Few days ago, I did something that I have not done since I was a child in Israel. A simple activity that I forgot how much happiness it brought to my day, a small action I thought was long forgotten, but my hands and heart remembered the joy very well - I planted a tree.

My young Accra orange tree (that’s the way I named it) was a part of the Israeli initiative to commemorate world-wide the Earth Day.  At the same time, Israeli embassies across the globe commemorated Earth Day, highlighting the importance of this UN marked day, presenting the world with many innovative and cutting-edge solutions that Israel has provided to global problems, especially in these days of COVID-19.

The coronavirus pandemic has presented us with one of the most acute challenges of our generation. It has also, however, presented us with a unique opportunity to pursue economic recovery programs following the pandemic that incorporate strong sustainability and low-carbon measures. The world could effectively use the exit from COVID-19 to accelerate a green transition, and the commemoration of this year's Earth Day has thus taken on an even deeper meaning.

For over a decade, the UN Environment Programme has produced an "Emissions Gap Report" that analyzes the disparity between where greenhouse gas emissions should be by 2030, and where they are actually predicted to be. The 2020 report found that, despite a "brief dip" in greenhouse gas emissions caused by the pandemic's broad economic slowdown, the world is still headed towards a temperature rise of over 3 degrees this century, well above the goal of 1.5 degrees set out in the Paris Agreement. In fact, there is a direct link between environmental crises, climate change, and the novel coronavirus. Experts have found that global warming has led to the emergence of new infectious zoonotic diseases such as COVID-19, meaning that our current global pandemic is most probably tied to the grim environmental situation of our planet. This fact should serve as a strong and urgent call to action for all of us.

When it comes to climate innovation and sustainability, Israel can serve both as an example and as a provider of solutions to global problems. The country's arid and water scarce conditions, combined with its entrepreneurial and problem-solving spirit, have made Israel a leader in the field of environmental innovation. Drip irrigation and the development of resistant, fortified crops are world-renowned and highly sought after technologies that were actually originally developed in Israel.

Israel is a global water powerhouse. The country holds the world record for water reuse, recycling almost 90% of its wastewater for use in agriculture. It also has one of the most unique national water systems in the world, with some 80 percent of its drinking water being desalinated saltwater. Over a century of experience in reforestation have also made Israel a leader in the reforestation of semi-arid areas, expertise that will only grow in value as large-scale tree planting and other nature-based solutions become ever more prevalent as methods of mitigating against the effects of climate change.

Israel has an exceptional set of assets that mean it is well-placed to make a unique contribution worldwide when it comes to pursuing green recovery programs from COVID-19. Its cutting-edge technologies and decades of practical experience were all borne of the demanding environmental challenges that Israel faced from the very outset of its statehood, and the solutions it developed to meet those challenges could now serve the world well.

By opening the “Jerusalem Garden” and planting 25 fruit trees at the La Wireless Cluster of Schools we wished to provide the schoolchildren with a safe and conducive environment for learning and leisure and encourage them to contribute to Mother Earth. But planting trees is not enough: we have to invest in green innovation and find solutions for the challenges ahead of us. Thus, for the third time we are launching the annual Israel Green Innovation Competition (IGIC). Together with the Ghana Garden and Flower Movement, we are calling Ghanaian Start Ups to find solutions for challenges in agriculture and horticulture in Ghana. The winner of the 2021 IGIC will be awarded with a fully paid trip to Israel, including meetings with potential investors and internationally acclaimed Israeli Startups that will help the winner commercialize.

Giving back to mother earth is our answer to all of the hardships that the coronavirus pandemic has inflicted upon us. Israel is willing to share its experience and knowhow with every country in the world and Ghana is a leading one; we only have one planet, and we must all work together to protect it.
