Global cropland intensification surpassed expansion between 2000 and 2010: A spatio-temporal analysis based on GlobeLand30
expansion and intensification of agricultural land are two main strategies to increase food production. Here, we investigated the patterns of spatio-temporal global expansion and intensification of agricultural land between 2000 and 2010 using GlobeLand30 dataset. In doing so, we first analyze the expansion and loss of agricultural land globally at different spatial scales. Second, we calculated the intensification of agricultural land from the perspective of output and mapped the spatial distribution globally. Third, nine patterns plus expansion and intensification of agricultural land is identified, and the contribution of these two strategies for global crop production is estimated and compared to end.
The results showed that the global agricultural land increased slightly (2.19%) during 2000-2010, with the Americas have the largest net increase (0.21 million km2) and Africa had the highest amount of increase (7.42%) and spatial the most substantial variation. Among the top ten countries of the world with the largest area of agricultural land, China is the only country that experienced a decrease in agricultural land, while agricultural land in Brazil and Argentina increased the most. In addition, we found that Brazil ranked first in the intensification of agricultural land, followed by China, India and Ukraine.
More than a third of the country’s agricultural land area has a stable and moderate intensification, indicating that the system does not harm the environment farmland globally significant during this period. ten countries (eg, Brazil and Algeria) experienced a significant expansion of agricultural land as well as a high degree of intensification, suggesting that they could be a major contributor to global crop production and environmental changes. expansion of agricultural land is largely driven increase in production plants in Asia, while the intensification of agriculture is a dominant factor for crop production in Europe and America.
Overall, the intensification of agricultural land accounted for more than the expansion of global agricultural production increase during 2000 and 2010. The result we get a comprehensive picture of the spatio-temporal pattern of global agricultural land expansion and intensification, which can provide insight to help the international community and individual countries to guide land use planning better, adjust agricultural structure and coordinate the food trade so as to achieve sustainable development of agriculture.

intensification of heat waves in Australia: A consistent trajectory in the past, present and future
The heat wave is defined as an event of very high temperatures that occur during at least three consecutive days with a large impact on human health, economy, agriculture and ecosystems.
This paper examines: 1) changes in the characteristics of the heat wave as the peak temperature, the number of incidents, frequency and duration during the period of last 67 years in Australia; 2) the projected changes in the characteristics of the heat wave for this century in Queensland, northeast Australia; and 3) the impact of heat waves avoided limiting global warming to 1.5 ° C, 2.0 ° C and 3.0 ° C. The results show that heat waves have increased in intensity, frequency and duration in Australia over the past 67 years, the intensification of such very high in the last few decades. Downscaled projections of future climate for Queensland show that the heat wave will intensify during the current century.

Projections also highlighted that the different climatic zones in Queensland may have a different response to heat waves under global warming, where the tropical and equatorial heat wave seemed more sensitive to atmospheric CO2 concentration increased compared to temperate and arid regions. The results offer new insights to support climate adaptation and mitigation at a regional scale. These findings have been used by healthcare and emergency services to inform policy development across the state to reduce the impact of heat waves.
