Abstract Africa is under pressure from climate stresses and is highly vulnerable to the impacts of climate change. In Kenya, agriculture is the backbone of the economy making it an important contributor to food security of rural households. Currently crop productivity is being affected by continued climate variations and decline in soil fertility. Adaptation to climate change requires to be given high and urgent priority for sustainable crop production. A study was conducted in Mavuria ward,...
Abstract: There is evidence that food insecurity has been increasing recently in Sub-Saharan Africa. The foundation of this statement is that development of agriculture can contribute both to the increase of food supply and constitute the main source for generating income, thus ensuring access to food by the greater proportion of food insecure people. This study was guided by various objectives in reviewing the global concerns and trends underlying the threat to food security. Emphasis is on...
Abstract: Climate variability and change have serious direct and indirect consequences for crop production and nitrous oxide (N2O) emission in rainfed agriculture-based developing countries in general and in semi-arid environments like the Great Rift Valley (GRV) of Ethiopian particular. Agriculture is a sector that is vulnerable to the effects of climate change while it is contributing both as a sink and source to anthropogenic N2Oemission. Therefore, applying Climate Smart Crop Production ...
Abstract: Human-wildlife conflict (HWC) is regarded as an interaction between humans and wildlife that results in negative impacts on humans, animals, or the environment. The HWC has been a recurring problem in Ethiopia due to increased human population and competition for the declining resources. This study was conducted to assess and document the causes, impacts and management options of the effect of wild life on human in and around the study area. The study design was a longitudinal popu...
Abstract: Ethiopia’s low level of economic development with its heavy dependence on rain- fed agriculture, which is the sector most vulnerable to climate variability make the country susceptible to the adverse effects of climate change. To counter this, several measures have been suggested in attempts to reduce the vulnerability of farmers households who are the worst affected by changes in climate. One such intervention is agroforestry practices (AFP), which is probably one of the most vi...
Abstract: Climate change and variability are emerging issues across the global, especially in countries where rain-fed agriculture is a means of livelihood. Hence, the current study aimed to characterize the climate variability of the study area and its implication for potato production. Potato yield data for a period of 12 years was obtained from Agricultural Office of Kombolcha District for kiremt season. Historical rainfall and temperature data of Kombolcha station were obtained from Nati...
Abstract: Soil characterization, classification and land suitability evaluation are the main information sources for precision agriculture, land use planning and management. However, the fertility status of the soil and sustainable soil management practices that are based on the understanding of soil system are not available for most part of Ethiopia. On the basis of this fact, a study was conducted in Muger sub-watershed, North Shoa zone of Oromia region, Ethiopia to (i) characterize and cl...
Abstract: This study examines the institutional arrangement for water governance, crop production efficiency, commercialization, and impact on household welfare using cross-sectional data obtained from 544 randomly and proportionately selected sampled households from four districts of the Amhara region, northern Ethiopia. Data were analyzed using descriptive statistics and econometric models. The stochastic frontier production (cost) model was used to investigate technical (cost) efficiency,...
Abstract: The need to diversify the economy so as to ensure sustainable economic growth has been of great concern. Accelerating productivity in agriculture is seen as one of the alternatives to support the diversification initiatives by the government and drive growth in Botswana. This study discusses the factors contributing to increased long term agricultural productivity and hence its subsequent impact on growth in the short. The study employs the vector error correction model and annual ...
ABSTRACT To determine the soil's primary potentials and constraints, soil characterization and pedological classification are crucial. However, much of Ethiopia’s documented soil information is scanty and inadequate relative to the large size of the country and the wide diversity of soils and landscapes. The aim of this work was to characterize and classify the morphological, physical, and chemical attributes of soils in Aregedif watershed, Northwestern Ethiopia. Samples were collected fro...
ABSTRACT Nigerian agriculture is currently characterized by low productivity, low level of technological adoption and use of inefficient production techniques. This has resulted to reduced food production. Fishery sector in Nigeria plays an 6 important role in terms of national food security, employment, enterprise development and foreign exchange earning. Increasing efforts to raise the productivity of fishery can be an important measure to address the problem of food insecurity as well as r...
CHAPTER ONEINTRODUCTION1.1 Background of Study Nigeria is blessed with abundant natural and human resources, but despite its significant natural resources, majority of the citizens are living below the poverty line. For instance according to WDI, (2015), an estimated 60% of Nigerians live on less than US$1.25 per day. Nigeria was also ranked 91stout of a total of 104 counties on the 2015 Global Hunger Index and 153rdout of a total of 187countries on the 2012 UNDP Human Development Index. Maln...
ABSTRACT Prunus africana (Hook. f) Kalkman happens to be among the very important tree species. Its bark is used to treat prostate gland hypertrophy (PGH) and benign prostatic hyperplasia (BPH). The increased demand for its medicinal value, together with other uses, has led to the over exploitation of this species in its natural habitat. Its cultivation by small-scale farmers appears to be the only long-term solution for meeting future products needs and its conservation. There is however li...
Barley is one of the popular crops cultivated since ancient time in the world. Barley is one of the main cereal cropsproduced in the World and it is one of the most ancient crops among cereals and has played a significant role in the developmentof agriculture in the world. It is commonly used for food, animal feed and beverage value. The most important factors that reduceyield of barley is poor soil fertility, blanket recommendation of fertilizers, soil acidity (low soil pH), diseases and ins...
ABSTRACT Irrigated agriculture for Rhodes Grass and fodder production forms the backbone of many farmers in Al-Batinah and Salalah Plain of Sultanate of Oman. Ecological deterioration and inefficient water resource use have resulted in a significant threat to the livelihoods of those most dependent on agricultural sector. Inefficient water use has led to rising ground water tables and widespread water and soil salinization has resulted. The high water demand in the region for crop production...
