  • Persistent indebtedness in the global cocoa chain

    Open Access•Faustina Obeng Adomaa, Sietze Vellema•ARTICLE•The Journal of Peasant Studies•2026

    Credit–debt relations between producers and so-called exploitative traders are considered a key cause of producer indebtedness. This fuels interventions to eliminate exploitative traders in commodity chains, yet alternative arrangements often fail. Therefore, indebtedness persists. This paper critically examines the conditions and practices that produce and reproduce relations of lending and borrowing and consequently indebtedness, which are clos…

  • Contested Coffees

    Open Access•Claudia Oviedo-Rodríguez, Kees Jansen et al.•ARTICLE•The Journal of Development Studies•2025•Citada por: 1•Referencias: 30

    This paper analyses a political debate that has emerged in Mexico regarding cultivation of two coffee species: arabica, which generates high quality coffee, and robusta, which generates high yields, but is of lower quality than arabica. Many actors in Mexico, including state agencies, coffee farmer organisations, and scholars, consider improving the quality of arabica to be an ideal development pathway for small farmers. However, despite strong s…

  • Incorporation of different types of farmers into different coffee markets

    Open Access•Claudia Oviedo-Rodríguez, Kees Jansen et al.•ARTICLE•Canadian Journal of Development…•2024•Citada por: 2•Referencias: 24

    Many development organizations aim for greater incorporation of farmers into the market; however, global value chain scholars warn that farmers may be adversely incorporated and advise to analyse the terms by which farmers are incorporated. This paper sheds light on the dynamics of value chains by showing how the terms by which farmers are incorporated into the market vary significantly depending on the type of farmer and market. To generate bene…

  • Beyond the Formal-Informal Dichotomy

    Open Access•D M Vernooij, Sietze Vellema et al.•ARTICLE•The Journal of Development Studies•2023

    The triangle of dairy intensification, commercialisation and market formalisation is promoted to address the challenges of food and nutrition security (FNS) and climate change. This article questions the need for formalisation to reach intensification and commercialisation objectives in Kenya. Moving beyond the binary perception of milk markets as either ‘formal’ or ‘informal’, we investigate a repertoire of milk-collection practices and address …

  • Navigating competing demands in monitoring and evaluation

    Open Access•Marijn Faling, Greetje Schouten et al.•ARTICLE•Evaluation•2023•Referencias: 13

    Evaluation in complex programs assembling multiple actors and combining various interventions faces contradictory requirements. In this article, we take a management perspective to show how to recognize and accommodate these contradictory elements as paradoxes. Through reflective practice we identify five paradoxes, each consisting of two contradicting logics: the paradox of purpose—between accountability and learning; the paradox of position—bet…

  • Connecting the Concepts of Frugality and Inclusion to Appraise Business Practices in Systems of Food Provisioning

    Open Access•Sietze Vellema, Greetje Schouten et al.•ARTICLE•Journal of Agricultural and…•2023•Referencias: 19

    Small and medium size business enterprises (SMEs) are the linchpin in systems of food provisioning in sub-Saharan Africa. These businesses occupy the middle of the agri-food chain and face a food security conundrum: they must ensure that smallholder producers of limited means can operate under fair terms while low-income consumers are supplied with affordable and nutritious food. This task becomes even more challenging when resources are scarce. …

  • Justice and Inclusiveness

    Open Access•Faustina Obeng Adomaa, Sietze Vellema et al.•ARTICLE•Journal of Agricultural and…•2022•Referencias: 11

    Pressure from the public and non-governmental organisations is pushing lead companies in the cocoa and chocolate sectors towards becoming more environmentally sustainable and socially just. Because of this, several sustainability programmes, certification schemes and delivery initiatives have been introduced. These have changed the relationship between chocolate companies, cocoa exporters, and small-scale farmers. This paper observes how large co…

  • The adoption problem is a matter of fit

    Open Access•Faustina Obeng Adomaa, Sietze Vellema et al.•ARTICLE•Agriculture and Human Values•2022•Citada por: 2•Referencias: 5

    Good Agricultural Practices (GAPs) are central to sustainability standards and certification programmes in the global cocoa chain. Pruning is one of the practices promoted in extension services associated with these sustainability efforts. Yet concerns exist about the low adoption rate of these GAPs by smallholder cocoa farmers in Ghana. A common approach to addressing this challenge is based on creating enabling conditions and offering appropria…

  • Monitoring Systemic Change in Inclusive Agribusiness

    Open Access•Sietze Vellema, Greetje Schouten et al.•ARTICLE•IDS Bulletin•2022

    Evaluations of private sector development programmes look at what changed to the workings of the system, and whether these changes are scalable, resilient, and sustainable. We present an evaluation lens that primarily qualifies changes to the systemic nature of food provisioning in markets. It converts theoretical frameworks into ‘antennae’ receptive to early signs of systemic effects of inclusive agribusiness that fosters food and nutrition secu…

  • Introduction

    Open Access•Giel Ton, Sietze Vellema•ARTICLE•IDS Bulletin•2022

    The private sector has become an important partner in development interventions that aim to make market systems more favourable for smallholders and low-income consumers of food. How to evaluate these inclusive business programmes is the central theme of this IDS Bulletin. It presents real-world experiences of practitioners and academics using theory-based evaluation. This introductory article highlights the approaches and methods used to assess …

  • How institutions governing the economic middle in food provisioning are reinforced

    Open Access•Mirjam Schoonhoven-Speijer, Sietze Vellema•ARTICLE•Journal of Rural Studies•2020•Citada por: 4•Referencias: 19

    A diverse ensemble of intermediary traders jointly shape access to food. • The food cluster is recognized internally and externally as an institution for trade. • A practice-oriented approach demonstrates how institutions are self-reinforced. • Assembling a variety of practices is a condition for consolidating the cluster. • An institutionally viable food cluster enables access to food in rural settings

  • The Triviality of Measuring Ultimate Outcomes

    Open Access•Giel Ton, Sietze Vellema et al.•ARTICLE•IDS Bulletin•2014•Citada por: 2•Referencias: 17

    Sustainability standards and certification schemes have been promoted as a market-driven instrument for realising development impacts and receive public funding. As a result, companies, NGOs and supporting donors and governments want to know if these ambitions have been fulfilled. Their tendency is to commission household surveys to assess net effects of certification in areas such as poverty, productivity and food security. This article argues t…

  • Value chains, partnerships and development

    Open Access•Sietze Vellema, Giel Ton et al.•ARTICLE•Evaluation•2013•Citada por: 4•Referencias: 10

    Partnerships between companies and non-governmental organizations that aim to incorporate smallholder farmers into value chains are increasingly being promoted as a way of pursuing development goals. This article investigates two case studies of such partnerships and the outcomes they achieved in order to refine the rationale underlying such interventions. In two case studies in Uganda and Rwanda, we documented the sequences of events within such…

    Open Access•Sietze Vellema, Saturnino M Borras Jr et al.•ARTICLE•Journal of Agrarian Change•2011•Citada por: 22•Referencias: 23

    The decades-old conflict in Mindanao, southern Philippines, is often framed as a Muslim-Christian conflict and reinterpreted as such within the US-led global war on terror, with the Muslim secessionist movement standing accused of providing a hub for international jihad. In the meantime, global economic integration has made it easier to ignore the agrarian roots of violent conflict in Mindanao, enabling national and sub-national actors, including…
