Titre : Impact of pesticides on farmer health and the rice environment : An overview of results from a multidisciplinary study in the Philippines Type de document : texte imprimé Auteurs : P.L. Pingali, Auteur Année de publication : 1995 Importance : p 3-21 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : PHILIPPINES UTILISATION DES PESTICIDES IMPACT DES PESTICIDES AGRICULTEURS RIZIERES Résumé : Pesticides continue to be a significant and growing component of modern rice technology and its relative importance has increased despite the availability of alternatives to exclusive chemical pest control such as varietal resistance and integrated pest management (IPM). This chapter provides an overview of a multidisciplinary scientific effort to identify the incidence and magnitude of on-site and off-site environmental effects of pesticide use. The main idea of this study is that the negative human health impact of pesticides is large and overwhelms their impact on the paddy ecosystem and the environment. Somewhere pesticide use is small in terms of dosages and number of applications and the chemicals used degrade in tropical flooded conditions than in the temperate upland conditions. At the end, this study envisions high rates of return to research on nonchemical pest control methods such as varietal resistance to pest that can be embodied in seeds or the use of enemies and other biological controls.

Pingali, Auteur Importance : p 343-360 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : PHILIPPINES IMPACT DES PESTICIDES SANTE DES AGRICULTEURS ANALYSE ECONOMIQUE ANALYSE MEDICALE Résumé : Prolonged exposure to pesticides can lead to cardiopulmonary disorders, neurological and hermatological symptoms and skin disease. These symptoms can lower productivity because of the farmers absence from work during treatment and recuperation and impaired capacity to work. Farmers who don’t know about the harmful effects of pesticides sometimes overvalue their benefits and use them beyond the private and social optimum levels.
In this unique study, an economist and a medical doctor assessed the impact of a prolonged pesticide use on farmer health. The study objectives wete to identify the types of health impairments caused by long-term pesticide use and to quantify the impairment relative to the level of pesticide use. Detailed medical examinations showed that pesticide users exhibited symptoms of longterm exposure to hazardous chemicals. Econometric analysis showed that the magnitude of chronic health costs were related to pesticide exposure. When health effects were accounted for, the net benefits of insecticide use were negative.

The functionality of this aquatic community depends on the relative and absolute population densities of the various gropus and their activity rates. The widespread introduction of chemical pesticides to control rice pests has increased grain yields, however , because pesticides are often unspecific, they have the potential to pdify the soil-floodwater communities of wetland ricefields. It is important to understand and predict how pesticide use affects the ecology of the ecosystem and to consider the implication of these changes for rice production and rice-producing environments.

Titre : The impact of pesticides on ricefield vertebrates with emphasis on fish Type de document : texte imprimé Auteurs : A.G. Cagauan, Auteur Importance : p 203-248 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : IMPACT DES PESTICIDES UTILISATION DES PESTICIDES RIZIERE METHODOLOGIE D'EVALUATION ANALYSE DES RESIDUS DES PESTICIDES INSECTICIDES Résumé : Production of fish on rice farms in Asian countries is considered by policymakers as a viable option for sustaining food production in lowland areas, augmenting farm income and improving the quality of food available to asian farm housholds. Rice-fish farming systems hence represent an ideal practice for more efficient utilization of agricultural resources in lowland rice areas.
The use of pesticides has been reported to have caused a decline in the practice of rice-fish culture in some parts of Central Thailand. Annual application of around 2kg per hectare of insecticide was reported to have caused financial losses in rice-fish culture in Indonesia.
Rice-fish farming in the Philippines was introduced only in 1974 and is still at the experimental (field-testing and verification) stage. Its small-scale adoption is influenced by technological and social constraints such as the use of high-yielding varieties associated with indiscriminate use of pesticides and shorter rice production cycle resulting in smaller fish size at harvest, unavailability of fingerlings, inadequate water supply, fish poaching and the risk-averse attitude of most rice farmers.
The two main constraints to increased productivity in irrigated rice-fish farming systems however, are water control and pesticide use. The latter is considered the more serious constraint because it can be justified in areas where potential rice yields are also high.
Since fish must adapt to management practices for rice, information on toxicity, degradation and residues of pesticides in fish are imerative for the development of a better symbiotic relationship between rice and fish in an integrated farming system. Acute toxicity parameter LC50² provides information on the effect of pesticides in extreme conditions and may serve as a basis for field application rates safe for fish. Degradation period of pesticides meanwhile indicate the safe period to stock fish. Pesticide residue data in fish are few but remain essential for the safe use of pesticides in rice-fish culture. These information are presented and reviewed in Cagauan and Arce and will be used in subsequent discussions.Numéro du document : A 6290/H00 366 Niveau Bibliographique : 2 Bull1 (Theme principale) : FORESTERIE Bull2 (Theme secondaire) : GENIE FORESTIER The impact of pesticides on ricefield vertebrates with emphasis on fish [texte imprimé] / A.G.

In the Philippines, some farmers reported detrimental effects of pesticides to fish, but no data is available to substantiate such claims. While potentials include good financial incentives, constraints range from lack of inputs and demand for fish to heavy use of agrochemicals especially pesticides.

So this paper presents an approach that integrates aspects of the health and education literatures to study the farm productivity effects and the health effects associated with on-farm pesticide use. This approach was implemented in a unique study of rice production and farmer health in two regions of the Philippines. Production data from a farm – level survey were integrated with health data collected from the same population of farmers to measure the impacts of pesticide use on farmer health and the impacts of farmer health on productivity. These relationships were then used in a simulation analysis to investigate the health and productivity tradeoffs implied by a policy to restrict pesticide use.
The study focuses on two aspects of pesticide productivity : the conventional , direct effect of pesticides used as a production input to control pests and an indirect human health effect, operating through the chronic effects that pesticide exposure has on farmer’s health and the effects that farmer’shas on farm productivity.
The empirical approach deveveloped in this paper is based on a three-step procedure : the first one involves the construction of a variable measuring health impairment, based on data generated by clinical examinations of a subset of farmers in the production survey. The second step of the analysis is to include the estimated health impairment variable as an explanatory variable in a cost function to estimate the productivity of pesticides and the productivity effects of health impairment. The last one is to use the results from the first two steps in a policy simulation in which the production and health relationships that were estimated are simulated.Numéro du document : A 6290/H00 366 Niveau Bibliographique : 2 Bull1 (Theme principale) : PROTECTION DES VEGETAUX Bull2 (Theme secondaire) : PROTECTION DES VEGETAUX-CONSIDERATIONS GENERALES Pesticides, productivity and farmer health : a Philippine case study [texte imprimé] / J.M.
