Toward Sustainable Agricultural Systems in the 21st Century

In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental,...

Insect Herbivore-Host Dynamics

Literature on the population dynamics of insect herbivores tends to favour a top-down regulation of abundance, owing much to the action of natural enemies. Originally published in 2005, this volume challenges this paradigm and argues that tree-dwelling species of aphids, through competition for resources, regulate their own abundance. The biology of tree-dwelling aphids is examined, particularly their adaptation to the seasonal development of their host plants. When host-plant quality is favourable, aphids, by telescoping generations, can achieve prodigious rates of increase which their natural enemies are unable to match. Using analyses of long-term population censuses and results of experiments, this book introduces students and research workers to insect herbivore-host dynamics using the interaction between aphids and trees as a model.

Emerging Technologies to Benefit Farmers in Sub-Saharan Africa and South Asia

Increased agricultural productivity is a major stepping stone on the path out of poverty in sub-Saharan Africa and South Asia, but farmers there face tremendous challenges improving production. Poor soil, inefficient water use, and a lack of access to plant breeding resources, nutritious animal feed, high quality seed, and fuel and electricity-combined with some of the most extreme environmental conditions on Earth-have made yields in crop and animal production far lower in these regions than world averages. Emerging Technologies to Benefit Farmers in Sub-Saharan Africa and South Asia identifies sixty emerging technologies with the potential to significantly improve agricultural productivity in sub-Saharan Africa and South Asia. Eighteen technologies are recommended for immediate development or further exploration. Scientists from all backgrounds have an opportunity to become involved in bringing these and other technologies to fruition. The opportunities suggested in this book offer new approaches that can synergize with each other and with many other activities to transform agriculture in sub-Saharan Africa and South Asia.

Education as the Practice of Eco-Social-Cultural Change

The current ecological crisis is the consequence of entrenched attitudes, discourses and behaviours in human societies worldwide, fostered and reinforced through modern educational traditions, processes and institutions. This book envisions a radical transformation of education to focus on the mutual flourishing of human societies with the rest of life on Earth. In part, the authors suggest approaching this as a problem of systemic design, incorporating principles that challenge and undermine key premises of the Capitalocene—the socio-economic-political landscape sustaining the current educational regime. Tracing the implications of this transition, they review core assumptions of modern Western culture that need to shift, and identify a wide range of relevant capacities and practices grouped under four complementary educator “stances” for eco-social-cultural change.
