Abstract Climate change can affect all aspects of the tick life cycle, from altering host distributions to modulating tick development and survival. This expert opinion focuses on how humans can greatly affect tick populations via livestock management. This is likely to occur through at least three pathways: (i) by altering host abundance and composition; (ii) via habitat modification due to grazing and trampling; and (iii) by altering tick mortality via tick-control methods. Thus, climate-driven changes to livestock management can profoundly alter tick populations, especially in regions such as eastern and southern Africa, where high livestock density and worsening climate changes are coupled with high tick diversity and abundance.

This chapter emphasises that audio-visual (AV) resources are very fragile and need to be stored in ideal conditions to preserve them for posterity. It describes different types of AV materials and the conditions under which they should be kept. It is based on a study that was conducted in the Eastern and Southern Africa Regional Branch of the International Council on Archives (ESARBICA) region. Data were gathered using quantitative and qualitative methods. The results revealed lack of equipment to monitor environmental conditions, absence of policies to govern the acquisition, appraisal, access, preservation, retention, digitisation and disposal of AV materials, and failure to apply the records life cycle (or any model) to AV records. The results point to a need for national archives to develop guidelines that apply to AV materials particularly in Africa. Particular attention should be given to training AV archivists in the region using an integrated curriculum.

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.
