Considering that the species has not yet been introduced into Argentina, the climate of its original area was studied in detail. Table 2 shows the agroclimatic indices that define each class of agroclimatic suitability. To create the maps, a series of previously interpolated bioclimatic variables were used. Argan tree plays a vital role in maintaining the ecological balance and the economic situation of the population. Argentina’s political map, with the toponomy of the provinces, was included to aid in the identification of the classified areas with different grades of agroclimatic fitness (Figure 1). Basic data in determining this similarity were the amount of annual rainfall, the annual temperature, the annual minimum temperature, the winter maximum temperature, the minimum temperature of the coldest month, the mean annual minimum temperature, and the annual maximum temperature. The women who are doing this work, call for a better salary and fair living and working conditions." Polyunsaturated fatty acids constitute approximately 80% of argan oil, and 30% of it is linoleic acid. The successful … Argan Biosphere Reserve extends over 2.5 million hectares in the semi-desert of south-western Morocco. The dry season is inordinately long, resulting in a short growing season. Brightening. Annual rainfall is scarce (232 mm) and concentrated from October to April. One of these areas is Admine Forest (hereafter Coastal Browsing, 30°26′54.13′′N and 9°32′49.90′′W, located in the suburbs of Agadir city, 5 km inland, 107 m of altitude), which different authors [22–24] consider as the ecological optimum for the species and the center of its distribution area. Goats digest the fleshy part of the fruit, but discharge the nut because of its hard shell. Saadia’s son in law was teaching in a town called Ait Daoud in Essaouira province and he came to know this gentleman well a few years ago. First, we had to identify the requirements, limits, and biometeorological tolerance and conditions to establish the potential growing areas. Starting in Essaouira and extending to Goulmime, and from the High Atlas to the Atlantic Ocean, it covers more than 828,000 ha [3]. In this article, you’ll learn a great deal about the argan tree. Flowering occurs mainly in spring, with great differences among individuals, and with a secondary peak in autumn. The agroclimatic indices, which determine different classes of suitability, were integrated in a Geographic Information System (GIS) to create thermal and moisture regions. Sign up here as a reviewer to help fast-track new submissions. Some of these new crops ameliorate the effects of increased atmospheric CO2 (greenhouse effect), which turns fertile lands into deserts by increasing temperature and producing drought [15]. Climatic interpolations were made using the “Interpolate to Raster” tool, within the “3D Analyst” extension of the GIS of the same program, following the Ordinary Kriging interpolation method.

M. El Yousfi, and M. Bendaanoun, D. Rivera and J. Germination takes up to a month. 2018, Article ID 9262659, 10 pages, 2018. https://doi.org/10.1155/2018/9262659, 1Climate and Water Institute, INTA, Las Cabañas y Los Reseros, s/n, Castelar, Buenos Aires, Argentina, 2Laboratorio de Cultivo Experimental de Plantas y Microalgas, Departamento de Biodiversidad y Biología Experimental, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, Buenos Aires, Argentina, 3Instituto de Micología y Botánica (INMIBO), Universidad de Buenos Aires-CONICET, Buenos Aires, Argentina, 4Centro de Investigaciones y Estudios Ambientales (CINEA), Facultad de Ciencias Humanas (FCH), Universidad Nacional del Centro de la Provincia de Buenos Aires (UNICEN), Campus Universitario, Paraje Arroyo Seco, s/n, Tandil, Argentina. The altitudinal range of the argan tree extends from sea level up to 1,300–1,500 m. The annual rainfall varies from 250 mm in Safi to 400 mm in Agadir. Argan oil is rich in unsaturated fatty acids and vitamin E. The tree is native to southern Morocco, where it grows in open forests up to an altitude of more than 5,000 feet. Although Argentine territory extends towards the Tropic of Capricorn (23°27′S), it lacks tropical climates. Take care not to damage their delicate taproot when planting. Plant the seedlings in a mixture containing three parts soil to one part peat moss and one part humus. The crown has a circumference of about 70 m (230 ft) and the branches lean towards the ground. ITIS, “Catalogue of Life: 2014 Annual Checklist,” 26 November 2015, JP. Argan trees in nature receive up to 39 inches of rain per year. In the coastal areas where argan trees grow, there are temperate oceanic influences with moderate temperatures (annual average in Agadir is 18.5°C; minimum temperature of coldest month: 7.4°C) and low annual and daily thermal amplitude [14]. To determine agroclimatic suitability, the average climatic data of all the meteorological stations (1981–2010) were analyzed. Grow argan from seed planted in 3-inch plastic pots. The argan tree is a slow-growing spiny tree and is either shrubby or up to 10 m high when isolated and growing in a favorable environment [2]. The tree flourishes in areas where annual mean temperatures fluctuate between 18 and 20°C. Make a healthy soil combination by combining one part humus, one part peat moss, and 2 parts loam. The agroclimatic zoning map was obtained by superimposing the maps related to moisture and thermal regimes. Another index is the annual mean maximum temperature, which should surpass 23.0°C to ensure an appropriate thermal regime during the growing period [14]. Scarce and scattered spiny shrubs are the main woody vegetation. Plant the seeds 2 inches deep in a damp soil mixture made up of two parts loam, one part peat moss and one part humus. Argan tree plays a vital role in maintaining the ecological balance and the economic situation of the population. Keep them in dark and change the water every day. The 23°C isotherm covers the north and a large section of the center of the country. Argentina’s winter lasts from June to August. Climatic characteristics of area of origin of the argan tree (elaborated by the authors based on [. According to [21], the winter mean maximum temperature should be higher than 17.5°C. Download this stock image: Fresh Argan nuts growing on an Argon tree. The minimum temperature of the coldest month (in Argentina, July) is, by definition, the minimum monthly temperature occurrence over a 30-year period (normal) and it should be above 3.8°C [2]. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The argan tree is disseminated from Safi (north) to the Drâa River (south), and isolated populations extend as far as Tindouf, well inside the Western Sahara. According to [13], the argan tree prospers in desert or arid (Bw), steppe or semiarid (Bs) climates, between 20 and 32° latitude. The dietary and nutritional properties of argan oil are superior to those of extravirgin olive oil. In a way, they are similar to the mangrove trees that are preventing floods in the area they grow in. We are committed to sharing findings related to COVID-19 as quickly as possible. Copyright © 2018 Silvia L. Falasca et al. These are areas with mostly lithosols and regosols soils, associated with saline soils on lowlands. There are no optimal zones for the argan tree in Argentina. In some regions, it is already damaged, and its future is endangered by prolonged drought periods and desertification. These researchers maintain that argan tree is one of the few surviving relict-breed species of the Tertiary Period, which spanned from 65 million to 1.8 million years ago. These trees are warm region plants only, but growing macadamia nuts in southern California and other areas with tropical climates is possible. Trouvez les Argan Tree images et les photos d’actualités parfaites sur Getty Images. The resulting maps were superimposed to determine the agroclimatic zoning. Alex Bramwell started writing in 2002 and spent six years in the field of writing and editing news reports in the business, finance and technology sectors. As a result, fruit production extends over a long period and fruits can be found in different ripening phases from April to September [3] in the north hemisphere. The nuts are later collected by farmers to produce oil. In Figure 8 the mean annual minimum temperature of −5°C is shown. In Spain, there are specimens in Alicante, Murcia, Gran Canaria (Canary Islands), and Barcelona (38,06°N/1,17°W, 38,42°N/0,42°W, 27,10°N/15,10°W, 38,41°N/0,42°W, 38,33°N/0,54°W, 38,51°N/0,53°W, 38,41°N/0,42°W, 41,10°N/2,10°E, and 41,36N°/2,16°E). Investors, on the other hand, frequently fail because they lack adequate information concerning the risks and uncertainties related to these ventures. Under arid conditions there is another area classified as suitable with constraints which covers parts of the provinces of San Mendoza, San Juan, and La Rioja. The aim of this work was to design an agroclimatic zoning model to define the potential growing areas for Argania spinosa in Argentina. The “argan” ingredient is actually oil that comes from an argan tree. For instance, they sometimes put at risk the sustainability of the ecosystem where implantation is purported, or they ignore the agroclimatic requirements of the species. The second area is Tassademt (hereafter Mountain), a site located 70 km NE of Agadir in the first foothills of the Atlas Mountains, which is characterized by its extreme climatic conditions. Clear Skin. The suitable areas are those where the average minimum temperature is above −5°C. 2. According to [13], the tree dies with frosts of −2°C, although according to [18] it can tolerate −5°C.
