TLDR
The data suggest that while yield declines exist in some LTEs, they are less common than previously thought, particularly at moderate yield levels.About:

Yield Trends Are Insufficient to Double Global Crop Production by 2050.
TL;DR: Detailed maps are presented to identify where rates must be increased to boost crop production and meet rising demands, which are far below what is needed to meet projected demands in 2050.
Journal ArticleDOI
The role of conservation agriculture in sustainable agriculture.
TL;DR: It is concluded that agriculture in the next decade will have to sustainably produce more food from less land through more efficient use of natural resources and with minimal impact on the environment in order to meet growing population demands.
Journal ArticleDOI
Meeting Cereal Demand While Protecting Natural Resources and Improving Environmental Quality
TL;DR: In this paper, the authors evaluate the potential for conserving natural resources while meeting increased demand for cereals, and conclude that avoiding expansion of cultivation into natural ecosystems, increased nitrogen use efficiency, and improved soil quality are pivotal components of a sustainable agriculture that meets human needs and protects natural resources.
Journal ArticleDOI
Productivity and management of rice–wheat cropping systems: issues and challenges
Jagadish Timsina,David J. Connor +1 more
TL;DR: In this paper, a review establishes realistic yield targets and discusses strategies and tactics to improve complementarity of the two crops by choice of cultivar, sowing time, mechanization, soil and water management, choice and combination of organic and inorganic fertilizers, management of weeds, pests and diseases, and the inclusion of other crops into the system, especially legumes.
Book ChapterDOI
Rice and Water
TL;DR: The Comprehensive Assessment of Water Management in Agriculture (CA) seeks answers to the question of how freshwater resources can be developed and managed to feed the world's population and reduce poverty, while at the same time promoting environmental security.

Yield Potential Trends of Tropical Rice since the Release of IR8 and the Challenge of Increasing Rice Yield Potential
TL;DR: Factors that cause poor grain filling and low biomass production of the NPT lines have been identified and selecting parents with good grain filling traits, introduction of indica genes into NPT's tropical japonica background, and a refinement of the original NPT design are expected to improve the performance of theNPT lines.

Long-Term Agroecosystem Experiments: Assessing Agricultural Sustainability and Global Change
TL;DR: The establishment of an international network to coordinate data collection and link sites would facilitate more precise prediction of agroecosystem sustainability and future global change.

Soil Management: Experimental Basis for Sustainability and Environmental Quality
Rattan Lal,B.A. Stewart +1 more
TL;DR: In this article, a model for assessing the effects of Soil Management on Productivity is proposed, based on the Tropics of the Amazon and the Semiarid Tropics.
Journal ArticleDOI
Changes in chemical properties of organic matter with intensified rice cropping in tropical lowland soil
TL;DR: In this paper, the chemical composition of soil organic matter (SOM) from four fields with different histories of rice cropping intensity and soil submergence was compared, and the increased phenolic character of these fractions may influence N cycling and the N supplying capacity of lowland soils supporting two or three annual crops of irrigated rice.
