What have been the impacts of the GGDP-generated maize technologies? In the absence of reliable baseline data, it was not possible to calculate quantitative measures of project impact. Based on farmers’ qualitative judgments, however, it is clear that adoption of the GGDP-generated technologies has been associated with significant farm-level productivity gains (measured in terms of maize yields) and noticeable increases in the income earned from sales of maize. Impacts on the nutritional status of rural households, however, appear to have been less pronounced. Even though the latest MVs have been extensively promoted for their improved nutritional status, relatively few of the survey respondents were aware. | The project for sustainable water use in chemical paper textile and food industries New technologies or innovative treatment lines for reliable water treatment for P P and minimization of waste production Authors S.

In the Pulp Paper industry a lot of effort is put into to water saving and closing water circuits also reducing substantially the environmental impact both by process modelling and Kidney technologies as internal process water treatment. However a number of problems around the removal of substances are not solved yet and further closing of the water cycle causes other problems. Challenges for water re-use in the Pulp Paper industry are the following - The elimination of residual soluble COD and BOD which can both affect the production process and the paper quality - The removal of sticky solids and suspended solids which can induce plugging of pipes and showers deposit formation abrasion loss of tensile strength - The treatment of concentrate streams containing calcium sulphate chloride and organics which can lead to salt accumulation in case of water loop closure corrosion scaling of pipes and showers in the paper production
