Assessment of Livelihood Vulnerability to Rainfall Variability among Crop Farming Households in Kitui South Sub-County, Kenya

Morris M. Mwatu, Charles W. Recha, Kennedy N. Ondimu
Rainfall variability has negatively impacted rain-fed crop farming in arid and semi-arid lands increasing households’ vulnerability. This study sought to establish the extent to which rain-fed crop farming households in Kitui South sub-County in semi-arid Southeastern Kenya are vulnerable to rainfall variability. The study used index-based approach where Livelihood Vulnerability Index (LVI) for each of the randomly sampled 311 households was calculated using the IPCC framework. Rainfall data for...

Sea Level Variations of Zhejiang Province, China

Pingbo Wang, Liuzhu Wang, Mantravadi Venkata Subrahmanyam
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

Species Composition, Diversity and Habitat Assessment of Mangroves in the Selected Area along Butuan Bay, Agusan Del Norte, Philippines

Alvin B. Goloran, Calagui Laurence, Betco Glenn, Mulgado April Tricia
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...

Enabling Conditions for Improved Use of Seasonal Climate Forecast in Arid and Semi-Arid Baringo County—Kenya

Richard Ochieng, Charles Recha, Bockline Omedo Bebe
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
