Absolutely and undoubtedly.

I don't think so, those nations advanced in agriculture have held unto their traditional agricultural practices and unproved on them innovatively unlike other nations who blindly copied other nations by using their pesticides and fertilizers which may not even address the root course of the challenges they face on their agricultural lands.

This may be partially true. In the time that developing countries are using different pesticides even prohibited ones because of its strong effects, developed countries are using less harmful pesticides but difinatly more in the types and amounts. The issue here i belive is about harmful effects both on environment and human health not nessarliy about the amount.

Tricky questions, ones may rush and say yes, but the answer is more complicated. If we look in term of pesticides uses per capita, nations that are advances in agriculture used far more pesticides than developing countries. Based on this, we could argue that they indeed contribute more to pollution. However, we have to keep in mind that, i) there are lot of prohibited pesticides used in less advance countries, ii) the use of pesticides in these countries is often inappropriate, with an overuse for instance, and a poor disposal of waste. If we look onto it from this perspectives, one will say less advances countries in Agriculture contribute more to pesticides pollution. But again this is not necessarily true. So to conclude, I will say there is not a yes or no answer to this question as the appropriate answer is probably country specific.

La comparaison des statistiques relatives à l'utilisation des engrais et des pesticides dans les pays développés et en voie de développement montre bien que les pays développés utilisent ces intrants de manière beaucoup plus intensive

que dans les pays en développement

I don't think so, many developing countries are using pesticide products in large quantities and these pesticides are unsafe to environment and health. I think biopesticides could be a safe solution for this problem.

J'apporte une réponse très nuancée. (i) D'abord vu la différence des dégrés d'intensification et de surfaces emblavées, à mon sens la comparaison sous la seule observation des consommations par hectare semble être insuffissante pour incrimer un groupe. (ii) Au regard du graphique, j'ai de quoi m'intérrogé sur les données utilisées d'autant plus que la vente et même l'application de ces produits phytosanitaires souffrent d'insufissance cruelle de réglementation et de contrôle dans la plupart des pays en développement. (iii) Je ne suis pas sûr que les concentrations retrouvées aussi bien dans l'air, les résidus et les eaux (de surface et souterraines) soient systématiquement plus élevées dans les "pays dévelopés".

the type of the pesticides is what counts. May be the amount is big by the type of pesticide is safer and vise versa.
