“…Today Baja California Sur's more than 2000 km of coastline supports a diverse fishery (Robadue 2002, Enriquez-Andrade et al 2005). In the area surrounding La Paz, smallscale fishers targeted 55 taxa in 2010.…”

Many fisheries stocks and the livelihoods of those who make their living from fishing are in decline, and these declines are exacerbated by uncertainties associated with increased climate variability and change. Social scientists have long documented the importance of mobility and diversification in reducing the risk and uncertainty associated with climate variability, particularly in the context of small-scale fishing. However, it is unclear how these traditional mechanisms are buffering fishers against the varied stressors they currently face, including those associated with environmental variability. This paper examines how fishers on the southern gulf coast of the Mexican state of Baja California Sur perceive and respond to stressors associated with normal environmental variability, how their ability to adapt is spatially distributed, and what threats they perceive to their continued ability to adapt. Understanding the adaptation strategies and everyday vulnerabilities that fishers face can elucidate problems associated with current fisheries management and the underlying factors that cause vulnerability, and also help decision makers, including fishers themselves, develop more effective adaptation strategies in the face of climate change.

“…Conservation of the diverse ecosystems in the Gulf of California is being provided by several marine biosphere reserves, marine protected areas (for natural resources or flora and fauna), marine sanctuaries, and national marine parks (Cartron et al, 2005;Enriquez-Andrade et al, 2005;Lluch-Cota et al, 2007;Danemann and Ezcurra, 2008;Brusca, 2010;Norris, 2014). The current protected areas of the Gulf of California include 244 islands, islets, and coastal areas indicated on the World Heritage List "Islands and Protected Areas of the Gulf of California" (UNESCO, 2011(UNESCO, , 2013(UNESCO, , 2016 and "Ficha Técnica para la evaluación de los sitios prioritarios para la conservación de los ambientes costeros y oceánicos de México" (CONABIO et al, n.d.;Sánchez-Ibarra et al, 2013).…”

In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: s m i t h s o n i a n c o n t r i b u t i o n s t o b o t a n y • n u m b e r 1 0 6

“…Their ecosystems perform key ecological functions (nutrient cycling, critical habitats, offspring dispersal, recruitment, nursery and breeding sites) and provide important ecosystem services (fisheries biomass, climate stability, leisure, tourism, food production) (Álvarez-Romero et al 2013;Carmona and Danemann 1997;Costanza et al 1997;de Groot et al 2002;Enríquez-Andrade et al 2005;Kremen 2005;Liu et al 2010). Specifically, the predominance of Ruppia maritima associated with coastal water bodies on the Gulf coast and of Zostera marina associated with coastal water bodies on the Pacific coast (Ramírez-García and Lot 1994;Riosmena-Rodríguez et al 2009;Ward et al 2004) are worth highlighting as a biological expression of the differences between the Gulf and the Pacific areas.…”

An examination of coastal conservation by remote sensing in Baja California Sur, México

et al. 2015

The state of Baja California Sur (BCS), Mexico, has a coastline of 2131 km with eight Protected Natural Areas (PNA) (33,075 km 2 ) mainly located in the coastal zone. Here, we (1) review the current status of the diversity and distribution of coastal ecosystems in BCS, (2) assess the composition and coverage of these ecosystems in PNAs, and (3) identify coastal ecosystems of special interest for conservation. The combination of spatial analysis techniques was carried out using LandSat TM images and GIS processing, considering ecoregions and ecosystems in the coastal zone, as well as through the application of an ecosystem diversity index. In the BCS coastal zone, 11 ecosystems were identified: scrub, coastal water body, riparian, bare soil, halophyte, beach, salt flat, mangrove, salt marsh, coral reef, and seagrass. The ecosystem diversity in BCS results from the coastal features that differentiate the Pacific and the Gulf coasts. PNAs include 17 % of coastal ecosystems. Bahia Magdalena (Pacific) and Bahia Concepción (Gulf of California), which are key for conservation (including mangroves and seagrasses), should be considered either for classification as PNAs or for inclusion in coastal management programs. The combination of remote sensing and GIS with biogeographic and ecosystemic approaches in our study enabled to determine ecosystem diversity and set coastal conservation priorities in Baja California Sur, Mexico. Specifically, coastal ecosystems that are not currently included within PNAs and which should be considered as conservation priorities were identified.
