Current State of Energy Production in Cameroon and Projection for 2035

The low electricity supply rate is a major cause of underdevelopment in Cameroon. To address this issue, Cameroon outlined a strategy in 2003 aiming for a production capacity of 3000 MW by 2020. However, by 2020, production had only reached 1040 MW, leading Cameroon to devise a new national energy sector development strategy targeting 5000 MW by 2035. This paper provides an overview of the current state of energy production and projects future output by 2035. Scientific articles and investigative reports on energy production in Cameroon have enabled an assessment of the current electrical energy production. The 2035 production estimate is based on the Energy Sector Development Projects (PDSEN) report in Cameroon. The current production is estimated at around 1600 MW. Considering the ongoing construction of power plants, future projects, and financing delays, achieving the 5000 MW goal by 2035 appears challenging. Nonetheless, diversifying energy production sources could bring Cameroon closer to this target.

Small Ruminant Production and Marketing Practices in Harawa, Somali Region, Ethiopia

Small ruminant production is an essential component of agricultural activity for smallholder farmers. The aim of this study was to assess small ruminant production and marketing practices in the Harawa district of Somali Region, Ethiopia. For the study 90 households owning small ruminant were selected from three different towns of Harawa district. Information on sheep and goat ownership patterns, production objectives, and management and production constraints were collected from 90 households using semi structured questionnaires. The available feed resources are grass species, crop aftermath and legumes species are the common ones. The average family size was 5.78 ± 0.235 persons per household. Crop-livestock farming was the commonly used farming system with (62.75%) extensive and (27.25%) semi-intensive production system. The mean total land holding was 6.08 ± 0.24 ha per HH and was significantly (P < 0.05) varied across production systems. On average, the sample households owned 46.32 ± 1.22 sheep, 38.28 ± 1.40 goat, 4.85 ± 0.43 cattle, 4.15 ± 0.54 camel, 2.18 ± 0.19 donkey and 0.53 ± 0.20 poultry. The finding shows most of the respondents kept sheep and goats for insurance as ranked first. Feed shortage was ranked first as the main constraint hindering sheep and shortage of veterinary service, drought, disease, water shortage and poor infrastructure were the other major constraints of sheep and goat production in the study area. The major production and marketing constraints in small ruminant production in the area are disease and parasite (cadho), feed and grazing land shortage, low productivity, poor veterinary service and poor of infrastructure. Therefore, it is important to use modern production systems with improved technology in the area and improve traditional system through feed supplementation and better health care. As well as improving marketing efficiency through appropriate policy and provision of information is important.

Application of Deep Learning to Production Forecasting in Intelligent Agricultural Product Supply Chain

Production prediction is an important factor influencing the realization of an intelligent agricultural supply chain.In an Internet of Things(IoT)environment,accurate yield prediction is one of the prerequisites for achieving an efficient response in an intelligent agricultural supply chain.As an example,this study applied a conventional prediction method and deep learning prediction model to predict the yield of a characteristic regional fruit(the Shatian pomelo)in a comparative study.The root means square error(RMSE)values of regression analysis,exponential smoothing,grey prediction,grey neural network,support vector regression(SVR),and long short-term memory(LSTM)neural network methods were 53.715,6.707,18.440,1.580,and 1.436,respectively.Among these,the mean square error(MSE)values of the grey neural network,SVR,and LSTM neural network methods were 2.4979,31.652,and 2.0618,respectively;and theirRvalues were 0.99905,0.94,and 0.94501,respectively.The results demonstrated that the RMSE of the deep learning model is generally lower than that of a traditional prediction model,and the prediction results are more accurate.The prediction performance of the grey neural network was shown to be superior to that of SVR,and LSTM neural network,based on the comparison of parameters.

Optimal production lot sizing model in a supply chain with periodically fixed demand considering learning effect

This paper presents an optimal production model for manufacturer in a supply chain with a fixed demand at a fixed interval with respect to the learning effect on production capacity. An algorithm is employed to find the optimal delay time for production and production time sequentially. It is found that the optimal delay time for production and the production time are not static, but dynamic and variant with time. It is important for a manufacturer to schedule the production so as to prevent facilities and workers from idling.

Cassava sector development in Cameroon: Production and marketing factors affecting price

Regular and available supply is the prerequisite of an effective and efficient commercialization process. Using multivariate regression analysis on field data, this research appraises the production and marketing factors that influence cassava market price. The production factors include cultivated area, planting material, yield, and farmers’ field schools;while farmers access to a paved road, having a telephone, the transportation costs of fresh roots, the level of root perishability, and the prices of rice and maize stand as marketing factors. The results show that farmers who attended farmers’ field school adopted improved planting materials, propagated them in their localities and the yields in these communities increased significantly. The farm size also has a significant influence on the availability of fresh roots. On the marketing side, transportation costs, access to a paved road, the prices of rice and maize significantly affect cassava’s market price and tighten the relationship between producers and marketers. We conclude that to increase fresh roots supply, roads leading to cultivating areas should be paved, better transportation provided, communication costs reduced, even distribution of planting materials and appropriate warehouses.

By the end of November 2016,most of mature citrus products in Chongqing would show different degree of rise in purchasing price,while the purchasing price of red orange and some processed raw material fruits would show different amplitude of decline. On the whole,the production and marketing situation of Chongqing citrus would become better.

Impact of Khat Production and Marketing on the Livelihood of Smallholder Households in Ethiopia

Khat, Ethiopia’s largest export cash crop, is the backbone of the Ethiopian economy. However, Ethiopia has not yet fully promoted its position as the utmost producer and exporter of khat in a global market because of its different policy discourses and illegal trade issues on khat production. The life of many smallholder households relies on khat production and its marketing in a country. Hence for thus, some information has been gathered on different aspects of khat with the objectives of reviewing khat’s impacts on the livelihood of smallholder farmers, its production status, and marketing constraints in Ethiopia. To review these objectives, data from CSA, and different published materials on khat were used. According to the review, khat production has a positive impact on securing household food insecurity and improving the livelihood status of smallholder farmers, and the largest foreign exchange-earning cash crops. However, it is exploited almost in all parts of a country’s government policy discourse on khat production and its trade legal issues, lack of infrastructure, zero access to extension services, zero tangible value addition, inadequate technology transfer, and research, and price volatility because of product perishability behavior are among major constraints threatened in khat production in Ethiopia. Its vulnerable and corrupted marketing system, zero market promotion and political dichotomy, long market chain, chronic market information, and unfair price were reported by different scholars as major problems of khat marketing in Ethiopia. From these probs: The government should analyze why and its impact on khat production discourse policy on the livelihood of smallholder households and overlook positive policy proclamation. Encouraging research and technology transfer to transform products into manufacturing industries, enhancing infrastructural and institutional facilities, and improving khat production product technologies through development, and khat production agribusiness industry transformation, institutionalizing its marketing arrangement and other related agronomic practices are among the major recommendations to forward so.

On Structure,production,and market of bamboo-based panels in China

Since bamboo has the advantages of straight grain, beautiful color, high strength and toughness, and excellent abrasion resistance, bamboo-based panels have been widely used in the fields of vehicle, construction, ship building, furniture, and decoration to partly take the place of wood, steel, plastic etc in China. This paper briefly described the basic component units, including strip, sliver, and particle, of bamboo-based panel and pointed out that to design the structure of bamboo-based panels should follow the principle of symmetric structure, surface forming method, and structuring principle of equalizing stress.

Analysis and Thinking on Citrus Production and Marketing Situation of Hunan Province in 2017

In 2017,both the planting area and yield of the citrus in Hunan Province increased,but some production areas suffered decline in yield due to abnormal climate. The sales price of citrus in the whole province increased compared with the previous year,and the sales progress was faster than the previous year. Due to the much increase of planting costs,the income of citrus growers declined. Therefore,it is recommended to promote the development of citrus industry in Hunan Province through strengthening the overall planning of the industry,consolidating the seed base,developing primary processing and deep processing,and enhancing brand building.

Impacts of Climate Change on Water and Agricultural Production in Ten Large River Basins in China

The overall goal of this paper is to examine impacts of climate change on water supply and demand balance and their consequences on agricultural production in ten river basins in China. To realize this goal, China Water Simulation Model （CWSM） is used to analyze three alternative climate scenarios （A1B, A2 and B2）. The results show that the impacts of climate change on water supply and demand balance differ largely among alternative scenarios. While significant impacts of climate change on water balance will occur under the A1B scenario, the impacts of climate change under the A2 and B2 scenarios will be marginal. Under the A1B scenario, the water shortage in the river basins located in the northern China will become more serious, particularly in Liaohe and Haihe river basins, but the other river basins in the southern China will improve their water balance situations. Despite larger impacts of climate change on water balance in the northern China, its impacts on total crops＇ production will be moderate if farmers would be able to reallocate water among crops and adjust irrigated and rainfed land. The paper concludes with some policy implications.

Direct farm, production base, traceability and food safety in China

With the rapid growth of China＇s economy, rising demand for safety food has been accompanied by frequent food safety scandals. Given that China＇s farming is dominated by millions of small-scale farms, ensuring food safety is a major challenge facing the public and private sectors. The direct farm （DF） program, initiated in 2008, represents one of the government＇s major initiatives to modernize the distribution of fresh fruit and vegetables （FFV） and improve food safety. Under the DF program, participating national and international retailers are expected to establish more direct procurement relationships with farm communities. While it is often claimed that greater participation by retailers in the production and post-harvest processing implied the DF program will lead to improved quality, safety and traceability, systematic evidence remains elu- sive as existing studies are largely narrative, based on case studies, or theoretical inference. Little empirical evidence is available for a broader evaluation of the DF program. This paper aims to fill this gap by assessing the overall performance of a single retailer＇s DF experience with respect to the procurement and food safety of FFV. We use data from a survey of production managers of 35 DF production bases （PBs） spread across 11 provinces, 3 cities and 1 autonomous region in China. The results show a mixture of opportunities and challenges. On one hand, the DF program improves production practices and distribution channels of FFV produced on its PBs, thus facilitating the move of China＇s food system towards improved food safety compliance. On the other hand, significant heterogeneity in the traceability of food and the ability of DF to meet higher safety standards is evident both across major product categories and across household-operated vs. firm-operated PBs. The paper concludes with policy implications.

A Markov-switching dynamic regression analysis of the asymmetries related to the determinants of US crude oil production between 1982 and 2019

The structural changes brought about by shale oil revolution have inspired this paper of which the aim is to analyze the potential asymmetries related to the determinants of crude oil production in the USA.Thus,using a Markov-switching dynamic regression model in which parameters change when oil production moves from one regime to the other,it is found that for both oil production and oil relative importance,the regime that was dominant during the 1980s and the early 1990s when oil production in the USA was substantially high is the same regime that has once again become dominant in the decade corresponding to the shale oil revolution.Furthermore,the study reveals the existence of asymmetries in the relationship between US crude oil production and both manufacturing production and the consumer price index.Asymmetries are also found in the relationship between the relative importance US crude oil and manufacturing production.Finally,it is found that the intercept and the variance parameter also vary from one regime to the other,thus justifying the use of regime-dependent models.

Agricultural production structure,market conditions and farmers’nutritional intake in rural China

Nutrition poverty alleviation is an effective measure to improve the nutritional status of economically disadvantaged individuals,fundamentally improving their health and reducing poverty.Based on the Entitlement Theory and using the China Health and Nutrition Survey(CHNS)data,this paper examines the relationship between farmers’nutritional intake,production structure and regional market conditions.Results show that farmers with diversified production have better nutritional intake than those who specialize.Furthermore,the correlation between regional market conditions and nutritional intake varies between economically disadvantaged and non-economically disadvantaged households.Market conditions significantly influence the carbohydrate and fat intake of economically disadvantaged households and are positively associated with the dietary structure and nutritional intake of non-economically disadvantaged ones.Moreover,income is positively correlated with the nutritional intake of non-economically disadvantaged households but not with economically disadvantaged ones.

Begait Goat Production Systems and Breeding Practices in Western Tigray, North Ethiopia

A study was undertaken to characterize production system, breeding practices and production constraints of Begait goat in Kafta humera district, northwestern lowlands of Ethiopia. Personal observations, focus group discussions and a detailed structured questionnaire were used to collect data from 150 respondents (99 small-scale and 51 large-scale farmers). Mixed crop-livestock production system was found to be the dominant farming system in the study district. The farmers kept a variety of livestock species including goats, sheep, cattle, chickens and donkeys. Small ruminants are the most numerous and are of great importance in the area. Goats are herded with sheep in the open fields by the young boys in the family/hired grazers. They have a number of roles though mainly kept as a source of cash income. Breeding was generally uncontrolled. Size, growth rate and libido were the most frequently reported traits in selecting bucks, whereas does were selected based on size, twining ability and milk yield. Effective population size and rate of inbreeding were calculated by considering random mating and flocks were not mixed. The major constraints hampering goat production in the area were water scarcity, feed and grazing land shortages and insufficient veterinary services among the others. Therefore, addressing these constraints is important to design a successful genetic improvement scheme in the area for goat.

Collaborative production planning between supply chain partners by Lagrangian relaxation

A collaborative planning framework based on the Lagrangian Relaxation was developed to coordinate and optimize the production planning of independent partners in multiple tier supply chains. Linking constraints and dependent demand constraints were added to the monolithic Multi-Level, multi-item Capacitated Lot Sizing Problem (MLCLSP). MLCLSP was Lagrangian relaxed and decomposed into facility-separable subproblems. Surrogate gradient algorithm was used to update Lagrangian multipliers, which coordinate decentralized decisions of the facilities. Production planning of independent partners could be appropriately coordinated and optimized by this framework without intruding their decisionities and private information. Experimental results show that the proposed coordination mechanism and procedure come close to optimal results as obtained by central coordination.
