Conserving Biological Diversity in Agricultural/Forestry Systems

1992
Organizations/Sources: BioScience
Both high agricultural productivity and human health depend on the activity of a diverse natural biota and although efforts to curb the loss of biodiversity have intensified in recent years, they have not kept pace with the growing encroachment of human activities. An example of the economic benefits described is, $20 billion year spent worldwide on pesticides, but parasites and predators existing in natural ecosystems provide an estimated five to ten times this amount of the pest control, and without the existence of natural enemies, crop losses by pests in agriculture and forestry would be catastrophic and costs of chemical pest controls would escalate enormously.

Economic and Environmental Benefits of Biodiversity

1997
Organizations/Sources: BioScience
Maintaining biodiversity is essential for organic waste disposal, soil formation, biological nitrogen fixation, crop and livestock genetics, biological pest control, plant pollination, and pharmaceutical development. The authors estimate that in the United States, biodiversity provides a total of $319 billion dollars in annual benefits and $2,928 billion in annual benefits worldwide. The paper describes many of the individual factors that went into calculating this number.

Economic Reasons for Conserving Wild Nature

2002
Organizations/Sources: Science Magazine
Amidst continuing loss of natural habitat and biodiversity, it is necessary to examine the benefit:cost ratio of investments in habitat conservation. Evidence has been accumulating that shows habitat conservation generates more economic benefits than does habitat conversion. The authors estimate that the overall benefit:cost ratio of an effective global program for the conservation of remaining wild nature is at least 100:1.

Impacts of Biodiversity on the Emergence and Transmission of Infectious Diseases

2010
Authors: Felicia Keesing
Organizations/Sources: Nature
A loss of biodiversity leads to an increase in the spread of disease, which researchers speculate is because some species are better at buffering disease transmission. The study examines 12 diseases from different ecosystems worldwide, including Lyme disease. In eastern North America, the white-footed mouse, which is abundant in low-diversity forest fragments is associated with high levels of lyme disease transmission, while Virginia opossums, which are absent from many low-diversity forest fragments and degraded forests, are poor hosts for the pathogen and kill the vast majority the ticks which spread the disease that attempt to feed on them.

Linking Biodiversity Conservation and Poverty Alleviation: A State of Knowledge Review

2010
Organizations/Sources: Convention on Biological Diversity
Biodiversity conservation and poverty reduction are two global challenges that are inextricably linked, but because biodiversity is generally a public good, it is under-valued, or not valued at all, in national economies. This paper focuses on the question “which groups of the (differentiated) poor depend, in which types of ways, on different elements of biological diversity?” It focuses on biodiversity as a means of subsistence and income to the poor and biodiversity as insurance to prevent the poor from falling even deeper into poverty.

Pennsylvania State Fish Hatcheries: Engines for Rural Economic Development

Organizations/Sources: Pennsylvania Fish & Boat Commission
There are 15 state fish hatcheries in Pennsylvania. Owned by the state and operated by the Fish and Boat Commission, these hatcheries are strategically located across the Commonwealth to take advantage of high-quality water supplies and to maximize fish stocking logistics. Pennsylvania's state fish hatcheries are engines for economic development. Eight hatcheries combine to produce some 4 million adult trout annually. Stocked into the waters of the Commonwealth, these trout support fishing activity that generates some $500 million in economic activity each year.
