Soil Erosion Risk Assessment Using GIS Based USLE Model for Soil and Water Co...Agriculture Journal IJOEAR
— Soil erosion is natural phenomena and is modified by biophysical environment comprising soil, climate, terrain, ground cover and their interactions. Due to different factors, it is difficult to make watershed management successful in all areas at one time. Because of this, prioritization of sub watershed is very important for soil conservation planning and implementation. In Somodo watershed more than five years different soil and water conservation technologies were implemented and satisfactory result was not recorded. In this aspect, it is important to consider further watershed management planning., This study therefore investigated soil erosion risk assessment using GIS and USLE model for soil and water conservation in Somodo watershed southwestern Ethiopia with the aim of estimating soil erosion rate and identify soil erosion hot pot areas through prioritization of sub watershed in Somodo watershed by the help of GIS based USLE model. Both primary and secondary data sources were used for model input. These data were computed at a grid level with 30*30m resolution and then overlaid to generate mean annual soil loss by the help of raster calculator in Arc GIS tool. Results of the study showed that, the mean annual soil loss of the watershed was 18.69 ton ha-1 year-1 ranging from 0 to 131.21. More than 75% of the watershed have soil loss greater than 20 ton ha-1 year-1 and only 25% of the area have soil loss less than 10 ton ha-1 year-1 .On the bases of mean annual soil loss SW-4, SW-6 and SW-7 were under slight (0-10 ton ha-1 year-1) erosion severity level, while the remaining SW-2, SW-3 and SW-8 were under moderate (10-20 ton ha-1 year-1) level. And SW-1 was in high (20-30 ton ha-1 year-1) erosion severity level, where as SW-5 and SW-9 were found in very high (>30 ton ha-1 year-1) erosion severity level. Since large area of the watershed has soil loss more than tolerable level (11 ton ha-1 year-1) attention should be given to identify erosion hot spot areas to minimize the on-site and off-site problems. Therefore, the study suggested that for effective watershed management and soil conservation planning, these sub-watershed priorities should be used in the watershed.

Effect of Rainfall Trend on Yam Yield in Mokwa Local Government Area of Niger...CrimsonpublishersEAES
Agricultural production in Niger State like other states in Nigeria is highly vulnerable to climate changeability. Climate change is predicted to have adverse effects on the agricultural sector of the poorer parts of the world especially sub-Saharan Africa. The aim of the study is to investigate and analyse the effect of rainfall trend on the production of yam in Mokwa local government area of Niger state, Nigeria. For the purpose of this research, data were collected from 100 respondents through the administration of questionnaires. Rainfall data covering a period of thirteen years (2003-2015) were also obtained from College of Agriculture Mokwa weather station, while the yearly yam yield for 16 years (2000-2015) was obtained from Niger State Ministry of Agriculture.
Linear regression models and standardized anomaly index were used to analysis the data gathered. The study showed that the trend of mean annual rainfall in the study area was minimal but significant with R2 value of 0.8 for mean monthly rainfall. A strong relationship between rainfall variation and yam yield exist with r2 value of 0.881. The variation in the yield among the years was moderately significant with R2 value of 0.5064. It also showed a positive response between yam yield and moderate rainfall that was well distributed. Extension agent from ministries of agriculture and ADPs should do more in harnessing relevant information on food production in all the local government areas of Niger state so as to build a robust data bank for further research.

Review on the Cause and Effects of Recurrent Drought on Ethiopian Agriculture...AI Publications
Drought occurs in virtually all climatic zones, but its characteristics vary significantly from one region to another. Ethiopia characteristically sees three seasons of varying amounts of rainfall. The central western regions getting a sufficient amount of rain during the rainy season, but the rest of the country, especially towards the horn being very dry for most time of the year. This also leads that some parts of regions of Ethiopia severely affected by recurrent drought. Recurrent drought caused by deforestation, high population growth, land degradation and soil erosion which intern affect agriculture include crop losses, lower yields in both crop and livestock production, increased livestock deaths and generally it may bring economic, environmental, and social impacts. Different efforts are made by policy maker and government to reduce or mitigate the impact of drought but still the impact is there thus this review show the gap.
THE OPPORTUNITIES AND CHALLENGES FOR MITIGATING CLIMATE CHANGE THROUGH DROUGH...Julius Huho
The economy of Kenya is based on agriculture which in turn depends on rainfall performance. Over 80 percent of the Kenyan population relies on rain-fed agriculture as a livelihood source. Unfortunately, changes in its amount, timing and distribution in the last two decades have influenced the reliability of rainfall for agricultural purposes. The consequence has been recurrent food insecurity in most parts of the country and chronic in the arid and semi arid areas due to frequent droughts. To survive the harsh climatic conditions, the affected communities employ various adaptive strategies. The current study examined the drought adaptive strategies employed by subsistence farmers in the semi arid areas of Kenya in relation to mitigating climate change. Data was obtained from Mukogodo and Central Divisions of Laikipia County, Kenya. Time series was used to analyze rainfall trends. Data on effects of droughts and adaptive strategies was obtained through in-depth interviews. The inhabitants were aware of climate change with 90% and 10% of the respondents attributing the changes to human activities and divine forces, respectively. Rainfall showed a declining trend in Mukogodo Division but an increasing trend in Central Division. Nevertheless, the timing of the "long rains" and the length of the growing season in Central Division showed considerable changes. The consequences were food insecurity and livelihood destruction in the area. The adaptive strategies employed aimed at cushioning farmers against immediate problems but with minimal consideration of climate change mitigation. This paper highlights on the opportunities and challenges of mitigating climate change that farmers had through their day-to-day adaptive strategies.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. In Egypt, drought is closely linked with land
degradation (desertification) yet meteorological drought
is usually considered. This drought is defined as the
degree of dryness specified by difference of precipitation
and the duration of the dry spell which is distinguished
into absolute and partial drought. Absolute drought is
said to be 15 consecutive days none of which is credited
with 0.2 mm or of rainfall whereas partial drought is a
period of at least 29 consecutive days of which is main
rainfall does most exceed 0.2 mm.
4. In Egypt, Many areas receive no rainfall for months
or even years due to the extremely random storm
patterns (about 75% of the whole territory). During the
winter months (November – February), Egypt is
influenced by the Mediterranean depression and Sudan
low trough, while in the spring (March - May) the
southern and western winds become more effective.
The coefficient of drought variation in the
Mediterranean region which is the ratio of the net
radiation left on the surface to the product of the annual
rainfall at the evaporation temperature attains its highest
value in the desert areas where it usually exceeds 3,
while it is of the order of 1.5 in Europe (Accad – Unesco
1988).
5. As reported in the NAP report (2005), Egypt is classified,
on environmental basis, into four agro- ecological zones;
namely:-
- North Coastal Zone
- Nile Valley and Delta
- Inland Sinai and Eastern Desert
- Western Desert
The areal distribution, as well as the population
density over such zones are given in Tables (1&2) and
Map (1).
Climatically, the territory of Egypt is dominated by
arid to hyper arid conditions. Table (3) and Maps (2&3)
show the distribution of rainfall and aridity among the
assigned four agro-ecological zones.

11. Strategies for Avoiding Water Scarcity and Drought.
The Government of Egypt (MWRI) has formulated
strategies to face water scarcity and drought to the
years 2017 and 2050.
• Well- defined laws and regulations for controlling
groundwater consumption are necessary to avoid
further depletion and / or pollution.
• The use of water saving devices on each well is quite
important, in the developed aquifers in general and in
the coastal aquifer in particular.
• Regional, sub-regional and local technical agencies
responsible for water services are badly needed to
ensure policy cohesion and public support.
• The use of different techniques for runoff water as well
as rain water harvesting in the rainy seasons.
12. • Ensuring women’s participation in local decision
making bodies particularly in the frame allocation and
water saving purposes.
• Periodical monitoring of groundwater level and salinity
through a suitable network of the exhausted aquifers.
• Training of locals for groundwater works and usage.
• Provide the necessary information for monitoring the
effects of desertification and produce exhaustive
inventories of land degradation.
• Use of brakish water for sand dune fixation, and for salt
resistant plantation.
•
