8 March 2018, The Conversation Why aren’t Australia’s environment laws preventing widespread land clearing? Australia has national environment laws – the Environment Protection Biodiversity Conservation Act (EPBC Act). Yet given the staggering rates of land clearing taking place, resulting in the extinction and endangerment … Continue reading →

21 July 2017, Climate Home, Indian farmers mourn dead after debt crisis turns violent. Six protesters were killed in the Mandsaur district of Madhya Pradesh in June. Meet the bereaved families driven to despair by erratic weather and a tough market. Abhishek Patidar was 17 years old when he died. A farmer’s son, he had planned on becoming a doctor. “Abhishek studied in the 11th grade,” said his mother Alka Patidar, proudly. Her eldest son had only finished 8th grade before he started working the family farm. Abhishek, the youngest of four children, looks like his mother. His eyes follow the same curvature; his skin is the same shade of tan. Abhishek was killed at a protest on 6 June, 2017, when Indian police opened fire on the crowd. India’s farmers are in crisis. Their frustrations, simmering quietly after the harvest, became palpable in a 10-day long protest in June. Thousands of farmers in the Mandsaur district of central India’s Madhya Pradesh had turned up in the towns of Piplia Mandi and Bahi Phanta to demand fair prices for a season’s worth of work. Abhishek went along with several other young men from his village. The protests started out peacefully, but turned ugly a few days in, when a scuffle broke out between better-off business owners in the area and debt-ridden farmers. On the sixth day, the violence climaxed when police, trying to control the crowd, fired their weapons. Five protesters were killed on the spot and a sixth man later died of injuries sustained in the clash. Read More here

20 July 2017, The Conversation, Farming the suburbs – why can’t we grow food wherever we want? Food provides the foundations for human flourishing and the fabric of sustainability. It lies at the heart of conflict and diversity, yet presents opportunities for cultural acceptance and respect. It can define neighbourhoods, shape communities, and make places. In parts of our cities, residents have embraced suburban agriculture as a way to improve access to healthier and more sustainably produced food. Farming our street edges and verges, vacant land, parks, rooftops and backyards is a great way to encourage an appreciation of locally grown food and increase consumption of fresh produce. Despite these benefits, regulations, as well as some cultural opposition, continue to constrain suburban agriculture. We can’t grow and market food wherever we like, even if it is the sustainable production of relatively healthy options. While good planning will be key to a healthier, more sustainable food system, planning’s role in allocating land for different uses across the city also constrains suburban agriculture. Two steps towards healthier food systems: Making our food systems healthier and more sustainable requires a two-step approach. First, we need to fortify the parts of the system that enable access to healthy food options. Second, we need to disempower elements that continuously expose us to unhealthy foods. Although food is a basic human need, the way we consume food in many countries, including Australia, is harmful to the environment and ourselves. Many of us don’t eat enough fresh and unprocessed foods. The foods we do eat are often produced and supplied in carbon-intensive and wasteful ways. Primarily through land-use zoning, town planners can help to shape sustainable and healthy food systems.

28 June 2017, The Conversation, The world’s tropical zone is expanding, and Australia should be worried. The Tropics are defined as the area of Earth where the Sun is directly overhead at least once a year — the zone between the Tropics of Cancer and Capricorn. However, tropical climates occur within a larger area about 30 degrees either side of the Equator. Earth’s dry subtropical zones lie adjacent to this broad region. It is here that we find the great warm deserts of the world.Earth’s bulging waistline Earth’s tropical atmosphere is growing in all directions, leading one commentator to cleverly call this Earth’s “bulging waistline”. Since 1979, the planet’s waistline been expanding poleward by 56km to 111km per decade in both hemispheres. Future climate projections suggest this expansion is likely to continue, driven largely by human activities – most notably emissions of greenhouse gases and black carbon, as well as warming in the lower atmosphere and the oceans. If the current rate continues, by 2100 the edge of the new dry subtropical zone would extend from roughly Sydney to Perth. As these dry subtropical zones shift, droughts will worsen and overall less rain will fall in most warm temperate regions. Poleward shifts in the average tracks of tropical and extratropical cyclones are already happening. This is likely to continue as the tropics expand further. As extratropical cyclones move, they shift rain away from temperate regions that historically rely upon winter rainfalls for their agriculture and water security. Researchers have observed that, as climate zones change, animals and plants migrate to keep up. But as biodiversity and ecosystem services are threatened, species that can’t adjust to rapidly changing conditions face extinction. In some biodiversity hotspots – such as the far southwest of Australia – there are no suitable land areas (only oceans) for ecosystems and species to move into to keep pace with warming and drying trends. We are already witnessing an expansion of pests and diseases into regions that were previously climatically unsuitable. This suggests that they will attempt to follow any future poleward shifts in climate zones. Read More here
