GENE EDITING A MORE ELEGANT WAY OF TACKLING CROP DISEASES THAN SPRAYING MORE PESTICIDES

GENE EDITING A MORE ELEGANT WAY OF TACKLING CROP DISEASES THAN SPRAYING MORE PESTICIDES 

...CRISPR revolution opens door to ‘disaster-proof’ crops, BBC reports 

Traditional crop breeding can be time-consuming and laborious,Brad Ringeisen, the executive director of the Innovative Genomics Institute (IGI) at the University of California (Berkeley and San Francisco), believes that gene editing using tools like Crispr-Cas9 is the most impactful way of ensuring that crops can withstand disasters, BBC reports. 


“It speeds up the innovation cycles. It is a precise tool.”

Mr Ringeisen summarises the IGI’s work on disease resistance in crops: “There are a tremendous number of emerging diseases, and climate change is not helping this.”

He says gene editing is a more elegant way of tackling disease than spraying more pesticides.


As well as disease resistance, the IGI is working on drought tolerance. A rice variety that has been gene edited to reduce the number of pores on leaves, reducing water loss, is now in field trials in Colombia. Such tests are necessary to make sure that gene edits don’t lead to unforeseen side effects in practice.


The IGI’s project is one of a number of scientific efforts to make rice less vulnerable to unpredictable water cycles. Scientists at the International Rice Research Institute in the Philippines, for example, have developed a "scuba rice" strain that can withstand weeks of submergence in water during floods.

ZAAB QUESTIONS GOVERNMENT'S SILENCE ON PBR BILL

  ZAAB QUESTIONS  GOVERNMENT'S SILENCE ON PBR BILL  By Alfonso Kasongo  A collaborative network of concerned citizens, civil society groups, faith and farmer-based organisations, working together to strengthen the growing movement for agroecology and food sovereignty has questioned government's failure to avail the proposed new Plant Breeders Rights (PBR) Bill.  Zambia Alliance for Agroecology and Biodiversity (ZAAB) maintains that controversial Bill is inappropriate for the country and must not be enacted as it aligns the country to the International Union for the Protection of New Varieties of Plants (UPOV) 1991 standards. The Consortium fears that once proposed PBR Bill is enacted in its current form, the new seed law may trigger price increase and corporate capture of seeds, as well as  country's food system.  The Alliance argues that government through the Seed Control  Certification Institute SCCI  has never presented the actual changes...

ZAMBIA LISTED AMONG 34 COUNTRIES WORLDWIDE THAT EXPERIENCED DIGITAL AUTHORITATIVE RULE

Image
  By Alfonso Kasongo  The shutdown of internet to block access to social media during the 2021 general election has earned Zambia a slot among 34 countries worldwide that experienced digital authoritative rule last year. According to a research conducted by Keep It On ,182 internet shutdowns from 34 countries were last year recorded and are documented. Sadly 19 of the 34 countries are African countries, an indication of the return of the digital authoritatism. The report  discloses that the Zambian authorities shutdown the Internet during the the tight 2021 general election to block access to social media platforms which  include among others WhatsApp, Facebook, Twitter and Instagram.   The report however ,suggests that the country experienced digital authoritative rule which undermined the democracy of the country.    It further notes with pleasure that the shut down was fought swiftly by Chapter One Foundation through the court of law and that the Hi...

ZAMBIA'S CLIMATE FINANCING UTILISATION LACKS TRANSPARENCY, ACCOUNTABILITY

ZAMBIA'S CLIMATE FINANCING UTILISATION LACKS TRANSPARENCY,  ACCOUNTABILITY ...hence prone to corruption risks,posing threats against building climate change resilience, TIZ report reviews. By Alfonso Kasongo Zambia's quest to remain climate change resilient might veer off course, if gaps such as weak climate regulatory frameworks, corruption risks and lack of transparency in the management of climate financing remain unaddressed. Ànd tackling of how the country supports mitigation and adaptation to climate change remain critical to building resilience to the worst effects. Climate resilient is generally defined as successfully copying with and managing the impacts of climate change while preventing those impacts from growing worse. This year's unprecedented global temperatures and stark devastating of climate change stress the urgency requirement for Zambia and many other countries to build climate resilience, hence the need for strong regulatory framework and transparency ...
