DEFRA has failed to file dozens of reports on environmental legislation, which it is legally bound to do. The reports are essential because they show the public and campaign groups how effective laws are at achieving their goals. The findings are published in a report by the Office for Environmental Protection, or OEP, which was set up to monitor how well environmental regulations are working and whether government departments are implementing them properly. The Food Standards Agency has confirmed that one person has died following an outbreak of listeria. It is warning people not to eat any Baronet soft cheese products after high levels of listeria monocytogenes were found, although the death has not been specifically linked to this cheese. The Old Cheese Room which produces Baronet told us in a statement that they have now changed their testing regime, and none of their other cheeses has been affected. A new report suggests supermarkets and the government need to do more to reduce the environmental impact of agriplastics. That's things like polytunnel plastic, plastic mulch - the sheeting that's put on the fields to keep the soil warm - irrigation pipes, fertiliser bags and even the microplastics present in fertiliser pellets and some composts. The Environmental Investigation Agency report says government policy around the production and disposal of agriplastics is lacking. As we continue our week-long look at farm waste, we visit one firm in South Wales which is turning waste farm plastic into products. They collect and clean materials like wrapping for silage or feed packaging, it's then turned into pellets which can be used to make things like fence posts.

Dartmoor MPs are calling for an 'independent process' to work out the balance between farming and conservation on the moors. This follows what some called 'rewilding by the back door' - Natural England's recent decision not to renew some farmers' Countryside Stewardship agreements on the moor, unless the number of livestock was significantly reduced, to try to improve the condition of some protected areas. The three conservative MPs for the area say that despite a working group being set up last year to achieve consensus, Natural England has gone ahead without talking to either the Commoners Association, the National Park or the Dartmoor Owners Association. From plastic bale wrap to out of date agrochemicals - what happens to the waste from farms? We'll be finding out all this week. And more than a quarter of urban air pollution starts on farms. A team from University College London looked at particulate pollution in cities, and found that agriculture created, for instance, 38% of Leicester's and 25% of London's in 2019.

As inflation soars, one Devon crab producer says its fuel costs have gone up more than 500% in the last five years, with additional costs for exporting to the EU since Brexit. However a growth in demand from the USA and Asia means they're still optimistic. The Duchy of Cornwall is to phase out the farming of Pacific oysters in all the estuaries it owns. Several oyster farms in Devon and Cornwall now face closure. They farm Pacific oysters which are classed as an invasive, non-native species. Defra has introduced tighter restrictions around oyster farms to prevent the spread of Pacific oysters and protect native ones. The shellfish industry says the policy is misguided. Fishing communities are calling for the government to open a new inquiry into the die-off of crabs and lobsters on England's North East coast. Fishing crews say further dredging in the area is causing problems and is now affecting prawn catches. A previous Defra inquiry concluded dredging was not to blame and say they've ruled out further investigations The new Precision Breeding Act has become law. It will allow the use of gene-editing technology to create new plant varieties. Defra says the new law will not allow for the indiscriminate use of gene-editing technology, but campaign groups, like GM Freeze, say it could have unintended consequences. Scottish grouse moors will have to be licensed under proposals in a new bill. The Scottish Government says the Wildlife Management and Muirburn Bill, if passed, will tackle the persecution of birds of prey. It would also bring in greater restrictions around muirburn, the controlled burning of heather, on peat soils. Gamekeepers say the changes would effectively put shoots out of business.

The Duchy of Cornwall is to phase out the farming of Pacific oysters in all the estuaries it owns, meaning several oyster farms in Devon and Cornwall are now facing closure. It comes after DEFRA introduced tighter restrictions around creating and expanding oyster farms in English waters with the aim of preventing the spread of Pacific Oysters and protecting native ones, which are now only found in a few strongholds. Pacific Oysters - the type used in oyster farms - are classed as an invasive, non-native species. Scottish grouse moors will have to be licenced under proposals in a new bill introduced to the Scottish Parliament. The Wildlife Management and Muirburn Bill - if it's passed - will implement the recommendations of the Werritty Report, which was published in 2019 and was a sweeping review of the impact grouse moor management is having on Scotland's wildlife. And changes to the rules around gene editing of crops take effect in England as the new Precision Breeding Act has become law. It will allow the use of gene editing to create new commercially available plant varieties, diverging from EU law. Similar rules on animals are due to be introduced at a later date.

The Blue Sea Food Company sells Devon crab in the UK and around the world... and says their fuel costs have gone up more than 500% in the last five years... with additional costs for exporting to the EU since Brexit. But, a growth in demand from the USA and Asia means they're still optimistic. Spain is experiencing a drought. In Catalonia, the use of water for irrigation is subject to a mandatory 40% reduction. So with veg shortages already evident on UK supermarket shelves, could this exacerbate the situation? And a £1million training facility is being launched at Hadlow College in Kent, with funding from the Government to create a new vineyard and orchard. But can it really prepare students for the reality of life in an industry that's facing so many challenges? Presented by Charlotte Smith Produced for BBC Audio in Bristol by Heather Simons
