Neglected and underutilized crop

Last updated

Neglected and under-utilised crops are domesticated plant species used for food, medicine, trading, or cultural practices significant within their local communities but not widely commodified or studied as part of mainstream agriculture. [1] [2] Such crops may be in declining production. [3] They are considered under-utilised in scientific inquiry for their perceived potential to contribute to knowledge regarding nutrition, food security, genetic resistance, or sustainability. [4] Other terms to describe such crops include minor, orphan, underused, local, traditional, alternative, minor, niche, or underdeveloped. [5]

Three crops, maize, wheat, and rice, account for approximately 50% of the world's consumption of calories and protein, [6] and about 95% of the world's food needs are provided by just 30 species of plants. [7] Despite this, the list of crop species compiled as edible extends to around 12,650. [8] Among these are neglected and under-utilised plants that in many cases have been used for food and other uses on a larger scale historically.

Reduction in use is partially due to supply or consumption constraints, poor shelf life, unrecognised nutritional value, poor consumer awareness, and perception as famine food ("poor people's food"), which is partially due to the modernisation of agricultural practices. Some crops experienced genetic erosion of their gene pool due to this neglect, which resulted in them becoming regarded as lost crops. [9]

As the demand for plant and crop attributes changes (reappraisal or discovery of nutritional traits, culinary value, adaptation to climate change, etc.), some previously neglected crops, such as oil palm, soybean, and kiwifruit, have overcome such constraints via more large-scale production and use, becoming regarded as globally significant crops. [10] [11] Alongside their commercial potential, many underused crops such as sorghum provide essential environmental services as they have adapted to marginal soil and climate conditions. [12]

Under-utilised crops continue to play a vital role in the subsistence and economy of people in low and middle-income countries, particularly in the agro-biodiversity rich tropics. For example, chirimoya and bambara crops produced in Colombia and Mozambique respectively, aid the local population in food security, allowing them physical and economic access to sufficient food for meeting their dietary needs, even during a famine. [13] [14]

Definition

There is no consensus on what defines an under-utilised crop, but they often display the following attributes:

Neglected crops are primarily grown by traditional farmers. These species may be widely distributed beyond their centers of origin but tend to occupy unique niches in the local production and consumption systems. They are critical for the subsistence of local communities yet remain poorly documented and neglected by mainstream research and development activities. [16] Many staple crops, especially in the developing world, are poorly studied by researchers. For example, the Green Revolution saw massive changes in agricultural productivity in Asia, but African crops saw little benefit. [17]

Determination of the underutilized status of a crop varies among researchers. Different criteria and approaches are used to define this particular group of crops. Neglect refers to the lack of attention a crop may receive through research and development and can be evaluated by how well national and international policy or legal frameworks and research and development programs can support the conservation and sustainable use of a crop. Under-utilisation is particular to the geography and potential for a crop to contribute to better diets and production systems. In cases where exotic or diversified species are under-utilised in a particular region, these may not necessarily be under-utilised in other parts of the world. [9] Below is a non-exhaustive list of neglected and under-utilised species.

It is important to recognise the potential negative impact on communities that historically use so-called under-utilised crops. As these crops come under international focus, Quinoa in South America as an example saw its price surge by 600%, pushing the coveted grain outside the reach of traditional use communities. [18]

<span class="mw-page-title-main">Quinoa</span> Edible plant in the family Amaranthaceae

Quinoa is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are rich in protein, dietary fiber, B vitamins and dietary minerals in amounts greater than in many grains. Quinoa is not a grass but rather a pseudocereal botanically related to spinach and amaranth, and originated in the Andean region of northwestern South America. It was first used to feed livestock 5,200–7,000 years ago, and for human consumption 3,000–4,000 years ago in the Lake Titicaca basin of Peru and Bolivia.

The International Treaty on Plant Genetic Resources for Food and Agriculture, is a comprehensive international agreement in harmony with the Convention on Biological Diversity, which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources for food and agriculture (PGRFA), the fair and equitable benefit sharing arising from its use, as well as the recognition of farmers' rights. It was signed in 2001 in Madrid, and entered into force on 29 June 2004.

<span class="mw-page-title-main">Legume</span> Plant in the family Fabaceae

Legumes are plants in the family Fabaceae, or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption; for livestock forage and silage; and as soil-enhancing green manure. Well-known legumes include beans, chickpeas, peanuts, lentils, lupins, mesquite, carob, tamarind, alfalfa, and clover. Legumes produce a botanically unique type of fruit – a simple dry fruit that develops from a simple carpel and usually dehisces on two sides.

<span class="mw-page-title-main">Cowpea</span> Species of plant

The cowpea is an annual herbaceous legume from the genus Vigna. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant's root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to intercropping with other crops. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name.

<i>Vigna subterranea</i> Species of plant

Vigna subterranea is a member of the family Fabaceae. Its name is derived from the Bambara ethnic group. The plant originated in West Africa. As a food and source of income, the Bambara groundnut is considered to be the third most important leguminous crop in those African countries where it is grown, after peanut and cowpea. The crop is mainly cultivated, sold and processed by women, and is, thus, particularly valuable for female subsistence farmers.

<i>Annona</i> Genus of fruits and plants

Annona or Anona is a genus of flowering plants in the pawpaw/sugar apple family, Annonaceae. It is the second largest genus in the family after Guatteria, containing approximately 166 species of mostly Neotropical and Afrotropical trees and shrubs.

<span class="mw-page-title-main">Agricultural biodiversity</span> Agricultural concept

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 that provide food and non-food agricultural products.” It is managed by farmers, pastoralists, fishers and forest dwellers, agrobiodiversity provides stability, adaptability and resilience and constitutes a key element of the livelihood strategies of rural communities throughout the world. Agrobiodiversity is central to sustainable food systems and sustainable diets. The use of agricultural biodiversity can contribute to food security, nutrition security, and livelihood security, and it is critical for climate adaptation and climate mitigation.

<i>Bactris gasipaes</i> Species of palm

Bactris gasipaes is a species of palm native to the tropical forests of Central and South America. It is well spread in these regions, where it is often cultivated by smallholders in agroforestry systems or more rarely, in monoculture. Common names include peach palm in English, among others used in South American countries. It is a long-lived perennial plant that is productive for 50 to 75 years on average. Its population has an important genetic diversity, leading to numerous fruits, colors, and qualities. The fruits are edible and nutritious but need to be cooked for 30 minutes to five hours. They also benefit many animals in the wild. Peach-palms are also cultivated for the heart of palm, and the trunk can make valuable timber.

<i>Annona reticulata</i> Species of tree

Annona reticulata is a small deciduous or semi-evergreen tree in the plant family Annonaceae. It is best known for its fruit, called custard apple, a common name shared with fruits of several other species in the same genus: A. cherimola and A. squamosa. Other English common names include ox heart and bullock's heart. The fruit is sweet and useful in preparation of desserts, but is generally less popular for eating than that of A. cherimola.

A crop wild relative (CWR) is a wild plant closely related to a domesticated plant. It may be a wild ancestor of the domesticated (cultivated) plant or another closely related taxon.

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 each crop and the number of species commonly grown.

Deficit irrigation (DI) is a watering strategy that can be applied by different types of irrigation application methods. The correct application of DI requires thorough understanding of the yield response to water and of the economic impact of reductions in harvest. In regions where water resources are restrictive it can be more profitable for a farmer to maximize crop water productivity instead of maximizing the harvest per unit land. The saved water can be used for other purposes or to irrigate extra units of land. DI is sometimes referred to as incomplete supplemental irrigation or regulated DI.
