Special Issue Information

Dear Colleagues,

The demand for food, fiber and biofuel to supply a growing population has led to the intensification of the input requirement by agriculture. Some environmental counter effects and the necessity to reduce cost production made the rational use of inputs become a goal of managers and decision makers.

Global awareness of environmental issues has increased and become a theme approached by consumers and policy making, used as an international trade barrier and even propitiated the creation new market niches.

Environmental evaluation on agricultural production systems is approached in many ways. However, a complete quantitative assessment requires time and effort, which, in most of cases, resulted in limited studies in terms of environmental impact.

To supply subsidies to the environmental awareness it was necessary to adopt a wider and systemic approach. This is because the high complexity of biosystems requires managers to deal with controllable (e.g., inputs, energy) and non-controllable, but predictable (e.g., weather, market) aspects that directly affect agricultural production systems. Data collection and treatment to subsidize decision making became vital.

Historically, agricultural engineering has played an important role on designing of farm assets, propitiating adequate management for the production system of crops, forests and livestock, aiming for higher efficiency of production processes. The most recent technological development has provided several hardware and software options able to make data acquisition easier. Therefore, there are opportunities to used data from the digitalization process of agriculture to support managers.

Technological options are rapidly growing, which can contribute for monitoring and further improvement of the current systems.

The demand for innovative and less impacting solutions to minimize the environmental footprint of vegetable and animal production will be continuously required.

This Special Issue centers on novel trends in environmental footprints to highlight the solutions performed and which path should be followed to achieve higher efficiency of agricultural and biological systems. All types of manuscript submissions are welcomed and will follow a rigorous peer-review process.

We are looking forward to an extraordinary Special Issue, displaying trends on environmental aspects to become part of decision making.

The exploitation of natural resources for agriculture is growing to fulfill the demand for food, which requires the rational use of inputs for sustainable production. Brazilian agricultural production stands out on the international scene. For instance, corn is one of the most exported products in Brazil, which is possible through the planting in the second crop season within a year, called the “off-season”. In addition to being a technique that allows soil conservation, it also reduces the use of inputs and soil tillage. The agricultural production systems require a large amount of energy throughout their processes, mainly through inputs and fuels. Energy flows allow for the identification of the efficiency of the production system and, consequently, its sustainability. Indicators regarding net energy gain per area (Energy balance) and energy profitability (Energy Return on Investment) were applied. The first-season system presented higher energy demand when compared to the second-season system, with a difference of 10.24 GJ ha−1 between the conventional ones and 10.47 GJ ha−1 between the transgenic ones. However, the indicators showed higher energy efficiency in the transgenic off-season corn production, in which the return on energy was 55% higher, and the energy incorporation was 35% lower when compared to conventional first-season corn.
