Sustainable development of these resources to satisfy needs of the present and future generations is an absolute necessity. Achieving sustainable development is a major challenge, especially among developing fishing nations which depend more on fisheries resources. In Namibia, a developing fishing nation, many fisheries resources were over-utilized pre-independence. Thus, measures implemented post-independence were aimed at sustainable development of fisheries resources. Sustainability analysis of the Namibian marine fishing sub-sector has never been done before. Hence, this book gives a sustainability analysis of the Namibian marine fishing sub-sector using a total of seven indicators covering all aspects of sustainable development such as ecological, socio-economic, and technological. Key features of this book: Sustainability analysis of the sub-sector using indicators. Development trends construction and interpretation of the sub-sector.

The gear is used both in the inland and marine fisheries. Gillnet fishing is therefore found to be the commonest method in fishing worldwide. The use of gillnets ought to be monitored and regulated in order not to promote `growth` or `recruitment` overfishing among others. With the declining nature of fish catches which are controversial to explain in Lake Volta, fishermen deploy all sorts of illegal gillnets to increase their fishing output. This however,can have both negative and postive effects on the fishery. This work seeks to explore the changes regarding fish species, composition by number and weight, and gillnet selection parameters.

However the residues resulting from the indiscriminate use of pesticides on vegetables and fruits is a major concern in many countries including Pakistan. Moreover, the hazards to health can be minimized to a great extent if these residues are kept below their prescribed safe level (Maximum residue limit i.e. MRL). A field survey was conducted in the major growing areas of fruits and vegetables regarding the use of pesticides by local growers on their farms. In view of an indiscriminate use of pesticides, continuous monitoring for pesticide residues is needed in food crops especially fruits and vegetables in order to protect the grower s interest and consumer health. Fruit and vegetable growers should be properly educated through mass media and training workshops to create awareness about the issue of pesticide residues. ····· 10361363
für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Phosphorus (P) is an indispensable mineral for poultry, and a failure to supply satisfactory amount of this nutrient in bird s diet, leads to serious economic losses. Therefore, poultry nutritionists propose reasonable safety margin for this mineral in bird s feed. Limited resources of phosphate have been discovered and mined consistently. And ultimately, future generations will face problems in obtaining enough P to exist. Being the third most costly dietary constituent, one of the main pollutants in bird s excreta, P deserves exceptional concern in feed formulation to meet specific requirements of poultry. This book, therefore, presents basics and applications, by which, broiler feed formulators can exploit adaptation potential of modern broiler strains to cope with modest deficiency of nutrients and especially P. In addition, it would be valuable for broiler producers to lessen feed expenses, as well as, to minimize P release in surrounding environment devoid of any unfavorable effects on birds. ····· 10361352

Although total P in the soils are high but their availability to plants is too low to meet the requirements so viable strategies are needed to solublized the inorganic P and to use the RP (insoluble source of P) to decrease the dependence on costly chemical fertilizers in crop production . For the transformation of insoluble phosphorus (PR) to soluble form, composting technology would serve as breakthrough and provided optimal conditions. The objective of the study was to optimize the compost: RP ratio, time and temperature conditions for maximum solublization of P by composting. This study was undertaken to evaluate the potential of composting technology to solublize the rock phosphate in soil and also to develop optimum conditions for better release of available P for growth and development of crop plants. ····· 10361326

Via surveys, interviews and farmer group discussions, we studied the functioning of various farming systems and value chains. Findings show that in ON rice is the prime agricultural activity: though half of the farm households own cattle (for capital insurance and draught power), livestock management is troublesome due to a lack of grazing land and water points etc. Rice production is lucrative, but half of the farmers do not have the land and/or capital to attain a good production and sell a profitable price. The ON supports rice farming via the provision of infrastructure and subsidies but the hierarchical structure and limited human resources hinder the timely availability and quality of these services. More affluent farmers do cope, but poorer farmers have problems to make ends meet. Diversification towards intensive livestock production seems a possible way out. ····· 10361309

Zimbabwe performed outstandingly well with robust growth, equipped with favorable levels of biochemical and physiological characters Both gibberellic acid and brassinolide treatment enhanced plant height, number of branches, leaf number and leaf area. The rates of chlorophyll fluorescence, photosynthesis, transpiration and stomatal conductance were high under these treatments. By these favourable effects, gibberellic acid and brassinolide treatments produced more number of inflorescences and pods per plant, with better fertility coefficient. These two treatments produced higher pod and seed yields among the foliar spray treatments. Plant height, leaf number and area, chlorophyll content, soluble protein content, nitrate reductase activity, stomatal conductance and transpiration, number of inflorescences, pod yield and number of pods per plant are dominant traits which influence final seed yield in jatropha. ····· 10361276

Descriptive statistics show that chips, chicken, sausages, meat and `chaps` are the most consumed fast-foods. Consumption of these foods are motivated by their tasty and convenient nature. Results from the Heckman model show that age, household size, education level and distance from work-place to restaurant negatively influenced the probability and level of fast-food consummption while disposable monthly income and time spent away from home had positive effects on the probability and expenditure level of fast-foods. Developing countries like Uganda are increasingly adopting the lifestyle of developed countries and this has led to a high demand for fast-foods by the middle class in urban centres like Kampala.

The search for viable alternatives to conventional methods of food appropriation is becoming ever-more urgent. This dissertation examines the factors involved in the current UK food system and the relationships between these factors. The dynamics of these relationships are assessed as are their contributions to the current problems which exist both within the UK and externally. It is proposed that food systems and the relationships which underline them are highly influential upon the character and development of society and should therefore have a key role in the strive for environmental sustainability. This essay offers recommendations of potential methods which could be employed not only to decrease the negative environmental impacts of the British food system, but to enhance community relations, standards of living and social equity. ····· 10361193

But how do farmers perceive the consequences of deforestation and the disintegration of the watershed functions in their area Through in-depth interviews and questionnaires, systematised knowledge base of farmer knowledge on water and soil functions has been constructed. The collected knowledge has been compared to both scientific knowledge and knowledge of other stakeholders in the area. The findings of the research are that local farmers display a profound and detailed understanding of soil and water functions. Their local ecological knowledge is found consistent with and comparable to scientific hypotheses. However, farmers clearly lack the incentives to implement their rich knowledge in practice.

The food, fodder and fuel production in developing countries will have to be increased by 60% in the next 25 years to meet the needs of growing population. Thus, efforts be made to increase productivity of agricultural land by advocating agroforestry as one of the most practical way of meeting the needs. Agroforestry systems are often claimed to be superior to agricultural systems because of their ability to contribute to sustained production of crops and also play a promising role for environmental consideration. Fruit tree based agroforestry involves intentional and simultaneous association of annual or perennial crops with perennial fruit-producing trees on the same land unit. The relatively short juvenile (pre-production) phase of fruit trees, high market value of products and the contribution of fruits to household dietary needs, fruit-tree-based agroforestry enjoys high popularity among producers worldwide. ····· 10361159

The delicate balance between these two groups is disrupted largely due to injudicious use of insecticides Presently the management of these pests relies solely on the use of synthetic insecticides. But injudicious use of these insecticides has resulted in the development of resistance problem and environment pollution therefore, because of unique properties of specifically, safety and biodegradation microbial insecticides are an attractive alternative to chemical insecticides in insect pest management system. Moreover, the development of resistance to chemical insecticides and concern over the deleterious effects of chemicals on environmental and human safety have provided a strong impetus for the development of microbial control agents for use in integrated controls of these insect pests. ····· 1036180· 1 · ::::: · 83 ·· 84 ·· 85 ·· 86 ·· 87 ·· 88 ·· 89 · ::::: · 90 ·
