The current study shows the process and the results of a methodology proposed to contribute with the issue of how to evaluate
the adaptation to climate variability and future climate change. The proposed methodology consists of a standard to evaluate
farmer’s adaptation to climate variability, mainly due to drought in watersheds in Central America; and was created with contributions
from experts and professionals around this region. The phases for this process were: (1) literature review about the topic,
(2) development of a preliminary standard, (3) expert interviews for the evaluation of this preliminary standard, (4) construction
of a standard to evaluate the issue of adaptation to climate variability emphasizing drought through contributions from experts
and their preliminary evaluations, (5) applicability test of this standard for the evaluation of climate variability under
real conditions and (6) application of this standard through a case study in the Aguas Calientes river sub-watershed in Nicaragua,
which permanently undergoes drought problems and climate variability. This standard has five main principles that go from
the general, considering regional and national policies and institutionalism, to the specifics at the level of watersheds.
In addition to those principles, the standard contains ten criteria, 26 indicators and 51 verifiers distributed among the
main five principles. In the process for testing this standard in the Aguas Calientes river watershed in Nicaragua, the score
for the general applicability to this standard was middle-level (score of 3 in a scale of 1 to 5), although, for the main
principles of this standard, the score was four (high). 相似文献

We present four reconstruction estimates of Arkansas River baseflow and streamflow using a total of 78 tree-ring chronologies for three streamflow gages, geographically spanning the headwaters in Colorado to near the confluence of the Arkansas-Mississippi rivers. The estimates represent different seasonal windows, which are dictated by the shared limiting forcing of precipitation on seasonal tree growth and soil moisture—and subsequently on the variability of Arkansas River discharge. Flow extremes that were higher and lower than what has been observed in the instrumental era are recorded in each of the four reconstructions. Years of concurrent, cross-basin (all sites) low flow appear more frequently during the 20th and 21st Centuries compared to any period since 1600 A.D., however, no significant trend in cross-basin low flow is observed. As the most downstream major tributary of the Mississippi River, the Arkansas River directly influences flood risk in the Lower Mississippi River Valley. Estimates of extreme high flow in downstream reconstructions coincide with specific years of historic flooding documented in New Orleans, Louisiana, just upstream of the Mississippi River Delta. By deduction, Mississippi River flooding in years of low Arkansas River flow imply exceptional flooding contributions from the Upper Mississippi River catchments. 相似文献
