Addressing Research Bottlenecks to Crop Productivity

Buffer Aggregation: Addressing Queuing Subsystem Bottlenecks at High Speeds

Modern routers and switch fabrics can have hundreds of input and output ports running at up to 10 Gb/s; 40 Gb/s systems are starting to appear. At these rates, the performance of the buffering and queuing subsystem becomes a significant bottleneck. In high performance routers with more than a few queues, packet buffering is typically implemented using DRAM for data storage and a combination of ...

Crop productivity and adaptation to climate change in Pakistan

How effective adaptation practices in response to climate change are is a crucial question confronting farmers across the world. Using detailed plot-level data from a specifically designed survey conducted in 2013, this paper investigates whether there are productive benefits for farmers who adapt to climate change in Pakistan. The impact of implementing on-farm adaptation strategies is estimat...

Raising Crop Productivity in Africa through Intensification

The population of Africa will double in the next 33 years to reach 2.5 billion by 2050. Although roughly 60% of the continent’s population is engaged in agriculture, the produce from this sector cannot feed its citizens. Hence, in 2013 alone, Africa imported 56.5 million tons of wheat, maize, and soybean at the cost of 18.8 billion USD. Although crops cultivated in Africa play a vital role in t...

Update on Climate Change and Global Crop Productivity The Influence of Climate Change on Global Crop Productivity

Climate trends over the past few decades have been fairly rapid in many agricultural regions around the world, and increases in atmospheric carbon dioxide (CO2) and ozone (O3) levels have also been ubiquitous. The virtual certainty that climate and CO2 will continue to trend in the future raises many questions related to food security, one of which is whether the aggregate productivity of globa...
