Extractive Reserves

SUMMARYExtractive reserves are conservation units that are concurrently expected to sustain subsistence and cash economies of reserve residents, often through use of non-timber forest products (NTFPs). Brazil nut (Bertholletia excelsa) has been central to many Amazonian reserves and resident livelihoods therein, due to its basin-wide distribution, significance in global markets, and potential for sustainable use and forest conservation. Yet, do the benefits of this and other NTFPs extend to all extractive reserve residents? A livelihood survey, structured interviews, and Brazil nut inventories from 2008 to 2010, randomly sampling the widely dispersed households and corresponding forests across the three regions of Riozinho do Anfrísio Extractive Reserve (RDAER), revealed significant social and ecological heterogeneity among RDAER regions. There were differences in Brazil nut stand access, individual tree characteristics (including crown form and marginally, and fruit production), stand and tree management, multiple household characteristics that shape resident investment and dependence on NTFPs, and the contribution of Brazil nut to forest-based income. If Brazil nut and other NTFPs are to reconcile conservation and development in forest communities, then policies to regulate and promote NTFP use must integrate the socioecological heterogeneity inherent in these forest products and within reserve polygons.

Multiple Health

Nuts hold prime significance throughout the world as they offer multiple health benefits owing to their highly nutritious profile. A number of scientific studies have demonstrated their actions against inflammation, oxidative damage, the aging process, as well as dementia or memory loss. However, only walnuts, followed by almonds, hazelnuts and pistachios, have shown promising results in empirical studies for memory improvements. So, the current review focuses on presenting hypotheses regarding anti-dementia property of nine different nuts: almond, walnut, pistachio, Brazil nut, peanut, pecans, cashew, hazelnut, and chestnut. The nutritious profile of nuts contains essential fats (mostly mono- and poly-unsaturated fatty acids), proteins (source for arginine, lysine and tryptophan), vitamins (riboflavin, folate, and various tocopherols), fibers, minerals (calcium, sodium, magnesium, phosphorus and potassium) and trace elements (copper, zinc, and selenium). Interestingly, the constituents of natural products, nuts being an excellent example, work synergistically and/or in a side-effect neutralizing manner. These latter properties can make nuts an alternate therapy for humankind to fight against memory loss.

Sustainable development is among the foremost ideas that guide societal aspirations around the world. This book interrogates the concept through a critical lens, examining both its history and the trajectory of its manifestations in the Brazilian Amazon. The book argues that sustainable development is a concept that is better understood as involving embroilments and ongoing processes of contestation rather than a single end goal. The research offers historical analysis of Amazonian development from the colonial era into the discourse and praxis of sustainable development in contemporary times, and then illustrates the tensions of sustainable development plans that are experienced by people living in the areas geographically the closest to where those plans are being implemented. The history of the Brazilian Amazon is introduced to readers through focused discussions on the tensions between making grand plans for the region and the everyday practices and experiences of sustainable development, which involve considerably more muddling. Case studies explore agrarian reform initiatives that occur alongside road paving projects, the creation of extractive reserves and conservation areas that follow in the wake of assassinations, and the construction of a massive hydroelectric dam. While Amazonian sustainable development is a widely-accepted imperative, the research presented here shows how land use and infrastructure plans conducted in the name of sustainable development often perpetuate and reinforce economic and political inequalities.

During seed germination, desiccation tolerance is lost in the radicle with progressing radicle protrusion and seedling establishment. This process is accompanied by comprehensive changes in the metabolome and proteome. Germination of Arabidopsis seeds was investigated over 72 h with special focus on the heat-stable proteome including late embryogenesis abundant (LEA) proteins together with changes in primary metabolites. Six metabolites in dry seeds known to be important for seed longevity decreased during germination and seedling establishment, while all other metabolites increased simultaneously with activation of growth and development. Thermo-stable proteins were associated with a multitude of biological processes. In the heat-stable proteome, a relatively similar proportion of fully ordered and fully intrinsically disordered proteins (IDP) was discovered. Highly disordered proteins were found to be associated with functional categories development, protein, RNA and stress. As expected, the majority of LEA proteins decreased during germination and seedling establishment. However, four germination-specific dehydrins were identified, not present in dry seeds. A network analysis of proteins, metabolites and amino acids generated during the course of germination revealed a highly connected LEA protein network.
