BookletCorporate general interestAGRIS. El Sistema internacional de información sobre ciencias y tecnología agrícolas
Guía para los usuarios
2023AGRIS es una de las bases de datos más completas de literatura científica sobre la alimentación y la agricultura en todo el mundo. Accesible a través de un portal web, millones de registros bibliográficos en más de 90 idiomas están disponibles de forma gratuita para usuarios globales. Una red internacional de proveedores de datos, incluidos editores, gobiernos y organizaciones, proporcionan voluntariamente información (metadatos) sobre publicaciones científicas. Estos registros se presentan en formatos multilingües y con frecuencia incluyen enlaces al texto completo para conectar a los usuarios con la literatura científica en todo el mundo. En los últimos años, AGRIS ha evolucionado para convertirse en un recurso de información reconocido en todo el mundo al pasar del papel a lo digital y de un modelo centralizado a una red distribuida. Esta guía tiene como objetivo actualizar a la comunidad de AGRIS, en particular a aquellos que utilizan la base de datos de AGRIS para encontrar literatura científica sobre la alimentación y la agricultura, sobre las mejores formas de interactuar y buscar en la base de datos. -

ArticleJournal articleRecovery of tree communities on degraded tropical forests after restoration planting
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Increasing rates of deforestation in tropical rain forests have been linked to agricultural encroachment. How well trees recover into a more species rich ecosystem after restoration planting remains unclear. The aim of the study was to evaluate the recovery of communities of tree, assess the influence of understory vegetation like Acanthus pubescens, and Pennisetum urpureum, on the recovery in Kibale National Park (KNP), Uganda. We studied six restored forests fragments ranging in age from 3 to 16 years and three primary forests. Our results showed that although recovery with natural regeneration was more effective than restoration planting the latter enhanced recruitment of native tree seedling. Tree recovery was generally correlated with age so that species density and diversity increased although at different rates. A reverse pattern was found for dominance but no clear pattern was found for tree density. Understory vegetation like Acanthus pubescens and Pennisetum purpureum negatively correlated with species density, tree density and diversity but a positive correlation was found for dominance. Although restoration planting can enhance recovery, understory vegetation significantly affects recovery of degraded forests. This can affect the cost of restoration of degraded areas.

ArticleJournal articleWhy is artificial afforestation crucial for restoring nature? Studies on the dried bottom of Aral Sea, Kazakhstan
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The Aral Sea, formerly the fourth largest inland lake located in Central Asia, has reduced dramatically as it lost most of its volume due to the large-scale water withdrawal for the cultivation of irrigated crops starting from the 1960s. The desiccated seafloor has become a source of salt, sand, and dust transfer to the adjacent regions, negatively affecting human health and the environment by inhibiting the survival and growth of the vegetation. In response, to stabilize the saline sand blowing from the Aral seabed, multiple domestic and international efforts have been performed to establish vegetation cover with indigenous trees of Haloxylon species as well as other salt- and water-stress tolerant woody and herbaceous plants of the region. As part of the afforestation project supported by the Korea Forest Service (South Korea) in Kazakhstan, field studies examined the impacts of the afforestation on carbon stock and soil quality. The summarized findings are as follows: 1) growth of planted seedlings indicates the measurable sequestration of carbon, which ultimately help to estimate its contribution to climate change mitigation by calculating the atmospheric greenhouse gas reductions; 2) afforestation increased the soil organic matter content which is closely related to soil fertility; 3) afforestation improved soil chemical properties for plants and soil microbes; 4) soil amelioration effects by the afforestation were statistically similar to those by natural vegetation succession. However, the soil conditions in the natural succession area improved after almost 50 years versus about 15 years in the afforested area. This signifies the relative efficiency of afforestation activities and thus helps justify the investments made. Based on the studies, we recommend further research to raise the efficiency of afforestation in arid areas, thereby reinforcing ecosystem restoration and climate change mitigation.

Brochure, flyer, fact-sheetBrochureStandard operating procedure for soil available micronutrients (Cu, Fe, Mn, Zn) and heavy metals (Ni, Pb, Cd), DTPA extraction method 2022
Also available in:
No results found.The method provides a potential indicator of the plant available copper, iron, manganese and zinc, which are essential soil micronutrients for plant growth and living organisms. It can be used to extract heavy metals such as nickel, lead and cadmium assisting with conclusions as to their potential bioavailability. This method must be used in combination with suitable determination methods, for example, flame atomic absorption spectrometry, electrothermal atomic absorption spectrometry or inductively coupled plasma – optical emission spectrometry.
