A key challenge in systematically collecting data on intermediary agri-food value chain actors is that value chains take the form of a network, with actors linked by a series of transactions. Moreover, we have limited ex ante knowledge about the structure or scale of these networks, which complicates the construction of valid sampling frames and limits traditional random sampling approaches to collect data. To address these challenges, we adapt the respondent-driven sampling approach to collect data on intermediary agri-food value chain actors within their transaction-linked network and implement this approach in the arabica coffee and soybean value chains in Uganda and the rice and potato value chains in Bangladesh. We observe meaningful heterogeneity in the structure and scale of agri-food value chains across commodities and countries. Focusing on traders, we show that the respondent-driven sampling approach generates a larger sample of traders who differ in observable characteristics (i.e., value added, enterprise scale, and financial access) compared to a sub-sample of traders generated in a way that mimics traditional random sampling approaches used to study traders. We conclude by discussing how this respondent-driven sampling approach, applied within transaction-linked networks, can provide a useful data collection method for studying intermediary agri-food value chain actors.

Debates about public expenditure in the agricultural sector have reopened in many developing and emerging economies because of high budget deficits and changes in public opinion. As a result, agricultural policy in many of these countries is beginning to take a more market-oriented approach to agrarian problems, most notably through the introduction of contract farming. This book explores the policy issues around contract farming and its transformative potential and addresses the lack of empirical research on this topic by focusing on South Asia: principally India, Bangladesh and Nepal. The book first addresses the effects of contract farming (vertical coordination) on productivity, food security indicators (yield, consumption expenditures, prices), employment and input usage. Then it draws lessons from the South Asian case studies on the impact of institutional changes, like contract farming, on income and food security of smallholder households. The core of the book includes case study chapters on several commodities that are produced under contract farming, including vegetables and fisheries in Bangladesh, low-value crops in Nepal and coffee in India. Other chapters also explore contracts, storage, input usage and technical efficiency in these cases. This book serves as an essential guide to academics, researchers, students, legislative liaisons and think tank groups interested in agrarian issues, agricultural economics and agricultural policy in emerging economies and particularly in South Asia.

It is widely agreed that, over the past decade, accelerating infrastructure investments in India's North Eastern Region (NER) and neighboring countries, along with connectivity agreements with Bangladesh, hold immense promise for unlocking NER's economic potential. Other global trends, such as the growing incomes and consumer awareness in India and neighboring countries; a rising preference for fresh, healthy, safe, environmentally friendly, and socially responsible products; the growing role of services in manufacturing; and increasing demand for skilled resources are also very favorable for NER. Together, these developments can help NER showcase its strengths in agriculture and services, thereby developing value chains in these sectors, which will lead to sustainable, better-paying job opportunities for the people of NER. In this context, the World Bank, in consultation with stakeholders--government, private sector, and academia--analyzed two cross-cutting constraints that are encountered across all value chains and sectors in NER: connectivity and logistics, and product standards and quality infrastructure. To ground the policy in specific contexts, the team studied four sectors in depth: fruits and vegetables, spices, bamboo and related products, and medical tourism. Playing to Strengths lays out an initial policy framework for NER that integrates demand and supply and shows that, even with a low base in manufacturing, NER can leverage its strengths in agriculture and services to step up its growth. However, implementing this framework will require a different approach to doing business compared with the existing ecosystem and its associated value chains, which are mostly geared to local and/or price-conscious consumers. In capitalizing on its advantages, NER will not only accelerate its own development, but also will play an increasingly critical role in the government of India's "Act East" policy.
