This study investigates the efficacy of erosion control structures (ECSs) as restoration tools in the context of a watershed rehabilitation and wet meadow (bofedal) restoration program in the Bolivian Andes. In an effort to enhance water security and increase grazing stability, Aymara indigenous communities built over 15,000 check dams, 9,100 terraces, 5,300 infiltration ditches, and 35 pasture improvement trials. Communities built ECSs at different rates, and we compared vegetation change in the highest restoration management intensity, lowest restoration management intensity, and nonproject control communities. We used line transects to measure changes in vegetation cover and standing water in gullies with check dams and without check dams, and related these ground measurements to a time series (1986-2009) of normalized difference vegetation index derived from Landsat TM5 images. Evidence suggests that check dams increase bofedal vegetation and standing water at a local scale, and lead to increased greenness at a basin scale when combined with other ECSs. Watershed rehabilitation enhances ecosystem services significant to local communities (grazing stability, water security), which creates important synergies when conducting land restoration in rural development settings.}, language = {en} } @article{Klose2015, author = {Klose, Claudius}, title = {Sentence Type and Association with Focus in Aymara}, series = {Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632}, journal = {Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632}, number = {19}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1614-4708}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-83768}, pages = {63 -- 86}, year = {2015}, abstract = {Sentence type marking is realized by two suffixes in Aymara, one marks declaratives and the other polar sentences (polar questions and negated sentences) by picking out one or two propositions, respectively.

The sentence-type-related suffixes associate with focus and the additive can associate with focus by attaching to the focused constituent.}, language = {en} }
