Risk and sustainable crop intensification by Van Campenhout, Bjorn,Bizimungu, Emmanuel,Birungi, Dorothy Pdf

To feed a growing and increasingly urbanized population, Uganda needs to increase crop production without further exhausting available resources. Therefore, smallholder farmers are encouraged to adopt sustainable crop intensification methods such as inorganic fertilizer or hybrid seeds. However, these farmers perceive these new technologies as risky hence adoption will depend on how well they can manage this additional risk. This paper documents patterns observed in socioeconomic data that suggest risk is an important barrier to sustainable crop intensification practices among Ugandan smallholder rice and potato farmers. In particular, we find that households that engage in risk management strategies, such as investing in risk-reducing technology or engaging in precautionary savings, are more likely to practice intensified cropping. However, our data also show only limited yield risk associated with the use of fertilizers or pesticides, suggesting part of the problem is related to perception. We also discuss the consequences for policy.

Risk and sustainable crop intensification among Ugandan rice and potato farmers by Van Campenhout, Bjorn,Bizimungu, Emmanuel,Birungi Namuyiga, Dorothy Pdf

To feed a growing and increasingly urbanized population, Uganda needs to increase crop production without further exhausting available resources. Therefore, smallholder farmers are encouraged to adopt sustainable crop intensification methods such as inorganic fertilizer or hybrid seeds. However, as farmers perceive these new technologies as risky, adoption will depend on how well they can manage this additional risk. This brief documents patterns observed in socioeconomic data that suggest risk is indeed an important barrier to sustainable crop intensification practices among Ugandan smallholder rice and potato farmers. In particular, we find that households that engage in risk management strategies, such as investing in risk-reducing technology or engaging in precautionary savings, are more likely to practice intensified cropping. However, our data also show only limited downside yield risk associated with the use of fertilizers or pesticides, suggesting part of the problem is related to perception. We conclude with some policy options derived from these findings.

Sustainable Intensification of Crop Production by P. Parvatha Reddy Pdf

This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.

Mitigating health risks in sustainable agricultural intensification by Lines, Jo,Bett, Bernard,Fèvre, Eric,Moodley, Arshnee,Waage, Jeff Pdf

Human health is a fundamental feature of sustainable agricultural intensification. Agricultural intensification that increases the burden of human disease, however environmentally benign, is not sustainable. Conversely, sustainable agricultural methods provide specific opportunities for improving human health. The intensification of food systems in low- and middle income countries (LMIC), as they transition from subsistence to market-oriented production, is typically associated with human health risks. Some health risks are associated with the initial stages of intensification, for example, concentration of livestock production and animal waste in peri-urban areas. Inputs associated with this intensification, including fertilizers, pesticides, and antibiotics, can have negative effects on farmers’ health, clean water, and resistance in pathogens and vectors. In rapidly intensifying agricultural systems, regulatory processes that limit the use of harmful products and their residues in water and food may not be in place. Therefore, LMIC face a particular challenge to “de-risk” agricultural intensification, through technicaland policy-related interventions that reduce health risks in transitioning agricultural systems.

Sustainable Intensification by Jules N. Pretty,Stella Williams,Camilla Toulmin Pdf

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Methods for Measuring Greenhouse Gas Balances and Evaluating Mitigation Options in Smallholder Agriculture by Todd S. Rosenstock,Mariana C. Rufino,Klaus Butterbach-Bahl,Lini Wollenberg,Meryl Richards Pdf

​​This book provides standards and guidelines for quantifying greenhouse gas emissions and removals in smallholder agricultural systems and comparing options for climate change mitigation based on emission reductions and livelihood trade-offs. Globally, agriculture is directly responsible for about 11% of annual greenhouse gas (GHG) emissions and induces an additional 17% through land use change, mostly in developing countries. Farms in the developing countries of sub-Saharan Africa and Asia are predominately managed by smallholders, with 80% of land holdings smaller than ten hectares. However, little to no information exists on greenhouse gas emissions and mitigation potentials in smallholder agriculture. Greenhouse gas measurements in agriculture are expensive, time consuming, and error prone, challenges only exacerbated by the heterogeneity of smallholder systems and landscapes. Concerns over methodological rigor, measurement costs, and the diversity of approaches, coupled with the demand for robust information suggest it is germane for the scientific community to establish standards of measurements for quantifying GHG emissions from smallholder agriculture. Standard guidelines for use by scientists, development organizations will help generate reliable data on emissions baselines and allow rigorous comparisons of mitigation options. The guidelines described in this book, developed by the CGIAR Research Program on Climate Change, Agriculture, and Food Security (CCAFS) and partners, are intended to inform anyone conducting field measurements of agricultural greenhouse gas sources and sinks, especially to develop IPCC Tier 2 emission factors or to compare mitigation options in smallholder systems.

Sustainable Intensification of Agriculture by Jules Pretty,Zareen Pervez Bharucha Pdf

Sustainable intensification (SI) has emerged in recent years as a powerful new conceptualisation of agricultural sustainability and has been widely adopted in policy circles and debates. It is defined as a process or system where yields are increased without adverse environmental impact and without the cultivation of more land. Co-written by Jules Pretty, one of the pioneers of the concept and internationally known and respected authority on sustainable agriculture, this book sets out current thinking and debates around sustainable agriculture and intensification. It recognises that world population is increasing rapidly, so that yields must increase on finite land and other resources to maintain food security. It provides the first widely accessible overview of the concept of SI as an innovative approach to agriculture and as a key element in the transition to a green economy. It presents evidence from around the world to show how various innovations are improving yields, resilience and farm incomes, particularly for ‘resource constrained’ smallholders in developing countries, but also in the developed world. It shows how SI is a fundamental departure from previous models of agricultural intensification. It also highlights the particular role and potential of small-scale farmers and the fundamental importance of social and human capital in designing and spreading effective innovations.

Save and Grow by Mangala Rai,Timothy G. Reeves,Shivaji Pandey,Linda Collette Pdf

In many countries, decades of intensive cropping have degraded fertile land and depleted groundwater, provoked pest upsurges, eroded biodiversity, and polluted air, soil and water. The present paradigm of intensive crop production cannot meet the challenges of the new millennium. In order to grow, agriculture must learn to save. This book presents a new paradigm: sustainable crop production intensification (SCPI), which produces more from the same area of land while conserving resources, reducing negative impacts on the environment and enhancing natural capital and the flow of ecosystem services. Also published in Arabic, Chinese, French, Russian and Spanish.

Crop Protection and Sustainable Agriculture by Derek J. Chadwick,Joan Marsh Pdf

The increase in the world population and changes in welfare have led to an enormously expanding demand for food. In the industrialized world, food surpluses rather than shortages are a problem together with adverse environmental impacts from the overuse of chemicals and excessive exploitation of agricultural land. In the developing world, food production cannot keep up with population growth and the gap between demand and supply is growing. This book explores the theme of sustainable agricultural development in the developing world, with a particular focus on crop protection. Includes chapters on the ecology of food production, on sustainable agriculture and crop protection methods, on the economics of food production and more.

Sustainable Intensification for Agroecosystem Services and Management by Manoj Kumar Jhariya,Arnab Banerjee,Ram Swaroop Meena,Sandeep Kumar,Abhishek Raj Pdf

This edited book provides a comprehensive account of the sustainable intensification process through various forms of case studies and scientific approaches studied across the globe. It also focuses on the agroecosystem services and their subsequent management for ecological integrity. The book helps to understand the interconnection of food, nutrition, economic growth, and environmental security on the planet. It provides comprehensive information with photographic illustration and various other forms of scientific databases on sustainable intensification of agroecosystems. The book also supports decision-making, strategies, and policy formulation for effective implementation of sustainable intensification towards higher productivity along with maintenance and management of agroecosystem services. Proper sustainable intensification of agroecosystem services and their management by maintaining ecological harmony is the future prospect for sustainable development. High input agriculture gives rise to a high-energy footprint, agricultural pollution, resource depletion, loss of agro-biodiversity, and decline of human health. Through this connection, the sustainable intensification approach addresses the advanced food security, sustainability, and overall prosperity of humankind. The book is helpful for both undergraduate and postgraduate students, policymakers, the farming community, as well as the scientific community across the globe to understand the concept of sustainable intensification and its application in relevant fields for proper management of agroecosystems services.

Stimulating agricultural technology adoption: Lessons from fertilizer use among Ugandan potato farmers by Nazziwa-Nviiri, Lydia,Van Campenhout, Bjorn,Amwonya, David Pdf

In the context of a growing population in an already densely populated area, agricultural yields will need to increase without putting additional stress on the environment. The adoption of modern inputs by smallholders is an important ingredient of agricultural transformation. In this study we explore plot-level, household-level, and institutional-level characteristics associated with agricultural technology adoption behavior among smallholder farmers. The aim is to uncover correlations that can guide the design of policies and incentives that are likely to increase adoption. We explicitly differentiate between fixed costs that are likely to affect the decision to use the technology and variable costs that are more relevant for the decision regarding use intensity. In addition, we examine how the importance of each of these characteristics differs with asset status. To do so, we use data from about 1,880 potato plots cultivated by 500 randomly selected potato growers in southwestern Uganda. We first categorize households into poorly endowed and well-endowed asset classes based on their access to productive assets. We then estimate double-hurdle models for take-up and use intensity of fertilizer for each group. The results show that the factors associated with the decision to use fertilizer are often different from those associated with the decision about how much fertilizer to use and that the characteristics correlated with fertilizer adoption differ between asset-poor and asset-rich farmers. For instance, asset-poor female-headed households are less likely to use fertilizer, but if they do, they use more of it than male-headed households. Our results also suggest fertilizer packaging and distribution are important factors in fertilizer adoption decisions due to their impact on costs related to both indivisibilities and uncertainty about the quality. We derive a range of policy recommendations.
