Book Description
Design of Diversion Weirs Small Scale Irrigation in Hot Climates Rozgar Baban In most developing countries, it is now realised that the most important factor in the success of the agricultural sector is the sustainability of irrigation projects. Diversion weirs are the most important components of these projects. The aim of this book is to teach step by step how to design diversion weirs. It encompasses all technical subjects required: site investigation, hydrological, hydraulic and structural analysis. Many numerical examples show how to relate engineering theories to applications. Cover illustration A diversion weir in Tanzania constructed by the farmers with technical assistance from the government.

Book Description
Farming Systems Research has three core characteristics: it builds on systems thinking, it depends on the close collaboration between social and biophysical sciences, and it relies on participation to build co-learning processes. Farming Systems Research posits that to contribute towards sustainable rural development, both interdisciplinary collaborations and local actor engagement are needed. Together, they allow for changes in understanding and changes in practices. This book gives an overview of the insights generated in 20 years of Farming Systems Research. It retraces the emergence and development of Farming Systems Research in Europe, summarises the state-of-the-art for key areas, and provides an outlook on new explorations, especially those tackling the dynamic nature of farming systems and their interaction with the natural environment and the context of action.

Book Description
Bachelor Thesis from the year 2008 in the subject Agrarian Studies, grade: A, , course: RURAL DEVELOPMENT AND AGRICULTURAL EXTENTION, language: English, abstract: The research was intended to answer the following questions: 1. What are the factors impeding adoption of small scale irrigation? 2. What are the problems contributing for less participation of farmers on small scale irrigation? 3. What are possible solutions to improve community participation on irrigation? Agriculture is the major primary economic activities of the Ethiopian population. Due to the existence of diversified topography, soil, weather and climatic conditions that favor agricultural activities the majority of the Ethiopian population have been engaged in and generate their income from the sector. However, agriculture in Ethiopia is mainly characterized by the use of backward & traditional farm implements and subsistence farming system dominates by rain fed agricultural production that resulted to low and declining productivity of the sector. The use of supplementary irrigation from either traditional or modern water harvesting structures is considered by the government.

Book Description
This volume brings together a diverse set of new studies--archaeological, ethnohistoric, and ethnographic--that focus on agricultural intensification and hydraulic systems around the world. Fifteen chapters--written by many of the world's leading experts--combine extensive regional overviews of agricultural histories with in-depth case studies. In this volume are chapters on agriculture in the Middle East, South Asia, Europe, Oceania, Mesoamerica, and South America. A wide range of theoretical perspectives and approaches are used to provide a framework for agricultural land-use and water management in a variety of cultural and historical contexts. This book covers the co-evolutionary relationships among sociopolitical structure, agriculture, land-use, and water control. Agricultural Strategies is an invaluable resource for those engaged in ongoing debates about the role of intensification and agriculture in the past and present.

Book Description
Nutrient-balance assessments are valuable tools for delineating the consequences of farming on soil fertility. Various approaches and methods for different situations have been used in the past. This bulletin presents a state-of-the-art review of nutrient balance studies. It brings out the evolution of the approaches and methods, provides for comparisons among them, features the improvements made, and highlights remaining issues. This analysis will be useful in further development of the assessment methodologies as reliable tools for devising time-scale soil fertility management interventions.
