L'application du principe du pollueur-payeur à la gestion du risque environnemental et à la mutualisation des coûts de la pollution

Le but de cette étude est de déterminer qui paie pour le risque de pollution et par conséquent de vérifier si le principe du pollueur-payeur est effectivement mis en œuvre dans le domaine de la gestion du risque environnemental. Il s’agit d’examiner le degré de mutualisation de la gestion du risque dans différentes législations particulière. Les payeurs peuvent a priori se classer dans quatre catégories : les personnes dont l’activité contribue au risque de pollution, les compagnies d’assurance qui acceptent d’assurer ces personnes, les organismes ou autorités publics et les tiers. Divers exemples issus de la législation belge ou européenne seront examinés afin de déterminer s’ils sont conformes à la lettre et/ou à l’esprit du principe pollueur-payeur. Il s’agit notamment de la responsabilité civile, de la responsabilité environnementale, de la gestion des déchets et du marché de quotas d’émissions de gaz à effet de serre. Les techniques de responsabilité qui interviennent après que le dommage ait lieu et requièrent la démonstration de l’existence d’un lien de causalité ne permettent pas toujours d’assurer pleinement la fonction préventive du principe du pollueur-payeur. Elles ne constituent pas des instruments adéquats de gestion de la pollution diffuse ou chronique. En conséquence, des techniques de mutualisation de la gestion du risque environnemental se sont développées. Le recours à ces techniques de mutualisation (par le recours à l’assurance, aux fonds publics financés par la fiscalité environnementale ou aux marchés de droit d’émissions) est-il conforme au principe pollueur-payeur et permet-il d’atteindre l’objectif d’un niveau élevé de protection de l’environnement ? L’effet dissuasif du principe pollueur-payeur n’est-il pas amoindri par la mutualisation ? L’article montre que la définition du principe pollueur-payeur par la Cour de Justice de l’Union européenne est centrée sur la contribution au risque de pollution ce qui permet de recourir aux techniques de mutualisation de la gestion du risque tout en respectant le Traité sur le fonctionnement de l’Union européenne. 

Securing Tenure for Sustainable Livelihoods: A Case of Women Land Ownership in Anglophone Cameroon

The majority of women in Third World countries depend on land for their livelihood. Security of tenure is important for them to ensure sustainable development, especially in rural areas. In most parts of Africa, land ownership is affected by traditional values, inheritance rights, and government influence. These forces have provided varying types of tenure which are detrimental to the women in rural and urban areas. Land acquisition and its development has been an emotive issue due to traditional pressures and the law as regards the process of land certification. The government and traditional administrations are highly involved in the way women own land and subsequently develop it in Anglophone Cameroon. State authority over land acquisition is important, but the process for obtaining land title is herculean especially for the rural woman. This study illustrates that land acquisition and development by women constitute a problem because of traditional pressures and the law guiding the process of land certification. There is need to exhume the barriers of government’s legal instrument (The Land Consultative Board) that regulates the ownership of land and to revisit some traditional practices as regards land ownership that impact negatively on women in a changing and globalizing world. A compromise approach is advocated for land acquisition that can transcend traditional barriers as well as render the process of land registration more realistic especially for women.

Coral Reef Ecosystem of Lakshadweep Archipelago –A Biogeochemical Facsimile

The present study focuses on the biochemical aspects of six islands belonging to Lakshadweep Archipelago – namely Kavaratti, Kadamath, Kiltan, Androth, Agathy and Minicoy. Lakshadweep, which is an area biologically significant due to isolation from the major coastline, remains as one of the least studied areas in Indian Ocean. The work, processed out the distributional pattern of trace metals among the biotic (corols, sea weeds and sea grass) and abiotic component (sediments) of ecosystem. An effort is made to picturise the spatial distribution pattern of different forms of nitrogen and phosphorus in the various sedimentary environments of the study area. Studies on the biogeochemical and nutrient aspects of the concerned study area scanty. In Lakshadweep, the local life is very dependent on reefs and its resources. The important stress which produce a threatening effort on the existence for coral reefs are anthropogenic-namely-organic and inorganic pollution from sewage, agricultural and industrial waters, sediment damage from excessive land cleaning, and over exploitation particularly through destructive fishing methods. In addition these one other more localized or less service anthropogenic stress: pollution by oil and other hydrocarbons, complex organic molecular and heavy metal pollution, and destructive engineering practices.

Economic Impacts Of Air Pollution on Human Health and Property Values

The objectives of the present study are to provide a systematic descriptive documentation of the nature of air pollution of the Cochin industrial agglomeration, estimate the willingness to pay for morbidity reduction due to air pollution in observed and hypothetical markets and to estimate the value of welfare loss in the purchase of property due to reduced air quality. This study is an attempt to examine economic impacts of air pollution on the human health and property values in the industrial capital of Kerala. The process of industrialization in Kerala and the increase in air pollution created damages to human, natural and economic resources in the state. The study documents the extent of air pollution and applied econometric approaches to estimate economic impacts of air pollution on human health and property values. The Important sources of air pollution identified in Cochin are emissions from industries and automobiles.

Distribution of Benthic In fauna in the Cochin Backwaters In Relation To Environmental Parameters

The study revealed stress and localized impact of industrial waste on the biota, predominance of stress tolerant species and low diversity in the vicinity of the effluent discharge point. These studies on impact of environmental parameters on the distribution of macrobenthos thus indicate the quantum of endurance warranted by the infauna to tide over the wide range of environmental stress. Low diversity and lower number of benthic fauna near discharge site can be attributed to the stress caused by cumulative toxic effects of effluents. The results of the physico-chemical parameters highlight the effects of pollution. The results of the study indicated the changes due to the large-scale movements of the estuarine water under the influence of tide, monsoon and land runoff coupled with its heterogenous nature owing to the effluent discharge from the industries

Dynamics of Land Use in Recently Settled Forest Areas: a Case Study of Attappady , Kerala

The present study on the dynamics of land use in recently settled forest areas. In the course of events, tribals lost their land; the demographic structure of Attappady changed; the cropping pattern got diversified; traditional techniques of production were ruined; new crops and new techniques of cultivation came to stay; and the entire cost and return structure of production underwent radical change. Migration to Attappady is essentially a continuation of the Malabar migration process from Travancore, through, some people from Tamil Nadu also had migrated to this region earlier. The demographic structure, along with land structure, has changed in favour of the settlers within a short span of time. Lack of security of ownership has acted as a strong reason for wanton exploitation of land resources. The major influencing factors on crop choices among settlers were labour endowment, date of settlement and education. Attappady is an unique ecosystem in Kerala characterized by many interdependables. The latest hand of environmental degradation is a grave danger especially on sloppy terrains,which are under cultivation of tapioca and dry annual crops like groundnuts, cotton, grams etc. Soil erosion as a result of the unplanned cultivation of these crops has resulted in dramatic decline in soil fertility and hence low crop productivity. This calls for a watershed management approach for the sustainable development of the region. A progressive agrarian transformation is warranted to maintain the homegarden as a sustainable production system in ecological and socio-economic terms.
