This paper explores the e ects of rainwater harvesting (RWH) on aggregate household labor supply in areas prone to droughts. Using a Brazilian survey on rainwater harvesting, we nd that having a RWH infrastructure at the homestead increases household wellbeing through three channels: (i) a direct time allocation e ect since households spend less time fetching water from distant sources, the tim...

The use microalgae biomass for the production of biofuels has received great attention in the last decades. Microalgae biofuels could be important alternative to conventional biofuels since microalgae could be produced at high rates without the need of neither arable land, potable water or competition with food. However, the high energy intensive harvesting processes are limiting the commercial...

The fact that water is the most important factor of life on earth is not a new concept. Alteration and reduction in the amount of precipitation, population explosion and contamination of underground water pressurize governments severely to find solution for water resources. The air moisture is one of fresh water resources which has not been noticed and well exploited. In this study proper place...

Peridinin-Chlorophyll-α-Proteins (PCPs) are water-soluble light harvesting complexes from dinoflagellates. They have unique light-harvesting and energy transfer properties which have been studied in details in the last 15 years. This review aims to give an overview on all the main aspects of PCPs photophysics, with an emphasis on some aspects which have not been reviewed in details so far, such...
