In recent years there has been a movement on the part of farmers, governments, Non-Governmental Organizations (NGO), and the international community to promote the use of sustainable agricultural practices. In Sub-Saharan Africa, this has translated into programs with the expressed aim of increasing smallholder farmer adoption rates of conservation agriculture (CA). This thesis contributes to the analysis of the adoption of conservation agriculture by smallholder farmers in Sub-Saharan Africa by assessing the economic status of CA adopters in the providences of Manica and Tete, Mozambique. Chapter II of the thesis examines the ceteris paribus correlation between smallholder farm household economic wellbeing with the use of conservation agriculture. Household wellbeing indicators are regressed on household demographic attributes, farm management practices, and a variable indicating the CA adoption status of farms. Of particular interest is the association between the use of conservation agriculture practices and a set of composite wellbeing indices comprised of livestock and asset ownership, and housing material quality. The results suggest that, holding other factors constant, CA households have higher wellbeing index scores related to asset ownership and housing material quality, but lower index scores related to livestock ownership. Chapter III of the thesis analyzes smallholder marketing of maize and use of CA by farmers. The chapter examines the factors associated with the likelihood of a household participating in maize markets as a vendor or buyer, and the subsequent quantity of maize transacted. A censored regression model estimates the intensity of market participation because a large number of households do not buy or sell grain. Of particular interest is the correlation between the adoption of CA practices and the likelihood a household sold or purchased maize. Results suggest that households using CA were more likely to sell maize and less likely to purchase maize for household consumption. However, the overall quantities sold by CA adopters and non-adopters were not different. Households using CA also exhibited different maize marketing patterns with transactions more evenly distributed throughout the year, as compared to non-CA households whose transactions were concentrated during times when food was scarce.
The book covers the spread of conservation agriculture (CA) to regions including Brazil, Argentina, Canada, Australia, Europe and emerging CA destinations in Asia and Africa. ÿTopics covered include the various components of CA, and how their individual and combined implementation influence productivity, soil health and environmental quality under diverse edaphic and climatic conditions. The book will be useful to teachers, researchers, extensionists, farmers, and students interested in environmental quality.
This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.
This is an eloquent, engaged and extremely well informed narrative of the environmental and natural resource conservation and management issues in Mozambique. While the topics in this volume are diverse, they are all explicitly designed to move beyond the routinized blame of natural resource mismanagement and environmental degradation on local communities, and to rethink ecosystem destruction, land degradation and natural resource over-exploitation in Africa and beyond. Never losing sight of the major causes of environment and resource mismanagement in Mozambique, the book advances the thesis that environment and resource problems are a result of compound factors such as poor governance, poverty, corruption, low education levels, and disregard of endogenous conservation epistemologies. A combination of all these factors makes the whole terrain of conservation even more complicated than ever; hence the need for urgent action by all social actors. This is a valuable book for environmental conservationists, land resource managers, social ecologists, environmental anthropologists, environmental field workers and technicians, practitioners and students of conservation sciences.
Tillage agriculture has led to widespread soil and ecosystem degradation globally, and more particularly in the developing regions. This is especially so in Africa where traditional agricultural practices have become unsustainable due to severe exploitation of natural resources with negative impacts on the environment and food system. In addition, agricultural land use in Africa today faces major challenges including increased costs, climate change and a need to transform to more sustainable production intensification systems. Conservation Agriculture has emerged as a major alternative sustainable climate smart agriculture approach in Africa and has spread to many African countries in the past decade as more development and research, including in sustainable mechanization, has enabled its extension and uptake. It is key to transforming Africa's agriculture and food system given its ability to restore soil health, biodiversity and productivity of millions of smallholder farms as well as larger-scale farms. This book is aimed at all agricultural stakeholders in the public, private and civil sectors in Africa engaged in supporting the transformation of conventional tillage agriculture to Conservation Agriculture. The book will be of interest to: researchers, academics, students, development stakeholders, public and private sector investors and policy makers as well as institutional libraries across the world.
