MEXICO CITY, Oct 31 (Tierramérica).- The aquifer that supplies water to Mexico City could be recharged in eight areas, according to a new university research study.
"There are conditions favorable to groundwater recharge in numerous sites, which is an important factor for integrated water management," researcher Víctor Díaz of the School of Engineering at the National Autonomous University of Mexico told Tierramérica.
Díaz is the author of the report "Representación cartográfica del cambio climático" (Climate Change Mapping), which assesses the water supply situation in the Mexican capital, home to 8.8 million people.
The aquifer is seriously overexploited, given that 40 cubic meters of water per second (m3/s) are extracted while the recharge rate is only 19 m3/s. Precipitation contributes 216 m3/s, but 37 m3/s are lost through drainage.
Activists Call for Common Front to Defend Whales
BUENOS AIRES, Oct 31 (Tierramérica).- More than 60 environmental organizations from throughout Latin America and the Caribbean have called on the region’s governments to use diplomatic action to stop Japan from beginning its annual whale hunt in the Southern Ocean this December.
Japan claims that it hunts whales for scientific research purposes, which is authorized, but activists say that it actually does so for economic purposes, despite the moratorium on commercial whaling established by the International Whaling Commission (IWC) in 1986.
The environmentalists want the Buenos Aires Group, made up of the governments of 14 IWC member countries in the region, to issue a statement on what they view as a transgression of the commission’s rules.
"This request will be positively answered by the Argentine government and, through the Buenos Aires Group, Latin America will continue to express its firm opposition to these operations,” activist Roxana Schteinbarg of the Whale Conservation Institute of Argentina told Tierramérica.
Proposal to Compensate National Park for Water Supply
TEGUCIGALPA, Oct 31 (Tierramérica).- This November the Honduran Congress will study a bill aimed at authorizing payment for environmental services to La Tigra National Park, the main green area and source of water for Tegucigalpa.
Under the system proposed by the draft legislation, households that consume drinking water supplied by the national park will pay the equivalent of a dollar and a half extra on their water bills to contribute to its protection and preservation, Dolores Valenzuela of the environmental organization Amitigra told Tierramérica.
La Tigra is the source of water for five municipalities in the central department of Francisco Morazán, including Tegucigalpa.
Covering a total of 243,406 square kilometers, the park is home to broadleaf forests, six endangered fern species, white-tailed deer, ocelots, pumas and quetzals. *Source: Inter Press Service.
