Agricultural sustainability and intensive production practices

  title={Agricultural sustainability and intensive production practices},
  author={David Tilman and Kenneth G. Cassman and Pamela A. Matson and Rosamond L. Naylor and Stephen Polasky},
A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to… 
A Sustainable Agriculture?
The defining challenge of sustainable agriculture is the production of food and other agricultural products at an environmental cost that does not jeopardize the food security and general welfare of
Sustainable Intensification of Agriculture – for Food and Nutritional Security
I have spent over 50 years of my working life pursuing ‘agricultural sustainability’ and have witnessed many changes, challenges and successes – both nationally and globally. The successes have
Challenges and opportunities for agricultural sustainability in changing climate scenarios: a perspective on Indian agriculture
Increasing population and related food demand always remain the most imperative challenges for the developing world. It could only be attained by an increased agricultural production based on
Increasing the efficiency of water use in crop production
: Agriculture is by far the largest user of water. Increasing the use efficiency of water is essential to sustainably provide food for humans and water for maintaining natural ecosystems. The
Reconciling agricultural productivity and environmental integrity: A grand challenge for agriculture
Agriculture meets a major human need and both affects and depends on all other life support systems. Current trends point to continued human population growth and ever higher levels of consumption as
Future protein supply


Agroecosystems, Nitrogen-use Efficiency, and Nitrogen Management
The magnitude of the scientific challenge should not be underestimated because it becomes increasingly difficult to control the fate of N in cropping systems that must sustain yield increases on the world's limited supply of productive farm land.
The transition to agricultural sustainability.

If the world fails to successfully navigate a transition to sustainable growth in agricultural production, the failure will be due more to a failure in the area of institutional innovation than to resource and environmental constraints.
Integration of environmental, agronomic, and economic aspects of fertilizer management
Lower rates of nitrogen fertilizer, applied later in the crop cycle, reduced the loss of nitrogen without affecting yield and grain quality, saving farmers money and reducing environmental costs.
▪ Abstract This review explores the potential energy, soil, and water constraints on highly productive agricultural systems. It focuses on the process of agricultural intensification during the past
Technical Report: Human Alteration of the Global Nitrogen Cycle: Sources and Consequences
This report is confident that human alterations of the nitrogen cycle have increased the quantity of organic carbon stored within terrestrial ecosystems and caused changes in the composition and functioning of estuarine and nearshore ecosystems, and contributed to long-term declines in coastal marine fisheries.
Ecological intensification of cereal production systems: yield potential, soil quality, and precision agriculture.

It is concluded that major scientific breakthroughs must occur in basic plant physiology, ecophysiology, agroecology, and soil science to achieve the ecological intensification that is needed to meet the expected increase in food demand.
Securing The Harvest: Biotechnology, Breeding And Seed Systems For African Crops By J De Vries;Gary Toenniessen
A critical assessment of the ways in which breakthroughs in biotechnology, participatory plant breeding, and seed systems can be broadly employed in developing and delivering more productive crop varieties in Africa's diverse agricultural environments is provided.
PHOSPHORUS IN THE ENVIRONMENT: Natural Flows and Human Interferences
▪ Abstract Phosphorus has a number of indispensable biochemical roles, but it does not have a rapid global cycle akin to the circulations of C or N. Natural mobilization of the element, a part of the
Legume-based cropping systems have reduced carbon and nitrogen losses
In agricultural systems, optimization of carbon and nitrogen cycling through soil organic matter can improve soil fertility and yields while reducing negative environmental impact. A basic tenet that
