“…Agricultural production and land use change generate about one third of the greenhouse gases (GHGs) emissions worldwide and are among the key drivers of global warming [100]. If one considers the entire food system-from field to fork to landfill-this is a conservative estimate.…”

The UN's 2030 Agenda for Sustainable Development, and the transition from Millennium Development Goals (MDGs) to Sustainable Development Goals (SDGs), heralds an important turn in global sustainability policy. With implementation now taking place in all countries, regardless of GDP, a key question is how affluent governments in large metropolitan areas can effectively contribute to global sustainable development. This paper argues that urban food systems strategies-a relatively new tool in local policymaking in the Global North-have the potential to amplify and consolidate national and international efforts in this direction and facilitate a more synergistic approach to SDG implementation. An in-depth comparative analysis of the 2030 Agenda and the sustainable food systems strategies of five of the ten largest cities in North America-New York, Philadelphia, Los Angeles, Chicago, and Toronto-helps to uncover key gaps and areas of convergence between goals, objectives, and evaluation frameworks. Goal-and indicator-level analyses cast light on promising areas for cross-jurisdictional cooperation and suggest that, while not without limitations, urban food systems strategies offer manifold pathways to streamline global, national, and local implementation efforts and effectively forward the 2030 Agenda over the next decade.

“…In particular, albedo and roughness length are well known for their influence on the surface energy balance and wind, affecting not only the amount of precipitation but also its spatial distribution at the local scale (Pielke and Avissar, 1990;Pielke, 2001;Pielke et al, 2007a;Pielke et al, 2007b;Werth and Avissar, 2002; Silva ). Adjacent patches that differ at P < 0.05 are separated by a thin black line Dias, 2006;Mahmood et al, 2013;Pielke et al, 2016). The replacement of forests and grasslands by farmlands caused an overall reduction of precipitation as high as 100 mm month -1 in Eastern Paraguay and widespread increases and decreases of the order of 50 mm month -1 in Western Paraguay (Figure 5f).…”

“…Changes in land cover imply changes in the biophysical properties of the surface, such as albedo, leaf area, roughness length, root depth, stomatal resistance, and other properties that depend on the land-cover type. Changes in vegetation traits can affect the exchange of momentum, heat, and moisture between the atmosphere and the underlying surface, and thus influence climate at different spatial and temporal scales (Pielke and Avissar, 1990;Pielke et al, 2007b;Mahmood et al, 2013;Pielke et al, 2016). Although these effects may go unnoticed in the global average, they can be significant at regional scales because they directly affect the patterns of rainfall and temperature as well as air circulation processes (Pielke, 2001;Werth and Avissar, 2002;Silva Dias, 2006;Mahmood et al, 2013;Pielke et al, 2016).…”

Abstract:Land-use change poses a major threat over much of the La Plata River Basin in South America. Paraguay, with one of the highest deforestation rates in the region, has experienced rapid loss of its natural forests. Such landscape transformation implies changes in vegetation traits that affect exchange of momentum, heat, and moisture between the surface and atmosphere. To understand how the regional climate of Paraguay could be affected by the deforestation that occurred between 1990 and 2000, we ran 1-month long simulations for each November during the 2006-2012 period for a control scenario and a past vegetation scenario. Climate responses to land-cover change differed with location and vegetation. In eastern Paraguay, replacement of forest with farmland increased albedo, leading to an overall lower latent heat and both lower and higher sensible heat fluxes. In western Paraguay, replacement of grassland with farmland slightly increased albedo, reducing the sensible heat and increasing evapotranspiration owing to greater surface soil wetness. Effects of land-use change on precipitation are more likely to change local patterns of precipitation than they are the country's total monthly precipitation.

“…But its main climate role is to diminish the greenhouse effect by the large amounts of carbon it stores. Vegetation acts also by evapotranspiration [6]: the humidity that forest delivers to the atmosphere (Figure 1) favours regional rainfalls, a phenomenon which contributed to the "green Sahara" 6000 years ago (Figure 2). A stronger evapotranspiration has also a cooling effect on the surface.…”
