In this paper we consider the Zhejiang (ZJ) provincial coastal area to find the sea level (SL) variations. Sea Surface Height Relative to Geoid over these areas has been obtained from the satellite altimetry data produced routinely by the European Centre for Medium-Range Weather Forecasting (ECMWF) and Archiving, Validation and Interpretation of Satellite Oceanographic (AVISO) data. Monthly, seasonal and interannual variations of SL over ZJ have been presented ...

Philippines has about 7100 islands with 3 major islands, Luzon, Visayas, and Mindanao and has about 18,000 km of shorelines with vast areas of mangrove ecosystem. Government policies, which dictated development in both the uplands and coastal areas, have been based mainly on abundant available resources without due consideration for sustainability. The study was conducted for the purpose to identify mangroves diversity and assessment in selected area along Butuan Bay, Agusan del Norte, particula...

Soil erosion is an
important cause of land degradation and consequent to soil fertility which
reduces land productivity and production. This problem aggravates in developing
countries like Ethiopia. To minimize this challenge, soil and water
conservation with proper design is the first choice. The aim of this study was
to assess the adoption and effect of Vetiver grass on soil erosion in Somodo
watershed. Community mobiliz ...

The use of seasonal
climate forecasts can inform implementation of planned adaptation strategies to
stabilize pastoral livestock assets in drought prone agro ecological zones. The
main objective of this study was to assess use of seasonal climate forecasts as
strategies for securing pastoralists assets in arid and semi-arid lands (ASALs)
of Baringo County. The study used five (5) study locations that were
purposively picked to ens ...

The study was undertaken
to determine rainfall variability and droughts in arid and semi-arid lands
(ASALs) of Baringo County. The study used rainfall data for Perkerra Agricultural
Research Station (LM5) and Nginyang rainfall station (IL6) for the period
1970-2008 and 1974-2013 respectively. Standardized anomalies were calculated
and plotted to establish trends of drought events across the study period.
Plots of rainfa ...
