Book Description
Most African countries strive for both poverty reduction and sustainable land management, yet information on the exact relationship between these goals is limited. This report seeks to fill the gap by demonstrating a strong linkage between poverty and land management. Using Uganda as a case study, the authors show that certain policies, such as investments in soil and water conservation and agroforestry, may simultaneously increase productivity and reduce poverty and land degradation. Other strategies, including development of rural roads, non-farm activities, and rural finance, may reduce poverty without significantly affecting productivity or land management. Some policies, however, will likely involve trade-offs among different goals and will need to have their negative impacts minimized. Those in government, NGOs, the private sector, or academia who are concerned about sustainably reducing poverty in Sub-Saharan Africa will benefit from this analysis of how to pursue these key development goals.

Book Description
Remediation and Management of Degraded Lands presents the program of the first International Conference on the Remediation and Management of Degraded Lands. This collection reviews the extent of resource debasement and offers solutions for their restoration. The 14-part first section deals with mine management and rehabilitation. Topics include the devastating results of open-cut mining, open-pit mining, lignite surface mining and acid mining. Despite such ruin, the articles reveal the possibilities for reclamation. Part two devotes nine chapters to the management of derelict lands. Reforestation, soil fertility prognosis, and the uses of nitrogen are just a few of the covered subjects. This portion of the book pays special attention to the successful results of remediation in China and Hong Kong. The final division addresses soil contamination and reclamation. There are eleven chapters on subjects that include the single and interactive effects of aluminum, the effectiveness of EDTA/HCI and the value of pig-on-litter compost as a tool for edible crop growth. These and other innovative techniques make Remediation and Management of Degraded Lands a valuable addition to any environmental library.

Book Description
It is increasingly recognized that land can be managed most sustainably through involving local communities. This book highlights the potential of a new methodology of uncovering and stimulating community initiatives in sustainable land management in Africa. Analyses of four contrasting African countries (Ghana, Morocco, South Africa and Uganda) show that as communities directly face the challenges of land degradation, they are likely to develop initiatives themselves in terms of sustainable land management. These initiatives (or 'innovations') may be more appropriate and sustainable than those emanating from research stations located far from the communities. The book describes the rationale of the approach used, the set of steps followed, how the project managed to engage the communities to understand the importance of the activities they were undertaking, and how they were stimulated to improve and extend their initiatives and innovativeness. Examples covered include soil fertility, community forestry, afforestation, water, invasive species and grazing land management. Central to the book is the way communities, and scientists, interacted between the four countries and learnt from each other. The book also shows how the initiatives were outscaled locally.

Book Description
This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.
