  • Exploring solution spaces for nutrition-sensitive agriculture in Kenya and
           Vietnam
    • Abstract: Publication date: April 2020Source: Agricultural Systems, Volume 180Author(s): Carl Timler, Stéphanie Alvarez, Fabrice DeClerck, Roseline Remans, Jessica Raneri, Natalia Estrada Carmona, Nester Mashingaidze, Shantonu Abe Chatterjee, Tsai Wei Chiang, Celine Termote, Ray-Yu Yang, Katrien Descheemaeker, Inge D. Brouwer, Gina Kennedy, Pablo A. Tittonell, Jeroen C.J. GrootAbstractSmallholder agriculture is an important source of livelihoods in South Asia and sub-Saharan Africa. In these regions the highest concentrations of nutritionally vulnerable populations are found. Agricultural development needs to be nutrition-sensitive, and contribute simultaneously to improving household nutrition, farm productivity and environmental performance. We explored the windows of opportunities for farm development and the potential of crop diversification options for meeting household dietary requirements, whilst concurrently improving household economic performance in contrasting smallholder farm systems in Kenya and Vietnam. Farm and household features and farmer perspectives and priorities were integrated into a farm-household model that allowed quantification of a diverse set of nutritional, labour and productive indicators. Using a multi-objective optimization algorithm, we generated ‘solution spaces’ comprising crop compositions and management configurations that would satisfy household dietary needs and allowed income gains. Results indicated site-specific synergies between income and nutritional system yield for vitamin A. Diversification with novel vegetables could cover vitamin A requirements of 10 to 31 extra people per hectare and lead to greater income (25 to 185% increase) for some households, but reduced leisure time. Although the Vietnamese sites exhibited greater nutrient system yields than those in Kenya, the household diets in Kenya had greater nutrient adequacy due to the fact that the Vietnamese farmers sold greater proportions of their on-farm produced foods. We conclude that nutrition-sensitive, multi-method approaches have potential to identify solutions to simultaneously improve household income, nutrition and resource management in vulnerable smallholder farming systems.
       
  • Assessing the importance of plant, soil, and management factors affecting
           potential milk production on organic pastures using regression tree
           analysis
    • Abstract: Publication date: April 2020Source: Agricultural Systems, Volume 180Author(s): Chelsea H. Zegler, Mark J. Renz, Geoffrey E. Brink, Matthew D. RuarkAbstractCertified organic dairies are required to utilize pastures for a portion of forage intake. Pasture species composition, management, and soil fertility are known to influence milk production, but have not been studied concurrently. We evaluated agronomic and management variables on 20 organic dairies in the upper midwestern United States to determine factors associated with potential pasture milk production. At each farm, two pastures were sampled just prior to grazing in June and September for species composition, productivity, and forage nutritive value. Soil samples and management information were collected in October. Potential milk production was calculated based on forage productivity, cell wall concentration and digestibility, and estimated dry matter intake by a 500 kg cow. A regression tree prioritized the factors associated with potential milk production. Improved legume cover exceeding 40% in June increased potential milk production by 97%. Non-improved grass cover 75%. Maintaining residual sward height at 9 cm or greater throughout the year was also associated with increased milk production. Soil fertility explained little of the variability in milk production. Our results suggest prioritizing management of residual height and improved legume and non-improved grass cover are critical for high milk production from organic pastures in the Upper Midwest.
       
  • Digitalisation of agricultural knowledge and advice networks: A
           state-of-the-art review
    • Abstract: Publication date: April 2020Source: Agricultural Systems, Volume 180Author(s): Simon Fielke, Bruce Taylor, Emma JakkuAbstractDigitalisation is widely regarded as having the potential to provide productivity and sustainability gains for the agricultural sector. However, there are likely to be broader implications arising from the digitalisation of agricultural innovation systems. Agricultural knowledge and advice networks are important components of agricultural innovation systems that have the potential to be digitally disrupted. In this paper, we review trends within agricultural knowledge and advice networks both internationally and in Australia, to anticipate and prepare for potential transformations in these networks.Through a combined structured and traditional review of relevant literature, we come to three key conclusions regarding the state-of-the-art. First, the connectivity of humans and technologies in agricultural knowledge and advice networks and value chains will likely continue to increase. Second, transparency of agricultural practices and informational interaction between farmers, advisors, agri-businesses, consumers and regulators will drive and be driven by growing connectivity. Finally, there are likely to be challenges balancing the priorities of various agricultural stakeholders as agricultural innovation systems digitalise. These findings have implications for the oversight of international agri-food sectors.
       
  • Adaptation to extreme weather conditions and farm performance in rural
           Pakistan
    • Abstract: Publication date: April 2020Source: Agricultural Systems, Volume 180Author(s): Muhammad Faisal Shahzad, Awudu AbdulaiAbstractExtreme weather conditions resulting from climate change pose a formidable challenge to many farmers worldwide. In this article, we analyze farmers' adaptation to extreme weather conditions using climate-smart farm practices (CSFP), and the impact of adoption of these adaptation strategies on farm performance, using recent farm-level data from three agro-ecological zones of Pakistan. Most of the earlier studies on Pakistan used methods that did not account for unobserved characteristics such as innate skills and risk preferences, resulting in inconsistent estimates. We employ an endogenous switching regression model to account for potential endogeneity and selection bias arising from observable and unobservable factors. The empirical results show that adoption of CSFP contributes to higher farm net returns. The findings further reveal that adoption of these practices significantly reduces volatility of farm net returns and farmers' exposure to downside risk. We also find that access to extension services and education of the household head positively influence the likelihood of adapting CSFP in response to extreme weather conditions.
       
  • Examining the policy-practice gap: The divergence between regulation and
           reality in organic fertiliser allocation in pasture based systems
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Evgenia Micha, William Roberts, Lilian O’ Sullivan, Kay O’ Connell, Karen DalyAbstractSlurry and animal manure generated from livestock production systems are typically recycled back to land to replace nutrients removed in products leaving the farm such as milk, meat and grass. Avoiding environmental losses of nutrients due to slurry spreading requires careful management, contingent on farmers following agronomic advice and policy regulation, yet, nutrient losses to water from agriculture continues to put a significant pressure on water quality. The objective of this study was to examine whether a policy-practice gap in slurry management exists on farms by identifying the factors that influence the decision to spread slurry, across the farm. To achieve this, a Heckman selection model was used to identify the drivers of slurry management using farm and field management records and soil information from commercial livestock farms combined with spatial datasets on landscape position. The main drivers influencing the decision to spread slurry were practical considerations relating to the structure and spatial arrangement of fields on the farm, such as proximity to farm yard, as well as landscape position. Field and landscape variables were also related such as slope, elevation, drainage capacity, soil type, presence of open ditches, and soil phosphorus (P) level. Fields with excessive soil P content had a high probability of receiving slurry in greater amounts, thus challenging the assumption that farmers use soil testing to guide slurry management, and identifying the main agri-environmental policy-practice gap and a need for better knowledge exchange in this area. Despite current policy, practical considerations override soil testing and these results showed that slurry management and allocation is rooted in the spatial arrangement of fields on the farm. The results indicated that farmer decisions are driven by factors that relate to the time, cost and labour involved in spreading slurry, indicating the need for water quality measures and policy to consider the practical constraints and considerations from the viewpoint of the farm.
       
  • Scaling practices within agricultural innovation platforms: Between
           pushing and pulling
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Edmond Totin, Barbara van Mierlo, Laurens KlerkxAbstractGrowing empirical evidence suggests that innovation platforms can be effective in enhancing agricultural research impact by creating an enabling environment for scaling of innovations such as novel technologies, practices and busines models . However, efforts to understand how these innovation platforms operate to scale innovations are insufficient. Such knowledge is critical for improving the design of agricultural innovation systems, specifically within the context of a rising interest in the innovation platform approach to support the transformation of agriculture across Africa. This paper investigates the scaling approaches employed by innovation platforms established in Rwanda. The study focused on four innovation platforms created as part of the Sub-Saharan Africa Challenge Program and analysed their activities and the resulting scaling outcomes. The findings show that two approaches can be effectively combined during the intervention; (1) the innovation process that resembles a traditional, linear approach of finding short-term solutions to specific problems (push approach) and (2) the network building process where platforms employed multi-level, transdisciplinary processes (pull approach). In two areas, the platform activities appeared to have contributed to increased revenues of farmers. The alignment of the innovation platform activities with political agendas or broadly, the extent to which the scaling strategy considers the existing conducive context is shown to play a critical role in the scaling process. The study shows that a balanced combination of both push and pull approaches and a strategic linkage between the platform activities and external development – government policies and interventions – are critical for a productive agricultural transformation in Sub-Saharan Africa. The findings also indicate that the scaling processes require a “protected space” to materialise, and the scaling approach needs flexibility to accommodate the complexity of each innovation.
       
  • Scenario for structural development of livestock production in the Baltic
           littoral countries
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Olli Niskanen, Antti Iho, Leena KalliovirtaAbstractLivestock production in developed countries has undergone profound changes in recent decades and this development seems to continue apace. One consequence is that manure is being — and will be — produced on fewer but larger farms. Data on the bulk of manure nutrients from each country are published by Eurostat, but it is not known how manure is distributed across farms of different sizes. This study 1) puts forward an estimate of the distribution of main manure nutrients between farms of different sizes, 2) estimates how this distribution will change in the near future and 3) discusses the land use effects of this development. Results suggest that by the year 2030 farms housing>500 livestock units will produce more than two-thirds of all manure phosphorus, whereas the proportion in 2010 was one-third. With the Nitrates Directive limiting the use of organic nitrate of manure, growing farms need to acquire, or conclude contracts for the use of, 4.9 million hectares from exiting farms or the open market in order to comply with manure spreading requirements. This shift will involve 64% of the total spreading area of 2010 and 15% of the total utilized agricultural area of the regions studied. In light of these predictions, international nutrient policies should consider the evolution of farm structure in general and manure phosphorus agglomeration in particular. Also salient is improved co-operation beyond the single farm level to ensure the functionality of crop-livestock systems.
       
  • The impact of climate change on agricultural productivity in Romania. A
           country-scale assessment based on the relationship between climatic water
           balance and maize yields in recent decades
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Remus Prăvălie, Igor Sîrodoev, Cristian Patriche, Bogdan Roșca, Adrian Piticar, Georgeta Bandoc, Lucian Sfîcă, Adrian Tişcovschi, Monica Dumitraşcu, Carmen Chifiriuc, Valentina Mănoiu, Ştefan IordacheAbstractThe impact of climate change on agricultural systems has become a reality that currently threatens food security in numerous regions worldwide. However, concrete consequences of climate change on agricultural yields still remain unknown in many countries around the world, including Romania. This study conducts a first-ever analysis of the impact of climate change on maize productivity in Romania, the European Union's leader in maize harvested production, which holds almost 30% of the European maize production. The paper explores complex statistical relationships between the climatic water balance (CWB)/its constituting parameters precipitation (P) and reference evapotranspiration (ETo) and maize yields (Zea mays L.) recorded nationally from 1990 to 2013, a key-period in Romania in terms of climate and socio-political changes. The analysis of various agro-climatic data, based on well-established methods (linear regression and bootstrapping), showed that the countrywide dependence of maize yields variability to changes in the analyzed climatic variables was considerable and reached peak values of roughly 60% for the CWB-yield relationship and around 50% for the P-yield and ETo-yield relationships. At the same time, a significant sensitivity of maize yield dynamics was found in response to a 1-unit climate change, which, on average, was quantified at 5 kg/ha/yr for a 1-mm variation of the CWB, and at 19 kg/ha/yr and 11 kg/ha/yr for a 1-mm change in P and ETo, respectively. In addition to this agricultural impact, our findings regarding the economic impact associated to concrete climatic trends (CWB decreases and ETo increases over the 24 years, consistent with an overall increase of the humidity deficit, and P increases, consistent with humidity surplus) indicate total costs of approximately 53 mil € (or almost 1% of the national agricultural gross domestic product) for the CWB-yield relationship, and of ~200 mil € (~3%) for ETo-yield. It was found that the separate influence of P in maize dynamics was positive, with net financial gains of up to ~130 mil € (~2%). However, our findings show that only the economic costs associated with the impact of ETo on maize productivity are highly statistically reliable. Our results issue a warning about the urgent measures to fight climate change effects on agriculture in Romania, which are necessary especially in the counties located in the Extra-Carpathian regions, highly vulnerable to climate dynamics.
       
  • Negative effects of farmland expansion on multi-species landscape
           connectivity in a tropical region in Southwest China
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Yi An, Shiliang Liu, Yongxiu Sun, Fangning Shi, Shuang ZhaoThe expansion of farmland has negative effects on the natural landscape patterns supporting ecological processes, which in turn can be reflected in changes in the landscape connectivity for animal movements. There is an urgent need to address the issue of the changes to landscape connectivity caused by farmland expansion, especially in tropical areas in Southwest China that have high biodiversity levels and intense human cultivation. Using Menghai County in Xishuangbanna as the study area, six landscape pattern indexes were used to evaluate the landscape patterns and fragmentation based on land use data, and a multi-species circuit theory method was used to quantitatively analyze the changes and spatial variability in landscape connectivity. The results showed that the encroachment of farmland greatly increased the degree of landscape fragmentation. Current density maps of circuit connectivity based on multi-species showed that the spatial differences in the landscape ecological networks were obvious. The key corridors identified by the Zonation model showed that the landscape connectivity in the western area of Menghai County was higher than that in the central area. Comparing the changes between different periods, the maximum current declined the most, with a loss of nearly 25%, from 1995 to 2000. By 2000, the key corridors in the central region had almost completely disappeared. The above information indicated that the farmland expansion led to fragmentation, influenced the movement processes of the regional wild species and reduced the degree of landscape connectivity. This study on the evaluation of the impact of farmland expansion will improve the understanding of the effects of human activities on regional landscape connectivity and provide an operational approach to conservation planning.Graphical abstractUnlabelled Image
       
  • How farmers learn to change their weed management practices: Simple
           changes lead to system redesign in the French West Indies
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Landry Deffontaines, Charles Mottes, Pauline Della Rossa, Magalie Lesueur-Jannoyer, Philippe Cattan, Marianne Le BailAbstractHerbicides used in agriculture pollute water worldwide. However, several weed management alternatives can reduce herbicide applications. The understanding of interactions between agronomics and the learning and social processes that favor changes in practices on a territorial scale is still far from complete. Despite the call for systemic change approaches, most studies are still based on technology transfer. Research and extension services provide references on alternative weed management practices and promote their use among farmers. We surveyed 33 farmers in a 45 km2 tropical catchment plus five institutional extension services. We analyzed changes in weed management practices on the 33 farms belonging to three different agricultural chains: local diversified horticulture, sugarcane, and export banana. For each change, we analyzed the learning processes and the networks involved in information exchanges. First, we show that the complexity of the practices promoted by extension services limits their adoption. Second, we show that simple practices adopted by farmers are part of a slow trajectory of change involving the gradual acquisition of knowledge. A redesign of cropping systems can emerge as the result of a gradual adding of complexity in practices and/or a specific systemic change on a cropping system scale. Sharing knowledge and resources in a non-competitive way speeds up changes among farmers sharing resources and promotes the redesigning of cropping systems. Third, we show that the structure and functioning of relational networks limit changes in practices on a watershed scale. We thus recommend that innovation design should incorporate co-designing of the pathway of change, by designing a succession of simple changes rather than a complex final system only. We recommend including non-competitive resource pooling among farmers in the co-designing of innovation.
       
  • The impact of climate change on farming system selection in Ghana
    • Abstract: Publication date: March 2020Source: Agricultural Systems, Volume 179Author(s): Prince Maxwell EtwireAbstractFarmers are already responding to climate change by adjusting their practices. An important adaptation strategy is the switching of farm types, that is, switching from a vulnerable farming system to one that is more resilient. Using household, farm, and climate data (8700 observations) from Ghana, we estimate a multinomial logit in order to determine the factors that influence the selection of farm types and the implications of those choices. As expected, we find that climate determines the choice of farming system. Based on the multinomial estimates, a simulation of the effects of climate change shows that farmers will likely adapt by switching from environmentally sensitive specialised food-crop and tree-based (plantation) farms to specialised livestock and mixed (food-crop and livestock) farms. All things being equal, a decline in tree-based farms resulting from a climate induced agro-ecological shift (for example, conversion of forest to savannah) or a shortening of the growing season will imply a drop in the aggregate value of agricultural output since plantations are currently the most profitable farm type.
       
  • A bio-economic model for cost analysis of alternative management
           strategies in beef finishing systems
    • Abstract: Publication date: Available online 26 November 2019Source: Agricultural SystemsAuthor(s): C. Kamilaris, R.J. Dewhurst, B. Vosough Ahmadi, P. Crosson, P. AlexanderAbstractGlobal population growth together with rising incomes is increasing the demand for meat-based products. This increases the need to optimize livestock production structures, whilst ensuring viable returns for the farmers. On a global scale, beef producers need tools to assist them to produce more high-quality products whilst maintaining economic efficiency. The Grange Scottish Beef Model (GSBM) was customized to simulate beef finishing enterprises using data from Scottish beef finishing studies, as well as agricultural input and output price datasets. Here we describe the model and its use to determine the cost-effectiveness of alternative current management practices (e.g. forage- and cereal-based finishing) and slaughter ages (i.e. short, medium or long finishing duration). To better understand drivers of profitability in beef finishing systems, several scenarios comparing finishing duration, gender, genetic selection of stock for growth rate or feed efficiency, as well as financial support were tested. There are opportunities for profitable and sustainable beef production in Scotland, for both cereal and forage based systems, particularly when aiming for a younger age profile at slaughtering. By careful choice of finishing systems matched to animal potential, as well as future selection of high performing and feed efficient cattle, beef finishers will be able to enhance performance and increase financial returns.
       
  • Flows in Agro-food Networks (FAN): An agent-based model to simulate local
           agricultural material flows
    • Abstract: Publication date: Available online 25 November 2019Source: Agricultural SystemsAuthor(s): Hugo Fernandez-Mena, Benoit Gaudou, Sylvain Pellerin, Graham K. MacDonald, Thomas NesmeAbstractAgro-food networks are characterized by complex material exchanges among farms, processors, consumers, and waste managers involved in fertilization, food, feed and bioenergy production. Better coordination of material exchanges at the local scale can facilitate more efficient resource use. Here, we present a new agent-based model, “Flows in Agro-food Networks” (FAN), which simulates the processing and exchange of fertilizers, feed, food and wastes among farms and multiple upstream or downstream partners (feed and fertilizer suppliers, food industries, waste processors, and anaerobic digesters) in small farming regions. FAN includes a series of environmental indicators that can be used to assess alternative scenarios in terms of ecosystem services, nutrient cycling, and resource autonomy. We use a French case study to demonstrate FAN’s dynamics and to explore the sensitivity of key parameters. We show a strong influence of spatial distance between agents, their disposition to exchange, and their preference for specific materials on local agro-food network simulations. FAN is powerful theoretical tool to explore and assess opportunities for a circular economy in small farming regions and to unravel interactions between recycling, environmental performance and food production.
       
  • Good intentions, bad extension systems' How the ‘Garden Store
           Approach’ crippled tea expansion in Kigezi sub-region, SW Uganda
    • Abstract: Publication date: Available online 19 November 2019Source: Agricultural SystemsAuthor(s): Ronald Twongyirwe, Rogers Bariyo, Hannington Odongo, Charles Muchunguzi, Prudence Kemigisha, Viola NyakatoAbstractThe Garden Store Approach (GSA) was introduced in the tea sub-subsector in the Kigezi sub-region to establish tea in places where the crop was not traditionally grown. In this approach, the Lead Agency (LA) and Nursery Bed Operators (NBOs) planted and maintained tea gardens for the farmers for the first six months, and later withdrew following payment by the District Local Governments. Young tea gardens were left to farmers, and in most places, the gardens were “choked” by weeds as a corollary of abandonment. To illuminate the nature of the politics and the weed problem in the area – our objectives are two-fold: 1) to profile farmers who planted tea under the GSA in Kigezi sub-region; and 2) to illuminate farmers' reasons for reluctance to control weeds in their tea gardens. We employed mixed methods. A questionnaire was administered to a total of 1208 tea farmers (households) that benefitted from the GSA in 4 districts: Kanungu (n = 466), Kisoro (n = 235), Kabale (n = 353) and Rubanda (n = 154). The households were categorised into 3 (based on the weeding status of their gardens): 1) unweeded, 2) weeded and 3) both weeded and unweeded. Household data were analysed using Principle Components Analysis (PCA) and Cluster Analysis (CA). Our data show that farmers with “sufficient” land sizes, moderate income and household sizes were more likely to participate in the GSA. The main reasons for not controlling weeds were: 1) a lack of finances to control weeds (28% to 65%), 2) the Lead Agency's (LA) failure to fulfil their promise of controlling weeds (7% to 14%), 3) while 4% to 9% highlighted a lack of labour as the main challenge. Issues of market access, large size of tea gardens, poor sense of ownership of the tea gardens, ignorance about tea management were also outstanding. The study shows that well–intended development can be captured by highly placed political actors: the weaknesses and failures in the tea weed management and the poor state of the tea was mostly rooted in the fundamental flaws embedded in the GSA. Although the motivation of tea expansion was well founded, the GSA created large uncertainties. Significant effort is required through a focused extension system, to train farmers on weed management and other agronomic practices. More broadly, extension systems should be organic, specific to farmer needs, and deliberate efforts should be made to divorce technical advice from mere amassing of political capital.
