Soil Maps to Help Kenyan Farmers Boost Yields

Kenyan farmers will be able to get free information on the nutritional condition of farm soils, enabling them to decide the amount and type of fertiliser to use. A project known as the African Soil Information Service (AfSIS) has been initiated by the country’s Ministry of Agriculture and is being coordinated by Nairobi-based International Centre for Tropical Agriculture (CIAT). The initiative involves production of the first-ever, detailed digital soil map for all 42 countries in sub-Saharan Africa. The data provided at the regional, national and local levels will help farmers and agricultural experts to identify the best ways for improving crop production through better soil management. The information will be provided free of charge after the completion of digital soil mapping in the country, and in 41 other African states, in the next four years. “The main problem facing our farmers on fertiliser use is lack of information on how to use the products. This initiative will help farmers improve fertiliser use,” said Wilson Songa, the permanent secretary in the Ministry of Agriculture. The project combines the latest soil science and technology with remote satellite imagery and on-the-ground efforts to analyse thousands of soil samples from remote areas across the continent. The maps will be supplemented by weather maps to help agricultural extension officers to give better advise to farmers. The information will also be availed to the extension officers through mobile phones, the Internet and the media, among others. The project combines the latest soil science and technology with remote satellite imagery and on-the-ground efforts to analyse thousands of soil samples from remote areas across the continent. Production of the map will involve use of scanning equipment to produce wavelengths in the soil which will then be analysed for nutritional content. It will use remote sensing technology via satellite to create detailed images of large areas indicating nutrients, moisture and organic matter in the soil. Work on the AfSIS is supported through a four-year grant from the Bill & Melinda Gates Foundation and the Alliance for a Green Revolution in Africa (AGRA). CIAT’s Nairobi-based Tropical Soil Biology and Fertility (TSBF) Institute will lead the effort. Source : http://www.bdafrica.com

Antarctica is warming, not cooling

Antarctica is getting warmer rather than cooling as widely believed, according to a study that fits the icy continent into a trend of global warming.

A review by U.S. scientists of satellite and weather records for Antarctica, which contains 90 percent of the world’s ice and would raise world sea levels if it thaws, showed that freezing temperatures had risen by about 0.5 Celsius (0.8 Fahrenheit) since the 1950s.

A review by U.S. scientists of satellite and weather records for Antarctica, which contains 90 percent of the world’s ice and would raise world sea levels if it thaws, showed that freezing temperatures had risen by about 0.5 Celsius (0.8 Fahrenheit) since the 1950s.

The average temperature rise was “very comparable to the global average,” he told a telephone news briefing.

Skeptics about man-made global warming have in the past used reports of a cooling of Antarctica as evidence to back their view that warming is a myth.

Cooling at places such as the South Pole and an expansion of winter sea ice around Antarctica had masked the overall warming over a continent bigger than the United States where average year-round temperatures are about -50 Celsius .

The scientists wrote that the Antarctic warming was “difficult to explain” without linking it to manmade emissions of greenhouse gases, mainly from burning fossil fuels.

Chinese version of “Google Earth”

China: The State Bureau of Surveying and Mapping (SBSM) launched a programme to set up a service platform on national geographic information for the general public. The move, disclosed at a national conference for directors of surveying and mapping bureaus recently held, marks fundamental changes in China’s traditional services to supply basic geographic information. Upon completion, the programme will provide comprehensive online geographic information services similar to “Google Earth” and “Google Maps” to all types of institutions and to the general public.

Big Oily Water Spill at Alaska Field

A corroded pipeline ruptured on Christmas Day at ConocoPhillips’ Kuparuk oil field in Alaska, causing one of the biggest-ever spills of oil-laced water on the North Slope, the Alaska Department of Environmental Conservation (DEC) said on Tuesday.

The 94,920-gallon spill from a corroded water-injection pipeline had little effect on production from North America’s second-biggest field and was mostly cleaned up by Tuesday, department officials said.
