Charting new ?sustainable agricultural pathways? in Brazil.
Provedor de dados: 14
Autores: LOPES, M. A.
Brazil is a large country spanning several climatic zones. Its bountiful supplies of fresh water, abundant solar radiation and rich biodiversity have enabled it to become one of the world?s largest producers of food, feed, fibers and renewable fuels. But it is not these natural endowments alone that put Brazil decisively on this pathway: it is also the country?s advanced capacity in technology development, put to use over decades. Now, that same capacity is being directed towards a sustainable future. Charting new ?sustainable agricultural pathways? will revitalize Brazil?s landscape and serve as a model for countries facing similar challenges across the planet?s tropical belt.

Remediation of Soils Contaminated by Pesticides Using Physicochemical Processes: a Brief Review
Provedor de dados: 87
Autores: BALDISSARELLI,D.P.; VARGAS,G.D.L.P.; KORF,E.P.; GALON,L.; KAUFMANN,C.; SANTOS,J.B.
ABSTRACT: After years of pesticide application, often indiscriminately, damage has been caused to the environment, as well as to agronomic crops grown in contaminated areas. In water treatment, techniques based on physical and/or physicochemical processes are used, being formed secondary oxidizing agents responsible for the mineralization of contaminants present in the herbicides, thus causing the degradation process. However, few studies have demonstrated the effectiveness of these techniques in soils. The aim of this study was to review the existing studies, presenting the main techniques used for remediation of soils contaminated with pesticides. Emphasis was placed on electrokinetics, advanced oxidative processes, soil washing, chemical or solvent...

Autores: Popp,   Jozsef.
This paper focuses on global responsibility of food, energy and environmental security. World population growth will lead to increasing demand for food and feed with increasing meat consumption. With globalization and urbanization production is moving to the most competitive countries and regions, and food trade is becoming more liberalized but also more concentrated. Growing energy demand and climate change will also influence food production. Additional challenges are increasing market volatility resulting from yield and climate change. We need greater responsibility in cutting greenhouse gas (GHG) emissions, in showing greater respect for the environment. More responsibility is needed regarding food and energy security, and environmental sustainability....

Ecosystem Services and Food Security: Economic Perspectives on Environmental Sustainability
Provedor de dados: 31
Autores: Richardson,   Robert B.
Food security in developing countries depends in part on the sustainable use of natural resources. Food security is usually examined through three dimensions, namely the availability, access, and utilization of food. Ecosystems directly and indirectly support each of these dimensions through the provision of critical ecosystem services that facilitate agricultural production, create income- generating opportunities, and provide energy for cooking. However, in some cases, household uses of natural resources undermine particular elements of  food security, hindering national poverty reduction strategies and threatening the sustainability of critical ecosystem functions. I examine the role of ecosystem services in rural food security through the lens of its...

Maize boom in the uplands of Northern Vietnam : economic importance and environmental implications
Provedor de dados: 31
Autores: Keil,   Alwin; Saint-Macary,   Camille; Zeller,   Manfred.
In Vietnam, the demand for meat products has grown dramatically due to rapid economic growth and urbanisation and is expected to further increase in the future. Being the primary source of feed for the country’s livestock and poultry industry, maize has become the second most important crop after rice. While this maize boom has the potential to reduce rural poverty, it promotes the expansion of agricultural cultivation into fragile agro-ecological zones, often leading to deforestation and soil degradation, especially in the uplands. Using empirical evidence from mountainous Yen Chau district in north-western Vietnam, the objective of this paper is to investigate the current economic importance and environmental implications of maize cultivation....

ABSTRACT: Mechanical sugarcane harvesting increases soil compaction due to the intense traffic of agricultural machinery, reducing longevity of sugarcane crops. In order to mitigate the harmful effects caused by agricultural traffic on the soil structure in sugarcane fields, this study evaluated impacts of mechanical sugarcane harvesting on traffic lane under two soil tillage systems based on load bearing capacity models. The experiment was carried out in the region of Piracicaba, state of São Paulo, Brazil, on a Rhodic Nitisol, under conventional tillage (CT) and deep strip-tillage (DST). For CT soil tillage was applied to the entire area with a heavy disk harrow, at operating depths from 0.20 to 0.30 m followed by a leveling harrow at a depth of 0.15 m....

ABSTRACT: The objective of this study was to evaluate the effects of the addition of sugarcane juice on the population dynamics of Escherichia coli and the presence of Shiga-toxigenic E. coli (STEC) during the anaerobic codigestion of dairy cattle manure. For the overall analyses at the end of a hydraulic retention time of 90 days, ten two-liter batch-type biodigesters were divided into two treatment groups: biodigester containing manure and water (MW) and the biodigester containing manure, water and sugarcane juice (MSC). For monitoring the population dynamics and presence of microorganisms, pH, and volatile acidity, tests were carried out every ten days, on 36 smaller-scale batch biodigesters made of one-liter plastic bottles (18 for each treatment).
