Is Environmentally Friendly Agriculture Less Profitable For Farmers

"Concerns about the sustainability of conventional agriculture have prompted widespread introduction of integrated pest management (IPM), an ecologically-based approach to control of harmful insects and weeds. IPM is intended to reduce ecological and health damage from chemical pesticides by using natural parasites and predators to control pest populations. Since chemical pesticides are expensive for poor farmers, IPM offers the prospect of lower production costs and higher profitability. However, adoption of IPM may reduce profitability if it also lowers overall productivity, or induces more intensive use of other production factors. On the other hand, IPM may actually promote more productive farming by encouraging more skillful use of available resources. Data scarcity has hindered a full accounting of IPM's impact on profitability, health, and local ecosystems.

Using new survey data, the authors attempt such an accounting for rice farmers in Bangladesh. They compare outcomes for farming with IPM and conventional techniques, using input-use accounting, conventional production functions, and frontier production estimation. All of their results suggest that the productivity of IPM rice farming is not significantly different from the productivity of conventional farming. Since IPM reduces pesticide costs with no countervailing loss in production, it appears to be more profitable than conventional rice farming. The interview results also suggest substantial health and ecological benefits. However, externality problems make it difficult for farmers to adopt IPM individually. Without collective adoption, neighbors' continued reliance on chemicals to kill pests will also kill helpful parasites and predators, as well as exposing IPM farmers and local ecosystems to chemical spillovers from adjoining fields. Successful IPM adoption may therefore depend on institutional support for collective action.

Sustainable agricultural practices enable more efficient use of natural resources, mitigate the impact of agriculture on the environment, and strengthen capacity for adaptation to climate change and climate variability. Because these practices usually require substantial effort or resource allocation from farmers, incentives are necessary to support farmer adoption. Despite growing interest, there has been little systematic evaluation of the incentives–adoption–outcome chain—that is, which incentives best promote adoption and which lead to desired sustainability outcomes. This brief presents the results of a literature review that examined (1) uptake agricultural practices under three kinds of incentives, market and nonmarket, regulations, and cross-compliance, and (2) the impact on productivity, profitability, and environmental sustainability. Based on this review, it offers a set of seven tested principles to follow in designing and implementing incentives for sustainable agriculture.

This study reviews the available information on the contribution of biodiversity for food and agriculture to the resilience of crop, livestock, forest, fishery and aquaculture production systems to environmental change and uncertainty.

The Earth's biodiversity-the rich variety of life on our planet-is disappearing at an alarming rate. And while many books have focused on the expected ecological consequences, or on the aesthetic, ethical, sociological, or economic dimensions of this loss, Sustaining Life is the first book to examine the full range of potential threats that diminishing biodiversity poses to human health. Edited and written by Harvard Medical School physicians Eric Chivian and Aaron Bernstein, along with more than 100 leading scientists who contributed to writing and reviewing the book, Sustaining Life presents a comprehensive--and sobering--view of how human medicines, biomedical research, the emergence and spread of infectious diseases, and the production of food, both on land and in the oceans, depend on biodiversity. The book's ten chapters cover everything from what biodiversity is and how human activity threatens it to how we as individuals can help conserve the world's richly varied biota. Seven groups of organisms, some of the most endangered on Earth, provide detailed case studies to illustrate the contributions they have already made to human medicine, and those they are expected to make if we do not drive them to extinction. Drawing on the latest research, but written in language a general reader can easily follow, Sustaining Life argues that we can no longer see ourselves as separate from the natural world, nor assume that we will not be harmed by its alteration. Our health, as the authors so vividly show, depends on the health of other species and on the vitality of natural ecosystems. With a foreword by E.O. Wilson and a prologue by Kofi Annan, and more than 200 poignant color illustrations, Sustaining Life contributes essential perspective to the debate over how humans affect biodiversity and a compelling demonstration of the human health costs.

With all of the environmental and social problems confronting our food systems today, it is apparent that none of the strategies we have relied on in the pasthigher-yielding varieties, increased irrigation, inorganic fertilizers, pest damage reductioncan be counted on to come to the rescue. In fact, these solutions are now part of the problem. It i
