  • Algae and their Biotechnological Potential

    Algae are important organisms that include seaweeds and a number of single-celled and multicellular microscopic forms. Algae are ubiquitous; they inhabit almost everywhere including oceans, freshwater bodies, rocks, soils, and trees. Man's uses of algae may date back to ancient times. In recent decades, there has been renewed interest in the ...

  • Unlocking the water potential of agriculture (En)

    Series: Non-series TitlesAll statistical evidence confirms that agriculture is the key sector for water management, now and in the next decades. Nevertheless, the rural water development sector fails at present to get priority, compared to other competing sectors, in international fora. Strong and new arguments are needed to bring rural water back ...

  • The Fish Production Potential of the Baltic Sea

    It presents a new approach to set fish quota based on holistic ecosystem modeling (the CoastWeb-model) and also a plan to optimize a sustainable management of the Baltic Sea including a cost-benefit analysis. This plan accounts for the production of prey and predatory fish under different environmental conditions, professional fishing, ...

  • Strategic reassessment of fish farming potential in Africa (A) (En)

    Series: CIFA Technical Papers(Reprint. First published in 1998) The present study is an update of an earlier assessment of warm-water fish farming potential in Africa, by Kapetsky (1994). The objective of this study was to assess locations and areal expanses that have potential for warm-water and temperate-water fish farming in continental Africa. ...

  • Modelling water and nutrient dynamics in soil-crop systems

    Soil-crop-atmosphere interactions play a central role in the multiple functions of rural landscapes. Agro-ecosystem models are increasingly used to support decision making on different scales towards sustainable land use and management.This is accompanied by a demand of model users for model validation to get an idea about the reliability of ...

  • Integrated irrigation and aquaculture in West Africa. Concepts, practices and potential (English)

    This volume contains background documents and papers presented at the FAO-WARDA Workshop on Integrated Irrigation Aquaculture (IIA) held in Bamako, Mali, from 4 to 7 November 2003, as well as the findings of FAO expert missions on IIA in the West Africa region. The rationale for IIA development lies in its potential to increase productivity of ...

  • Fingerponds: Seasonal Integrated Aquaculture in East African Freshwater Wetlands: Exploring their potential for wise use strategies: PhD: UNESCO-IHE Institute, Delft

    Wetlands play an important role in the livelihoods of many rural households particularly in sub-Saharan Africa. However, due to decline in rainfed terrestrial agriculture, many wetlands are being encroached upon to grow crops. The question to any wetland scientist/policy maker in the region is: what efforts can be made to achieve a balance between ...

  • Soil Biological Fertility

    This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It demonstrates the interdependence of soil biological fertility with physical and chemical characteristics of soil. The book highlights the enormous diversity of life in soil and the resulting ...

  • Agriculture Practices and Policies for Carbon Sequestration in Soil

    The potential to mitigate greenhouse gas emissions and global climate change is one factor driving agricultural policy development of programs that might pay farmers for practices with a high potential to sequester carbon. With chapters by economists, policy makers, farmers, land managers, energy company representatives, and soil scientists, ...

  • Economics of soil productivity in sub-Saharan Africa, (The) (En)

    Series: Non-series titlesThe increased degradation and declining fertility of sub-Saharan African soils have been recognized as critical factors in food security and poverty alleviation. This study examines the current and potential role of economic in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the ...

  • Guidelines for soil description. Fourth edition (En)

    Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management ...

  • Plant-Induced Soil Changes: Processes and Feedbacks

    This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential ...

  • Experiences of Farmer Participation in Soil Fertility Research in Southern Zimbabwe

    This working paper discusses the impact of a multi-institutional research programme in low potential areas of Kenya. The programme elaborated nutrient balances, combined with economic analysis, to better understand causes and effects of soil fertility decline. Alongside, better soil fertility management practices were developed using a ...

  • Soil Quality, Sustainable Agriculture and Environmental Security in Central and Eastern Europe

    Agriculture is a crucial component of the economies of many of the countries in transition from a centrally-planned to a market economy and the sector is by no means immune to the environmental and socioeconomic problems confronting the countries as a whole. The concept of sustainable development provides a convenient framework for the ...

  • Storing Carbon in Agricultural Soils: A Multi-Purpose Environmental Strategy

    Soil carbon sequestration can play a strategic role in controlling the increase of CO2 in the atmosphere and thereby help mitigate climatic change. There are scientific opportunities to increase the capacity of soils to store carbon and remove it from circulation for longer periods of time. The vast areas of degraded and desertified lands ...

  • Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

    This book is a comprehensive and updated review of fundamental studies on inhibition of soil urease activity and of applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years and the patent literature comprises a period of nearly 40 years. The potential ...

  • Belowground Responses to Rising Atmospheric CO2: Implications for Plants, Soil Biota, and Ecosystem Processes

    As atmospheric CO2 increases there will almost certainly be alterations in soil carbon fluxes. It is likely that such alterations will be accompanied by changes in the partitioning of carbon between organic structures and to soil processes. These changes have the potential for further altering the structure and function of terrestrial ...

  • Salinity and Water Stress

    Salinity and water stress limit crop productivity worldwide and generate substantial economic losses each year, yet innovative research on crop and natural resource management can reveal cost-effective ways in which farmers can increase both their productivity and their income.Presenting recent research findings on salt stress, water stress and ...
