RAAIS is a diagnostic tool that can guide the analysis of complex agricultural problems and innovation capacity of the agri- cultural system in which the complex agricultural problem is embedded. RAAIS focuses on the integrated analysis of different dimensions of problems (e.g. biophysical, technological, socio-cultural, economic, institutional and political), interactions across different levels (e.g. national, regional, local), and the con- straints and interests of different stakeholder groups (farmers, government, researchers, etc.). Innovation capacity in the agricultural system is studied by analysing (1) constraints within the institutional, sectoral and technological subsystems of the agricultural system, and (2) the existence and performance of the agricultural innovation support system. RAAIS combines multiple qualitative and quantitative methods, and insider (stakeholders) and outsider (researchers) analyses which allow for critical triangulation and validation of the gathered data. Such an analysis can provide specific entry points for innovations to address the complex agricultural problem under study, and generic entry points for innovation related to strength- ening the innovation capacity of agricultural system and the functioning of the agricultural innovation support system. The application of RAAIS to analyse parasitic weed problems in the rice sector, con- ducted in Tanzania and Benin, demonstrates the potential of the diagnostic tool and provides recommendations for its further development and use. © 2014 The Authors.

Introduction The Agricultural Innovation System (AIS) approach has become increasingly popular as a framework to analyse, and explore solu- tions to, complex agricultural problems (e.g. Hall et al., 2003; World Bank, 2006). The AIS approach evolved from a transition from technology-oriented approaches, to more systems-oriented ap- proaches to agricultural innovation (e.g. Klerkx et al., 2012a). Within the AIS approach, innovation is perceived as a process of com- bined technological (e.g. cultivars, fertilizer, agronomic practices) and non-technological (e.g. social practices such as labour organi- zation or institutional settings such as land-tenure arrangements) changes (Hounkonnou et al., 2012; Leeuwis, 2004). Such changes occur across different levels (e.g. field, farm, region), and are shaped by interactions between stakeholders and organisations inside and outside the agricultural sector (Kilelu et al., 2013; Klerkx et al., 2010). Adopting an AIS approach to study complex agricultural prob- lems has important implications for research. First, it requires an analysis that acknowledges and integrates the different dimen- sions, levels and stakeholders’ interests associated with the problem under review. Second, it necessitates a holistic understanding of the innovation capacity of the agricultural system in which the complex problem is embedded (Hall, 2005). Third, it requires insight in the structural conditions provided by the agricultural innovation support system that can enable or constrain innovation in the agricultural * Corresponding author.

Fourth, it re- quires a thorough understanding of the interactions between complex agricultural problems, innovation capacity in the agricul- tural system and the agricultural innovation support system. Despite the recent development and application of a variety of methods that can support AIS analyses (e.g. World Bank, 2012), the potential of the AIS approach to address complex agricultural prob- lems remains underutilized in many fields of study (e.g. Schut et al., 2014a). Four main reasons for this were identified. First, methods used for the analysis of complex agricultural problems generally have a narrow focus, rather than a holistic view. They support the anal- ysis of a specific dimension (e.g. the economic dimension in Beintema et al., 2012), level (e.g. the national level in Temel et al., 2003), or stakeholder group (e.g. farmers in Amankwah et al., 2012; Totin et al., 2012). Second, studies that do include analysis of multiple dimen- sions of problems (e.g. Singh et al., 2009), interactions across different levels (e.g. Douthwaite et al., 2003) or multi-stakeholder dynam- ics (e.g. Hermans et al., 2013) often have limited attention for the integrated analysis of these features of complex agricultural prob- lems. Third, studies that integrate the analysis of multiple dimensions of problems, interactions across different levels andmulti-stakeholder dynamics (e.g. Lundy et al., 2005; van Ittersum et al., 2008) have limited attention for understanding innovation capacity in the ag- ricultural system and the functioning of the agricultural innovation support system. A fourth reason is that the majority of AIS studies are conducted ex-post (e.g. Basu and Leeuwis, 2012), lack a clear structure to delineate system’s boundaries (Klerkx et al., 2012b), or are based on comprehensive studies which take considerable time (e.g. Jiggins, 2012). Although such studies provide a better under- standing of the drivers of innovation in agricultural systems, their diagnostic ability to identify entry points for innovation to over- come complex agricultural problems is limited. Based on the above review of the availability, scope and use of methods for AIS analyses, we have developed and tested a diag- nostic tool that can support the Rapid Appraisal of Agricultural Innovation Systems (RAAIS). RAAIS fits within a tradition of ‘rapid appraisal approaches’ used in the field of agriculture, including the Participatory (Rapid) Rural Appraisal (Chambers, 1994), Rapid Ap- praisal of Agricultural Knowledge Systems (RAAKS: Engel, 1995) and the Rapid Appraisal of Potato Innovation Systems (Ortiz et al., 2013). RAAIS integrates and builds upon existing (agricultural) innova- tion system concepts and combines multiple methods of data collection. The objectives of RAAIS are to provide a coherent set of (1) specific entry points for innovation to address complex agri- cultural problems, and (2) generic entry points that can enhance innovation capacity of the agricultural system and the perfor- mance of the agricultural innovation support system. The aim of this paper is to provide a conceptual framework (Section 2) and a methodological framework (Section 3) for RAAIS. Based on its ap- plication in a study on parasitic weeds in rice production in Tanzania and Benin, we reflect on the extent to which RAAIS is able to meet its objectives, and provide recommendations for further develop- ment and use of RAAIS (Section 4), followed by themain conclusions (Section 5). 2. Conceptual framework for RAAIS The agricultural innovation system – including both the agri- cultural system and its innovation capacity and the agricultural innovation support system – may be very good at tackling some complex agricultural problems, but may be incapable to deal with others (Hung and Whittington, 2011; Markard and Truffer, 2008). It underlines that understanding complex agricultural problems, in- novation capacity in the agricultural system, and the functioning of the agricultural innovation support system requires integrative analysis. Despite of their interrelated character, we deem it useful for analytical purposes to first address them separately (Sections 2.1, 2.2 and 2.3), before showing their embeddedness (Section 2.4). 2.1. Complex agricultural problems Complex agricultural problems are defined as problems (1) that have multiple dimensions (Schut et al., 2014b), (2) that are em- bedded in interactions across different levels (Giller et al., 2008), and (3) where a multiplicity of actors and stakeholders are in- volved (Funtowicz and Ravetz, 1993). Regarding the first, complex agricultural problems are an interplay of biophysical, technologi- cal, social-cultural, economic, institutional and political dimensions. To exemplify this, we use a case by Sims et al. (2012), who analyse constraints for the upscaling of conservation agriculture in sub- Saharan Africa. They demonstrate how import taxes on steel, but not on imported agricultural machinery (institutional dimension), disadvantage manufacturers in developing locally adapted agricul- tural equipment such as no till planters (technological dimension) for effective soil conservation for sustainable cropmanagement (bio- physical dimension). Concerning the second, the dimensions of complex agricultural problems often have different implications across different levels. Mitigating the impact of agro-industrial biofuel production on food security, for instance, will require different strat- egies when approached at the national level (e.g. policies avoiding agro-industrial biofuel production in regions where pressure on ag- ricultural land is already high) or at the farm household level (e.g. balancing the allocation of household labour to on-farm crop pro- duction and off-farm plantation work) (Schut and Florin, under review). Nevertheless, the different levels are interrelated, and consequently, coherent multi-level strategies are required. Regard- ing the third, complex agricultural problems are characterised by the involvement of a multitude of actors, stakeholders and the organisations they represent (Hounkonnou et al., 2012; Ortiz et al., 2013) (Table 1). Actors include about anyone that can be related di- rectly or indirectly to a problem, or the potential solution. Stakeholders are those actors or actor groups with a vested inter- est in addressing the problem (McNie, 2007) and their participation in exploring solutions to complex agricultural problems is per- ceived as a critical success factor (e.g. Giller et al., 2011). Stakeholder participation can provide enhanced insights in the different dimen- sions of the problem, and the types of solutions that are both technically feasible, and socio-culturally and economically acceptable (Faysse, 2006). However, stakeholder groups are no ho- mogeneous entities and often focus on their own, rather than a common, interest (Leeuwis, 2000).

Schut et al./Agricultural Systems 132 (2015) 1–11 2.2. Innovation capacity in the agricultural system The agricultural system is defined as the “operational unit of ag- riculture” including all actors and organisations at local, regional and national levels involved in the production, processing and com- mercialization of agricultural commodities (Spedding, 1988). Consequently, innovation capacity in the agricultural system is defined as the ability of these actors and organisations to develop new andmobilise existing competences (including knowledge, skills and experiences) to continuously identify and prioritise con- straints and opportunities for innovation in a dynamic systems context (Leeuwis et al., 2014). Following the typical system boundaries used in generic (i.e. non- agricultural) studies of innovation systems (Carlsson et al., 2002; Papaioannou et al., 2009; Wieczorek and Hekkert, 2012), we con- ceptualise the agricultural system as a combination of interrelated institutional, sectoral and technological subsystems. The institu- tional subsystem comprises different types of institutions, which are the formal and informal rules and structures that shape per- spectives and practices (Leeuwis, 2004). In this paper we examine six types of institutions; policy, research, education and training, extension, markets and politics across different aggregation levels (e.g. national, regional or district) (e.g. Cooke et al., 1997; Freeman, 1988, 1995). The sectoral subsystem is defined around a commod- ity or segments of a value chain (e.g. rice or cocoa) (e.g. Blay-Palmer, 2005; Gildemacher et al., 2009). The analysis of the sectoral sub- system seeks to understand interactions between, for instance, access to credit, inputs and services, agricultural production, post- harvest activities, trade, marketing and consumption related to the functioning of that value chain (e.g. Thitinunsomboon et al., 2008). Within the agricultural system, different sectoral subsystems can exist and interact. Technological subsystems are defined around an existing or novel technology (e.g. irrigation, mechanised weeding) or field of knowledge (e.g. integrated pest management) to address a particular problem that may well cut across different sectoral sub- systems (Carlsson and Stankiewicz, 1991; Chung, 2012; Hekkert et al., 2007). 2.3. The agricultural innovation support system The agricultural innovation support system provides the struc- tural conditions that can enable (when present) or constrain (when absent or malfunctioning) innovation within the agricultural system and its subsystems (Klein Woolthuis et al., 2005; van Mierlo et al., 2010; Wieczorek and Hekkert, 2012) (Table 2). Structural condi- tions include (1) adequate knowledge infrastructure in the form of research, education and extension, physical infrastructure and assets such as roads and vehicles, and functional communication and finance structures, (2) institutions comprise clear regulatory frame- works and their proper implementation and enforcement, (3) interaction and collaboration between multiple stakeholders in the agricultural system, and (4) stakeholder capacities (e.g. literacy and entrepreneurship) and adequate human and financial resources (e.g. number of extension officers and funds for their backstopping). The analysis of the presence and functioning of these structural con- ditions contributes to a better understanding of what constraints or enables innovation capacity in the agricultural system (e.g. limited multi-stakeholder collaboration), as well as how the structural con- ditions provided by the agricultural innovation support system stimulate or hamper this (e.g. incentive structures for different stake- holder groups to collaborate). The set-up of the agricultural innovation support system may be good at supporting incremental ‘system optimisation’ that re- produce the current state of affairs, but less good at supporting ‘system transformation’ that can lead to radical innovations. For example, the presence of an effective top-down, technology- oriented agricultural extension system can enable the dissemination of crop protection solutions through a technology transfer ap- proach. However, the existence of this system can form a constraint for the promotion of agro-ecological approaches through partici- patory, farmer-led experiments. Consequently, to achieve system transformation, both the agricultural system and the agricultural innovation support system should undergo continuous adapta- tion (Hall et al., 2004; Spielman, 2005). 2.4. Interactions between complex agricultural problems, innovation capacity in the agricultural system and the agricultural innovation support system The integrated analysis of complex agricultural problems, in- novation capacity of the agricultural system and the performance of the agricultural innovation support system can provide a coher- ent set of specific and generic entry points for innovation (Fig. 1). Specific entry points for innovations relate to those innovations that directly contribute to addressing the complex agricultural problem under study. Generic entry points for innovation related to strength- ening the innovation capacity of agricultural system and the functioning of the agricultural innovation support system. For example, to reduce fruit waste in developing countries, existing tech- nologies for conserving fruits can be adapted to fit the local context (specific entry point for innovation of the technological subsys- tem). This may trigger access to export markets (specific entry point for innovation of the sectoral subsystem) and require certification policies to supply such fruit export markets (specific entry point for innovation of the institutional subsystem). To support the devel- opment, implementation and enforcement of certification policies, the establishment of a national agricultural certification bureaumay be required (generic entry point for innovation). The existence of such a bureau can provide an incentive for investing in the export of other agricultural products, for instance, vegetables, that, in turn, can trigger the development or adaptation of conservation tech- nologies to reduce vegetable waste. The above example shows how structural adaptations of the agricultural innovation support system can enhance innovation capacity to addressing the complex agri- cultural problem under review (fruit waste), but can also have a spill- over effect on addressing other complex agricultural problems (vegetable waste). Furthermore, the agricultural innovation support system can provide conditions that support innovation in the ag- ricultural sector more generally, for instance through innovation Table 2 Structural conditions that enable or constrain innovation in systems (based on Klein Woolthuis et al., 2005; van Mierlo et al., 2010; Wieczorek and Hekkert, 2012). Structural conditions for innovation Description Infrastructure and assets Knowledge, research and development infrastructure; physical infrastructure including roads, irrigation schemes and agricultural inputs distribution; communication and financial infrastructure. Institutions Formal institutions including agricultural policies; laws; regulations; (food) quality standards; agricultural subsidies; Monitoring and Evaluation (M&E) structures; organisational mandates; market (access) and trade agreements; informal institutions such as social-cultural norms and values. Interaction and collaboration Multi-stakeholder interaction for learning and problem- solving; development and sharing of knowledge and information; public-private partnerships; networks; representative bodies (e.g. farmers association); power- dynamics. Capabilities and resources Agricultural entrepreneurship; labour qualifications; human resources (quality and quantity); education and literacy rates; financial resources. 3M.

Selection criteria for methods RAAIS is a diagnostic tool that combinesmultiplemethods of data collection. Building on existing experiences with rapid appraisal ap- proaches and (participatory) innovation systems analysis, five criteria for the selection of methods have been identified. 1. Methods should be diverse, rigorous, and be able to generate both qualitative and quantitative data. This enhances the credibility and strength of the analysis (Spielman, 2005). Qualitative data provide the basis for the identification and analysis of the different dimensions of complex agricultur- al problems, and structural conditions enabling or constraining the innovation capacity. Such data may also provide narratives regarding the underlying causes and historical evolution of constraints. Quantitative data analysis can build on this by pro- viding (descriptive) statistics and trends on, for instance, the distribution of constraints across different levels, stakeholder groups or study sites. 2. Methods should facilitate both ‘insider’ and ‘outsider’ analysis. Insider analysis implies data analysis by stakeholders who can provide highly detailed explanations of specific phenomena based on their knowledge and experiences. However, insiders such as farmers or policymakers often have an incomplete or insuffi- cient critical view of the broader agricultural system or the agricultural innovation support system. Consequently, it is im- portant to complement insider analysis by outsider analysis of data by researchers (vanMierlo et al., 2010). By combining insider and outsider analysis, the delineation of the systems boundar- ies is done in a participatoryway, by stakeholders and researchers. 3. Methods should be able to target different stakeholder groups across different levels. When studying complex agricultural prob- lems, it is essential to include different groups of stakeholders, their perceptions on what constitutes the problem, and what are perceived feasible or desirable solutions (Faysse, 2006; Ortiz et al., 2013). 4. Methods should be able to target stakeholders individually, in homogeneous groups and in heterogeneous groups so as to capture individual, group and multi-stakeholder perceptions on problems and solutions. Discussion and debate in both homo- geneous and heterogeneous stakeholder groups generally provide a rich analysis of complex problems and potential solutions. Fur- thermore, multi-stakeholder interaction may reveal asymmetric power-relationships that are necessary to understand innova- tion capacity in the agricultural system. On the other hand, power-relationships, group pressure, or mutual dependencies between stakeholders may result in situations where sensitive Fig. 1. Schematic representation of the dynamic interactions between complex agricultural problems (multiple dimensions, multi-level interactions and multi-stakeholder dynamics), innovation capacity of the agricultural system (including its institutional, sectoral and technological subsystems), and the structural conditions within the ag- ricultural innovation support system that can enable or constrain innovation capacity in the agricultural system (infrastructure and assets, institutions, interaction and collaboration, and capabilities and resources). RAAIS provides insight into the current state of the system (on the left). RAAIS provides specific and generic entry points for innovation that can guide a transition towards the desirable state of the system (on the right) in which the complex agricultural problem is addressed, and the innovation capacity in the agricultural system has increased. Generic entry points for innovation can have a spill-over effect in terms of addressing other complex agricultural problems than the one under review. 4 M. Schut et al./Agricultural Systems 132 (2015) 1–11 questions are avoided, or receive socially desirable responses. Methods that target stakeholders individually are more likely to provide insights in such questions (International Institute for Sustainable Development, 2014). 5. Methods together should provide sufficient detail on the complex agricultural problem under review, the innovation capacity in the agricultural system, and the functioning of the agricultural innovation support system (World Bank, 2012). Combining different types of methods and data collection tech- niques provides an opportunity to triangulate and validate data. Depending on the nature of the agricultural problem under review and the available resources and time, different types of data col- lectionmethods can be used for RAAIS, taking into account the above criteria for method selection. 3.2. Methods of data collection Based on the five criteria, four complementary methods for data collection were selected to be part of RAAIS (Table 3). 3.2.1. Multi-stakeholder workshops Multi-stakeholder workshopsmainly focused on the insider anal- yses of innovation capacity in the agricultural system and the structural conditions provided by the agricultural innovation support system. A participatory workshop methodology facilitates differ- ent groups of stakeholders to – individually and in homogeneous and heterogeneous groups – identify, categorise and analyse con- straints for innovation in the agricultural system. Depending on the type of problem, workshops can be organised with stakeholders rep- resenting national, regional and/or district levels or, for instance, across different study sites where a specific problem is eminent. To keep the workshops manageable, and to stimulate interaction and debate, the participation of a maximum of 25 participants per work- shop is proposed; for instance consisting of five representatives of the five different stakeholder groups in Table 1. As much as possi- ble, each group should be a representative sample with respect to, for instance, gender, age, income, or ethnic groups. The work- shops should be held in the language that all participants speak, and be facilitated by someone who is familiar with the cultural norms, has affinity with the problem, and understands the reali- ties of the different stakeholder groups. The proposed workshop methodology consists of 13 Sessions subdivided into three catego- ries, with each their own focus: (1) identifying constraints, (2) categorising constraints, and (3) exploring specific and generic entry points for innovation. Figure 2 and Table 4 provide an overview of the 13 Sessions, their sequence and relations, and their specific ob- jective in RAAIS. Workshops are designed to take approximately 1 day. Besides the facilitator, a note-taker documents the outcome of the differ- ent sessions and captures discussions among participants. Workshop facilitation and note-taking protocols ensure that the workshop organisation, facilitation and documentation is standardized, which is essential for comparing or aggregating the outcomes, for in- stance, across different study sites. A crucial element in the workshops is the use of coloured cards. At the start of the workshop (Session 1), each of the stakeholder groups is assigned a different colour. During Session 2, each par- ticipant individually lists five constraints or challenges they face in their work and writes them down on their coloured cards. If five stakeholder groups are equally represented, this results in 125 cards. During Session 3, the participants discuss within their stakehold- er groups the listed constraints, explore overlapping issues and jointly develop a stakeholder group top-5. If necessary, constraints can be reformulated based on discussions within the group. Each of the stakeholder groups use their top-5 throughout the rest of the Ta bl e 3 M et h od ol og ic al fr am ew or k in di ca ti n g h ow di ffe re n t m et h od s fo r da ta co ll ec ti on co rr es p on d w it h th e se le ct io n cr it er ia fo r m et h od s.

Schut et al./Agricultural Systems 132 (2015) 1–11 sessions during the workshop; hence 25 cards (five cards per stake- holder group) (Photo 1–4). The use of the coloured cards facilitates the analysis of differ- ent sessions during and after the workshops. As the cards are coded and recycled throughout the successive sessions, photographs can be taken to capture the results (for example Photo 1 and 4). Such photographs can be analysed after the workshop, and can also be used to validate the note-taker’s data. Furthermore, the cards provide insight into the relations between constraints identified by differ- ent stakeholder groups (Photo 2 and 3). Combining the results from different sessions can stimulate integrative analyses, for instance, combining data resulting from Sessions 5 and 6 provides insight in the structural conditions for innovation across different levels. Sim- ilarly, the outcome of Sessions 7 and 11 can be compared to triangulate the data, as both seek to identify key constraints for in- novation in the agricultural system. 3.2.2. Semi-structured in-depth interviews To guide the semi-structured interviews, a topic list is pre- pared and fine-tuned for each interview. Using a topic list provides a degree of flexibility to identify and to anticipate interesting storylines related to the problem under review, and allows valida- tion of data that was gathered during previous interviews or during the workshops. Interviews should take a maximum of 1 hour, en- suring a high level of attentiveness of both the respondent as well as the interviewer. Sampling of interview respondents should follow a stratified approach, to ensure that stakeholders representing dif- ferent study sites, different stakeholder groups, and different administrative levels are included. Within those strata, respon- dents can be selected purposive or based on snowball sampling where interview respondents make suggestions for who else should be included in the sample (Russell Bernard, 2006). The sample size can be based on the concept of “saturation,” or the point at which no new information or themes are observed in the interview data (Guest et al., 2006). Interviews can be recorded and transcribed elec- tronically. From an ethical point of view, interviewees should give permission for interviews to be recorded, and researchers should ensure confidentiality of all interview data. Recordingmay not always be desirable, as the voice recorder can create a barrier between the researcher and the respondent, especially when it comes to dis- cussing politically sensitive issues. Instead of recording, detailed notes can be taken and transcribed electronically. The transcribed inter- views can be coded. Ideally, interviews are conducted and coded by two researchers, which will enhance the quality of the analysis. 3.2.3. Surveys Based on the workshops and the interviews, some of the con- straints may be eligible for broader study among specific groups of stakeholders through the use of surveys. Such surveys may provide more insights in, for example, the socio-economic impacts of climate change on smallholder agriculture in specific regions, the quality of agricultural extension received by farmers in ad- dressing complex agricultural problems, or access to agricultural inputs for male or female headed households. Surveys are not nec- essarily limited to farmers, but can also be conducted with any of the other stakeholder groups involved. For the data to be comple- mentary, surveys should be completed in the same study sites as where the workshops were organised and among a representative sample of the targeted stakeholder group. To achieve that, a strati- fied random sampling strategy can be used to identify respondents across different study sites, levels or stakeholder groups. A (effi- cient) sampling method that allows for optimal allocation of resources can be used to determine the sample size (e.g. Whitley and Ball, 2002). 3.2.4. Secondary data collection Secondary data are written data with relevance for the analy- sis of the complex agricultural problem, innovation capacity of the agricultural system or the functioning of the agricultural innova- tion support system. Examples are policy documents, project proposals and reports, laws or legal procedures, project evalua- tions, curricula for agricultural education and training, (agricultural) census and organisational records such as charts and budgets over a period of time. The sampling of secondary data is not clear cut. Key agricultural documents such as agricultural policies or agri- cultural research priorities should be included. These documents can refer to other relevant data. Furthermore, secondary data is often provided during, or following interviews. Insights from secondary data can be verified in interviews with stakeholders (e.g. the extent to which policy is implemented and enforced). 4. RAAIS’ ability to provide specific and generic entry points for innovation and lessons learnt from its application We tested RAAIS through a case study aimed at analysing con- straints and opportunities for innovation to effectively address parasitic weeds in rain-fed rice production systems in Tanzania (April–October 2012) and Benin (June–August 2013). The results from RAAIS in Tanzania are elaborated in Schut et al. (2014c). Data were gathered across national, zonal, regional and district levels. Multi- stakeholder workshops (with 68 participants in Tanzania and 66 participants in Benin) were organised in three study sites (dis- tricts) in Tanzania and Benin where parasitic weeds are eminent. In-depth interviews were held with representatives of national-, zonal-, regional- and district-level representatives of farmer coop- eratives and associations, NGO/ civil society, private sector, government and research and training institutes (42 in Tanzania, 65 in Benin). Across the three study sites in the countries, a Session 2 Session 3 Session 1 Categorising constraints Exploring specific and generic entry points for innovation Identifying constraints Fig. 2.

Schut et al./Agricultural Systems 132 (2015) 1–11 socio-economic farmer survey (152 in Tanzania, 182 in Benin) was held to study the impact of parasitic weeds on rain-fed rice farming (see N’cho et al., 2014 for more information). In Tanzania, a farmer- extensionist survey (120 farmers, 30 agricultural extension officers) was held to explore the effectiveness of the national agricultural ex- tension policy across the three study sites (see Daniel, 2013 for more information). Additionally, for both countries, secondary data in- cluding crop protection, extension and general agricultural policy, national research priorities, agricultural census and agricultural train- ing curricula were analysed. Data gathering and initial analysis took around three months for each of the countries, and involved two researchers. We first conducted the in-depth interviews, followed Table 4 The 13 Workshop Sessions subdivided over the three categories, and their specific activities and objectives in the RAAIS.

Schut et al./Agricultural Systems 132 (2015) 1–11 by the multi-stakeholder workshops. In Tanzania, both the socio- economic farmer survey and the farmer-extensionist survey were held after the interviews and workshops. In Benin, the socio- economic farmer survey was held preceding the in-depth interviews and workshops. Secondary data collection occurred throughout the fieldwork. Below, we will further reflect on the main objectives of RAAIS, as well as provide recommendations for further improve- ments and use of RAAIS, using our experiences from Tanzania and Benin. 4.1. RAAIS’ ability to provide specific entry points for innovation to address complex agricultural problems RAAIS contributed to an integrated understanding of different problem dimensions, multi-level interactions, andmulti-stakeholder dynamics related to parasitic weed problems. With regard to the different problem dimensions, interviews demonstrated a poten- tial relation between, for example, the preference for growing local, aromatic rice varieties (social-cultural dimension), the low capac- ity of farmer to purchase certified seeds (economic dimension), and the spread of parasitic weed seeds through the local rice seed system (technological dimension). Additionally, analysis of workshop data revealed how the untimely and insufficient availability of agricul- tural inputs provided by the government (institutional dimension) and limited interaction and collaboration among networks of key stakeholders (political dimensions) form additional bottlenecks for addressing such problems. It created awareness that describing and explaining complex agricultural problems, and exploring and de- signing solutions is unlikely to be successful if the different problem dimensions are analysed and treated separately (Hall and Clark, 2010; Spielman et al., 2009). Data gathering across different levels (national, region, and dis- trict level) enabled the analysis of the interactions and (mis)matches between different levels (Cash et al., 2006). An example that emerged during the workshops and the interviews is Tanzania’s national export ban, that prohibits export of agricultural produce (e.g. of rice) as long as the country has not been declared ‘food secure’. This na- tional export ban influences local market prices, and consequently, also farmers’ willingness and ability to invest in, for example, pur- chasing agricultural inputs such as fertilizers and seeds (e.g. Poulton et al., 2010). This, in turn, provided an opportunity to identify entry points for innovation across different levels, which has been iden- tified as a critical factor for addressing complex agricultural problems (e.g. Giller et al., 2008, 2011). As expected, and confirming previ- ous reports (e.g. van Mierlo et al., 2010), the participatory analysis of multi-level interactions showed that stakeholders (insiders) often identify constraints at the level they represent (Schut et al., 2014c). This was complemented by our analysis as researchers (outsiders) of the multi-level interactions regarding the parasitic weed problems. Photo 1–4.

Schut et al./Agricultural Systems 132 (2015) 1–11 The involvement of different groups of stakeholders was essen- tial for enhancing the credibility, validity and quality of RAAIS, as well as for delineating the boundaries of the agricultural system and the agricultural innovation support system, which is considered a key challenge when using AIS approaches to analyse complex ag- ricultural problems (Klerkx et al., 2012b). Furthermore, stakeholder participation provided a better understanding of the feasibility and acceptability of solutions for stakeholder groups. Althoughwe believe that the stakeholder groups included in the testing of RAAIS (Table 1) provide a good starting point, other stakeholder groups (for in- stance the media) may be included in the sample (e.g. Ortiz et al., 2013) depending on the type of complex agricultural problem under review. The triangulation of data resulting from the differentmethods enabled us to validate findings, and to verify strategic communi- cation by stakeholders, for instance, to verify how the extension system as described by policymakers in interviews, functioned in reality according to surveyed farmers. 4.2. RAAIS’ ability to provide generic entry points for innovation RAAIS demonstrates interactions between complex agricultur- al problems, innovation capacity of the agricultural system – consisting of institutional, sectoral and technological subsystems – and the agricultural innovation support system. For example, ap- plying fertilizer (technological subsystem) in rain-fed rice production is seen as a promisingmanagement strategy to reduce infection levels of Rhamphicarpa, one of the parasitic weeds involved in the study, andmitigate negative effects of the parasite on rice yields (Rodenburg et al., 2011). However, as was highlighted during the RAAIS work- shops in both in Benin and in Tanzania, fertilizers are difficult to access in rural areas. In Benin, there is no well-developed private agro-dealer network and distribution infrastructure to support the supply of agricultural inputs. Furthermore, interviews showed that the public extension and input supply systems in Benin focus on the cotton sector, rather than on cereal crops (sectoral subsys- tems). In Tanzania, a private agro-dealer network and distribution infrastructure exists, but structures controlling the quality of fer- tilizers (institutional subsystem) are functioning sub-optimally according to interviewed government officials. In some areas, fake agro inputs are dominating the market, resulting in a limited trust and willingness to invest in applying fertilizer according to farmer representatives who participated in the workshops. The example shows how the absence or poor performance of fertilizer distribu- tion infrastructure, limited farmer-extensionist interaction and lack of functional institutions for quality control (being structural con- ditions for innovation) constrain the innovation capacity in the agricultural systems and its technological (in this case fertilizer) and sectoral (the rice value chain) subsystems. Another example is based on secondary data analyses that demonstrated the lack of an op- erational strategy to address parasitic weeds in Tanzania and Benin. In both the interviews and workshops, stakeholders highlighted the general lack of interaction and collaboration between stakehold- ers in the agricultural sector (being a structural condition for innovation) as one of the main reasons for the absence or poor im- plementation of parasitic weed and other agricultural policies and strategies. The aforementioned examples demonstrate how RAAIS can support the identification of generic entry points for innovation. Such innovations can directly contribute to addressing the complex ag- ricultural problem under review, but can also have a spill-over effect in terms of addressing broader constraints that hamper the inno- vation capacity in the agricultural system. For example, the lack of stakeholder interactions and collaboration in the agricultural system can provide an entry point for the adaptation of the structural conditions in the broader agricultural innovation support system, for example through investments in innovation brokers or multi-stakeholder platforms (Kilelu et al., 2013; Klerkx et al., 2010). Such structural adjustments can facilitate multi-stakeholder col- laboration in tackling parasitic weed as well as other complex agricultural problems. 4.3. Lessons learnt from applying RAAIS and recommendations for further improvement Based on our experiences in Tanzania and Benin, we recom- mend conducting RAAIS in an interdisciplinary team of researchers with expertise on different dimensions of complex agricultural prob- lems and on different data collection methods (Hulsebosch, 2001). Other suggestions include the experimentation with other combi- nations of methods, and on different types of complex agricultural problems. The workshop methodology could be made more inter- active, in the sense of directly feeding back results of the sessions to participants to stimulate reflection and validate analyses during the workshops. Post-workshop surveys could provide additional insight into whether stakeholders felt they could freely raise and discuss their ideas and needs. The multi-stakeholder workshops, but also the surveys, pre- sented a rather static picture of the complex agricultural problem under review and the innovation capacity of the agricultural system in which the problem is embedded. However, initial workshops and surveys could function as a baseline, to which future workshops and surveys can be compared. Other methods such as secondary data analysis or in-depth interviews present a more dynamic image of how, for example, collaborations between stakeholders evolve over the years. Our experiences in Tanzania and Benin show that ensur- ing social differentiation amongworkshop participants, interviewees and survey respondents (e.g. of different gender of age) was chal- lenging, as, for example, the majority of workshop participants were male. SpecificWorkshop Sessions could havemore attention for cat- egorisation and priority setting by different gender or age groups. The facilitation of the multi-stakeholder workshops ensured that different stakeholder groups could raise and discuss their ideas (Hulsebosch, 2001). Despite such efforts, unequal power relations and differences in the ability to debate and negotiate that inher- ently exist between groups may have played a role. In line with our expectations, politically sensitive issues were more freely dis- cussed in individual interviews as compared to multi-stakeholder setting. The combination of different methods of data collection was essential. In terms of the sequence of data collection, we recom- mend to first conduct and analyse the RAAIS multi-stakeholder workshops to identify constraints, and subsequently conduct the in-depth interviews and surveys that can provide more insight in the distribution and underlying root causes of these constraints. The workshops then provide a ‘fast-track’ approach to identifying entry points for innovation, that can subsequently be validated and explored in more detail using the in-depth interviews and stake- holder surveys. This would furthermore increase the ‘rapidness’ of RAAIS as a diagnostic tool. An updated version of the RAAIS multi-stakeholder workshops has been used to identify constraints, challenges and entry points for innovations related to the ‘sustainable intensification of agri- cultural systems’ in Burundi, the Democratic Republic of Congo, Rwanda, Nigeria and Cameroon under the CGIAR Research Pro- gramme for the Humid Tropics (Humidtropics) (Schut and Hinnou, 2014). Several of the recommendations made in this paper, includ- ing the revised sequence of methods for data collection and the use of post-workshop participant questionnaires, have been imple- mented and tested successfully. Some of the bottlenecks identified, such as social differentiation (e.g. gender and age groups) among workshop participants remained problematic and require further attention. At the end of the Humidtropics RAAIS workshops, 9M. Schut et al./Agricultural Systems 132 (2015) 1–11 participants developed action plans to address the prioritised con- straints (Workshop Session 13). This required an extension of the workshops of half a day. The development and implementation of the action plans forms an important element for continued stake- holder collaboration in multi-stakeholder platforms. 5. Conclusions This paper demonstrates the potential of RAAIS as a diagnostic tool that can support and guide the integrated analysis of complex agricultural problems, innovation capacity in the agricultural system, and the performance of the agricultural innovation support system. RAAIS combines multiple qualitative and quantitative methods, and insider (stakeholders) and outsider (researchers) analyses which allow for critical triangulation and validation of the gathered data. Such an analysis can provide specific entry points for innovations to address the complex agricultural problem under study, and generic entry points for innovation related to strengthening the innova- tion capacity of agricultural system and the functioning of the agricultural innovation support system. Recommendations for further improvement include using RAAIS for the analysis of other types of complex agricultural problems, using other combinations of methods of data collection, and providing di- rectly feedback to workshop participants to stimulate reflection and validate workshop outcomes. An adapted sequence of data collec- tion methods in which workshops provide a ‘fast-track’ approach to identifying entry points for innovation, followed up by more in- depth interviews and stakeholder surveys would increase the RAAIS’ diagnostic capacity. The participatory development of concrete action plans based on RAAIS can provide a basis for continued multi- stakeholder collaboration to operationalise and implement specific and generic entry points for innovation.
