In recent years, governments, donors, and NGOs have increasingly embraced value chain development (VCD) for stimulating economic growth and combating rural poverty. In line with the rise in interest, there has been a proliferation of guides for VCD. The purpose of this paper is to present the results of a review of 11 guides for value chain along six different dimensions, ranging from objectives and value chain definitions to monitoring impact. The paper concludes with suggestions for the use of guides based on local needs and context, and recommendations for future guide development.

The review compares the concepts and methods endorsed and it assesses the strengths and limitations of the guides for steering development practice.

Overall, the guides provide a useful framework for understanding markets and engaging with chain stakeholders, with a strong emphasis on strengthening institutions and achieving sustainability of interventions. However, the guides often lack discussions on the conditions necessary at different levels for VCD to advance development objectives and achieve that sustainability. The guides are designed to be implemented largely independently of the specific context, in which the chain is situated, despite the major implications context has for the design of interventions and overall success of the chain. Attention to mutual learning, whether related to tool design or the outcomes and impacts of VCD interventions, is limited.

More critical reflection and debate is needed on the design of guides for VCD. The authors suggest three areas for this reflection and debate: concepts, methods, and tools for addressing the needs of the poor in value chains; tools for addressing variations in the context; and mechanisms for mutual learning on the design and implementation of VCD.

The paper concludes with various recommendations for guide authors and donors that support VCD.

The purpose of this paper is twofold: first, to take stock of the current state of knowledge about inclusive value-chain development (VCD) in the context of international agricultural research; and second, to draw out the implications for future research and action.

This paper is based on a review of recent research papers authored by professionals affiliated with international agricultural research centers and their partners in Africa, Asia, and Latin America.

The studies reviewed in the paper identify the opportunities emerging from new and expanding markets for agricultural products and challenges to smallholder participation in these markets. It identifies key attributes of successful value-chain interventions, emphasizing the importance of combining value-chain approaches with other approaches, including those emerging from innovation systems and rural livelihoods frameworks. Methods are offered for evaluating complex value-chain interventions.

The paper summarizes the state of knowledge as of early 2016 in a dynamic field. Important contributions to knowledge may have been made since then.

The paper summarizes the state of knowledge in the field, and identifies emerging issues and policy implications, knowledge gaps, and priorities for future applied research.

The value chain is an essential management tool for the elaboration of strategic organizational planning. However, there are few published works providing methods for the development of value chains. This research aims to present a model to develop the value chain for the public sector.

Action research was used with case study in the evaluation step.

This research presents a model for value chain development along seven steps, covering data collection planning to the formalization of final product acceptance. The model suggests executing these seven steps in three iteration levels: operational, tactical and strategic. Through case studies, six practical insights were also highlighted in this work.

Given the absence of related work, one of the limitations is the lack of comparison with other methods of value chain development in the public sector.

There are practical guides to value chain development in the public sector; however, to the best of authors’ knowledge, such guides have not been developed using research methods. In the literature, no works provide details on how value chain can be developed in the public sector. In addition, the constraints of face-to-face contacts during the COVID-19 pandemic led the research team to conduct remotely the model's development and evaluation in the case studies. The model presents elements that enable value chain development without face-to-face contact between the execution team and public institution's stakeholders.

The purpose of this paper is to investigate borrowing motivation, credit access barriers and their impacts on income of smallholder farmers engaging in cinnamon value chain development in Northwestern Vietnam.

A multistage sampling technique using a structural questionnaire and in-depth interviews was applied for collecting primary data from farmers and relevant stakeholders. The Propensity Score Matching was employed to analyze access barriers and examine whether relaxing these barriers can improve farmer income. To deal with the issue of model uncertainty and further increase the robustness of results, Bayesian model average and the bootstrapping approach were applied.

To fulfill the certain quality standards of cinnamon products which are later used in the medicinal and food industry, farmers as primary producers need credit for intensive investment to increase the value of their products. Still, there are 25.36 percent of farmers who have access constraints to formal credit. In the credit received group, 24.56 percent have not received full credit as demanded. Access problems are relevant to lack of collateral, lack of bank account holdings, inconvenient access to roads, weak chain linkage and limited organic farming. Removing credit access barriers can improve the income for farmers from cinnamon farming activities.

More detailed information on the conditions under which credit serves a more important role in creating value addition for cinnamon products can help the government establish more effective credit policies.

Great attention should be paid to smallholder farmers as primary producers in the chain for sustainable value chain development in developing and emerging economies. Policy interventions should facilitate access to bank accounts, speed up the process of granting residential land use certificates, certify organic farming and upgrade the road system. Strengthening the chain linkage can enhance smallholder farmers’ capacity to obtain credit through value chain lending development.

Empirical studies on agricultural credit from the perspective of value chain development remain scarce. A better understanding of credit access constraints allows for the positing of recommendations for policy makers to facilitate value chain lending and a medicinal plant-based agro-forestry system in similar situations.

The purpose of this paper is to look at the ever-popular, “value-chain approach” for linking smallholder farmers to high value export markets. Conventional wisdom says that value chains undertaken for development purposes redistribute risk and provide benefits and services to participants that are otherwise difficult or impossible to obtain. The authors take a farmer-centric approach and ask farmers participating in these higher value chains if they perceive greater, or different risks and compare results to their conventional counterparts. The authors also ask what benefits they associate with participation and if they believe they believe those benefits are exclusive to value chain participation.

The authors collect data from growers in three different cocoa value chains in Ashanti, Ghana. These chains include one focussed on certified production practices (Rainforest Alliance), one that focussed on high-value product characteristics (Fine Flavor) and a conventional chain, which serves as counterfactual.

The paper finds differences in perceptions of participation risks and benefits – particularly among price risks – that appear to filter based on value chain membership. However, for many risks, value chain participation seems to do little to redistribute potential production shocks. With some exceptions, growers report that many of the benefits they enjoy as a result of participation could feasibly be accessed by other sources.

The limitations of this paper are related to sample size. This was managed from a statistical perspective.

The authors explore how these results might impact the sustainability of the value chain approach and encourage donors and development agencies to be thoughtful and critical about measuring how farmers perceive new market opportunities.

The authors believe that this is the first paper prepared to critically investigate the perceived benefits of value chains.

The purpose of this paper twofold: first, to review the current state of knowledge regarding local value chain (LVC) interventions in the context of international agricultural research and development; and, secondly, by synthesising the empirical findings from LVC projects, to provide guidance for future research and intervention design.

This paper utilises systematic review and qualitative meta-synthesis guidelines to review and synthesise recent research papers and case studies dealing specifically with the development of LVCs, authored by professionals affiliated with development agencies and international research consortiums.

The paper identifies a novel two-phase characterisation of LVC interventions. Phase 1 identifies opportunities for interventions, which are characterised as typologies and presented upon a spectrum of value chain functionality from underdeveloped to mature. Phase 2 is the selection and implementation of strategies to achieve the identified opportunities from Phase 1, and the paper characterises these strategies per the domain of value chain functionality which they target.

The interaction between context, socio-economic constraints and intervention strategies is still a poorly understood feature of value chain interventions, and the paper posits that a greater understanding of these interactions is crucial to the success of value chain interventions.

The paper provides the first synthesis of LVC interventions, while outlining research priorities and knowledge gaps required to design interventions which are consummate to the context and functionality of a prioritised chain.

Between 2006 and 2011, Nicaragua shipped an average of US$9.4 million per year of smallholder-produced fresh taro (Colocasia esculenta) to the USA; however, by 2016, the US market for Nicaraguan taro had effectively collapsed. The purpose of this paper is to analyze the short-lived taro boom from the perspective of complex adaptive systems, showing how shocks, interactions between value chain actors, and lack of adaptive capacity among chain actors together contributed to the collapse of the chain.

Primary data were collected from businesses and smallholders in 2010 and 2016 to understand the actors involved, their business relations, and the benefits and setbacks they experienced along the way.

The results show the capacity of better-off smallholders to engage in a demanding market, but also the struggles faced by more vulnerable smallholders to build new production systems and respond to internal and external shocks. Local businesses were generally unprepared for the uncertainties inherent in fresh horticultural trade or for engagement with distant buyers.

Existing guides and tools for designing value chain interventions will benefit from greater attention to the circumstances of local actors and the challenges of building productive inter-business relations under higher levels of risk and uncertainty.

This case serves as a wake-up call for practitioners, donors, researchers, and the private sector on how to identify market opportunities and the design of more robust strategies to respond to them.

This paper systematically reviewed the contributions of the recent Nigerian government agricultural policies and the impacts on the agricultural value chain system in line with the structural transformation of the sector and the Nigeria's vision 20:2020. The study also suggest strategies to upgrading various segments of the agricultural value chain and argue that Nigeria's agricultural sector requires huge investments and innovative ideas to increase production and create value addition across the most profitable areas of the value chain.

The authors systematically present evidences and data from the Central Bank of Nigeria (the apex monetary authority of Nigeria) and Nigerian Bureau of Statistics (oversees and publishes statistics for Nigeria) to estimate the impact of Government agricultural policies on the value chains system.

The study discovers that the various recent government policy interventions to tackle the austere challenges in the agricultural sector are yet to yield much significant solution. Given to the dwindling performance of the sector, the Nigerian agricultural value chain is somewhat affected with systemic and services gaps which underpin the market failures (missing markets and weak markets), although the agricultural value chain has the potential of triggering economic growth in a higher scale with a trickle-down effect to other sectors of the Nigerian economy.

Overall, the findings indicate strategies to upgrading the production and processing segments of the agricultural value chain and argues that Nigeria's agricultural sector requires huge investments and innovative ideas to increase production and create value addition across the most profitable areas of the value chain.

The study proves that enhancing value addition in the agricultural sector is imperative to achieving triple-benefits of increasing productivity by building resilient systems that leverage on finance opportunities, deepening economic inclusive growth and achieving great milestones.

This study is the first attempt to focus on agricultural value chain system in line with the structural transformation and the Nigeria's vision 20:2020.

The purpose of this paper is to introduce a new conceptual framework for smallholder value chains based on complex adaptive systems.

The authors review the application of the framework to three case studies and explore their implications. The authors reflect on the value of a framework based on complex adaptive systems compared to alternative frameworks.

The authors argue that the dynamics of smallholder value chains have received insufficient attention.

By focusing on these dynamics and on the capacity for adaptation among value chain actors the framework provides a new perspective on smallholder value chains.

Complex adaptive systems provide a useful framework for analyzing value chain dynamics.

The aim of this paper is to evaluate how Estonian enterprises understand their position in the value chain, and to explore what kind of behaviour patterns correspond to the different positions. It also aims to focus on the question of whether and how Estonian enterprises see the need to improve their position in the value chain.

The approach is based on an empirical study in the course of which original interviews were conducted on the basis of a common plan (primary sources), and expert opinions were gathered on the basis of earlier studies. Two kinds of sources were analyzed to obtain an overview of the situation in Estonian companies in respect to strategy, and more specifically how companies evaluate their position in the value chain and what their aspirations for future are. First, the figureheads from the enterprises were interviewed in 14 enterprises. Second, expert assessments were drawn up about 25 enterprises. Those compiling the expert opinions possessed prior direct contacts with the enterprises under focus.

First, it was discovered that Estonian enterprises presented three types of behaviour patterns along with their interest in and/or potential for changing their position in the value chain. Second, several behavioural patterns were indicated by what the figureheads had to say about the current economic situation. Third, the main problems in Estonian enterprises were identified.

The study has limitations due to the number of companies that were investigated, and therefore the authors also admit a certain degree of subjectivity in the defining of the behaviour patterns. Nevertheless, this study highlights various issues that Estonian enterprises consider in respect to strategy.

The main value of the paper is its contribution to our understanding of which factors impact the development of Estonian enterprises. This knowledge allows us to analyze how organizations from former Soviet bloc countries can better manage their position in the value chain.
