DRIPS dew collection

A cheap plastic or metal conical funnel, about the diameter of a large dinner plate, collects dew and delivers water below the evaporation layer for deep root irrigation in arid environments. DRIPS is a free open source dew collection project for agriculture in arid regions. 

Family Planning and Subsistence Agriculture Key to Food Security

Papua New Guinea's high fertility rate is exerting pressure on land and food
production in a country where 80 percent of the population lives in rural
communities. But the National Agricultural Research Institute (NARI) argues that
traditions of subsistence agriculture provide a firm foundation to build food
security for a growing population.

Q&A: The World Must Learn From Smallholder Farmers

famers hold the key to making future development policies
sustainable.

Disappearing Groundwater and Desertification in Coastal Yemen

In Al Mujelis, on coastal Yemen, annual floods were the main source of groundwater recharge. With  the construction of bid diversion structures upstream, this recharge stopped downstream in Al Mujelis and groundwater tables fell rapidly. 

The annual sndstorms then took over the area and sand dunes buried farms and date orchards that were the main source of livelihoods. There has been constant out-migration ever since. The local population has fallen by 80%.
