Doenças de inverno do relvado

No inverno, os dias encurtam, a chuva instala-se e o frio faz-se sentir, diminuindo naturalmente o tempo que passamos no jardim a desfrutar da relva e proporcionalmente a nossa disponibilidade habitual em alturas mais quentes.

Uma vez que as relvas ditas de verão estão inativas nesta altura do ano, vamos centrar este mês a nossa atenção nos relvados das chamadas relvas de inverno.

Não nos devermos descuidar com os cortes da relva, que devem ser entre 0,5 a 1 cm superiores ao realizado no período de primavera/verão, um período que obriga a trabalhos de corte e de manutenção diferenciados. A relva cresce (felizmente), menos neste período mas, como tem que ser cortada sem chuva nem sempre é possível cortar com a periodicidade necessária para remover só 1/3 da folha, no máximo. No caso de a sua relva estar demasiado alta, suba o corte da sua máquina para a altura máxima.

Dê um primeiro corte para aparar e, de seguida, baixe o corte para a altura recomendada e faça uma segunda passagem, cruzada a 45° ou 90° em relação à primeira. Execute a adubação, com o adubo que selecionou, na quantidade recomendada (consulte as recomendações no nosso artigo de outubro) e com a periodicidade que esse adubo exigir e mantenha-se atento aos sintomas e sinais das principais doenças de outono/inverno que atacam o seu relvado.

As doenças mais comuns

Embora existam, infelizmente, muitas mais, vamos abordar neste artigo aquelas que mais tenho enfrentado em relvados de jardins, ao longo da minha vida profissional. As doenças conhecidas vulgarmente como helminthosporoses (apesar dos fungos que a causa serem hoje classificados como Drechslera sp. e Bipolaris sp.) são favorecidas pelo excesso de humidade e temperaturas baixas.

A relva definha, parecendo que se derrete, o chamado melting out dos anglo-saxónicos. Aparecem manchas castanhas a castanho-avermelhado nas folhas e quando estas manchas são transversais a toda a largura da folha cortam a passagem dos nutrientes para a parte superior levando a que esta seque desde a ponta até à mancha.

Nos relvados, não formam manchas definidas, mas o relvado vai definhando por zonas que vão alastrando. Evite fazer herbicidas à base de 2,4 –D, MCPP e dicamba nos períodos húmidos de outono, já que estudos demonstram um efeito potenciador sobre o ataque destes fungos.

Os ataques de Rhizoctonia sp., causam nesta altura do ano (tempo frio e húmido) a chamada doença da mancha amarela (yellow patch). Os relvados ficam com manchas ou anéis amarelados (que podem ir de diâmetro de 15 cm a um metro) e as folhas individualmente ficam com manchas amarelo palha, com contorno castanho escuro ou avermelhado. Por ser uma doença favorecida por altos níveis de azoto, evite adubar excessivamente o relvado com adubos de libertação rápida em condições de tempo húmido.

Top 10 Documentaries For Landscape Architects

There is a certain persuasion in documentaries that is not often found in books.

Sometimes actually seeing, visually dissecting, a narrative can be more inspiring and engaging than words on a page.

The documentaries below can be quite different in their style and delivery – what is important however, is that they all seek to explore man’s relationship with his (natural or unnatural) environment. And as a Landscape Architect, it couldn’t hurt to see a few….

Here we take you through 10 of the best (in our opinion) documentaries out there, covering topics such as urban design, landscape architecture, sustainable design, biophilia, climate change and urban planning.

These are films that will make you think, generate discussion within your own mind and make you question your own design decisions.  Indeed, these are films to watch with colleagues, like minded friends and classmates.

Get the popcorn, its movie time!

10. The Big Uneasy (2010)

Complete with New Orleans jazz and John Goodman, Harry Shearer looks at what happened when Hurricane Katrina hit the US city. Yet this is NOT a film about a natural disaster. What is revealed is that the flooding was caused by more than four decades of misguided construction and design. At a time where floods are causing trouble world over, and landscape architecture is driven towards WSUDS – this is gripping, damning stuff.

9. The Age of Stupid (2009)

This piece of docu-fiction weaves together six documentaries, which are presented by ‘the archivist’ in a tale of hubris and …stupidity. It highlights that climate change and global warming are not just real, but unless true change is made, further consequences will be felt in our lifetime with devastating effects.

8. The End of Suburbia (2004)

Cheap and abundant energy is coming to an end – a nation on wheels, a generation of sub-urbanites will have to change. Half of the American population lives in suburbia. Will peak oil reverse globalization? Will a more holistic, localized form of development be the future?

7. Urbanized (2011)

Not groundbreaking but this film is generally a good overview of the issues facing cities, and thus the world, as we see the planet become more urbanized. Travelling from Mumbai, to Brasilia, to New York and Germany, different levels of urbanity and urban design are looked at; ranging across large-scale infrastructure to low-level interventions with community involvement.

6. Edible City: Grow the Revolution (2012)

There is an ever-increasing need for food to become an intricate part of our landscape. This inspiring documentary not just examines the why, but mainly focuses on established examples of how it is possible to work with nature and our cities in order to produce food for local people.

5. Manufactured Landscapes (2006)

Through the photography of Edward Burtynsky, Manufactured Landscapes, provides us with a haunting, though often visually stunning, image of the ’landscapes of our time.’ Burtynsky examines the effect industrialization and manufacturing has on our world and asks if the landscapes of our time are the ones we disrupt in the pursuit of progress?

4. The Nature of Cities (2009)

As our world becomes ever more urbanized we must find a way to integrate ourselves within nature in order to maintain our survival. Professor Timothy Beatley travels across America and Europe talking to planners, landscape architects, ecologists and communities. There are some poignant insights offered by Richard Louv (he who coined the term ‘nature-deficit-disorder’) and Dr. Stephen Kellert from Yale (Biophillic Design).

3. Biophilic Design: The Architecture of Life (2011)

Dr. Stephen Kellert advocates that we designed ourselves in to many of the messes we are presented with today, and thus we can design ourselves out of them. This can be done by biophilic design. The documentary explores how nature and architecture have come together to create hospitals were patient recovery rates are greater and offices where employees are more productive due to a connection with nature and the environment.

2. The Social Life of Small Urban Spaces (1988)

In this short film, William H. Whyte examines why certain spaces are popular and others not. A seminal piece of work that changed the way our public spaces are designed and built; namely that places should be designed for people. Vitally, it is as relevant today as it was 30 years ago.

1. A Convenient Truth: Urban Solutions from Curitiba (2006)

Sick of all the depressing why we should change documentaries? Want an uplifting how to/it is possible one? Then watch this. Curitiba, Brazil has been undergoing major changes since the 1970s in transportation, recycling, affordable housing and implementation of green space.Inspiring and hopeful, a true example of how a determined population and supportive governance can reverse or at least, negate the negative effects of urbanization.

These are a mere ten in a colossal range of documentaries currently depicting the problems society faces; peak oil, flooding, food crises and some that offer hopeful solutions.

What is their message? To galvanize us into making a change. What ones motivate you?

Construção da Herdade da Cegonha arranca dentro de dois anos

Construção da Herdade da Cegonha arranca dentro de dois anos
A Placan vai investir 150 milhões de euros na «Herdade da Cegonha – Lake, Golfe and Spa Resort», junto à barragem do Alvito, em pleno Alentejo. Em declarações à VI-News, o administrador da promotora, Cândido Monteiro, revelou que neste momento está em curso a elaboração e desenvolvimento do Plano de Pormenor, bem como toda a definição do conceito do “resort”. O início das obras está previsto para arrancar dentro de dois anos, sendo de oito meses o «horizonte temporal para o desenvolvimento e conclusão do plano contratualizado».

A promoção das boas práticas e a preocupação ambiental valeram à Herdade da Comporta o prémio “I am Green”, atribuído no âmbito da participação no Green Festival, que decorreu no Centro de Congressos do Estoril, de 18 a 25 de Setembro.
Para a decisão do júri pesou o cumprimento de todos os critérios definidos para o concurso, nomeadamente os materiais utilizados na construção do stand - marcado pela originalidade, já que recriava uma casa tradicional da região, feita de madeira e colmo -, a iluminação e o tipo de brindes entregues aos visitantes (pen USB e pouco material impresso), a realização de acções de ambientais (com destaque para actividades lúdicas de sensibilização para crianças) e a certificação de SGS, com a correcta utilização dos resíduos.Além do reconhecimento público das boas práticas sustentáveis levadas a cabo pela empresa, a Herdade da Comporta foi premiada com uma consultoria em sustentabilidade no valor de cinco mil euros.O Green Fest, o evento português de referência na área da sustentabilidade é uma organização da BCSD Portugal - Conselho Empresarial para o Desenvolvimento Sustentável e regressa em 2010, novamente no Centro de Congressos do Estoril, entre 10 e 17 de Setembro.

Entre 163 equipas de 25 países foi o arquitecto paisagista português João Ferreira Nunes, que coordena o atelier PROAP, quem venceu o concurso

Entre 163 equipas de 25 países foi o arquitecto paisagista português João Ferreira Nunes, que coordena o atelier PROAP, quem venceu o concurso de ideias para o parque urbano da área florestal de Valdebebas, e que será o maior de Madrid.
Apoiado pelos paisagistas espanhóis Bet Figuera e o atelier Opera, João Ferreira Nunes irá intervir numa área de aproximadamente 80 hectares, correspondente à expansão urbana a norte de Madrid, promovida pela municipalidade da capital espanhola.
A equipa intitulou de "Sol y Sombra" a sua proposta, uma vez que, refere, "representa um dos temas do parque, um tema que nos fala dos contrastes do lugar, e que o parque interpreta através das cumplicidades estabelecidas entre as grandes áreas de clareira e as zonas de bosque, entre os taludes densamente revestidos e o desafogo da linha de cumeeira, através das superfícies de água e das suas vibrações e através da plasticidade das estruturas inertes do parque, muros maciços brancos e lisos, que constituem represas que limitam pavimentos, que suportam terras, que albergam funções, como muros habitacionais".
Do ponto de vista da organização do espaço, serão intercaladas zonas de clareira e zonas de bosque, a forma mais tradicional da paisagem europeia, reproduzida aliás em parques notáveis, como o da Fundação Calouste Gulben- kian.
Este padrão de cheio e vazio terá diversos momentos e formas: junto à malha urbana madrilena já existente, o bosque será pouco denso e o destaque pertencerá às clareiras. Na transição para as futuras habitações da expansão da cidade por Valdebebas, o tema será tratado de forma mais urbana, com recurso a muros, passeios e zonas de recolha de águas pluviais que darão origem a pequenos lagos.
Um antigo caminho, que foi utilizado para transporte de animais neste pedaço de Madrid, voltará a ganhar vida, integrando-se num troço do parque, em forma de folha de árvore, que incorporará as zonas de bosque mais densas de toda a área tratada pelo urbanista português e sua equipa. À semelhança de uma folha, este excerto do parque será dividido a meio por uma nervura, correspondendo a uma linha de cumeada que servirá, também, de miradouro.
Finalmente, e aproveitado a topografia e movimento natural das águas no terreno, serão criadas zonas húmidas, como lagoas, que culminarão numa praia artificial. Este grande momento de toda a intervenção terá características de veraneio e lazer. Sobre a água nascerá um anfiteatro e, nas cercanias, um centro de informação ambiental, restaurantes, cafetarias e praças.
Consciente da cultura urbana das grandes cidades e de Madrid em particular, João Ferreira Nunes entende que o tema "Sol Y Sombra", que motivou o projecto, também se estenda às intervenção dos utentes do parque. Assim, adivinha para os seus "muros brancos, onde se desenham sombras," um futuro em que "se desenham também graffiti, signos e mensagens, retirados ano após ano e transformados em frutos do parque, para darem lugar, uma vez mais, ao branco...
