The Climate Change Resistant Greenhouses Protecting India’s Crops Come Rain or Shine

Kheyti's resilient greenhouses are priced cheap enough for small rural farmers to afford.

A new affordable, climate-change-resisting greenhouse could help strengthen rural Indian farmers' defences against extreme weather conditions.

A new affordable, climate-change-resisting greenhouse could help strengthen rural Indian farmers’ defences against extreme weather conditions.

When farmers in rural India sow their seeds, there is no guarantee they’ll be harvesting them, with extreme weather conditions – exacerbated by climate change – frequently threatening their crops and livelihoods. 

Traditionally, farmers in the central Indian state of Telangara have relied upon the seasonal rains to keep their plants healthy in a region frequently hit with droughts and water shortages. However, in more recent years, the rains have been just as much a liability as a blessing, with heavy storms damaging crops and destroying entire harvests. These kind of extreme and variable weather conditions can financially ruin small farmers, with some even drawing links between the difficult conditions Indian farmers are facing and the dramatic increase in suicides.

A Greener Greenhouse

Kheyti, an India-based non-profit recently profiled by National Geographic, is hoping to assist small farmers in the region with a new type of greenhouse that can fortify crops against harsher weather conditions. Developed in conjunction with Stanford University and Northwestern University’s Institute for Sustainability and Energy, Kheyti’s greenhouse uses a new aluminum-coated cloth material which allows the structure to breathe, reducing interior temperatures and protecting crops against heatwaves and drought.

Additionally, the greenhouse employs a drip-irrigation system, which dramatically reduces water-usage by as much as ninety per cent, while the structure has been stress tested to ensure it can withstand Telangana’s volatile rainy seasons, as well as the invasion of insects they bring.

Kheyti’s greenhouses have also been developed with smaller farmers specifically in mind. Larger, traditional glasshouses generally cost somewhere in the region of 30,000 USD, placing them far outside the budgets of most small holding growers. Kheyti’s greenhouse only costs 2,500 USD, with the organization also working with banks to help farmers receive loans.

Small Greenhouse, Big Impact

Early indications appear to suggest Kheyti is not only effective at protecting crops, but also increasing yields. Farmers who tested the product reported they harvested five to eight times more crops when using the greenhouse over their unprotected fields. Furthermore, this output is achieved in the fraction of the space, with a small 235 metre square greenhouse producing the same as an acre (4,425 metre square) field.

A social element is also central to Kheyti’s approach, with the organisation developing community support networks across the region, as well as providing one-on-one training, support and logistical assistance – especially for single women farm owners. Since the success of their first solo female farm owner, the programme has been widened, providing an income, self-reliance and social mobility to more women in the region. The increased income derived from the greenhouses is also often used by farmers with families to help fund their children’s education.

Of course, although highly successful, Kheyti’s greenhouses are likely only a temporary solution for India’s rural farmers. Meaningful long term protection for Telangara’s small farmers can only likely come from major international efforts to curb climate change as well as a changes to how the agriculture industry is structured.

How African Farmers Are Taking a Rain Check On Climate Change

Climate change often affects those who have done the least the cause it, and who are least equipped to deal with its consequences. With ever-shrinking cycles of drought in Africa causing crops to fail, many small-scale farmers across the continent are being left high and dry.

No Rain? Small Farmers Covered Through Weather-based Insurance

The threat of drought is a constant for most farmers. Often lacking insurance cover altogether, small-hold farmers are particularly at risk from the consequences of a failed crop, which can mean not just reduced income, but also a reduced ability to feed their families and school their children.

New Approaches to Farming in the Age of Climate Change

A pre-release event for the upcoming report from the United Nation’s Intergovernmental Panel on Climate Change (IPCC) has presented a bleak future if inaction is still remains the biggest form of action.

The Privatisation of Seeds

Year in and year out farmers are losing the seeds from their own plants, and are forced to purchase them anew from seed providers. Monsanto has monopolized the seed market which has significantly limited the variety of plants available on the market. The consequences of which have had fatal effects on both our environment, and the farmers that harness crops from it.

Genetically Modified Crops

Genetically modified crops (GM crops) are crops which have had their DNA altered in a way that does not occur naturally. Individual genes which promote durability or nutritional value are transferred from one organism to another to create biologically robust plants.
