As per my experience as a pesticide toxicologist with the international code of conduct for pesticides and my long observation about pesticides and fertilizer pollution I like to add my general comment: what I have observed during decades of experience all these global laws and regulations are more or less good and correct but the big problem is enforcement in the level of farmers in particular in developing countries. This is a main obstacle and need lots of work, capacity and culture making for farmers in developing countries with ever increasing demand for food toward 2050 with 2 million more people on the planet.
