Book Description
Greenhouses and shelter structures for tropical regions is a manual in the series of technical papers prepared by the FAO Horticultural Crops Group, Crop and Grassland Service, Plant Protection Division. The text provides technical guidelines for the design and construction of simple and low-cost shelter structures in the tropics and also reviews the cultivation practices to be applied for sustainable and intensified crop management under these greenhouses structures. There is a range of possibilities depending on the crop requirements, the specific climate conditions of the area, marketing considerations and financial parameters. Detailed technical specifications are given, including drawings, illustrations and diagrams of various construction types. Contents Chapter 1: Introduction; Chapter 2: Climates of tropical regions; Climatic elements, Solar radiation, Temperature, Precipitation, Evapotranspiration, Storms, Classification of climates, Equatorial zone, Sub-tropical(C), Dry climates (B), Highlands; Chapter 3: Problems and Possibilities for vegetable production; Chapter 4: Construction and covering material; Requirements, Ar: Tropical wet climates, Aw: Tropical wet and dry climates, Cf: Sub-tropical humid, Dry climates, Tropical highlands, Cs: Sub-tropical dry summer/ mediterranean, Constructions, Design criteria, Greenhouse constructions, Materials for greenhouses construction, Constructions for tropical wet (Ar) and tropical wet and dry (Aw) climates, Constructions for sub-tropical (Cf) climates and higlands (H), Shade houses, Covering materials, fastening and stretching of covering materials, Windbreaks; Chapter 5: Ventilation and cooling; Ventilation, Cooling, Pad efficiency, Pad material and pad thickness, Pad area and fan-to-pad distance, Pad location, Fans, Operation of fan and pad systems, Air-flow rate, Water-flow rate; Chapter 6: Crop-water requirements and rainwater storage; Crop-water requirements, Calculation of storage volume, Design of storage volume, Design of storage basins, Earth basin, Earth basin with plastic films, Earth basin with lining of concrete blocks and plastic film, Concrete basin.

Book Description
This book equips readers with a deeper understanding of the challenges posed by radical socioeconomic, environmental, and cultural changes due to globalization and describes effective, sustainable solutions to these challenges. The focus is especially on the rapid urbanization processes in countries of the Global South, which are giving rise to dramatic new problems of spatial and social inequality and difficult environmental challenges in relation to climate change. Readers will gain skills and knowledge that will help them to develop an integrated, multidisciplinary approach to planning, design, and management of urban settlements and territories in contexts with a high level of social, economic, territorial, and landscape vulnerability. The coverage includes, for example, strategies to promote social inclusion, improve housing quality, ensure adequate education, protect cultural heritage, enhance risk management, and address issues in the food-energy-water nexus. Among the authors are leading experts from the Polytechnic University of Milan, where a multidisciplinary set of studies and research projects in the field have been undertaken in recent years.

Book Description
The projected increase in world population levels and the subsequent rise in food demand represents a huge challenge for agricultural production systems worldwide. This publication examines the opportunities and challenges raised by the use of plant genetic resources and highlights the contribution that data from multi-environment yield trials can provide for the definition of adaptation strategies and yield stability targets in plant breeding programmes. It contains a case study about a durum wheat crop programme in Algeria, and also includes a CD-ROM with data from IRRISTAT, a programme developed by the International Rice Research Institute (IRRI).

Book Description
During the meeting the FAO Panel of Experts was responsible for reviewing pesticide use patterns (good agricultural practices), data on the chemistry and composition of the pesticides, and methods of analysis for pesticide residues as well as for estimating the maximum residue levels that might occur as a result of the use of pesticides according to good agricultural practices. The WHO Toxicological Core Assessment Group was responsible for reviewing toxicological and related data and for estimating, where possible, acceptable daily intakes (ADIs) of the pesticides for humans. This report contains information on ADIs, maximum residue levels and general principles for the evaluation of pesticides. The supporting documents (on residues and toxicological evaluations) contain detailed monographs on these pesticides and include comments on analytical methods

Book Description
This book is the third of four dealing with bioclimatic design and construction by focusing on the most basic and polyvalent of modern environmental systems: the bioclimatic greenhouse, the "Swiss-army chainsaw" of architecture. More specifically, this third volume focuses on how the envelope of bioclimatic wooden greenhouses may be designed and built. In more general terms, it helps us to consider how to design and build the transparent and opaque enclosures of bioclimatic, low-energy architecture, with low environmental impact. This multi-volume book covers both free-standing greenhouses that can naturally heat and cool themselves, and lean-to greenhouses that support the natural heating and cooling of buildings; this includes both agricultural greenhouses and greenhouses suited to host people. As a result, it is a trans-disciplinary work deriving its areas of concern from a broad range of study areas, spanning from environmental, to constructional, to structural, drawing the clarity of the approach from the fact that the topics are presented by a single author with a single voice and a designer's mindset. To achieve this, the book adopts a composite set of explanatory strategies and communication registers – including extensive support by 3D construction drawings and examples – and presents not only stateof-the-art solutions, but also experimental ones.
