Master's Thesis from the year 2007 in the subject Agrarian Studies, grade: Merit class, Natural Resources Institute - University of Greenwich at Medway (-), course: Plant Health and Protection, language: English, abstract: Although it is widely recognised that environmental problems such as soil degradation erosion and desertification threaten sustained agricultural production in many States of northern Nigeria including Adamawa, Bauchi, Borno, Gombe, Jigawa, Kaduna Kano, Katsina, Kebbi, Sokoto and Zamfara. Very little information is available about the current status of the potential impact of soil degradation and whether the situation is worsening in all the States of northern Nigeria. However, it is now clear that the major factor explaining the severity and spatial distribution of soil degradation such as erosion and desertification in northern Nigeria is associated with human impact such as deforestation and mismanagement of land resources. Other factors includes overgrazing, use of mechanized equipment, deforestation and lack of government concern to protect the environment in the region, but few studies have been made on applied issues related to the physical and chemical processes including erosion, runoff and leaching. These problems are widely considered as a serious problem to agricultural production and its environmental consequences will remain an important issue during the 21st century. Possible solutions such as soil management practices will help to minimise/control soil degradations which caused serious hazards to farmer's land in northern Nigeria. Sustainable soil management practices are vital for enhancing and sustaining the productivity of soil, food, livestock, water quality and other related land resources such as forestry in northern Nigeria. It is more efficient in terms of reduced environmental impact, high risk of soil degradation and soil erosion. These management practices are: (a) applying organic manure regularly, (b) growing cover c

This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.

This study examines the current and potential role of economics in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the contribution of conventional economic analyses, it considers more innovative approaches that enable economics to play a greater role in the planning and evaluation of soil productivity, enhancing measures at farm, national and global level. In the past economics has tended to focus on one factor at a time but many factors affect soil productivity. Decisions, policies and their impact call for a more integrative, participatory analytical approaches capable of weighing various aspects simultaneously. This study highlights how economics can respond to this challenge through the a[application of fresh concepts (e.g. natural capital) and specific techniques (e.g. multi-criteria analysis, green accounting).

Research Paper (undergraduate) from the year 2013 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: B, University of Greenwich, language: English, abstract: It is believe that a better understanding of agricultural soil environment is a key to better soil quality and high crop yield. Understanding the soil problems would certainly leads to solutions on how to tackle them. However, this could not only serve as a part of soil management but also as a part of economic development. For instance, when mother is healthy and fertile, there is more expectation from her to provide healthy and quality produce but when there is deficiency in any of the elements (either macros or micros elements), her produce may also affected, hence increasing poverty and hunger. High quality and fertile soil always provide better condition for the growth and development of plants (right from seed germination up to the maturity stage). Example, deficiency in N, P, and K in soil might lead to several problems to growing plant in a particular soil environment. These problems may include poor germination, stunting, and defoliations of plants, late maturity and also susceptible to both pest and disease attack leading to poor yield of the crops. Therefore, understanding soil environment is a key to high yield of crop production in the north-west one of northern Nigeria.

This book constitutes the refereed post-conference proceedings of the 4th EAI International Conference on Innovations and Interdisciplinary Solutions for Underserved Areas, InterSol 2020, held in Nairobi, Kenya, in March 2020. Due to the COVID-19 pandemic the conference is postponed to a later date in 2020. The 20 papers presented were selected from 50 submissions and issue different problems in underserved and unserved areas. They face problems in almost all sectors such as energy, water, communication, climate, food, education, transportation, social development, and economic growth.

This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and in which there is a great deal of public controversy. The book includes case studies of African, Asian, and Latin American countries that demonstrate the varied effects of population growth on land use. Several general chapters address the following timely questions: What is meant by land use change? Why are ecological research and population studies so different? What are the implications for sustainable growth in agricultural production? Although much work remains to be done in quantifying the causal connections between demographic and land use changes, this book provides important insights into those connections, and it should stimulate more work in this area.
