Why is urban agriculture important?• The Issue: urbanization and poverty growth in a deteriorating 

environment– Half the world’s population now lives in towns or cities and by 2020, this 

is expected to rise to 60%. implications for the situation of food security, poverty, and unemployment in these regions, which typically lack infrastructure and experience economic and political instability

• The Response: an integrated agricultural research response– Pool research knowledge and resources at national and international 

levels to better understand and address the complex interplay of food security, income needs, and the ecological, social, and institutional particularities of towns and cities. 

• The Consultative Group on International Agricultural Research (CGIAR) is a unique global partnership for agriculture with 15 food and environmental research centers around the world which it supports referred to as Future Harvest. 

• Several Future Harvest research centers have already implemented research projects in urban and peri‐urban agriculture.

About Urban Harvest

• Launched in 1999 by the CGIAR initiative to direct and coordinate the collective knowledge and technologies of the Future Harvest Centers towards strengthening urban and peri‐urban agriculture (UPA). 

• The Initiative, formerly known by its acronym SIUPA, and now renamed Urban Harvest, helps Centers link together their own efforts and become partners with many national and international efforts.

The goals of Urban Harvest 

• Contribute to enhanced food security, improved nutrition and higher incomes for poor urban and peri‐urban families

• Reduce the negative environmental impact of UPA and enhance its positive potential for sustainability

• Establish the perception of UPA as a productive, essential component of sustainable cities 

Page 7: Geospatial analytical applications in Urban Harvest ... · Outcome oriented geospatial applications in research; Urban Harvest experiences Shuaib Lwasa Research Scientist. Urban Harvest‐International

Research Framework

• Research framework focuses on three essential themes in UPA which provide the basis for guiding activities at the practical level of research and development projects in regional settings, as well as in alliance‐building initiatives at global and regional level.

Research Framework

Page 9: Geospatial analytical applications in Urban Harvest ... · Outcome oriented geospatial applications in research; Urban Harvest experiences Shuaib Lwasa Research Scientist. Urban Harvest‐International

Urban livelihoods and markets: research questions

• What are the livelihoods contributions of urban and peri‐urban agriculture?

• How can rural‐urban resource flows and markets bring bigger benefits to poor rural and urban households?

• Changes in which factors of production offer the best route to profitability and sustainability of urban  production systems?  

• What key opportunities exist for better integrating crop and livestock agro‐enterprises with each other and with urban markets?

• What does local agriculture contribute to urban nutrition?

Page 10: Geospatial analytical applications in Urban Harvest ... · Outcome oriented geospatial applications in research; Urban Harvest experiences Shuaib Lwasa Research Scientist. Urban Harvest‐International

Stakeholder and policy analysis, dialogue: research questions

• What are the key interests, knowledge and demands of types of stakeholders vis a vis urban agriculture? 

• What positive and negative effects do urban institutions/ policies have on agriculture? 

• What kinds of dialogue, stakeholder platforms and interventions contribute to structural and policy change? 

• What urban resource use models can improve integration of UA in policy and planning?

Page 11: Geospatial analytical applications in Urban Harvest ... · Outcome oriented geospatial applications in research; Urban Harvest experiences Shuaib Lwasa Research Scientist. Urban Harvest‐International

Urban ecosystem health: research questions

• What are the contaminant and disease pathways affecting humans which involve UA?

• What are the risks/benefits of liquid and solid waste use? 

• How can contaminants and zoonoses be managed?• What are the effects of changing urban NR use on agriculture?

• How can UPA contribute to a healthier urban environment? 

• How can use of organic wastes in UPA be improved?
