As regards the substitution of MB, the objectives of German Development Cooperation reflect GTZ guidelines which include:
GTZ takes a special interest in phasing out MB because of its extraordinarily high ozone-depleting potential. A further reason for GTZ's commitment in this field is the acute and chronic health hazards. It should be noted that some of the alternatives listed in chapter 3 involve similar health hazards. This is the major reason why GTZ does not favour the use of chemicals as alternatives for soil treatments (cf. 3.1.1 and 3.1.5) or of certain fumigants for commodities and structures (cf. 3.2.2, 3.3.10 and 3.4.2).
The statements and recommendations in this brochure are in line with the MP, Agenda 21 and the BMZ's political priorities.
In some instances, however, because of the urgent need to implement measures to conserve our global environment and introduce sustainable solutions for agricultural, post-harvest and quarantine problems, the recommendations go beyond the decisions of the parties to the MP. This applies especially to the smart use of the grace period for A5 countries that extends until the year 2015. This grace period has advantages as it provides additional time to implement sound alternatives but it may also bring about severe new problems that led many A5 countries to express concern about it:
In this brochure, alternatives and recommendations are included that relate to quarantine and pre-shipment uses. This is meant as a contribution to the further discussion of MB uses that are currently not controlled by the MP and to its complete substitution in the future.
