The relationship between tail biting in pigs, docking procedure and other management practices

The tail length (docked, tipped or undocked) and tail status (bitten or unbitten) of 27,870 pigs from 450 units was recorded at six UK abattoirs. A farm survey of the final finishing stage was used to investigate the relationship between management practice and tail biting. This showed that docking was the most important factor influencing the probability of being not bitten, with 2.4% of docked and 8.5% of long-tailed pigs being tail-bitten. The following factors reduced the probability of long-tailed pigs being tail-bitten; light straw provision, use of natural ventilation or artificially controlled natural ventilation (ACNV), mixed sex grouping, meal or liquid feeding, and use of double or multi-space feeders. Docked and long-tailed pigs provided with light straw and natural ventilation/ACNV had levels of tail biting of 1.2% and 4.3% respectively; 3.9% of docked pigs with artificial ventilation and no straw were tail-bitten. Long-tailed pigs fed via double or multi-space feeders also had 3.9% of tails bitten.     

Right to food; right to feed; right to be fed. The intersection of women's rights and the right to food

This paper explores conceptual and practical linkages between women and food, and argues that food security cannot be realized until women are centrally included in policy discussions about food. Women's special relationship with food is culturally constructed and not a natural division of labor. Women's identity and sense of self is often based on their ability to feed their families and others; food insecurity denies them this right. Thus the interpretation of food as a human right requires that food issues be analyzed from a gender perspective. For example, the paper asks how the rights to food intersect with the rights of women and other human rights; what the policy implications of these intersecting rights are; and how their integration will contribute to the effort to view all human rights as mutually reinforcing, universal, and indivisible. The second half of the paper speculates on the significance of distinctions between the right to be fed, the right to food, and the right to feed for understanding the relation between gender and food.     

Making agricultural landscapes more sustainable for freshwater biodiversity: a case study from southern England

• 1. Agriculture is known to have a range of deleterious impacts on freshwater habitats and biota and many countries have introduced measures to attempt to mitigate these impacts through agri‐environment initiatives. Despite the protection they provide, water bodies (any discrete body of surface fresh water) in farmland landscapes commonly remain impaired by agriculture. In some areas of the UK there have been calls to halt farming completely, indicating that the measures offered for the widespread protection of aquatic systems, particularly the use of buffer strips, may not be extensive enough to provide sufficient protection for freshwater biota.
• 2. This study investigated whether existing agri‐environment measures for the widespread protection of aquatic habitats could be better deployed to provide a higher level of protection for the aquatic macrophytes and macroinvertebrates of a study area in southern England.
• 3. Reserve selection procedures were used to reallocate the area of land that could be remunerated under the Environmental Stewardship scheme as buffer strips bordering water bodies, so that a higher level of protection was provided for both the richness and rarity of aquatic species in the study area.
• 4. Almost 395 ha were available for reallocation in the reserve selection process, which was found to provide a satisfactory level of protection for up to 90% of the surveyed species.
• 5. The results showed that the agri‐environment scheme in England has a great deal of potential to provide more effective protection for the aquatic biodiversity of agricultural landscapes if measures are targeted.
