Water shortages loom; technology, creative approaches offer solutions

Article Abstract:

The world's food supply will be threatened if water-use efficiency does not improve. Current water practices that enable the support of 250 million hectares of irrigation-based agriculture has resulted in the depletion of water resources. Water tables in areas such as India, China and the western Great Plains are being depleted at a rapid rate, and the growth of cities is resulting in further strains on the environment. Measures that would help ease the water pressures in the future include the increased use of drip irrigation and the reuse of municipal wastewater.

Farming's future in third world

Article Abstract:

Global food production exhibits a declining trend since 1980 after a period of sustained growth. Per-capita production of cereals such as corn, rice and wheat has remained stunted since the 1980s and shows a downward trend. World population has been growing steadily during the same period. New ways have to be devised to increase food production to maintain balance with the growth in population. Otherwise, the world is in for a major food crisis by the year 2025.

The plight of the bumblebee: with bees and other pollinators disappearing at an alarming rate, our fruits and vegetables may be in jeopardy

Article Abstract:

Some flower and fruit plants face extinction due to a decrease in pollinators such as bees, flies and bats. Factors that lead to their eradication include the reckless use of pesticides, mites and habitat destruction. The production of fruits and vegetables may decrease if the problem remains unattended.
