Northern settlement family-style: labor planning and population policy in Noril'sk

This paper reviews labor planning and population policies in Noril'sk, a mining and metallurgical settlement in northern Siberia. When the settlement was established in 1935, planners were lacking in ideas about how to recruit workers to staff the mines and smelters and how to retain the labor force once it was in place. From 1935-79, planners followed a forced labor policy dependent upon the labor of prisoners. However, this solution was not adequate for meeting the manpower needs of an economy undergoing rapid technological sophistication. Northern wage increments were introduced after 1945 to recruit skilled workers from other regions. These increments built up over a 4-year period to a maximum of 80% of base pay. A special cost of living bonus was also awarded. Although these inducements facilitated labor recruitment, labor retention remained a major problem. Surveys indicated that workers would prefer improvements in housing and social services to further wage increases. Thus, policy was directed at the housing shortages, poor medical care, and inadequate child care facilities in Noril'sk. Such improvements facilitated labor retention but also contributed to overpopulation. The population doubled between 1956-80, exceeding 180,000 in the latter year. In the early 1980s, selective measures toward population control were implemented to ensure maintenance of living standards (e.g., encouragement of older workers to leave the area upon retirement, more careful screening of recruits). The goal is to stabilize city size at around 250,000. The Noril'sk case illustrates that quality of life investments can alleviate labor retention problems even in the harshest physical environments. Recent policies have advocated productivity-enriching technologies that do not require increments in the labor force.

Honduras: Caribbean Coast

The coast of Honduras, Central America, represents the southern end of the Mesoamerican Barrier Reef System, although its marine resources are less extensive and studied than nearby Belize and Mexico. However, the coastal zone contains mainland reef formations, mangroves, wetlands, seagrass beds and extensive fringing reefs around its offshore islands, and has a key role in the economy of the country. Like most tropical areas, this complex of benthic habitats experiences limited annual variation in climatic and oceanographic conditions but seasonal and occasional conditions, particularly coral bleaching and hurricanes, are important influences. The effects of stochastic factors on the country's coral reefs were clearly demonstrated during 1998 when Honduras experienced a major hurricane and bleaching event. Any natural or anthropogenic impacts on reef health will inevitably affect other countries in Latin America, and vice versa, since the marine resources are linked via currents and the functioning of the system transcends political boundaries. Much further work on, for example, movement of larvae and transfer of pollutants is required to delineate the full extent of these links.

Anthropogenic impacts, largely driven by the increasing population and proportion of people living in coastal areas, are numerous and include key factors such as agricultural run-off, over-fishing, urban and industrial pollution (particularly sewage) and infrastructure development. Many of these threats act synergistically and, for example, poor watershed management via shifting cultivation, increases sedimentation and pesticide run-off onto coral reefs, which increases stress to corals already affected by decreasing water quality and coral bleaching. Threats from agriculture and fishing are particularly significant because of the size of both industries. The desire to generate urgently required revenue within Honduras has also led to increased tourism which provides an over-arching stress to marine resources since most tourists spend time in the coastal zone. Hence the last decade has seen a dramatic increase in coastal development, a greater requirement for sewage treatment and more demand for freshwater, particularly in the Bay Islands.

Although coastal zone management is relatively recent in Honduras, it is gaining momentum from both large-scale initiatives, such as the Ministry of Tourism's ‘Bay Islands Environmental Management Project', and national and international NGO projects. For example, a series of marine protected areas and legislative regulations have been established, but management capacity, enforcement and monitoring are limited by funding, expertise and training. Existing and future initiatives, supported by increased political will and environmental awareness of stakeholders, are vital for the long-term economic development of the country.
