  2. Agricultural biodiversity - Wikipedia

    en.wikipedia.org/wiki/Agricultural_biodiversity

    Agricultural biodiversity or agrobiodiversity is a subset of general biodiversity pertaining to agriculture. It can be defined as "the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and ...

    Agriculture in Van Zandt County, Texas in 1904 Early Czechoslovakian and German immigrants arrived in the region around 1825 to 1845 and found the rich black soil excellent for farming. By the end of the 19th century 98% of the blackland prairies were cultivated and it was the leading cotton region of the state, also producing sorghum, corn ...

    The environmental impact of agriculture involves impacts on a variety of different factors: the soil, water, the air, animal and soil variety, people, plants, and the food itself. Agriculture contributes to a number larger of environmental issues that cause environmental degradation including: climate change, deforestation, biodiversity loss ...

  5. Tallgrass prairie - Wikipedia

    en.wikipedia.org/wiki/Tallgrass_prairie

    Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.

  6. Biodiversity in agriculture - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_in_agriculture

    Biodiversity is the measure of biotic and abiotic diversity in an ecosystem, described by heterogeneity. [1] The loss of biodiversity in agriculture has been an increasing issue since the global increase of food demands and success of popular crops. [3] [4] This loss of heterogeneity declines species biodiversity on agricultural lands. [5]

  7. Organic farming and biodiversity - Wikipedia

    en.wikipedia.org/wiki/Organic_farming_and...

    Organic farming and biodiversity. The effect of organic farming has been a subject of interest for researchers. Theory suggests that organic farming practices, which exclude the use of most synthetic pesticides and fertilizers, may be beneficial for biodiversity. This is generally shown to be true for soils scaled to the area of cultivated land ...

  8. Crop diversity - Wikipedia

    en.wikipedia.org/wiki/Crop_diversity

    Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity. Over the past 50 years, there has been a major decline in two components of crop diversity; genetic diversity within ...

  9. Ecological effects of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Ecological_effects_of...

    The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
