks to advance the SLCA methodology with specific reference to the ability to enhance interpretation through the analysis of feedbacks that may not be addressed in current approaches.

     

Participatory Resource Monitoring as a Means for Promoting Social Change in Yunnan,China

Recent international forest policies stimulate involvement of communities in forest management as a strategy to improve biodiversity conservation and the quality of local livelihoods. Increasingly, the role of local people in monitoring forest resources is also acknowledged. This paper presents a participatory resources monitoring (PRM) system developed and implemented by representatives of 12 villages, six each within and adjacent to two nature reserves in Yunnan, China. The short-term objectives are to monitor resource and wildlife abundance, resource use, wildlife damage to crops, and land use. Main methods used by the village monitoring team are: (1) observation through forest walk, (2) village interview, and (3) market survey. Monitoring is implemented throughout the year to fit in the daily work of villagers. Staff from the nature reserve or forestry bureau provide support by visiting the villages several days per year. Results indicate that participatory monitoring is a valuable tool for villagers to engage in self-owned management actions. We discuss how monitoring is also a process which could lead to social change. Based on narratives we suggest that participatory monitoring builds trust between stakeholders, changes perceptions and attitudes and leads to more democratic and transparent decision-making. In discussing accuracy, we argue that all stakeholders perceive and interpret nature differently based on different worldviews, knowledge systems, values and beliefs. We argue that if participatory monitoring is to be sustainable, community-based monitoring – preferably linked to scientific monitoring and patrolling – should be designed as a discursive institution where the process of building social capital and inter-actor learning is extremely important. Finally, we briefly reflect upon efforts to scale up participatory monitoring.     

Making the best of both worlds: Can high-resolution agricultural administrative data support the assessment of High Nature Value farmlands across Europe?

Worldwide, the role of farmlands for biodiversity conservation and the delivery of multiple ecosystem services has been widely acknowledged. In the European Union (EU), societal demands to include environmental conservation concerns within the Common Agricultural Policy (CAP) have resulted in the recognition of the importance of maintaining High Nature Value farmlands (HNVf).HNVf constitute complex social-ecological systems, which owe their nature conservation value to the maintenance of specific, mostly low-intensity farming systems, supporting high levels of species and habitats dependent on agricultural practices. Even though HNVf assessment in space and time is essential to evaluate the effectiveness of Rural Development Programmes, the diversity of rural landscapes across EU, the scarcity of data on farming systems, and the lack of common methodological guidelines has hampered the implementation of HNVf mapping and monitoring across Europe. Thus, there is a pressing need to develop and test methodological approaches that may support HNVf assessment across the EU.The Integrated Administration and Control System (IACS) which is mandatory for all EU Member States constitutes a system for the management and control of CAP payments to farmers. Essentially, IACS comprises high-resolution, spatially explicit information on the type and intensity of agricultural land-use. Even though such data exhibits high thematic, spatial and temporal resolution, IACS has seldom been used, due to significant access restrictions. Here, the potential to use IACS data to support the assessment of HNVf was evaluated within the German Federal State of Lower Saxony by implementing a recently developed methodological framework. Sets of indicators known to be essential for identifying potential HNVf and underlying farming systems (expressing landscape structure and composition, farming systems, and crop diversity), were derived from IACS. Spatial patterns of indicators were analyzed at two different scales to delineate the potential distribution of HNVf across Lower Saxony.Results highlighted that most regions in Lower Saxony were characterized by intensive farming practices including high livestock density, high share of intensive crops and low density of linear elements. Only 3% of the Utilized Agricultural Area (UAA) of Lower Saxony potentially constituted HNVf, with the majority of HNVf coinciding with mosaics of arable and/or permanent crops and semi-natural features under less intensive farming practices. Semi-natural grasslands, partially under agri-environment scheme management contracts, covered roughly 1% of the UAA and were mostly intermingled with other farmland habitats in extensively managed agricultural landscapes.In the context of the EU-wide HNVf assessment, IACS constitutes an important source of data, characterized by a high spatial, thematic and temporal resolution of data collected annually. Whilst having the potential for use in HNVf assessment, some challenges remain, especially due to significant access restrictions. Nevertheless, IACS constitutes a powerful tool to evaluate the extent and condition of HNVf across the EU countryside. Making use of IACS data in such a way could provide a stepping-stone towards achieving a more effective balance between the management and control of CAP support payments and the growing societal demands related to the maintenance and enhancement of farmland biodiversity and ecosystem services.     

A conceptual framework and experimental design for analysing the relationship between biodiversity and ecosystem functioning (BEF) in agroforestry systems

There is compelling evidence for positive effects of plant diversity on the functioning of forests and agroecosystems. This information is increasingly used to optimize production systems that provide a wide range of ecosystem services. While agroforestry is actively promoted for the sustainable intensification of agriculture and restoration of degraded landscapes, there is a paucity of knowledge on Biodiversity Ecosystem Functioning (BEF) relationships in agroforestry systems. Since BEF-relationships in agroforestry might be shaped by combinations of different life-forms (e.g. trees, shrubs, herbs) and their interactions, experiences from grassland and forest experiments cannot be readily transferred to agroforestry. This highlights the need for a new type of experiments in agroforestry to advance our understanding of the role of biodiversity for the functioning of these systems. Therefore, our aim was to develop a conceptual framework for analysing BEF-relationships in agroforestry systems and to present an exemplary design for this purpose, which we placed in a (sub)tropical context. Based on designs used in tree diversity experiments, we suggest four major design principles: 1) a trait-based approach for selecting tree and crop species, 2) the integration of trees and crops along a gradient of functional diversity, 3) maintaining constant density across different combinations of life-forms in agroforests through the concept of “growing-patch-density”, and 4) disentangling a priori the effects of species diversity on ecosystem functioning from those of structural and functional diversity, defined here as the variation in structural attributes such as plant dimensions and in plant functional traits, respectively. Our conceptual design and the embedded principles offer a promising avenue to identify important drivers of specific BEF-relationships and to quantify management influences on these. This design can support new research projects that aim at improving ecosystem functioning of agroforestry with the view of optimizing the provision of ecosystem services and facilitation of ecosystem restoration.     

Short-Rotation Coppice of Willow for Phytoremediation of a Metal-Contaminated Agricultural Area: A Sustainability Assessment

Large areas of land contaminated with cadmium (Cd), lead (Pb), and zinc (Zn) are currently in agricultural production in the Campine region in Belgium. Cadmium contents in food and fodder crops frequently exceed legal threshold values, resulting in crop confiscation. This imposes a burden on agriculture and regional policy and, therefore, encourages proper soil management. One way to increase agricultural income and improve soil quality is by growing alternative nonfood crops such as willows in short-rotation coppice (SRC) systems that remediate the soil. This paper compares SRC of willow with rapeseed and energy maize regarding four attributes: metal accumulation capacity, gross agricultural income per hectare, CO₂ emission avoidance potential, and agricultural acceptance. Based on multicriteria decision analysis, we conclude that, although SRC of willow has a high potential as an energy and remediating crop, it is unlikely to be implemented on the short term in Flanders unless the economic incentives for the farmers are improved.     

Co-existence of agricultural production systems

Strategies and best practices for the co-existence of GM and non-GM crops need to be developed and implemented with the participation of farmers and other stakeholders. According to the principle of 'subsidiarity', decisions should be made by the lowest authority possible. When applying this concept to the case of GM crops, the affected society should determine their use and management in a regional decision-making process. Public participation is better accomplished at a lower level, and democratic deficits in decision-making on GMOs are better resolved, enabling farmers to manage or avoid GM crops. Ultimately, voluntary GMO-free zones might be a tool for sustainable co-existence and GM-free production and GMO-free zones might create a specific image for marketing regional products and services, such as tourism.
