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.Abstract:
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 meet the demands of improving yields without compromising environmental integrity or public health.read more

Agricultural land change in the Carpathian ecoregion after the breakdown of socialism and expansion of the European Union
TL;DR: In this article, the authors assess agricultural land change for the entire Carpathian ecoregion in Eastern Europe at 30 m spatial resolution with Landsat data and for two change periods, between 1985−2000 and 2000−2010.

Grain yields in relation to N requirement: Optimizing nitrogen management for spring maize grown in China
Peng Hou,Qiang Gao,Ruizhi Xie,Shaokun Li,Qingfeng Meng,Ernest A. Kirkby,Volker Römheld,Torsten Müller,Fusuo Zhang,Zhenling Cui,Xinping Chen +10 more
TL;DR: The overestimation of nitrogen uptake requirement under a high-yield cropping system with maize (Zea mays L.) has been a driving force in the overuse of N fertilization and environmental pollution in China as mentioned in this paper.

The next protein transition
Harry Aiking,Joop de Boer +1 more
TL;DR: In this article, a multidisciplinary perspective is required to sketch why a transition from diets based primarily on animal proteins towards diets based on plant proteins products is extremely urgent for both food security and sustainability.
Journal ArticleDOI
Strategies and models for agricultural sustainability in developing Asian countries
TL;DR: In the proposed ‘biovillage paradigm’, eco-friendly agriculture is promoted along with on- and non-farm eco-enterprises based on sustainable management of natural resources and ecotechnologies and the twin goals of ecoagriculture and eco-livelihoods are addressed.

Climate change 2001: the scientific basis
John Theodore Houghton,Y. Ding,David John Griggs,M. Noguer,P. J. van der Linden,X. Dai,K. Maskell,C. A. Johnson +7 more
TL;DR: In this article, the authors present an overview of the climate system and its dynamics, including observed climate variability and change, the carbon cycle, atmospheric chemistry and greenhouse gases, and their direct and indirect effects.

Human Domination of Earth's Ecosystems
TL;DR: Human alteration of Earth is substantial and growing as discussed by the authors, between one-third and one-half of the land surface has been transformed by human action; the carbon dioxide concentration in the atmosphere has increased by nearly 30 percent since the beginning of the Industrial Revolution; more atmospheric nitrogen is fixed by humanity than by all natural terrestrial sources combined; more than half of all accessible surface fresh water is put to use by humanity; and about one-quarter of the bird species on Earth have been driven to extinction.

Human alteration of the global nitrogen cycle: sources and consequences
Peter M. Vitousek,John D. Aber,Robert W. Howarth,Gene E. Likens,Pamela A. Matson,David W. Schindler,William H. Schlesinger,David Tilman +7 more
TL;DR: In this article, a review of available scientific evidence shows that human alterations of the nitrogen cycle have approximately doubled the rate of nitrogen input into the terrestrial nitrogen cycle, with these rates still increasing; increased concentrations of the potent greenhouse gas N 2O globally, and increased concentration of other oxides of nitrogen that drive the formation of photochemical smog over large regions of Earth.

Nonpoint pollution of surface waters with phosphorus and nitrogen
Stephen R. Carpenter,Nina F. Caraco,David L. Correll,Robert W. Howarth,Andrew N. Sharpley,Val H. Smith +5 more
TL;DR: In this article, a review of the available scientific information, they are confident that nonpoint pollution of surface waters with P and N could be reduced by reducing surplus nutrient flows in agricultural systems and processes, reducing agricultural and urban runoff by diverse methods, and reducing N emissions from fossil fuel burning, but rates of recovery are highly variable among water bodies.
