Designing Landscapes for Performance Based on Emerging Principles in Landscape Ecology
Provedor de dados: 7
Autores: Lovell, Sarah Taylor; University of Vermont; Sarah.Lovell@uvm.edu; Johnston, Douglas M.; Iowa State University; dmjohnst@iastate.edu.
We have proposed a framework for transforming landscapes to improve performance by integrating ecological principles into landscape design.  This effort would focus on the development of multifunctional landscapes, guided by the rapidly growing knowledge base of ecosystem services provided by landscape features.  Although the conventional approach to landscape ecology is based on a model that assumes poor ecological quality in the human-dominated matrix, a review of recent literature reveals important opportunities to improve the quality of the landscape matrix by increasing spatial heterogeneity through the addition of seminatural landscape elements designed to provide multiple ecosystem services.  Taken alone, these individual elements might not appear...

Resumo: Este documento apresenta o jovem rural do Circuito das Frutas como indutor para renovação da agricultura periurbana. Descreve como o jovem se insere no contexto das famílias rurais, quais as limitações para a sua permanência no campo, e quais as possibilidades de dar continuidade a atividade agrícola de seus pais. Relata, também, como ocorre a inserção do jovem rural no movimento dos neorrurais. Para tanto, são apresentados os modos de produção locais para melhor conhecimento sobre a agricultura no Circuito das Frutas.

Low-cost options for reducing consumer health risks from farm to fork where crops are irrigated with polluted water in West Africa.
Provedor de dados: 31
Autores: Amoah,   Philip; Keraita,   Bernard; Akple,   Maxwell; Drechsel,   Pay; Abaidoo,   Robert Clement; Konradsen,   Flemming.
To identify interventions which reduce health risks of consumers where highly polluted irrigation water is used to irrigate vegetables in West Africa, scientists worked over 5 years with farmers, market traders and street food vendors in Ghana. The most promising low-cost interventions with high adoption potential were analyzed for their ability to reduce common levels of pathogens (counts of fecal coliforms and helminth eggs). The analysis showed the combination potential of various interventions, especially on-farm and during vegetable washing in line with the World Health Organization (WHO) guidelines. The tested market-based interventions were important to prevent new or additional contamination.

Consumers’ Willingness to Pay for Food Safety in Nairobi: The Case of Fresh Vegetables
Provedor de dados: 31
Autores: Lagerkvist,   Carl Johan; Hess,   Sebastian; Ngigi,   Marther W.; Okello,   Julius Juma.
Large urban areas in developing countries represent currently the most dynamically growing markets for food products. This study investigates the willingness to pay of consumers in Nairobi for safer leafy vegetables. We survey individuals’ perceived food safety across four major market categories, while also considering the explanatory role of trust and behavioral, psychological, and socio-demographic covariates. Results show that willingness to pay is market-specific and multi-faceted, with trust and perceived risks as important drivers, while income plays only a subordinate role. We conclude that policy makers should aim to reduce asymmetric information within the value chain without raising food prices such that safer vegetables would become...

Provedor de dados: 31
Autores: Wang,   Cheng-yong.
Based on the introduction of the profile of Pearl River Delta area, the strengths, weaknesses, opportunities and threats of developing urban agriculture in Pearl River Delta area are analyzed by using the SWOT analysis. The strengths are analyzed from three aspects, covering the natural resources, geographic advantages and technological advantages; the weaknesses are analyzed from the terms of land resources, labor cost, industrial scale and quality of personnel involved; opportunities are analyzed from the aspects of potential clients, favorable policies and markets; the threats are analyzed from two aspects, including concept factor and income gap between urban and rural areas. on the basis of the above analyses, the countermeasures and suggestions on...

Rural-urban food, nutrient and virtual water flows in selected West African cities
Provedor de dados: 31
Autores: Drechsel,   Pay; Graefe,   Sophie; Fink,   Michael.
Impacts of increasing population pressure on food demand and land and water resources have sparked interest in nutrient and water balances and flows at a range of scales. In IWMI Research Report 115, it was tried for the first time to quantify rural-urban food flows for selected cities in Ghana and Burkina Faso to analyse their dependency on food supplied from rural vs. peri-urban vs. urban farming. Both, the urban nutrient and water footprints are closely interlinked. Currently, 80-95 percent of the domestic water used and the nutrients consumed go to waste without treatment or resource recovery. The economic dimensions are significant. Options to reduce the environmental burden by closing the rural-urban water and nutrient cycles are discussed.

Does Urban Agriculture Enhance Dietary Diversity? Empirical Evidence from a Sample of Developing Countries
Provedor de dados: 31
Autores: Zezza,   Alberto; Tasciotti,   Luca.
Urban agriculture (UA) is defined as the production of crop and livestock goods within city and town boundaries. According to some statistics, 200 million people are employed in UA, contributing to the food supply of 800 million urban dwellers [1]. In African countries, 40 per cent of urban dwellers are said to be engaged in some sort of agricultural activities and this percentage rises to 50 per cent in Latin American countries [2]. If such numbers are accurate UA may play a role in addressing urban food insecurity problems. This paper attempts to fill some of the key research gaps in this area using survey data for 15 developing or transition countries. The paper analyzes in a comparative perspective the importance of UA for the poor and food insecure...

Urban Agricultural Development from the Perspective of Circular Economy－An Analysis of Sino-Singapore Eco-city Model in Tianjin
Provedor de dados: 31
Autores: Zhang,   Tian-yi; Jin,   Yan-ping.
The connotation and development of circular economy and circular agriculture are illustrated from the perspective of circular economy. Take the duplicable Sino-Singapore Eco-City in Tianjin as a case to analyze the background, significance and features of building Sino-Singapore Tianjin Eco-City and point out the sustainable developmental orientation of the “three harmony and three capabilities” as well as its inspiration on the development of Tianjin urban agriculture from the aspects of water-saving, land-saving and energy-saving. Under the direction of circular economy theory, the enhancement of economical utilization of agricultural resources and resource utilization of agricultural wastes has positive effects on improving urban environment:...
