The earth might be getting greener

This is from NASA:

greening.png… the greening of the planet over the last two decades represents an increase in leaf area on plants and trees equivalent to the area covered by all the Amazon rainforests. There are now more than two million square miles of extra green leaf area per year, compared to the early 2000s – a 5% increase.

“China and India account for one-third of the greening, but contain only 9% of the planet’s land area covered in vegetation – a surprising finding, considering the general notion of land degradation in populous countries from overexploitation,” said Chi Chen of the Department of Earth and Environment at Boston University, in Massachusetts, and lead author of the study.

China’s outsized contribution to the global greening trend comes in large part (42%) from programs to conserve and expand forests. These were developed in an effort to reduce the effects of soil erosion, air pollution and climate change. Another 32% there – and 82% of the greening seen in India – comes from intensive cultivation of food crops.

On Uganda’s Textile Sector

This is from The Economist:

Uganda’s main advantages, for the moment, are cheap cotton and labour, and preferential access to American and European markets. When exporting to the rich world “Africa has an 18-35% duty advantage over any other continent”, says Nick Earlham, a shareholder in WUCC and in Fine Spinners. “It’s very competitive.”Screen Shot 2017-05-04 at 1.13.26 PM

Textile workers in Kampala earn about $85 a month, compared with $150 in Kenya and $108 in Vietnam, never mind up to $700 in China. But these savings are offset by problems in almost every other sphere. Power cuts keep plunging the factory into darkness, and an erratic supply of steam to the dyeing machines makes it hard to ensure that each batch of fabric looks alike.

Textiles appear to be a low hanging fruit as far as creating mass employment in African states is concerned. And, at least for now, they will remain immune from the threat of mechanization:

Robots are not yet much good at fiddly sewing jobs on floppy fabric; less than 0.1% of the world’s industrial robots are in the clothing trade.

More on this here.

Lastly, while production levels have not increased significantly over the last decade, FAO data (see below) do suggest a non-trivial increase in productivity (yield/ha) in Uganda’s cotton sector. This outcome could be a result of a myriad causes, but it is in line with recent research by Bates and Block (2013) showing increased agricultural productivity in African states that experienced real exposure to competitive electoral politics.
