The Implementation and Sustainability of Village Conservation Agreements Around Kerinci Seblat National Park,Indonesia

We investigated the implementation and sustainability of village conservation agreements and village conservation grants facilitated by an integrated conservation and development project (ICDP) around the Kerinci Seblat National Park, Sumatra, Indonesia, 5 years after the project closed. Forty-three percent of agreement actions (n = 180) and 30% of grant activities (n = 74) were sustained. Informants identified numerous factors influencing success, but statistical tests failed to detect simple explanations. Conservation-livelihood agreements have a greater chance of success when preexisting factors are understood and the purpose of the agreement itself is clearly defined.     

Geographies of knowledge, practices of globalization: learning from the oil exploration and production industry

In this paper we initiate a dialogue between work on the geographies of globalization and knowledge economies, areas of inquiry that have tended to develop in isolation. We argue for a critical harnessing of these two bodies of work to (1) understand how and where different types of knowledge are acquired, produced and mobilized by firms as they seek to 'go global', (2) map the multi-scalar geographies of knowledge that enable practices of globalization and (3) examine the ways in which networks of knowledge structure emerging geographies of production. We demonstrate the potential of this move using oil exploration and production as an example.

Evaluation of Hydrologically Relevant PCM Climate Variables and Large-Scale Variability over the Continental U.S.

The ability of the Parallel Climate Model (PCM) to reproduce the mean and variability of hydrologically relevant climate variables was evaluated by comparing PCM historical climate runs with observations over temporal scales from sub-daily to annual. The domain was the continental U.S, and the model spatial resolution was T42 (about 2.8 degrees latitude by longitude). The climate variables evaluated include precipitation, surface air temperature, net surface solar radiation, soil moisture, and snow water equivalent. The results show that PCM has a winter dry bias in the Pacific Northwest and a summer wet bias in the central plains. The diurnal precipitation variation in summer is much stronger than observed, with an afternoon maximum in summer precipitation over much of the U.S. interior, in contrast with an observed nocturnal maximum in parts of the interior. PCM has a cold bias in annual mean temperature over most of the U.S., with deviations as large as ?8 K. The PCM daily temperature range is lower than observed, especiallyin the central U.S. PCM generally overestimates the net solar radiation over most of the U.S, although the diurnal cycle is simulated well in spring, summer and winter. In autumn PCM has a pronounced noontime peak in solar radiation that differs by 5–10% from observations. PCM'ssimulated soil moisture is less variable than that of a sophisticated land-surface hydrology model, especially in the interior of the country. PCM simulates the wetter conditions over the southeastern U.S. and California during warm (El Niño) events, but shifts the drier conditions in the PacificNorthwest northward and underestimates their magnitude. The temperature response to the North Pacific Oscillation is generally captured by PCM, but the amplitude of this response is overestimated by a factor of about two.     

The determination of cassiterite tin in soils and sediments by an atomic absorption-volatile hydride method

Cassiterite tin is determined after sample decomposition with ammonium iodide. The sublimate, collected in a separate condenser, is dissolved in tartaric acid solution and the tin is reduced to tin hydride in a continuous flow system by means of sodium tetrahydroborate. Atomisation is effected in a shielded hydrogen-argon diffusion flame to provide a high sensitivity determination. Interferences are negligible and the precision (12% R.S.D.) and detection limit (0.2 μ/g^-1) obtained, as well as the throughput (60 samples per hour), are suitable for geochemical exploration.
