Mauritania’s coastal waters are among the world’s richest fishing grounds. However, just as in many other countries around the globe, the sustainable use of this resource is under threat from illegal fishing and overfishing. KfW contributes to protecting the valuable fishing grounds with the aid of modern surveillance systems and rigorous conservation and species protection measures.

During the last few years, the donor community has increased its efforts to reduce the large amounts of fish lost in the distribution chain in artisanal fishery, an endeavour that ought to be welcomed in principle. However, focusing on one single solution, the development of an expensive cool chain and the supply of fresh or frozen fish, represents a massive interference with the traditional processing and distribution channels, with women being the main losers. Our author calls for more foresight in international co-operation.

Experts agree that the rising demand for fish for human consumption cannot be met without a major expansion and sustainable intensification of aquaculture. Our WorldFish authors describe the areas in which research plays a particularly important role in this context.

Riparian ecosystems are valuable to the ecological and human communities that depend on them. Over the past century, they have been subject to shifting management practices to maximize human use and ecosystem services, creating a complex relationship between water policy, management, and the natural ecosystem. This has necessitated research on the spatial and temporal dynamics of riparian vegetation change. The San Acacia Reach of the Middle Rio Grande has experienced multiple management and river flow fluctuations, resulting in threats to its riparian and aquatic ecosystems.

Matters of environmental migration are frequently looked at from a humanitarian perspective.1 This policy brief will instead look at it with a lens focusing on land issues. The question of environmental migration is inevitably linked to the question of land for several reasons. First, climate and environmental change trigger and accelerate the loss of land due to sea-level rise, coastal erosion, landslides and other forms of land degradation.

The promulgation of the Kenyan Constitution 2010 brought into place concerns about the urgency for land reform. Land reforms hold the key to solving some of Kenya’s greatest challenges such as landlessness, community cohesion, food security and sustainable development. Land reforms lie at the heart of the work of the National Land Commission (NLC) and Kituo cha Sheria and they are also at the heart of many Kenyan communities who live, work and rely on land. Information contained in the book goes a long way in educating these communities about their land rights.

Transformation or modification of vegetation distribution and structure in arid riparian ecosystems can lead to the loss of ecological function. Mexico has 101,500,000 ha of arid lands, however there is a general lack of information regarding how arid riparian ecosystems are being modified.
