Benefits of SLCP controle measures for Agriculture
Implementation of the 16 control measures specified in the Time to Act publication is expected to have significant benefits for agriculture worldwide. Rapid reduction of methane and sot has the potential to avoid an annual loss of over 50 metric tonnes of crop yields per year by 2030.

Effects on Agriculture - SLCPs, a Threat to Agricultural Productivity
SLCPs, especially tropospheric O3, detrimentally impact ecosystems including crop yields, and are affecting food security. Present day global relative yield losses due to tropospheric O3 exposure has been estimated for four major crops and range between 7-12% for wheat, 6-16% for soybean, 3-5% for rice and 3-5% for maize.

Soy Expansion in the Brazilian Amazon frontier
Often, small-scale farmers settle the areas along logging roads in order to burn secondary or cleared forest for crop production. These farmers are eventually pushed or bought-out by large-scale cattle ranchers or soy prodcution owners.

Climate scenarios for cereal production
The figure shows change in cereals production under three different GCM equilibrium scenarios (percent from base estimated in 2060). While there are still uncertainties about whether climate change will cause global agricultural production to increase or decrease, changes in the aggregate level of production are expected to be small or moderate. The result of the studies that have been conducted so far vary depending on such variables as the trad...

Women in government decision-making positions in 1998
Women are responsible for most household work (and in many parts of the world the majority of agricultural production), but women’s rights to own land or control resources are constrained, often by traditional customs and religious laws.

Projected land use changes
A central component in preventing loss of biodiversity and
ecosystem services, such as provisioning of water, from
expanding agricultural production is to limit the trade-off
between economic growth and biodiversity by stimulating
agricultural productivity and more efficient land use. Further
enhancement of agricultural productivity (‘closing the
yield gap’) is the key factor in reducing the need for land
and, consequently, the rate of bio...

The disappearance of the Aral Sea
The demise of the Aral Sea in central Asia was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers to provide irrigation water for local croplands. These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear completely by 20...
