Small-scale farmers in the Brazilian Amazon collectively hold tenure over more than 12 million ha of permanent forest reserves, as required by the Forest Code. The trade-off between forest conservation and other land uses entails opportunity costs for them and for the country, which have not been sufficiently studied. We assessed the potential income generated by multiple use forest management for farmers and compared it to the income potentially derived from six other agricultural land uses.
There is a blossoming of voluntary certification initiatives for sustainable agro-food products and production processes. With these certification initiatives come traceability in supply chains, to guarantee the sustainability of the products consumed. No systematic analysis exists of traceability systems for sustainability in agro-food supply chains.
Colombia produces more sugar per month on one hectare of land than any other country. This privilege is due to the productivity of sugar cane grown in the Cauca River valley, where 14 processing plants operate nearly year-round to produce sugar, honey, bioethanol, and electrical energy. The cane is supplied by 2750 growers, owners of 75 percent of the 240 000 hecatres planted, and by the sugar mills themselves (25 percent of the area). The sugar cane chain provides more than 286 000 direct and indirect jobs.
Nicaragua is the largest country in Central America, and agriculture is one of the engines of economic and social development. The agricultural sector contributes 16.1 percent of the Gross Domestic Product (GDP), 33 percent of formal employment and the food security of the population. There are 260 000 producers involved in agricultural production.
Colombia produce más azúcar por mes en una hectárea de tierra que cualquier otro país. El privilegio se debe a la productividad de la caña de azúcar cultivada en el valle del río Cauca, donde 14 plantas procesadoras operan casi todo el año para producir azúcares, mieles, bioetanol y energía eléctrica. La caña es suministrada por 2750 proveedores, propietarios del 75 por ciento de las 240 000 hectáreas sembradas, y por los mismos ingenios o centrales azucareras (25 por ciento del área).
Nicaragua es el país más grande de América Central, y la agricultura es uno de los motores del desarrollo económico y social. El sector agrícola aporta el 16.1 por ciento del producto interno bruto (PIB), el 33 por ciento del empleo formal y la seguridad alimentaria de la población. Alrededor de la producción agropecuaria se integran 260 000 productores.
In recent years, the international status of agriculture in the BRICS countries—Brazil, Russia, India, China and South Africa—has been continuously improved. In 2018, the gross agricultural production of the BRICS countries accounted for more than 50% of the world’s total. Further strengthening the developing cooperation of the BRICS countries is of great significance for ensuring global food security.
The use of technology in agriculture plays an important role in the production chain cycle, as well as in the improvement of processes and productivity. To develop a model for measuring the technological capacity of family agriculture systems, it is necessary to assess the gaps related to indicators and the technological potentialities of these farmer groups, which are often not considered when they require financial support and do not get enough. Thus, the aim of this study is to identify the indicators used to evaluate the technological capacity of farm systems and agriculture.
Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physical properties have been predicted by reflectance spectroscopy successfully on subtropical and temperate soils, whereas soils from tropical agro-forest regions have received less attention, especially those from tropical rainforests. A spectral characterization provides a proficient pathway for soil characterization.
Rural extension plays a significant and irreplaceable role in an innovation system that creates, designs, validates, and promotes new ideas, solutions, technologies, and forms of management focused on the resolution of problems and satisfaction of the needs of farmers and rural inhabitants and the organizations that represent them. In view of the above, this document presents proposals for making rural extension a key part of innovation systems focused on rural territorial development.
