Описание: These guidelines outline the process for preparing a National Plan for Conservation and Sustainable Use of Farmers’ Varieties/Landraces, in support of national authorities seeking to develop a systematic approach to the management of these genetic resources. They focus on the common elements required to ensure a systematic, national approach to conservation and sustainable use of farmers’ varieties/landraces.
The cultivation of diverse farmers' varieties/landraces, which tend to be well-adapted and suited to local production systems, confers increased resilience for crop production. Unfortunately, many of these genetic resources have been replaced by modern cultivars in recent decades, resulting in a reduction in the number of varieties grown and/or loss of heterogeneity. Such losses make farming systems less resilient, especially to shocks from abiotic and biotic stresses.
These guidelines will contribute to addressing this continuing loss of diversity. They are a useful tool for development practitioners, researchers, students and policymakers who work on the conservation and sustainable use of these valuable resources.

Название: Developing Sustainable Value Chains for Small-scale Livestock Producers ISBN: 9251317186 ISBN-13(EAN): 9789251317181 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 44350.00 T Наличие на складе: Нет в наличии. Описание: A practical tool for implementing the sustainable food value chain framework with a focus on small-scale livestock producers, targeting an audience of project design teams and policymakers.
The demands placed on land, water, energy and other natural resources are exacerbated as the world population continues to increase together with the expectations of economic growth. This, combined with concerns over environmental change, presents a set of scientific, policy and management issues that are critical for sustainability.
Resource Accounting for Sustainability Assessment: The nexus between energy, food, water and land use offers an approach for multi-scale, integrated assessment of this nexus. It presents a comprehensive and original method of resource accounting for integrated sustainability assessments. The approach is illustrated with three detailed case studies: the islands of Mauritius, the Indian state of Punjab, and the energy economy of South Africa. The relationships between flows of goods, services and materials in these case studies offer valuable insights. The book provides a much needed quality control on the information used in deliberative processes about policy and planning activities.
This innovative book will be of interest to researchers, students and practitioners in the fields of sustainability science, international development, industrial ecology, sustainable resource management, geography and ecological economics.

Описание: Farmers use antibiotics to treat, prevent, and control animal diseases and increase the productivity of animals and operations. However, there is concern that routine antibiotic use in livestock will contribute to antimicrobial-resistant pathogens, with repercussions for human and animal health. Given these concerns, pressure to limit antibiotic uses for purposes other than disease treatment is mounting. Changes in use will lead to a series of adjustments in animal agriculture as producers change production practices, with potential repercussions for prices and volumes in livestock markets. This book addresses the following questions: How widely are antibiotics used in the livestock industries? How could the current structure of the livestock industry influence the effects of restrictions on certain uses of antibiotics? How might the restriction of antibiotics affect production and costs at the animal and farm levels? How might those impacts affect production and prices in markets?

Название: Agricultural Production and Groundwater Conservation: Examples of Good Practices in Shanxi Province, People`s Republic of China ISBN: 9292576135 ISBN-13(EAN): 9789292576134 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 17550.00 T Наличие на складе: Невозможна поставка. Описание: Climate change and declining water resources threaten food production systems worldwide, increasing the need for efficient agricultural processes. The Shanxi Province of the People’s Republic of China has been experiencing declining groundwater tables since 1956. This publication provides examples of how ADB’s development support met the rising challenges in water security, food production, and climate change faced by communities in the Shanxi Province, which resulted to reduced farm labor, increased crop yields, and efficient water usage.

With growing water scarcity in many parts of the world and projections that indicate the need to increase agricultural production and, concurrently, agricultural water use, it is increasingly advocated to focus efforts on improving agricultural water productivity and efficiency--and thus achieve more crop per drop. Many international organizations concerned with water management are also promoting these efforts, and significant public and private investments are being made in both developed and developing countries. Yet some serious problems are associated with this approach. They include conceptual issues, the methods used for measuring agricultural water productivity and efficiency, and the application of these concepts and methods in different contexts--all of which influence the choice of interventions and the evaluation of their implementation. The report aims to shed further light on these issues: first, by clarifying some of the underlying concepts in the discussion of agricultural water productivity and efficiency; second, by reviewing and analyzing the available methods for assessing water productivity and efficiency, including single-factor productivity measures, total factor productivity indices, frontier methods, and deductive methods; and, third, by discussing their application and relevance in different contexts. As a background for this analysis, the report highlights the central role of water use in irrigated agriculture and its link with increasing water scarcity. An underlying framework of the analysis is the view of the water economy transitioning from an expansionary to a mature phase. The report further develops this framework to reflect water management issues in irrigated agriculture. The framework is then applied to make the case that, with increasing water scarcity, the ongoing efforts for improving agricultural water productivity and efficiency need to move beyond crop per drop approaches, because they are in many circumstances an insufficient and sometimes counterproductive attempt to adapt agricultural water management to a maturing water economy.
Water demand in southern Africa continues to rise, as urban areas expand and as agricultural water demand rises to meet the millennium development food security goals. Water resource availability in the northern Limpopo Basin has declined over the last 30 years, and will decline further under climate change. In this study, water resources modelling is used to quantify the effect of water resources strategies and climatic conditions on water resources availability. This is coupled with water balance modelling to evaluate the potential of alluvial aquifers, which form the beds of sand rivers.
The greatest benefit for the least impact comes from strategies providing for better land and soil/water management, such as changing from maize to small grains, production of livestock fodder and conservation agriculture. Small dams are a key resource to rural communities, and change to Multiple Use Systems through abstraction of water for irrigation has clear benefits locally. There is also great potential for the exploitation of alluvial aquifers for water supply. Better management of existing large dams, together with conjunctive use of alluvial groundwater and several reservoirs could increase productive use of water and significantly improve livelihoods without the construction of new reservoirs.

Описание: In A Tale of Three Thirsty Cities: The Innovative Water Supply Systems of Toledo, London and Paris in the Second Half of the Sixteenth Century, Chaim Shulman presents an analysis of three projects of urban water supply systems carried out between 1560s–1610s. The technical and economic differences between these projects resulted from external conditions not directly related to the water supply problem. Although the same basic technology was apparently available at the time in all cases, the geographical, engineering, entrepreneurial and cultural nature of each region differed. The inhabitants’ wellbeing improvement achieved varied accordingly. Much broader insights are drawn on the policies of the three monarchies regarding the initiative of and support for grand scale public works in general.
