Conference Paper 2004

Autor: Smith, Jimmy W. Keatinge, J.D.H. Smalley, M.E. Quiróz, R.

Expansion of global population each year at the rate of approximately 90 million more than the current population of The Philippines will also necessitate unprecedented expansion of food production. As there is little room to bring more land under cultivation, almost all of the increase must come...

Soil organic C (SOC), the largest terrestrial C pool, has been shown to be sensitive to agricultural disturbance. In the Andean Puna, agricultural expansion is thought to be jeopardizing the large SOC stock sequestered in its soils. In this paper, we assessed the impact changes in land use have o...

India aims to produce 125 million tonnes potatoes in 2050 for ensuring food security to its natives and for achieving this massive target the country needs to explore non-traditional areas. Rajasthan in general and Jodhpur district in particular are dominated by the arid climate. The state in gen...

Austral summer frosts in the Andean highlands are ubiquitous throughout the crop cycle, causing yield losses. In spite of the existing warming trend, climate change models forecast high variability, including freezing temperatures. As the potato center of origin, the region has a rich biodiversit...

Quantifying rainfall at spatial and temporal scales in regions where meteorological stations are scarce is important for agriculture, natural resource management and land-atmosphere interactions science. We describe a new approach to reconstruct daily rainfall from rain gauge data and the normali...

The potato processing industry has developed quickly during the past decade in India, and the demand for processing grade potato tubers has increased accordingly. As a consequence, potato market prices have dramatically risen, particularly in the southern states, where production is still limited...

Remotely sensed data are often used as proxies for indirect precipitation measures over data-scarce and complex-terrain areas such as the Peruvian Andes. Although this information might be appropriate for some research requirements, the extent at which local sites could be related to such informa...

Soil carbon sequestration is one approach to mitigate greenhouse gases. However, to reliably assess the quantities sequestered as well as the chemical structure of the soil carbon, new methods and equipment are needed. These methods and equipment must allow large scale measurements and the constr...
