Agricultural systems basically depend on ecological processes and services provided by ecosystems. These ecological processes and services, called ecosystem services or environmental services, relate to the conditions and processes through which ecosystems sustain human life by supplying provisions (food, timber, fiber and fuel production), regulation (of water, of climate, protection against droughts, flooding, storms, spread of diseases and soil degradation, waste purification), support (hydro

Environmental systems (SA) have gained great visibility as mechanisms of environmental conservation and improvement of living conditions for rural communities. However, when compared to services of provision of food, fiber and energy, SAs such as carbon sequestration and water conservation are generally put in an inferior level. Given its importance even to the sustainability of agriculture, it is necessary that these SAs move from the sphere of discourse into the sphere of practical realities.

A crescente demanda de água para fins industriais e residenciais, geração de energia, mineração, lazer, somados aos problemas ambientais, faz com que quantidade de água para a agricultura apresente uma tendência de redução. A agricultura é o maior usuário de água em todo o mundo. O setor agrícola brasileiro é o principal usuário consuntivo dos recursos hídricos. Uma provável solução para esse problema é aperfeiçoar como a água é manejada, o que envolve a adoção de tecnologias e procedimentos ade ...

Some results of practical interest to soil management can be extracted from the soil's water retention curve. The recent validation of the Arya and Paris model for Brazilian soils created excellent opportunities to expand the functionality of the soil granulometric analyzer which is used to obtain in detail the entire particle distribution curve. Since the granulometric analysis takes only 20 minutes, at the same time, through the developed computing implementation, the following results can als

From an economic point of view, Brazilian agribusiness has been recognized as modern, prosperous, profitable and competitive activity whose magnitude has established Brazil as a world agricultural power. The activity accounts for 26% of the gross domestic product, 42% of the volume of Brazilian exports, and 37% of the total number of jobs in the country. The finding from this scenario is that development in the country is strongly dependent on an increasing production of agricultural products

One of the challenges smallholders in Northern Ethiopia face is improving food security in periods of low rainfall supply by identifying strategies to restore soil water stocks. In that region, over 50% of the water available for agriculture is lost due to issues like direct evaporation, surface runoff and deep drainage. The hypothesis is that the use of low cost technologies and intelligent solutions to identify strategies for water resupply and/or water storage in low cost containers like c

Embrapa invests in the conservation of native strains of microorganisms, which can be used by the scientific community in several research programs, ranging from diagnosis, treatment of diseases and production of vaccines for human and animal application to reducing the environmental impact of Productive processes and the generation of renewable energy.

In this perspective, microbial cultures are being continuously studied for the formation of a database of "active" components and thei ...

The Precision Agriculture Network counts with 20 Embrapa research Units and approximately 200 researchers: 15 experimental units distributed throughout the Northeast, the Mid-West, Southeast and South of the country; 11 perennial and annual cultures, and approximately 100 Research, Development and Innovation activities. The network was started at the end of 2009, and proposed to establish agricultural and stockbreeding concepts focused on space-time variability management for the sustainability

The ‘cipó-titica’ vine (Heterops flexuosa) is a non-timber forest product of economical importance in Amapá. Its long and resistant aerial roots have historically been used for crafting furniture, utensils and handcrafts. The project will be situated in Nova Canaã settling, at Porto Grande municipality (Amapá) and aims to evaluate cipó-titica plants density in the forest in order to identify phorophytes (tree species that host the vine) and thus determine the rate of growth and emission of ne

The collared peccary ( Tayassu tajacu) are rustic and gregarious animals who provide meat and leather of excellent quality, being thus an important source of protein especially to the subsistence of the Amazon's needy population. The use of this animal is, however, being done without planned hunting, being thus associated with the destruction of their natural habitat and, consequently, the loss of these resources, which are scarcely known.

In this context, the market oriented cap ...
