Although a large theoretical literature discusses the possible inefficiency of sharecropping contracts, the empirical evidence on this phenomenon has been ambiguous at best. Household-level fixed-effect estimates from about 8,500 plots operated by households that own and sharecrop land in the Ethiopian highlands provide support for the hypothesis of Marshallian inefficiency.

Our analysis points towards factor market imperfections (no rental for oxen), lack of alternative employment opportunities, and tenure insecurity as possible reasons underlying such behavior, suggesting that, rather than worrying almost exclusively about Marshallian inefficiency, it is equally warranted to give due attention to the policy framework within which land rental markets operate.

This book is the first systematic attempt to address emerging land markets and their implications for poverty, equity, and efficiency across a number of African countries. The high incidence of poverty and the need for increased agricultural productivity remain acute in rural areas of sub-Saharan Africa, where a lack of secure land rights and a growing scarcity of land relative to the size of the population are becoming increasingly critical issues. Indeed, land issues in the region are high on the international policy agenda. Yet our knowledge about land tenure security and other rural factor markets (such as labor, oxen, manure, purchased inputs, and credit) is far from adequate to formulate sensible policies. The case studies in the book show that, while land markets and especially informal markets have been rapidly emerging in densely populated parts of Africa - and have generally been to the benefit of the poor--their functions remain imperfect. This is due to policy-induced tenure insecurity and the fragmentation of agricultural land. Applying rigorous quantitative analyses, the book provides a basis for taking into account the role of land markets in national land policies. All too often, the authors argue, land policies have been extreme, either prohibiting all land transactions or giving unrestricted freehold rights to a small elite at the expense of the poor. From the long experience in Asia, it is known that such policies are detrimental to both production efficiency and equity of land use. The authors argue that future policies in Africa should work with the markets. Regulations should be imposed only with careful testing that they are having the intended effects. The Emergence of Land Markets in Africa is a resource for teaching in developed and developing countries, as it provides both comprehensive reviews of the literature and detailed case studies. It is intended to facilitate the dialogue between researchers and policymakers, as well as inspire researchers to go further in their investigations and build an even stronger basis for good policies. The Emergence of Land Markets in Africa is the first publication in the new Environment for Development (EfD) book series. EfD books focus on research and applications in environmental and natural resource economics as they are relevant to poverty reduction and environmental problems in developing countries. The EfD book series is part of the EfD initiative. (www.environmentfordevelopment.org)

Highland Ethiopia is one of the most densely populated regions of Africa and has long been associated with both Malthusian disasters and Boserupian agricultural intensification. This paper explores the race between these two countervailing forces, with the goal of informing two important policy questions. First, how do rural Ethiopians adapt to land constraints? And second, do land constraints significantly influence welfare outcomes in rural Ethiopia? To answer these questions we use a recent household survey of high-potential areas. We first show that farm sizes are generally very small in the Ethiopian highlands and declining over time, with young rural households facing particularly severe land constraints. We then ask whether smaller and declining farm sizes are inducing agricultural intensification, and if so, how. We find strong evidence in favor of the Boserupian hypothesis that land-constrained villages typically use significantly more purchased input costs per hectare and more family labor, and achieve higher maize and teff yields and high gross income per hectare. However, although these higher inputs raise gross revenue, we find no substantial impact of greater land constraints on net farm income per hectare once family labor costs are accounted for. Moreover, farm sizes are strongly positively correlated with net farm income, suggesting that land constraints are an important cause of rural poverty. We conclude with some broad policy implications of our results.

This handbook initiates fresh debates on poverty and its impact in a constantly changing Global South society. It studies the concept, theories, and causes of poverty, as well as the design and delivery of social welfare policies related to specific groups, such as women, children, and the elderly. The chapters are theoretical, evidence-based, and empirical in nature and bring together a holistic understanding of social problems and issues in developing countries. The volume brings together researchers, educators, and practitioners from across the globe to develop a hands-on reference work that will be requisite for several social science disciplines concerned with poverty and the welfare of poor people. The first of its kind, the handbook will be indispensable for scholars and researchers of development studies, economics, social work, political studies, poverty studies, population and demographic studies, sociology, social anthropology, public policy, and political economy, especially those concerned with the Global South.

Rural poverty remains widespread and persistent in South Asia and Sub-Saharan Africa. A group of leading experts critically examines the impact of land tenure reforms on poverty reduction and natural resource management in countries in Africa and Asia with highly diverse historical contexts.

The sign that ‘Africa is on Sale’ has been appearing with regular frequency in major newspaper accounts across the world, indicating that large amounts/expanses of Africa’s rich farmlands are being sold to transnational investors, usually on long-term leases, at a rate not seen in decades – indeed not since the colonial period. Transnational and national economic actors from various business sectors (oil and auto, mining and forestry, food and chemical, bioenergy, etc.) are eagerly acquiring, or declaring their intention to acquire large areas of land on which to build, maintain or extend large-scale extractive and agro-industrial enterprises to help secure their own food and energy needs into the future. This book provides a critical appraisal of the growing phenomenon of land grabbing in Africa. Far from being a technical issue associated "good governance", the problem of land grabbing by transnational corporation and states is a serious threat for the food security of millions of Africans and is undoubtedly one of the great challenges of our time for development on the continent. The case studies illustrate that African states are also complicit in the massive land grabbing by actively participating in isolated development while excluding the local communities. The case studies reveal key features that characterize how the global land grab plays out in specific localities in Africa. This book was published as a special issue of African Identities.
