Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Botany

Tim Wheeler mainly investigates Climate change, Agronomy, Crop yield, Crop and Anthesis. His work carried out in the field of Climate change brings together such families of science as Agriculture, Food chain and Environmental resource management. His Agriculture study combines topics from a wide range of disciplines, such as Natural resource economics and Management science.

Specifically, his work in Agronomy is concerned with the study of Sowing. His studies deal with areas such as Annual plant, Climate model and Yield as well as Crop yield. He interconnects Dry weight and Oryza sativa in the investigation of issues within Anthesis.

His most cited work include:

  • Climate change impacts on global food security (1203 citations)
  • High temperature stress and spikelet fertility in rice (Oryza sativa L.) (424 citations)
  • Temperature variability and the yield of annual crops (423 citations)

What are the main themes of his work throughout his whole career to date?

The scientist’s investigation covers issues in Agronomy, Climate change, Crop, Sowing and Agriculture. In his study, Crop productivity is strongly linked to Agroforestry, which falls under the umbrella field of Agronomy. His Climate change study incorporates themes from Environmental planning, Environmental resource management, Natural resource economics, Crop yield and Food security.

His study explores the link between Crop yield and topics such as Climate model that cross with problems in Yield and Agricultural productivity. His Crop research integrates issues from Temperature gradient, Global warming, Adaptation, Agricultural engineering and Yield. His Sowing research includes elements of Arachis hypogaea, photoperiodism and Water-use efficiency.

He most often published in these fields:

  • Agronomy (36.31%)
  • Climate change (27.39%)
  • Crop (21.66%)

What were the highlights of his more recent work (between 2011-2017)?

  • Climate change (27.39%)
  • Agronomy (36.31%)
  • Agriculture (17.20%)

In recent papers he was focusing on the following fields of study:

His primary areas of study are Climate change, Agronomy, Agriculture, Yield and Crop yield. His Climate model study in the realm of Climate change interacts with subjects such as Investment. Crop, Cultivar, Anthesis and Sowing are the core of his Agronomy study.

His work deals with themes such as Global warming, Agroforestry and Growing season, which intersect with Crop. As a member of one scientific family, he mostly works in the field of Agriculture, focusing on Natural resource economics and, on occasion, Water resources. His study focuses on the intersection of Food systems and fields such as Malnutrition with connections in the field of Environmental resource management.

Between 2011 and 2017, his most popular works were:

  • Climate change impacts on global food security (1203 citations)
  • Climate change impacts on crop productivity in Africa and South Asia (378 citations)
  • Brief History of Agricultural Systems Modeling (196 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Botany

His scientific interests lie mostly in Yield, Crop yield, Agronomy, Climate change and Agriculture. His Yield study integrates concerns from other disciplines, such as Weather and climate, Crop and Growing season. His Crop research includes themes of Agroforestry and Sorghum.

His Agronomy study frequently draws connections to adjacent fields such as Horticulture. His Climate change research incorporates elements of Natural resource economics and Food security, Food systems. The study incorporates disciplines such as Private sector, Management science and Systems simulation in addition to Agriculture.
