How SERVIR is helping Southeast Asia adapt to variable rainfall

In the USA, the agriculture sector just isn’t resistant to floods and droughts. However when these disasters hit, the system is designed to be sturdy sufficient to bounce again shortly. With an economic system that is determined by agriculture, many protections are in place to assist farmers keep afloat, even after main disasters.

In the meantime in Southeast Asia, more and more variable rainfall is making life troublesome for farmers. As rainfall turns into much less predictable, dry seasons broaden, threatening the well being and high quality of crops across the area. Southeast Asia is determined by these crops, particularly rice, which brings in billions of {dollars} yearly worldwide. With this menace to the area’s economic system, local weather change has introduced uncertainty to the group stage.

Farmers that rely upon rainfall for crop yield are extra negatively impacted by the much less predictable situations and are due to this fact extra susceptible as local weather change worsens. To make issues worse, these farmers lack the identical protections from which US farmers profit. With help from organizations such because the Asian Catastrophe Preparedness Heart, SERVIR scientists like Dr. Narendra Das are working with our regional hubs and different stakeholders on fashions that can higher predict crop yields within the face of local weather change.

“As the worldwide inhabitants is growing, local weather change can be taking place,” Das defined. “To [help with] meals safety, we have to have a greater understanding of how a lot crop yield we’re going to get in any given season and what’s the standing of the drought.”

Das is an affiliate professor of hydrology and distant sensing at Michigan State College and a member of SERVIR’s Utilized Sciences Staff. SERVIR is a joint program of NASA and the U.S. Company for Worldwide Growth. It collaborates with geospatial organizations worldwide to assist communities in Asia, Africa, and Latin America deal with environmental challenges utilizing information from Earth observing satellites from NASA and different house companies. These sources are designed to assist authorities make better-informed choices about challenges like water sources and catastrophe administration.

This venture makes use of Earth observations to forecast crop yields a number of months upfront, giving governments in Southeast Asia time to arrange if forecasts predict a decrease yield. Utilizing a software known as the Regional Hydrologic Extremes Evaluation System (RHEAS), the Mekong Drought and Crop Watch (MDCW) software was developed to assist visualize and handle the info on droughts and the way they may impression crop manufacturing.

RHEAS is a hydrologic modeling software developed at NASA’s Jet Propulsion Laboratory, College of Massachusetts Amherst, and Michigan State College that makes use of satellite tv for pc imagery to routinely present customers with a present take a look at water sources and forecasting capabilities. The MDCW software localizes and streamlines the acquisition of this information, routinely amassing and displaying it. This makes it extra accessible to audiences with out a background in distant sensing.

Das has had a lifelong curiosity in distant sensing however has encountered distinctive challenges in making use of these expertise to fast wants worldwide. He talked candidly in regards to the strategy of capability constructing and interesting with stakeholders in new methods, together with the difficulties of getting anecdotal and “on-the-ground” information from communities.

“Getting this information was very difficult,” he stated. “As a result of generally the nations are very protecting of those datasets, and so it’s a must to go and persuade them.” Das and his crew of scientists within the US and the SERVIR-Mekong hub labored with specialists in Southeast Asia to construct a software that addressed their wants instantly. These specialists helped to outline the wants of the software and co-developed the science behind it.

Das provides that language limitations made this course of much more troublesome. That is the place the native experience and belief constructed between the SERVIR-Mekong hub and customers within the area got here in. Collectively, they have been capable of present constant experiences on crop yields that shifted the way in which authorities officers in these nations made choices.

He smiled as he added, “Now, individuals see the worth of this venture.”

And so they do: a number of governmental organizations depend on Das’s work to watch and report on crop yields in regular day-to-day operations. The Mekong River Fee and the Vietnam Academy of Water Assets are simply two of the various organizations utilizing this information to enhance their water useful resource administration. Das anticipates that as increasingly communities are made conscious of the ability of Earth observations for monitoring drought situations and predicting crop yield, there shall be a requirement for this venture to be replicated. Past the successes in Southeast Asia, Das helps an analogous venture in Kenya that displays drought situations and maize yields.

As Das strikes on to different initiatives, SERVIR’s Mekong hub will proceed supporting this venture to raised the lives of farmers across the area. Scientists similar to Susantha Jayasinghe and Nguyen Hanh Quyen – respective theme leads for agriculture and meals safety and land cowl and ecosystems – have labored with Das on this venture and have the experience to proceed implementing it. Das is happy for the venture to proceed sooner or later, and presumably broaden as increasingly organizations start to grasp the extent of its capabilities for serving to communities adapt to and mitigate local weather change impacts.
