For the past 35 years, Professor Halim has actively promoted the protection and management of Egypt's coastal and marine environment.
Since 1975 he has made important contributions to the pollution monitoring and research activities of the Mediterranean Action Plan, and is leader of UNEP's Task Team on the State of the Marine Environment of the Red Sea and Gulf of Aden.
John Fagan Handley
Mr. Handley has since 1982 been Executive Director of the Groundwork Trust which is involved in the rehabilitation of degraded environments.
For the past six years he has led the Trust's "operation groundwork" which improves rural and urban environments.
Richard A. Hellman
A lawyer who for the past two decades has championed environmental legislation in the US.
As counsel to the US Senate Public Works Committee in 1972-76, he helped draft legislation on air and water quality, noise, solid wastes and toxic substances.
Mr. Hellman's work for ‘Friends of UNEP, USA’ and/or ‘U.S. Committee for UNEP’ ceased prior to the year 2000 and since then he does not represent UNEP or its views in any manner.
Hetian County Government
On the fringe of the Taklamakan Desert, Hetian County covers 4,300 square kilometres. There is an oasis of 710 square kilometres and 28,600 hectares are irrigated by melted snow. The annual rainfall is only about 38 mm. The three main natural problems of the county are spring drought, sand-laden wind, and salinisation of soil.
Before 1979 there were few trees. Since the establishment in 1980 of the "three north" protection forest system, 22,847 hectares of forest have been planted and a shelterbelt network established. As a result soil stayed moist, wind speeds were reduced and grain output raised from 60,000 tons to 100,000 tons. Cotton and edible oil output increased four times, and livestock numbers went up by 54%.
The county's achievement is an excellent example of reafforestation for sustainable development in harsh conditions.
Gome Gnohite Hilaire
Since 1985 Mr. Hilaire has mobilised youth in supporting environmental programmes in cote d'lvoire.
The "Association de la Jeunesse Ivoirienne pour la Sauvegarde de l'Environnement" is active in conservation of forests and ecosystems, desertification control, education and training.
In 1992 he created with other young Africans the "African Youth Coordination on Development and Environment" (AYCODE).
Thilo Walter Hoffman
Mr. Hoffmann, a Swiss national, is a committed conservationist. He continues active involvement in many fields including coast conservation and wetland protection in Sri Lanka.
He is an office bearer of the Wildlife and Nature Protection Society, actively involved in the preparation for the society's centenary in 1994. Much of Mr. Hoffmann's time and energies are now devoted to the study and conservation of birds and their habitats in Sri Lanka.
He is the chairman of the Ceylon Bird Club and of the Sri Lanka Section of ICBR. He represents IWRB, for whom he organises the annual waterfowl census. Mr. Hoffmann regularly publishes papers on birds and other conservation subjects.
Andrew D. Holleman
In 1988, at the age of 13, Andrew Holleman organised a successful community campaign to prevent a wetland in Chelmsford from being transformed into a sewage treatment leaching system. He was honoured by the US Environment Protection Agency with the 1988 Environment Merit Award.
Since then he has presented many speeches and lectures regarding the preservation of the natural environment to various groups in his state and across the USA.
David L. Holm
A pioneer in the treatment of drainage of toxic matter from inactive mines. In 1984 he designed a system to neutralise mine acidity which uses low-cost materials and does not require continued electrical and chemical inputs.
The system has been successfully used at three abandoned mines by the Colorado Department of Natural Resources. It is an environmentally-sound approach to pollution control in mining.
For the past three decades Dr. Holt, a marine biologist, has been a leader in marine mammal conservation.
He organised the 1976 Bergen Conference, which defined the status of marine mammals and led to the 1984 global plan of action for the conservation, management and utilisation of marine mammals.
His expertise contributed to the adoption in 1982 of the worldwide moratorium on commercial whaling by the international whaling commission, and the designation of the Indian Ocean as a whale sanctuary.
Institute of Tropical Forestry
For the past 53 years the Institute has researched extensively on ecology, soil, water and ecosystem management, and trained foresters and forestry technicians in Caribbean and Latin American countries.
The institute has also reforested thoUnited States of Americands of hectares in the mountainous Luquillo experimental forest, contributing to its rehabilitation.
Currently the institute is collaborating with the Brazilian Government in the development of a research and forest management program in the Tapajos National Forest in the Brazilian Amazon.
