This book was released on 2019-03-13 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.

Available in PDF, EPUB and Kindle. Book excerpt: Document from the year 2011 in the subject Agrarian Studies, University of Greenwich, language: English, abstract: It is widely recognised that environmental problems such as soil degradation (erosion and desertification) affects many agricultural lands globally. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil management practices are considered as the most vital and sustainable possible solution to control soil erosion and desertification. This management include use of organic manure, crop rotation, use of cover crop, intercropping, planting shelter belt and afforestation, provision of water ways, good surface drainage system, restoration of rangeland, regeneration and secondary forest, and political changes.

Download or read book New Strategies in Locust Control written by Stephan Krall and published by Springer Science & Business Media. This book was released on 1997-12-01 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the late eighties large-scale control operations were carried out to control a major desert locust upsurge in Africa. For the first time since the banning of organochlorine pesticides these operations relied mainly on non-persistent pesticides such as organophosphates and pyrethroids. The amount of pesticides sprayed and the area covered were probably the highest in the history of locust control and raised criticism with respect to efficacy, economic viability and environmental impact. As a consequence, applied research into the problem was intensified, both at the national and the international level, with the goal of finding new and environmentally sound approaches and solutions to locust and grasshopper control. Emphasis was laid on developing new control agents and techniques.

This book was released on 2002 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a joint project of the Southern African Development Community (SADC), the World Bank, the International Bank for Reconstruction and Development, Swedish International Development Agency (Sida) and the World Conservation Union (Regional Office for Southern Africa) which investigated the threats to precious water resources in southern Africa, and to the environment that sustains them. The full colour, glossy report was intended as a SADC contribution to the United Nations summit on Sustainable Development in Johannesburg in 2002, and to the New Partnership for Africa's Development. The report provides a framework for the sustainable management of water resources, and presents solutions for long-term protection and appropriate utilisation of water in the counties of the region ? the DRC, Angola, Tanzania, Zambia, Malawi, Zimbabwe, Mozambique, Namibia, Botswana, Swaziland, Lesotho and South Africa. Some key messages that pervade the report are: firstly that the effective and sustainable utilisation and management of water resources are essential prerequisites for sustaining all forms of life and livelihoods, and for fostering overall socio-economic development and poverty reduction in the region; and that moreover, sustainable water resources management must be balanced between the short-term needs of the people and their human development, and the protection of the natural resource base and environment.

Download or read book Conservation Song written by Wapulumuka Oliver Mulwafu and published by . This book was released on 2011 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: A CONSERVATION HISTORY WITH LESSONS FOR TODAY Conservation Song explores ways in which colonial relations shaped meanings and conflicts over environmental control and management in Malawi. By focus- ing on soil conservation, which required an integrated approach to the use and management of such natural resources as land, water and forestry, it examines the origins and effects of policies and their legacies in the post-colonial era. That interrelationship has fundamental contemporary significance and is not simply a phenomenon created in the colonial period. For instance, like other countries in the region, post-colonial Malawi has been bedevilled by increasing rates of environmental degradation due, in part, to the expansion of human and ani- mal populations, cash crop production, drought and consequent deforestation. These issues are as critical today as they were six or seven decades ago. In fact, they are part of a conservation song that has a long and complex history. The song of conservation was initially composed and performed in the colonial peri- od, modified during the immediate postcolonial period and further refashioned in the post-dictatorship period to suit the evolving political climate; but the basic lyrics remain essentially the same. This book attempts to explain the evolution of the conservationist idea whilst demonstrating changes and continuities in peasant-state relations under different political systems. The dominant narrative posits conservation as a progressive movement aimed at re-organising natural resources and protecting them from destruction but the idea was contested and deeply embedded in colonial power relations and scien- tific ethos. Conservation emerged as an important tool of colonial state interven- tion and control concerning people and scarce resources. Conservation Song shows how the idea of conservation was rooted in and driven by a particular type of science about the organisation of space and landscapes. It offers a strategic entry point to understanding the historical roots of Africa's social and ecological problems over time, which are also intertwined with power and poverty relation- ships. In the postcolonial period, the conservation tempo subsided and became neglected in public discourse, only to re-emerge in the 1990s through the democratisation movement.
