"Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics."
The study of the importance of planting a diversity of crops to enhance soil fertility and prevent disease and pest outbreaks.
Crop rotations: The practice of planting different crops in a particular sequence on the same field every year to improve soil health and reduce disease.
Cover crops: Plants grown specifically to improve soil quality, reduce erosion, prevent weeds, and provide habitat for beneficial insects.
Intercroping: Growing two or more crops in close proximity on the same field to increase yields and improve pest control.
Polyculture: The practice of growing multiple crops in the same area in a way that mimics natural ecosystems and utilizes their benefits.
Organic farming: A method of farming that avoids synthetic pesticides and fertilizers, genetically modified organisms (GMOs), and focuses on soil health and biodiversity.
Agroforestry: Combining agriculture and forestry methods in a way that maximizes productivity and improves biodiversity.
Heirloom and heritage seeds: Seeds from older varieties of crops that are traditionally grown and are often more genetically diverse and adaptable to local conditions.
Landraces: Locally adapted crops that have been cultivated and selected by traditional farmers over many generations.
Wild relatives of crops: Plants that are closely related to cultivated crops and can be used to breed new varieties with improved traits like disease resistance.
Plant breeding: Improving crop varieties through traditional breeding methods or genetic engineering to enhance productivity, quality, and sustainability.
Seed banks: Collections of seeds that are conserved and preserved for future use in plant breeding, research, or emergency situations.
Climate-smart agriculture: Agricultural practices that are adapted to the changing climate and aim to reduce greenhouse gas emissions, increase carbon sequestration, and improve resilience.
Indigenous knowledge: Traditional knowledge and practices of indigenous communities that are often based on the sustainable use and management of natural resources.
Market opportunities for diverse crops: Identifying and creating market demand for diverse crops that are often not mainstream but can provide economic benefits to farmers.
Policy frameworks: National and international policies and regulations that promote crop diversity and sustainable agriculture practices.
Genetic diversity: This denotes the variety of genes within a crop species.
Intraspecific diversity: This refers to the diversity within a single crop species that possesses variations in crop physiology, morphology, or other characteristics.
Interspecific diversity: This is the diversity among various crop species; it happens when different plant species are cultivated in a given agricultural setting.
Inter-cropping: Two or more crop species that are grown together in the same field or area at the same time.
Crop rotation: This is the practice of planting different crops in a particular sequence over the years in the same field, allowing the soil to regain nutrients and organic matter.
Traditional varieties: These are the crop varieties that have been cultivated and passed down over generations by farmers.
Heirloom varieties: Crop varieties that have been preserved for their unique taste, color, and texture by a particular community, and are often grown in small quantities.
Hybridization: This is the process of breeding two similar crop varieties to produce a new crop that exhibits desired traits from both.
GMOs: Also known as genetically modified organisms, crops created through genetic engineering techniques to produce crops with desirable traits.
Tissue culture: Crop propagation technique used in greenhouses under sterile, laboratory conditions to produce exact genetic copies of a parent plant.
Multi-cropping: This is the practice of growing multiple crops at the same time, in a manner that allows for multiple harvests in a single year.
Cover crops: Crops that are planted specifically to cover the soil and reduce soil erosion, while also improving soil quality.
Companion planting: Planting different plant species together to create mutually beneficial relationships between them, such as repelling insects and improving soil quality.
Soil microbiome: The diversity of living organisms within the soil that supports crop growth, increase the soil nutrients, main soil structure, and prevent soil erosion.
Gender-sensitive diversity: This is the practice of selecting crops that are adapted to the specific needs of women farmers, helping to improve their productivity, and also supporting gender equity.
"There has been a major decline in two components of crop diversity; genetic diversity within each crop and the number of species commonly grown."
"Crop diversity loss threatens global food security, as the world's human population depends on a diminishing number of varieties of a diminishing number of crop species."
"Crops are increasingly grown in monoculture, meaning that if, as in the historic Great Famine of Ireland, a single disease overcomes a variety's resistance, it may destroy an entire harvest, or as in the case of the 'Gros Michel' banana, may cause the commercial extinction of an entire variety."

"With the help of seed banks, international organizations are working to preserve crop diversity."
"It is a subset of and a specific element of agricultural biodiversity."
"Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics."
"There has been a major decline in genetic diversity within each crop, which is crucial for maintaining healthy and resilient crops."
"Decreased genetic diversity within crops can make them more susceptible to diseases and environmental changes."
"The number of species commonly grown has also declined, leading to a reduction in overall crop diversity."
"The world's human population depends on a diminishing number of varieties of a diminishing number of crop species."
"If a single disease overcomes a variety's resistance, it may destroy an entire harvest."
"The 'Gros Michel' banana is an example where monoculture caused the commercial extinction of an entire variety."
"It is crucial to preserve crop diversity to ensure global food security and avoid dependency on a limited number of crop varieties."
"International organizations are working to preserve crop diversity, often through initiatives such as seed banks."
"Crop diversity includes the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics."
"Relying on a diminishing number of crop varieties increases the vulnerability of the food system to potential catastrophes."
"Crop monoculture poses risks such as vulnerability to diseases, pests, and the loss of biodiversity necessary for resilient agricultural systems."
