How civil society organizations can help tackle pandemics

World Economic Forum  online


COVID-19 has been the foremost global health challenge over the last year and a half and has affected all spheres of life and development. As of 7 July 2021, the world has registered a total of over 184 million COVID-19 cases, while confirmed deaths worldwide have been reported at over 3.99 million. It is envisaged that the Low and Middle Income Countries (LMICs) have been and will continue to be hit harder by the pandemic as a result of limited healthcare capacity and inadequate infrastructure, as well as difficulties in maintaining social distancing. Apart from its direct health consequences, COVID-19 has left communities in LMICs with dire economic consequences. The World Bank estimates that about 120 million people have been pushed into poverty due to COVID-19 in the last year or so.

Making arid Rajasthan water sufficient, using age-old methods

Forbes India  online


Earlier, farming was entirely dependent on the monsoon; but now the soil absorbs enough water for villagers to produce a kharif (winter) crop. “When the organisation first introduced khadins, we used to hear stuff like, ‘Yeh kitna chota hai, isse kya hoga [this is so small, what can it do]?’ But as people saw changes, they started adopting this technique. We have constructed about 5,000 khadins now,” says Prakash Tyagi, executive director, Gravis.

Mental health a growing public priority in India

HelpAge International  


Growing prevalence of mental health disorders in older populations is an emerging public health challenge in India. There are some 3.7 million people in the country currently living with dementia, according to Dementia India Report of 2010 (pdf). This figure is expected to double by 2030 and, with the number of older people projected to grow to 325 million by 2050, the country is at a great risk of an aggravated mental health challenge, while other conditions, including depression, delirium and anxiety, are also consistently rising. Particularly at risk are those older people living in remote, rural settings who, amid poverty, lack of literacy and poor health services, are especially vulnerable to mental health conditions.

Sexually-transmitted diseases in older age are an area of neglect

HelpAge International  


HIV's disconnect with people in older age in terms of programmes, priorities and strategies has increasingly been discussed over recent years. Yet, conversations on sexually-transmitted diseases overall remain more neglected. Despite the vast number and complexity of sexually-transmitted diseases, older age is often considered a stage in the life course when they don't matter. Syphilis, chlamydia and gonococcal infections have been found to be very common in people over the age of 50, affecting people into their 60s, 70s and beyond.
