As Mozambique’s rivers dry up, the hopes of a harvest evaporate too


flash back story on the negative effects of drought.

For the second year running, Mbalavala’s maize fields, which should have been planted months ago, lie empty; the soil in vegetable gardens is like sand and what little water there is from an emergency borehole must be shared between cattle and people.
Vascos Jaima Chilande, the Mbalavala headman, lists the rivers that nearby villagesusually dam to collect water. “Bambene, Matlavane, Gomaje, Chichaquare … They have all dried up. The government dug a borehole 150 metres deep, but it is not enough. Today there is water only for the animals.”

Indian drought ‘affecting 330 million people’ after two weak monsoons


A flashback story on climate change and drought.

About 330 million people are affected by drought in India, the government has said, as the country reels from severe water shortages and desperately poor farmers suffer crop losses.

A senior government lawyer, PS Narasimha, told the supreme court that a quarter of the country’s population, spread across 10 states, had been hit by drought after two consecutive years of weak monsoons.

India records its hottest day ever as temperature hits 51C (that’s 123.8F)


A flaskback story on the negative effect of climate change and drought

Several hundred people are thought to have died during this year’s heatwave and some areas have banned daytime cooking in order to limit the fire risk.

More than a thousand people died during a heatwave in 2015, mainly caused by dehydration in the southern part of the country.

India declares a heatwave when the maximum temperature hits 45 degrees Celsius, or five degrees higher than the average for the area in previous years.

2016 Asia summer forecast: Drought to ease in India; La Nina to suppress typhoons in West Pacific


Flash back trending story on drought.

El Niño is defined by above-average sea-surface temperatures in the eastern and central equatorial Pacific Ocean. These sea-surface temperatures cycle from warm to cool, relative to average, over a several-year period. When the sea-surface temperatures in the same area of the Pacific Ocean are cooler than average for a few months, a La Niña pattern has developed.

“El Niño will transition to neutral conditions early this summer, then perhaps toward a weak La Nina during August or September,” according to AccuWeather Chief International Meteorologist Jason Nicholls. “Because of this and other factors, we expect rainfall to return toward average over a large part of India, Malaysia and Indonesia.”

Across Africa, the worst food crisis since 1985 looms for 50 million


Flash back story on drought

Harvest should be the time for celebrations, weddings and full bellies in southern Malawi. But Christopher Witimani, Lilian Matafle and their seven children and four grandchildren had nothing to celebrate last week as they picked their meagre maize crop.

Last year’s drought, followed by erratic rains, hit the village of Nkhotakota hard. But this year the rains never came and, for a second year running, the family grain store is empty. If they manage their savings carefully and eat just one small meal a day, they may just have enough food for two more months.

The Next Migrant Wave


MANILA – Imagine that you are a farmer. Your crops are withering as weather patterns become more volatile, your well water is too salty to drink, and rice is too expensive to buy at the market. So, you leave home in search of a better life.

Millions of people in vulnerable communities around the world do not have to imagine such a scenario. They are living it now, as an increasingly unpredictable climate takes its toll; and their numbers are likely to soar as the effects of climate change intensify.

Maximum Power Point Tracking (MPPT)



Solar cells have a complex relationship between temperature and total resistance that produces a non-linear output efficiency which can be analyzed based on the I-V curve.[6][7] It is the purpose of the MPPT system to sample the output of the PV cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.[8] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors.

Solar Pump. Maximum power point tracking


* curated information from WikipediA
Maximum power point tracking[1][2] (MPPT or sometimes just PPT[3][4]) is a technique used commonly with wind turbines and photovoltaic (PV) solar systems to maximize power extraction under all conditions.

Although solar power is mainly covered, the principle applies generally to sources with variable power: for example, optical power transmission and thermophotovoltaics.

PV solar systems exist in many different configurations with regard to their relationship to inverter systems, external grids, battery banks, or other electrical loads.[5] Regardless of the ultimate destination of the solar power, though, the central problem addressed by MPPT is that the efficiency of power transfer from the solar cell depends on both the amount of sunlight falling on the solar panels and the electrical characteristics of the load. As the amount of sunlight varies, the load characteristic that gives the highest power transfer efficiency changes, so that the efficiency of the system is optimized when the load characteristic changes to keep the power transfer at highest efficiency. This load characteristic is called the maximum power point and MPPT is the process of finding this point and keeping the load characteristic there. Electrical circuits can be designed to present arbitrary loads to the photovoltaic cells and then convert the voltage, current, or frequency to suit other devices or systems, and MPPT solves the problem of choosing the best load to be presented to the cells in order to get the most usable power out.

Solar cells have a complex relationship between temperature and total resistance that produces a non-linear output efficiency which can be analyzed based on the I-V curve.[6][7] It is the purpose of the MPPT system to sample the output of the PV cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.[8] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors.

Solar inverters convert the DC power to AC power and may incorporate MPPT: such inverters sample the output power (I-V curve) from the solar modules and apply the proper resistance (load) so as to obtain maximum power.

The power at the MPP (Pmpp) is the product of the MPP voltage(Vmpp) and MPP current(Impp).
