Why is Ecological Intensification Important?

World population is expected to increase from the current 6.5 billion to over 9 billion by 2050. This represents an approximate 40% increase in just over 40 years. An obvious question is “where will we get the needed food, fiber, and fuel for all these additional people”? Another question that arises is “how much impact will this have on environmental quality?” The answer to these questions can at least partly be found in the concept and practice of ecological intensification (EI) of cropping systems. The following points generally address why EI is important to the future of world agriculture.

Is Switchgrass a Low Nutrient Input Crop or Not?



A new topic in the the Plant Nutrition Today series examines the nutrient requirements for switchgrass grown for energy.

Global Crop Intensification Lessens Greenhouse Gas Emissions

The global population increased from 3.08 billion in 1961 to over 6.51 billion in 2005 (111% increase), and is expected to reach almost 9 billion by 2050. This growth of the human family will result in a 70% rise in food demand. Can such food production increases be met, and if so, what will the impacts be on greenhouse gas (GHG) emissions and climate change?

Ecological Intensification of Irrigated Corn and Soybean Systems



Presentation by Achim Doberman discussing variability of yield potential of corn and soybeans, and how management techniques, including environmental factors, affect the attainable yield.

Open presentation

 Ecological Intensification of Irrigated Corn and Soybean Cropping Systems



This experiment seeks to (1) quantify and understand the yield potential of corn and soybean under irrigated conditions, (2) identify efficient crop management practices to achieve yields that approach potential levels, and (3) determine the energy use efficiency, global warming and soil carbon sequestration potential of intensively managed corn systems.
