This paper offers a critical assessment of the value and utility of the evolving City Region Food Systems (CRFS) approach to improve our insights into flows of resources-food, waste, people, and knowledge-from rural to peri-urban to urban and back again, and the policies and process needed to enable sustainability. This paper reflects on (1) CRFS merits compared to other approaches; (2) the operational potential of applying the CRFS approach to existing projects through case analysis; (3) how to make the CRFS approach more robust and ways to further operationalize the approach; and (4) the potential for the CRFS approach to address complex challenges including integrated governance, territorial development, metabolic flows, and climate change. The paper begins with the rationale for CRFS as both a conceptual framework and an integrative operational approach, as it helps to build increasingly coherent transformational food systems. CRFS is differentiated from existing approaches to understand the context and gaps in theory and practice. We then explore the strength of CRFS through the conceptual building blocks of 'food systems' and 'city-regions' as appropriate, or not, to address pressing complex challenges. As both a multi-stakeholder, sustainability-building approach and process, CRFS provides a collective voice for food actors across scales and could provide coherence across jurisdictions, policies, and scales, including the Milan Urban Food Policy Pact, the Sustainable Development Goals, the Habitat III New Urban Agenda, and the Conference of the Parties (COP) 21. CRFS responds directly to calls in the literature to provide a conceptual and practical framing for policy through wide engagement across sectors that enables the co-construction of a relevant policy frame that can be enacted through sufficiently integrated policies and programs that achieve increasingly sustainable food systems.
Abstract:In the context of growing urbanisation, urban poverty, and climate change impacts, the importance of urban food security and urban food systems is increasingly recognised by both local and national governments, as well as international actors. There is also a growing understanding that urban development and food systems cannot be decoupled from rural development given the multiple impacts that urban areas have on their surroundings. In recent years the concept of City Region Food Systems (CRFS) has emerged as a promising approach to support local governments, policy makers, and multi-stakeholder bodies in making informed decisions to improve urban and regional food system sustainability and resilience, while taking into account a more integrated approach to territorial development across urban and rural areas. This paper is based on an ongoing FAO and RUAF programme of assessing and planning City Region Food Systems, currently implemented in eight city regions in Canada, Colombia, Ecuador, Senegal, Sri Lanka, The Netherlands, and Zambia. The paper analyses the content, definition and delimitations of the concept of City Region Food Systems by presenting two case studies from Latin America (Quito and Medellín), and discusses first advances in policy uptake and territorial food planning.
Land degradation and soil fertility deterioration are two of the main causes of agricultural production stagnation and decline in many parts of the world. The model of crop production based on mechanical soil tillage and exposed soils is typically accompanied by negative effects on the natural resource base of the farming environment, which can be so serious that they jeopardize agricultural productive potential in the future. This form of agriculture is destructive to soil health and accelerates the loss of soil by increasing its mineralization and erosion rates. Conservation agriculture, a system avoiding or minimizing soil mechanical disturbance (no-tillage) combined with soil cover and crop diversification, is considered a sustainable agro-ecological approach to resource-conserving agricultural production. A major objective of tillage is supposed to be weed control, and it does not require very specific knowledge because soil inversion controls (at least temporarily) most weeds mechanically (i.e., by way of burying them). However, repeated ploughing only changes the weed population, but does not control weeds in the long term. The same applies to the mechanical uprooting of weeds. While in the short term some tillage operations can control weeds on farms, tillage systems can increase and propagate weeds off-farm. The absence of tillage, under conservation agriculture, requires other measures of weed control. One of the ways in which this is realized is through herbicide application. However, environmental concerns, herbicide resistance and access to appropriate agro-chemicals on the part of resource-poor farmers, highlight the need for alternative weed control strategies that are effective and accessible for smallholders adopting conservation agriculture. Farmers in semi-arid regions contend with the additional challenge of low biomass production and, often, competition with livestock enterprises, which limit the potential weed-suppressing benefits of mulch and living cover crops. This paper reviews the applicability and efficacy of various mechanical, biological and integrated weed management strategies for the effective and sustainable management of weeds in smallholder conservation agriculture systems, including the role of appropriate equipment and prerequisites for smallholders within a sustainable intensification scenario.Keywords: smallholder farming; conservation agriculture; sustainable and ecological weed management; preventive; cultural and direct control methods of weed management
Using examples from the COVID-19 pandemic, this paper reviews the contribution a City Region Food Systems (CRFS) approach makes to regional sustainability and resilience for existing and future shocks including climate change. We include both explicit interventions under United Nations Food and Agriculture Organization (FAO-RUAF) led initiatives, as well as ad hoc efforts that engage with elements of the CRFS approach. To provide context, we begin with a literature review of the CRFS approach followed by an overview of the global food crisis, where we outline many of the challenges inherent to the industrial capital driven food system. Next, we elaborate three key entry points for the CRFS approach—multistakeholder engagement across urban rural spaces; the infrastructure needed to support more robust CRFS; system centered planning, and, the role of policy in enabling (or thwarting) food system sustainability. The pandemic raises questions and provides insights about how to foster more resilient food systems, and provides lessons for the future for the City Region Food System approach in the context of others shocks including climate change.
