Salome Kimaiyo, Grace J. Cheserek and Michael N. Wabwile;JECET; September 2017- November 2017; Sec. A; Vol.6. No.4, 365-376,[DOI: 10.24214/jecet.A.6.4.36576.]

Abstract

This study examined respondents’ levels of awareness in Kenyan law and policy on forest resource management, North Rift conservancy. Forest management is faced with competing demands for various users such as government preserving economic potential of renewable resource and local communities need for wood fuel, construction material, food, fodder and land settlement. Integrating these competing imperatives requires improved understanding of how communities actually derive economic benefits from forests under community-based natural resource management as well as improved conservation of forest resources. This study attempts to review legal and policy framework for forest management in Kenya. A field study and primary data collection in North Rift conservancies were used to investigate levels of awareness on legal and regulatory framework governing forest resource management. The study established that whereas there is adequate legislation and institutional apparatus for forest resource management in Kenya, major challenges remain in the aspects of implementation of law and policy. As a result of weak and ineffective implementation of the forest resource management law and policy there is widespread encroachment on forests, depletion of forest cover and illegal logging. The study recommends urgent need for capacities building to enable existing institutions effectively fulfill their mandates.Performance gaps can be addressed through creating effective partnerships between local community forest users groups and government agencies. Such partnerships should clarify priorities and objectives for forest management law, stipulate restrictions on permitted forest use activities and entrench programs and work-plans for continuing multi-stakeholder engagement in forest resource management. There is also need to strengthen the field presence and operational capacity of forest surveillance units and the Kenya forest service enforcement teams.

Abstract

Recently, flooding is one of the major challenges facing global communities. Nigeria experienced devastating flood in 2012 that warranted federal disaster declarations. Kogi, State was among the states categorized in group (A) in national impact assessment rating (IAR) because the event brought untold suffering on the residence of the area. Flood risk communication with the general public and the population at risk is getting increasingly important for flood hazard management, especially as a precautionary measure. Flood risk mapping and analysis are vital elements in appropriate land use planning for flood prone areas. The objective of this paper is to dearcate flood risk potential areas and determines the spatial impact of 2012 flooding in kogi state. Moderate resolution imaging spectroradiometre (MODIS) data of NASA terra satellite, SRTM, land use/cover map, hydrological data and geographical information system (GIS) were used for this purpose. Five indexes of flood risk identification, namely, elevation, proximity to the river land use, population density, slope and flow accumulation were used for flood risk zonation of the study area. Each of these parameters was reclassified into four which included high risk, moderately risk, low risk, and no risk through the ranking process. The objective was to define areas with the highest risk inducing factors (most likely to flood) and assess how closely these locations are to the actual flooded areas reported during the 2012 flood. Flood risk map (FRM) was later generated by overlaying the reclassified maps of all the parameters using addition operator. This study revealed that the areas flooded in the 2012 disaster are the areas identified as high risk zones. Quantitatively, the flood risk map shows that the highly risky places covered area of 4937.055 square kilometers (17%) while moderately risky covered 6709.55 square kilometers (23%), the lowly risky areas covered 6979.02 square kilometers (24%) and no risk covers 10310.36 square kilometers (36%). This analysis further proved that 559368, 760192, 790743, and 1168164 persons are within the high, moderate, low, and no risky zones. These values corresponds to 17.06%, 23.19%, 24.12% and 35.63% of the total population of the state While a total area of 2960 square kilometers of land was inundated this constitute 10.230% of the land mass of kogi state.

Study of Low Cost Adsorbent for Drinking Water Purification

Sanwal Ram, Dr S K Pramanik, Dr Raviraj Singh, Vimla Chowdhary,JECET; June 2017- August 2017; Sec. A; Vol.6. No.3, 302-307[DOI: 10.24214/jecet.A.6.3.10116],

Abstract

This study aimed to prepare and analyze a low cost water purification system for the developing countries by the use of accessible materials. Here we have tried to study Sand Filter, Activated Carbon and Wood charcoals adsorbents for organic and metal ions, due to their availability and low cost. The current study focused on the development of an economic and efficient technology for the removal of maximum Turbidity, TDS, TSS and COD along with micro-organisms present in water samples. The water samples were physio-chemically analyzed before and after treatment according to standard procedures. The results of water sample purification by Sand Filter, Activated Carbon and Wood Charcoals were quite appreciable and showed improvement in water quality parameters. For example, it was seen in the first sample that the Turbidity reduced from 72.4 to 6.1 NTU, TSS (Total suspended solids) was reduced from 146.0ppm to 14.0ppm and COD (chemical oxygen demand) was reduced from 1016.0ppm to 172.0ppm. These results are very promising and cost effective. This study will help and benefit those who are in need of affordable technique for water purification. It could also be utilized by industries and for other domestic usage on large scale as this system does not require electricity and or any other external source to operate. This water purification system is also equipped with back washing which proves to be very important feature for low cost water purification in view of its timely cleanliness. This system is useful for house hold purpose; it can also be installed at village level, in remote and public places.

Land Use/Land Cover Change Detection Analysis in Holalkere Taluk of Chitradurga District, Karnataka, India using Geoinformatics

Abstract

Land resource is one of the highly sensitive systems that offers sustainability to all forms of life on earth. The present aim is to focus mainly on planning and management of land resources for environmental and socio-economical outcome for sustainable use to meet the future needs. Mapping of LU/LC Change Detection Analysis (CDA) was analyzed using SoI topomap; geo-rectified multi-spectral and multi-temporal image of IRS-1D PAN+LISS-III through GIS software’s. There is a significant rise in agricultural land as well as in built-up land that affecting other LU/LC categories such as mining, dumping and water crisis. Geo-informatics is one of the advent high-tech tools in analyzing the causes, rates, magnitude, patterns, trends in local scales ecosystem for better mapping and monitoring. The final results highlight the change detected on land surface features for better land utilization.
