In this paper we consider the different locations of Zhejiang (ZJ) provincial area including Hangzhou Bay (HZB), Ningbo (NB), Zhoushan (ZS), Taizhou (TZ) and Wenzhou (WZ) subareas to find out 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...

We conducted a detailed study in comparing physico-chemical parameters of glacier melt water between two years (2016 & 2019) in upstream sites with an elevation ranging from 4100 m to 3550 m above sea level of Ponkar glacier, Manang district, Nepal. We conducted onsite testing of physical parameter like pH, electrical conductivity, total dissolved solids, turbidity by using multiprobes and chemical parameters like anions, cations, total silica and heavy metals were analyzed following standard me...

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...

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...

This study presents a comparison between two bathymetric datasets covering the continental shelf of Cameroon. One of these datasets, Campus Cameroun, is based on a specific single-beam echosounder survey used in an authoritative study. The other is an excerpt of the SRTM15 V2.0,—free and open Global Bathymetry and Elevation Data model which provides background information for Google Earth, G ...

This paper analyses the differences between policies in Chinese and American national parks, including the role of communities, the permitting and reservation system, and camping. It also describes additional recom-mendations related to developing community-based tourism, the e-commerce market, and data statistics tools. What is the best way to support communities economically at the boundaries of national parks? The American expe ...

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 need for perception studies to drought is informed by the fact that different people perceive drought differently and derive local adaptation measures based on their individual perception. The objective of the study was to establish the household perceptions to drought and the factors that influence formation of such perceptions in Laikipia West sub-County, Kenya. The study adopted a household survey research design. The study ...

Severe drought has affected Kenya in the past
decades reducing crop yields leaving millions of people in dire need of food.
Drought cycle in Kenya has reduced increasing drought frequency in the recent
decades. This study assessed drought characteristics in Laikipia West
sub-County which lies in a region classified as arid and semi arid. The
specific objective of the study was to analyze
seasonal and annual drought characteristics ...
