Book (series)Global guidelines for the restoration of degraded forests and landscapes in drylands 2015Drylands cover nearly half of the earth’s land surface and are home to one-third of the global population. They face extraordinary challenges, including those posed by desertification, biodiversity loss, poverty, food insecurity and climate change. Up to 20 percent of the world’s drylands are degraded, and people living there are often locked into a vicious circle of poverty, unsustainable practices and environmental degradation. It is clear that serious efforts are needed to arrest dryland degr adation and restore degraded lands, and the simple but urgent aim of these guidelines is to support such efforts It is the first time that global guidelines on dryland restoration are made available. These guidelines target two main groups – policymakers and other decision-makers, and practitioners – because both have the power to bring about positive change. While they should be tailored to suit regional and local contexts, they present the essential components for the design, implementation an d sustainability of restoration initiatives that can help build ecological and social resilience and generate benefits for local livelihoods. As illustrated by the rich case studies provided, the guidelines involve a vast range of actions, from on-the-ground activities such as habitat protection, assisted natural regeneration, sand-dune stabilization and planting, to policy improvements, provision of financial incentives, capacity development, and continuous monitoring and learning. Moreover, th ey show that restoration needs to be considered across the entire market value chain, from seed to end-product, as well as at the landscape level, including the mosaic of land uses, needs and expectations of interest groups.

ArticleValidating viability of Melia volkensii seeds stored as extracted seeds or nuts for production of high-quality germplasm in domestication and conservation of dryland tree species

No results found.Development and supply of superior germplasm is important for the promotion of tree planting. Kenya has lost many tree seed sources through deforestation, land degradation, forests encroachment and conversion of agricultural land to housing. Nevertheless, limited access to tree seeds of high quality is the major constraint to sustainable tree production in Kenya and proper information on storability of extracted seeds is lacking. Melia volkensii trees species is highly valued in drylands of Kenya for tremendous roles in social-economic, ecological and environmental protection, and conservation. This experiment aims at determining viability test of Melia seeds stored as nut over period of one year and the resultant effect that they will have on seed germination. Furthermore, the research investigates the conducive environment that would favor storage of Melia seeds in order to improve its viability status. The experiment showed that Melia seeds stored at room temperature and a temperature of 4 degrees centigrade had higher germination capacities compared to Melia seeds stored at a temperature of -20 degrees centigrade. The peak average germination speed was 2.11 with a germination value of 3.99. Significant (p value ≤ 0.001) differences were observed in the germination capacities between Melia stored as seeds and nuts for the first, second, third, fourth, fifth, sixth and seventh germinations (p value ≤ 0.05). From the study, Melia stored as seeds at a temperature of 4 degrees centigrade had the highest marginal germination capacity. This study provides the best information for storage and handling of Melia seeds in maintaining its viability.
